Air conditioner and dehumidification control method thereof

Abstract

The invention provides an air conditioner and a dehumidification control method thereof. The dehumidification control method comprises the steps of calculating environment dew point temperature according to environment temperature and environment humidity and confirming first target threshold value temperature range when the air conditioner is in a dehumidification mode; confirming first operationfrequency of a compressor according to detection temperature of a coil of an indoor heat exchanger; confirming second operation frequency of the compressor according to environment temperature; and controlling operation frequency of the compressor to be a larger one in the first operation frequency and the second first operation frequency. According to the air conditioner and the dehumidificationcontrol method thereof, as the environment dew point temperature changes, the temperature of the coil of the indoor heat exchanger is maintained in the first target threshold value temperature range,the temperature of the coil of the indoor heat exchanger is prevented from being higher than the environment dew point temperature, the situation that vapor in indoor air cannot condense into moisture is avoided, the indoor environment temperature is prevented from affecting frequency of the compressor when the air conditioner is in the dehumidification mode, the dehumidification effect is guaranteed, and dehumidification speed is increased.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to an air conditioner and a dehumidification control method thereof. Background technique [0002] At present, when the air conditioner is in dehumidification operation, the ambient dew point temperature of the indoor heat exchanger of the air conditioner is not fixed, especially when the air conditioner is in dehumidification operation, the ambient temperature and humidity of the indoor environment are changing. It will change with the process of dehumidification operation, and the evaporation temperature of the indoor heat exchanger will also change with the indoor and outdoor and the operating parameters of the air conditioner. When the evaporation temperature of the indoor heat exchanger is higher than the dew point temperature of the indoor environment, It will greatly reduce the speed of the dehumidification process and affect the dehumidification effect.
