基于适宜性的西安市水源热泵开发潜力评估

依据适宜性评价,综合考虑水质、回灌率、已运行情况以及环境条件对水源热泵开发的影响,对西安市水源热泵开发利用潜力进行评估。结果表明:西安市适宜性面积占研究区总面积31.52%;将西安市水源热泵开发潜力划分为5类潜力类型区:Ⅰ、Ⅱ类潜力区主要分布于西安市北部,以平原为主,为开发潜力优、良区;Ⅲ类潜力区主要分布于临潼中部、阎良东部、长安南部、户县和周至南部等地,为适度开发潜力区;Ⅳ类潜力区主要分布于蓝田西南、临潼南部以及长安丘陵区,为不宜开发潜力区;Ⅴ类地区为秦岭山地和禁采区,应限制水源热泵的开发利用。研究可确定西安市不同地域的水源热泵开发利用潜力,研究结果可为编制西安市水源热泵开发规划提供参考。

Evaluation the potential of groundwater heat pumps exploitation based on its suitability in Xi'an City

According to the suitability evaluation, and further considering the influence of water quality, recharge rate, operation and environmental conditions, the paper evaluates the exploitation potential of Xi''an groundwater heat pump (GWHP). The results show that 31.52% of Xi''an area is suitable, and the development potential of the GWHP is divided into five types. Type I and II mainly are distributed in plain region in the north of Xi''an City as priority areas. Type III is widely distributed in central Lintong, Eastern Yanliang, southern Chang''an, Huxian and southern Zhouzhi as moderate development areas. Type IV is mainly in the hilly area of southwest of Lantian, Southern Lintong and Chang''an, which is unsuitable to develop. Type V is the area of Qinling Mountains and the ban area where should limited GWHP. This study can be used to determine the potential of the development and utilization of GWHP in different regions of Xi''an. The results can be used as reference for the development of GWHP in Xi''an.
