According to 5.10.1 you should have a relative humidity of no more than 65%. And you have to analyze this with outdoor air at humidification design conditions (design dew point and mean coincident dry bulb) with the space interior loads both sensible and latent, and space solar loads at zero. Although this make sense, how can you document compliance with this article???? Is there a computer program that can do this?? I've been trying to find an answer with Carrier HAP, without luck.
Any guidance in regards.
Thanks.

This should be analyzed using a psychrometric analysis program, where you can plot state points on an electronic psychrometric chart. Alternatively, you can use a traditional graphical approach on a paper copy of a psychrometric chart. This analysis is difficult to achieve with either Carrier HAP or Trane Trace. I believe you meant the dehumidification condition, rather than the humidification condition in your message?

Thanks Roger. Yes it is possible to do it with HAP, I contacted them and they explained to me how to do it. Yes, my bad, I meant DH.
