The specific meaning of the above terms in the present utility model will be understood in specific cases by those of ordinary skill in the art.
The air conditioner of the present utility model performs a refrigerating cycle of the air conditioner by using a compressor, a condenser, an expansion valve, and an evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion, and evaporation, and supplies a refrigerant 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 liquid-phase refrigerant in a high-temperature and high-pressure state 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, and the evaporator can achieve a refrigerating effect by exchanging heat with a material to be cooled using latent heat of evaporation of the refrigerant. The air conditioner may adjust the temperature of the indoor space throughout the cycle.
An outdoor unit of an air conditioner refers to a portion of a refrigeration cycle including a compressor and an outdoor heat exchanger, an indoor unit of the air conditioner includes an indoor heat exchanger, and an expansion valve may be provided in the indoor unit or the outdoor unit.
The indoor heat exchanger and the outdoor heat exchanger function as a condenser or an evaporator. When the indoor heat exchanger is used as a condenser, the air conditioner is used as a heater of a heating mode, and when the indoor heat exchanger is used as an evaporator, the air conditioner is used as a cooler of a cooling mode.
The air conditioner shown in fig. 1 includes: the indoor unit 100 of the air conditioner is, for example, an indoor unit (shown in the figure), and the indoor unit is generally mounted on an indoor wall surface WL or the like. For another example, an indoor unit (not shown) is also an indoor unit of an air conditioner.
The air conditioner outdoor unit 200 is generally installed outdoors for heat exchange in an indoor environment. In fig. 1, the air conditioning outdoor unit 200 is located outdoors on the opposite side of the air conditioning indoor unit 100 across the wall surface WL, and the air conditioning outdoor unit 200 is shown by a broken line.
The air conditioner is provided with a refrigerant circuit, and can execute a vapor compression refrigeration cycle by circulating a refrigerant in the refrigerant circuit. The connection pipe is connected to the air conditioning indoor unit 100 and the air conditioning outdoor unit 200 to form a refrigerant circuit in which a refrigerant circulates.
In addition, as shown in fig. 2, the air conditioner has a main control MCU to control the operation of each component in the air conditioner inside, so that each component of the air conditioner operates to achieve each predetermined function of the air conditioner. A remote controller 300 is attached to the air conditioner, and the remote controller 300 has a function of communicating with the main control MCU using, for example, infrared rays or other communication means. The remote controller 300 is used for various controls of the air conditioner by a user, and interaction between the user and the air conditioner is achieved.
