At present, our country's fresh air system is mainly used in home building, public building and industrial building in three areas. The reasons for the development of the new air system, a large part of the hospital, office buildings, banks and other public building market. Now with the development of the industry, under the government, enterprises and other common propaganda and promotion, family construction in the field of fresh air system needs to speed growth quickly, and the market demand is huge, more and more fresh air system has been in improving indoor air environment.

Indoor outdoor fresh air system is not expensive? An ordinary fresh air system, the price of only two ordinary air purifier. The effect of the air purifier is only to purify the air, and can not be outdoor fresh air into the room. And for the fresh air system, it can within 24 hours of the fresh air through the efficient purification into the interior, and the indoor dirty air is discharged to the outdoors, can simultaneously solve the haze, hypoxia, decoration pollution, odor, moisture and air problem, service life of up to more than 10 years, a common fresh air system can purification of several hundred square meters room.
Indoor fresh air system price, but also depends on your choice of what kind of fresh air system.

Indoor air pollution has been our urgent thing, the advantages of fresh air system is better than the air purifier, the two selected one, I believe we have the answer to it.
The calculation method of air volume in the domestic air system -- according to the requirement of the Ministry of housing "indoor air quality standard" per person per capita, 30m3 new air volume per person per hour, fresh air quantity calculation example:
Hypothesis: a family residential area S=150 square meters, height H=3m, n = 5 members if calculated in accordance with the amount of fresh air required per person, is fresh air volume Q1=N*30m3/h=5*30m3/h=150m3/h. followed by calculating the other room, the volume of fresh air, will obtain digital is the sum of the whole house air total amount.
The calculation method of air volume in the fresh air system: according to the calculation of the number of fresh air in the room according to the number of air changes, the number of fresh air ventilation P=1 (/h), the amount of fresh air Q2=P*S*H=1*150*3=450m3/h.
Due to Q2>Q1, the equipment selection of Q1, so the equipment selection based on Q2.
The above is about the calculation method of the air volume of the fresh air system, hoping to help you. Indoor air pollution needs us to pay attention to it, because the living environment of the family, is a direct impact on the health of the body.
