The Market Value of Upgrading Central Air Conditioner May Reach RMB 200 Billion

Date:2013-7-22 16:31:28

In China, central air conditioning history less than 20 years. 90 time metaphase, installation of central air-conditioning of the building began to appear in a large number of domestic central air conditioning, these now seems mostly belongs to the non energy saving products. According to the calculation of central air-conditioning use fixed number of year, just need to update the current. High efficiency energy-saving products share the urgent need to improve "in China, central air conditioning history less than 20 years. 90 time metaphase, installation of central air-conditioning of the building began to appear in a large number of domestic central air conditioning, these now seems mostly belongs to the non energy saving products. According to the calculation of central air-conditioning use fixed number of year, just need to update the current." The personage inside course of study has revealed. Relevant data shows, up to 2011, our country public construction area of about 2000000000 square meters, if all the alternative use of magnetic energy saving central air conditioning, calculated in accordance with the construction costs per square metre 120 yuan, the replacement market cake will be as high as 200000000000 yuan. It is understood, the State Ministry of housing and urban rural development recently published "Twelfth Five Year" development planning of green building and green ecological city, put forward the goal of green building development planning of the 12th Five Year Plan, this will also give the central air-conditioning energy saving opportunities. Commercial central air-conditioning is "high energy consumption" China Academy of building research building environment and Energy Research Institute president Xu Wei said, if large public buildings are high energy consumption of the big city, then, HVAC is building energy consumption. In developed countries, HVAC energy consumption accounted for 65% of building energy consumption, building energy consumption accounted for the total energy consumption to 35.6% computing, HVAC energy consumption ratio of the total energy consumption can be as high as 22.75%. It is understood, the so-called HVAC, including household use large central air conditioning and small independent air conditioning, the energy consumption of large central air conditioning, particularly attract sb.'s attention. The survey data of the state information center market information display, by analyzing the current domestic use of central air-conditioning, there are two main restricting factors: one is the traditional central air-conditioning energy consumption of the great, according to statistics, the total power consumption of a large building, air conditioning system power consumption accounts for the proportion is more than 50%, with the current national energy saving the emission reduction requirements do not match; the two is the traditional central air-conditioning maintenance, repair cost is higher, economic pressure to bring the use of units, the overall market need central air-conditioning manufacturing enterprises to launch low energy consumption, convenient installation, repair and maintenance of low cost, long service life of the product, the traditional central air conditioning, no less than a new technical revolution. The survey data from Beijing Institute of refrigeration display, in Beijing public buildings with central air conditioning, power consumption of the building consumption accounted for 35% of the city's buildings. Central air conditioning has proposed maglev good energy saving transformation "Twelfth Five Year Plan of green building and building green ecological city development planning", to carry out energy-saving reconstruction of existing buildings, "Twelfth Five Year Plan" period, the completion of the North heating area has a more square meters heating metering and energy-saving 400000000 flat residential building, hot in summer and cold in winter and hot summer and warm winter area existing residential 50000000 square meters of building energy saving, public building energy saving reconstruction 60000000 square meters, with dilapidated houses in rural areas the implementation of rural energy efficiency demonstration of 400000 residential units. At present, China's total area of office buildings and commercial real estate is 1200000000 square meters, if all the alternative use of magnetic energy saving central air conditioning, a year can save cooling / heating electricity 32200000000 degrees, equivalent to 1/3 of Three Gorges power station power generation quantity. In addition, the traditional central air conditioning host noise at 85 decibels, is extremely easy to damage the engine room staff hearing long, and in the energy-saving air-conditioning to Maglev central air conditioning as the representative, operation without oil technology can make the main noise less than 70 decibels, will not damage the hearing room office staff. It is reported, the traditional central air conditioning of the provisions of the state, the service life is 15 years, in the main parts under the condition of normal use, usually in the use of 5 years or so after the failure of the peak, the entire life cycle maintenance costs nearly 400000 yuan; in the energy-saving products to Maglev central air conditioning as the representative, because between the bearing operation without friction, the service life of up to 25 years, while the non oil system also reduces the replacement of equipment repair costs, such as midway, save a lot of expenditure. A shows the actual application Haier maglev central air conditioning project case, although the initial investment in the selection of magnetic products is high, but the use of two and a half years to recover the investment cost of the early.
