Embodiment Construction

[0020] Embodiments of the present invention are described in detail below, and the embodiments described with reference to the drawings are exemplary, and embodiments of the present invention are described in detail below.

[0021] The air conditioner performs a refrigeration cycle of the air conditioner by using a compressor, a condenser, an expansion valve, and an evaporator. The refrigeration cycle consists of a series of processes involving compression, condensation, expansion, and evaporation, and supplies refrigerant to air that has been conditioned and heat exchanged.

[0022] The compressor compresses 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 the heat is released to the surrounding environment through the condensation process.

[0023] The expansion valve expands the hig...

Abstract

The invention discloses a refrigerant circulation system, a method for controlling dehumidification of an air conditioner and the air conditioner. The refrigerant circulation system comprises a compressor, a reversing device, an outdoor heat exchanger, an indoor heat exchanger, a first electronic expansion valve, a flow dividing pipeline and a second electronic expansion valve, wherein the flow dividing pipeline is connected with the reversing device and the outdoor heat exchanger, and the second electronic expansion valve is arranged on the flow dividing pipeline; the indoor heat exchanger comprises a first indoor heat exchange unit, a second indoor heat exchange unit and a third electronic expansion valve, the first end of the first indoor heat exchange unit is connected with the first electronic expansion valve, and the second end of the first indoor heat exchange unit is connected with the first end of the second indoor heat exchange unit; and the second end of the second indoor heat exchange unit is connected with a fourth pipe opening of the reversing device, and the third electronic expansion valve is arranged between the first indoor heat exchange unit and the second indoor heat exchange unit. The refrigerant circulation system can provide a hardware basis for the air conditioner to realize various dehumidification modes, and is low in cost and wide in application range.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a refrigerant circulation system, a method for controlling the dehumidification of the air conditioner, and the air conditioner. Background technique [0002] At present, there are few air conditioners with the function of heating and dehumidification. If you want to realize the function of heating and dehumidification, you need to control the indoor electric heating to turn on or add a refrigerant device, and stop the outdoor fan. [0003] However, turning on the electric heating will lead to an increase in the cost of using the air conditioner, and adding a refrigerant device is not suitable for some air-conditioning products due to limited space or product cost, and the scope of application is small. Contents of the invention [0004] The present invention aims to solve at least one of the technical problems existing in the prior art. Therefore, the first object of...
