<p>Compression refrigeration apparatus (1) for removing heat from a heat load using a falling film evaporator (8), operated with an azeotropic refrigerant and utilizing a vapor-liquid separator (35), preferably inside the evaporator vessel (47). In one embodiment, two types of heat exchange surfaces (38) are utilized: one (68) for maximizing the axial distribution of refrigerant film on a heat exchange surface; the other (69) 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 (8) without redistributing the lubricant within the evaporator (8).</p> |
