Dew point and humidity dilema, can you solve it?

THE FLOOD!

 

May 31st, 2011.

93 F

 

We got to the club at 3pm, opened 3 windows. Two fans were exhaust, one fan was intake.

5pm, condensation begins in the corners.

6pm, condensation is spreading

7pm, visible condensation all over the floor

8pm, this is the most ridiculous scene ever! Water everywhere.

 

So to all those interested. Ventilation is NOT the answer. Maybe if you had a windtunnel sized fan.

 

Next week we try 1 AC unit and 3 dehumidifiers.

You packed a bunch of 98F human bodies, radiating heat and emitting water vapor, into a building at 93F? Where did you expect the humidity to go exactly?

That's the whole point of the question I posted in the first place.

The people are going to come anyway, were just trying to find the best way to get rid of the water.

So check ventilation off your list, epic fail.

If you were outdoors, the ground could absorb the humidity. Maybe this is why outdoor events like circuses and concerts often have sawdust or mulch on the ground.

If you were outside there would be enough ventilation.

I'm not knocking it off the list until you try it out with lots of fresh air.

 

Why do you think there is not usually condensation on the floor?

It's because there's enough natural ventilation to remove the water.

 

A dehumidifier would kind-of-work, but think about the capacity you need.

It has to pick up water at the same rate the players lose water (as sweat and by breathing).

You have a rough idea of that rate if you look at how much water they drink. If there are 30 of them and they each drink a bottle of water an hour that's something like 15 litres of water an hour that the dehumidifiers need to shift. My guess is they drink more than that.

A big industrial dehumidifier will shift 50 litres in a day under ideal conditions. That's roughly two litres an hour. You get 3 of them and you can move 6 litres an hour (if you are lucky)

The other 9 litres an hour will end up on the floor.

 

The only practical way you can get rid of all the water is to blow it out of the window.
