天津市地热资源十分丰富,目前低温地热设备安装容量约112.9兆瓦,为我国各省市之冠。这项资源开发利用得当对减少天津市区低温用热的燃料消耗,改善居民生活条件,减轻城市交通运输负担和防止环境污染具有现实意义。然而,地热开发的初投资很大,采用直接热交换方式供热,地热能利用率低。电动热泵是解决这一问题的有效手 The geothermal resources in Tianjin are very rich. At present, the installed capacity of low-temperature geothermal equipment is about 112.9 megawatts, which is the highest in all provinces and cities in China. The development and utilization of this resource will have practical significance for reducing the fuel consumption of low-temperature heat in Tianjin, improving the living conditions of residents, reducing the burden on urban transportation and preventing environmental pollution. However, the initial investment in geothermal development is very large. It uses direct heat exchange to provide heat and has low geothermal energy utilization. Electric heat pump is an effective solution to this problem
