Xuzhou Sheng Erda Refrigeration Electrical Services Ltd., window air: usually installed in a window, installation and maintenance is relatively simple, the size is not restricted, the price is relatively cheap, but the window-type shape than a single machine, installed at an additional charge. 2, Wall split air conditioning: installation location limitations of small, easy and interior decoration with, easy to operate, nice. Split air conditioning with ultra-quiet operating characteristics air conditioning parts, will not affect sleep, and has multiple purification, but the price is more expensive than some window air-conditioning. 3, split cabinet air: cooling and heating power of strong winds and strong, suitable for large area room, shops, restaurants and public places. But take a place, big noise. 4, single-cooled air conditioning: non-heating function for the hotter summer or winter adequate heating supply areas. 5, air-conditioning: a heating function, according to its heating can be divided into heat pump and electric auxiliary heating type. Heat pump is suitable for hot summers and colder regions; electric auxiliary heating type because of the increased electric auxiliary heating element, heating strong, so is suitable for hot summers and cold winters in the region. 6, the day hanging, hidden ceiling air conditioning: basically a commercial machine series (2P-5P), currently brand: Sanyo, Daikin, Mitsubishi Electric, Haier, Hualing. Xuzhou Sheng Erda Refrigeration Electrical Services Limited five, air conditioning, refrigeration, heating principle: endothermic evaporation, condensation heat. When freon gas is pressurized refrigerant compressor, into the high pressure condenser, is condensed into a liquid heat, reduced pressure in liquid Freon enters the throttling device in the low pressure evaporator, the evaporation of the gas, and absorbs heat from the indoor, so as to achieve cooling purposes. Heating and cooling runs contrary, when the compressor produces the reverse cycle heating refrigeration cycle. Is also considered cooling operation, the air conditioner from the heat absorbed by the outdoor to the indoor wind. Heating principle is that the air conditioner refrigerant in the atmosphere absorb calories (ie solar) as a heat source Xuzhou plastic parts air conditioning parts, 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 freon heating operation when the outdoor air conditioning unit within about -40 ℃ Xuzhou air conditioning maintenance, the temperature is very low, it is assumed when the outdoor temperature is 5 ℃ Xuzhou conditioning parts trading, the temperature difference between the two is still great, The refrigerant can absorb the heat of the part, which was sent to the room.
