IIR documentSummary
With the focus on supermarket applications, this paper provides an overview of various system solutions with CO2 as refrigerant, such as cascade-, booster- and parallel-compression systems, and discusses their advantages and disadvantages, along with a comparison of system COPs. The application of CO2 requires appropriate measures with respect to the system design, control, etc. to ensure reliable and efficient operation. These measures are discussed from the application engineering point of view, with the emphasis on the challenging issues regarding capacity regulation, operating temperatures and oil distribution of CO2 systems. See also the Bulletin of the IIR, reference 2009-0639.
