Abstract
Compositions, systems and methods for introducing lubricants, and additives, that are designed to work with environmentally friendly refrigerants into vehicle heat management systems including passenger compartment air conditioning (A/C) systems are disclosed. Methods for charging lubricants and specific additives using environmentally desirable (low GWP) refrigerant or refrigerant blend compositions into an environmentally friendly system, such as a system that uses HFO-1234yf, are also disclosed.
Claims15
A composition comprising about 50 to about 80 wt % polyol ester lubricant and about 20 to about 50 wt % consisting essentially of 1234yf refrigerant, 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 945kPa within a sealed container when measured using ASHRAE 97:
- 2007 and wherein the lubricant comprises less than 50 ppm water when measured in accordance with ASTM E284.
