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 exchanging air channel and an air treatment device. The air treatment device comprises a shell and a fresh air draught fan. The fresh air draught fan is arranged in the shell. The shell is internally provided with an air treatment air channel which is isolated from the heat exchanging air channel, and the shell is provided with a fresh air inlet and a fresh air outlet. The control method comprises the following steps that indoor air indexes are acquired; whether the indoor air indexes meet a first preset condition or not is judged; if the indoor air indexes do not meet the first preset condition, the fresh air draught fan is controlled to be turned on, and the fresh air draught fan is not controlled to be in a ready state until the indoor air indexes meet a second preset condition. According to the method, whether the fresh air draught fan is controlled to be turned on or not is judged according to the indoor air indexes, in this way, when the indoor air quality is relatively poor, the air treatment air channel which is isolated from the heat exchanging air channel is used for introducing fresh air to improve the indoor air, and the user experience is 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...
