Bu çalışmada Van iklim koşullarında yer alan farklı ayar noktası sıcaklıklarına sahip iki seranın ısıtma ihtiyacının karşılanması için güneş enerjisi destekli bir su kaynaklı ısı pompası sistemi TRNSYS programı aracılığıyla modellenmiştir. Bu seralar ayar noktası sıcaklıklarına göre soğuk ve ılık sera olarak adlandırılmış olup, ayar noktası sıcaklıkları soğuk ve ılık sera için sırasıyla 6 °C ve 17 °C değerlerindedir. İki sera sistemi içinde tek katlı cam ve çift katlı polietilen (ÇPE) sera örtüsü malzemeleri kullanılmış ve yıllık ısıtma enerjisi gereksinimleri karşılaştırılmıştır. Her iki seranın ısı yükleri TRNSYS programı yardımıyla hesaplanmış ve buna göre yeterli kapasitede ısı pompası seçimi yapılmıştır. Soğuk sera sisteminde kullanılan ısı pompasının nominal ısıtma kapasitesi ve ısı pompası güç tüketim değerleri sırasıyla 30000 kJ/h ve 6000 kJ/h iken ılık sera sistemine ait ısı pompasının nominal ısıtma kapasitesi ve ısı pompası güç tüketimi sırasıyla 64252 kJ/h ve 17848 kJ/h’dır. Bu çalışmada elde edilen sonuçlara göre, soğuk ve ılık serada cam sera örtüsü yerine çift katlı polietilen (ÇPE) sera örtüsü kullanımı sonucunda soğuk ve ılık serada sırasıyla yıllık % 55 ve % 44 ısıtma enerjisi tasarrufu sağlanmaktadır.
In this study, two greenhouses with different adjustment temperatures included in the Van climate conditions have been modeled through the TRNSYS program, a water-based thermal pump system supported by solar energy to meet the heating need. These greenhouses are referred to as cold and warm greenhouses according to the adjustment point temperature, and the adjustment point temperature for cold and warm greenhouses is at 6 °C and 17 °C respectively. In two greenhouse systems, single-storey glass and double-storey polyethylene (CPE) greenhouse cover materials were used and annual heating energy requirements were compared. The heat loads of both greenhouses were calculated with the help of the TRNSYS program and accordingly the heat pump was selected with sufficient capacity. The nominal heating capacity of the heat pump used in the cold heating system and the heat pump power consumption values are 30,000 kJ/h and 6000 kJ/h respectively, while the nominal heating capacity of the heat pump of the hot heating system and the heat pump power consumption are 64252 kJ/h and 17848 kJ/h respectively. According to the results obtained in this study, the use of double-layer polyethylene (CPE) greenhouse cover instead of glass greenhouse in cold and warm greenhouse provides 55% and 44% annual heating energy savings, respectively, in cold and warm greenhouse.
