Özet
Bu çalışmada Kastamonu ili şartlarında direk genleşmeli güneş destekli ısı pompasının (D-GDIP) su ısıtma ve mahal ısıtma amaçlı uygulamalarındaki ısıtma performansı incelendi. Evaporatör olarak 10 m2 güneş kollektörü belirlendi. Isı pompasında akışkan olarak R-134a, su ısıtma uygulamasında 500 L hacmindeki su deposu seçildi. Sistemin ısıtma kapasitesi ise 10 kW olarak belirlenerek hesaplamalar yapıldı ve Kasım, Aralık, Ocak, Şubat, Mart, Nisan ve Mayıs aylarındaki performansı incelendi. Yapılan hesaplamalarda sistemin COP değeri en fazla 3.38 ile Mayıs ayında 2.00 ile ise en düşük Aralık ayında olduğu görüldü. Su deposunda ısıtma uygulamasında en fazla sıcaklığa 94.5 °C ile Mayıs ayında ulaşılırken en düşük 44.4 °C ile Aralık ayında ulaşıldı.
In this study, the performans of the direct expansion solar assisted heat pump water heaters (DX-SAHP) were investigated in the Kastamonu region. 10 m2 solar collectors were used in the system as an evaporator. R-134a were used in the vapor compression cycle as a working fluid and 500 L water reservoir were chosen for the energy storage system. Heating capacity of the system were designed 10 kW. System assumed to work in Nowember, December, January, February, March, April, May and the required calculation were made accordingly. The calculated results showed that COP of the system reached up to 3.38 in May and decreased to 2.00 in the December. At the water heater, the maximum temperature of the water was achieved 94.5 °C in May and the lowest temperature was calculated 44.4 °C in December.
