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 processing device. The air processing devicecomprises a shell and a fresh air draught fan, the fresh air draught fan is arranged in the shell, and an air processing air channel separated with the heat exchanging air channel is arranged in the shell. A fresh air inlet and a ventilation port are formed in the shell, the heat exchanging air channel communicates with the air processing air channel through the ventilation port, and the fresh airdraught fan guides the air entering the air processing air channel from the fresh air inlet to the heat exchanging air channel through the ventilation port. The control method comprises the followingsteps that when the air conditioner works in a refrigeration mode, and the indoor environmental temperature is lower than a first preset temperature, and the outdoor environmental temperature is higher than a second preset temperature, the ventilation port is controlled to be opened so that the air entering the air processing air channel from the fresh air inlet is mixed with the air conditioningair of the heat exchanging air channel. In this way, the introduced outdoor fresh air can be cooled firstly, and then exhausted into a room, and the user experience is improved.

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...
