 Buy air principle - Chongqing Li Xiang Electrical Appliance Sales Co., Ltd. to purchase the amount of room air-conditioning is a big consumer of household appliances, if the selected power is too small, no effect; if too much power, and waste. So when consumers select air conditioning power, the amount of room you want to buy. First, do not do too big, some consumers prefer to buy a large air-conditioning, which is not desirable, because in addition to a number of special factors, home air conditioning has its use. When consumers buy according to their own air-conditioned room area to select the model, generally according to the following formula to calculate the amount of room needed for refrigeration, heating capacity. Refrigeration room area × 140W to 180W; heating capacity room area × 180W to 240W. It should also make appropriate changes in accordance with the orientation, floor level and degree of sealing rooms. The second is to design the case according to the air-conditioned rooms, flexible purchase. Some families do not like it, buy a large air conditioning in the living room, to preserve the room, so not only difficult to preserve the room, but also wasteful. A reasonable approach is to be based on room type, buy low-power air conditioning, each tube each room.

So than only to buy three large air conditioning in the living room to be reasonable. The market size of the cooling capacity of the cooling capacity of the air conditioner should be W (watt) is represented on the market used to describe matching the size of the air conditioner cooling capacity. 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 . Most typically include several cold source and other auxiliary equipment / heat source equipment air conditioning is not cooling because, 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 appropriate in the direct evaporative cooling products in the field of the most widely used refrigerant R-22 HCFC production will be stopped for the new equipment in 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. Central air conditioning optional method - Chongqing Li Xiang Electrical Appliance Sales Co., Ltd. 5, heating. Under normal conditions, the single-user residential speaking, is not recommended for heating and air conditioning together.
