Air conditioning system control method

Abstract

The invention discloses an air conditioning system control method. The relative humidity in an indoor unit can be reduced within the set time to destroy the breeding and living environment of bacteria and mildew, and mildew prevention and sterilization in the indoor unit are achieved. A control unit of an air conditioning system can execute a mildew-proof operation mode, in the air conditioning system control method, the mildew-proof operation mode comprises an in-machine dehumidification stage, and in the in-machine dehumidification stage, when preset conditions are met, the control unit controls the air conditioning system to start a dehumidification process for reducing relative humidity. The dehumidification process comprises air supply operation of blowing air in the indoor unit into a room, and through the in-machine dehumidification stage, within a specified time, the ratio of the relative humidity in the indoor unit to the relative humidity before the in-machine dehumidification stage is reduced to be within a preset range capable of destroying the breeding and living environment of the bacteria and mildew.

Description

technical field [0001] The invention relates to an air-conditioning system control method, in particular to an air-conditioning system control method for inhibiting the growth and reproduction of bacteria and reducing the growth of mold. Background technique [0002] As we all know, after the air conditioner is used for a long time, there will be dust attached to the interior of the indoor unit, especially the indoor heat exchanger, and the dust provides sufficient nutrients for the growth of bacteria. In addition, after cooling operation or dehumidification operation, the humidity inside the indoor unit increases, which provides an excellent environment for bacteria to multiply. [0003] Bacteria growth, multiplication, or even mildew inside the indoor unit will cause the air blown into the room to seriously endanger the health of users. If the mold inside the indoor unit grows seriously, it may even block the pores (air outlet path) inside the indoor unit, reducing the ai...

Problems solved by technology

[0024] However, both patent document 1 and patent document 2 can only realize the cleaning and drying of the indoor heat exchanger, and do not affect the internal environment of the indoor unit (especially temperature and relative humidity), so that the inside of the indoor unit cannot be completely anti-mildew and sterilized, that is, it does not destroy the breeding and living environment of bacteria and mold, and can only be cleaned once.

[0025] In addition, especially in Patent Document 2, the heating operation is performed immediately after the cooling, and the temperature difference of the air blown out from the air outlet is large, which makes the indoor occupants feel less comfortable and does not save energy.
