The invention provides an air conditioner. The air conditioner comprises a compressor, a four-way valve, an evaporator, an expansion valve, an electromagnetic valve, a condenser and a controller, wherein the compressor, the four-way valve, the evaporator, the expansion valve, the electromagnetic valve and the condenser are connected into a loop through pipelines, and the controller makes the air conditioner operate. The electromagnetic valve comprises a main electromagnetic valve capable of controlling the opening state and one or more supercooling electromagnetic valves arranged in parallel;an outlet of the supercooling electromagnetic valve is connected with an inlet of a supercooling heat regenerator; the outlet of the supercooling heat regenerator is connected with the inlet of the expansion valve; and the controller controls the working states of all the supercooling electromagnetic valves and the main electromagnetic valve according to a comparison result of temperature and humidity data received in real time and a preset value, operation of independent refrigeration, refrigeration and supercooling dehumidification is achieved, and a dehumidification amount is adjusted by controlling the opening number of the supercooling electromagnetic valves. The invention further provides a dehumidification method of the air conditioner. According to the air conditioner and the dehumidification method, a dehumidification effect and the dehumidification amount are adjusted by controlling a flow of a refrigerant flowing through the supercooling heat regenerator, and the dual effects of refrigeration and supercooling dehumidification are achieved.

    本发明提供了一种空调,包括通过管路连接成回路的压缩机、四通阀、蒸发器、膨胀阀、电磁阀、冷凝器以及控制空调运行的控制器,所述电磁阀包括可分别控制开启状态的主电磁阀和一个或多个并联设置的过冷电磁阀,所述过冷电磁阀的出口与过冷回热器的入口连接,所述过冷回热器的出口与所述膨胀阀的进口连接,所述控制器根据实时接收的温、湿度数据与预设值的比较结果,控制各所述过冷电磁阀及主电磁阀的工作状态,实现单独制冷、制冷加过冷除湿的操作,并通过控制过冷电磁阀开启数量进行除湿量的调整。本发明进一步提供了该空调的除湿方法。本发明提供的空调和除湿方法,通过控制流经过冷回热器的制冷剂流量实现除湿效果和除湿量的调节,实现制冷和过冷除湿的双重效果。
