[Tianjin Jinzhong Ji HVAC purification equipment to recommend the star product - Ventilation pipeline project] working conditions 1, the installation of refrigeration room works in general ventilation systems and air conditioning systems, to be completed in the building envelope construction, obstacles clean-up project has been under the ground conditions and free of debris. 2, the installation of the air cleaning system should be installed inside the building on the ground of good parts, plaster walls have been finished ventilation pipe project, 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] turbulence turbulence cleanroom cleanroom main features are never out of the air flow between the flow (from the air port to the return air) stream flow cross section is varied, the clean room is much larger cross-section than the outlet cross section, and thus can not cross section in the whole room or work area in the whole cross-section chamber formed uniform airflow. Therefore, after the outlet of the flow lines are provided in a large or increasing the angle, the radius of curvature is small, the air can not flow in one direction in the room, will impact against each other, there will be refluxed, vortices. This determines the turbulent flow regime is the essence of clean room: mutation flow; non-uniform flow. This is more precise than the turbulent flow clean room to describe the chaos, more comprehensive. Mainly determined by the Reynolds number turbulence, which is mainly affected by the flow rate, but if an efficient air filter top form sent, even if the flow rate is extremely low clean plant engineering, but also to produce the above results, which since It is a mutation flow and non-uniform flow. Therefore, this case is not only due to turbulent flow mixing occurs between the stratosphere, but also blended the whole range of big room reflux, vortex occurred.
