Residual heat utilization device for recovery of mechanical energy from low-grade thermal energy, comprises evaporation chamber, which is connected with heat source, and hydraulic machine for driving working fluid

摘要

The residual heat utilization device (1) comprises an evaporation chamber (3), which is connected with a heat source (2), and a hydraulic machine (5) for driving the working fluid. A hydraulic pump (6) is provided, which has a buffer volume (4) provided as a heat sink for the working fluid. A control unit is provided for controlling the flow of working fluid from the evaporation chamber by the hydraulic machine in the buffer volume.
