摘 要 ：以减少氨系统注氨量为目的,通过与常规氨系统气液分离设备：低压循环贮液桶和氨液分离器的比较，设计了新型的低压循环贮液桶和新型氨液分离器：采用变径筒身的设计，使两大设备在不改变其基本功能的前提下，大大减小设备的注氨量，达到减小系统注氨的目的。 关键词 ：氨制冷系统 注氨量 低压循环贮液桶 氨液分离器 变径筒身 The New Design Of Flash Chamber To Reduce The Ammonia Injection Volume In Ammonia Refrigeration Systems Li Min Dai Wuzi Li Zhan Engineering College, Guangdong Ocean University, Zhanjiang, 524001, China Abstract: Comparing with conventional flash chamber of ammonia systems : low-pressure circulation receiver and ammonia flash chamber , introduce a new type of low-pressure circulation receiver, and a new type of ammonia flash chamber: By changing diameter of canister , the two devices greatly reduces the amount of ammonia injection without changing its basic functions, and achieve the purpose of reducing the ammonia injection volume of system . Keywords :Ammonia refrigeration system Ammonia injection volume Low-pressure circulation receiver Ammonia flash chamber Adjustable diameter of canister 参 考 文 献 [1] Andy Pearson.
