Abstract: Disclosed is a method and device to efficiently regulate flow of refrigerant while maintaining a sealed chamber in systems providing stored thermal energy for use during peak electrical demand. A mixed-phase regulator replaces the thermostatic expansion valve used in conventional air-conditioning systems that, along with capillary tubes and orifices, regulates the refrigerant fed from the compressor to the heat load.

Abstract: Disclosed is an efficient refrigeration 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.
