    Abstract

    This study investigates evaporation heat transfer characteristics of several refrigerants with low global warming potential (GWP) in different types of plate heat exchangers. Brazed plate heat exchanger and shell and plate heat exchanger, which are widely used in a refrigeration system, are used as test sections. Hydrofluoroolefin (HFO) refrigerants with low GWP such as R1234yf, R1234ze(E), and R1233zd(E) are used as working fluids. The evaporation heat transfer coefficient and pressure drop of the low GWP refrigerants in the plate heat exchangers are measured and analyzed by varying the saturation temperature, mass flux, vapor quality, and heat flux. Based on the performance comparison between the plate heat exchangers, the brazed plate heat exchanger shows higher heat transfer coefficient, whereas the shell and plate heat exchanger exhibits an advantage in the low pressure drop.
