A HEATING, VENTILATION, AIR CONDITIONING, AND REFRIGERATION (HVACamp;R) SYSTEM HAVING AN EVAPORATOR WITH A MESH ELIMINATOR ASSEMBLY, AND A METHOD OF CONSTRUCTING A MESH ELIMINATOR ASSEMBLY

摘要

A falling film evaporator including a one-piece shell having a plurality of heat exchange tubes disposed at least partially underneath a hood. The falling film evaporator includes a mesh eliminator assembly disposed within a shell to block liquid carryover. The mesh eliminator assembly includes a support structure having a first channel element extending axially within the shell and coupled to an inner surface of the shell, and having a second channel element extending axially within the one-piece shell and coupled to the hood of the falling film evaporator. The mesh eliminator assembly includes a mesh element having one or more layers of a metal mesh disposed within the support structure, and a grid plate disposed within the support structure beneath the mesh element to support a lower surface of the mesh element and having openings of a larger dimension than openings of the metal mesh.
