Condensation prevention method for air conditioner

Abstract

The invention belongs to the technical field of air conditioner control, and particularly relates to a condensation prevention method for an air conditioner. The method comprises the steps that the dew point temperature Td and the target evaporation temperature Tr corresponding to the indoor air are calculated according to the indoor temperature t and the room humidity f, the difference between the actual evaporation temperature and the target evaporation temperature is obtained, and different control objects are selected to conduct control according to the absolute value of the deviation. According to the condensation prevention method for the air conditioner, the evaporation temperature is controlled to prevent or reduce condensate water generated by the air conditioner, the condensation phenomenon of the air conditioner is improved, and water blowing of the air conditioner is prevented; the control means can be selected correspondingly according to the deviation between the actual evaporation temperature and the target evaporation temperature; when the deviation is large, the frequency of a compressor is adjusted to control the evaporation temperature so as to achieve rapid adjustment; and when the deviation is very small, the opening degree of an electronic expansion valve is adjusted to control the evaporation temperature so as to achieve the accurate control.

Description

technical field [0001] The present application belongs to the technical field of air conditioner control, and in particular relates to an air conditioner anti-condensation method. Background technique [0002] With the improvement of people's living standards, people's requirements for the comfort of the indoor environment are also increasing. In the hot summer, as the ambient temperature continues to increase, air conditioners have become an indispensable electrical In order to improve the heat dissipation capacity of human skin and make people feel cool and comfortable, dehumidification and dehumidification treatment are generally carried out. During this process, the moisture in the indoor air will be extracted. A large amount of water is discharged from the human skin and the respiratory cycle, and the water vapor will form condensation in the water of the air conditioner, that is, on the surface of the fins, and develop into water film droplets, which not only brings in...

[0002] With the improvement of people's living standards, people's requirements for the comfort of the indoor environment are also increasing. In the hot summer, as the ambient temperature continues to increase, air conditioners have become an indispensable electrical In order to improve the heat dissipation capacity of human skin and make people feel cool and comfortable, dehumidification and dehumidification treatment are generally carried out. During this process, the moisture in the indoor air will be extracted. A large amount of water is discharged from the human skin and the respiratory cycle, and the water vapor will form condensation in the water of the air conditioner, that is, on the surface of the fins, and develop into water film droplets, which not only brings inconvenience to the use of the air conditioner, but also affects the appearance of equipment and buildings It shows that when the air conditioner has serious condensation, it may cause the hidden danger of water leakage or blowing of the air conditioner, causing great trouble to users

At present, measures to improve condensation in air conditioners are mainly to paste thermal insulation materials on the structure to prevent condensation, and there are relatively few measures to prevent condensation from control means
