Control method and device for condensation prevention of air conditioner and air conditioner

Abstract

The invention provides a control method and device for condensation prevention of an air conditioner and the air conditioner, and relates to the technical field of air conditioners. The control methodfor condensation prevention of the air conditioner comprises the steps that when the air conditioner is in a zero-wind-sense mode, the indoor moisture content is obtained; if the moisture content islarger than a first preset value, the indoor dew point temperature and the inner disc temperature are obtained; whether a difference value of the indoor dew point temperature and the inner disc temperature is larger than or equal to a second preset value or not is judged; if yes, whether the difference value of the indoor dew point temperature and the inner disc temperature is larger than or equalto a third preset value or not is judged, if yes, whether the upper limit frequency of a compressor is smaller than or equal to a difference value of the maximum frequency of the compressor and a fourth preset value or not is judged, and if yes, the upper limit frequency of the compressor is controlled to be increased; and if the difference value of the indoor dew point temperature and the innerdisc temperature is smaller than the second preset value, the rotating speed of an inner fan is controlled to be increased by a fifth preset value. By means of the control method, the probability of condensation generation of an indoor unit can be reduced while the user experience is improved.

Description

technical field [0001] The present invention relates to the technical field of air conditioners, in particular to an air conditioner anti-condensation control method, device and air conditioner. Background technique [0002] In high temperature weather, when the air conditioner is turned on indoors, due to the large temperature difference between indoor and outdoor, when the cold wind blows directly, the pores of the human body shrink and the body temperature drops. uncomfortable. The existing air conditioner has added a zero-wind function, which prevents cold wind from blowing directly by adjusting the angle of the inner and outer air guide doors. [0003] However, due to the adjustment of the angle of the inner and outer air guide doors, the air outlet area of ​​the air conditioner indoor unit is reduced, and the outlet air temperature is lowered, which is more likely to cause condensation on the indoor unit in a high temperature and high humidity environment.
