A liquid refrigerant distribution system is positioned in the housing and includes a manifold having a plurality of manifold outlet openings and a baffle positioned between the manifold and a distribution vessel and comprising a plurality of baffle openings. The distribution vessel has a plurality of distribution vessel openings for conveying the liquid refrigerant onto evaporator tubes when in use. A method of operating an evaporator includes conveying a two-phase vapor and liquid refrigerant mixture to a manifold and spraying the mixture out of the manifold through a plurality of manifold openings toward a distribution vessel. The mixture in impinged on a baffle located between the manifold and the distribution vessel and the liquid refrigerant is separated from the mixture via the impingement. The liquid refrigerant is collected at the distribution vessel.

摘要： A heating, ventilation and air conditioning (HVAC) system includes a condenser to condense a flow of refrigerant into a liquid state. The system further includes an economizer assembly having at least one separator chamber to separate liquid refrigerant from vapor refrigerant. The economizer assembly shares an upper common wall with at least a portion of the condenser and the flow of refrigerant from the condenser into the economizer assembly proceeds through a flow opening in the upper common wall. A falling film evaporator exchanges thermal energy between the liquid refrigerant and a medium flowed through a plurality of evaporator tubes in the evaporator.

The tube bundles have first and second wall members that define a tube channel, and a plurality of tubes arranged in the tube channel. Each of the first and second wall members have a first end that extends to a second end that is spaced from the refrigerant pool zone. The plurality of tube bundles is spaced one from another so as to define one or more vapor passages. A refrigerant distributor is positioned above the tube channel. The refrigerant distributor delivers a refrigerant onto the plurality or tubes toward the refrigerant pool zone.
