Flame suppression and lubricant interaction of hydrocarbon mixtures for household refrigerator-freezers.

Author(s) : BASKIN E., SMITH N. D., PERRY R., TUFTS M.

Summary

Hydrocarbons are stratospheric ozone friendly and have good heat transfer properties. Experimental studies have revealed that specific mixtures of hydrocarbons are more energy efficient than R12. Also, hydrocarbons are compatible with the current lubricant (mineral oil) used in household refrigerator-freezers. One drawback to the use of hydrocarbons is their flammability, but trifluoroiodomethane (CF3I) has been shown to suppress the flammability of hydrocarbons and other flammable refrigerant candidates. The work focused on blending the minimum amount of CF3I with previously optimized refrigerator-freezer-tested hydrocarbon mixtures to reduce their flammability. Optimized hydrocarbon mixtures were shown to be 3% more energy efficient than R12 operating in a conventional household refrigerator-freezer. The hydrocarbon mixtures along with the selected quantity of the CF3I were retested in the same refrigerator-freezer in which the hydrocarbon mixtures were previously optimized. Results are given.
