TECHNICAL AND ECONOMICAL EVALUATION OF SUBSTITUTING SHELL & TUBE HEAT EXCHANGERS WITH MULTISTREAM PLATE FIN HEAT EXCHANGERS IN HEAT RECOVERY NETWORKS

heat, transfer between more than two streams in a single unit. They are used where high performance and low weight are required. The main applications of this kind of heat exchangers arc in cryogenic gas pro­cessing as main feed pie-cooleTs, condensers and liquid chillers, in aerospace industry as oil and fuel coolers, ra­diators and in HVAC industry as air to air exchangers, condensers and evaporators. High thermal performance and economical advantages make them suitable to be used in heat recovery networks instead of shell fe tube heat exchangers. In the current, paper, the thermal design of the Multi-stream Plate fin heat exchangers will be mentioned and the economical and technical results of replaciug shell & tube heat ex­changers by Multi-stream Plate fin heat exchangers in a heat recovery network will be inspected.
