An Alfa-Laval plate heat exchanger, previously used as the Mini-OTEC evaporator, was refurbished and tested in the Argonne National Laboratory (ANL) heat-exchanger test facility. Several series of tests were carried out with ammonia as the working fluid, followed by one with Freon 22. Configurations utilizatng all high angle plates and all low angle plates, and alternate high and low angle plates, were tested to determine the optimum combination for OTEC applications. The effects of ammonia contaminated by water on the thermal performance of the heat exchanger were evaluated. The use of the Linde High-Flux Surface on the working-fluid side of a Transfer plate heat exchanger was investigated to determine its effect on performance.
