Is 11TR water cooled package AC Unit achievable of attaining flow of 20M vertical height?
20M of lift? Probably not from an ordinary commercial unit....The pressure loss will cause liquid refrigerant at near saturation temperature to flash as it climbs; the normal prevention is either to subcool the HP liquid well below the sat state and put a bleed arrangement near the top to get it started; or pump the liquid to a higher pressure though that requires a pretty specific vessel.
So what do we know?
11 TR...
Packaged....
A/C application...
Water-cooled...
And we want to know if this can push the water 20m up...
Well, as the limitation on the head is the pump I would say that we haven't got enough information to answer the question. Sorry.
Providing that your selected pump can handle the flow at the pressure differential the system will work OK as long as the condenser will take a water pressure of at least 2 bar.
:cool:
thanks for your guidence. actually i want to know the Airflow will reach the 20m height of 11TR Water Cooled Package AC units.
Ummmmm. Have you tried asking the manufacturer? They should have all this info to hand.
OK,
Airflow...
Not much difference compared to my last answer, apart from the fact that the height is irrelevant.
What you have to look at is the pressure losses and velocities of your ductwork, providing the fan can handle it and the ductwork is properly lagged the unit will work.
Look at the spec of the unit, you will find a value for "external static pressure", design your ductwork to comply with this and you will be OK.
:cool:
I take it you didn't like the answers you got on your previous thread then?
Nothing changed from my last answer...
The weight of the air is negotiable so height doesn't come in to it, what does is velocities and static pressures.
Correctly designed your system will work even if the ductwork has to go vertically for 100m or more, as long as the static pressure is within the limitations given by the manufacturer.
:rolleyes:
Well, that'll teach you to read the question carefully.....
