Air conditioner and controlling method and device thereof

Abstract

The invention discloses an air conditioner and a controlling 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 fan; and a fresh air inlet and a main air outlet are formed in the shell, and the fresh air fan guides air entering an air treatment air channel from the fresh airinlet into the main air outlet. The controlling method comprises the steps that when the air conditioner operates in a heating mode, if the indoor environment temperature is smaller than the first preset temperature and the outdoor environment temperature is smaller than the second preset temperature, the air conditioner is controlled to operate with the preset maximum heating capacity, and the fresh air fan is controlled to operate at the preset maximum rotary speed and guides the air entering from fresh air inlet into the main air outlet; and when the indoor environment temperature is largerthan the third preset temperature within the first preset time, the air conditioner is subjected to frequency-decreasing control, and the fresh air fan is controlled to operate at the preset rotary speed. Thus, when the indoor environment temperature is low, quick temperature rising and fresh air changing are achieved, 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 quickly heat up or cool down the air conditioner while heating or cooling, and ensure the quality of indoor air to meet the comfort and health needs of us...
