Bu çalışmada çift borulu ısı değiştirici, gövde borulu ısı değiştirici ve plakalı ısı değiştirici için termodinamik analiz yapılmıştır. Bu 3 tip ısı değiştiricinin performansları deneysel olarak test edilmiştir. Isı değiştirici test bölgesinin soğuk su debisi 1.5 L/dk değerinde sabit tutulurken sıcak su debisi 0.8 L/dk, 1.6 L/dk ve 2.4 L/dk değerlerinde değiştirilmiştir. Sıcak su beslemesi 50°C, 60°C ve 70°C olarak seçilmiştir. Deneyler hem karşıt akışlı hem de paralel akışlı olarak yapılmıştır. Yapılan deneyler neticesinde sıcaklığın ve debinin artışı ile ısı değiştiriciden alınan gücün arttığı tespit edilmiştir. Birim alandan elde edilen ısı transferi miktarı değerinin en yüksek olduğu ısı değiştirici tipi gövde borulu ısı değiştirici iken en düşük performansı çift borulu ısı değiştirici tipi göstermiştir.

In this study, thermodynamic analysis was performed for tubular heat exchanger, shell and tube heat exchanger, and plate heat exchanger. The performances of these 3 types of heat exchangers were experimentally tested. The cold water flow rate of the heat exchanger test zone was kept constant at 1.5 L / min, while the hot water flow rate was set at 0.8 L / min, 1.6 L / min and 2.4 L / min. The hot water tank temperature was selected as 50 ° C, 60 ° C and 70 ° C. The experiments were conducted in both counter flow and parallel flow. As a result of the experiments, it was observed that increasing temperature and flow rate increased the power taken from the heat exchanger. The heat exchanger type with the highest amount of heat transfer from the test zone is the shell and tube heat exchanger, and the tubular heat exchanger type has the lowest performance.
