摘　　要：介绍了一个用柴油机驱动的复合制冷循环，即用柴油机主机带动压缩式循环，同时利用柴油机排气和缸套水的热量作热源驱动吸收式循环。热力学分析和数值计算表明，此复合循环由于实现了不同品位热源的合理利用，减少了不可逆损失，其能效比普通压缩式循环或直燃式吸收循环可分别提高１９％和５８％。By using both work and waste heat of the diesel engine,an integrated absorption compression cycle is proposed and analyzed The performance of this cycle is compared with that of conventional vapor compression refrigeration cycle or direct-fired absorption refrigeration cycle Thermodynamic and numerical investigations are conducted with regard to its feasibility to enhance the efficiency and capacity for cooling applications The results indicate that,due to effective utilization of different grade heat energy and reduction of irreversible loss,a COP improvement of 19%and58%,respectively over conventional compression system with R22 as working fluid and direct-fired lithium bromide absorption system,can be accomplished
