Abstract (en)

A refrigeration system 20 includes a compressor 22, a heat rejecting heat exchanger 24, an expansion device 28, and a heat absorbing heat exchanger 30 fluidly connected to form a closed loop through which a refrigerant is configured to circulate. An economizer heat exchanger 30 is located downstream from an outlet of the heat rejecting heat exchanger 24 and upstream from the expansion device 28 relative to a flow of the refrigerant. The economizer heat exchanger 30 has a main flow path 36 and an economizer flow path 38 formed therein. All liquid refrigerant provided at an outlet of the heat rejecting heat exchanger 24 is provided to the main flow path 36.
