Performance Analysis Of Ground Source Heat Pump

Ground source heat pump systems have been widely applied to both residential and commercial heating and cooling in America and Europe as these systems can make significant contributions to reductions in electrical energy usage and have been recognized as an environmental-friendly alternative to conventional unitary system.However, this technology has seldom been adopted so far in our country. Many a work of research on GSHP and popularizing application need to be done. Vertical U-Tube ground-coupled heat pumps have become increasingly popular because of many outstanding advantage it has, such as: fewer area requirement, fewer limits, running steadily, better performance, lower costs on system maintenance etc. The subjects presented in the first chapter and second chapter focus on the principle, construction, advantages of GSHP system and heat transfer model of vertical U-Tube ground-coupled heat pump.
