Dehumidification air conditioner and dehumidification method

Abstract

The invention provides a dehumidification air conditioner and a dehumidification method. The air conditioner comprises a compressor, a four-way valve, an outdoor heat exchanger, a first throttling device and an indoor heat exchanger, wherein the compressor, the four-way valve, the outdoor heat exchanger, the first throttling device and the indoor heat exchanger are connected in series through a refrigeration pipeline. The indoor heat exchanger comprises an evaporator and a recooler, wherein the evaporator and the recooler are connected in series, the recooler is adjacent to the first throttling device, and a second throttling device and a third throttling device connected in parallel are arranged between the evaporator and the recooler. In the dehumidification mode, when the indoor temperature is higher than the upper limit value of the set temperature, the air conditioner is set to be in the cooling and dehumidifying mode, and the indoor temperature is lowered simultaneously when dehumidifying is carried out; when the indoor temperature is lower than the lower limit value of the set temperature, the air conditioner is set to be in the heating and dehumidifying mode, and the indoor temperature is increased simultaneously when dehumidifying is carried out. The air conditioner enables the indoor temperature to be maintained with the range close to the set temperature value when carrying out dehumidification, and therefore a comfortable indoor environment can be realized.

Description

technical field [0001] The invention belongs to the technical field of air conditioning, and in particular relates to a dehumidification air conditioner and a dehumidification method. Background technique [0002] Air conditioners are generally composed of compressors, four-way reversing valves, outdoor heat exchangers, capillary tubes and indoor heat exchangers. [0003] Composed of components such as appliances, it can realize cooling and heating functions. Existing air conditioners have a dehumidification function, and there is no essential difference between the dehumidification and cooling operation modes. It is only to control the indoor fan at a slightly lower wind speed in the dehumidification operation mode than in the cooling operation mode or in an intermittent operation mode. to fulfill. In the dehumidification operation mode, the temperature of the room cannot be controlled, and low-temperature air supply will be generated, which will also reduce the room temp...
