Abstract: A thermal electric power generator includes an evaporator, an expander, an electric generator, a condenser, and a pump. A working fluid used in the thermal electric power generator is an organic working fluid. The evaporator includes a heat exchanger, a bypass channel, and a flow rate adjustment mechanism. The bypass channel allows a heat medium to bypass the heat exchanger. The flow rate adjustment mechanism adjusts a flow rate of the heat medium to be supplied to the heat exchanger and a flow rate of the heat medium to be supplied to the bypass channel.

Abstract: A thermal power generation apparatus includes a control circuit that selects a single operation mode from among a plurality of modes including a normal mode and a specific mode on the basis of a voltage in a commercial system. The normal mode is an operation mode in which alternating-current power output from an inverter is adjusted so that a direct-current voltage in a direct-current power line follows a target voltage. The specific mode is an operation mode in which direct-current power absorbed by an electric power absorber and/or the amount of heat per unit time supplied to a heat engine are/is adjusted so that the direct-current voltage follows the target voltage.

Abstract: A Rankine cycle apparatus (1A) of the present disclosure includes a main circuit (10), a heat exchange portion (HX), a bypass flow path (20), a flow rate-adjusting mechanism (3), and a pair of temperature sensors (7A). The main circuit (10) is formed by an expander (11), a condenser (13), a pump (14), and an evaporator (15) that are circularly connected in this order. The heat exchange portion (HX) is located in the main circuit (10) at a position between an outlet of the expander (11) and an inlet of the pump (14). The bypass flow path (20) branches from the main circuit (10) at a position between an outlet of the evaporator (15) and an inlet of the expander (11), and joins to the main circuit (10) at a position between the outlet of the expander (11) and an inlet of the heat exchange portion (HX). The flow rate-adjusting mechanism (3) adjusts the flow rate of the working fluid in the bypass flow path (20). The pair of temperature sensors (7A) detects temperatures of the working fluid at two positions spaced from each other in a flow direction of the working fluid.

Abstract: A Rankine cycle device in the present disclosure includes an evaporator as a heater, an expander, a cooler, a first temperature sensor, a second temperature sensor, and a control device. The first temperature sensor detects a temperature of the working fluid flowing from an outlet of the heater to an inlet of the expander in the circuit of the working fluid. The second temperature sensor detects a temperature of the working fluid flowing from an outlet of the expander to an inlet of the cooler. The controller controls a number of rotation of the expander based on a difference between a detected temperature of the first temperature sensor and a detected temperature of the second temperature sensor.
