Title:
RANKINE CYCLE SYSTEM AND MANUFACTURING METHOD FOR SAME
Document Type and Number:
WIPO Patent Application WO/2020/189427
Kind Code:
A1
Abstract:
The present invention is provided with: a pressure sensor 8 disposed in a first passage 2a between an outlet 6b of an expander 6 and an inlet 7a of a condenser 7; and a plurality of temperature sensors 9 disposed apart from each other in a section with an ascending slope from the expander 6 towards the condenser 7 with respect to the first passage 2a. According to the present invention, the degree of overheating of a working fluid is calculated at the installation positions of the respective temperature sensors 9 on the basis of an acquisition value P of the pressure sensor 8 and an acquisition value T of the temperature sensors 9, the phase state of the working fluid W is estimated at the installation positions of the respective temperature sensors 9 on the basis of the calculated degree of overheating, and it is estimated that there is a liquid surface on the condensate stored in the first passage 2a in a section having, as both ends, the installation position of a temperature sensor 9 for which the estimated phase state of the working fluid W is a liquid state and the installation position of a temperature sensor 9 for which the estimated phase state is a gas state.
