Analysis Of Economical Efficiency And Behaviors Of Energy Conservation Of District Cooling System

According to the refrigerating unit used by the district cooling system,there aredifferent modes of district cooling systems:separate generation of cooling andpower and combined cooling heating and power.The calculation models of energyconsumption are proposed and as a example of a residential district in Xuzhou,analysis of the economical efficiency of different modes of district cooling systemsis carried on in initial investment and operation cost. In order to reveal thebehaviors of energy conservation of combined cooling heating and power onexergy ,behaviors of energy conservation of typical combined cooling heating andpower system(CCHP) are made by definition of equivalent generating exergyefficiency.Behaviors of energy conservation of combined cooling heating andpower systems are related to specific system mode and object comparedto.Compared with countryside average coal consumption of power supply,energyconservation of combined cooling heating and power system isconditioned.Compared to some heat and power plants which are in shortage of heat load insummer,combined cooling heating and power is energy conservation,it should be developedpositively.
