In addition, the present invention provides examples of various specific processes and materials, but one of ordinary skill in the art may recognize the applicability of other processes and/or the use of other materials.

Hereinafter, a control method of the air conditioner 100 according to an embodiment of the present invention is described with reference to the accompanying drawings.

As shown in fig. 1 and 2, the air conditioner 100 includes a casing 1, a heat exchanger assembly 2, and a first fan assembly 4, a first air duct 12 is defined in the casing 1, a fresh air inlet 12a, an indoor air inlet 12c, and an air outlet 12b that are communicated with the first air duct 12 are formed on the casing 1, the heat exchanger assembly 2 further includes a first heat exchanger 22, the first heat exchanger 22 and the first fan assembly 4 are all disposed in the first air duct 12, the first fan assembly 4 can drive an airflow in the first air duct 12 to flow, and the first heat exchanger 22 can exchange heat with the airflow in the first air duct 12. For example, when the first fan assembly 4 and the first heat exchanger 22 are both operated, indoor air may flow into the first air duct 12 through the indoor air inlet 12c, and/or outdoor air (i.e., fresh air) may flow into the first air duct 12 through the fresh air inlet 12a, i.e., indoor air and/or outdoor air flows into the first air duct 12 to exchange heat with the first heat exchanger 22, and the air after heat exchange flows out through the air outlet 12b, so as to enrich the operation mode of the air conditioner 100.

Therefore, if outdoor air flows into the first air duct 12 through the fresh air inlet 12a, air circulation between the indoor environment and the outdoor environment is realized, and the comfort of the indoor environment is improved; if the indoor air flows into the first duct 12 through the indoor air inlet 12c, it is convenient to promote the air circulation of the indoor environment.

As shown in fig. 1 and 2, the air conditioner 100 further includes an electric auxiliary heating assembly 5, the electric auxiliary heating assembly 5 includes a first electric auxiliary heater 52, and the first electric auxiliary heater 52 is disposed in the first air duct 12, so that the first electric auxiliary heater 52 operates to heat the air flow in the first air duct 12, so as to ensure the heating capability of the air conditioner 100.

That is to say, the first air duct 12 may be used only as a heat exchange air duct of the air conditioner 100, or only as a fresh air duct of the air conditioner 100, and of course, the first air duct 12 may also simultaneously realize heat exchange (for example, heating and cooling) and fresh air functions of the air conditioner 100, and when the first air duct 12 simultaneously realizes the heat exchange and fresh air functions, the heat exchange air duct and the fresh air duct of the air conditioner 100 may share the first electrically-assisted heat 52.

Compared with the prior art, the air conditioner is internally provided with the heat exchange air duct and the fresh air duct, the heat exchange air duct can realize a heating function, the fresh air duct is used for only realizing a fresh air function, the heat exchange air duct and the fresh air duct are respectively internally provided with the electric auxiliary heat, when the electric auxiliary heat in the heat exchange air duct and the fresh air duct is simultaneously started, the power of the whole air conditioner is higher, the power consumption is higher, the heating loss of a connecting circuit of the air conditioner is higher, the temperature of the connecting circuit is increased, and the service life aging degree of the connecting circuit is accelerated; air conditioner 100 in this application can effective reduce cost, saves the dedicated electricity in air conditioner new trend wind channel and assists the heat for the power of the dedicated electricity in new trend wind channel and assisting the heat can be subtracted to the maximum power of the 100 complete machines of air conditioner, has reduced air conditioner 100's energy consumption, reduces the temperature of the 100 interconnecting link of air conditioner, slows down interconnecting link's ageing rate, guarantees air conditioner 100's life.

As shown in fig. 3 to 7, the air conditioner 100 further has a first operation mode in which the fresh air inlet 12a is opened to allow fresh air to enter the first air duct 12, and when a first opening condition is satisfied, the first electric auxiliary heater 52 is turned on.

Obviously, in the first operation mode, the first fan assembly 4 operates, the airflow in the first air duct 12 flows under the driving action of the first fan assembly 4 to generate negative pressure at the fresh air inlet 12a, the outdoor air can flow into the first air duct 12 through the fresh air inlet 12a and finally flow out through the air outlet 12b, and at this time, the air conditioner 100 can be in the fresh air mode, that is, in the fresh air mode, the first air duct 12 can realize a fresh air function. When the first opening condition is met, the air conditioner 100 needs to generate more heat, and the first electric auxiliary heater 52 is opened at the moment, so that the heat exchange between the air flow in the first air duct 12 and the first electric auxiliary heater 52 is realized, the air outlet temperature of the first air duct 12 is effectively improved, the temperature of outdoor fresh air blown out from the air outlet 12b by the air conditioner 100 is ensured, and the influence on the indoor comfort caused by the excessively low temperature of the blown outdoor fresh air is avoided.

It will be appreciated that in the first mode of operation, the first electric auxiliary heater 52 may always remain switched off if the first switching condition is not always fulfilled.

Therefore, according to the control method of the air conditioner 100 in the embodiment of the present invention, the energy consumption of the air conditioner 100 is low, the aging rate of the connection circuit is slowed down, and the service life of the air conditioner 100 is conveniently ensured, and by setting the first operation mode of the air conditioner 100, the heating capacity of the air conditioner 100 is improved, which is beneficial to further saving the overall energy consumption of the air conditioner 100, slowing down the aging rate of the circuit, and ensuring the service life, and meanwhile, the fresh air blown out by the air conditioner 100 is conveniently ensured to have a proper temperature, so as to ensure the indoor comfort.

Alternatively, the condition for the air conditioner 100 to enter the first operation mode may be preset as: indoor temperature and indoor humidity all satisfy the default that the new trend was opened to guarantee that first mode of operation maintains indoor travelling comfort better.

In some embodiments, as shown in fig. 4 and 7, the first on condition is: the temperature of the fresh air at the fresh air inlet 12a is lower than a first preset value T1, that is, in the first operation mode, when the temperature of the fresh air at the fresh air inlet 12a is lower than a first preset value T1, the first electric auxiliary heater 52 is turned on to heat the air flow in the first air duct 12, so that the temperature of the outdoor fresh air introduced by the air conditioner 100 is ensured, and meanwhile, the timeliness of turning on the first electric auxiliary heater 52 is facilitated, so that the temperature of the blown outdoor fresh air is further ensured.

It is understood that the first opening condition is not limited thereto, for example, the first opening condition may also be that the temperature of the fresh air at other positions in the first air duct 12 (such as at the air outlet 12 b) is lower than the first preset value T1.

In some embodiments, as shown in fig. 4 and 7, in the first operation mode, when the first off condition is satisfied, the first electric auxiliary heat 52 is turned off, which is beneficial to saving energy consumption of the air conditioner 100. Wherein the first closing condition is: the temperature of the fresh air at the fresh air inlet 12a is higher than the second preset value T2, that is, in the first operation mode, after the first electric auxiliary heater 52 is turned on and operated for a period of time, if the temperature of the fresh air at the fresh air inlet 12a is higher than the second preset value T2, it indicates that the first electric auxiliary heater 52 does not need to be heated, and at this time, the first electric auxiliary heater 52 is kept turned off or is switched from the on state to the off state.

For example, in the example of fig. 4 and 7, in the first operation mode, the temperature of the fresh air at the fresh air inlet 12a can be detected in real time, when the detected temperature of the fresh air is lower than the first preset value T1, the first electric auxiliary heater 52 is turned on, and after the first electric auxiliary heater 52 is turned on, if the detected temperature of the fresh air is higher than the second preset value T2, the first electric auxiliary heater 52 is switched off. Of course, in the first operating mode, if the fresh air temperature detected in real time is always higher than the second preset value T2, the first electric auxiliary heater 52 is always kept turned off.

In some embodiments, in the first mode of operation, the indoor air inlet 12c is closed and the first heat exchanger 22 is deactivated. Obviously, in the first operation mode, the first heat exchanger 22 does not heat or cool the airflow in the first air duct 12, and the indoor air cannot flow into the first air duct 12 through the indoor air inlet 12 c. At this time, the first air duct 12 of the air conditioner 100 only realizes the fresh air function, so as to realize the circulation of air indoors and outdoors and ensure the indoor temperature.

In some embodiments, as shown in fig. 3 to 7, the air conditioner 100 further has a second operation mode in which the indoor air inlet 12c is opened to allow the indoor air to enter the first duct 12, the first heat exchanger 22 performs a heating operation, and the first electric auxiliary heater 52 is turned on when the second turn-on condition is satisfied.

Obviously, in the second operation mode, the first heat exchanger 22 performs heating operation, and at this time, the air conditioner 100 may be in the heating mode, that is, in the heating mode, the first air duct 12 may implement a heating function, so that the heating amount of the air conditioner 100 is effectively increased, and the heating performance of the air conditioner 100 is ensured; the airflow in the first air duct 12 flows under the driving action of the first fan assembly 4 to generate a negative pressure at the indoor air inlet 12c, so that the indoor air flows into the first air duct 12 through the indoor air inlet 12c, and the heat-exchanged airflow flows out through the air outlet 12 b. When the second opening condition is met, the air conditioner 100 needs to generate more heat, at the moment, the first electric auxiliary heater 52 is opened, so that the heat exchange between the air flow in the first air duct 12 and the first heat exchanger 22 and the heat exchange between the first electric auxiliary heater 52 and the first air duct 12 are realized, the air outlet temperature of the first air duct 12 is effectively improved, on the premise of ensuring the air outlet quantity of the air conditioner 100, the heat in the heating mode of the air conditioner 100 is improved, so that the air conditioner 100 can better meet the requirement, and because the first heat exchanger 22 is in heating operation, the energy consumption generated by the first electric auxiliary heater 52 is favorably reduced, so that the energy consumption is further saved.

Alternatively, in the second operation mode, the first air duct 12 may only implement the heating function, i.e. the fresh air inlet 12a is always closed, so as to further enrich the operation state of the air conditioner 100.

In some embodiments, as shown in fig. 3-7, the air conditioner 100 further has a third operation mode, in which the fresh air inlet 12a and the indoor air inlet 12c are both opened, so that both fresh air and indoor air enter the first air duct 12, the first heat exchanger 22 performs heating operation, and when the second opening condition is satisfied, the first electric auxiliary heater 52 is turned on.

Obviously, in a third operation mode, the first air duct 12 can simultaneously realize fresh air and heating functions, the airflow in the first air duct 12 flows under the driving action of the first fan assembly 4 to generate negative pressure at the fresh air inlet 12a and the indoor air inlet 12c, then the indoor air flows into the first air duct 12 through the indoor air inlet 12c, the fresh air flows into the first air duct 12 through the fresh air inlet 12a, and exchanges heat with the first heat exchanger 22, and the airflow after heat exchange flows out through the air outlet 11 b. When the second opening condition is met, the air conditioner 100 needs to generate more heat, and the first electric auxiliary heater 52 is opened at the moment, so that the heat exchange between the airflow in the first air duct 12 and the first heat exchanger 22 and the first electric auxiliary heater 52 is realized, the air outlet temperature of the first air duct 12 is effectively improved, and meanwhile, the air outlet quantity of the air conditioner 100 is larger, and the heat utilization rate of the first electric auxiliary heater 52 is favorably improved.

Alternatively, the air conditioner 100 has a second operation mode in which the indoor air inlet 12c is opened to allow indoor air to enter the first duct 12, the first heat exchanger 22 performs a heating operation, and the first electric supplementary heat 52 is turned on when a second turn-on condition is satisfied; in the third operation mode, the fresh air inlet 12a and the indoor air inlet 12c are both opened, so that both fresh air and indoor air enter the first air duct 12, the first heat exchanger 22 performs heating operation, and when the second opening condition is satisfied, the first electric auxiliary heater 52 is opened.

In other words, in the third operation mode, the control logic of the first electric auxiliary heater 52 is the same as the control logic of the first electric auxiliary heater 52 in the first operation mode, and as long as the first heat exchanger 22 performs the heating operation, the control logic of the first electric auxiliary heater 52 is preferentially performed based on the control logic of the air-conditioning heating operation, which facilitates simplification of the control logic of the air conditioner 100 and is more beneficial to maintaining the comfort of the indoor environment.

In some embodiments, as shown in fig. 4, the second turn-on condition is: the indoor temperature is lower than the first set temperature, the outdoor temperature is lower than the second set temperature, the temperature of the first heat exchanger 22 is lower than the third set temperature, and the difference between the set target temperature of the air conditioner 100 and the indoor temperature is greater than the fourth set temperature. The first set temperature is higher than the second set temperature, and the first set temperature is lower than the third set temperature. Therefore, the timeliness of the first electric auxiliary heater 52 is guaranteed, energy saving of the air conditioner 100 is achieved, and safe operation of the air conditioner 100 is guaranteed.

Wherein, the fourth setting temperature can be specifically set according to actual conditions.

In some embodiments, as shown in fig. 1 and fig. 2, the air conditioner 100 further includes a second fan assembly 3, the casing 1 defines a second air duct 11, the casing 1 is formed with an air inlet 11a and an air outlet 11b communicated with the second air duct 11, the heat exchanger assembly 2 further includes a second heat exchanger 21, the electric auxiliary heating assembly 5 further includes a second electric auxiliary heater 51, and the second heat exchanger 21, the second fan assembly 3 and the second electric auxiliary heater 51 are all disposed in the second air duct 11, so that an air flow in the second air duct 11 can exchange heat with the second heat exchanger 21 and/or the second electric auxiliary heater 51 to ensure a cooling/heating capability of the air conditioner 100, and the second air duct 11 can be used as a heat exchange air duct of the air conditioner 100.

The second air duct 11 and the first air duct 12 are separately arranged, and the second air duct 11 and the first air duct 12 are mutually independent and do not interfere with each other, so that the heat exchange efficiency of the air conditioner 100 is ensured, and the first air duct 12 and the second air duct 11 can realize multiple air outlet modes of the air conditioner 100 in an independent and combined mode, for example, the second air duct 11 realizes air outlet through the air outlet 11b and the first air duct 12 does not realize air outlet, or the second air duct 11 does not realize air outlet and the first air duct 12 realizes air outlet through the air outlet 12b, or the second air duct 11 realizes air outlet through the air outlet 11b and the first air duct 12 realizes air outlet through the air outlet 12b, so that the air outlet modes of the air conditioner 100 are enriched, so that the air conditioner 100 has different air outlet effects, the operation modes of the air conditioner 100 are further enriched, and the differentiation requirements of different.

As shown in fig. 5 to 7, in the first operation mode, when the second fan assembly 3 is turned off, the airflow in the second air duct 11 does not flow, so that the second air duct 11 does not discharge air, and the whole air conditioner 100 only realizes a fresh air function.

Optionally, in the first operation mode, the fresh air inlet 12a is opened, the indoor air inlet 12c is closed, the first fan assembly 4 is operated, the second fan assembly 3 is closed, and both the first heat exchanger 22 and the second heat exchanger 21 stop operating, that is, the first heat exchanger 22 does not heat or cool the air flow in the first air duct 12, and the second heat exchanger 21 does not heat or cool the air flow in the second air duct 11. When the first turn-on condition is satisfied, the first electric assist heat 52 is turned on.

It will be appreciated that in the first operating mode, the second electric auxiliary heat 51 may always remain switched off, and if the first switching condition is not always satisfied, the first electric auxiliary heat 52 may always remain switched off.

In some embodiments, as shown in fig. 5 to 7, the air conditioner 100 further has a second operation mode, in which both the indoor air inlet 12c and the air inlet 11a are opened to allow the indoor air to enter the first air duct 12 and the second air duct 11, respectively, the heat exchanger assembly 2 performs a heating operation, both the first heat exchanger 22 and the second heat exchanger 21 may perform a heating operation, and when the second opening condition is satisfied, both the first electric auxiliary heater 52 and the second electric auxiliary heater 51 are turned on.

Obviously, in the second operation mode, the air conditioner 100 may be in a heating mode, that is, in the heating mode, both the first air duct 12 and the second air duct 11 implement a heating function, so that the heating capacity of the air conditioner 100 is effectively improved, and the heating performance of the air conditioner 100 is ensured. When the second opening condition is met, the air conditioner 100 needs to generate more heat, at this time, the first electric auxiliary heater 52 and the second electric auxiliary heater 51 are both opened, so that the heat exchange between the air flow in the first air duct 12 and the first heat exchanger 22 and the first electric auxiliary heater 52, and the heat exchange between the air flow in the second air duct 11 and the second heat exchanger 21 and the second electric auxiliary heater 51 are realized, the air outlet temperature of the first air duct 12 and the second air duct 11 is effectively increased, on the premise that the air outlet quantity of the air conditioner 100 is ensured, the heat in the heating mode of the air conditioner 100 is increased, so that the air conditioner 100 can better meet the requirement, and because the first heat exchanger 22 and the second heat exchanger 21 are in heating operation, the reduction of the energy consumption generated by the electric auxiliary heater assembly 5 is facilitated, and the energy consumption is further saved.

In addition, for in some technologies, set up isolated heat transfer wind channel and new wind channel in the air conditioner, new wind channel does not have the heat transfer function, when the air conditioner heats the operation, only heat transfer wind channel air-out, and air conditioner 100 in this application under the second operation mode, first wind channel 12 and second wind channel 11 can blow off hot-blast simultaneously, have promoted air conditioner 100's heating ability.

Alternatively, in the second operation mode, the second air duct 11 realizes a heating function, and the first air duct 12 may realize only the heating function, that is, the fresh air inlet 12a is always closed.

In some embodiments, as shown in fig. 5 to 7, the air conditioner 100 further has a third operation mode, in which the fresh air inlet 12a, the indoor air inlet 12c and the air inlet 11a are all opened, so that fresh air enters the first air duct 12, indoor air enters the first air duct 12 and the second air duct 11, respectively, the heat exchanger assembly 2 performs heating operation, the first heat exchanger 22 and the second heat exchanger 21 can both perform heating operation, and when the second opening condition is satisfied, the first electric auxiliary heater 52 and the second electric auxiliary heater 51 are both opened.

Obviously, in the third operation mode, the first air duct 12 can simultaneously realize the fresh air function and the heating function, and the second air duct 11 can realize the heating function. When the second opening condition is met, the air conditioner 100 needs to generate more heat, at the moment, the first electric auxiliary heater 52 and the second electric auxiliary heater 51 are both opened, so that heat exchange between the air flow in the first air duct 12 and the first heat exchanger 22 and the first electric auxiliary heater 52 and heat exchange between the air flow in the second air duct 11 and the second heat exchanger 21 and the second electric auxiliary heater 51 are realized, the air outlet temperatures of the first air duct 12 and the second air duct 11 are effectively increased, meanwhile, the air outlet quantity of the air conditioner 100 is larger, and the heat utilization rate of the first electric auxiliary heater 52 is favorably increased.

Optionally, in the second operation mode and the third operation mode, when the electrical auxiliary heat turn-off condition is satisfied, the heat generated by the air conditioner 100 may satisfy the requirement, and at this time, both the first electrical auxiliary heat 52 and the second electrical auxiliary heat 51 are turned off, so that the energy consumption of the air conditioner 100 is saved, and the cost is reduced. Wherein, the electric auxiliary heat closing condition can be as follows: the indoor temperature reaches the preset temperature; but is not limited thereto.

Alternatively, in the second operation mode and the third operation mode, when the second turn-on condition is satisfied, the first electric auxiliary heater 52 and the second electric auxiliary heater 51 may be turned on simultaneously, and when the electric auxiliary heater assembly 5 needs to be turned off, for example, when the electric auxiliary heater turn-off condition is satisfied, the first electric auxiliary heater 52 and the second electric auxiliary heater 51 may be turned off simultaneously, so that the operating states of the first electric auxiliary heater 52 and the second electric auxiliary heater 51 are synchronized, which facilitates the control of the electric auxiliary heater assembly 5 and simplifies the control of the electric auxiliary heater assembly 5.

In some embodiments, the second heat exchanger 21 and the first heat exchanger 22 are arranged in series or in parallel. For example, when the second heat exchanger 21 and the first heat exchanger 22 are arranged in series, the refrigerant in the refrigerant circulation system of the air conditioner 100 flows through the second heat exchanger 21 and the first heat exchanger 22 in sequence, or flows through the first heat exchanger 22 and the first heat exchanger 22 in sequence; when the second heat exchanger 21 and the first heat exchanger 22 are arranged in parallel, the refrigerant inlet of the second heat exchanger 21 is connected to the refrigerant inlet of the first heat exchanger 22, and the refrigerant outlet of the second heat exchanger 21 is connected to the refrigerant outlet of the first heat exchanger 22. Therefore, the arrangement between the second heat exchanger 21 and the first heat exchanger 22 is flexible, and the structural diversity of the air conditioner 100 is enriched.

For example, when the second heat exchanger 21 and the first heat exchanger 22 are disposed in series, the second heat exchanger 21 and the first heat exchanger 22 are in common piping, and at the same time, the state of the second heat exchanger 21 and the state of the first heat exchanger 22 are the same, if the air conditioner 100 performs cooling, heating, blowing, dehumidifying, or automatic functions, the states of the second heat exchanger 21 and the first heat exchanger 22 may be kept the same; for example, the air conditioner 100 has a first operation mode, in the first operation mode, the fresh air inlet 12a is opened, the indoor air inlet 12c is closed, the first fan assembly 4 is opened, the second fan assembly 3 is closed, and both the second heat exchanger 21 and the first heat exchanger 22 stop operating, when the temperature of the fresh air at the fresh air inlet 12a is lower than a first preset value T1, the first electric auxiliary heater 52 is opened, and after the first electric auxiliary heater 52 is opened and operates for a period of time, if the temperature of the fresh air at the fresh air inlet 12a is higher than a second preset value T2, the first electric auxiliary heater 52 is closed; the air conditioner 100 has a second operation mode in which the fresh air inlet 12a is closed, the indoor air inlet 12c is opened, the second fan assembly 3 and the first fan assembly 4 are both opened, and the second heat exchanger 21 and the first heat exchanger 22 are both in heating operation, and when a second opening condition is satisfied, the second electric auxiliary heater 51 and the first electric auxiliary heater 52 are both opened.

At this time, the air conditioner 100 may further have a third operation mode in which the fresh air inlet 12a, the indoor air inlet 12c, and the air intake 11a are all opened, the second fan assembly 3 and the first fan assembly 4 are both opened, and the first heat exchanger 22 and the second heat exchanger 21 are both in heating operation, and when the second opening condition is satisfied, the first electric auxiliary heater 52 and the second electric auxiliary heater 51 are both opened.

For example, when the second heat exchanger 21 and the first heat exchanger 22 are arranged in parallel, the first heat exchanger 22 and the second heat exchanger 21 are separated in pipeline, and the first heat exchanger 22 and the second heat exchanger 21 can be controlled independently, so that the state of the first heat exchanger 22 and the state of the second heat exchanger 21 can be the same or different at the same time; the air conditioner 100 may also have a first operation mode, a second operation mode, and a third operation mode at this time.

In some embodiments, as shown in fig. 6 and 7, when the second heat exchanger 21 and the first heat exchanger 22 are arranged in parallel, the air conditioner 100 further has a fourth operation mode, in which the fresh air inlet 12a is opened to allow fresh air to enter the first air duct 12, the second heat exchanger 21 is in non-heating operation, and when the third opening condition is satisfied, the first electric auxiliary heater 52 is turned on.

Obviously, in the fourth operation mode, the second heat exchanger 21 is not in heating operation, the airflow in the second air duct 11 is driven by the second fan assembly 3 to generate negative pressure at the air inlet 11a, and the indoor air flows into the second air duct 11 through the air inlet 11a and finally flows out through the air outlet 11 b; the air flow in the first air duct 12 flows under the driving action of the first fan assembly 4, the outdoor air flows into the first air duct 12 through the fresh air inlet 12a and finally flows out through the air outlet 12b, at this time, the portion of the air conditioner 100 corresponding to the second air duct 11 can be in a non-heating mode, such as a cooling mode, a dehumidification mode, an air supply mode, or an automatic mode, and the portion of the air conditioner 100 corresponding to the first air duct 12 can be in a fresh air mode, so that the whole air conditioner 100 can simultaneously perform a non-heating function and a fresh air function. When the third opening condition is satisfied, it indicates that the air conditioner 100 needs to generate more heat, however, since the second heat exchanger 21 is not in heating operation, the second electric auxiliary heater 51 cannot be opened, and at this time, the first electric auxiliary heater 52 is opened to provide the required heat by raising the temperature of the blown outdoor fresh air, the control logic is simple, and there is no conflict with the operation of the heat exchanger assembly 2.

In the description of the present application, "the second heat exchanger 21 is not in the heating operation" should be broadly understood and may include the second heat exchanger 21 in the cooling operation, the second heat exchanger 21 in the stop operation, and the second heat exchanger 21 in the automatic operation. Wherein, the cooling operation of the second heat exchanger 21 may correspond to a cooling mode or a dehumidifying mode of the air conditioner 100; when the second heat exchanger 21 stops operating, if the second fan assembly 3 is turned on, the air supply mode of the air conditioner 100 may be corresponded; the automatic operation of the second heat exchanger 21 may correspond to an automatic mode of the air conditioner 100, which is well known to those skilled in the art and will not be described herein.

In some implementations, in the fourth operation mode, the indoor air inlet 12c is closed, the indoor air cannot enter the first air duct 12, the first air duct 12 only implements the fresh air function, and the first heat exchanger 22 stops operating, so that the first heat exchanger 22 does not heat or cool the air flow in the first air duct 12. In the fourth operating mode, the second electric auxiliary heater 51 can be switched off at all times.

In some embodiments, as shown in fig. 7, the third open condition is: the temperature of the fresh air at the fresh air inlet 12a is lower than the third preset value T3, that is, in the fourth operation mode, when the temperature of the fresh air at the fresh air inlet 12a is lower than the third preset value T3, the first electric auxiliary heater 52 is turned on to heat the airflow in the first air duct 12, so as to ensure the temperature of the outdoor fresh air introduced by the air conditioner 100, and to facilitate ensuring the timeliness of turning on the first electric auxiliary heater 52.

It is to be understood that the third opening condition is not limited thereto, for example, the third opening condition may also be that the temperature of the fresh air at other positions in the first air duct 12 (such as at the air outlet 12 b) is lower than the third preset value T3.

In some embodiments, as shown in fig. 7, the first turn-on condition is: the temperature of the fresh air at the fresh air inlet 12a is lower than a first preset value T1, and the third opening condition is as follows: the temperature of the fresh air at the fresh air inlet 12a is lower than the third preset value T3, and the first preset value T1 is greater than the third preset value T3. Because when the air conditioner 100 executes the non-heating function and the fresh air function simultaneously, the temperature in the air conditioner 100 is lower, condensation in the air conditioner 100 is easier, and the third preset value T3 is set to be smaller than the first preset value T1, so that the fresh air temperature corresponding to the opening condition of the first electric auxiliary heater 52 in the fourth operation mode is lower than the temperature corresponding to the opening condition in the first operation mode, the temperature in the air conditioner 100 is increased, the problem that the air conditioner 100 is prone to condensation is solved, and the maintenance of the air conditioner 100 is facilitated.

In some embodiments, in the fourth operation mode, when the second off condition is satisfied, the first electric auxiliary heater 52 is turned off, which is beneficial to saving energy consumption and reducing cost of the air conditioner 100. Wherein the second shut-off condition is: the temperature of the fresh air at the fresh air inlet 12a is higher than the fourth preset value T4, that is, in the fourth operation mode, after the first electric auxiliary heater 52 is turned on and operated for a period of time, if the temperature of the fresh air at the fresh air inlet 12a is higher than the fourth preset value T4, it indicates that the first electric auxiliary heater 52 does not need to be heated, and at this time, the first electric auxiliary heater 52 is kept turned off or is switched from the on state to the off state.

For example, in the example of fig. 7, in the fourth operation mode, the temperature of the fresh air at the fresh air inlet 12a can be detected in real time, when the detected temperature of the fresh air is lower than the third preset value T3, the first electric auxiliary heater 52 is turned on, and after the first electric auxiliary heater 52 is turned on, if the detected temperature of the fresh air is higher than the fourth preset value T4, the first electric auxiliary heater 52 is switched off. Of course, in the fourth operating mode, if the fresh air temperature detected in real time is always higher than the fourth preset value T4, the first electric auxiliary heater 52 is always kept turned off.

In some embodiments, as shown in fig. 7, in the first operating mode, when the first turn-off condition is satisfied, the first electric auxiliary heater 52 is turned off, and in the fourth operating mode, when the second turn-off condition is satisfied, the first electric auxiliary heater 52 is turned off. Wherein the first closing condition is: the temperature of the fresh air at the fresh air inlet 12a is higher than a second preset value T2, and the second closing condition is as follows: the temperature of the fresh air at the fresh air inlet 12a is higher than the fourth preset value T4, and the second preset value T2 is smaller than the fourth preset value T4. Because the air conditioner 100 executes the non-heating function and the fresh air function simultaneously, the temperature in the air conditioner 100 is lower, condensation in the air conditioner 100 is easier, and the fourth preset value T4 is set to be greater than the second preset value T2, so that the fresh air temperature corresponding to the closing condition of the first electric auxiliary heater 52 in the fourth operation mode is higher than the temperature corresponding to the closing condition in the first operation mode, the temperature in the air conditioner 100 is ensured to be higher for a long time, and the problem that condensation is easy to occur in the air conditioner 100 is solved.

In some embodiments, the opening and closing of the fresh air inlet 12a and the indoor air inlet 12c may be achieved by providing a switch door or a switch. For example, the fresh air inlet 12a and the indoor air inlet 12c are respectively provided with a switch door, the switch door at the fresh air inlet 12a can open or close the fresh air inlet 12a, and the switch door at the indoor air inlet 12c can open or close the indoor air inlet 12c, so the states of the fresh air inlet 12a and the indoor air inlet 12c may include the following conditions: 1. the fresh air inlet 12a is opened, and the indoor air inlet 12c is opened; 2. the fresh air inlet 12a is opened, and the indoor air inlet 12c is closed; 3. the fresh air inlet 12a is closed, and the indoor air inlet 12c is opened; 4. the fresh air inlet 12a is closed and the indoor air inlet 12c is closed. For another example, the casing 1 may be provided with a switch, the switch may have a first state and a second state to switch on the fresh air inlet 12a and the indoor air inlet 12c, when the switch is in the first state, the fresh air inlet 12a is closed, the indoor air inlet 12c is opened, and when the switch is in the second state, the fresh air inlet 12a is opened, and the indoor air inlet 12c is closed; of course, the switch may have a third state, and when the switch is in the third state, both the fresh air inlet 12a and the indoor air inlet 12c are open.

When the indoor air inlets 12c are also formed at the left and right sides of the cabinet 1, the indoor air inlets 12c at the left and right sides of the cabinet 1 are located downstream of the filter members 61.
