Performance comparisons of a unitary split system using microchannel and fin-tube outdoor coils.

Author(s) : KIM J. H., GROLL E. A.

Summary

This paper investigates the performance of a unitary split system using microchannel heat exchangers instead of the conventional fin-tube designs as the outdoor coil for air-conditioning and heat pumping applications. A commercially available 3-ton heat pump with a conventional outdoor heat exchanger served as the baseline system. Performance tests were conducted with the conventional outdoor coil and after replacing the outdoor coil with custom made microchannel heat exchangers. The tests consisted of standard ARI cooling and heating/defrosting tests. The paper describes the microchannel heat exchanger configurations and presents the results obtained during the cooling and heating/defrosting tests.
