Air conditioner and fresh air control method and device thereof

Abstract

The invention discloses an air conditioner and its fresh air control method and device. The air conditioner includes a heat exchange air channel and an air processing device. The air processing device includes a casing, a fresh air fan and an air purification module. The casing is provided with a fresh air Inlet and fresh air outlet, the air purification module is set in the shell to purify the air entering the fresh air inlet, and the air volume adjustment valve is installed on the air treatment duct. The method includes: obtaining the outdoor air index, and judging whether the outdoor air index meets the preset If the outdoor air index does not meet the preset fresh air quality requirements, the fresh air fan will be controlled to open, and the opening angle of the air volume adjustment valve will be controlled according to the current operating mode of the air conditioner. While improving the air quality, it realizes the effective adjustment of the fresh air volume introduced, which improves the user experience.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a fresh air control method for an air conditioner, a fresh air control device for an air conditioner, 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...

AI Technical Summary

Problems solved by technology

When introducing fresh air, the fresh air volume can be adjusted through the motor speed in combination with the indoor load, but a high-cost DC motor is required to achieve precise speed adjustment, and different motor speeds will lead to changes in indoor noise, especially at night. The noise brought by the high speed will directly affect the user's sleep. At the same time, this kind of gear adjustment is not user-friendly and cannot be linked with the air conditioner, which increases the user's operational burden.
