Cooling water blow system
A part of circulating water should be blown to prevent degrading of cooling water quality.
Since concentration ratio is considered about 3 to 4 blowing, water quantity is calculated as follows.
N : Concentration ratio generally N=3
M : Make-up water volume
3,024✕1.85 (exhaust factor)
E : Evaporation loss E=
575 (Latent heat of evaporation at 40°C)
W : Splashing loss generally W=0.2% of circulating water volume
B : Blow volume
E+W+B
M : E+W+B N=
W+B

Over Flow
Make-up water is over supplied
by manual valve for over-flow
in cooling tower.
Continuous Flow
Certain amount of circulating
water is blown by blow
regulation valve.
Pressure Switch+Solenoid Valve
Circulation pump is controlled
by pressure switch.
