AirSide Parametric Investigation and Optimization of Parallel Flow Condenser

Abstract:

Within the wind speed range of automotive airconditioning condenser, the scheme of airside parametric numerical simulation for parallel flow condenser was designed by orthogonal method, and the coefficients of flow friction and heat transfer were calculated. Moreover, the effects of fin height, overturning length, fin pitch, fin width, louver pitch and louver angle on airside flow friction and heat transfer were analyzed by Taguchi method. Finally, the optimal airside parametric combination of parallel flow condenser was obtained. The results show that the fin width plays an important role in heat transfer. The effect of fin pitch on flow friction is the biggest. The fin pitch, louver angle and louver pitch of parallel flow condenser has main effect on airside performance. Overall thermalhydraulic performance improves by 4.03% to 11.09% for Re in the range of 600~1 400.
