Impact of oil presence on the evaporator enthalpy working with R1234ze(E) and R1234yf

R1234ze(E) and R1234yf, as green refrigerants, have received more and more attention in recent years. To better understand the performance of the evaporator working with a refrigerant/lubricating oil mixture, the solubilities of R1234ze(E)/POE85 and R1234yf/POE85 were measured using the isochoric saturation method in the temperature range from 278.15 K to 348.15 K. The NRTL model was used to correlate the new data. Using the new data, the...
