Peak load shifting via thermal energy storage using a thermosyphon

Abstract

Systems and methods for thermal energy storage are disclosed. A thermal energy storage unit and an evaporator coil may form a thermosyphon. In an energy consumption mode, refrigerant may be directed from a compressor, through a condenser coil, to an evaporator coil via a first 3-way valve, and back to the compressor via a second 3-way valve. In an energy storage mode, refrigerant may be directed from the compressor, through the condenser coil, to a thermal energy storage unit via the first 3-way valve, and back to the compressor via the second 3-way valve. In an energy discharge mode, refrigerant may be directed from the thermal energy storage unit to the evaporator coil via the second 3-way valve, and back to the thermal energy storage unit via a vapor line.
