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 includes a heat exchanging air channel and an air processing device. The air processing device includes a shell and a fresh air fan. The fresh air fan is arranged in the shell. An air processing air channel which is mutually isolated from the heat exchanging air channel is arranged in the shell. A fresh air inlet and a ventilation opening are formed in the shell. The heat exchanging air channel communicates with the air processing air channel through the ventilation opening. The fresh air fan guides air which enters the air processing air channel from the fresh air inlet to the heat exchanging air channel through the ventilation opening. The controlling method comprises the followingsteps that when the air conditioner runs in a heating mode, the ventilation opening is controlled to be opened in order to make the air which enters the air processing air channel from the fresh airinlet be mixed with air conditioning air of the heat exchanging air channel when the indoor ambient temperature is greater than the first preset temperature and the outdoor environment temperature isless than the second preset temperature. In this way, introduced outdoor fresh air can be heated up firstly and then exhausted into a room, and 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 and meet the user's comfort requirements while the air conditioner is heating or cooling has gradually become a...
