Air conditioner as well as fresh air control method and device thereof

Abstract

The invention discloses an air conditioner as well as a fresh air control method and device thereof. The air conditioner comprises a heat exchange air duct and an air treatment device, wherein the airtreatment device comprises a casing, a fresh air fan and an air purification module; a fresh air inlet and a fresh air outlet are arranged on the casing; the air purification module is arranged in the casing to purify air entering the fresh air inlet; an air volume adjusting valve is arranged on the air treatment air duct. The method comprises the steps as follows: acquiring outdoor air indexes and judging whether the outdoor air indexes meet a preset fresh air quality requirement; if no, controlling the fresh air fan to be started, and controlling the opening angle of the air volume adjusting valve according to the current operation mode of the air conditioner. Thus, the introduced fresh air volume can be adjusted effectively while the indoor air quality can be improved, and the user experience is improved.

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.
