Résumé

The effect of air inlet humidity condition on the air-side heat transfer and pressure drop characteristics for an inclined brazed aluminium heat exchanger has been investigated experimentally. For a heat exchanger with a louver angle of 27 °, fin pitch of 2.1 mm and flow depth of 27.9 mm, a series of tests are conducted for the air-side Reynolds numbers of 80-400, with variation of inlet humidity condition. The heat transfer data are obtained for wet condition only and the pressure drop data are measured by both dry and wet conditions. The inlet air temperature and relative humidity range are 12 °C and 60-90%, respectively. The inclination angles affect moderately the sensible heat transfer coefficient for wet condition, and the pressure drops for both dry and wet conditions increase systematically with the inclination angle. The heat transfer and pressure drop characteristics under wet condition are not influenced substantially by the air inlet humidity. The effect of the louver directions at the inlet and outlet of the inclined heat exchanger on the performance is also addressed.
