Title:
RANKINE CYCLE SYSTEM
Document Type and Number:
WIPO Patent Application WO/2017/014027
Kind Code:
A1
Abstract:
[Problem] To prevent contamination of gas into a liquid pump in order to improve the pump efficiency. [Solution] This Rankine cycle system is provided, in a circulation path 2 through which a working medium circulates, with: an evaporator which uses waste heat to vaporize the working medium; an expander which extracts energy from the working medium by allowing the evaporated working medium to expand; a condenser which cools and liquefies the working medium that has passed through the expander; a receiver tank 7 which subjects the working medium that has passed through the condenser to vapor-liquid separation and discharges the liquid working medium; and a pump 3 which feeds the working medium under pressure from the receiver tank 7 toward the evaporator. The pump 3 is disposed below the receiver tank 7, and a pipe 10, which is the part of the circulation path 2 between the receiver tank 7 and the pump 3, is horizontal or is inclined downward from the receiver tank 7 toward the pump 3, over the entire length of the pipe 10.
