INVESTIGATION OF THE PERFORMANCE OF A CO_2 TRANSCRITICAL CYCLE WITH HEAT RECOVERY FOR RETAIL APPLICATION

摘要

The discharge temperature of CO_2 transcritical system can provide high grade heat that can be reclaim and re-use for hot water services, space heating and cooling systems. This paper investigates the performance of an innovative booster R-744 system with heat recovery at different operating conditions based on its mathematical EES model which includes the variation of the cooling capacities of different size of stores, discharge pressures, receiver pressure and superheats.
