The invention relates to the technical field of commercial vehicle heat control, in particular to a commercial vehicle air conditioner heat pump non-condensation framework which is based on the principle that a condenser and a water-cooling condenser have similar functions and functional parts with the similar functions can be integrated, the refrigerant temperature in summer is far higher than the water temperature, a refrigerant can be cooled through the water-cooling condenser, and the condensation function is achieved. In winter, waste heat of the system can be released into the water-cooling condenser, waste heat in a water path is absorbed through the evaporation heat absorption principle of a refrigerant, the condenser function is integrated into the water-cooling condenser, the condenser is omitted, and the heat pump structure is simplified. In the framework, the four-way valve is used for reversing the flowing direction of a refrigerant, and meanwhile, the refrigerating and heating requirements are met; in addition, an air conditioner system, a battery system and a motor system are integrated, so that the assembly workload is reduced by more than 60%, the number of parts is reduced, and the cost can be reduced. And finally, through thermal system integration of the whole vehicle, thermal management development is performed from the perspective of energy management of the whole vehicle, energy is absorbed from the environment and waste heat, and the endurance mileage is greatly increased.
本发明涉及商用车热控制技术领域,具体涉及一种商用车空调热泵无冷凝架构,基于冷凝器与水冷冷凝器均有相似功能,具有相似功能的功能件可集成原则,夏季冷媒温度远高于水温,通过水冷冷凝器可给冷媒降温起到冷凝功能,冬季可通过系统的余热释放到水冷冷凝器中,通过冷媒的蒸发吸热原理吸收水路中的余热,将冷凝器功能集成至水冷冷凝器中,取消冷凝器,简化了热泵架构。在架构中通过四通阀对冷媒流动进行换向,同时实现制冷制热需求;此外,将空调、电池及电机三个系统集成,使装配工作量降低60%以上,减少零部件数量还可以降低成本。最后通过整车的热系统集成,以整车能量管理的视角做热管理开发,从环境和废热中吸收能量,大幅提升续航里程。
