以废气能量为动力的吸收式运输制冷机（ATR）可以为冷藏拖车提供受控的低于环境的环境，使用的燃料比当前技术少得多。ATR利用吸收式制冷循环，主要由运输车辆（卡车）发动机的废热提供动力。制冷系统（通常由一个装有柴油压缩机的小型蒸汽压缩机组成）由一个小型压缩机驱动。这些系统的容量范围为20000至50000 Btu/h（5.9-14.6 kW）。完成了废气热交换器（EGHX）和板翅式液力加热氨蒸汽发生器的概念验证试验。EGHX必须能够从气流中去除大量能量，而不会产生巨大的压力损失损失（这将降低卡车发动机的效率），并且可以轻松安装在大型半挂车的排气系统中- 卡车发电机必须能够利用可用的废能流产生尽可能多的蒸汽，以尽量减少所需的辅助热量，同时保持良好循环性能所需的溶液温度和浓度曲线。虽然专门为运输制冷设计，但本项目期间开发的技术可应用于任何需要制冷的应用，在这些应用中，高温废热流（固定发动机驱动冷藏仓库中的冷却器或提供当地电力、工业流程等）是可用的。EGHX可以作为独立的热回收设备应用于任何应用。水力加热发电机是太阳能制冷的理想选择。单位:双引文:研讨会，ASHRAE交易，第109卷，第。1.

An exhaust energy-powered absorption transport refrigerator (ATR) can provide a controlled, below ambient environment to a refrigerated trailer using significantly less fuel than current technology. An ATR utilizes an absorption refrigeration cycle that is powered primarily by waste heat from the transport vehicle (truck) engine. Current technology utilizes a vapor-compression refrigeration system consisting of a trailer-mounted refrigeration unit with the compressor driven by a small combustion engine (typically diesel). Capacities of these systems range from 20,000 to 50,000 Btu/h (5.9-14.6 kW).Proof-of-concept testing on an exhaust gas heat exchanger (EGHX) and a plate-fin, hydronically heated ammonia vapor generator was completed. The EGHX must remove a large amount of energy from a gas stream without a large pressure loss penalty (which would reduce the efficiency of the truck engine) and be easily installed in the exhaust system of a large semi-truck. The generator must be able to generate as much vapor as possible, using the available waste energy stream, in order to minimize the amount of auxiliary heat required and do so while maintaining the solution temperature and concentration profiles required for good cycle performance.While designed specifically for transport refrigeration, the technology developed during this project can be applied to any application requiring refrigeration in which a high-temperature waste heat stream (stationary engines driving chillers in refrigerated warehouses or providing local electrical power, industrial processes, etc.) is available. The EGHX could be applied as a stand-alone heat recovery device for any number of applications. The hydronically heated generator is ideal for solar-powered refrigeration.Units: Dual
