Résumé

The performances of three types of heat exchangers that use the louver fin geometry: 1) parallel flow parallel fin with extruded flat tubes heat exchanger (PF2); 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 changer, capacity for air surface velocity 0.9, 2 and 3 m/s, air humidity 70 and 80%. The performances of three types of heat exchangers are compared and the results obtained are presented. The primary goal of this project is to explore the thermal hydraulic performance of PF2 heat exchanger in refrigeration and heat pump systems. Using both the dip testing method and wind tunnel experiment assess the condensate drainage behaviour of the air-side surface of these three heat-exchanger types.
