Abstract


This work is the first step in the development of an electric field refrigeration unit. Cooling devices in the future may lose their compressor and coils of piping to become solid state. Refrigerators or air conditioners — rely on the properties of gases to cool and most systems use the change in density of gases at changing pressures to cool. The coolants commonly used are either harmful to people or the environment. Freon, one of the fluoro chloro carbons banned because of the damage it did to the ozone layer, was the most commonly used refrigerant. Now, a variety of coolants is available. Nevertheless, all have problems and require energy-eating compressors and lots of heating coils. We designed and constructed a COMPRESSOR LESS PELTIER REFRIGERATOR with an interior cooling. The Peltier refrigerator was equipped with on/off control which was found to be adequate to meet the required precision of +/- 15 degrees Celsius put forth in the work requirements.
