The effect of the outdoor parameters affecting the performance of the air source heat pump, which is one of the most important alternatives to achieve the zero emission target and reduce external dependence on energy, on the condenser condensation temperature and evaporator evaporation temperature was investigated by moderated mediation analysis in cooling mode. Furthermore, as a result of the optimization study, mathematical equations based on external environmental parameters were extracted. With the optimization model used in this study, the effect of outdoor temperature, wind direction, and relative humidity on condenser condensation temperature was found to be 39,82%, 24,72%, and 7,65%, respectively. The outdoor temperature has a negative indirect effect on the evaporator evaporation temperature by 1,32%. It was discovered that relative humidity has a 0,63% effect on the interaction between outdoor temperature, wind direction, and evaporator temperature.

Öz

Sıfır emisyon hedefini yakalamak ve enerjide dışa bağımlılığı azaltmak için en önemli alternatiflerden biri olan hava kaynaklı ısı pompasının performansını etkileyen dış ortam parametrelerinin kondenser yoğuşma sıcaklığı ve evaporatör buharlaşma sıcaklığı üzerindeki etkisi soğutma modunda moderated mediation analizi ile araştırılmıştır. Bu çalışmada, soğutma modunda çalışan hava kaynaklı ısı pompası için moderated mediation optimizasyon modeli kullanılarak dış ortam parametrelerine bağlı matematiksel eşitlikler elde edilmiştir. Kullanılan optimizasyon modeliyle kondenser yoğuşma sıcaklığı üzerinde dış ortam sıcaklığının %39,82, rüzgar yönünün %24,72 ve bağıl nemin %7,65 oranında etkisi olduğu bulunmuştur. Dış ortam sıcaklığı, evaporatör buharlaşma sıcaklığı üzerinde %1,32 oranında olumsuz bir dolaylı etki oluşturmaktadır. Dış ortam sıcaklığı, rüzgar yönü ve evaporatör buharlaşma sıcaklığı arasındaki etkileşim üzerinde bağıl nemin %0,63 oranında etkisi olduğu elde edilmiştir
