Enerji etkin sistemler olarak bilinen hava kaynaklı ısı pompaları (HKIP) bina ısıtmalarında çevre dostu ve ekonomik çözümler olarak karşımıza çıkmaktadır. Ne yazık ki, HKIP'larının çalışma parametreleri ve buna bağlı olarak performansları, dış havanın günlük ve mevsimsel sıcaklık değişimlerinden doğrudan etkilenmektedirler. Bu çalışmada, -10°C ile 18°C dış sıcaklık aralığında, 2°C'lik aralıklarla, logaritmik ortalama sıcaklık farkına dayalı bir hesaplama yöntemi ile 3,4 kW nominal ısıtma gücüne sahip bir HKIP’nın, sabit kompresör gücünde, çalışma parametrelerindeki değişim incelenmiştir. Çalışma, üreticinin yayınlanmış COP verileriyle doğrulanmıştır. Sonuçlar, soğutucu akışkan buharlaşma ve yoğuşma sıcaklığının ve basıncının, COP’un ve yoğuşturucu ısıtma yükünün dış hava sıcaklığına göre değişimini veren grafiklerle paylaşılmıştır. Dış hava sıcaklığının -10°C'den 18°C'ye yükselmesi, COP değerini 3,38'ten 5,49'e yükseltmektedir. Ortam sıcaklığına paralel olarak gerçekleşen buharlaşma basıncındaki artışın tespiti, sistemin soğutucu akışkan dolum seviyesinin manometre ile kolayca kontrolüne imkan verebilir. Bu çalışma, bir HKIP'nın dış ortam sıcaklığına bağlı çalışma parametrelerini belirlemeyi amaçlayan araştırmacılar ve saha çalışmalarında bu bilgilere ihtiyaç duyan teknik personeller için faydalı bir rehber olabilir.

Air source heat pumps (ASHP), known as energy efficient systems, emerge as environmentally friendly and economical solutions for building heating. Unfortunately, the operating parameters of ASHPs and accordingly their performance are directly affected by the daily and seasonal temperature changes of the outside air. In this study, change in operation parameters of a selected ASHP with 3.4kW nominal heating capacity is investigated with a calculation method based on the logarithmic mean temperature difference, between -10°C to 18°C outdoor temperature range with 2°C steps, at constant compressor power. The study is verified with published COP data of the manufacturer. Results are shared with graphs that give the variation of refrigerant evaporation and condensation temperature and pressure, COP, and condenser heating load according to outdoor air temperature. A raise from -10°C to 18°C in outdoor temperature, increases the COP value from 3.38 to 5.49. Detection of the increase in evaporation pressure in parallel with the outdoor temperature may allow easy control of the refrigerant charge level with a manometer. This study can be a useful guide for researchers who aim to determine the outdoor temperature dependent operating parameters of an ASHP and for technical personnel who need this information in fields.
