Head pressure control in evaporating condensers
Hi everybody,
I have not worked with evaporative condensers so I don't have any experience.
Someone told me today that for head pressure control they turn the fans on and off. So far so good...
Then I was told that they use one (1) hi pressure switch and a timer (???). When pressure goes down then HP switch breaks the circuit of first fan and then activates the timer. After say, 60 s if pressure does not go up then second fan is turned off.
Now My question is this : Why use a timer?
Can anybody explain if this method is correct and if so why timer?
Thanks a lot.
