Patent ID: 8505313

Claim:
A thermal energy storage and cooling system comprising: a refrigerant loop comprising: a condensing unit, said condensing unit comprising a compressor and a condenser; an expansion device connected downstream of said condensing unit; and, an evaporator on a primary side of an isolating heat exchanger located downstream of said expansion device; a cooling loop on a secondary side of said isolating heat exchanger in thermal communication with said primary side of said isolating heat exchanger comprising: a tank filled with a fluid capable of a phase change between liquid and solid and containing a primary heat exchanger therein, said primary heat exchanger in thermal communication with said secondary side of said isolating heat exchanger, said cooling loop that allows transfer of cooling from said secondary side of said isolating heat exchanger to said primary heat exchanger to cool said fluid and to freeze at least a portion of said fluid within said tank in a first time period, said cooling loop that allows transfer of cooling from said primary heat exchanger to said secondary side of said isolating heat exchanger to cool said primary side of said isolating heat exchanger in a second time period; and, a load heat exchanger in thermal communication with said isolating heat exchanger and said condensing unit that allows cooling capacity to be transferred from said condensing unit to said load heat exchanger or said primary heat exchanger to said load heat exchanger.
