Résumé

An experimental investigation was undertaken to study the performance of the bubble pump for diffusion absorption refrigeration units. The purpose of the bubble pump (besides the circulation of the working fluid) is to desorb the solute refrigerant from the solution. Therefore the efficiency of the bubble pump will be set by the amount of refrigerant desorbed from the solution. The performance of the diffusion absorption cycle depends primarily on the efficiency of the bubble pump. A continuous experimental system was designed, built and successfully operated. Experiments were performed in which some of the parameters affecting the bubble pump performance were changed. Results showed that the performance of the bubble pump depends mainly on the motive head and on the heat input to the bubble pump.
