Purification air conditioning construction process:
1. The production and installation of air ducts and accessories for purifying air-conditioning systems shall comply with the high-pressure air duct system (air cleanliness Nl ~ No clean room) and the medium pressure air duct system (air cleanliness N6 ~ N9 clean room) related requirements. Air duct production and cleaning should be selected with a weatherproof awning and a relatively closed, dust-free and clean enclosure.
2. When the side length of the rectangular duct is less than or equal to 900mm, the bottom panel shall not be spliced; the rectangular ducts larger than 900mm shall not be used for horizontal splicing; the duct system with cleanliness class N1～N5 shall not adopt snap-on mouthpiece . The inner surface of the air duct is flat and smooth, and no reinforcement frame or reinforcement ribs shall be provided in the air duct.
3. The gap between the air duct and the component should be sealed with sealant; after the air duct is cleaned by clean water for cleaning requirements, the end of the air duct should be sealed in time and stored in a clean room, and dust should be avoided. Moisture and deformation.
4. The installation of the air duct of the clean air conditioning system shall be carried out under the condition that the ground of the installation part has been completed and the indoors are provided with dustproof measures. The airtight pipe and accessories that have been cleaned and sealed shall be connected and installed immediately after opening the sealing film of the port; when the installation is to be suspended, the port shall be resealed.
5. The sealing treatment of the connection to the air outlet, all kinds of end devices and various types of pipelines and the clean indoor surface should be reliable and strict; the air conditioning unit, static pressure box, air duct and air return air outlet should be clean and free of dust.
6. The assembled air handling unit on site shall be tested for air leakage after installation. The air leakage rate of the unit used in the air cleanliness class N1～N5 clean room (zone) shall not exceed 0.6%, and the N6～N9 class shall not exceed 1. O%.
7. The high-efficiency air filter should be completed and accepted in the clean room (area) building decoration and piping construction. The clean room (zone) has been thoroughly cleaned and cleaned, and the air-conditioning system has been cleaned and continuously tested. More than 12h can be installed. After the high-efficiency filter has passed the visual inspection, the frame, filter paper: sealant, etc. are free from deformation, breakage, breakage, shedding, etc., and should be installed immediately. The installation direction must be correct; the connection with the air duct, air duct and equipment should be reliably sealed; the perimeter of the filter and the interface should be tight; the air supply with high efficiency air filter should be fixed.
