Abstract
An improved cooling medium for use in a thermal energy storage system is disclosed. The cooling medium comprises water, 1-fluoro-1,1-dichloroethane (HCFC-141b), as the guest molecule and a surfactant selected from the group consisting of DRSC.RTM., EMPHOS PS-21A.RTM., MAPHOS L13.RTM., or MAZEEN C-Z.RTM., POE(2) COCOAMINE. It has been found that any of the above surfactants, and preferably DRSC.RTM. and EMPHOS PS-21A.RTM. encourage clathrate formation at surfactant concentrations far below 300 ppm. Clathrate formation, and the overall efficiency of the thermal energy storage system is increased when the cooling medium of the present invention is used.
