Problems solved by technology

[0002] At present, when the air conditioner is running in dehumidification, the ambient dew point temperature of the indoor heat exchanger of the air conditioner is not fixed, especially when the air conditioner is running in dehumidification, 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

Embodiment Construction

[0023] figure 1 It is a schematic block diagram of an air conditioner 10 according to an embodiment of the present invention. The air conditioner 10 of an embodiment of the present invention includes an indoor unit 100, and the indoor unit 100 includes an indoor heat exchanger 110 and an indoor fan 120. An embodiment of the present invention The air conditioner 10 of the example also includes a controller 200, and the controller 200 includes a processor 220 and a memory 210, wherein a control program 211 is stored in the memory 210, and the control program 211 is used to realize dehumidification of the air conditioner 10 when executed by the processor 220 Control Method. The controller 200 can control the rotation speed of the indoor fan 120 .

[0024] When the air conditioner 10 enters the dehumidification mode, the refrigerant in the indoor heat exchanger 110 of the air conditioner 10 evaporates and absorbs a large amount of heat, causing the surface temperature of the evap...

Abstract

The invention provides an air conditioner and a dehumidification control method thereof. The dehumidification control method of the air conditioner comprises the steps that the target threshold valuetemperature range is determined according to the environment dew point temperature, the air conditioner is controlled to be in a dehumidification mode, the coil pipe detection temperature is kept within the target threshold value temperature range by adjusting the rotation speed of an indoor fan of the air conditioner, and then the dehumidification speed of the air conditioner is increased. The environment dew point temperature changes along with changes of the environment temperature and the environment humidity, therefore, it is guaranteed that the coil pipe temperature of an indoor heat exchanger is kept within the target threshold value temperature range, the condition that the coil pipe temperature of the indoor heat exchanger is too high is avoided, and then the condition that watersteam in indoor air can not be condensed into water is avoided; and meanwhile, the indoor fan can have a high rotation speed to promote air flowing on the condition that the water steam in the indoorair can be condensed into the water, therefore, the dehumidification effect is guaranteed, and the 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.
