太阳能-垂直埋管地源热泵供热能耗研究(中文5600字,英文4500字,英文PDF)
摘要:热泵系统是理想的替代现有的油、气取暖系统的方式。通过使用来自环境的免费冷热源并且可以同时减少化学能源的消耗,热泵系统的花费比较少。为了测试埃尔祖鲁姆省寒冷气候下太阳能地源热泵的效果,本文做了一项实验。试验装置包括太阳能集热器,地埋管换热器,水-水热泵,循环水泵和其他测量设备。在这项实验研究中将测试系统的性能。本次实验从2008年10月到2009年5月进行。获得的实验结果用于计算热泵性能系数(COP)和系统性能系数(COP)。热泵的性能系数在3.0-3.4,系统性能系数在2.7-3.0。这项研究还表明,该系统可用于在土耳其埃尔祖鲁姆的寒冷气候地区的住宅供暖。

Energy analysis of a solar-ground source heat pump system with vertical closed-loop for heating applications
Abstract:A heat pump system is the ideal way to extend the heat supply of existing oil or gas fired heating system. Consumption costs are lowered through the use of free energy from the environment, and the dependence on fossils fuels simultaneously reduces. In order to investigate the performance of the solar-ground source heat pump system in the province of Erzurum having cold climate, an experimental set-up was constructed. The experimental apparatus consisted of solar collectors, a ground heat exchanger(GHE),a liquid-to-liquid vapor compression heat pump, water circulating pumps and other measurement equipments. In this study, the performance of the system was experimentally investigated. The experimental results were obtained from October to May of 2008-2009. The experimentally obtained results are used to calculate the heat pump coefficient of performance (COP) and the system performance (COPS). The coefficient of performance of the heat pump and system were found to be in the range of 3.0-3.4 and 2.7-3.0, respectively. This study also shows that this system could be used for residential heating in the province of Erzurum being a cold climate region of Turkey.
