For example, the installation of the complete full -hot fresh air exchange system has certain requirements for the height of the floor and the layout of the house, and sometimes it needs to be passed through the beam drill.Therefore, if the house cannot meet the installation requirements, the complete thermal exchange fresh air system cannot be installed. You can only choose simple one -way flow and pipeline installation.Secondly, the outdoor air volume must be considered.This is because the size and per capita traffic of each occasion are different.If the outdoor air volume is not appropriate, the air volume is too large or too small will affect the use effect.
1. Outdoor fan choice: according to the air volume of outdoor fan.
Before selecting the air volume of the new fan, we must first find out the number of ventilation.Assuming that the 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 outdoor air per hour and discharge 280 cubic meters of dark indoor air, we say that the number of air changes in this room has reached 1.
There are two calculation methods for air volume.One is calculated based on the area of ??the building space, and the other is calculated based on the head of the corresponding location.The fresh air required for each hour is 30 cubic meters.The number of air changes in public places is usually 3 times per hour.For special occupations, such as hospital operating rooms, intensive care rooms, laboratories, factory workshops, etc., the amount of fresh air required should be determined according to relevant standards and requirements.
2. Selection of new fan: Select the type of new fan according to the construction situation.
The new fan is divided into one -way flow through the pipeline, with full heat exchange and fresh air ventilation.Among these types, the installation of a complete heat exchange fresh air system is the most complicated, and there are certain requirements for the height and form of the house.Therefore, if the house cannot meet the installation requirements, the complete thermal exchange fresh air system cannot be installed. You can only choose simple one -way flow and fresh air. In addition, the installation requirements of fresh air systems are synchronized with decoration.If the house has been renovated and you still need to install fresh air, you can only install a split fresh air system.
With the continuous development and progress of fresh fan technology, the use of fresh fan technology has also developed widely.There are many types of new fan products, and different occasions and habits need different products.
