Heating and cooling devices, systems and related method
Embodiments disclosed herein relate to devices, systems, and methods for cooling and/or heating a medium as well as cooling and/or heating an environment containing the medium. More specifically, at least one embodiment includes a heat pump that may heat and/or cool a medium and, in some instances, may transfer heat from one location to another location.
1. A heat pump, comprising:
a compressor configured to compress a refrigerant;
a hot-side heat exchanger operably connected to the compressor and configured to receive the compressed refrigerant therefrom, the hot-side heat exchanger comprising a first plurality of blades aligned radially outward from an axis of rotation of the hot-side heat exchanger;
a valve that is connected to the hot-side heat exchanger and that receives the compressed refrigerant therefrom; and
a cold-side heat exchanger operably connected to the valve and configured to receive the refrigerant therefrom, the cold-side heat exchanger comprising a second plurality of blades aligned radially outward from the axis of rotation, the cold-side heat exchanger being separate from the hot-side heat exchanger, wherein the hot-side heat exchanger is located concentrically within the cold-side heat exchanger such that the second plurality of blades are arranged concentrically around the first plurality of blades, and the hot-side heat exchanger and the cold-side heat exchanger rotate about the axis of rotation.
2. The heat pump of claim 1 , further comprising:
a connecting conduit, wherein the connecting conduit is located at the center of the hot-side heat exchanger, along the axis of rotation;
a drive shaft, a first end of the drive shaft is coupled via the connecting conduit to the heat pump; and
a motor mounted on a motor mount, wherein the motor is connected to a second end of the drive shaft, the motor being configured to rotate the hot-side heat exchanger relative to the motor mount, wherein rotatable motion of the hot-side heat exchanger confers rotatable motion to the cold-side heat exchanger causing the cold-side heat exchanger to rotate in unison with the rotation of the hot-side heat exchanger.
3. The heat pump of claim 2 , the first plurality of blades having channels formed therein, the second plurality of blades having channels formed therein, the heat pump further comprising:
a first channel located between the connecting conduit and the first plurality of blades;
a second channel located between the first plurality of blades and the second plurality of blades; and
a third channel located at an exterior edge of the cold-side heat exchanger, and connected to the second plurality of blades and the compressor, the compressor is connected to the connecting conduit, wherein during rotation of the heat pump, refrigerant flows from the compressor, through the connecting conduit, through the first channel, through the first plurality of blades, through the second channel, through the second plurality of blades, through the third channel, and returns to the compressor for subsequent re-conveyance of the refrigerant through the heat pump.
4. The heat pump of claim 3 , wherein the second channel is formed from a condenser wall and an evaporator wall, wherein the condenser wall forms an exterior surface of the hot-side heat exchanger and the evaporator wall forms an interior surface of the cold-side heat exchanger, the condenser wall being located closer to the first channel than the second channel;
the condenser wall includes a first opening, and the evaporator wall includes a second opening, wherein the first opening and the second opening are co-aligned about a second axis perpendicular to the axis of rotation;
the heat pump further comprising:
an actuator that is configured to move in an axial and/or azimuthal direction relative to the axis of rotation, wherein movement of the actuator is based upon a magnitude of hydrostatic pressure of a liquid that accumulates in the third channel during rotation of the heat pump; and
a channel structure located between the condenser wall and the evaporator wall, wherein the channel structure includes a third opening, where the third opening is positionable by the actuator to be coaxially aligned with or offset from the first opening and the second opening.
5. The heat pump of claim 4 , wherein the channel structure comprises a closed cell foam or a polymer.
6. The heat pump of claim 4 , wherein the channel structure comprises a compressible material, wherein compression of the compressible material resulting from motion of the actuator causes the third opening to at least one of reduce in size or change position relative to the first opening and the second opening.
7. The heat pump of claim 3 , the second plurality of blades include a hollow blade, wherein a channel is positioned inside the hollow blade, the channel includes a plurality of shelves, wherein the plurality of shelves are configured to capture liquid phase refrigerant.
8. The heat pump of claim 1 , wherein the compressor comprises:
a rotational component, wherein the rotational component is configured to rotate at a same speed of rotation as the heat pump;
a second component, which is configured to engage with the rotational component, wherein the second component undergoes relative motion compared to the rotational component;
a shaft connected to the second component, wherein rotation of the shaft causes the second component to move relative to the rotational component;
an internal magnet located on the shaft; and
an external magnet, wherein the rotational speed of the shaft can be adjusted by motion of the external magnet about the axis of rotation.
