    • The present invention provides devices and methods for obtaining mechanical, electrical and cooling power from a high temperature heat source (80), which maybe intermittent, and an ambient temperature heat source (130). In one embodiment of the invention, the working fluid (100) passes through a fluid circuit including a first vaporizer (10), an expansion device (30) for providing useful mechanical power from the vaporized liquid, a first heat exchanger (40) for cooling the high pressure vaporized liquid, a reservoir for collecting (50), by gravity, the high pressure vaporized liquid, a first valve (60) leading to a second heat exchanger (260), which may or may not be necessary, leading by gravity flow to a second valve (70), allowing the cool, low pressure liquid to drain back by gravity to the first vaporizer. In this embodiment, the first vaporizer is heated by a high temperature heat source, and the expansion device provides mechanical power to an electric generator.
    • 本发明提供了用于从可能间歇的高温热源(80)和环境温度热源(130)获得机械,电和冷却功率的装置和方法。 在本发明的一个实施例中,工作流体(100)通过包括第一蒸发器(10),用于从汽化液体提供有用的机械功率的膨胀装置(30)的流体回路,第一热交换器(40) 冷却高压蒸发的液体,用于通过重力收集(50)高压汽化液体的储存器,通向第二热交换器(260)的第一阀(60),其可以或可能不是必需的,由第 重力流向第二阀(70),允许冷却的低压液体通过重力排回第一蒸发器。 在本实施例中,第一蒸发器由高温热源加热,膨胀装置向发电机提供机械动力。
