Re: Calculating Reheat Capacity - For Humidity Control
Physchrometric chart the condition change is almost a straight line so I'm confused.

Re: Calculating Reheat Capacity - For Humidity Control
Yes, this straight line is under the assumptions that air picks up internal room loads, and achieves this set point. But what happens if there are no internal loads?

Re: Calculating Reheat Capacity - For Humidity Control
I am not an HVAC guy, so consider this a question more than a comment.
If the conditioned space is at the required temp why cool the air going into it?

Re: Calculating Reheat Capacity - For Humidity Control
Good thought. The reason is again high RH. The space needs to be pressurized, hence I need some percentage of fresh air supply through out the year. This fresh air will causes varying RH (sometimes very high during winter and rain). To control these, and to meet the design RH set point of 50%, I need the chillers to be functional through out. . .
