Compositions, system and methods for introducing POE lubricant into an electric (HEV, PHEV, EV) automotive air-conditioning/heating system or stationary air-conditioning/heating system or stationary refrigeration system using lower or low GWP refrigerant or refrigerant blends

A composition comprising about 50 to about 80 wt % polyol ester lubricant and about 20 to about 50 wt % of a fluoroolefin refrigerant comprising 1234yf, wherein the refrigerant exhibits a global warming potential (GWP) of less than about 150 wherein the lubricant is miscible with the refrigerant at over a temperature range of −18° C. to 37° C. at a pressure of 160 kPa to 945 kPa within a sealed container when measured using ASHRAE 97:

• 2007, wherein the lubricant comprises less than 50 ppm water when measured in accordance with ASTM E284, and wherein the composition has a total acid number less than one of 3.3 mg KOH/g, 1.5 mg KOH/g and 1.0 mg KOH/g as measured per ASTM D664-01 at 175° C.
