Question 2: How to divide the level of the air duct duct system according to its system of work constant force is divided into three categories, the classification of its category should be in line with the provisions of Table 4. 1. 5
According to the current development of ventilation and air conditioning engineering and technology needs and technical level of the air duct production
According to the current needs of the development of ventilation and air conditioning engineering technology and the technical level of air duct production, in the actual project, the different categories of air ducts can be differentiated according to the buyer's category for general ventilation, air conditioning and purification of air-conditioning systems.
Question 3: What is the meaning of ducted central air conditioning ah It is fan coil air conditioning, meaning that the indoor extension belongs to the fan coil.
The fan coil is actually a fan, the power with the size of the air volume.
Inside there are copper tubes that can go hot water and cold water
In winter time, hot water from the heating system director into the copper tubes inside the circulation, through the fan coil fan to blow out the warm air. In summer, cold water from the refrigeration system main into the copper pipe circulation, the same way refrigeration.
It can't produce heat or cold itself, but only the heat or cold produced by the host can be circulated for heating and cooling.

Question 4: What is the role of the air ducts in the building ah Classification of air ducts:
Air conditioning ducts: this does not need to be explained to the role of it. Fresh air duct: In order to office (or production) environment needs, to the indoor delivery of fresh air duct.
Exhaust duct: above the new air is for, this is back.
Fire exhaust pipe: to meet the fire code requirements, in the event of a fire, the smoke out of the outdoors.
Kitchen exhaust pipe: the smoke and vapor produced by the kitchen is discharged outdoors.
In addition, there are exhaust hoses for ventilation fans.
Question 5: What is this on the exhaust duct? 20 points muffler, the role is to control noise
Question 6: What is the purification duct? For example: clean plant, medical and surgical rooms Other than this are not applied!
Question 7: What is the pressurized air duct Pressurized air duct, you say this is not right, it should be pressurized air supply or positive pressure air supply called positive pressure air supply: set up in high-rise buildings for evacuation of smoke-proof stairwells. Because of the occurrence of fire personnel mainly through the stairwell down to escape, on the one hand, the smoke exhaust fan in the area of the fire smoke, on the other hand, because of the fire door of the barrier, so that the stairwell can temporarily form a relatively safe area, at the same time, the various floors of the air supply to the building inside the delivery of fresh air to ensure that the personnel to breathe enough.
Question 8: What is the meaning of the cross-sectional area of the duct If the duct is 2000mm * 500mm (width × height), the cross-sectional area is 2 * 0.5 = 1 square meters ah
Question 9: May I ask you: air conditioning (air duct machine), what is the difference between the ordinary duct and super duct? Please try to explain in detail! Ordinary air ducts are generally made of galvanized steel, air ducts for air conditioning need to be insulated, generally using closed-cell rubber and centrifugal glass wool is more.
Super ducts are generally made of dense centrifugal glass wool, which can provide insulation, reduce noise and other advantages.
Question 10: What is the super duct noncombustible super duct the product has passed the National Air Conditioning Equipment Quality Inspection Center, the National Fire Building Materials Quality Supervision and Inspection Center, the China Preventive Medical Sciences Institute of Environmental and Health Engineering, Shandong Provincial Technical Supervision and Inspection Bureau of the Department of testing, the indicators have reached the air conditioning and ventilation system specifications for the use of the requirements. Such products have been widely used in North America, and Western European countries. Introduced into our country in 1998, through the use of different units in Beijing, Shanghai, Tianjin, Shijiazhuang and other major cities, y praised by users. It is the ideal replacement of traditional air ducts in the field of ventilation in our country.
LBX non-combustible super duct system pipe plate using the original U.S. main plate, the main plate is equipped with male and female molded edges, so that after shaping the duct naturally form a socket interface, the pipe plate appearance is framed with durable fire-resistant aluminum foil, a cloth and paper, the inner surface of the specially formulated chemical latex thermo-solidified and become.
LBX non-combustible super ducts are mainly connected by socket type and special aluminum alloy flange.
