Microchannel and finned coils: performance comparison in single phase and in condensation.

Author(s) : HANTZ D., PRA P., BENSAFI A.

Summary

The paper presents the results of tests conducted on two microchannel heat exchangers, having different fin spacings (19 and 14 FPI), for single-phase flow and condensation. Measurements included coil duty and air pressure drop. For single-phase flow, tests were carried out with chilled water on both microchannel heat exchangers, with and without moisture condensation on fins. Condensation tests were conducted with R134a and R407C on the 19 FPI microchannel heat exchanger in horizontal tube position.
