[EnergyPlus_Support] Re: Simplest way to control RH in a zone
Thanks you Vaibhav,
Your method in point 3 inspiring me, which I have never try it before.
Yet, I cannot follow point 5.
How can I insert humidistat in "ZoneHVAC:IdealLoadsAirSystem" object?
Do you mean I shall input the humidity ratio by self-calculation ?
Anyway, I have learnt from you ~ many thanks !! :)
