Air conditioner and its humidity control method and device

Abstract

The invention discloses an air conditioner, and a method and a device for controlling the humidity of the air conditioner. The method includes steps of acquiring current indoor environment humidity when the air conditioner runs in a refrigeration mode; judging whether the current indoor environment humidity is within preset humidity ranges or not; judging whether throttling elements are available in the air conditioner or not if the current indoor environment humidity is not within the preset humidity ranges; acquiring current outdoor environment temperatures and current indoor environment temperatures if the throttling elements are available in the air conditioner and acquiring opening regulating variables for the throttling elements according to the current outdoor environment temperatures, the current indoor environment temperatures and the current indoor environment humidity; keeping current running frequencies of a compressor in the air conditioner unchanged under the control and regulating current opening of the throttling elements according to the opening regulating variables to allow the current indoor environment humidity to be within the preset humidity ranges. The air conditioner, the method and the device have the advantages that the opening of the throttling elements can be adjusted, accordingly, ratios of refrigeration latent heat to sensible heat of the air conditioner can be adjusted, the relative humidity of indoor air can be controlled, and the comfort of the indoor air can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to an air conditioner humidity control method, an air conditioner humidity control device and an air conditioner with the control device. Background technique [0002] Humidity, cleanliness and temperature are three important indicators to measure room comfort. Among these three important indicators, humidity is often ignored by the public, but in fact, humidity has a great impact on human health. [0003] In summer, the indoor and outdoor ambient temperature is high, and the relative humidity is often high. When the user turns on the cooling mode, since the surface temperature of the evaporator in the air conditioner is lower than the dew point temperature of the indoor air, the air conditioner will cool down during the cooling process. The moisture in the indoor air is condensed and precipitated, resulting in a decrease in the relative humidity of the indoor air, which in...

Problems solved by technology

[0003] In summer, the indoor and outdoor ambient temperature is high, and the relative humidity is often high. When the user turns on the cooling mode, since the surface temperature of the evaporator in the air conditioner is lower than the dew point temperature of the indoor air, the air conditioner will cool down during the cooling process. The moisture in the indoor air is condensed and precipitated, resulting in a decrease in the relative humidity of the indoor air, which in turn makes the indoor air dry

[0004] At present, in order to control the humidity of the room, users usually buy a humidifier to increase the relative humidity in the room, thereby improving the comfort of the room. meet higher requirements
