Heat Pump Network HC " Ground Source Heat Pump "The concept first appeared in 1912 in a Swiss patent report, the proposed technology began in Britain and United States. In 1946, the United States, the first source platform Heat Pump System in downtown Portland, Oregon successfully installed. But by the time the impact of the industrial age, this Energy The use patterns not caused widespread attention at the community, whether in technology, in theory, not much development.
The early 70 century, as Oil Of crisis and environmental degradation, caused by the new energy development and use of ground source heat thus Pump Its Energy The characteristics of being concerned. At this time, the Nordic countries, scientists began the practical application of ground source heat pump research and development, and by the State Government's strong support. 1974, Switzerland, the Netherlands and Sweden, the government-funded national demonstration Project Gradually built up, ground source heat pump production technology gradually improved. From the system's technology, the thermal conductivity of the underground system is the most used way of direct use of groundwater, require a certain water temperature, and the technology is relatively rough, or no injection well. The late 70s, scientists began to study the Swedish underground mining open-loop thermal system.
80s of last century is the rapid development of ground source heat pump technology period. During this period, the United States, ground source heat pump manufacturers are active, the establishment of the National Federation of ground source heat pump manufacturers, and gradually perfected the installation of the network. European countries, Switzerland, Sweden and Austria and other countries represented, vigorously promote ground source heat pump heating and cooling technology, the State Government has taken appropriate subsidies and protection policies, making the production and use of ground source heat pump range expanded rapidly.
The late 80s of last century, are reaching ground source heat pump technology has matured, more research scientists working underground system, efforts to improve the efficiency of heat absorption and heat conduction, while more and more attention to environmental impact. Ground source heat pump production increasing year by year, Switzerland and Sweden, the annual increase rate of over 10%. This period the United States, the production and promotion of ground source heat pump fast, had a leap of technological development of the world's production and use of ground source heat pump number one power. 90
since the last century, science and technology workers in Europe and the United States more closely linked together on the ground source heat pump-related environmental issues carried out extensive and in-depth research. 1995 International Academic Conference on geothermal, British scholar Curtis on behalf of international organizations, published a geothermal ground source heat pump system on the application of the survey, which summary to conclude that: 1) ground source heat pump system is the world's energy market, mature technology one of the existing electricity and heating / cooling technology, compared with a stable performance, high reliability, the advantages of less cost, 2) ground source heat pump system with the fuel economy and gas boiler par, 3) if Taking into account include the environmental benefits, energy security and long-term use, including, Ground source heat pump system is the best, highest-tech alternative. According to the 1995 International? 1999 statistics as ground source heat pump product developed momentum is very significant. U.S., Europe, Japan and other countries the use of ground source heat pump as follows:
1) United States: ground source heat pump systems have been installed on more than 20 million units, about 20% annual increase is estimated to 2000, 5-6 million units per year to install ground source heat pump systems, of which 4 million for the ground source heat pump system. United States each year new single family homes (Villa) 1 million, one quarter of the floor taken by the mode of heat, and this is directly supporting ground source heat pump ground heat systems, ground source heat pump system is also a potential market. On the other hand, the U.S. government is very concerned about the development of ground source heat pump technology and marketing conditions, the Energy Department and the university research institutions strongly promote the participation of business and civil scientific and technological resources, can have local source heat pump as the national public plan many years of research. The U.S. Government has funded over a dozen major demonstration projects of ground source heat pump, and in over 20 states to encourage municipal departments and public schools, hospitals and other first install ground source heat pump heating and cooling systems. An optimistic report that the year 2000, the U.S. the number of ground-source heat pump will be installed on 35% annual increase rate.
2) Canada: Ground source heat pump technology later in the day, which closed loop ground source heat pump system in Canada has just started, to 1994, only 7000? 8,000 sets of closed loop ground source heat pump system in use, with open systems geothermal heat pumps does not exceed the million. I am an expert from Components Electronic suppliers, usually analyzes all kind of industries situation, such as self adhesive velcro , sticky back velcro.
