High efficiency refrigerant based energy storage and cooling system

Disclosed is an efficient, energy storage and cooling system that is refrigerant based. 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.
