Ground-source heat pump systems have been widely applied to both residential and commercial heating and cooling in America and Europe as these new systems can make significant contributions to reductions in electrical energy usage and have been recognized as an environmental-friendly alternative to conventional unitary system.Also,it has seldom been adopted so far in our country .Many a work of research on GSHP and popularizing application need to be done.This article has introduced the superiorities and the place in current technology by its general introduction、forms 、 use、development tendency and the environmental protection.
