| Abstract |
In the last ten years, as a result of economic growth and increasing environmental concerns, the Chinese geothermal engineering has been developed considerably. One typical geothermal heating system is described and a detailed cost analysis. analysis includes drilling, well pump, variable system, water treatment, heat exchangers and terminal user equipment. total cost has been reduced and is suitable for developing countries. Compared to Chinese traditional heating system of burning coal, the low temperature geothermal heating system very competitive. |
