Air-conditioned building in the summer rely refrigerator indoor heat loads moved outdoors. Clearly, reducing the heat load Xuzhou indoor installation of central air conditioning, refrigerator running time is reduced, power consumption is reduced central air-conditioning system. 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 , can be light-colored exterior finishes, heat-insulating layer is provided on the outside 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. The use of plastic doors and windows not only air tightness, and large thermal resistance, and reduce noise and 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 and windows adiabatic central air conditioning, such as rock wool, slag wool, glass wool, polystyrene foam, expanded perlite, aerated concrete, rigid polyurethane foam, PVC plastic doors and windows, insulating 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 central air-conditioning maintenance of favorable Xuzhou central air conditioning prices, experts recommend that you do the following two points in the home central air conditioning maintenance aspects: First, the transformation of central air conditioning in Xuzhou, proper use and operation home central air conditioning units, regular maintenance, useful for extending the service life, we recommend at least two years testing and maintenance should be done once. Secondly, in front of the home central air conditioning maintenance host convert warm up for 24 hours. When cleaning the air conditioner condenser and evaporator coil can be directly hosed, if there are no conditions can also be used dry soft brush, brush the dust filter online, be sure to pay attention to the horizontal direction when cleaning cleaning, to avoid collision fin bad coil.
