摘要： A falling film evaporator for use in a vapor compression refrigeration chiller preferably employs a two-phase refrigerant distributor that overlies the tube bundle in the evaporator shell. The tube bundle defines at least one vapor lane which facilitates the conduct of refrigerant vapor from the interior of the tube bundle to the exterior thereof in a manner which does not substantially affect the vertically downward flow of liquid refrigerant through the tube bundle and across the vapor lane.

摘要： Efficient two-phase refrigerant mixture distribution is accomplished in a falling film evaporator by use of a refrigerant distributor disposed internal of the evaporator shell which overlies the evaporator tube bundle and which internally causes said two-phase refrigerant mixture to be made available along essentially the entire length and across essentially the entire width of the tube bundle prior to the delivery of the refrigerant out of the distributor.

摘要： An evaporator for a refrigeration chiller includes a tube bundle in which at least a portion of the tubes of the tube bundle are immersed in a pool which include both liquid refrigerant and is lubricant. Liquid refrigerant and lubricant are deposited into the pool at a first pool location. Because of the vaporization of refrigerant that occurs within the pool, a pattern of flow is established and managed that causes the lubricant in the pool to migrate from the location of its deposit into the pool to a second pool location. An outlet is provided at the second pool location from which lubricant is drawn out of the evaporator.

摘要： Compression refrigeration apparatus for removing heat from a heat load using a falling film evaporator, operated with an azeotropic refrigerant and utilizing a spray tree distribution system that distributes a refrigerant film on a heat exchange surface by spraying liquid refrigerant onto a surface and allowing the refrigerant to drip onto the primary heat exchange surface. The apparatus allows for efficient recovery of lubricant deposited in the evaporator without redistributing the lubricant within the evaporator. In an alternative embodiment, liquid refrigerant is sprayed onto a mesh screen where it drips onto the primary heat exchange surface.
