Module welded plate heat exchanger within the NH3 refrigeration circuit: effective technique for using at flooded and dry-expansion applications.

Author(s) : DIETRICH W.

Summary

The paper summarizes the principle in the fundamental operation of a laser welded plate heat exchanger (PHE). After having discussed the advantages of the PHE compared with other types of heat exchangers, the special adaptations for applications of the exchanger in commercial and industrial refrigeration are described. The author then mentions the facts that have to be considered in the material selection depending on the purpose of the PHE within the refrigeration circuit. The lecture is focused on the description and evaluation of the used PHE as a flooded evaporator in view of its particularities and its limits of application. The use of the module welded PHE as a DX evaporator within NH3 circuits of higher heat loads is reflected closely.
