Abstract
A method of operating a refrigeration system is disclosed. The method comprises cooling a refrigerant using a first high side heat exchanger and reducing a pressure of a first portion of the refrigerant received from the first high side heat exchanger using a first expansion valve. The method comprises separating the refrigerant received from the first expansion valve into a liquid refrigerant and a vapor refrigerant using a receiver tank. The method comprises cooling a first space with the liquid refrigerant received from the receiver tank using a first low side heat exchanger, and recycling the refrigerant exiting the first low side heat exchanger to the receiver tank.
