Many places in life need to use fresh air air -changing machine fresh air air -changing machines can be said to be a major helper in life.What you need to know now is the type and choice of fresh air replacement machines.
1. According to the air volume of the fresh air airway, select
Before choosing the air volume of the fresh air aircraft, we must first 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 you send 280 cubic meters of fresh air every hour and discharge 280 cubic meters of indoor turbid air together, it is said that the number of air changes in this room reaches once.
There are two ways to account for air volume. One is to calculate according to the area of ??the construction space, and the other is to calculate according to the person in the applicable place.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 occupations, such as the hospitals operating room, special care unit, laboratory, factory workshop, etc., to confirm the new air volume required in accordance with the relevant standard requirements.
2. Select the new fan according to the construction situation.Fresh air gas exchanges are divided into one -way flow, full thermal communication, and pipeline -type fresh air categories. Among these types, the equipment of the fresh air system is complicated, and the height and format of the house are required.Even if you need to wear beams to perfuse, if the house cannot meet the equipment requirements, it will not be able to equip the full heat to communicate with the fresh air system. You can only choose a relatively simple one -way flow and pipeline new style.
In addition, the demand for the new air system equipment is synchronized with decoration. If the house is now decorated and the equipment is required, the equipment can only be equipped with a new air system.
