 Air-conditioning number of horses choice - Chongqing Li Xiang Electrical Appliance Sales Co., Ltd. to buy air conditioning cooling capacity output (heat) to correspond with the use of space, the use of room status and geographical differences in climate air conditioning, as well as plans for extreme weather, buy air-conditioning should buy large do not buy small. There are many factors that can affect the air conditioning system of air conditioning refrigeration temperature effect reasons, the most important floor, western exposure, west window, size and other items, then how accurate calculation of room air-conditioning power required size? First, the required cooling capacity per square meter set to 150W; if the top layer, which accounted for a western exposure, calculated per square meter 200W; if Xichuang or both top and western exposure, at least 250W per square meter; and they both Xichuang is the top, at least 300W per square meter; only more, no less air conditioning disease, or fixed speed machine downtime or frequency machine running at full speed until the protection start, resulting in room air temperature can not be adjusted; area selection room area in the table below applicable air conditioning Size (cooling) 10M2 the following 23 machines (small one) 10M2-14M2 26 machine (big one) 14M2-18M2 32 machine (small one and a half) 16M2-20M2 35 machines (plus a half) 20M2-32M2 50 machine (n two horses) 30M2-45M2 61 aircraft (two horses and a half) 45M2-55M2 75 machine (junior match) air conditioning quality certification mark - Chongqing Li Xiang Electrical Appliance Sales Co., Ltd.

CECC mark: Europe electrician certification mark. Consumers in the purchase of air-conditioning products, in addition to choose according to the brand, performance, specifications, etc., various quality certification mark also can be used as a reference. Air conditioning knowledge - Chongqing Li Xiang Electrical Appliance Sales Co., Ltd. Air Conditioning namely air conditioning (air conditioning), refers to the use of artificial means, for the building / structure of the ambient air temperature, humidity, cleanliness, speed and other parameters can be adjusted and controlled process . Typically includes several major and other auxiliary equipment cold source / heat equipment, hot and cold media distribution system, terminal devices. Including pumps, fans and piping systems. Terminal devices are responsible for the use of transmission and distribution to the cold heat, specifically the process air, the air parameters to meet the requirements of the target environment. The initial development of refrigerant, refrigerators use of toxic gas, ammonia, chloride and the like. It will lead to a major accident such gas leakage. Thomas 米基利 invented the chlorofluorocarbon gases (chlorofluorocarbon gas) in 1928, and name Freon. This refrigerant is much safer for humans, but harmful to the ozone layer. Freon is a trademark of DuPont CFC, HCFC or HFC type refrigerant, wherein the refrigerant in each category name further includes a number indicating the molecular composition of its components (e.g., R-11, R-12, R-22, R- 134). Where the air conditioning frequency and fixed frequency difference, in the direct evaporative cooling product areas moderately most widely R-22 HCFC refrigerants will cease production of equipment for the new 2010, and in 2020 completely stopped using. R-11 and R-12 in the United States has been discontinued. As an alternative, some of the ozone-friendly refrigerants have been put into use, including the trade name "Puron" refrigerant R-410A. R290 and R32 new environmentally friendly refrigerant gradually move toward the market, R290 molecules containing only carbon and hydrogen, containing no chlorine and fluorine, ozone-depleting potential (ODP) of zero.
