Abstract:
This thesis deals with the perfonnance investigation of a silica gel! water-base,ltwQstage
ad'(}rption chiller empl(}ying re-heat scheme with different mass ratios and
compared with that of the l'.vo-stage conventional chiller with re-heat scheme ming
equal maSS allocation (npper bed: lower bcd = 1:1). The performance ofa lwo-stage
ad,(}rpli(}nchiller using re-hea! scheme wilh different mass allocation between "pper
and lower bed, have been investigated numerically. Results show [hat cooling capacily
can be improved with the optimum allocat1on of adsorbent maSSto the upper beds than
that of lower bcds. The improvcment in Co-efficient of Performance (COP) val"es.
however, is less significant. It is also seen that the improvement in cooling capacity lS
more significant for the relatively higher heat source temperature. It is shown that lh~
cooling capacity can be improved lip to 8';', if lhe heat source lemperature is 80°C.
