DEFINITION

Classification: 62/490

(under subclass 476) Apparatus including means whereby a refrigerant is contacted with a gas which is chemically inert to the refrigerant or sorbent.

(1) Note. This system operates under a uniform total pressure with the pressure in the evaporator being the sum of the partial pressures of the inert gas and the pressure of the refrigerant vapor, i.e., it operates according to Dalton's law of partial pressures and is commonly operated by heating means for household refrigerator use.
