Definitions

  • the propane is introduced into a circulating system consisting of a compressor which applies pressure to the gas and reduces it to a liquid form, and the liquid, after being suitably cooled to dissipate the heat of compression, is led to and allowed to evaporate in proximity to the material or compartment which is to be cooled, and as the evaporation takes place heat is absorbed thereby and a reduction in temperature takes place around'the point at which the evaporation.
  • a refrigerating process including compressure thereon to extract heat from .adja- 80 cent materials.
  • a refrigeration process includingcom- ,pressing' a non-acid gas having a hydrocarbon content consisting "substantially wholly of propane to liquefy the propane, and evaporating the liquidby relieving the pressure thereon to extract heat from adj acent materials.
