[Tianjin Jinzhong Ji HVAC purification equipment to recommend the star product - ventilation pipework 1] working conditions, general exhaust system and install air conditioning systems, building envelope construction to be completed in the project quotation, obstacles have cleaning, no debris of the ground conditions. 2, the installation of air-cleaning system, and should be prepared to install components on the ground inside the building works, plastering walls have been completed, the room is not dusty or dust control measures under the conditions. 3, the general dust duct system should be installed in the plant process equipment or installing equipment base has been determined, the next device connector, cover position known manner. 4. Check the site reserved hole location, size should be consistent with requirements of the drawings, each side bigger than the actual section 100mm. 5, the job site have the appropriate facilities, such as ladders, shelves, security, fire-fighting equipment, and technical construction workers, quality and safety disclosure. [Tianjin Jinzhong Ji HVAC purification equipment to recommend the star product - decontamination] for parallel flow clean room, "said laminar flow clean room is customary), due mainly to air flow," Pistons beat the extruding lines exclude dye, So the speed of the cross-section is a very important indicator in the past have made reference to the United States 20gB standard refrigeration room works, using the 0.45m / s. But people also understand that such a large amount of ventilation required speed is great ventilation pipeline project, in order to energy conservation, are also in the quest to reduce the feasibility of wind. In China, the "clean air technical measures" and (clean plant design specifications) vertical parallel flow are such provisions (laminar) cleanroom ≥0.25m / s level parallel flow (laminar) cleanroom ≥0.35 m / s ventilation ducts engineering works _ _ Chongqing, Tianjin Jinzhong Ji Ventilation is provided by Tianjin Jinzhong Ji purification HVAC Equipment Co., Ltd., Tianjin Jinzhong Ji HVAC purification equipment (www.Jzjnt.com) strong, credible, in Tianjin fans, ventilation equipment industry has accumulated a large number of loyal customers.
