Abstract

Abstract: The distributed-parameters model of heat transfer between the gases and working fluids in the generator was established in the absorption-compression hybrid refrigeration system powered respectively by the exhaust heat and power from engine,as well as the lumped-parameters in the other units.The steady characteristics of the hybrid refrigeration cycle were analyzed at the condition of cooling load being 30 kW.The research results show that the compression refrigeration supplies primarily the cooling load for the bus when the bus drives at idle and low speed; and the absorption refrigeration sub-cycle supplies mainly the cooling load for the bus when it is at middle and high speed.

Key words: exhaust gas, hybrid refrigeration cycle, heat transfer model, steady state characteristics

摘要： 在汽车废热和动力联合驱动的吸收-压缩混合制冷循环中,建立了发动机排气参数和发生器内工作流体传热的分布参数模型和其他换热设备的集中参数模型。分析了混合制冷循环的稳态特性。结果显示,在满足汽车冷负荷为30 kW条件下的混合制冷装置,在汽车怠速或是低速行驶时,主要由压缩子循环满足汽车用冷需求;在中高速时,客车冷负荷主要由吸收子循环来提供。
