Currently released "Declaration of Central Air-conditioning Energy Saving," said lithium bromide absorption type, hot and cold water systems, variable frequency multi-line and other traditional central air-conditioning energy-saving, while high pollution May 20, Ningbo WFI Ground Source Heat Pump Central Air Conditioning Co., Ltd. Beijing released a high-profile "central air-conditioning energy-saving declaration." Declaration made - to solve the problem of high energy consumption of central air conditioning, change the way to provide energy, the use of renewable clean energy, is the fundamental strategy. The WFI ground source heat pump type of central air conditioning system is the most energy-efficient, environmentally friendly central air-conditioning on the market today, compared with the traditional central air conditioning, energy-saving up to 30% -50%, and will not cause pollution to the natural environment, it is worth promoting vigorously. A survey shows that the traditional central air conditioning is one of the major energy consumers, energy waste, environmental pollution problems prominent. Only Chongqing and Shanghai, for example, the central air conditioning electricity consumption accounted for 23% and 31.1% of the city's total electricity consumption. At the same time, traditional gas-fired air-conditioners and air-conditioners have large initial investment and high operating costs. Due to their own technical defects, they pose threats to nature and living environment. According to statistics, in 2006, the cost of using natural gas for heating in Beijing increased to 30 yuan / m2 in winter, much higher than the cost of 18 yuan / m2 for coal-fired heating and the fuel heating cost was even higher, reaching 50 yuan / m2. At the same time, the greenhouse gases produced by fuel and gas still pollute the atmosphere. Insiders pointed out that a few years ago, due to higher profit margins, the rapid development of China's central air conditioning market, lithium bromide absorption type, hot and cold water systems, variable frequency multi-line almost one-third of the world, the eight brands each occupy a stable share. For the issue of high energy consumption, the traditional brand is not indifferent attitude, but Ningbo WFI ground source heat pump air conditioning 嵇 Cheng-feng believes that the traditional high-energy central air conditioning is limited to its own technology and product structure constraints, the law appears to be wrong direction, So plunged into a "power-saving energy-saving" cycle. Behind the bustle, in fact, hide a huge market crisis. Aiken Information "2006 China Air Conditioner Cooling Industry Sales Analysis" shows that the market share of lithium bromide absorption air conditioning unit dropped sharply, only 7%, but the most important reason is that natural gas prices. It is understood that the ground source heat pump technology is a use of shallow underground geothermal resources and shallow water sources, both heating and cooling of high efficiency energy-saving air-conditioning system. Groundwater source heat pump to use geothermal energy or shallow layer year-round temperature stability characteristics of the ground in winter as a heat pump heat source, the higher than the ambient temperature in the energy out of the heat to supply indoor heating; the summer can be used as air-conditioning Of the cold source, the indoor heat removed to release below ground temperature in the energy. The principle is through a very small amount of energy transfer of energy to achieve the transfer. Industry experts point out that the water and soil on the surface of the earth is a huge solar collector, collecting 47% of the solar energy, more than 500 times the annual energy use of mankind. Water source heat pump technology is stored in the shallow surface of the near infinite renewable energy, to provide heating and air conditioning for people, deserved to become a form of renewable energy. After the source water passes through the heat pump unit, only the heat is exchanged and the water quality hardly changes. After being recharged to the formation or re-drained into the surface water, it will not cause pollution to the original water source. It can be said that the ground source heat pump is a clean energy approach. According to technical experts from WFI (China), traditional central air-conditioners need to be operated by refrigerants such as refrigerants. The conversion of energy to hot and cold requires not only consuming a large amount of energy such as electricity and water, but also affecting the surrounding environment during energy conversion Pollution. In addition, inevitable loss of energy conversion. Ground source heat pump central air-conditioning energy-saving because it will soil, water as a source of energy, only 50% of the energy consumption can be achieved to provide the same energy, under the same conditions, energy-saving than lithium bromide up to 70% , And in the product operation, because it does not use Freon, natural gas, gasoline and other refrigerants, will not cause secondary pollution of the environment.
