Iğdır Üniversitesi Fen Bilimleri Enstitüsü Dergisi, 2021 In this study, the performance of different refrigerants (with low GWP value) depending on thermophysical properties in the cooling system was evaluated. The cooling capacities of R134a, R445a, R515a, R456a, ND, and R516a refrigerants used in the cooling system are determined per unit refrigerant.
