以喀什某医院门诊楼地下水地源热泵系统作为研究对象,对该系统夏季和冬季运行工况进行了短期的测试和分析。结果表明:系统夏季在29%负荷下运行时就能达到制冷运行的标准能效比;冬季满负荷运行时能达到系统Ⅰ级能效标准,节能效果明显。经济分析表明,运行4.4年就可回收额外增加的初投资,经济效益良好;系统能很好地解决市政热网的供暖空白期等问题,具有良好的社会和环境效益。
Taking the ground source ground source heat pump system of an outpatient clinic in a hospital in Kashgar as the research object, the system was tested and analyzed briefly in summer and winter. The results show that the system can reach the standard energy efficiency ratio of cooling operation when operating at 29% load in summer and reach the system level Ⅰ energy efficiency standard at full load in winter, and the energy saving effect is obvious. Economic analysis shows that running for 4.4 years can recover the additional initial investment, and the economic benefits are good. The system can well solve the problems such as the heating blank period of the municipal heating network and has good social and environmental benefits.
