Abstract: A CHP system includes a combustor (heat source), a Rankine cycle apparatus, and a second heat exchanger. The Rankine cycle apparatus includes, as an evaporator, a first heat exchanger that absorbs thermal energy produced in the combustor. The second heat exchanger is located farther from the combustor than is the evaporator, is in direct contact with the evaporator or in indirect contact with the evaporator via a thermally-conductive member, absorbs thermal energy produced in the combustor, and transfers the thermal energy to a heat medium.

Abstract: A rotary compressor (100) includes a closed casing (1), a cylinder (15), a piston (28), a lower bearing member (7), a vane (33), a suction port (20), a discharge port (41), and a partition member (10). The partition member (10) is attached to the lower bearing member (7) so as to form a refrigerant discharge space (52) serving as a flow path of a refrigerant discharged from a discharge chamber (26b) through the discharge port (41). The lower bearing member (7) is provided with a first recess (7t) on the same side as the suction port (20) with respect to a reference plane, the reference plane being a plane including a central axis of the cylinder (15) and a center of the vane (33) when the vane (33) protrudes maximally toward the central axis of the cylinder (15). A portion of oil stored in an oil reservoir (22) flows into the first recess (7t), and thereby an oil retaining portion (53) is formed.

Abstract: A Rankine cycle apparatus includes a pump, an evaporator, an expander, a condenser, and an internal heat exchanger. The internal heat exchanger allows heat exchange to take place between a working fluid discharged from the expander and a working fluid discharged from the pump. A temperature of the working fluid at an inlet of the expander is set so that a temperature of the working fluid at an outlet of the expander be higher than a saturation temperature on a high-pressure side of the cycle.

Abstract: A Rankine cycle apparatus includes a pump, an evaporator, an expander, and a condenser. The evaporator has a plurality of heat transfer tubes arranged in rows in a flow direction of a high-temperature fluid to be heat-exchanged with a working fluid. The heat transfer tube located in a most upstream row in the flow direction of the high-temperature fluid is defined as a most upstream heat transfer tube. For example, the most upstream heat transfer tube forms an inlet of the evaporator so that the working fluid flows into the evaporator through the inlet and first passes through the most upstream heat transfer tube.

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 fin-and-tube heat exchanger comprises: fins (31) which each have flat sections (35), first sloped sections (36), and second sloped sections (38); and heat transfer pipes (21). If a flat plane which is in contact, from the side opposite the crest of a ridge (34), with the upstream end and downstream end of the first sloped sections (36) in the air flow direction is a reference flat plane (H1), the angle between the reference flat plane (H1) and each of the second sloped sections (38) measured in a region upstream of a through-hole in the air flow direction is θ2, then the range of θ2 is determined by the relationship 0°
