Clean air conditioning systems engineering construction quality and acceptance

First, the installation
1 air duct and accessories production
General provisions:
Divided by the working pressure to the duct system can be divided into three levels:
Low pressure system p ≤ 500Pa
Medium pressure system 500 <p ≤ 1500Pa
High pressure system p> 1500Pa
Pressure levels according to different classifications, duct materials, production and acceptance have different requirements.
Clean air duct system in the cleanliness of 6 to 9 of the system, belonging to medium pressure systems, OLED Display should be performed in the duct pressure system requirements, but for 1 to 5 clean air duct system should perform high-pressure system the wind tube requirements.
(2) the thickness of the metal duct
Master project:
Metal duct variety of materials, properties and thickness specifications should meet the design requirements and current national product standards.
3 air duct and air conditioning system parts made of metal duct production should meet the following requirements:
Master project:
1) Do not use cleaning sheet materials are hazardous to humans and cleaning agents; galvanized steel duct cleaning zinc coating shall not have serious damage phenomena,40x2 lcd such as surface white, zinc powder and so on.
2) the production of curved rectangular duct, generally should be used as a radius of curvature of the inner and outer concentric curved planar long elbow.
