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, a fresh air fan and an air purification module. The shell is provided with a fresh air inlet, an indoor air inlet and a main air outlet. The fresh air fan guides air of an air treatment air flue to the main air outlet. The air purification module carries out purification treatment on air of the air treatment air flue. The method comprises the steps that indoor air indexes are acquired in real time; whether indoor air quality is superior to outdoor air quality or not is judged according to the indoor air indexes; if the outdoor air quality is superior to the indoor air quality, the fresh air fan is controlled to guide air entering the air treatment air flue from the fresh air inlet to the main air outlet; and if the indoor air quality is superior to the outdoor air quality, the fresh air fan is controlled to guide air entering the air treatment air flue from the indoor air inlet to the main air outlet. Thus, the efficiency of improving indoor air can be improved, and user experience can be improved.

Description

technical field [0001] The invention relates to the 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 gradually becom...
