地源热泵系统（包括土壤源、地下水源、地表水源、污水源）
Ground sourcing Heating Pump (include soil, underground water, ground water and sewage water)

    地源热泵是一种利用地下浅层地热资源（也称地能）的既可供热又可制冷的高效节能系统，主要有：土壤源热泵技术、地下浅层水源热泵技术、地表淡水源热泵技术、污水源热泵技术及海水源热泵技术。地源热泵通过输入少量高品位能源（电能），实现低温位热能向高温位热能转移。地能分别在冬季作为热泵供暖的热源和夏季制冷的冷源。

     GSHP is a high efficient energy saving system for heating and cooling which use the  underground soil energy, that include: soil heating pump, underground water heating pump, ground water heating pump, sewage heating pump and sea water heating pump. Giving little power energy can transfer the low level energy to high level energy. Soil energy can heat the circulation water in winter through geting the heat in soil and cool in summer through removing the heat in the soil.
