System minimum water volume:
It is often necessary to add a buffer water tank to the circuit in order to achieve the required water
volume. The tank itself must be internally baffled in order to ensure proper mixing of the liquid (water or
brine). Water tank volume is large than 1 / 10 whole system water volume at least.
Refer to the examples below.
How to calculate minimum volume in pipeline system:
W=QgT/CP▽t
W — Minimum water volume（kg）；
Qg — Total cooling/heating capacity of the terminal（kW）；
T — Thermal stability time requirement，Take（8～10）×60s；
CP — Water specific heat at constant pressure，4.187kj/（kg·℃）；
▽t — Water temperature fluctuation required value，take 5℃。
