dear all
we have a 70TR water cooled water chiller installed in an particle board industry to cool down the machines.in pakistan we have a svere load shedding problem.therefore if chiller turned off for some time the chilled water temprature becomes 40 to 45 deg c.for chiller it is very difficult to overcome this temprature.therefore i want to use a buffer zone in the chilled water circut.a 10*4*15cft underground water tank is available to me.i want to cool down the water tank and using this water tank i want to cool down the machines.in this way underground water tank will act like a buffer zone.

my approach is ok or having some problem?
