Module integration in an adsorption cooling system

Abstract A numerical analysis was conducted to estimate the system performance of an adsorption cooling chiller composed of multi-modules. Each module was composed of multi-tubes and each tube was composed of hundreds of fins. To accurately estimate system performance, a new approach was suggested, involving a full scale analysis of one tube. Also an examination of system integration depending on the arrangement of the modules was conducted. Two factors, i.e., (i) temperature drop in the serial arrangement and (ii) reduced flow rate in the parallel arrangement, compete, and ultimately a combined serial-parallel arrangement gives the highest overall system performance. The obtained system performance of COP and SCP were much lower than those modeled with one fin pitch space, the method normally used in previous studies, whose results always over-estimated the system performance compared to experiments.
