Abstract
For the prevention of global warming, various low GWP refrigerants (R1234yf, R1234ze, R448A, R449A, R452A, R452B, R454B etc.) are proposed as the alternative of R410A and R404A for refrigeration and air conditioning system. PVE lubricants were developed for refrigeration and air-conditioning system with low GWP refrigerants. In this report, the combinations of the low GWP refrigerants and lubricant were evaluated. The evaluation items are physical properties (miscibility, solubility, viscosity, and electric insulation), thermal stability and lubricity.
