IIR documentSummary
For light commercial systems, a solution with CO2 is to use the transcritical cycle. It is well known that active control of the system high pressure must be applied for transcritical CO2 cycles to obtain good cycle efficiencies. This paper describes the implementation and performance measurements of light commercial refrigeration applications. The authors compare the results to baseline R134a systems and relate the results to steady state analysis. With a change from capillary tube R134a systems to a CO2 system with a control valve, the authors found energy reductions up to 37% depending on application and conditions.
