Disclosed is an apparatus that provides refrigerant based energy storage and cooling. When connected to a condensing unit, the system has the ability to store energy capacity during one time period and provide cooling from the stored energy during a second time period. The system requires minimal energy to operate during either time period, and only a fraction of the energy required to operate the system during the first time period is required to operate the system during the second time period using an optional refrigerant pump.

A refrigeration apparatus of claim 1, wherein said environmental data is derived from a plurality of thermal energy storage units. 15. A refrigeration apparatus of claim 1, wherein at least a portion of said regulation and control operation of said refrigeration apparatus is based upon a time dependent value of energy. 16. A refrigeration apparatus of claim 1, wherein at least a portion of said regulation and control operation of said refrigeration apparatus is based upon at least one of the following: electricity generation price, electricity transmission price or electricity distribution price. 17. A refrigeration apparatus of claim 1, wherein at least a portion of said regulation and control operation of said refrigeration apparatus is in response to a price event, a reliability event, or a load balancing event. 18. A refrigeration apparatus of claim 1, wherein said transmission of said environmental data is performed with a wide area communications interface. 19. A refrigeration apparatus of claim 18, wherein said wide area communications interface is a radio broadcast data system. 20. A refrigeration apparatus of claim 18, wherein said wide area communications interface is a paging system. 21. A refrigeration apparatus of claim 18, wherein said wide area communications interface is an external physical network interface. 22. A refrigeration apparatus of claim 18, wherein said wide area communications interface further comprises an expansion interface, said expansion interface that is used to extend the communication capabilities of said refrigerant management controller and provide means for memory storage and logging.
