提出了一种新型串级连接,即将有机朗肯循环(ORC)与氯化钙/氯化钡两级吸附式制冷机组串联起来.ORC系统工质选为R245fa,假设等熵效率与功电转化效率乘积为0.4,当膨胀机进口压力从0.6 MPa变化到1.1 MPa,能量效率、(火用)效率、发电量变化范围分别是3.9％～5.5％、34％～31.5％、392～600 W,如果增加回热器后,能量效率从4.2％变化到6.0％;利用压缩空气模拟工质R245fa推动膨胀机,当进口压力为1 MPa时,膨胀机的等熵效率与功电转化效率乘积是0.53,发电量为300 W;两级吸附式制冷系统,当热源温度从75℃变化到95℃,制冷量、能量效率及(火用)效率变化范围分别是1.42～2.2 kW、13.4％～16.8％、18.1％～16.6％;有机朗肯循环与两级吸附制冷串连起来,热源温度为98℃时,系统总的能量效率为11.8％,(火用)效率为23.7％,发电量为560 W,制冷量是2.2kW.
