ShareMicrochannel components for absorption space-conditioning systems.
Author(s) : GARIMELLA S.
Summary
The paper presents the development of a miniaturization technology for heat and mass exchangers used in absorption heat pumps. Short lengths of microchannel tubes are placed in a square array, with several such arrays being stacked vertically. Successive tube arrays are oriented in a transverse orientation perpendicular to the tubes in adjacent levels. In an absorber application, the liquid solution flows in the falling-film mode countercurrent to the coolant through the tube rows. Vapour flows upward through the lattice formed by the tube banks, countercurrent to the falling solution. A preliminary model of the absorption process for ammonia-water demonstrates the potential for extremely small absorption system components. The technology is suitable for almost all absorption heat pump components.
