Abstract

The air conditioner comprises an indoor unit and an outdoor unit, the indoor unit comprises an indoor heat exchanger set and a throttling assembly, the indoor heat exchanger set comprises a plurality of heat exchange units, and each heat exchange unit comprises at least one heat exchanger; the throttling assemblies are formed between the adjacent heat exchange units. Each throttling assembly comprises an electromagnetic valve and a capillary tube connected with the electromagnetic valve in parallel. The outdoor unit comprises a compressor, an outdoor heat exchanger and a four-way valve, when a non-cooling dehumidification mode is started, the electromagnetic valve is closed, a refrigerant circulates between the adjacent heat exchange units through capillary throttling, one heat exchange unit serves as an evaporator for heat absorption and dehumidification, the other heat exchange unit serves as a condenser for cooling and heating, and the non-cooling dehumidification effect is achieved; meanwhile, by controlling the rotating speed of the outdoor fan, the opening degree of the electronic expansion valve and the frequency of the compressor, the indoor temperature and humidity and the system stability are adjusted in time, and improvement of the comfort degree is facilitated.

Description

technical field [0001] The invention belongs to the technical field of air conditioners, and in particular, relates to an air conditioner. Background technique [0002] Air conditioners are household appliances commonly used in people's daily life. In the "rainy season" and "back to the south" weather in the south, the ambient temperature is low but the humidity is high. At this time, users have a strong demand for dehumidification. Conventional air conditioner dehumidification technology It is to make the air conditioner run in cooling mode, while the indoor unit fan is maintained at a lower gear. At this time, the indoor unit is an evaporator, and the air is cooled by the indoor heat exchanger to remove the water vapor in the air, so that the condensed water is precipitated after reaching the dew point, so as to achieve the purpose of dehumidification. Therefore, dehumidification must be accompanied by a temperature drop at the same time. . [0003] When the air conditio...
