Embodiment Construction
[0061] see in conjunction figure 1 As shown, according to the embodiment of the present application, an air conditioner indoor unit includes: a housing 1, an air duct, a first heat exchanger 4 and an air supply mechanism 3, the air duct is located inside the housing 1; the first heat exchanger 4 is set in the air duct; the air supply mechanism 3 supplies air through the air duct, and the flow direction of the air in the air duct when it flows through the first heat exchanger 4 is opposite to the flow direction of the refrigerant in the first heat exchanger 4, which can simultaneously realize In the cooling and heating modes of the internal unit heat exchanger, the flow direction of the refrigerant and the flow direction of the air form a countercurrent, thereby improving the heat exchange efficiency of the heat exchanger.
[0062] Further, the first heat exchanger 4 includes an outer row heat exchanger and an inner row heat exchanger that communicate with each other; the outer...

The invention provides an air conditioner inner unit. The air conditioner inner unit comprises a shell, an air flue, a first heat exchanger and an air supply mechanism. The air flue is located in theshell. The first heat exchanger is arranged in the air flue. The air supply mechanism supplies air through the air flue, the flowing direction of air, flowing through the first heat exchanger, in theair flue is opposite to that of a refrigerant in the first heat exchanger, the reverse flow can be formed in the flowing direction of the refrigerant and the flowing direction of the air by an inner unit heat exchanger under the refrigeration and heating modes at the same time, and accordingly the heat exchange efficiency of the heat exchangers is improved. According to the air conditioner inner unit, the reverse flow can be formed in the flowing direction of the refrigerant and the flowing direction of the air by the inner unit heat exchanger under the refrigeration and heating modes at the same time, and accordingly the heat exchange efficiency of the heat exchangers is improved.
Description
technical field [0001] The application belongs to the technical field of air conditioners, and in particular relates to an air conditioner inner unit, an air conditioner and a control method. Background technique [0002] At present, the use of cylindrical cabinet air conditioners in the market is becoming more and more common. The indoor unit heat exchanger of the cylindrical cabinet air conditioner usually adopts a cylindrical heat exchanger and is arranged vertically. In the cooling mode, the indoor heat exchanger is used as an evaporator, and the low-temperature and low-pressure refrigerant after throttling is discharged in the evaporator. Evaporation absorbs heat and provides cooling. When operating in heating mode, the indoor heat exchanger acts as a condenser, and the high-temperature and high-pressure gaseous working medium discharged from the compressor flows into the condenser after being reversed by the four-way valve, and then condenses and releases heat to prov...
