Abstract
A refrigeration circuit with thermal storage is disclosed. The circuit refrigeration comprises a gas-cooler comprising an inlet, and an outlet, and a compressor unit comprising one or more compressors. The outlet of the compressor unit is fluidically connected to the inlet of the gas-cooler. The refrigeration circuit comprises evaporators comprising an inlet, and an outlet, where the outlet of the evaporators is fluidically coupled to the inlet of the compressor unit. The refrigeration circuit comprises a flash tank fluidically connected between the gas-cooler and the compressor unit, and the evaporators and the compressor unit. Further, the circuit refrigeration comprises a thermal battery fluidically coupled to the gas-cooler, the flash tank, the compressor unit, and the evaporators. The thermal battery is used as a heat source and a heat sink based on the energy pricing of an electric grid to optimize the operation of the gas-cooler, evaporators, and the compressors.
