The invention discloses an energy-saving type heavy truck refrigerating system, and belongs to the technical field of automobile environment control systems. The system completes two functions of energy conservation and refrigeration. The system performs waste heat recovery on engine tail gas, so that a power turbine does work to drive a generator to generate electricity, one part of electricity drives a working medium pump to work, the other part of electricity is input into a motor, and the requirement of the motor for a vehicle-mounted power supply is reduced. Meanwhile, two-stage pressurization is adopted for system air supply, a cooling turbine drives a second-stage air compressor, the pressurization ratio of a first-stage air compressor can be reduced, the output work of the coolingturbine is fully utilized, and extra power supply is not needed. Through system thermodynamic calculation, the feasibility of the energy-saving type heavy truck refrigeration system is further explained.

    本发明公开了一种节能型重型卡车制冷系统,属汽车环境控制系统技术领域。系统完成了节能与制冷两个功能。系统通过对发动机尾气进行余热回收,使动力涡轮做功带动发电机发电,一部分电带动工质泵工作,另一部分电输入电动机,减少电动机对车载电源的需求。同时系统供气采用两级增压,冷却涡轮驱动二级压气机,可降低一级压气机的增压比,且充分利用了冷却涡轮的输出功,无需额外供电。并且通过系统热力计算,进一步说明了该一种节能型重型卡车制冷系统的可行性。
