[Hap-users] Constant Air Flow

[Brendan Arnold]

You can specify a constant volume system under your "general" tap. Make sure if you are using chilled water select "Chilled Water Air Handling Units" under Equipment Type. Then select CAV single zone or terminal reheat (dependant on your situation) in the Air System Type.   Under the "sizing data" tap you can select "user define", then specify your supply air and ventilation CFM's.

In order to determine cost for heating and cooling water you will need to construct a building to be simulated.  Thus you will need to create a chiller and boiler plant and specify all pump requirements.  Then implement these into your building.

Subject: [Hap-users] Constant Air Flow

Is there a way to force HAP to supply a constant air flow through a "system"  (this includes specifying return air and outside air requirements) and calculate the cost of providing the cooling and heating water to the "system" and "zone" reheats?  Any explanations would be helpful.

Thanks,
