The environmental impact of conventional HFC refrigerants and their subsequent phasing out has led to the evaluation of heat transfer and pressure drop performance of alternative low-GWP refrigerants. This seminar highlights the flow condensation performance of several low-GWP refrigerants, both pure and HFC/HFO mixtures, in 0.95 mm multi-channels tube, and smooth and internally enhanced microfin tubes of 4 mm to 9 mm diameter. R-32, R-1234yf, R-454C, R-450A, and R-513A were experimentally investigated to compare with R134a and R410A, and with existing correlations. This session benefits engineers with refrigerant selection and design of air-to-refrigerant and liquid-to-refrigerant heat transfer equipment.
