以太阳能驱动的有机朗肯-蒸汽压缩空调为研究对象,通过热力学模拟手段对工质类型、系统设计以及影响因素进行研究。结果表明:工质发生温度和冷凝温度对系统性能有重要影响,单位面积集热器的制冷功率和系统总效率随工质发生温度先增后减,随冷凝温度的增加而降低。通过性能对比发现,R123工质是较适宜的工质。在工质发生温度、冷凝温度和蒸发温度分别为120、45和5℃时,太阳能空调对应的单位面积集热器的制冷功率和系统总效率分别为136.01 W/m2和44.12%,论证了太阳能驱动的有机朗肯-蒸汽压缩空调系统的可行性。
Taking solar powered organic Rankine - VAC as research object, the type of refrigerant, system design and influential factors were studied by means of thermodynamic simulation. The results show that the working temperature and the condensing temperature have an important influence on the system performance. The cooling power per unit area and the total system efficiency increase first and then decrease with the temperature of the working fluid and decrease with the increase of the condensing temperature. Through the performance comparison found that R123 working fluid is more suitable working fluid. The cooling power and total system efficiency of unit area collector corresponding to solar air conditioner are respectively 136.01 W / m2 and 44.12% when working medium temperature, condensing temperature and evaporating temperature are 120, 45 and 5 ℃, respectively. It is proved that solar energy Driven Organic Rankine - Vapor Compression and Air Conditioning System Feasibility.
