Matthew D. Determan, Auteur ; Srinivas Garimella, Auteur |This paper presents the results of an experimentally validated model for the prediction of local heat and mass transfer rates in a microchannel ammonia–water desorber. The desorber is an extremely compact 178 mm × 178 mm × 0.508 m tall component[...]

Akhil Agarwal, Auteur ; Todd M. Bandhauer, Auteur ; Srinivas Garimella, Auteur |Heat transfer coefficients in six non-circular horizontal microchannels (0.424 < Dh < 0.839 mm) of different shapes during condensation of refrigerant R134a over the mass flux range 150 < G < 750 kg m−2 s−1 were measured in this study. The c[...]

Microchannel component technology for system-wide application in ammonia/water absorption heat pumps
Srinivas Garimella, Auteur ; Matthew D. Determan, Auteur ; J. Mark Meacham, Auteur |A novel miniaturization technology for binary-fluid heat and mass exchange was developed and numerous components were fabricated for demonstration as different parts of an ammonia/water absorption heat pump. Short lengths of microchannel tubes a[...]
