Mildew-proof drying control method for HEPA filter screen full-coverage air conditioner

Abstract

The invention provides a mildew-proof drying control method for an HEPA filter screen full-coverage air conditioner, the mildew-proof drying control method comprises the following steps that S0, the air conditioner is operated; S1, the air relative humidity RH of an HEPA filter screen is detected, a first air relative humidity threshold RH1 is set, if RH is larger than or equal to RH1, S2 is executed, and otherwise S0 is executed; and / or the operation time of the air conditioner is t0, the set operation time is t1, if remote control shutdown is conducted and the operation time t0 is larger than or equal to t1, S2 is executed, and otherwise S0 is executed; S2, the air conditioner stops a refrigeration or dehumidification mode, a drying indicator light is turned on, a mildew-proof drying mode is started until RH is smaller than RH1, S3 is executed, and otherwise S2 is executed; and S3, the mildew-proof drying mode is stopped, the drying indicator light is turned off, and S0 is executed. According to the mildew-proof drying control method, condensed water and water vapor in an evaporator and the filter screen area can be dried, the humidity of the area is reduced, mildew on the filter screen can be effectively inhibited, the service life of the filter screen is prolonged, and the healthy use experience of a user is improved.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a method for controlling mold prevention and drying of an air conditioner fully covered by a HEPA filter. Background technique [0002] With the rapid development of society, the air quality is getting worse and worse, and the function of air purification has become more and more important. However, few air conditioner indoor units with purification function on the market have full-coverage air inlets to purify the air. In the prior art, the indoor unit generally has the function of purifying a local area or cleaning the filter screen. [0003] However, in the prior art, it is difficult to prevent bacteria and dust in the air from entering the indoor environment with the circulation of the wind. The bacteria and dust entering will cause poor air purification effect of the indoor unit and seriously affect the health of users. Moreover, the air resistance of the HEPA filt...

Problems solved by technology

[0003] However, the existing technology is difficult to prevent bacteria and dust in the air from entering the indoor environment with the circulation of the wind. The bacteria and dust entering will cause poor air purification effect of the indoor unit and seriously affect the health of users.

Moreover, the air resistance of the HEPA filter is large, and the condensed water of the evaporator will dry naturally for a long time when the machine is turned off, which is easy to breed mold. How to prevent mildew has also become a key issue
