武汉地区不同配置的太阳能空调系统性能分析
Performance analysis of different system configurations in solar air conditioning system in Wuhan
摘要：
结合武汉地区具体工程项目，分析了太阳能吸收式空调系统的节能性、经济性及环境效益。当集热器的配置满足60%冷负荷时，全年一次能源利用效率为1.16，与冷水机组+燃气锅炉系统、空气源热泵系统相比节能量明显。由于太阳能集热器价格较高，系统初投资较高，投资回收期较长。优化结果表明，太阳能集热器面积宜满足55%~80%空调负荷的需求，不能低于40%。
Abstract：
Combined with a project in Wuhan, analyses the energy efficiency, economic and environmental benefits of solar absorption air conditioning systems. When the configuration of heat collector meets 60% cooling load, primary energy utilization efficiency of solar air conditioning is 1.16, compared with chillers and gas boiler system/air source heat pump, solar air conditioning gains obvious energy efficiency. Due to the higher price of solar collectors, higher initial investment of solar air conditioning system leads to a longer payback period. Optimized result shows that the area of solar heat collector should meet the demand of 55%-80% cooling load, not less than 40%.
