Abstract: A CHP system includes a combustor as a heat source, a Rankine cycle apparatus, a second heat exchanger, and a thermal fluid flow path. The Rankine cycle apparatus includes, as an evaporator, a first heat exchanger that absorbs thermal energy from combustion gas (thermal fluid). The second heat exchanger absorbs thermal energy from the combustion gas and transfers the thermal energy to a heat medium. The first heat exchanger and the second heat exchanger are disposed in the thermal fluid flow path. The thermal fluid flow path includes a first flow path that allows the combustion gas to reach the first heat exchanger directly from the combustor and a second flow path that allows the combustion gas to reach the second heat exchanger directly from the combustor.

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: An air cooling unit is an air cooling unit used in a Rankine cycle system and includes an expander and a condenser. The expander recovers energy from a working fluid by expanding the working fluid. The condenser cools the working fluid using air. The air cooling unit includes a heat-transfer reducer that reduces heat transfer between the expander and an air path.

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.
