Ground source heat pump global development status on _asdgvsag

Ground source heat pump you can follow the history of SCHOTT to 1912 a patent, Switzerland and ground source heat pump real business applications are nearly ten years of history. Such as the United States, as of 1985 National 14,000 Mesa heat pump, which is installed in 1997 45,000 units installed so far, but the 400,000 annually to 10 per cent of the rate steady growth. In 1998 the United States commercial building ground source heat pump system has accounted for the total population of air conditioners 19%, with new buildings account for 30 per cent. United States ground source heat pump industry was established by the United States Department of energy, environmental protection Department, love Madison power Research Institute and many other ground-source heat pump manufacturers formed United States ground source heat pump Association, the Association in recent years will be invested US $ 100 million in the development, research and extension work.����United States plan to achieve annual 2001 40 million Mesa heat pump is installed, it will reduce greenhouse gas emissions 1 million tons, equivalent to a reduction of half a million car emissions or kind of tree-planting 1 million acres, the annual saving energy costs up to $ 4.2, thereafter, the annual energy costs increase 1.7 billion. Ground source heat pump of the development process, and the United States is different is that in Sweden, Nordic as, Switzerland, Austria, Germany and other countries mainly use shallow geothermal resources, underground soil buried pipes (depth < 400 m deep) of ground source heat pump, used to indoor floor heating and providing hot water.����According to a 1999 statistics for household heating appliances, the proportion of ground source heat pumps, Switzerland is 96%, 38%, Austria as a 27 per cent in Denmark. Ground source heat pump market development, the United States particularly optimistic about China 's, United States Department of energy and the Ministry of science and technology in November 1997, signed the Sino-u.s. energy efficiency and renewable energy cooperation protocol, which is one of the main content of the "heat pump", the project is intended to be used in China, Beijing, Hangzhou and Guangzhou 3 cities with the building of a geothermal heat pump for heating and air conditioning business architecture to promote the use of such "green technology", alleviate China coal and oil dependence, so as to achieve the aim of diversification of energy resources. Currently, the three ground-source heat pump demonstration project is being implemented, has entered the stage of implementation.����At the same time, the Chinese Ministry of science and technology enterprise Corporation commissioned brewing the United States of ground source heat pump technology and equipment for the introduction of the Chinese market, which will promote the commercialization of ground source heat pumps, industrial development, and make our research and development of ground source heat pumps as soon as possible to keep pace with international trends. China heat pump industry in recent years are beginning to start, but development momentum. Tianjin University, Tsinghua University partnershipswells fargo home equity loans with relevant Enterprise Learning Consortium developed the Chinese branHelp Desk Tracking Softwared of ground source heat pump system, has completed a number of demonstration projects, a growing number of Chinese users begin to familiarize yourself with the heat pump and application became interested in, you can expect the Chinese ground source heat pump market prospects. The reason for China's ground-source heat pump market Outlook optimistic, partly to save conventional energy, make full use of renewable energy in the domestic and international trends; on the other hand, China has good heat-pump based on scientific research and application, as early as the 1950s, Tianjin University of heat energy Institute Professor Lu-Chan on our eaDesk Help Software Trackingrliest heat pump, 1965, developed the first water-cooled heat pump air conditioner. Chongqing jianzhu University, Tianjin University of units on the underground coil heat pump has also carried out many years of research. Guangzhou Institute of the Chinese Academy of Sciences and other units also repeatedly held nationwide for heat pump technology development and application of thematic seminars. We have reason to believe that, while fully learn foreign advanced technology and operations experience, based on strong support at all levels of Government, China's technology sector and the business community work together to rely on its own strength is fully capable of a short time develop with Chinese characteristics of ground source heat pump industry.
