Ground Source Heat Pump Applied Systems Technology Schools and the first series:
Of ground source heat pump system of two techniques
Summary This paper outlines the “ground source heat pump technology and application of line” series of articles in the main content and Europe and the United States between the two main technology routes both competition and interdependence. After the two routes described the development and application in China, existing technical and management problems and System Solutions . Also introduced two governments Ground Source Heat Pump Cooperation Project in a typical case.

KeyWords GHP, Thetechnologyroutes, Issuesandsolutions Introduction We all know, with the Energy And Environment Highlight the problem, ground source heat pump technology over the past decade as a clean, Environmental protection , Energy saving and renewable energy technologies in China have been greatly developed. Even in today’s economic crisis, still maintained its total installed more than 20% a year of rapid development. Heat pump technology to promote the development and marketing, “ground source heat pump system technology and application of line” series will return to the root to the source, ground source heat pump system to elaborate EU system and U.S. Department of the two main technical routes, as well as in indoor systems and outdoor systems Selection of the difference in design; after the introduction of the forward-looking ground-source heat pump technology Building energy efficiency Integrated application, introduced ground source heat pump technology and other energy-saving technologies, including Solar Energy Light and heat, solar, water (ice) storage (heat), cooling towers and hot water preparation with regard to the use; Finally, ground source heat pump technology in all areas of social production and life applications, such as in the tail water use, swimming pool , lawn temperature control, oil field waste heat utilization, industrial applications, large surface water system and so on.
1, ground source heat pump system (GeothermalHeatPumpSystem) defined
Academic is defined by means of a small amount of high energy from a low to high to transfer heat to the air conditioning system. Is defined as a kind of popular through the shallow soil (or groundwater) in heat exchange efficiency energy saving, pollution-free, both heating but also cooling, and provides water for air conditioning systems. Ground source heat pump usually consumes 1kW of energy, the user can get more than 4kW of heat or cold. It does not emit any exhaust to the outside world, waste water, waste residue, is an ideal “green technology.” Because it is a 0-200m of shallow rock and soil to do so called low-temperature heat source heat pump. Energy conversion from the point of view, it is the use of shallow rock and soil and use them as a regenerator of the energy that comes mainly from solar and geothermal energy, so this is an infinite and renewable energy.
Figure 1, ground source heat pump system configuration diagram
Shown in Figure 1, ground source heat pump system is divided into indoor systems and outdoor systems in two parts. Indoor system which distributed and centralized, centralized system in our country often been more familiar, because such systems with traditional central air conditioning system indoor part of the same, plus end of the device by the host composition, this Indoor systems are widely used in China and Europe. Distributed system used in China less, such systems often do not host, heat pump systems and wind systems or water systems combined, and the unit is small, the scattered layout of air conditioning in each district, each district to work alone. This system is widely used in North America since 2000 before being applied to our country.
Outdoor heat exchanger system according to the different ways, using soil heat into the closed ground source heat pump system and the use of groundwater, surface water and artificial regeneration of heat transfer in open water, ground source heat pump system. Closed ground source heat pump system that is commonly referred to as buried ground source heat pump system, open ground source heat pump system known as Water Source Heat Pump System.
