Air-conditioner and control method and device thereof

Abstract

The invention discloses an air-conditioner and a control method and device thereof. The air-conditioner comprises a heat exchange air flue and an air treatment device, the air treatment device comprises a shell and a fresh air draught fan, and the fresh air draught fan guides air entering an air treatment air flue from a fresh air inlet to a ventilation opening. The method comprises the steps that when the indoor air index does not meet a first preset condition and the outdoor air index meets a third preset condition, or when the indoor air index meets the first preset condition, the indoor air humidity is smaller than the first preset humidity, and the outdoor air humidity is larger than the second preset humidity, the fresh air draught fan is controlled to be started; when the temperature of air at the fresh air inlet is lower than the first preset temperature, the ventilation opening is controlled to be opened to enable air-conditioner air of the heat exchange air flue to be mixed until the indoor air index meets a second preset condition; and if the indoor air humidity does not reach the second preset humidity, the air-conditioner is subject to frequency-reducing control, the indoor air can be accordingly improved, and the user experience is improved.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to an air conditioner control method, an air conditioner control device and an air conditioner. Background technique [0002] With the development of science and technology and the improvement of people's living standards, people are increasingly pursuing a smart and healthy lifestyle. Traditional air conditioners that only have heating and cooling (including dehumidification) functions have gradually failed to meet the needs of users. Moreover, most traditional air conditioners use a closed air circulation system. Long-term closed air circulation is easy to breed bacteria, which will affect the user's healthy life to a certain extent. For example, it may cause symptoms such as colds and air-conditioning diseases. Therefore, how to ensure the quality of indoor air while the air conditioner is heating or cooling, so as to meet the comfort and health needs of users, has gradu...
