The present invention relates to an energy recovery system (51), which withdraws heat from a feed medium (52) containing heat energy, and—which has a heat transfer system (53) for this purpose, in order to transfer heat energy from the feed medium to a useful medium (54). According to the invention—the heat transfer system (53) has a separation system (57) which spaces apart the two media (52, 54); the heat transfer system (53) has at least one first exchanger zone (35), which allows the transfer of heat from the feed medium (52) to the useful medium (54) as long as the temperature of the feed medium is higher than that of the useful medium (54, 54′); and—the heat transfer system (53) has at least one second exchanger zone (56), which allows the transfer of heat from the feed medium (54, 54′), even when the temperature of the feed medium is lower than that of the useful medium.

A vehicle includes a powertrain having an engine and at least one controller. The controller is programmed to selectively heat at least one of a plurality of components of the powertrain with a given amount of waste heat based on an expected decrease in friction power associated with an expected increase in temperature from the given amount of waste heat for each of the components.

An in-vehicle temperature control system includes: a heater core used to heat an inside of a vehicle cabin using heat of a heat medium; a first heating unit that heats the heat medium using exhaust heat of an internal combustion engine; a thermal circuit configured to circulate the heat medium between the heater core and the first heating unit; a distribution state switching mechanism that switches a distribution state of the heat medium between a first distribution state and a second distribution state; and a control device that controls the distribution state switching mechanism, wherein: the thermal circuit includes a bypass flow path disposed in parallel with the heater core.

A heating system configured to be mounted on a motorcycle may include a food container. The heating system may further include a first coiled pipe mounted within the food container configured to heat the food container and a second coiled pipe coiled around an exhaust pipe of the motorcycle connected in fluid communication with the first coiled pipe. A working fluid may be circulated within a closed loop formed by first coiled pipe and the second coiled pipe utilizing a pumping mechanism. The working fluid may absorb heat from the exhaust pipe of the motorcycle as the working fluid flows through the second coiled pipe, and the working fluid may release the absorbed heat to the food container as the working fluid flows through the first coiled pipe.

Heat exchanger exchanging heat between coolant and refrigerant of different kinds in one device and providing an effective heat exchange ratio between the coolant and the refrigerant. The heat exchanger includes a refrigerant flow path having a refrigerant inlet and a refrigerant outlet, and a coolant flow path through which coolant flows to exchange heat with the refrigerant. The coolant flow path includes a first coolant flow path where first coolant flows, and a second coolant flow path where second coolant with a different kind flows. The heat exchanger is partitioned into a first heat exchange section, in which the first coolant exchanges heat with the refrigerant and a second heat exchange section, in which the second coolant exchanges heat with the refrigerant, so that the heat exchange in the first heat exchange section and the heat exchange in the second heat exchange are carried out independently.
