The Effect of Zeolite Adsorbent Granular Size on Solar Adsorption Chiller for Universitas Indonesia Area

Nasruddin Nasruddin, Dicky Alamsyah, Jeremy Ericsson



Cooling systems in
tropical countries consume a large portion of the overall energy usage in a
building, especially in tropical climates, where there is an especially high
demand on cooling systems throughout the year. This paper presents a simulation
of the effect of zeolite adsorbent granular size on a zeolite-water solar adsorption
chiller for Universitas Indonesia. The adsorption chiller is being
mathematically modeled and calculated numerically, using MATLAB®. The
mathematical modeling is based on heat transfer principles inside the system
for the water inlet and outlet of the system. The adsorption chiller is based
on the most recent chiller developed by Shanghai Jiao Tong University (SJTU).
The simulation results generally demonstrated the running characteristics of
the chiller under a range of different values of granular size. The average
granular sizes used in the simulation ranged from 0.5 mm to 1.5 mm.
Furthermore, the simulation results showed in detail that the smaller the
average granular size of zeolites, the faster the time needed to reach the
maximum hot water temperature and the balance state of chilled water outlet
