Abstract

The compressor or a mechanical pump of traditional refrigeration cycles is replaced by the bubble pump that circulates the binary working fluid in the diffusion absorption refrigeration (DAR) cycle. The bottleneck of the DAR cycle is the bubble pump, and its performance is determined by the amount of separated refrigerant that leaves the bubble pump. This work investigated the influence of the structure of the generator on the amount of desorbed refrigerant in a bubble pump system, with three parallel lifting tubes. Two modular experimental systems were designed to characterize the performance of three parallel bubble pump lift tubes with an environmentally-friendly binary solution of R134a-DMAC. The difference between the systems was in the design of the generator. One generator had three inlets and three outlets, and another one had a common inlet and three outlets. All other operating conditions remained the same. The results showed that an experimental system containing three inlets to the generator, produced more refrigerant than the system containing a common inlet.
