Experimental Performance Analysis of a Groundwater Heat Pump System in Erzincan, Turkey

Öz

In this study, a place with a floor area of 80 m² in Erzincan was heated by the Groundwater Heat Pump (GWHP). In this application experimentally investigated, energy and performance analysis of the heat pump and the entire system were performed. Evaporator water flow, condenser water flow and air flows of fan-coil devices was fixed at certain values. Then the measurements have been made under 9 different conditions consisting of these parameters. In the condition which the highest yield is obtained, performance coefficients of the heat pump ( and the system ( were determined 4.27 and 2.92, respectively. In this condition, the average amount of heat discharged from the condenser was calculated to be 14.3 kW. On the other hand, Groundwater quality and temperature that is an important criterion of the GWHP system was found to applicable to Erzincan.

Erzincan İlinde Bir Yeraltı Suyu Kaynaklı Isı Pompası Sisteminin Deneysel Performans Analizi

Öz

Bu çalışmada, Erzincan İlinde bulunan 80 m2 taban alanına sahip bir mekân Yeraltı Suyu Kaynaklı Isı Pompası (YASKIP) ile ısıtılmıştır. Deneysel olarak gerçekleştirilen bu çalışmada ısı pompasının ve tüm sistemin enerji ve performans analizi yapılmıştır. Buharlaştırıcı su debisi, yoğunlaştırıcı su debisi ve Fan-coil hava debisi belirli değerlerde sabitlenmiştir. Daha sonra bu parametrelerden oluşan 9 farklı koşulda ölçümler alınmıştır. En yüksek değerlerin alındığı koşulda, ısı pompasının ve tüm sistemin performans katsayıları sırasıyla 4.27 ve 2.92 bulunmuştur. Bu koşulda yoğuşturucudan atılan ortalama ısı yükü 14.32 kW olarak hesaplanmıştır. Diğer yandan, yeraltı suyu kalitesi ve sıcaklığı önemli bir kriter olan YASKIP sisteminin Erzincan için uygulanabilir olduğu belirlenmiştir.
