Large-scale promotion of geothermal heat pump Beijing installed 18 million square

Introduction

Ground source heat pump technology is currently the world's most advanced heating refrigeration and new technologies. It leverages the shallow geothermal heating room temperature refrigeration problems cannot be solved, belong to renewable energy technologies. Last 10 years worldwide each year to increase the speed of 20 percent, the growth to the end of 2005, there were 33 countries in promoting this technology. It has three main advantages: one is energy-efficient than other conventional heating technologies can save energy by 50-60 per cent; the second is environmental protection does not discharge any waste; third, the low operating cost, reduces 30-70%. Is heating refrigeration solve pollution energy saving important technology choices.

China heat pump from technologies to promote large-scale, developed more than ten years ' time. In recent years, energy shortages, prices, country strongly supported the development of ground source heat pumps, and a policy to give a certain concessions. In 1997 the Ministry of science and technology of China and the United States Department of energy cooperation agreement signed by the Government to develop and promote the ground source heat pump technology. As the Protocol of the Chinese side execution unit Beijing Jike ground source heat pump technology co., Ltd. in the United States Department of energy of the Chinese Ministry of science and direct guidance and assistance from the United States, introduced the most advanced ground source heat pump technology, combined with China's climatic, hydrological, geological and economic level, lifestyle, innovation and system optimization, developed a series for the Chinese market of heating refrigeration and heat pump systems technology, heating cooling effect in line with national standards. So far, ground source heat pump technology has become the heating refrigeration areas of renewable energy, energy, environmental protection, heating costs low main technical means.

First, the policy environment

Ground source heat pump technology since the last century as the "eleventh five-year" scientific and technical key project, from the United States since the introduction in the Ministry of science and technology, Ministry of construction, national development and Reform Commission, Ministry of finance, as the State encourages the promotion of energy saving and environmental protection technologies include various promotional programs, from the funds, taxation, loans, subsidies and other positions to policy support. In August 2007, the Ministry of finance and national development and Reform Commission issued the energy conservation technical innovation of the financial reward capital management procedures require enterprises to 1 ton per energy saving standard coal 200 central financial incentives — $ 250, including building energy efficiency projects. Local Government also introduced the appropriate policies to promote energy-saving emission reduction technology. As the Beijing Municipal Government from 2006 on the use of ground source heat pump heating engineering every building square one-time subsidies 50, users can enjoy time tariff preferential price Valley.

Second, main areas, the development of ground source heat pump

Beijing

Beijing installed 1800 square meters, the eleventh five-year period of 600 000 square meters installed, 2010 installation to 35 million square meters. 2008 Beijing Olympic Games Stadium "bird's nest" using ground source heat pumps, absorption of energy from the soil, for compensation Stadium air conditioning system, etc. Ground source heat pump is the use of renewable energy, energy saving, environmental protection systems, by ground heat exchanger tubes, winter absorption of calories contained in the soil as the "bird's nest" heating, summer in memory of soil absorption cooling capacity to "nest" cooling.

According to statistics, the Beijing Olympic Games has 358 "Green Olympics" projects, including new energy projects 69, building energy efficiency project 168 items, water resource projects in 121 items. The construction of Olympic projects a total of nine solar hot water system. 4 project a ground source heat pumps, three project-building a water source heat pump, there are two items directly using the geothermal.

200 million square meters of Olympic projects, 26.7 percent of the area will be the use of renewable energy and green energy. 168 building energy efficiency projects to conserve energy, the equivalent of $ 20 million tons of carbon dioxide emissions.
