Abstract

The invention relates to an indoor positive and negative pressure control system. At least one indoor air inlet fan and at least one indoor exhaust fan are arranged indoors, a corresponding exhaust port is formed in indoor space where the indoor air inlet fan is located, the indoor air inlet fan is used for guiding outdoor air into the indoor space, and the indoor exhaust fan is used for guiding indoor air to outdoor space. The indoor positive and negative pressure control system further comprises an indoor air quality detection module and a control module, the indoor air quality detection module is arranged near the exhaust port, and the control module is used for controlling starting and shutdown of the indoor air inlet fan and the indoor exhaust fan according to data obtained by the indoor air quality detection module. By controlling the indoor air inlet amount and the indoor air outlet amount, the specific flow direction of indoor air is achieved, and mutual pollution of indoor pollutants is reduced.

Description

technical field [0001] The invention relates to an indoor positive and negative pressure control system. Background technique [0002] With the current rapid development of economy and industry, the air pollution in most parts of our country is becoming more and more serious. In addition to indoor formaldehyde and volatile gas pollution, which have been bothering for a long time, smog has become the focus of people's daily discussions. In smoggy weather, the air is filled with a large amount of inhalable particulate matter——PM10 and PM2.5 (PM10 and PM2.5 refer to fine particles with diameters less than or equal to 10 and 2.5 microns in the atmosphere). Among them, PM2.5 can directly invade the human bronchioles and lung cells, directly affect the ventilation function of the lungs, and make the body prone to hypoxia. Health is the number one priority. [0003] In the prior art, the scheme of positive and negative indoor pressure is adopted, and there is a positive and nega...
