中文摘要:

为研究兰州盆地中深层地热水供暖系统供热性能和节能效益，依托兰州市七里河区彭家坪首个地热供暖示范工程设计开展了一个供暖季的地热供暖试验，并对该系统在整个供暖季的运行数据进行了分析。结果表明，该系统可以使供热用户端的室内温度维持在20 ℃以上，供暖效果良好，且系统运行一个供暖季，可以使CO₂的排放量减少2 300. 61 t，SO₂的排放量减少18. 63 t，减少粉尘排放量9. 31 t，同时其单位面积运行费用为14. 25元／m²，运行成本明显低于燃气锅炉，低碳减排效果较好，经济效益显著。热泵为该系统主要的耗电设备，其运行费用占系统总运行费用的５３．５６％，建议在地热供暖系统的设计中，重点优化热泵机组的选型，这对提升系统经济效益具有非常重要的意义。

英文摘要:

In order to study the heating performance and energy-saving benefits of the middle and deep geothermal water heating system in Lanzhou Basin, this paper relies on the design of the first geothermal heating demonstration project in Pengjiaping, Qilihe District, Lanzhou City, to carry out the geothermal heating test for one heating season, and analyses the operation data of the system in the whole heating season. The results show that the system can keep the indoor temperature of the heating user end above 20 ℃, with good heating effect, and the system can reduce CO₂ emission by 2 300. 61 t, SO₂ emission by 18. 63 t, and dust emission by 9. 31 t in one heating season, and at the same time, the operating cost per unit area is 14. 25 yuan／m², the operating cost is significantly lower than that of the gas boiler system, and the low-carbon emission reduction effect is good, and the economic benefits are significant. The heat pump is the main power-consuming equipment of the system, and its running cost accounts for half of the total running cost of the system. It is suggested that in the design of the geothermal heating system, the focus should be on optimising the selection of the heat pump unit, which is of great significance in enhancing the economic efficiency of the system.
