The fresh air air change machine is a new type of indoor ventilation equipment. Many people have not touched it in the past. The fresh air gas exchange machine is installed in different occasions.It is necessary to adopt different selection standards.
The use of public places requires a large amount of air volume. The number of air changes is generally calculated by 3-5 times per hour. Family uses fresh air air-changing machines. Due to the small number of people, the number of air replacements is generally calculated at 1 per hour.
Before selecting the air volume of the fresh air, you must figure out what is the number of air changes.Suppose the area of ??a room is 100 square meters and the height is 2.8 meters.The volume of this house is 280 cubic meters.If we send 280 cubic meters of fresh air outdoors per hour, and at the same time, 280 cubic meters of indoor turbid air is discharged, we will say that the number of air changes in this room reaches once.
There are two ways to account for air volume. They are calculated according to the construction space area, and the heads of the applicable place are calculated.
The new air volume required for each person is calculated by 30 cubic meters per hour.The number of air conversion times in public places is generally calculated by 3-5 times per hour.Regarding special industries, such as hospital operating rooms, special care ward, laboratory, factory workshop, etc., to determine the new air volume in accordance with relevant regulations.
