[0047] In the description of this utility model, "multiple" means two or more, and "several" means one or more.

[0048] An air conditioner according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0049] likeFigures 1-11 As shown, the air conditioner according to the embodiment of the present utility model may include a compressor 100. The compressor 100 has an inlet 110 and an outlet 120. Refrigerant can flow out of the compressor 100 through the outlet 120 and flow into the compressor 100 through the inlet 110. The refrigerant flowing out of the compressor 100 is a high-temperature and high-pressure gaseous refrigerant.

[0050] Among them, a gas-liquid separator 130 can be provided at the inlet 110 of the compressor 100. The gas-liquid separator 130 can prevent liquid refrigerant from flowing directly back to the compressor 100, thereby avoiding the phenomenon of "liquid slugging" and protecting the compressor 100 from damage.

[0051] An air conditioner may include an outdoor heat exchanger 200. One end of the outdoor heat exchanger 200 is connected to an outlet 120. When the air conditioner is running, the refrigerant flows out through the outlet 120 and flows to the outdoor heat exchanger 200. At this time, the outdoor heat exchanger 200 acts as a condenser. The high-temperature refrigerant releases heat to the outdoor air through the outdoor heat exchanger 200 and becomes a medium-temperature or low-temperature refrigerant.

[0052] The air conditioner may include an indoor heat exchanger 300. One end of the indoor heat exchanger 300 is connected to the inlet 110, and the other end of the indoor heat exchanger 300 is connected to the other end of the outdoor heat exchanger 200. When the air conditioner is running, the refrigerant that has released heat through the outdoor heat exchanger 200 flows to the indoor heat exchanger 300. At this time, the indoor heat exchanger 300 can act as an evaporator. Medium-temperature or low-temperature refrigerant can absorb heat from the indoor air through the indoor heat exchanger 300 to reduce the temperature of the indoor air and achieve cooling of the room.

[0053] In this embodiment, the air conditioner is typically used in high-temperature areas. This air conditioner does not require switching the flow direction of the refrigerant. The refrigerant only needs to flow through the compressor 100, the outdoor heat exchanger 200 and the indoor heat exchanger 300 in sequence. That is, the air conditioner in this embodiment only needs to cool the room through the indoor heat exchanger 300.

[0054] The air conditioner may also include a cooler 400, one end of which is connected to the other end of the outdoor heat exchanger 200, and the other end of the cooler 400 is connected to the other end of the indoor heat exchanger 300. When the air conditioner is running, the cooler 400 acts as an evaporator. By connecting the cooler 400 to the outdoor heat exchanger 200, when the air conditioner is running, the refrigerant can flow to the cooler 400 after releasing heat through the outdoor heat exchanger 200. The cooler 400 acts as an evaporator, allowing the refrigerant to absorb air temperature through the cooler 400, thereby lowering the temperature of the air flowing to the outdoor heat exchanger 200.

[0055] The cooler 400 is positioned adjacent to the outdoor heat exchanger 200 to dissipate heat and cool the outdoor heat exchanger 200. For example, the cooler 400 can be positioned side by side with the outdoor heat exchanger 200.

[0056] In this way, the cooler 400 can be located close to the outdoor heat exchanger 200. When the air conditioner is running, the cooler 400 can absorb the temperature of the air near the outdoor heat exchanger 200 to lower the temperature of the air flowing towards the outdoor heat exchanger 200. Even if the ambient temperature is high, it can ensure that the outdoor heat exchanger 200 is cooled by the cooler air. The cooler air has a better cooling effect on the outdoor heat exchanger 200, thus preventing the heat exchange tubes of the outdoor heat exchanger 200 from getting too hot. This can prevent the air conditioner from being easily damaged due to excessive system pressure, so that the air conditioner can still operate at full load or high load in high temperature environments. The air conditioner does not need to reduce its frequency. In high temperature or ultra-high temperature environments, the cooling capacity of the air conditioner is more sufficient, the cooling effect is better, and the user experience is better.

[0057] Thus, the cooler 400 of the air conditioner according to this embodiment can act as an evaporator to reduce the temperature of the air flowing to the outdoor heat exchanger 200. The low temperature air has a better heat dissipation and cooling effect on the outdoor heat exchanger 200, thereby preventing the outdoor heat exchanger 200 from getting too hot and ensuring that the air conditioner has a more sufficient cooling capacity in high or ultra-high temperature environments.

[0058] In some specific embodiments of this utility model, such as Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the air conditioner may also include a first throttling device 500, which is connected between the other end of the outdoor heat exchanger 200 and one end of the cooler 400. The first throttling device 500 is used to throttle and cool the refrigerant flowing to the cooler 400.

[0059] In other words, the first throttling device 500 is located between the outdoor heat exchanger 200 and the cooler 400. When the refrigerant flows to the cooler 400, it needs to pass through the first throttling device 500 first. The first throttling device 500 can throttle and cool the refrigerant, further reducing the temperature of the refrigerant and ensuring that the temperature of the refrigerant flowing to the cooler 400 is relatively low. This can improve the heat exchange efficiency between the low-temperature refrigerant and the air through the cooler 400. The cooler 400 can more effectively reduce the temperature of the air flowing to the outdoor heat exchanger 200, further improving the heat dissipation and cooling effect of the low-temperature air on the outdoor heat exchanger 200, and more effectively preventing the temperature of the outdoor heat exchanger 200 from becoming too high.

[0060] In some specific embodiments of this utility model, such asFigure 7 As shown, the air conditioner may also include an electronic control component 600, which is electrically connected to the compressor 100. For example, the electronic control component 600 may be an electronic control board.

[0061] The air conditioner may also include a heat dissipation component 700, which is connected between the other end of the outdoor heat exchanger 200 and the first throttling device 500. The heat dissipation component 700 uses refrigerant to dissipate heat and cool the electronic control component 600.

[0062] Therefore, the medium-temperature or low-temperature refrigerant flowing out from the other end of the outdoor heat exchanger 200 can flow to the heat dissipation component 700. The low-temperature refrigerant can absorb the heat of the electronic control component 600 through the heat dissipation component 700, thereby preventing the temperature of the electronic control component 600 from getting too high, so that the electronic control component 600 can operate in a medium-temperature or low-temperature environment. The operation of the electronic control component 600 is more stable and reliable, and the safety is higher.

[0063] In addition, the heat dissipation component 700 is disposed between the outdoor heat exchanger 200 and the first throttling device 500. In this way, the refrigerant flowing through the heat dissipation component 700 increases in temperature after absorbing heat from the electronic control component 600. The first throttling device 500 can further throttle and cool the refrigerant flowing out of the heat dissipation component 700 to ensure that the temperature of the refrigerant flowing to the cooler 400 is lower. This allows the refrigerant to better absorb heat from the outside air through the cooler 400, so as to more effectively dissipate heat and cool the outdoor heat exchanger 200 through the low-temperature airflow.

[0064] Furthermore, such as Figures 7-11 As shown, the heat dissipation assembly 700 may include a refrigerant flow pipe 710, which is connected between the other end of the outdoor heat exchanger 200 and the first throttling device 500. In this way, the refrigerant flowing out of the outdoor heat exchanger 200 can flow to the first throttling device 500 through the refrigerant flow pipe 710, and the refrigerant can exchange heat with the outside through the refrigerant flow pipe 710.

[0065] Additionally, the heat dissipation assembly 700 may include a heat-conducting plate 720, which is attached and fixed to the electronic control assembly 600. The heat-conducting plate 720 covers at least a portion of the refrigerant flow pipe 710 in the circumferential direction, and the refrigerant in the refrigerant flow pipe 710 exchanges heat with the electronic control assembly 600 through the heat-conducting plate 720.

[0066] Wherein, the heat-conducting plate 720 covering at least a portion of the refrigerant flow pipe 710 in the circumferential direction means that the heat-conducting plate 720 can completely cover the refrigerant flow pipe 710 in the circumferential direction, or the heat-conducting plate 720 can only cover a portion of the refrigerant flow pipe 710 in the circumferential direction.

[0067] By setting up the heat-conducting plate 720, the heat exchange area between the heat dissipation component 700 and the electronic control component 600 can be increased. As a result, the refrigerant flowing through the refrigerant circulation pipe 710 can exchange heat with the electronic control component 600 through the refrigerant circulation pipe 710 and the heat-conducting plate 720. In this way, the refrigerant can absorb the heat of the electronic control component 600, thereby reducing the temperature of the electronic control component 600 and preventing the temperature of the electronic control component 600 from becoming too high.

[0068] In some embodiments of this utility model, such as Figures 7-9 As shown, the heat-conducting plate 720 may include an upper heat-conducting plate 721 and a lower heat-conducting plate 722. The refrigerant flow pipe 710 is disposed between the upper heat-conducting plate 721 and the lower heat-conducting plate 722. In this way, the upper heat-conducting plate 721 and the lower heat-conducting plate 722 can completely cover the refrigerant flow pipe 710 circumferentially. This not only improves the connection stability between the heat-conducting plate 720 and the refrigerant flow pipe 710, but also increases the contact area between the heat-conducting plate 720 and the refrigerant flow pipe 710. The heat exchange efficiency between the heat-conducting plate 720 and the refrigerant flow pipe 710 is higher, and the heat dissipation effect of the heat dissipation component 700 on the electronic control component 600 is better.

[0069] Alternatively, in some embodiments, such as Figure 10 and Figure 11 As shown, the heat-conducting plate 720 can also retain only the upper heat-conducting plate 721. The refrigerant flow pipe 710 can be connected and fixed to the upper heat-conducting plate 721 through the connector. This simplifies the structure of the heat dissipation component 700, facilitates assembly, and the heat dissipation component 700 can still ensure a large contact area with the electronic control component 600 through the upper heat-conducting plate 721, resulting in higher heat exchange efficiency.

[0070] In some specific embodiments of this utility model, such as Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the air conditioner may also include a second throttling device 800, which is connected between the other end of the outdoor heat exchanger 200 and the heat dissipation component 700. The second throttling device 800 is used to throttle and cool the refrigerant flowing to the heat dissipation component 700.

[0071] In other words, the second throttling device 800 is located between the outdoor heat exchanger 200 and the heat dissipation component 700. When the refrigerant flowing out of the outdoor heat exchanger 200 flows to the heat dissipation component 700, it needs to pass through the second throttling device 800 first. The second throttling device 800 can throttle and cool the refrigerant so that the temperature of the refrigerant flowing out of the outdoor heat exchanger 200 can be further reduced. This ensures that the temperature of the refrigerant flowing into the heat dissipation component 700 is lower, which can improve the heat exchange efficiency of the refrigerant through the heat dissipation component 700 and the electrical control component 600, resulting in better heat dissipation for the electrical control component 600.

[0072] Moreover, it is understandable that when the outdoor ambient temperature is too high, the temperature of the refrigerant after releasing heat through the outdoor heat exchanger 200 will still be high. By setting the second throttling device 800 to throttle and cool the refrigerant flowing out of the outdoor heat exchanger 200, even if the outdoor ambient temperature is high, it can more effectively ensure that the temperature of the refrigerant flowing to the heat dissipation component 700 is lower, thereby improving the heat dissipation effect of the refrigerant on the electronic control component 600 through the heat dissipation component 700.

[0073] In some specific embodiments of this utility model, such as Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the air conditioner may also include a third throttling device 900, which is connected between the other end of the cooler 400 and the other end of the indoor heat exchanger 300. The third throttling device 900 is used to throttle and cool the refrigerant flowing to the indoor heat exchanger 300.

[0074] That is, the third throttling device 900 is located between the cooler 400 and the indoor heat exchanger 300. In this way, the third throttling device 900 can throttle and cool the refrigerant flowing out of the cooler 400. Even if the temperature of the refrigerant flowing through the cooler 400 rises after absorbing heat from the outdoor air, the third throttling device 900 can still ensure that the temperature of the refrigerant entering the indoor heat exchanger 300 is lower. The low-temperature refrigerant has a higher heat exchange efficiency with the indoor air through the indoor heat exchanger 300, and the refrigerant flowing through the indoor heat exchanger 300 can absorb heat from the indoor air more fully, which is beneficial to improving the cooling effect of the air conditioner.

[0075] In some specific embodiments of this utility model, the first throttling device 500, the second throttling device 800, and the third throttling device 900 are all adjustable flow elements. For example, the first throttling device 500, the second throttling device 800, and the third throttling device 900 can be throttle valves or expansion valves.

[0076] like Figure 3 As shown, when the outdoor temperature is lower than the preset temperature value, the first throttling device 500 and the second throttling device 800 are turned on but do not throttle, while the third throttling device 900 is turned on and throttles. When the outdoor temperature is not lower than the preset temperature value, the first throttling device 500, the second throttling device 800 and the third throttling device 900 are all turned on and throttle.

[0077] The preset temperature value can be the boundary value for high temperature. When the outdoor temperature is lower than the preset temperature value, it means that the outdoor temperature is low or medium temperature. When the outdoor temperature is greater than or equal to the preset temperature, it means that the outdoor temperature is high temperature.

[0078] Therefore, when the outdoor temperature is not lower than the preset temperature value, the air conditioner operates in a high-temperature or ultra-high-temperature environment. At this time, the first throttling device 500, the second throttling device 800, and the third throttling device 900 are all activated and throttled. This ensures that the temperature of the refrigerant flowing to the heat dissipation component 700, the refrigerant flowing to the cooler 400, and the refrigerant flowing to the indoor heat exchanger 300 can all be kept low. This ensures that the heat dissipation component 700 can effectively dissipate heat to the electronic control component 600, and that the cooler 400 can effectively cool the air flowing to the outdoor heat exchanger 200. This further improves the heat dissipation and cooling effect on the outdoor heat exchanger 200, and allows the refrigerant to fully absorb heat from the indoor air through the indoor heat exchanger 300, resulting in a better cooling effect for the indoor environment.

[0079] When the outdoor temperature is lower than the preset temperature value, the air conditioner operates in a medium or low temperature environment. The temperature of the outside environment has little impact on the electronic control component 600 and the outdoor heat exchanger 200. The refrigerant can directly absorb the heat from the electronic control component 600 through the heat dissipation component 700 to meet the heat dissipation requirements of the electronic control component 600. The refrigerant can also directly dissipate heat and cool the outdoor heat exchanger 200 through the cooler 400 to meet the heat dissipation requirements of the outdoor heat exchanger 200. The first throttling device 500 and the second throttling device 800 do not need to throttle the refrigerant, and the flow of the refrigerant can be smoother.

[0080] In some other specific embodiments of this utility model, the first throttling device 500 and the second throttling device 800 are normally open throttling elements, and the third throttling device 900 is an adjustable flow element. For example, the first throttling device 500 and the second throttling device 800 can be capillary tubes, and the third throttling device 900 can be a throttling valve or an expansion valve.

[0081] And, as Figure 4 and Figure 5 As shown, the air conditioner also includes a first on / off valve 510 and a second on / off valve 610. For example, the first on / off valve 510 and the second on / off valve 610 can be solenoid valves.

[0082] Specifically, the first on / off valve 510 is connected between one end of the heat dissipation assembly 700 and the cooler 400, and the first on / off valve 510 is connected in parallel with the first throttling device 500. The second on / off valve 810 is connected between the other end of the outdoor heat exchanger 200 and the heat dissipation assembly 700, and the second on / off valve 810 is connected in parallel with the second throttling device 800.

[0083] Among them, such as Figure 6As shown, when the outdoor temperature is lower than the preset temperature value, the first on-off valve 510 and the second on-off valve 810 are opened, and the third throttling device 900 is opened and throttles; when the outdoor temperature is not lower than the preset temperature value, the first on-off valve 510 and the second on-off valve 810 are closed, and the third throttling device 900 is opened and throttles.

[0084] The preset temperature value can be the boundary value for high temperature. When the outdoor temperature is lower than the preset temperature value, it means that the outdoor temperature is low or medium temperature. When the outdoor temperature is greater than or equal to the preset temperature, it means that the outdoor temperature is high temperature.

[0085] Therefore, when the outdoor temperature is not lower than the preset temperature value, the air conditioner operates in a high-temperature or ultra-high-temperature environment. At this time, the first shut-off valve 510 and the second shut-off valve 810 are closed, and the third throttling device 900 is opened and throttles. This ensures that the refrigerant flowing to the heat dissipation component 700 can first flow through the first throttling device 500 for throttling and cooling, and that the refrigerant flowing to the cooler 400 can flow through the second throttling device 800 for throttling and cooling. This ensures that the temperatures of the refrigerant flowing to the heat dissipation component 700, the cooler 400, and the indoor heat exchanger 300 are all relatively low. This, in turn, ensures that the heat dissipation component 700 has a better heat dissipation effect on the electronic control component 600, and that the cooler 400 has a better cooling effect on the air flowing to the outdoor heat exchanger 200. This improves the heat dissipation and cooling effect on the outdoor heat exchanger 200, and allows the refrigerant to fully absorb heat from the indoor air through the indoor heat exchanger 300, resulting in a better cooling effect for the indoor environment.

[0086] When the outdoor temperature is lower than the preset temperature, the air conditioner operates in a medium or low temperature environment. At this time, the temperature of the outside environment has little impact on the electronic control component 600 and the outdoor heat exchanger 200. The refrigerant can directly absorb the heat from the electronic control component 600 through the heat dissipation component 700 to meet the heat dissipation requirements of the electronic control component 600. The refrigerant can also directly dissipate heat and cool the outdoor heat exchanger 200 through the cooler 400 to meet the heat dissipation requirements of the outdoor heat exchanger 200. At this time, the first on-off valve 510 and the second on-off valve 810 are opened. Since the flow resistance in the first on-off valve 510 is less than the flow resistance in the first throttling device 500, and the flow resistance in the second on-off valve 810 is less than the flow resistance in the second throttling device 800, the refrigerant can flow through the first on-off valve 510 to the heat dissipation component 700 and through the second on-off valve 810 to the cooler 400. That is, the refrigerant does not need to flow through the first throttling device 500 and the second throttling device 800 for throttling and cooling, so that the flow of the refrigerant can be smoother.

[0087] In some specific embodiments of this utility model, the first throttling device 500 is a throttling valve, an expansion valve, or a capillary tube; and / or, the second throttling device 800 is a throttling valve, an expansion valve, or a capillary tube; and / or, the third throttling device 900 is a throttling valve, an expansion valve, or a capillary tube.

[0088] For example, the first throttling device 500 can be one or more of a throttling valve, an expansion valve, or a capillary tube. In this way, the first throttling device 500 can be used to fully throttle and cool the refrigerant flowing to the cooler 400, so as to ensure that the temperature of the refrigerant flowing to the cooler 400 can be lower. The heat exchange efficiency between the refrigerant and the outside air through the cooler 400 is higher, which can effectively reduce the temperature of the air flowing to the outdoor heat exchanger 200 and improve the heat dissipation and cooling effect of the outdoor heat exchanger 200.

[0089] The second throttling device 800 can be one or more of a throttling valve, an expansion valve, or a capillary tube. In this way, the second throttling device 800 can be used to fully throttle and cool the refrigerant flowing to the heat dissipation component 700, so as to ensure that the temperature of the refrigerant flowing to the heat dissipation component 700 can be lower. The heat exchange efficiency between the refrigerant and the electronic control component 600 through the heat dissipation component 700 can be higher, thereby improving the heat dissipation effect of the heat dissipation component 700 on the electronic control component 600.

[0090] The third throttling device 900 can be one or more of a throttling valve, an expansion valve, or a capillary tube. This allows the third throttling device 900 to fully throttle and cool the refrigerant flowing to the indoor heat exchanger 300, ensuring that the temperature of the refrigerant flowing to the indoor heat exchanger 300 is lower. This results in higher heat exchange efficiency between the refrigerant and the indoor air through the indoor heat exchanger 300, thereby improving the cooling effect of the air conditioner.

[0091] In some specific embodiments of this utility model, the air conditioner may also include an outdoor fan (not shown in the figure). The outdoor fan is used to drive outdoor air to form a heat exchange airflow. The heat exchange airflow flows to the outdoor heat exchanger 200 and exchanges heat with the outdoor heat exchanger 200. The outdoor fan can increase the flow rate of outdoor air, thereby improving the heat exchange efficiency between the cooler 400 and the outdoor air. The cooler 400 has a better heat dissipation and cooling effect on the outdoor heat exchanger 200.

[0092] The cooler 400 is arranged parallel to the outdoor heat exchanger 200 and is located upstream of the outdoor heat exchanger 200. The heat exchange airflow flows through the cooler 400 and the outdoor heat exchanger 200 in sequence. Thus, the outdoor fan can drive the heat exchange airflow to exchange heat with the cooler 400 first, and then flow to the outdoor heat exchanger 200 to dissipate heat and cool it down. This ensures that the airflow cooled by the cooler 400 can flow more effectively to the outdoor heat exchanger 200. The structural design is more reasonable and further improves the heat dissipation and cooling efficiency of the cooler 400 on the outdoor heat exchanger 200.

[0093] An air conditioner according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0094] like Figures 1-11 As shown, the air conditioner according to an embodiment of the present invention may include a compressor 100, which has an inlet 110 and an outlet 120. Refrigerant can flow out of the compressor 100 through the outlet 120 and flow into the compressor 100 through the inlet 110. The refrigerant flowing out of the compressor 100 is a high-temperature, high-pressure gaseous refrigerant. A gas-liquid separator may be provided at the inlet 110 of the compressor 100. The gas-liquid separator can prevent liquid refrigerant from flowing directly back into the compressor 100, thereby avoiding the "liquid slugging" phenomenon and protecting the compressor from damage.

[0095] An air conditioner may include an outdoor heat exchanger 200.

[0096] An air conditioner may include an indoor heat exchanger 300, a compressor 100, an outdoor heat exchanger 200, and the indoor heat exchanger 300 connected to form a refrigerant circuit.

[0097] For example, one end of the indoor heat exchanger 300 can be connected to the outlet 120 of the compressor 100, one end of the outdoor heat exchanger 200 can be connected to the inlet 110 of the compressor 100, and the other end of the indoor heat exchanger 300 can be connected to the other end of the outdoor heat exchanger 200. In this way, when the air conditioner is running, the indoor heat exchanger 300 can act as a condenser and the outdoor heat exchanger 200 can act as an evaporator, thereby enabling the indoor heat exchanger 300 to provide indoor heating. Alternatively, one end of the indoor heat exchanger 300 can be connected to the inlet 110 of the compressor 100, one end of the outdoor heat exchanger 200 can be connected to the outlet 120 of the compressor 100, and the other end of the indoor heat exchanger 300 can be connected to the other end of the outdoor heat exchanger 200. In this way, when the air conditioner is running, the outdoor heat exchanger 200 can act as a condenser and the indoor heat exchanger 300 can act as an evaporator, thereby enabling the indoor heat exchanger 300 to provide indoor cooling. In other words, the air conditioner in this embodiment can switch the direction of refrigerant flow, thereby achieving cooling or heating of the room.

[0098] The air conditioner may also include a cooler 400, which is connected to the refrigerant circuit. When the outdoor heat exchanger 200 acts as a condenser, the cooler 400 acts as an evaporator. In this way, when the air conditioner is cooling the room, the refrigerant can flow to the cooler 400 after releasing heat to the outside through the outdoor heat exchanger 200. The cooler 400 acts as an evaporator, which allows the refrigerant to absorb the temperature of the air through the cooler 400, thereby reducing the temperature of the air flowing to the outdoor heat exchanger 200.

[0099] The cooler 400 is positioned adjacent to the outdoor heat exchanger 200 to dissipate heat and cool the outdoor heat exchanger 200. For example, the cooler 400 can be positioned side by side with the outdoor heat exchanger 200.

[0100] In this way, the cooler 400 can be located close to the outdoor heat exchanger 200. When the air conditioner is cooling the indoor unit, the outdoor heat exchanger 200 acts as a condenser. At this time, the cooler 400 can absorb the temperature of the air near the outdoor heat exchanger 200 to lower the temperature of the air flowing towards the outdoor heat exchanger 200. Even if the ambient temperature is high, it can ensure that the outdoor heat exchanger 200 is cooled by the cooler air. The cooler air has a better cooling effect on the outdoor heat exchanger 200, thus preventing the heat exchange tubes of the outdoor heat exchanger 200 from getting too hot. This can prevent the air conditioner from being easily damaged due to excessive system pressure, so that the air conditioner can still operate at full load or high load in high temperature environments. The air conditioner does not need to reduce its frequency. In high temperature or ultra-high temperature environments, the cooling capacity of the air conditioner is more sufficient, the cooling effect is better, and the user experience is better.

[0101] Thus, the cooler 400 of the air conditioner according to this embodiment can act as an evaporator to reduce the temperature of the air flowing to the outdoor heat exchanger 200. The low temperature air has a better heat dissipation and cooling effect on the outdoor heat exchanger 200, thereby preventing the outdoor heat exchanger 200 from getting too hot and ensuring that the air conditioner has a more sufficient cooling capacity in high or ultra-high temperature environments.

[0102] Other components and operations of the air conditioner according to the embodiments of this utility model are known to those skilled in the art and will not be described in detail here.

[0103] The air conditioner of this invention performs a refrigeration cycle by using a compressor 100, a condenser, an expansion valve, and an evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion, and evaporation, and supplies refrigerant to the conditioned and heat-exchanged air.

[0104] The compressor 100 compresses the refrigerant gas under high temperature and high pressure and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and the heat is released to the surrounding environment through the condensation process.

[0105] The expansion valve expands the high-temperature, high-pressure liquid refrigerant condensed in the condenser into a low-pressure liquid refrigerant. The evaporator evaporates the expanded refrigerant in the expansion valve and returns the low-temperature, low-pressure refrigerant gas to the compressor 100. The evaporator achieves a cooling effect by utilizing the latent heat of refrigerant evaporation to exchange heat with the material being cooled. Throughout the cycle, the air conditioner regulates the temperature and humidity of the indoor space.
