Abstract
A method for operating a refrigeration system includes compressing a refrigerant received from a medium temperature (MT) evaporator unit using a MT compressor unit, and compressing the refrigerant received from a low temperature (LT) evaporator unit using a LT compressor unit. The method includes transferring heat from a portion of the refrigerant provided by the MT compressor unit to a trapped portion of the refrigerant provided by the LT compressor unit using a heat exchanger to produce a pressurized heated refrigerant stream and a cooled refrigerant stream. Pressurizing the refrigerant using isochoric compression (constant volume process) and using waste heat energy increases the overall efficiency of a transcritical CO2 refrigeration system.
