Additional information

This paper is Part II following Part I published in the same Journal. In this part, the developed software ‘SuperSim’ was used to evaluate and compare the performance of a CO2 booster refrigeration system with that of a conventional R404A multiplex system in a supermarket application. Floating head pressure control was implemented for both systems when they are in subcritical cycles. For the CO2 system, the supercritical head pressure was optimized as a function of ambient air temperature. As a result, the system performance will benefit from a lower ambient temperature and a sizeable heat recovery for the CO2 system.
