摘要： PROBLEM TO BE SOLVED: To provide a scroll expansion machine with high efficiency, while preventing a degradation of a volumetric efficiency due to disconnection of a turning scroll of scroll expansion machine. SOLUTION: In a scroll expansion machine 50, an expansion volume ratio of an expansion chamber 15 is not less than 1.0, and not greater than 1.3, as comparing between coolant density at an outlet of a radiator 8, and a coolant density at an inlet of an evaporator 9. With this configuration, a separating force at a lap side is avoided from becoming larger than a pressing force at an anti-lap side, by producing an overexpansion during operation at a low expansion ratio, so that degradation of a volumetric efficiency caused by disconnection of the turning scroll 13 from a fixed scroll 12 is prevented, and losses by insufficient expansion during normal operation due to generation of the overexpansion during operation at a low expansion ratio, is suppressed to the minimum, so that the scroll expansion machine with high efficiency is achieved.

摘要翻译：要解决的问题：为了提供一种高效率的涡旋膨胀机，同时防止由于涡旋膨胀机的转动涡卷的断开导致的体积效率的降低。解决方案：在涡旋膨胀机50中，与散热器8的出口处的冷却剂密度和冷却剂密度之间的比较相比，膨胀室15的膨胀体积比不小于1.0且不大于1.3 在蒸发器9的入口处。通过这种构造，避免了在低速膨胀比的操作期间通过产生过度膨胀使搭接侧的分离力变得大于反搭卷侧的压力，使得劣化可以防止由于涡旋盘13与固定涡旋盘12的断开而产生的体积效率，并且由于在低膨胀率的运转时由于过度膨胀而产生的正常运转时的膨胀不足的损失被抑制到最小，所以实现了高效率的涡旋膨胀机。版权所有（C）2010，JPO＆INPIT
