Abstract

Meeting the DHW (domestic hot water) requirement and the energy used for DHW has an important share in the energy sector today. Air-source heat pumps, one of the systems used to meet this requirement, can also be supported by various renewable energy sources. In such hybrid systems, it is extremely important to model the system and validate this model, since the tests in laboratory conditions are quite difficult. In this study, a system was established for the experimental validation of air source heat pumps used to meet the domestic hot water demand, and the same system was modelled using TRNSYS software to validate the system. The developed model is capable of being supported by renewable energy sources and is a guide for such studies. The heat pump capacity used in the study is a 8 kW, and the experimental tests were carried out for temperatures between 0°C and 15°C. In this study, domestic hot water was continuously heated through a tank and its temperature was increased from 30°C to 45°C. For air source heat pumps, a model with the highest average percentage deviation of 3.5% was developed and validated with experimental data. The developed model is designed to be supported by renewable energy sources, and it is a source study for such hybrid models.

Abstract

Evsel sıcak su ihtiyacının karşılanması ve bunun için kullanılan enerji, günümüzde enerji sektöründe önemli bir paya sahiptir. Bu ihtiyacı karşılamak için kullanılan sistemlerden bir tanesi olan hava destekli ısı pompaları çeşitli yenilenebilir enerji kaynaklarıyla da desteklenebilmektedir. Bu tarz hibrit sistemlerde, laboratuvar şartlarında testler oldukça zor olduğu için sistemlerin modellenmesi ve bu modelin doğrulanmasının yapılması son derece önemlidir. Bu çalışmada, evsel sıcak su ihtiyacını karşılamak amacıyla kullanılan hava kaynaklı ısı pompalarının deneysel doğrulaması için bir sistem kurulmuş ve sistemin doğrulanması için TRNSYS programında aynı sistem modellenmiştir. Geliştirilen model, yenilenebilir enerji kaynaklarıyla desteklenebilecek nitelikte olup, bu tarz çalışmalar için bir rehberdir. Çalışmada kullanılan ısı pompası kapasitesi 8 kW olup, deneysel testler 0°C ila 15°C arasındaki sıcaklıklar için yapılmıştır. Çalışmada evsel sıcak su, bir tank aracılığıyla devamlı surette ısıtılmış ve sıcaklığı 30°C’den 45°C’ye kadar yükseltilmiştir. Hava kaynaklı ısı pompaları için, en yüksek %3,5 ortalama sapma yüzdesiyle bir model geliştirilmiş ve deneysel verilerle doğrulanmıştır. Geliştirilen model, yenilenebilir enerji kaynaklarıyla da desteklenebilecek şekilde tasarlanmış olup, bu tarz hibrit modeller için bir kaynak çalışma niteliğindedir.
