[Equest-users] Different cooling loads with different system types

[Walson, Kristy]

Hi All,

I am working on a model where the baseline system type is Packaged Single Zone with a Fossil-Fuel Furnace (System Type 3) and the proposed system type is Chilled Water VAV with a Gas-Fired Steam Boiler.  When I take the proposed model, save as, and then just change the system type to the DX CV system, the cooling loads in the SS-D report change.  They are less when the DX CV system.  How can the loads change?  These should stay the same and the energy used to meet these loads should change.  Has anyone run into this before?
