Résumé

Plate heat exchangers have been widely used in dairy, food processing, paper/pulp, heating, ventilating, and other related industry. While single-phase flow in plate heat exchangers has been studied extensively, the industry lacks basic information on fluid flow evaporating in plate heat exchangers. This paper provides a review of heat transfer and pressure drop correlations for fluid flow evaporating in plate heat exchangers. Emphasis is placed on the application of a plate heat exchanger as an ammonia evaporator in a refrigeration system. It is shown via thorough research of related thermal-hydraulic phenomena that heat transfer and pressure drop correlations are needed for liquid ammonia flow evaporating in plate heat exchangers. The effects of plate geometry, plate material, oil/lubricant concentration, and several operating parameters on heat transfer coefficient and pressure drop for plate heat exchangers also need to be quantified.
