100% Outdoor Air Unit No ERV
Read through several DOAS discussions pertaining to using ERV's for 100% outdoor air. I have a specific application where I need to not have ERV's just cooling and heating coils (water cooled DX) that maintain specific leaving temperature and humidity ratio requirements.
I am working on testing a few options but wanted to see if anyone has done this before and has any input? Specifically on how to setup the controls for the leaving temperature and humidity requirements.
what software are you using? Also a DOAS doesn't need to have an energy recovery wheel. Putting setpoints on the cooling and heating coils will control the coils as you require (this depends a bit on how you are modelling your system, but in general that works)
I should have included that. I am using the latest Open Studio. What I really need to figure out, more because I have never used it before, is how to set the cooling coil to control to a leaving humidity ratio and then the heating coil or hot gas reheat would bring it back up to temperature.
I'll put this in the answer as i think it is an answer rather than a comment
