Embodiment Construction

[0025] Preferred embodiments of the present invention are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present invention, and are not intended to limit the protection scope of the present invention. For example, although the relative humidity threshold is described as 85% in the drawings, the relative humidity threshold is not static, and those skilled in the art can adjust it as needed to adapt to specific applications. For example, in areas with high humidity, the relative humidity threshold can be set to 80% or 75%, and in relatively dry areas, the relative humidity threshold can be set to 90% or higher.

[0026] Generally, an air conditioner includes an indoor unit and an outdoor unit. The indoor unit is provided with an indoor heat exchanger, an indoor fan, etc., and the outdoor unit is provided with a compressor, an electronic expansi...

Abstract

The invention relates to the technical field of air conditioners, and particularly relates to a condensation preventing control method for an air conditioner. The invention aims to solve the problemsof high cost and bad effect of an existing condensation preventing control method for the air conditioner. In order to solve the problems, the condensation preventing control method comprises the steps of comparing an indoor humidity value with a relative humidity threshold during refrigeration of the air conditioner; calculating the ratio of a real-time current value of an indoor fan to a standard current value in the condition that the indoor humidity value is greater than the relative humidity threshold, and comparing the ratio with a set threshold; and selectively controlling the air conditioner to enter a condensation preventing mode according to the comparison result of the ratio and the set threshold, wherein the standard current value is preset. According to the control method, thecondensation preventing effect can be effectively increased, the condensation preventing cost of the air conditioner is reduced, and the use experience of a user is improved.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to an anti-condensation control method for an air conditioner. Background technique [0002] At present, air conditioners are widely used and have gradually become an indispensable household appliance for people in summer. When the air conditioner is running in the cooling mode, if it is in a harsh environment such as high temperature and high humidity for a long time, the coil temperature of the indoor heat exchanger will be far lower than the dew point temperature of the air. At this time, the indoor unit is prone to condensation problems , and then the air conditioner blows water or the indoor unit panel drips water, which greatly affects the user experience. [0003] In view of the above problems, the existing technical solutions usually judge the condensation degree of the indoor unit by the indoor temperature and the coil temperature of the indoor heat exchanger, and...
