In the description of the present application, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; the specific meaning of the above terms in the present application can be understood in a specific case by those of ordinary skill in the art.

As described in the background, some air conditioners currently provide a reheat dehumidification mode to meet consumer demand for dehumidification. However, according to the related art air conditioner control method, after a user instructs the air conditioner to enter the reheat dehumidification mode, the air conditioner operates the cooling mode to lower the indoor temperature to a target temperature set by the user, and then operates the reheat dehumidification mode. Since the indoor temperature is further reduced when the air conditioner operates in the reheat dehumidification mode, the indoor temperature is lower than the target temperature by the above control method, which affects user comfort and increases energy consumption.

In view of this, an embodiment of the present application provides a method for controlling an air conditioner, which specifically includes: after receiving an instruction of a user for indicating the air conditioner to enter a reheating and dehumidifying mode, acquiring an indoor temperature and a target temperature; and controlling the air conditioner to enter a reheating and dehumidifying mode under the condition that the indoor temperature is less than or equal to the sum of the first target temperature and a first preset temperature and the first indoor temperature is greater than the first target temperature.

Based on the technical scheme that this application embodiment provided, the air conditioner can get into the dehumidification mode of reheating before the indoor temperature has not reached the target temperature yet to avoid the air conditioner operation dehumidification mode of reheating to lead to the indoor temperature too being less than the target temperature, be favorable to guaranteeing user's travelling comfort, and save the energy consumption of air conditioner.

The control method of the air conditioner provided by the embodiment of the application can be applied to the air conditioner with a reheating and dehumidifying mode, such as the air conditioner shown in fig. 1 or 2. The embodiment of the present application does not limit the structure, model, and the like of the air conditioner having the reheat dehumidification mode.

For example, fig. 1 shows a schematic structure of an air conditioner having a reheat dehumidification mode. As shown in fig. 1, the air conditioner includes an indoor fan 1, a first indoor heat exchanger 2, a second indoor heat exchanger 3, a dehumidification solenoid valve 4, an expansion valve 5, an outdoor heat exchanger 6, an outdoor fan 7, a four-way valve 8, a compressor 9, and a gas-liquid separator 10.

The first indoor heat exchanger 2 and the second indoor heat exchanger 3 are arranged in the front and back direction along the air outlet direction of the indoor fan 1. With the operation of the indoor fan 1, an air flow formed by the indoor air can pass through the first indoor heat exchanger 2 and the second indoor heat exchanger 3 in sequence.

In the reheat dehumidification mode of the air conditioner, the first indoor heat exchanger 2 absorbs heat for the evaporator, and the second indoor heat exchanger 3 releases heat for the condenser. After being sucked by the indoor fan, the indoor air is firstly cooled and dehumidified by the first indoor heat exchanger 2 and then heated by the second indoor heat exchanger 3, so that the reheating and dehumidifying effects are achieved.

However, the air conditioner shown in fig. 1 has the following drawbacks: when the air conditioner is in a heating mode, the first indoor heat exchanger 2 and the second indoor heat exchanger 3 both function as condensers. At this time, the heat exchange temperature of the indoor air first rises at the first indoor heat exchanger 2, and the air after the temperature rise is again raised by the second indoor heat exchanger 3. Since the refrigerant temperatures of the first indoor heat exchanger 2 and the second indoor heat exchanger 3 are the same, the initial temperature of the air at the first indoor heat exchanger 2 is lower than the initial temperature at the second indoor heat exchanger 3. Therefore, the temperature rise difference of the air in heat exchange when passing through the first indoor heat exchanger 2 is larger than that of the air in heat exchange when passing through the second indoor heat exchanger 3. Thus, the refrigerant temperature change of the second indoor heat exchanger 3 is small, and the degree of supercooling of the refrigerant flowing through the indoor unit is reduced, thereby reducing the capacity. And, the first indoor heat exchanger 2 and the second indoor heat exchanger 3 are arranged in front and at the back, so that the wind resistance of the indoor unit is large, and the energy consumption of the air conditioner is increased accordingly.

In this regard, the embodiment of the present application provides another air conditioner, and the structure of the air conditioner may be as shown in fig. 2. The air conditioner shown in fig. 2 is different from the air conditioner shown in fig. 1 in that: in the air conditioner shown in fig. 2, the first indoor heat exchanger 2 and the second indoor heat exchanger 3 are sequentially arranged in a direction perpendicular to the air outlet direction of the indoor fan 1.

In this way, a part of air blown by the indoor fan 1 passes through the first indoor heat exchanger 2, and the other part of air passes through the second indoor heat exchanger 3, so that the wind resistance of the indoor unit is reduced, and the energy consumption of the system is reduced.

Alternatively, in the air conditioner shown in fig. 2, a V-shape or other shape may be formed between the first indoor heat exchanger 2 and the second indoor heat exchanger 3, which is not limited.

Fig. 3(a) is a schematic view illustrating a refrigerant flow direction of the air conditioner shown in fig. 2 in a cooling mode or a reheating and dehumidifying mode. Fig. 3(b) is a schematic diagram of a refrigerant flow direction of the air conditioner shown in fig. 2 in a cooling mode.

In the cooling mode of the air conditioner shown in fig. 2, the four-way valve 8 is in the first state, that is, the d end and the c end of the four-way valve 8 are connected, the e end and the s end are connected, and the dehumidification solenoid valve 4 is in the open state, at this time, the outdoor heat exchanger 6 serves as a condenser, and both the first indoor heat exchanger 2 and the second indoor heat exchanger 3 of the indoor unit serve as evaporators. The refrigerant in the compressor 9 flows into the outdoor heat exchanger 6 through the d-side and c-side of the four-way valve 8, releases heat in the outdoor heat exchanger 6, flows out of the outdoor unit through the expansion valve 5, and flows into the indoor unit. The refrigerant flowing into the indoor unit sequentially passes through the first indoor heat exchanger 2, the dehumidification solenoid valve 4 and the second indoor heat exchanger 3 of the indoor unit, at the moment, the dehumidification solenoid valve 4 is in an open state, the first indoor heat exchanger 2 and the second indoor heat exchanger 3 of the indoor unit are both used as evaporators, and the refrigerant absorbs heat at the first indoor heat exchanger 2 and the second indoor heat exchanger 3 of the indoor unit. Air blown out by the indoor fan 1 passes through the first indoor heat exchanger 2 and the second indoor heat exchanger 3 of the indoor unit, and heat exchange occurs between the first indoor heat exchanger 2 and the second indoor heat exchanger 3 due to heat absorption of a refrigerant in the process, so that the temperature of the air is reduced, and the indoor temperature is further reduced. Then, the refrigerant in the indoor unit flows into the gas-liquid separator 10 through the e end and the s end of the four-way valve 8, and further flows back to the compressor 9, so that a refrigeration cycle is formed.

In the reheating and dehumidifying mode of the air conditioner shown in fig. 2, the four-way valve 8 is in the first state, that is, the d end and the c end of the four-way valve 8 are connected, and the e end and the s end are connected, and the dehumidifying solenoid valve 4 is in the closed state, at this time, the outdoor heat exchanger 6 serves as a condenser, the first indoor heat exchanger 2 of the indoor unit serves as a condenser, and the second indoor heat exchanger 3 serves as an evaporator. The refrigerant flow direction of the system in the air conditioning system in the reheat dehumidification mode is the same as that of the refrigeration cycle, and the refrigerant in the indoor unit releases heat when flowing through the first indoor heat exchanger 2 and absorbs heat when flowing through the second indoor heat exchanger 3. Among the air blown by the indoor fan 1, a part of the air is heated when passing through the first indoor heat exchanger 2, and the other part of the air is cooled and dehumidified when passing through the second indoor heat exchanger 3. After the two portions of air are mixed, the humidity of the indoor environment is reduced without a drop in temperature.

In the heating mode of the air conditioner shown in fig. 2, the four-way valve 8 is in the second state, that is, the d end and the e end of the four-way valve are connected, the c end and the s end are connected, and the dehumidification solenoid valve 4 is in the open state, at this time, the outdoor heat exchanger 6 serves as an evaporator, and both the first indoor heat exchanger 2 and the second indoor heat exchanger 3 of the indoor unit serve as condensers. The refrigerant in the compressor 9 flows into the indoor unit through the d end and the e end of the four-way valve 8, sequentially passes through the second indoor heat exchanger 3, the dehumidification solenoid valve 4 and the first indoor heat exchanger 2 of the indoor unit, at this time, the dehumidification solenoid valve 4 is in an open state, both the first indoor heat exchanger 2 and the second indoor heat exchanger 3 of the indoor unit are used as condensers, and the refrigerant releases heat at the first indoor heat exchanger 2 and the second indoor heat exchanger 3 of the indoor unit. Indoor air is sucked by the indoor fan 1 and passes through the second indoor heat exchanger 3 and the first indoor heat exchanger 2 of the indoor unit, and heat exchange is carried out on the air at the second indoor heat exchanger 3 and the first indoor heat exchanger 2 due to heat release of the refrigerant in the process, so that the indoor temperature is increased along with the heat exchange. After flowing out of the first indoor heat exchanger 2, the refrigerant enters the outdoor heat exchanger 6 through the solenoid valve 5, absorbs heat at the outdoor heat exchanger 6, and then flows into the gas-liquid separator 10 through the c end and the s end of the four-way valve 8, and further flows back to the compressor 9, so that a heating cycle is formed.

The embodiments provided in the present application will be described in detail below with reference to the accompanying drawings.

As shown in fig. 4, an embodiment of the present application provides a control method of an air conditioner, including the following steps:

It will be appreciated that the conditions are set for the purpose of: under the condition that the indoor humidity is high, the air conditioner is controlled to enter a reheating dehumidification mode. In other words, when the indoor humidity is low, the air conditioner is not controlled to enter the reheating and dehumidifying mode, so that the energy consumption of the air conditioner is saved.

In the embodiment of the present application, the first preset humidity is preset. The first preset humidity may be determined through experiments, computer simulation, and the like, which are not limited thereto.

Based on the embodiment shown in fig. 4, the air conditioner may enter the reheating dehumidification mode before the indoor temperature reaches the target temperature, so as to avoid that the indoor temperature is too lower than the target temperature due to the reheating dehumidification mode in which the air conditioner operates, which is beneficial to ensuring the comfort of the user and saving the energy consumption of the air conditioner.

As shown in fig. 8(b), at time t1, the air conditioner switches from the cooling mode to the reheat dehumidification mode. After the air conditioner enters the reheating and dehumidifying mode, the indoor humidity is continuously reduced, so that the indoor humidity is close to Hs-dHs 1.

Alternatively, the process of the air conditioner entering the reheat dehumidification mode after the start-up may include a start-up stage, an action guarantee stage, an initial control stage, and a general control stage.

The process of the air conditioner entering the reheat dehumidification mode after being started will be described in detail with reference to fig. 9.

1. Temperature range determination phase

After the air conditioner is started, an instruction of a user for instructing the air conditioner to enter a reheating and dehumidifying mode is received. In response to a user instruction to enter the reheat dehumidification mode, the air conditioner enters a temperature range determination stage. In the temperature range determining stage, the compressor 9 and the outdoor fan 7 of the air conditioner are stopped, the expansion valve 5 is in a closed state, the dehumidification solenoid valve 4 is in an open state, and the indoor fan 1 is operated at an ultra-low speed.

After the target temperature and the target humidity are obtained, the air conditioner enters an action guarantee stage.

2. Action guarantee phase

In the action guarantee stage, the air conditioner adjusts the four-way valve to be in the first state, namely d end and c end connection, e end and s end connection of the four-way valve 8, the aperture of the expansion valve 5 is the initial aperture that is preset, and the dehumidification solenoid valve 4 is in the open state to make the refrigerant in the air conditioner can carry out the reheat dehumidification cycle.

The outdoor fan 7 is operated at a first rotation speed Va1 of the outdoor fan 7. Wherein Va1 is determined according to the outdoor temperature.

The indoor fan 1 starts to operate at the first rotational speed Vb1 of the indoor fan. Wherein, Vb1 is determined according to the windshield preset by the user.

The action assurance phase may be divided into two time periods. During the first period of time, the compressor 9 is stopped. During the second period of time, the compressor 9 starts to operate at the first rotational speed Vc1 of the compressor 9.

3. Initial control phase

In the initial control phase, the rotation speed of the compressor 9 is switched from Vc1 to the second rotation speed Vc2 of the compressor 9. The rotation speed of the outdoor fan 7 is maintained at Va 1. The rotation speed of the indoor fan 1 is maintained at Vb 1. During a later period of time of the initial control phase, i.e. during the third period of time in fig. 9, the expansion valve is in a fully open state (i.e. the opening degree of the expansion valve 5 is at a maximum value), and the dehumidification solenoid valve is switched to a closed state. In this case, the air conditioner really realizes the function of reheating and dehumidifying.

4. General control phase

In the normal control stage, the expansion valve is in the fully open state, the dehumidification solenoid valve is in the closed state, and the rotation speed of the indoor fan 1 is maintained at Vb 1.

In addition, in the normal control phase, on the one hand, the indoor temperature is precisely controlled to be close to the target temperature and the indoor humidity is precisely controlled to be close to the target humidity by adjusting the rotating speed of the compressor 9. On the other hand, the rotating speed of the outdoor fan 7 is adjusted to accurately control the indoor temperature to be close to the target temperature.

As shown in fig. 10, the method of adjusting the rotation speed of the compressor 9 may include the steps of:

s201, acquiring the target temperature and the target humidity in the current period.

S202, determining the target evaporation temperature in the reheating and dehumidifying mode according to the target temperature and the target humidity in the current period.

The evaporation temperature of the refrigerant is the evaporation critical temperature at which the refrigerant changes from liquid to gas in the evaporator. In the reheat dehumidification mode of the air conditioner, the temperature of the indoor heat exchanger (for example, the first indoor heat exchanger 2) as the evaporator is usually detected as the measured evaporation temperature of the refrigerant. The above target evaporation temperature is a temperature that the indoor heat exchanger (e.g., the first indoor heat exchanger 2) as the evaporator needs to reach.

Alternatively, the target evaporation temperature may be calculated according to the following formula (1):

Te0＝A×Ts-B-dTe (1)

where Te0 denotes a target evaporation temperature, Ts denotes the target temperature, dTe is a third preset temperature, and a and B are constants determined according to the target humidity.

Alternatively, the above formula (1) may be a formula fitted through a psychrometric chart. It should be understood that the different target humidities, a and B, are determined to be different constants.

For example, when the target humidity Hs is 40%, Te0 is a1 × Ts-B1-dTe;

when the target humidity Hs is 50%, Te0 is A2 × Ts-B2-dTe;

when the target humidity Hs is 60%, Te0 is A3 × Ts-B3-dTe.

A1, a2, A3, B1, B2, B3 are all constants.

And S203, adjusting the rotating speed of the compressor according to the target evaporation temperature.

It should be appreciated that the speed of the compressor may be adjusted periodically.

For example, the rotation speed of the compressor for the current cycle may be determined according to the following equation (2):

Ft(n)＝Ft(n-1)+ΔF (2)

where ft (n) represents the rotation speed of the compressor in the current cycle. Ft (n-1) represents the rotational speed of the compressor in the previous cycle. Δ F represents a rotational speed adjustment value of the compressor.

Optionally, in order to ensure the normal operation of the compressor, the rotation speed of the compressor is represented by Ft, Ft is greater than or equal to Ft and is less than or equal to Ftmax, Ftmin represents the minimum value of the preset rotation speed of the compressor, and Ftmax represents the maximum value of the preset rotation speed of the compressor. Therefore, if ft (n) calculated according to the formula (2) is greater than Ftmax, the compressor is controlled to operate at Ftmax; and if Ft (n) is less than Ftmin, controlling the compressor to operate at Ftmin.

Alternatively, Δ F may be determined according to the following equation (3):

△F＝Kp×[ePs(n)-ePs(n-1)]+Ki×ePs(n) (3)

wherein eps (n) ═ Te (n) — Te 0. Te (n) represents the actual temperature of the first indoor heat exchanger 2 in the current cycle.

ePs (n-1) ═ Te (n-1) -Te 0. Te (n-1) represents the actual temperature of the first indoor heat exchanger 2 in the previous cycle.

In addition, the default setting ePs (0) is ePs (1). Kp and Ki are both constants.

Optionally, in order to ensure the normal operation of the compressor, Δ Fmin is less than or equal to Δ F is less than or equal to Δ Fmax, Δ Fmin represents the minimum value of the rotating speed adjusting value of the compressor, and Δ Fmax represents the maximum value of the rotating speed adjusting value of the compressor. Therefore, if Δ F calculated according to formula (3) is larger than Δ Fmax, Ft (n) ═ Ft (n-1) + Δ Fmax is determined; if Δ F calculated according to formula (3) is smaller than Δ Fmin, Ft (n) ═ Ft (n-1) + Δfmin is determined.

Based on the embodiment shown in fig. 10, a reasonable target evaporation temperature is determined according to the target temperature and the target humidity, and the temperature of the indoor heat exchanger serving as the evaporator can reach the target evaporation temperature by continuously adjusting the rotating speed of the compressor, so that the indoor temperature and the indoor humidity can be accurately controlled.

As shown in fig. 11, the method for adjusting the rotation speed of the outdoor fan 7 may include the steps of:

s301, acquiring the target temperature and the indoor temperature of the current period, and the target temperature and the indoor temperature of the previous period.

S302, determining a rotating speed adjusting value of the outdoor fan according to the target temperature and the indoor temperature of the current period and the target temperature and the indoor temperature of the previous period.

As a possible implementation manner, a temperature change value is determined according to a target temperature and an indoor temperature in a current period, and a target temperature and an indoor temperature in a previous period; and then, determining a rotating speed adjusting value of the outdoor fan according to the temperature change value.

Alternatively, the temperature change value may be determined according to the following equation (4):

△Nfo＝Kfp×[eTi(n)-eTi(n-1)]+Kfi×eTi(n) (4)

where Δ Nfo represents a temperature change value. Kfp and Kfi are both constants.

eti (n) ═ ti (n) — ts (n). Where ti (n) represents the indoor temperature of the current cycle, and ts (n) represents the target temperature of the current cycle.

eTi (n-1) ═ Ti (n-1) -Ts (n-1). Wherein Ti (n-1) represents the indoor temperature of the previous cycle, and Ts (n-1) represents the target temperature of the previous cycle.

In addition, eTi (0) is default to eTi (1).

The initial value of the outdoor fan is a first rotation speed Va1 of the outdoor fan 7.

Alternatively, the speed adjustment value of the outdoor fan may be expressed in speed steps. For example, table 1 shows the correspondence between the rotation speed step and the temperature change value.

TABLE 1

STEP size of rotation Speed (STEP)	Temperature Change value (. degree. C.)
		+5STEP	+100＜△Nfo
+3STEP	+50＜△Nfo≤+100
		+2STEP	+20＜△Nfo≤+50
+1STEP	+5＜△Nfo≤+20
		0 (i.e., unchanged)	-5＜△Nfo≤+5
-1STEP	-20＜△Nfo≤-5
		-2STEP	-50＜△Nfo≤-20
-3STEP	-100＜△Nfo≤-50
		-5STEP	△Nfo≤-100

Optionally, in order to ensure normal operation of the outdoor fan, the STEP size of the rotation speed needs to be within a certain range, that is, STEPmin is equal to or less than STEP is equal to or less than STEPmax. STEPmin is the minimum value of the rotational speed step, and STEPmax is the maximum value of the rotational speed step.

Based on the embodiment shown in fig. 11, the rotation speed adjustment value of the outdoor fan is determined according to the target temperature and the indoor temperature of the current cycle, and the target temperature and the indoor temperature of the previous cycle, so that the outdoor fan can be operated at a proper rotation speed, thereby allowing the indoor temperature to reach the target temperature.
