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 reclaimrnand re-use for hot water services, space heating and cooling systems. This paper investigates thernperformance of an innovative booster R-744 system with heat recovery at different operating conditionsrnbased on its mathematical EES model which includes the variation of the cooling capacities of differentrnsize of stores, discharge pressures, receiver pressure and superheats.
