U.S. patent application 20160313047 (inventors Avner Sodot and Shaul Hanuna, Israel):
"A beverage cooler includes a heat pump having a cooling element thermally coupled to a negative-heat-energy accumulator. The accumulator (14) includes a heat-energy dispersion arrangement formed from thermally conductive material which is in thermal contact with a quantity of phase-change material having a phase-change temperature above zero Celsius. A conduit for the beverage defines a circuitous path thermally coupled to accumulator. The heat pump draws heat energy predominantly from the phase-change material so as to ensure that a temperature of the phase-change material is reduced by at least as much as the temperature of the beverage within conduit, even under zero-flow conditions. This ensures that the accumulator can he fully charged during periods of low beverage dispensing demand without risk of freezing the beverage within conduit."
U.S. patent application 20160320107 (applicant New West Technologies LLC, Los Angeles, Calif.):
"A thermal energy storage system that enables the discharge of refrigerated air for cooling cargo or passengers in large compartments, such as the trailer of a semi-truck, for a period of time well in excess of several hours. The thermal energy storage system is able to provide refrigeration without operating a conventional VCC unit, the truck engine, or the TRU diesel APU engine during all or a significant portion of the period of the typical range of time that a 53 foot refrigerated the truck is traveling over the road. The thermal energy storage system includes a phase change material reservoir, a cooling system-to-working fluid heat exchanger in fluid communication with the phase change material reservoir, and a phase change material-to-target heat exchanger in fluid communication with the phase change material reservoir. The phase change material reservoir contains a phase change material, a working fluid and a working fluid-to-phase change material heat exchanger."
