This paper the advantagee, the currently used ecale ae well ae the level for geothermal heating under the circumetancee in China. The utilization of low temperature geothermal climate conditione in Chinese cities, and the main factore of impact on useable temperature drop and their values for reference are analyeed. Taking the duelling area., North , of Tianjin Atheletic an between two heat supply projecte of low temperature geothermal and coal- burning boiler for their initial investment and annual production coet made. Finally, the paper the geothermal gradient extent i n which exploit low temperature geothermal in Chinese cities. |
