Central air conditioning system requires a lot of energy central air conditioning, building energy consumption accounts for about 60% of the total energy consumption of central air conditioning Which is good, therefore requires air conditioning system needs to save energy central air conditioning installation, save operating input. The reasonable choice of insulation material thickness and product, as well as strict control of insulation construction is an effective way to energy-efficient central air-conditioning system. If the building renovation costs 2,500 yuan per square meter to 3,000 yuan calculated central air-conditioning manufacturers, public building energy efficiency market size of up to 50 trillion yuan. In the Department of Housing and the initially identified nearly 40 public buildings energy-saving major cities to major cities in the next two years each block public buildings energy-saving project area 4,000,000 square meters, market size of 4,000 billion yuan may be. The main aspects of building energy-saving are: to improve the external structure of the building, change welfare as household heating metering and charging, heating and heat energy saving, energy-saving air conditioning cold source, energy-saving heating pipe network, using the new heat source.
