Experimental demonstration of a prototype microchannel absorber for space-conditioning systems.

Author(s) : MEACHAM J. M., GARIMELLA S.

Summary

The absorber (19.28 kW) consists of 5 passes of 16 tube rows each with 27 1.575 mm outside diameter x 140 mm long tubes per row for a total of 2160 tubes. The resulting absorber is an extremely compact 178 mm x 178 mm by 0.508 m tall component including tube headers and the solution distribution tray. Experiments were used to determine the overall and solution-side heat and mass transfer coefficients. The results show reasonable agreement with the predictions of the model. The experiments demonstrated that high heat and mass transfer rates are achieved with this geometry, with no surface treatment or enhancement and with relatively low solution and coolant pressure drops.
