摘　　要：喷射器是一种有效利用系统中膨胀过程损失的能量的节能技术。我们曾开发了用于大型冷冻车的整体式冷冻机喷射系统。现在我们又开发出不需要气液分离器的第二代喷射系统,这一新系统可以应用于小型货车的分体式冷冻机。此新系统显著提高了COP且具有更好的制冷性能。Ejector is an energy conservation technology that can effectively use energy, which had been lost during the expansion process in the conventional system. We developed ejector system for packaged -type refrigerators for largesized trucks. We have developed the 2^nd generation ejector system, which can eliminate an accumulator, so that we could apply this new system to the separate - type refrigerators for small truck use. The new system has significantly higher COP （coefficient of performance） than current ones, as well as having higher cooling capacity.
