Xuzhou Sheng Erda Refrigeration Electrical Services Limited five, air conditioning, refrigeration, heating principle: endothermic evaporation, condensation heat. When freon gas refrigerant pressurized by the compressor, into the high pressure condenser, is condensed into a liquid heat Xuzhou air conditioning maintenance, reduced pressure in the liquid freon throttling device into the low pressure evaporator, the evaporator for the gas while extracting heat from the indoor, so as to achieve the purpose of cooling. Heating and cooling runs contrary, when the compressor produces the reverse cycle heating refrigeration cycle. Is also considered running air conditioning, hot wind from the outdoor to indoor air conditioner absorbed. Heating principle is that the air conditioner refrigerant in the atmosphere absorb calories (ie solar) as a heat source to warm the room. This is an excellent performance, efficient manner. It is only used to drive electric motors, electric furnace is to make a direct energy, air conditioners only about one-third of its electricity, and therefore economical, safe and clean. Even at low outdoor temperatures, the air conditioners can also take the heat from the atmosphere. The secret lies in the superior characteristics of the refrigerant, heating operation when the outdoor air conditioner freon within about -40 ℃, the temperature is very low, assuming that the outdoor temperature is 5 ℃, the temperature difference between the two is still a great phone Xuzhou central air conditioning repair, refrigerant can absorb the heat of the part, which was sent to the room. Xuzhou 圣尔达 Refrigeration Electrical Services Ltd 2, meaning domestic air conditioning symbols: as Model: KF (R) - 23GW, KC-23, KF-50LW Xuzhou conditioning repair, K representative on behalf of split air-conditioning F R representative and well-being C represents the bars of windows after the figures represent the people as righteous cooling capacity: 23 representatives of cooling capacity of 2300W, L on behalf of indoor floor-G on behalf of indoor hook, W on behalf of the outdoor unit. Third, the air conditioning horses adapt to a small area corresponding to the number 1P (23): 10-16 square meters (large) 1P (26): 12-18 square meters 1.5P (35): 16-24 square meters 2P (50): 23-34 square 3P (72): 32-50 square meters 5P (120): 55-85 square meters in Xuzhou, air conditioning repair, Sheng Erda refrigeration (certified), air conditioning provided by Xuzhou 圣尔达 Refrigeration Electrical Services Limited. Xuzhou Sheng Erda Refrigeration Electrical Services Limited (xzktw.com) Xuzhou, Jiangsu, heat, refrigeration and air conditioning equipment leader, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customers needs.
