Abstract
The ability of granular activated carbon (GAC) to adsorb
large mass of refrigerant gases makes it ideal for use in thermal
compressor. In order to make thermal compressor economically
viable, the size must be reduced and for that reason thermal
responses should be increase as much as possible during heating
and cooling process. This paper investigates the effect of GAC
bed density on the thermal transient responses when a sudden
change in temperature is imposed on wall of a test sample reactor.
The test sample consists of 1” OD stainless steel with 0.71 [mm]
thickness and 200[mm] length that is loaded with compacted
granular activated. The granular carbon used is 208C (coconut
shell base) with 13×30 mesh size and provided by ‘Chemviron
Carbon Company’. To find the heat transfer coefficient of the
contact wall/packed carbon (h) and packed bed thermal
conductivity (k) a numerical inverse heat conduction method is
used in conjunction with an iterative process based on
minimizing the Mean Square Error (MSE) from measured
temperatures. Experimental work is carried out by measuring the
wall and centre temperatures of submerged sample in a
temperature controlled water bath at around 85 [oC]. Five
samples with the packed bed density ranging from 500 [kg/m3] to 800 [kg/m3] were tested and the results show a quasi-linear
increase of both thermal conductivity (k) and heat transfer
coefficient of the contact wall/packed carbon (h) with the packed
bed density: 0.15 [W/m.K] < k < 0.45 [W/m.K] and 150 [W/m2.K] < h < 1400 [W/m2.K].
