Abstract
Bu çalışmada solar
termal sistemlerin ısı pompası ile kombinasyonu sayısal olarak incelenmiştir.
Kollektörlerin potansiyel faydası ısı pompası sistemleri kombine sistemlerle
karşılaştırılarak bulunmuştur. Muğla ili için tüm simülasyonlar POLYSUN
programı kullanılarak yapılmıştır. Simülasyonu yapılan sistemler tek haneli
konutların kullanım sıcak suyu ve konut ısıtması ihtiyacını karşılayacak
şekilde tasarlanmıştır. Bu çalışmanın sonuçları sistemin mevsimsel performans
faktörünün hava kaynaklı ısı pompası sistemine eklenen kollektör alanı arttıkça
arttığını göstermektedir. Ancak ısı talebinin karşılandığı sistemlerde ısı
pompasının ısıtma tesir katsayısının azaldığı sonucuna ulaşılmıştır. Bu
sistemde solar enerji sıcak su ihtiyacını karşılamak için kullanılırken bir
taraftan da konut ısıtılmasına destek olmaktadır. Ancak yetersiz kapasitede ısı
pompası seçilerek kollektör sayısının arttırılmasının talebi karşılamadığı bu
nedenle yeterli kapasitede ısı pompası seçilmesi gerektiği saptanmıştır. Isı
talebinin karşılanamadığı sistemlerde ise 2 kollektörden sonra ısıtma tesir
katsayısının sabit kaldığı görülmüştür. 2 kollektörden fazla sayıda kullanılan
kollektörler yazın ihtiyaç fazlalığından kapatılmaktadır. Ancak kış döneminde
ısıtmaya destek olmaktadır.

Abstract
In this study, the
combination of solar thermal systems with heat pump has been investigated
numerically. The potential utility of the collectors is found by comparing heat
pump systems with combined systems. All simulations for the Muğla province were
made using the POLYSUN program. The simulated systems are designed to meet the
demand for hot water and residential heating of single-dwelling houses. The
results of this study show that the seasonal performance factor of the system
increases as the collector field added to the air source heat pump system
increases. However, in the systems where the heat demand is met, the heating
effect coefficient of the heat pump (COPHP) decreases. In this system, solar
energy is used to meet the need for hot water, while also supporting housing
heating. However, it has been determined that the heat pump should be selected
at a sufficient capacity because the increase in the number of collectors by
selecting the heat pump at the insufficient capacity cannot meet the demand.
However, it has been determined that the heat pump should be selected at a
sufficient capacity because the increase in the number of collectors by
selecting the heat pump at the insufficient capacity cannot meet the demand. In
the systems where the heat demand cannot be met, the heating effect coefficient
after 2 collectors is found to be constant. Collectors used in excess of 2
collectors are closed when there is no need for them. However, it supports
heating in winter.
