Statistics show that the current domestic about 2 billion 150 million square meters of large buildings using central air conditioning, many of which have been faced with the renewal of the situation. At the same time, with the continuous increase in the rate of 2 billion square meters per year of new buildings, as well as urbanization, urbanization, promote the transformation of smart city, the new demand for central air conditioning is also significantly improved. We judge that the central air-conditioning consumer demand in the next few years will be much higher than the growth rate of domestic air conditioning. From the analysis of the use of domestic central air-conditioning, there are two main factors: one is the traditional central air conditioning energy consumption is huge, according to statistics, the total power consumption of a large building, air conditioning system of power consumption in an average of more than 50, and the current national energy-saving emission reduction requirements do not match; the two is the traditional central air-conditioning maintenance and the higher maintenance costs, greater economic pressure brought by the unit, the overall market needs of central air-conditioning manufacturers to launch low energy consumption, easy installation, low maintenance cost, long service life of the products, the traditional central air conditioning, as a new technology revolution. In order to meet the needs of macroeconomic management policy and to facilitate the production of enterprises accurately grasp the development trend of the overall market, the latest to understand the changes of market competition, making new year overall planning, marketing strategy, market information at the state information center wrote "report" the transformation of the traditional central air conditioning Chinese upgrade in 2013. The basic situation of the domestic central air-conditioning building in the city since the report on the 12th Five-Year implementation plan is analyzed, involving energy analysis, noise analysis, comfort analysis, age analysis, analysis of the status quo at home and abroad analysis of the effect of a series of content, according to the basic trend of the whole macro economy, the basic situation of domestic 2014 frozen annual central air conditioning market forecast analysis. Hope that the report to the macro management departments and production enterprises to correctly grasp the market trends, adjust the distribution strategy, do a good job in 2014 frozen annual development plan to help. The research on consumption, the traditional central air conditioning and energy-saving air conditioning energy in existing noise levels, the degree of comfort and service life, both at home and abroad, analysis of 6 aspects of effect analysis to conduct a comprehensive investigation, understand the present situation of the central air-conditioning, central air conditioning and analysis of the current problems and opinions to provide reasonable suggestions for construction of city building the. According to the Ministry of finance, Ministry of housing issued the "China urban development report," "on further promoting public building energy conservation work notice" and "green building program" instructions. With the acceleration of urbanization in our country, the implementation of energy conservation and green building will become the focus of building energy conservation and emission reduction. China urban development report pointed out that by 2020, there will be 50 of the population living in cities, by 2050 this proportion will increase to 75. Now, China's building energy consumption accounts for nearly 1/3 of the total energy consumption of the society, and the rapid urbanization led to a large increase in per capita energy consumption, China's building energy efficiency is facing great challenges. The "Circular" on further promoting the public building energy conservation work pointed out that nearly 40 City China has energy-saving pilot, in the next two years, the area of each energy-saving pilot city of not less than 4 million square meters; the market scale of public buildings energy-saving huge, even refined to the central air conditioning equipment modification, the annual scale will not less than 20 billion yuan. China has a total area of more than 43 billion square meters of construction, while the use of energy-efficient central air conditioning energy saving buildings less than 1. As of now, the total area of Chinese energy-saving building only 230 million square meters, while in an annual increase of nearly 2 billion square meters of construction area, the area and the number of green building is extremely limited, only accounted for 3 of all construction, that is to say there are 97 buildings are high-energy buildings. From the traditional central air conditioning and central air-conditioning energy saving in energy consumption, noise, comfort and service life at home and abroad, the comparison results and effect analysis can be found in our country, the traditional central air conditioning has brought great social energy consumption, if sustained elimination and does not limit the use of funds and personnel will bring more input. From April 15th, the Ministry of housing announced the "green building and green ecological city development plan" in 12th Five-Year, we can see that the country's energy-saving central air-conditioning will have a policy tilt, is conducive to the promotion and popularization of products. We can draw the conclusion that the energy saving central air conditioning can bring good environmental effect, and it will have a bright future in the future. The popularity of energy-saving central air conditioning will promote the implementation of green building and energy conservation reform in 12th Five-Year.
