ABSTRACT
The objective was to develop a calorimetric method that allowed quick assessment of the performance of a coated heat exchange surface/fin sub-system in adsorption refrigeration, thus reducing the number of prototype constructions within any development program. The kinetics of adsorption of the working pair might be determined from the experimental results. The rig comprises a generator, an evaporator, thermoelectric modules and their corresponding control and data logging systems. Preliminary trials with the silica gel - water working pair indicated that characteristic time for mass transfer is about 15 minutes. Further work is in progress which requires calibrations, filtering and cross checking but we are optimistic that this method promises useful insight into the coated heat exchange surface/sorbent sub-system performance.
