It is understood that the central air-conditioning energy consumption of building energy consumption in developed countries account for about half of total building energy consumption to 35% of the calculation, the proportion of central air conditioning energy consumption of the total energy consumption of about 17.5%. Of existing buildings with a total area exceeded 43 billion square meters, but so far only energy-efficient buildings with a total area 230 million square meters, the use of energy-efficient central air-conditioning energy-efficient buildings is less than 1%. An annual increase of about 2 billion square meters of buildings, there is news that the proportion of green buildings 3% down. China Energy Conservation Association of Energy Service special committee said that the current large public buildings accounted for about 5 percent, or 2.15 billion square meters, more than ordinary screw machine, centrifuge and other traditional central air conditioning system. If the unit can be replaced with energy-saving, national saving each cooling season is expected to more than 16 billion of Xi'an central air conditioning, energy equivalent to a fifth of the Three Gorges power plant generating capacity, or 13 million tons of coal produced. Harmonious relationship between the environment and human being closely watched by more and more countries and regions, whether developed or developing countries, are currently working on improving the living environment. Wherein Xi'an central air-conditioning manufacturers, focusing on energy-saving central air-conditioning popularization and application is an important part. From promoting foreign experience can be drawn, energy-efficient central air conditioning can bring a good environmental effects, help promote the "five-second" green building and energy-saving implementation, has a more broad prospects for development in the future. Winter temperatures gradually decreased so that everyone in the family quilts, coats and other warm clothing handy. For many homes, "are old and small," the public, choose a suitable cold appliances, it is very urgent. Several years ago, people still hot air conditioning heating function should not join, and shortly, we are no longer satisfied simply air-conditioning cooling and heating function, and more and more manufacturers to join a new technology to enrich the air-conditioning products Xi'an features central air-conditioning agents, the results brought about by the pace and intelligent air conditioning. Choose a heating and air conditioning in the winter is a very good choice. "Buy air conditioning when not only consider the cooling area, higher power should buy air-conditioning, in order to ensure the heating effect in winter. During use, the best choice for low-speed wind and level down, so the system better thermal effects. "Shanghai Group altar experts advise general Xi'an central air conditioning supply, 1P heating hang the heating area of ??10-11 square meters; 1.5P hang heating area of ??17-23 square meters; 2P heating Guiji the heating area 20-22 square meters; 2.5P Guiji heating area of ??24-28 square meters; 3P Guiji heating area of ??27-30 square meters. In addition to dry weather in autumn and winter, when the air conditioning in the selection should pay attention to whether they have moisturizing function, which allows the indoor temperature more comfortable.
