f
If the length of water pipe is too short, water storage
within the system becomes lower and ON/OFF
operation of the compressor occurs more often. For
stable operation, maintain certain water storage by
applying header or Buffer tank.
CAUTION
ŷ
When installing tank, inlet pipe of the tank must be
installed under the water level.
f
If total water storage becomes under the minimum
storage, install another tank to retain more water
storage.
- In case of variable flow system, retain certain
amount of water by bypass pipe system.

NOTE
ŷ
Total water storage in the system = water storage
within the water pipe + water storage in DVM
C water storage in AHU (or fan coil)

Minimum capacity of buffer tank = Minimum
water storage - Total water storage in the system
excluding buffer tank
ŷ
Select the capacity of buffer tank according to
system installation condition of the field.
