(OP)

I am seeking for the engineering equation that will tell me what size dehumidifier will be most suited for the room in question. I am appreciative of the reaction.

Exactly. I had noticed this before, but I was unsure of my understanding. I calculated and found a result of 24 kg/hr based on this calculation, but the same website gave a different value like

12 kg/hr.Space volume 2000m3

Air flow 4000 m3/hr

Airchange 4000/2000=2

Current humidity 70% at 30c(21 g/m3)

Required humidity 50%(15g/m3)

Capacity of dehumidifier = (21-15)*2000*2/1000=

24kg/hrThe problem with the world is that intelligent people are full of doubts, while stupid ones are full of confidence.

Unless you're pulling in fresh air into this unit, then you only have 2000m3 of air available to reduce the humidity.

So yes, right at the start you might be pulling 0.4kg/min, but after 30 mins you've theoretically pulled all the water out of the room no?

Think you need to see over what sort of timescale you're talking to reduce the humidity and also how many air changes are happening with the outside more humid air.
