Abstract

A cooling element of primary absorption refrigeration apparatus of the inert gas type has a temperature gradient in which the temperature progressively increases from a first temperature to a second higher temperature in an elongated path of flow in which refrigerant fluid evaporates in the presence of such gas. A secondary refrigeration system partly filled with a mixture of volatile liquids has an evaporation portion to abstract heat from the objective of cooling and a condensation portion which, along its length, is in thermal exchange relation with the cooling element. The mixture of volatile liquids forms a refrigerant fluid mixture which possesses such physical properties that the refrigerant fluids will vaporize in the evaporation portion or condense in the condensation portion or vaporize and condense in both portions, respectively, at different temperatures between the first and second higher temperatures prevailing in the cooling element. The circulation of the refrigerant fluid mixture in the secondary refrigeration system is effected solely by vapor bubbles resulting from the vaporization and boiling of the mixture of refrigerant fluids in the evaporation portion.
