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％。
The thermodynamic analysis of enhanced jet refrigeration system with solar energy as heat source was carried out and a preliminary experiment was carried out. Under the condition of 90 ℃ heat source, 12 ℃ evaporation temperature and 2000W cooling capacity, the injection coefficient can reach 0.651 and the whole system COP value reaches 0.334, which is lower than the COP value of the traditional pure jet refrigeration cycle. 23) increased by 50%.
