Abstract
An absorption refrigerating apparatus of the type operating with a pressure equalizing inert gas and having an evaporative precooler for the refrigerant condensate supplied to the evaporator system of the apparatus. The evaporative precooler is constructed in a manner whereby two parallel flow paths are formed that are spaced from one another, but heat-conductively connected together. One of the flow paths is for the partial flow of weak gas while the other flow path is for the refrigerant condensate.
Claims9
In an absorption refrigerating apparatus operating with a pressure-equalizing inert gas comprising:
- an evaporative precooler having two parallel flow paths that are separated from each other by means which heat conductively connects said flow paths to one another, one of said flow paths being located below the other and forming a conduit for the condensate accumulating when said apparatus is operative, the other of said flow paths being situated at a higher level forming a conduit for the partial flow of weak gas, and means being provided for raising the condensate to said weak gas conduit and to moisten the inner wall of said weak gas conduit with said condensate, said means being a channel that extends substantially perpendicular to the longitudinal axes of said parallel flow paths.
