WASTE HEAT UTILIZATION DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a small waste heat utilization device which has a large available output. SOLUTION: The waste heat utilization device includes: a tank 2 that stores a working fluid in a state of a liquid s; a pump 3 that pressurized and delivers the working fluid s from the tank 2; an evaporator 4 that generates a vapor g by evaporating the working fluid s from the pump 3; an expander 5 that expands the vapor g from the evaporator 4 and converts the expansion power into rotative power; and a condenser 6 that cools and condenses the vapor g from the expander 5 to obtain the liquid s and return the liquid s to the tank 2. The waste heat utilization device also includes: a tank pressurization line 8 that supplies part of the vapor g between the evaporator 4 and the condenser 6 to the tank 2 and pressurizes inside the tank 2. A flow rate control means 9 is disposed in the tank pressurization line 8 so as to control a flow rate of the vapor g supplied to the tank 2. COPYRIGHT: (C)2011,JPO&INPIT
