Abstract

This study presents comparison of the air side heat transfer and friction characteristics in a heating condition between Louver fin-tube heat exchangers and aluminum heat exchangers. Experiments are performed for the Louver fin-tube heat exchangers and aluminum heat exchangers using a calorimeter, which is designed based on air-enthalpy method described in ASHRAE standards. The air velocities its are varied from 0.7 to 1.6 m/s with 0.3 m/s interval. A study result shows that the heat transfer performances of aluminum heat exchangers are $40{\sim}80%$ higher than those of Louver fin-tube heat exchangers per unit volume, mass and heat transfer area.
