Resumen:
An experimental investigation of an air-cooled diffusion absorption machine operating with a binary light hydrocarbon mixture (C4H10/C9H20) as working fluids and helium as pressure equalizing inert gas is presented in this paper. The machine, made of copper an available and very good heat conducting metal, is intended to be solar powered heat from flat plate or common evacuated tube collectors. The cooling capacity is 40-47 W respectively for 9 and 11°C chilled water temperature. Cold is produced at temperatures between -10 and +10 °C for a driving temperature in the range of 120-150 °C. © 2009.
