Indoor air quality control system

Abstract

The invention discloses an indoor air quality control system, and relate to the technical field of air purifying. Each user room is provided with a detection panel, an air outlet of each room is connected to the air inlet end of a circulation fan through an air outlet pipe, the air outlet end of the circulation fan is sequentially connected with a pm2.5 filter device, activated carbon, a negativeion humidifying device, an ultraviolet electric heating device and a carbon dioxide separation device, carbon dioxide inside the rooms is extracted out and exhausted out of the rooms, remaining treated air and high-concentration oxygen separated out by an outdoor oxygen separation device are fed into the rooms through an air inlet pipe, and the circulation fan, an air treatment function device, the carbon dioxide separation device, the oxygen separation device, intake air volume control valves, exhaust air volume control valves and the detection panels are connected to an intelligent air quality controller through a wireless network. The air quality is precisely controlled, the concentration of indoor oxygen and carbon dioxide is controlled in a qualified state, health is protected, the comfort level is improved, and energy is saved.

Description

technical field [0001] The invention relates to the technical field of air purification, in particular to an indoor air quality control system. Background technique [0002] The concentration of oxygen in the indoor air will decrease with the increase of the number of people and the activity time, but the concentration of carbon dioxide will increase, which will cause unqualified air quality and affect health. At present, ventilation (natural ventilation or mechanical ventilation) is generally used. , but improving indoor air quality through ventilation will cause a lot of energy loss, resulting in temperature difference and discomfort, poor comfort, and only qualitative operation is difficult to achieve accurate and timely control of ventilation. Based on this, a design for Indoor oxygen and carbon dioxide concentration air quality control system is particularly necessary. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the purpose of the ...
