Abstract
A prototype multi-bed regenerative adsorption chiller with a novel four-bed operation mode has been designed, fabricated and tested. The rating tests are conducted under assorted ARI coolant, using a purpose-built rating. The 4.bed design exhibits superior heat extraction capability from the heat source as its "slave-first-then-master" arrangement permits individual bed to maximize energy utilization in a batch cycle. Overall system performance of chiller is evaluated for various adsorption-desorption cycle and switching time at assorted coolant inlet temperatures. For fair comparison, the 4-bed chiller is also compared with that of a two-bed mode at the same working conditions.
