Construction and installation of air conditioning system in purification engineering
The construction and installation of the air-conditioning system of the purification project includes: the production of the air duct system and its components, the installation of the air duct system, the installation of the air conditioner, the high-efficiency filter, and the installation of other air purification equipment and devices; There are reasonable construction procedures; horizontal joints are not allowed in the pipeline, and the longitudinal joint pages should be minimized. When the bottom edge is less than or equal to 800mm, no vertical joints are allowed on the bottom edge; all bite seams, flanges, rivets All parts must be coated with sealant; the four corners of the flange should be provided with screw holes, the distance between the holes should be less than 100mm, and the screws, nuts, gaskets, and rivets should be galvanized; Rinse with neutral cleaning solution, dry and seal with plastic wrap for installation.
It is only allowed to disassemble the sealing film of the pipe port during installation, and the port should be re-sealed when the installation pauses; various air duct components such as air valve and muffler must be installed to remove the oil and dust on the inner surface, which is not easy to apply Wipe the inner surface of the system many times with the material that has lost fibers; all kinds of gaskets, whether on the pipe flange or on various closed door frames, are strictly prohibited from painting the surface; after the system is installed, it should be checked for air leakage before insulation . When installing a high-efficiency air filter, it is the key to purify the air conditioning system and the construction and installation of the clean room. Before installation, the system should be cleaned by air blowing, and the clean room should be completely cleaned again. If the vacuum cleaner with filter bag is installed in the ceiling, the ceiling should be cleaned, and then the clean room can be cleaned again after the system is tested for 12 hours before the high-efficiency filter can be installed; the high-efficiency filter can only be unpacked at the installation site and at the time of installation. After taking it out, a visual inspection should be carried out, and a set of specific test data with performance indicators is required; all connected clean rooms are required to perform leak detection on the installed filters, and the key point of installation leak detection is the sealing quality of the filter frame; The resistance difference of each high-efficiency filter will affect the air volume balance and air flow uniformity. During installation, the individual filters with too high or too low resistance should be removed, and the filters with similar resistance should be installed in the same room. The filters should also be distributed evenly. Zhongjing Global can provide consulting, planning, design, construction, installation, renovation and other supporting services for purification projects and clean rooms.
The construction of the purification air-conditioning project should strictly abide by the relevant provisions of the construction acceptance specification, and correctly understand the requirements for the construction and installation of the purification air-conditioning system and equipment; the air outlet position of the high-efficiency filter screen should be designed to ensure that the working area is in the high-level cleanliness area; vertical In the form of one-way flow, attention should be paid to the installation position of the equipment so that the air flow cannot be blocked; the material for making the air duct should be a metal material with a smooth surface, no dust resistance, and resistance to disinfection gas corrosion. The surface layer of the equipment layer of the purification system cannot be equal to the ordinary equipment layer; the installation of the fresh air filter must first check the internal quality of the filter, and the leak detection should be carried out one by one at the installation site. The high-efficiency filter should be easily replaced in the future, and the filter paper and metal frame should not be easily touched. Before installing the high-efficiency filter, the air-conditioning system should be blown for more than 24 hours, and the clean area and equipment layer should be thoroughly cleaned.
