Compact Wetland System for Washrack Effluent

Not Available The objective of this effort is to determine the feasibility of designing, fabricating and testing a sensor cooler which uses solid materials as the refrigerant. These materials demonstrate the unique property known as the magnetocaloric effect, which means that they increase and decrease in temperature when magnetized/demagnetized. This effect has been observed for many years and was used for cooling near absolute zero. Recently, materials are being developed which have sufficient temperature and entropy change to make them useful for a wide range of temperature applications. The proposed effort includes magnetocaloric effect material selection, analyses, design and integration of components into a preliminary design. Benefits of this design are lower cost, longer life, lower weight and higher efficiency because it only requires one moving part - the rotating disk on which the magneto caloric material is mounted. The unit uses no gas compressor, no pumps, no working fluid, no valves, and no ozone-destroying chlorofluorocarbons/hydrochlorofluorocarbons (CFC's/HCFC's). Potential commercial applications include cooling of electronics, superconducting components used in telcommunications equipment (cell phone base stations), home and commercial refrigerators, heat pumps, air conditioning for homes, offices and automobiles, and virtually any place that refrigeration is needed.
