The present embodiment provides an air conditioner that performs a cooling and heating cycle of the air conditioner by using a compressor, a condenser, an expansion valve, and an evaporator. The cooling and heating cycle includes a series of processes involving compression, condensation, expansion, and evaporation, and supplies a refrigerant medium to the air that has been conditioned and heat-exchanged.

The compressor compresses a refrigerant gas in a high-temperature and high-pressure state 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 heat is released to the surrounding environment through the condensation process.

The expansion valve expands the high-temperature and high-pressure liquid-phase refrigerant condensed in the condenser into a low-pressure liquid-phase refrigerant. The evaporator evaporates the refrigerant expanded in the expansion valve and returns the refrigerant gas in a low-temperature and low-pressure state to the compressor. The evaporator can achieve a refrigerating effect by heat exchange with a material to be cooled using latent heat of evaporation of a refrigerant. The air conditioner can adjust the temperature of the indoor space throughout the cycle.

The outdoor unit of the air conditioner refers to a portion of a refrigeration cycle including a compressor, an outdoor heat exchanger, and an outdoor fan, the indoor unit of the air conditioner includes a portion of an indoor heat exchanger and an indoor fan, and a throttling device (e.g., a capillary tube or an electronic expansion valve) may be provided in the indoor unit or the outdoor unit.

The indoor heat exchanger and the outdoor heat exchanger are switched to be used as a condenser or an evaporator, a four-way valve is generally adopted, and specific reference is made to the arrangement of a conventional air conditioner, which is not described herein again.

The refrigeration working principle of the air conditioner is as follows: the compressor works to enable the interior of the indoor heat exchanger (in the indoor unit, the evaporator at the moment) to be in an ultralow pressure state, liquid refrigerant in the indoor heat exchanger is rapidly evaporated to absorb heat, air blown out by the indoor fan is cooled by the coil pipe of the indoor heat exchanger to become cold air which is blown into a room, the evaporated and vaporized refrigerant is compressed by the compressor, is condensed into liquid in a high-pressure environment in the outdoor heat exchanger (in the outdoor unit, the condenser at the moment) to release heat, and the heat is dissipated into the atmosphere through the outdoor fan, so that the refrigeration effect is achieved by circulation.

The heating working principle of the air conditioner is as follows: the gaseous refrigerant is pressurized by the compressor to become high-temperature and high-pressure gas, and the high-temperature and high-pressure gas enters the indoor heat exchanger (the condenser at the moment), is condensed, liquefied and released heat to become liquid, and simultaneously heats indoor air, so that the aim of increasing the indoor temperature is fulfilled. The liquid refrigerant is decompressed by the throttling device, enters the outdoor heat exchanger (an evaporator at the moment), is evaporated, gasified and absorbs heat to form gas, absorbs the heat of outdoor air (the outdoor air becomes cooler) to form gaseous refrigerant, and enters the compressor again to start the next cycle.

Specifically, since the supporting member 22 is disposed at one side of the heat exchanging part 21, the air may be blocked by the supporting member 22 during the air flow passing through the heat exchanging part 21, thereby affecting the smoothness of the air flow. By arranging the plurality of first ventilation holes 223 on the support member 22, the first ventilation holes 223 can ensure smooth air flow through the support member 22, thereby reducing air resistance.

In some embodiments of the present application, in order to facilitate the installation of the reinforcing member 23, the reinforcing member 23 is provided with a slot (not labeled) into which an edge of the heat exchanging part 21 is inserted at a corresponding side.

Specifically, the heat exchanging portion 21 is inserted into a slot formed in the reinforcing member 23 to connect the heat exchanging portion 21 and the reinforcing member 23, so that the assembling efficiency can be effectively improved during the field assembly. At the same time, when the indoor heat exchanger 2 is installed in the casing 1, the reinforcing member 23 abuts against the inner wall of the casing 1, and the reinforcing member 23 is positioned and fixed by the casing 1.

In order to sufficiently utilize the heat exchange area of the heat exchanging unit 21, the reinforcing member 23 has a U-shaped cross section, and a plurality of second ventilation holes 231 are formed in the upper surface of the reinforcing member 23. The second ventilation holes 231 allow the air flow to pass through the reinforcing member 23, and the heat exchange is performed by using the edge of the heat exchanging part 21, thereby improving the heat exchange efficiency.

The foregoing is directed to preferred embodiments of the present invention, other and further embodiments of the utility model may be devised without departing from the basic scope thereof, and the scope thereof is determined by the claims that follow. However, any simple modification, equivalent change and modification of the above embodiments according to the technical essence of the present invention are within the protection scope of the technical solution of the present invention.
