喀什某医院地源热泵系统实测分析

Test and Analysis of Ground-source Heat Pump System on a Hospital in KaShi

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。

The groundwater ground - source heat pump system of a hospital’s outpatient building in Kashi is researched. The system is tested and analyzed for short term in summer and winter respectively. The results show that the standard energy efficiency ratio of the system can be achieved when the system is running under the 29% load in summer, and the first level of energy efficiency can be achieved when the system run at full load operation in winter. Economic analysis shows that the additional initial investment can be recovered with 4. 4 years, which have good economic benefit＇,and also the system solved the blank of the heating by municipal heating network, etc. , which has good social and environmental benefits.
