AT-96-19-3 -- Testing of a Hydrocarbon Mixture in Domestic Refrigerators PDF

Describes an investigation of a propane/isobutane (R290/R600a) mixture in domestic refrigerators. Notes the instrumentation and gives the test results. Finds that, compared to R12, the mixture showed a 3% to 4% increase in energy efficiency and a faster cooling rate, a shorter compressor on-time and flow compressor dome temperatures. Concludes that the mixture seems to be an appropriate candidate to replace R12 from the viewpoint of energy conservation.
