Heating and cooling devices, systems and related method
| DWPI Title: Heat pump for cooling and heating medium e.g. fluid in environment, has hot-side heat exchanger that is located concentrically within cold-side heat exchanger such that second blades are arranged concentrically around first blades |
| Abstract: 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. |
| Use: Heat pump for cooling and heating medium e.g. fluid in environment used in building. |
| Advantage: The rotation of the cold-side and hot-side heat exchangers reduce fouling and clogging, which facilitates extended operation at an intended or suitable heat-exchange efficiency. The heat exchangers of the heat pumps separate the liquid-phase and gas-phase refrigerant, by minimizing or eliminating the requirement of super-heating of the refrigerant vapor, when channeling the gas-phase refrigerant. The orifice size of the pressure reduction device is dynamically adjusted depending on temperature of the air flowing through the evaporator, heat load and compressor speed such that the volume of liquid in the evaporator remains at a level optimal for evaporation heat transfer. |
| Novelty: The heat pump (100a) has a compressor (140a) that compresses a refrigerant. A hot-side heat exchanger (120a) is operably connected to the compressor and configured to receive the compressed refrigerant. The hot-side heat exchanger comprises several first blades aligned radially outward from an axis of rotation of the hot-side heat exchanger. A valve is connected to the hot-side heat exchanger and receives the compressed refrigerant. A cold-side heat exchanger (130a) is operably connected to the valve and configured to receive the refrigerant. The cold-side heat exchanger comprises several second blades aligned radially outward from the axis of rotation. The cold-side heat exchanger is separate from the hot-side heat exchanger. The hot-side heat exchanger is located concentrically within the cold-side heat exchanger such that the second blades are arranged concentrically around the first blades, and the hot-side and the cold-side heat exchangers rotate about the axis of rotation. |
