Control method and device of air conditioner and air conditioner

Abstract

The invention provides a control method and device of an air conditioner and the air conditioner. The control method of the air conditioner comprises the steps that in the condition that the air condition is in a refrigeration mode or a dehumidification mode, when the air conditioner is shut down or subjected to timing shutdown, the operation time of a compressor is detected; the operation time is compared with a first preset threshold and a second preset threshold; when the operation time is larger than the first preset threshold and smaller than or equal to the second preset threshold, the indoor environment temperature T1 and humidity RH and the temperature T2 of an evaporator coil are detected; the dew-point temperature T<dew> is calculated according to the indoor environment temperature T1 and humidity RH; whether the temperature T2 of the evaporator coil is smaller than the dew-point temperature T<dew> or not is judged; when the judgment result is yes, the air conditioner is controlled to start a drying and mould proof mode; and when the judgment result is no, the air conditioner is controlled to be shut down directly; and the first preset threshold is smaller than the second preset threshold. By means of the technical scheme, whether the drying and mould proof mode function is started is judged automatically, so that the air conditioner is more intelligent and humanized.

Description

technical field [0001] The present invention relates to the technical field of air conditioners, in particular, to an air conditioner control method and device, and also to an air conditioner. Background technique [0002] At present, after a household air conditioner is used for cooling or dehumidification for a long time, a lot of condensed water will hang on the evaporator of the internal unit. The humid environment in the air conditioner will lead to the growth of bacteria and produce peculiar smell. These molds or peculiar smell will contaminate the room with the opening of the air conditioner, thus affecting the health of users. At the same time, the long-term humid environment makes the evaporator more likely to accumulate dust and scale, resulting in dirty evaporator fins and attenuation of the air volume of the internal unit, resulting in poor heat transfer efficiency of the air conditioner, which seriously affects the comfort of users. . Therefore, household air ...
