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.

Therefore, the periphery of the shell 1 is uniformly distributed with the outdoor heat exchanger 2, and correspondingly, the periphery of the shell 1 is provided with the air inlets so as to meet the requirement of uniform air inlet heat exchange of the periphery of the outdoor heat exchanger 2.
Likewise, for the outdoor heat exchanger 2, a split design may also be adopted, i.e. the outdoor heat exchanger 2 comprises two sub heat exchanges (not shown), and the two sub heat exchanges are oppositely arranged in the casing 1. In some embodiments of the present application, the cross section of the sub heat exchange is a U-shaped structure.
In some embodiments of the present application, a partition 12 is disposed in the housing 1, and an electrical installation cavity is formed between the partition 12 and a bottom plate of the housing 1.
Specifically, the air inlet cavity is surrounded by the outdoor heat exchanger 2, the shell 1 and the bottom partition plate 12. Since the outdoor heat exchangers 2 are distributed around the periphery, in order to facilitate the placement of electronic components such as electronic control boards, a partition plate 12 is disposed in a lower region inside the casing 1, so that an electrical installation cavity is formed at the bottom of the casing 1 by the partition plate 12.
