Carbon Dioxide in Supermarket Refrigeration

Carbon Dioxide in Supermarket Refrigeration


This thesis theoretically and experimentally investigates different aspects of the application of CO2 in supermarket refrigeration. Theoretical analysis has been performed using computer simulation models developed to simulate CO2 indirect, NH3/CO2 cascade, CO2 trans-critical and direct expansion (DX) R404A systems. The models supported the selection of the CO2 system solutions to be tested experimentally and facilitated the design of NH3/CO2 cascade and trans-critical systems test rigs. Performance evaluation and systems’ optimizations have also been carried out.

HY-SAVE® manufactures a range of Co2 Liquid refrigerant pumps for Cascade and re-circulation systems rated at 50 bar, 60 bar and 75 bar design working pressures.
