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.
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 serve as a condenser or an evaporator. The air conditioner performs a heating mode when the indoor heat exchanger serves as a condenser, and performs a cooling mode when the indoor heat exchanger serves as an evaporator.
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.

The assembly between the upper housing 12 and the lower housing 13 may be a clamping, a screw connection, and the like, which is not limited and described herein.
In some embodiments of the present application, in order to reduce the externally exposed screws, a clamping manner is preferably adopted, specifically, a side wall of the lower housing 13 is provided with a guide protrusion 131 and a catch 132, a side wall of the upper housing 12 is provided with a guide groove 124 and a limiting hole 125, the guide protrusion 131 is inserted into the guide groove 124, and the catch 132 is clamped in the limiting hole 125.
Specifically, in the assembling process, the upper shell 12 is disposed on the sheet metal top plate 11, and the fixing manner of the upper shell and the sheet metal top plate can adopt conventional connection manners such as screws. And the lower housing 13 is guided and installed by the cooperation of the guide protrusion 131 and the guide groove 124, and finally, the latch 132 is clamped in the limiting hole 125.
Under the effect of buckle 132 and spacing hole 125, can ensure firm connection between upper casing 12 and lower casing 13, simultaneously, because the parcel of lower casing 13 is in the outside of upper casing 12 for whole outward appearance need not the screw and shows.
In some embodiments of the present application, since the indoor heat exchanger 2 needs to be connected to the refrigerant pipeline, and the indoor fan 3 needs to be connected to the cable, in order to facilitate the outward leading and implement the requirement of hiding the wiring, a channel 126 for laying the pipeline may be provided on the upper housing 12, and the channel 126 is close to the rear sidewall of the upper housing 12.
Specifically, in the installation process, the refrigerant pipeline and the cable are led out from the upper shell 12 and are wired through the channel 126, the refrigerant pipeline and the cable are located in the channel 126, exposure of the pipeline is reduced, on one hand, the overall appearance effect is optimized, on the other hand, safe and reliable wiring of the pipeline can be guaranteed, and the later-stage use safety is improved.
The foregoing is directed to preferred embodiments of the present invention, other and further embodiments of the invention 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.
