Dehumidifier only on simulation

Postby roysigalingging » Mon Feb 12, 2018 2:00 pm

Hi,

I am using Design Builder v.5.0.3. Currently in my model the AHU need a temperature setpoint manager and dehumidification setpoint manager, but actually I just want to control the humidity and I also want to calculate the energy used by just using this dehumidification. When I used water cooling and set on humidity ratio option, I can't set the humidity on the setpoint manager. Its only working if I use Multi-zone humidity maximum and put temperature setpoint manager.

I'm looking for a way to just using dehumidification (without Air conditioning).

Thank you.

I may be able to help you as I have dealt with similar issues in my model recently. However, you have to specify your problem more precisely, because I don't entirely get it. Add some images, upload the model etc. :)

Hi,

On the AHU cooling coil dialog have you select the control to 2-Humidity Ratio option?

I believe that the following Help link should provide more details about Dehumidification.
