The liquid refrigerant with normal temperature and high pressure is gasified into low temperature gaseous refrigerant after reaching the indoor heat exchanger from the throttling element, so that the temperature of the indoor heat exchanger is reduced, the temperature of the gas flowing through the indoor heat exchanger is reduced, the low temperature gas is blown out by the fan, the temperature of the indoor air is reduced, and the air conditioner refrigeration is realized.

When the air conditioner is in the heating mode, the flowing directions of the refrigerant in the outdoor heat exchanger and the indoor heat exchanger are opposite to those of the refrigerant in the air conditioner in the cooling mode. The compressor compresses low-temperature low-pressure gaseous refrigerant into high-temperature high-pressure gaseous refrigerant, the high-temperature high-pressure gaseous refrigerant is conveyed to the indoor heat exchanger, the high-temperature high-pressure gaseous refrigerant becomes normal-temperature high-pressure liquid refrigerant after heat dissipation, a large amount of heat is released through liquefaction, the temperature of the indoor heat exchanger is increased, the temperature of gas flowing through the indoor heat exchanger is increased, the fan blows out high-temperature gas, the temperature of indoor air is increased, and heating of the air conditioner is achieved. The liquid refrigerant enters the outdoor heat exchanger through the throttling element, and the space is suddenly increased and the pressure is reduced after the liquid refrigerant reaches the outdoor heat exchanger from the throttling element at normal temperature and high pressure, so that the liquid refrigerant is gasified into low-temperature gaseous refrigerant, and a large amount of heat is absorbed by gasification, thereby reducing the temperature of the outdoor heat exchanger.

In this embodiment, the fan is a cross-flow fan, including an impeller, an air duct and a motor, and the impeller is generally made of aluminum alloy or engineering plastic. The aluminum alloy impeller has high strength, light weight and high temperature resistance, and can keep long-term stable operation without deformation.

After the water is added into the water tank 111, the water tank 111 enters the accommodating space through the inlet and outlet, and in the process of pushing into the accommodating space, the transmission device is triggered, so that the transmission device drives the pressurizing device 103 to fall inside the water tank 111. The water tank 111 can be pushed and pulled in the accommodating space inside the shell, so that the water can be conveniently and rapidly added into the water tank 111, and the structure is simple, and the manufacturing difficulty and the manufacturing cost are low.
