Design precautions
1. In order to make the environment smooth and smooth, the system discharge volume = new air volume.
2. The volume of the building space: The breathing activity belt of the indoor person is 2.4m vertical height; the breathing activity zone of the people in the commercial building is a vertical height of 4.5m, and the volume ratio of the breathing belt occupies the entire space is about 0.26 ~ 0.47.
3. The new air volume of residential and office buildings is not less than 30m/h.p.Integrate the two factors of the number of air changes and the minimum new air volume, and take the larger new air volume as the basis for the selection.
4. Stadium, conference hall, theater, etc. can determine the new air volume selection based on the number of air replacements. If people stay less than 3 hours, the new air volume will be determined at the 50? seat rate.
5. For the central air -conditioning system space such as large shopping malls, select the new air volume according to 30%of the total air volume of the central air -conditioning system.
6. Factory and workshops, such as toxic and harmful substances distributing places, determine the new air volume according to the amount of air required for dilution concentration, and select the number of air conversion times.
Vancouver design requirements
1. To achieve lower wind resistance and noise of the design of the design, the new air output port and the host, between the exhaust output port and the host use the muffler or canvas soft connection.
2. For the ceiling machine, a springs must be installed on the boom or a rubber shock absorber.
3. When hidden in the room, the maintenance and maintenance port must be reserved.
4. The host and the main air tube should be kept 3 ~ 5 ° slope angle, and the host position should be slightly higher.
5. The metal duct must be kept insulation.
6. PVC pipes, rubber ripples, aluminum foil mink tubes, and aluminum foil composite tubes have the preservation performance and can be installed and used directly.
7. Installation of wind valves: The air volume regulating valve must be installed at the junction of the main air pipe and the branch pipe at the end of the proximal end, and the pipeline system can be used in the middle of the pipe system or the air volume regulating valve.
8. The air duct and the air duct should be connected with flange. The connection of flanges should be placed with rubber sealing.
9. Select the position of the air outlet: the opening of the air outlet should be uniform in principle to ensure that the fresh air volume and exhaust volume of each place in the room can be balanced.
10. The air inlet should not be opened in the following position: the turning point of the duct, the tail of the duct, and the variable diameter of the duct.
