Definitions

  • This invention relates to the art. of refrigeration. 7
  • the general object of the invention is to providean improved system of refrigeration which will enable the production of greater refrigera-v tion, effect with existing equipment than is now obtained by dichlorodifiuoromethane hereinafter called by its trade-name F12.
  • Another object is to provide a refrigerant for use with a compressor serving a refrigeration system so that when said compressor is driven by .a motor servedby 50 cycle current, refrigeration effect will be produced substantially equivalent to that obtained by F12 in such system with the motor served by 60 cycle current.
  • a further object is to provide a refrigerant which will produce an evaporating temperature approximately to 15 lower than that obtained .irom the use of F12 in the same refrigeration system operated at the same condensing temperature.
  • Another object is to provide a refrigerant which will, increase the capacity of .a given refrigeration system approximately 12% when employing driving elements of given size for the compressor ofthe system over that possible of attainment with the use of F12 in the same system.
  • Another feature of the invention is the provision or a refrigerant mixture adapted for use inequipment designed specifically for the chief component of the mixture which enables the equipment to provide substantially the same refrigeration capacity even when operated at a substantial decrease in the number of revolu tions per minute.
  • a refrigerant comprising a vapor and a liquid in equilibrium with one another, the composition of said vapor being the same as the composition of said liquid, said refrigerant consisting of an azeotropic mixture of dichlorodifluoromethane and methyl chloride having a boiling point of approximately 32 F. at 50 p. s. i. a. and containing approximately 78.5
