A multi-way coolant valve and a heat pump system having the same include an external housing in which first, second and third external inlets and first, second and third external outlets are formed; and an internal housing provided rotatably inside the external housing to selectively fluidically-connect the first, second and third external inlets, and the first, second and third external outlets, and divided into two stages through which a coolant flows respectively, wherein as the internal housing rotates at a predetermined interval in a selected mode of the vehicle, the first external inlet selectively fluidically-communicates with the first external outlet, the second external outlet, or the third external outlet, the second external inlet selectively fluidically-communicates with the first external outlet or the second external outlet, and the third external inlet selectively fluidically-communicates with the first external outlet, the second external outlet, or the third external outlet.

A convector includes a rotor having a shaft extending along an axis of rotation, and a plurality of discs offset from one another along the axis of rotation and mechanically coupled to and rotatable with the shaft. The convector also includes a stator having a plurality of plates offset from one another along the axis of the shaft. Each plate of the plurality of plates defines a through-hole configured to receive the shaft and an opening configured to receive a corresponding disc of the plurality of discs. Rotation of the shaft causes each disc to rotate at least partially within the opening defined by the corresponding plate, and relative to the corresponding plate.

A pump includes a housing, a process stream input, a process stream output, a power stream inlet, and a rotor. The rotor comprises an impeller, a shroud, and a turbine. The impeller comprises fluid motive elements positioned about a central axis of the rotor and extending outward to the shroud. The turbine comprises runners formed on an outwardly facing surface of the shroud of the rotor. The shroud extends radially about the fluid motive elements of the impeller. The rotor is rotatably supported within the housing. The runners cause the rotor to rotate when the power stream flows through a fluid path impinging the runners thereby transferring energy from the flow of the power stream received through a power stream inlet into rotational energy of the fluid motive elements of the impeller to propel the process stream from a process stream input out a process stream output.
