Title:Air-Side Heat Transfer with Highly Interrupted Surfaces: An Experimental Study of Condensate Retention Effects
Author(s):Tang, A.D.; Jacobi, A.M.
Subject(s):air-side heat transfer
condensate retention
Abstract:The effect of condensate retention on the air-side heat transfer and pressure drop performance of automotive evaporator coils was studied. Experiments under wet and dry conditions were conducted using offset strip and louver-fin heat exchangers. Condensate retention and thermal-hydraulic data were collected at steady-state to quantitatively determine how condensate accumulates and affects the heat exchanger surface. The amount of condensate retention and the thermal hydraulic performance were found to depend on fm pitch, louver pitch, louver width, fin width and contact angles.
