An indoor heat exchanger, generally an evaporator, may be disposed inside the indoor unit of the air conditioner, and an outdoor heat exchanger 121 in the outdoor unit 100 of the air conditioner may be a condenser. Further, the condenser, the evaporator, and the compressor 123 are sequentially connected in a circulating manner to form a refrigerant circulation circuit. At this time, the refrigerant in the evaporator can be sent into the condenser through the compressor 123, and then the refrigerant is cooled by the fresh air outside the condenser, and then the cooled refrigerant is sent out by the condenser, and the refrigerant is sent into the evaporator after throttling, thereby completing the refrigeration cycle.
In addition, the air conditioner may be a central air conditioner, the indoor unit of the air conditioner is disposed indoors, the outdoor unit of the air conditioner 100 is disposed outdoors, a plurality of indoor units of the air conditioner and the outdoor unit of the air conditioner 100 may be disposed in the same indoor space, or may be disposed in different indoor spaces, and different outdoor units of the air conditioner 100 may communicate with each other and cooperate with each other to implement multi-host combined operation.
Illustratively, in the refrigeration process, the compressor 123 compresses a gaseous refrigerant into a high-temperature high-pressure gaseous refrigerant, and then sends the gaseous refrigerant to the condenser for heat dissipation to form a normal-temperature high-pressure liquid refrigerant, the liquid refrigerant enters the evaporator through the capillary tube assembly, because the space of the refrigerant after reaching the evaporator from the capillary tube is suddenly increased, the pressure applied to the refrigerant is reduced, the liquid refrigerant is vaporized to become a gaseous low-temperature refrigerant, so that a large amount of heat is absorbed, the evaporator is cooled, and the centrifugal fan of the indoor air conditioner guides indoor air to blow through the evaporator, so that the indoor air conditioner blows cold air.
The heating process of the air conditioner is the same as the principle of the cooling process, but the flow direction of the refrigerant in the condenser and the evaporator is opposite to that in the cooling process by using the four-way valve, thereby achieving the purpose of heating.
According to the operation principle of the air conditioner, it is known that the refrigerant needs to flow between the compressor 123, the condenser, and the evaporator, and therefore, the compressor 123, the condenser, and the evaporator need to be connected by pipes. Alternatively, the tubing may be copper tubing.
The air conditioner of this embodiment employs all the technical solutions of the air conditioner outdoor unit 100 in the foregoing embodiments, so that at least all the beneficial effects brought by the technical solutions of the foregoing embodiments are achieved, and details are not repeated herein.
So far, the technical solutions of the present invention have been described in connection with the preferred embodiments shown in the drawings, but it is apparent to those skilled in the art that the scope of the present invention is not limited to these specific embodiments. Equivalent changes or substitutions can be made on the related technical characteristics by those skilled in the art without departing from the principle of the invention, and the technical scheme after the changes or substitutions can be within the protection scope of the invention.
