The company has experienced professional and technical personnel, specialized in various industrial and mining enterprises, hotels ventilation pipe installation, ventilation ducts schools, hospitals and other ventilation and exhaust gas treatment, waste dust collection of design and installation. Negative one to four shopping malls mechanical exhaust system, mechanical makeup air. Several shopping centers are set each smoke partition, the amount of smoke smoke partition area multiplied by the maximum 120m3 / h.m2 calculated air volume is calculated as 60-70% of the amount of smoke. Exhaust fan located in the building roof. Usually modular air conditioning units and fire up fans, air hose and outlet with the usual combination. Each smoke partitions are not normally closed leafy exhaust port. Hangzhou Xingda ventilation equipment to undertake all types of tin ventilation engineering, ventilation engineering Hangzhou tin tin factory, Shaoxing tin ventilation engineering, fume purification project in Hangzhou, Hangzhou, engineering, installation and design of ventilation, fire smoke hotel kitchen project, Hangzhou, central air conditioning duct installation and other train services. The company has experienced professional and technical personnel, specialized in various industrial and mining enterprises, hotels ventilation pipe installation, ventilation ducts schools, hospitals and other ventilation and exhaust gas treatment, waste dust collection of design and installation. Fan coil units should be carried out before entering the site acceptance, do stand-alone _ two-speed hydrostatic testing and commissioning. The test pressure of 1.5 times the system working pressure. Not leak in compliance. Horizontal unit should hanger fixed, and should be easy to disassemble and repair; drainage slope to meet the design requirements, the smooth flow of condensed water should flow to design the designated location for the return valve and water filtering, should be close to the fan coil units installation. Connection with the pipe fan coil should adopt a flexible tubing or soft takeover (metallic or non-metallic hose) connection, the pressure value should be higher than 1.5 times the working pressure of the hose connection should be solid and should not have a horse or deflated tube. Before the device factory fins should be cleaned of residual oil, or likely to cause condensation can not smoothly and have a "smoke" phenomenon discharged into the water tray.
