Fresh air purification of building ventilation purifier equipment, air conditioning and ventilation systems
In a closed indoor environment, the concentration of carbon dioxide is likely to rise. Due to the airtightness of modern buildings, air purifiers have become more and more densely populated and poorly ventilated indoors, where the carbon dioxide concentration exceeds the indoor air quality standard.
Carbon dioxide in indoor air generally does not reach very high toxic concentrations. In fact, the concentration of carbon dioxide in the indoor air of a household air purifier is often used to characterize the freshness of the indoor air or the amount of fresh air introduced during indoor ventilation. The carbon dioxide pollutants in indoor air mainly come from fuel combustion, gas exhaled by the human body and cigarette smoke.
Return air purification of building ventilation purifier equipment, air conditioning and ventilation systems
It is well known in the industry that in a closed room, the concentration of indoor air pollutants will be higher than outdoors. The amount of fresh air introduced by household air purifiers is limited by energy and is not enough to solve the problem of indoor air pollution. At this time, ventilation equipment, air conditioning, and return air purification devices of the ventilation system should be installed to process the circulating air.
Exhaust air purification of building ventilation equipment, air conditioning and ventilation systems
U.S. and other cities prohibit kitchen fume from being discharged into the atmosphere. my country’s catering industry also has strict kitchen oil fume emission standards, but they are limited to the catering industry, and there are no air purifiers to set standards for kitchen oil fume emission for thousands of households. In the future, my country’s exhaust air purification devices will receive environmental protection attention.
There is an obvious difference between the fresh air system currently promoted throughout the country and the popular foreign ventilating devices. That is, the intake air of the foreign ventilating devices of household air purifiers can be treated without treatment or simple treatment. The domestic fresh air system needs to be treated efficiently in many places. , In addition to particulate matter, but also gaseous pollutants must be dealt with. Exhaust gas is processed by foreign ventilation systems, but we haven’t heard of it yet.
