|Figure 6 shows
cooling loads reduction when the source is getting higher. Note here that
stratification temperature was not set up as a same constant. Rather, the
supply temperature and flow rate are same and cooling loads are different so
that the temperature at the stratification level are different. Therefore we
have to be careful in interpretation of Fig. 6. This fact implies that in
case3, if we set up the temperature @y=1.5m higher than 23C, we could reduce
the flow rate to achieve cooling.
