ABSTRACT:
Compression refrigeration apparatus for removing heat from a heat load using a falling film evaporator, operated with an azeotropic refrigerant and utilizing a vapor-liquid separator, preferably inside the evaporator vessel. In one embodiment, two types of heat exchange surfaces are utilized--one for maximizing the axial distribution of refrigerant film on a heat exchange surface, the other for encouraging liquid refrigerant in contact with a heat exchange surface to boil and evaporate. The apparatus allows for efficient recovery of lubricant deposited in the evaporator without redistributing the lubricant within the evaporator.
