Abstract：
Ground source is a kind of regenerative energy. Based on the principle of ground source heat pump technique, applicability of such technique in Hangzhou region is discussed on the aspects of environment, technical type, project category, economic efficiency and operating effect, etc. It is concluded that annual total heat emission of larger buildings, such as office building, is far higher than annual total heat absorption. Composite ground source heat pump techniques may be adopted and soil ground source heat pump technique has favorable application in smaller villa building.
