地热供暖世界现状及中国清洁供暖的地热选择

摘要

Geothermal space heating is the optimum utility pattern which gives a full play to the medium-low temperature geothermal resources. It already has had 84 years of history in the world. There is 100% geothermal space heating in Reykjavik,the capital of Iceland.It is the world-famous smokeless city.In recent three decades,ground source heat pump (GSHP)has replaced and surpassed the conventional geothermal space heating since it has its advantages of energy saving, emission reduction and simultaneously it is an ideal way both in winter heating and summer cooling.The northern China clean heating is an important measure for implementing energy revolution and governing haze.However,it will be realistic to reduce the use of coal. Comprehensively, geothermal space heating and GSHP have more advantages than the other cleaning energies.%地热供暖是充分发挥中低温地热资源品位优势的最适宜的利用方式,在世界上已有84年历史.冰岛首都雷克雅未克已使用100%地热供暖,是世界闻名的无烟城.近30年来,地源热泵以节能减排和兼可冬季供暖和夏季制冷的优势替代和超越了常规地热供暖方式,得到高速发展.我国北方地区的清洁供暖是实施能源革命和治理雾霾的重要举措,各地的迅速响应决策和实施行动,将能达到切实减煤效果.在可选清洁能源中,地热和地源热泵供暖更具综合优势.
