RE: [EnergyPlus_Support] Simple mechanical ventilation

["Andy Tindale" <andy@xxxxxxxxxxxxxxxxxxx>]

I cannot use the VENTILATION object for mechanical ventilation in the
DesignBuilder interface as I am trying to implement mechanical ventilation in
such a way that it can be used alongside natural ventilation (i.e. mixed mode).
If natural ventilation is implemented using VENTILATION then we have the problem
that only one VENTILATION is allowed per zone.  And if natural ventilation is
being modelled using Comis, any VENTILATION commands are ignored.  So I have
come to the conclusion that mechanical ventilation needs to be implemented using
HVAC commands.

May I ask why you do not want to use the VENTILATION object?

There is no simple HVAC component to do what you want.  The two easiest would
be a ENERGY RECOVERY VENTILATOR:STAND ALONE with the heat recovery
effectiveness set to zero, or a AIR CONDITIONER:WINDOW:CYCLING with a dx
cooling coil that is always scheduled off.
