Design and fabrication of a 3-D printable counter-flow/precipitation heat exchanger for use with a novel off-grid solid state refrigeration system
MetadataShow full item record
Off-grid refrigeration technologies are currently limited to either vapor-compression cycles driven by photovoltaics or solar thermal absorption cycles. Rebound Technologies has recently developed a novel off-grid refrigeration system called SunchillTM for agricultural applications in humid environments in the developing world. The SunchillTM refrigeration system utilizes the daily high and low temperatures to drive a 24 hour refrigeration cycle. Cooling is provided by the dissolution of an endothermic salt, sodium carbonate decahydrate. Once the salt is solvated and cooling is delivered to ...
