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 accounting for about 5% of the central air conditioning Which is good, that is, 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 kWh, equivalent to one fifth of the energy 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. Among them, the focus on energy-saving central air-conditioning popularization and application is an important part. From promoting foreign experience can be drawn central air conditioning installation, energy-efficient central air conditioning can bring a good environmental effects, helps promote the "five-second" green building and energy-saving implementation, has a more broad prospects for development in the future . With home central air conditioning market competition increasingly fierce, product development reflects the more humane, diversification trend. Home central air-conditioning in technology continue to make new breakthroughs, prices are getting close to the people of central air-conditioning manufacturers, which also led to further adoption of home central air conditioning. In the Government to speed up the process of urbanization, the real estate market continued to pick up as well as growing demand for hardcover housing market background, the future of home central air conditioning will continue to show growth, and will be to boost domestic central air-conditioning market continues to grow Troika one.
