The invention belongs to the technical field of waste heat recovery and heat pumps, and particularly relates to an organic Rankine cycle and heat pump cycle coupling device for a diesel-electric hybrid vehicle, which is functionally divided into an intake and exhaust passage, an organic Rankine cycle tail gas waste heat recovery system, a heat pump cycle system, a cooling liquid cycle system and a control system. Compared with the prior art, the exhaust emission temperature of the vehicle can be reduced, emission of harmful gas is reduced, and the purpose of protecting the environment is achieved; tail gas emission waste heat is effectively recycled, recycling of low-grade heat energy is achieved, consumption of fuel oil is reduced, combined cooling heating and power is achieved, and therefore the energy utilization rate is increased; a cold and heat source of the heat pump system is changed into cooling liquid from air, so that the wide-temperature-range use range of the heat pump system in a vehicle-mounted environment can be widened; the coupling system shares the heat exchanger, the size and weight of the coupling device can be reduced to a certain extent, and the compactness of the system is improved.
本发明属于余热回收技术和热泵技术领域,具体涉及一种柴电混合动力车辆用的有机朗肯循环和热泵循环耦合装置,从功能上,分为进排气通路、有机朗肯循环尾气余热回收系统、热泵循环系统、冷却液循环系统和控制系统;与现有技术相比较,本发明可减少车辆尾气排放温度,减少有害气体的排放,达到保护环境的目的;有效回收尾气排放余热,实现低品位热能的回收利用,减少燃油的消耗,实现冷热电三联供,从而提高能量利用率;通过将热泵系统的冷热源由空气改为冷却液,可拓宽热泵系统在车载环境下的宽温域使用范围;耦合系统共用换热器,可在一定程度上减少耦合装置的体积和重量,提高系统的紧凑性。
