Fresh air fan and air conditioner linkage system and control method and device thereof and storage medium

Abstract

The invention discloses a fresh air fan and air conditioner linkage system and a control method and device thereof and a storage medium. The system comprises a fresh air fan, an air conditioner, a detection device and a control device. The fresh air fan is integrated in an air conditioner indoor unit. The detection device and the control device are electrically connected. The detection device is used for detecting the cleanliness of indoor air. The fresh air fan comprises an air outlet, an air inlet, an air flue enabling the air inlet to communicate with the air outlet, a motor and a wind wheel. The control device controls the operation mode of the motor in the fresh air fan according to the cleanliness, detected by the detection device, of the indoor air. According to the scheme, when thedetected cleanliness of the indoor air is low, the motor is controlled to operate, a positive and negative pressure difference between the indoor environment and the outdoor environment is formed, outdoor fresh air is introduced into a room, or low-cleanliness air in the indoor air is extracted out to exchange with the outdoor air, the indoor air is fast purified, and the indoor air freshness isimproved.

Description

technical field [0001] The present invention mainly relates to the technical field of air conditioners, and in particular, relates to a linkage system between a fresh fan and an air conditioner, a control method, a device and a storage medium thereof. Background technique [0002] With the improvement of living standards, people pay more and more attention to air comfort. In some indoor environments, due to poor ventilation, the air quality in the indoor environment is not good, such as fine particles, inhalable particles, sulfur dioxide, The content of nitrogen dioxide, ozone and carbon monoxide is high, the air humidity is low, and the air quality is poor. In order to solve these problems, various types of air purifiers, humidifiers, etc. have appeared on the market, but a single air purifier can only purify the existing air in the room, and the purification depends on the filter screen, and the required purification time is long , and confined indoors, indoor air freshne...
