Résumé

The performances of three types of heat exchangers that use the louver fin geometry: 1) parallel flow parallel fin with extruded flat tube heat exchanger; 2) parallel flow serpentine fin with extruded flat tubes heat exchanger; and 3) round tube wave plate fin heat exchanger have been experimentally studied under dry, wet and frost conditions and results are presented. The parameters quantified include air-side pressure drop, water retention on the surface of the heat exchanger, capacity and overall heat transfer coefficient for air face velocity 0.9, 2 and 3 m/s, air humidity 70 and 80% and different orientations. The performances of three types of heat exchanger are compared and the results obtained are presented. The condensate drainage behaviour of the air-side surface of these three heat exchanger types was studied using both the dip testing method and wind tunnel experiment.
