Fig. 1 is an air path diagram of a new air window conditioner in a refrigerant leakage mode according to an embodiment of the present invention, which shows a device layout of the new air window conditioner. Fig. 2 shows a schematic structural view of a fresh air window air conditioner according to an embodiment of the present invention. Referring to fig. 1-2, the fresh air window air conditioner 100 may include at least a cabinet 110, an emergency fan 133, a control device 180, a first fan 122, a second fan 123, a third fan 132, a heat regenerator 124, a first heat exchanger 121, a second heat exchanger 131, a compressor 126, a four-way reversing valve 127, and an expansion valve 137. The four-way reversing valve 127 is connected to the compressor 126, the first heat exchanger 121, and the second heat exchanger 131 through pipelines, the first heat exchanger 121 is further connected to the second heat exchanger 131 through a pipeline, and the expansion valve 137 is disposed on the pipeline between the first heat exchanger 121 and the second heat exchanger 131.

As shown in fig. 1, the housing 110 may define an outer chamber 130 and an inner chamber 120. The box body part of the indoor cavity 120 is provided with an emergency air port 134, a first air port 135 and a third air port 136 which are communicated with the indoor environment, the third fan 132, the second heat exchanger 131 and the emergency fan 133 are all arranged in the indoor cavity 120, the emergency fan 133 is arranged at the emergency air port 134, and the third fan 132 is arranged at the second heat exchanger 131. The outdoor chamber 130 is provided at a box portion thereof with a second air port 125 communicating with an outdoor environment, the first fan 122, the second fan 123, the compressor 126, the four-way reversing valve 127, the first heat exchanger 121, and the heat regenerator 124 may be disposed in the outdoor chamber 130, the first fan 122 may be disposed at the second air port 125, and the second fan 123 may be disposed at the first heat exchanger 121.

In practical applications, the regenerator 124 may also be disposed in the chamber cavity 120, and the position of the regenerator 124 is not particularly limited in the present invention.

As shown in fig. 1, in the fresh air window air conditioner 100 in the cooling mode, a flow path of the refrigerant is indicated by a solid arrow; in the heating mode of the fresh air window air conditioner, the flow path of the refrigerant is indicated by a dotted arrow. In the cooling mode, the first heat exchanger 121 is a condenser, and the second heat exchanger 131 is an evaporator; in the heating mode, the first heat exchanger 121 is an evaporator, and the second heat exchanger 131 is a condenser.

The fresh air window air conditioner provided by the invention has multiple operation modes, specifically comprises a common mode, a fresh air mode and a refrigerant leakage mode, and the switching among the modes is described below.

As shown in fig. 1, the emergency air outlet 134 and the outdoor cavity 130 are communicated by the emergency air duct 150, and when the control device 180 determines that the fresh air window air conditioner 100 has a refrigerant leakage event, especially for the case of using the R290 refrigerant, the control device 180 controls the fresh air window air conditioner to switch the fresh air window air conditioner 100 to the refrigerant leakage mode. Specifically, the control device 180 opens the emergency air port 134 and the emergency fan 133, and closes the other air ports, so that the emergency fan 133 sucks indoor air from the emergency air port 134, and causes the sucked indoor air to carry the leaked refrigerant to form an air flow flowing to the outdoor cavity 130 through the emergency air duct 150, thereby preventing the leaked refrigerant from flowing to the indoor environment, ensuring the safety of the R290 refrigerant in the air conditioner, and further ensuring the personal safety of the user.

Fig. 2 shows an air path diagram of a fresh air window air conditioner in a normal mode according to an embodiment of the invention. As shown in fig. 2, when the fresh air window air conditioner 100 is in the normal mode, the first air opening 135 and the third air opening 136 are in the open state, and the emergency air opening 134 and the second air opening 125 are in the closed state. The first air port 135 and the third air port 136 are communicated by a return air duct 170, the air flow of the return air duct 170 flows through the second heat exchanger 131, and the third fan 132 is arranged at the second heat exchanger 131. In this mode, the second heat exchanger 131 only exchanges heat with the indoor air in a circulating manner, so that the cooling or heating speed of the indoor environment can be increased.

If the fresh air window air conditioner 100 is in the normal mode, and the control device 180 determines that a refrigerant leakage event occurs, the control device 180 controls the first air opening 135 and the third air opening 136 to be closed, and controls the emergency fan 133 and the emergency air opening 134 to be opened, so that the emergency fan 133 sucks in indoor air from the emergency air opening 134, and the sucked indoor air carries the leaked refrigerant to form an air flow flowing to the outdoor cavity 130 through the emergency air duct 150, so as to ensure the personal safety of a user.

Fig. 3 shows an air path diagram of a fresh air window air conditioner in a fresh air mode according to an embodiment of the invention. As shown in fig. 3, when the fresh air window air conditioner is in the fresh air mode, the first air port 135, the second air port, the third air port 136, the emergency air port 134, the first fan 122 and the emergency fan 133 are all opened. The first air opening 135 and the second air opening 125 are communicated by the air supply duct 160, and the air flows of the return air duct 170 and the air supply duct 160 both flow through the second heat exchanger 131. In this mode, the first fan 122 sucks in outdoor air from the second air port 125 and causes the sucked outdoor air to form an air flow flowing to the first air port 135 via the supply air duct 160, so that fresh air can be continuously supplied to the room; the emergency fan 133 sucks the indoor air from the emergency wind opening 134 and induces the sucked indoor air to form an air flow toward the outdoor space 130 through the emergency wind tunnel 150, so that the harmful gas in the room can be exhausted. The whole fresh air function is realized.

It should be noted that, in the fresh air mode, the control device controls the third air opening 136 to open, so that the cooling or heating speed of the indoor environment can be increased under the condition that fresh air can be continuously provided for the indoor and harmful gases in the indoor can be removed.

In addition, the emergency tuyere 134 is disposed far from the first tuyere 135 with respect to the third tuyere 136. This ensures that the air entering the emergency air port 134 is air that is in the room for a relatively long time, rather than air that has just flowed out of the first air port 135, thereby ensuring the heat exchange efficiency of the fresh air window air conditioner 100.

In addition, a filter device is disposed at the first air opening 135, which can filter out dust and impurities in the air, so that clean air can enter the indoor environment.

After the fresh air function of the air conditioner is started, the energy consumption is generally high, and in order to reduce the energy consumption after the fresh air function of the air conditioner is started, as shown in fig. 3, the air flows in the emergency air duct 150 and the air supply air duct 160 of the invention are both configured to flow through the heat regenerator 124, the heat regenerator 124 may be a total heat exchanger, and the heat regenerator 124 may perform heat and moisture recovery and heat exchange on the air flow in the air supply air duct 160 and the air flow in the emergency air duct 150.

Further, the first heat exchanger 121 is disposed downstream of the emergency air duct 150 in the air direction and is communicated with the outdoor environment, after the air flow in the emergency air duct 150 flows through the heat regenerator 124, the air flow flows to the first heat exchanger 121, and the first heat exchanger 121 can recover residual energy in the air flow for self heat exchange. The air, after heat exchange via the first heat exchanger 121, is finally forced to form an airflow towards the outdoor environment via the second fan 123. Further reducing the energy consumption of the air conditioner after the fresh air function is started.

If the fresh air window air conditioner 100 is in the fresh air mode, and the control device 180 determines that a refrigerant leakage event occurs, the control device controls the first air port 135, the third air port 136, the second air port 125, and the first fan 122 to be closed, and the emergency fan 133 and the emergency air port 134 are kept in an open state, so that the emergency fan 133 sucks indoor air from the emergency air port 134, and the sucked indoor air carries the leaked refrigerant to form an air flow flowing to the outdoor cavity 130 through the emergency air duct 150, thereby ensuring the personal safety of a user.

At this time, if the control device 180 receives an instruction for switching the fresh air window air conditioner 100 from the fresh air mode to the normal mode, the second air port 125, the emergency air port 134, the emergency fan 133, and the first fan 122 are controlled to be closed, and the other air ports are kept in the open state. On the contrary, if the control device 180 receives an instruction about switching the fresh air window air conditioner 100 from the normal mode to the fresh air mode, the control device 180 controls all the air ports and the fans at the air ports to be turned on.

The invention provides a fresh air window air conditioner 100 which comprises an indoor cavity 120 and an outdoor cavity 130, wherein an emergency air port 134, a first air port 135 and a third air port 136 which are communicated with an indoor environment are arranged on a box body part of the indoor cavity 120; the body portion of the outdoor chamber 130 is provided with a second tuyere 125 communicating with the outdoor environment. The control device 180 can control the opening and closing of the plurality of air ports to realize various operation modes of the air conditioner, and can be switched randomly, so that the use experience of a user is greatly enriched. In addition, under the condition that the R290 refrigerant is adopted, when the refrigerant leaks, the control device 180 controls the fresh air window air conditioner 100 to switch to the refrigerant leakage mode, that is, only the emergency air port 134 and the emergency fan 133 are opened, and the fans at the other air ports and the air ports are closed, so that the emergency fan 133 sucks in the indoor air from the emergency air port 134, and promotes the sucked indoor air carrying the leaked refrigerant to flow to the outdoor cavity 130 through the emergency air duct 150, so as to prevent the leaked refrigerant from flowing to the indoor as much as possible. In addition, in the fresh air mode, the air flows in the air supply duct 160 and the emergency air duct 150 are both configured to flow through the heat regenerator 124, so that the heat regenerator 124 can exchange heat with the air flows in the air supply duct 160 and the emergency air duct 150, thereby reducing energy consumption after the fresh air mode of the air conditioner is started, further, the first heat exchanger 121 can perform secondary energy recovery on the air flow flowing through the heat regenerator, and further reducing energy consumption after the fresh air mode of the air conditioner is started.

Thus, it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the invention have been illustrated and described in detail herein, many other variations or modifications consistent with the principles of the invention may be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the invention.
