Abstract: Compositions comprising an activated oil blend in a coordination entity are provided. Also provided are compositions comprising a haloalkane complex can be used as a refrigerant. The compositions can increase the energy efficiency and reduces leakage rates of refrigeration systems. Some compositions comprise at least 0.1 wt % of an oleic oil fatty acid, 0.1 wt % of a linoleic oil fatty acid, and at least 98 wt % of a heat transfer fluid including, for example R-134a. Some compositions comprise an oil blend comprising an oleic acid to linoleic acid ratio of approximately 60:1. At least some of the heat transfer fluid can be complexed with at least one of the organic oil fatty acids.

Abstract: Operation of a refrigeration system can be improved by adding a novel refrigerant composition comprising a mixture of activated long chain fatty acids with a polar heat transfer fluid. Activation is preferably accomplished by blending a mixture of the oils and the heat transfer fluid in a vessel containing a catalyst. Contemplated improvements can include, among other things, a reduction in power consumption, a reduction in evaporator coil condensation, or a reduction in leakage of operating fluid.

Abstract: Compositions including a polar heat transfer fluid that was passed through a vessel containing a catalyst are disclosed. Preferred catalysts can comprise copper, polyamide, stainless steel, or a combination thereof. Compositions can also comprise one or more types of long chain fatty acids, preferably from food oils, and preferably fatty acids that have been activated by virtue of having been passed through a vessel comprising a catalyst.

Abstract: Compositions including an activated oil blend are provided. An oil blend can comprise one or more oils having a long chain fatty acid, preferably an oleic acid or linoleic acid. An oil blend of the inventive subject matter can be activated in an open or closed vessel comprising a catalyst. Some preferred catalysts include copper, a polyamide such as Nylon, and stainless steel. The activated oil blend can be combined with, among other things, a fluid having molecules of sufficient polarity to complex with a fatty acid molecule of the activated oil blend.

Abstract: Refrigeration systems are configured to utilize an operating fluid comprising an activated oil blend. The activated oil blend can comprise one or more precursor oils that are blended in a closed vessel containing a catalyst. Preferred operating fluids also comprise a polar heat transfer fluid such as r-134a, wherein at least some of the polar heat transfer molecules are complexed to a component of the activated oil blend.
