摘　　要：以合肥、成都和海口地区为例,对当地建筑所用的太阳能光伏空调制冷系统、太阳能吸收式空调制冷系统及传统的蒸气压缩式空调制冷系统进行能耗模拟。用费用年值法对3种制冷的经济性进行分析,同时讨论"全额上网"及"自发自用,余电上网"2种光伏并网模的经济性,并将3种制冷的系统经济性进行比较,讨论当光伏上网标杆电价降到当地脱硫煤上网标杆电价且不计入光伏补贴时光伏制冷的经济性。结果表明:太阳能光伏制冷在2种并网模式下的经济性均优于太阳能吸收式制冷和传统蒸气压缩式制冷;且即使不考虑国家对光伏产业的各项扶植政策,光伏制冷的经济性仍优于太阳能吸收式制冷和传统蒸气压缩式制冷。This paper makes a simulation of energy consumption of the solar PV solar cooling system,the solar absorption air cooling system and the traditional vapor compression air cooling system based on the conditions of Hefei,Cengdu and Haikou. And then,annual cost method is used to conduct economic analysis of three systems. Two kinds of grid-connect modes,"full power to grid"mode and"self-generated,left power to grid"mode,are discussed when considering the economic performance of the PV cooling system. Finally,the economic performance of three systems are compared. This paper also discusses the economic performance of the PV cooling system in the condition that the PV grid purchase price is equal to the local desulphurized coal grid purchase price and the PV subsidies are ignored. The results show that the economic performance of PV cooling under two kinds of grid-connected modes is better than that of solar absorption cooling and traditional vapor compression cooling. Moreover,even if PV subsidy policies are ignored,the economic performance of PV cooling will also be better than that of solar absorption cooling and traditional vapor compression cooling.
