Detailed Product Description: | Air-conditioned building in the summer rely refrigerator indoor heat loads moved outdoors. Clearly, reducing the indoor heat load, reducing the running time of the refrigerator, central air-conditioning system energy consumption is reduced. Indoor thermal load from two aspects, one is the heat caused by the indoor and outdoor temperature exchange, on the other hand is the heat load generated by indoor lighting and equipment. Therefore, you can take the sun, air tightness, insulation and other measures to reduce indoor heat load to save energy. Reduce indoor heat load (1) reducing direct sun radiation sun roof, walls, windows and through the window into the room, can be cornice, visor (canopy), coated glass; reduce the external walls, roof absorb solar radiation heat Xuzhou central air conditioning repair, air conditioning can be light-colored exterior finishes, heat-insulating layer disposed on the outer walls and roof roof, roofing or overhead. Increase external shading for summer cooling load (or cooling capacity) to reduce very significantly. According to the China Academy of Building Research determination whitewashed cement roof, the roof surface temperature in summer can be reduced 16-19 ℃. (2) improve airtight airtight doors and windows, to prevent the gap into the wind. Use airtight plastic doors and windows not only good, but great resistance, and reduce noise Xuzhou Hisense air conditioning maintenance, reducing dust. Or the use of doors and windows sealed, airtight doors and windows to improve. Room air changes from 8 to 5 times, the consumption can be reduced by cooling the buildings around 8%. Therefore, the design should be used in well sealed doors and windows. Plus set up a closed bar is an important means to improve the air tightness of windows and doors. Depending on the circumstances of windows and doors, were different seal. Such as rubber, plastic or rubber strip binding seal. (3) the use of insulation materials for thermal insulation walls, roofs, doors, windows, etc. insulation, such as rock wool, slag wool, glass wool, polystyrene foam, expanded perlite, aerated concrete, rigid polyurethane foam, PVC plastic doors and windows hollow glass so as to reduce the heat transfer coefficient of building envelope. Hollow brick, two-story windows, etc., the use of air insulation, thermal insulation may also play a role. Additional external walls and roof insulation for winter and summer energy-saving benefit. How to identify the effect of circulating water treatment system of the three hazards are scaling, corrosion, microbial algae, to identify the effect of water treatment services is based on the merits carry out these three aspects. "Industrial circulating cooling water treatment design specifications" (GB50050-95) gives several indicators: 1 open systems fouling resistance value:. 1.72 × 10-4-3.44 × 10-4m2K / W2 closed system. soil thermal resistance less than:. 0.86 × 10-4m2K / W3 corrosion rate of carbon steel pipe wall is less than 0.125mm / a4 copper, copper alloy and stainless steel corrosion rate is less than the wall 0.005 mm / a5 open recirculating cooling water systems. heterotrophic bacteria count of less than 5 × 105 个 / ml; slime less than 4ml / m3 circulating water system by water quality analysis report regularly given Xuzhou hand air conditioning recovery, according to water quality and water treatment chemicals throughout the dosing different, there is a corresponding reference index, the user can initially determine the treatment effect according to water quality analysis reports, and can use of coolant water bubble sheet test and chilled water, cooling water way coupons site monitoring. Xuzhou air conditioning maintenance of telephone, air conditioning, refrigeration provided by Xuzhou Sheng Erda 圣尔达 Refrigeration Electrical Services Limited. Xuzhou 圣尔达 Refrigeration Electrical Services Limited (xzktw.com) strong, credible, Xuzhou in Jiangsu Province of heat, refrigeration and air conditioning equipment industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead Sheng Erda refrigeration into the brilliant and you work for a better future! |
