【摘要】 对太阳能为热源的增强型喷射式制冷系统进行了热力学分析，并进行了初步实验。在９０℃热源、１２℃蒸发温度和２０００Ｗ制冷量的额定工况下，喷射系数可达０．６５１，整个系统的ＣＯＰ值达０．３３４，比传统的纯喷射制冷循环的ＣＯＰ值（０．２３）提高５０％。更多还原

【Abstract】 n solar thermal conversion.solar cooling is one of the promising application due to the climatic coincidence of energy supply of demand.In this paper.the thermodynamic analysis and some preliminary experiments of solar enhanced ejector cooling cycle are given.The experimental results show that under the specified test condition of 90℃ heat source(from solar hot water).12℃ evaporation temperature and 2000W cooling capacity. the ejector mass flow entrainment reaches 0.651.system COP =0.334 which is 50% higher than that of the conventional ejector cycles.更多还原
