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 duct and an air treatment device. The air treatment device comprises a housing, a fresh air fan and an air purifying module; a fresh air inlet and a fresh air outlet are formed in the housing, and the air purifying module is arranged in the housing to purify air entering the fresh air inlet. The method comprises the following steps of: acquiring indoor and outdoor air indexes and indoor and outdoor air humidity; controlling the fresh air fan to start when the indoor air index does not meet a first preset condition or 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 greater the second preset humidity, and controlling the air purifying module to start when the outdoor air index does not meet the third preset condition till the indoor air index meets the second preset condition; and performing frequency-lowering control on the air conditioner when the indoor air humidity does not reach the second preset humidity. Therefore, the indoor air can be improved and the user experience is enhanced.

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...
