Abstract

TURKEY Summary In the present study, exergy analysis of a ground source heat pump (GSHP) is performed. For this purpose, a horizontal type GSHP test system is installed at Sivas Cumhuriyet University in Sivas Province. GSHP system consists of three main circuits. These are the ground heat exchanger (GHE), the heat pump (HP) and the heating circuit. The temperatures and pressures are measured at the various points of the system. Besides, the mass flow rate of the working fluid circulating in the GHE, heat pump and heat circuit are measured. In addition, power consumption of the compressor and the pumps are measured. Measured data were recorded every minute. The test data used in the calculations are related to the coldest day, December 18, 2016. Exergy loss, exergy efficiency, exergy loss ratio and thermodynamic perfect degree for each element of the system are computed. Exergy efficiency and thermodynamic perfect degree of the system are calculated as 0.27 and 0.86

土耳其锡瓦斯寒冷气候条件下地源热泵系统的火用分析

在本研究中，对地源热泵(GSHP)进行了火用分析。为此目的，在锡瓦斯省的锡瓦斯大学安装了一个卧式地源热泵测试系统。地源热泵系统由三个主要电路组成。这些是地面热交换器(GHE)，热泵(HP)和加热电路。在系统的各个点测量温度和压力。此外，还测量了GHE、热泵和热回路中循环的工质流量。此外，还测量了压缩机和泵的功耗。每分钟记录一次测量数据。计算中使用的测试数据与2016年12月18日最冷的一天有关。计算了系统各要素的火用损失、火用效率、火用损失比和热力完美度。系统的火用效率和热力完美度分别为0.27和0.86
