Abstract

An air quality control for central air conditioning system consists of an air conditioning set, rooms, ventilating valves, fresh-air valves, an oxygen-producing unit, air-purifying unit, a transducer, and an oxygen detector. Air is treated to be suitable temperature and moisture, mixed with oxygen and then provided into rooms. The oxygen plants may be PSA, VSA, and VPSA pressure varied adsorbing plants and membrane separation style oxygen plants to produce 30 - 40% oxygen. The system can keep normal value of oxygen concentration in air of rooms, and reduce pollutants.

Description

technical field

[0001] The invention belongs to the field of environmental protection, and in particular relates to a control technology for regulating and controlling indoor air quality through a centralized air conditioner. Background technique

[0002] The quality of indoor air directly affects people's physical and mental health and work efficiency. Fresh air makes people feel refreshed, comfortable physically and mentally, not easy to get tired, and improves work efficiency. Unclean air not only endangers human health, but also causes damage to ecosystems and property losses. With the increasing popularity of air conditioners and the wide application of a large number of new building decoration materials, the indoor air pollution has further aggravated, and the problem of indoor air quality has become more prominent. From the perspective of energy saving, the airtightness of buildings using air-conditioning systems is getting better and better, although in some air-co...
