Properties of New Low GWP Refrigerants
The purpose of this work is to collect information about alternative low GWP refrigerants, such as HFO-1234yf, R152a, and propane (R290), and investigate the feasibility of using them as replacements for previously used refrigerants. The selected refrigerants have the advantages of providing the same cooling effects, efficiencies, durability, and other performance factors as the original refrigerants do. No modifications are necessarily needed to the existing system. R290 may replace R22 in refrigeration installations with low evaporation temperature if safety measurements are to be considered due to its high flammability. R152a or HFO-1234yf may replace R134a in small, low pressure refrigeration units. HFO-1234yf is favorable due to its milder toxicity and flammability in comparison to R152a…
