8.6.3 Design of the store tank in the system
kW is the unit for cooling capacity and L is the unit for G, water flow in the formula counting the minimum water flow.
Comfortable air conditioner
G= cooling capacity×3.5L
Process cooling
G= cooling capacity×7.4L
In certain occasion (especially in manufacture cooling process), for conforming the system water content requirement, it’s
necessary to mount a tank equipping with a cut-off baffle at the system to avoid water short-circuit, Please see the following
schemes:
