Re: [EnergyPlus_Support] HVACTemplate Packaged VAV with DX Cooling

Dear all,

According to the InputOutputReference document (pdf-page 1992 on HVAC Template Objects ) one should be able to model a Packaged variable air volume systems with direct-expansion cooling using HVAC templates objects.

However I get rror messages as you can see below in this mail. The following objects were used:

- HVACTemplate: Thermostat

- HVACTemplate:Zone:VAV

- HVACTemplate:System:PackagedVAV

- HVACTemplate:Plant:HotWaterLoop

- HVACTemplate:Plant:Boiler

Before I started to model the Packaged VAV with DX, I modeled a very simplified problem where I used simple ideal loads system using the following objects:

- HVACTemplate:thermostat

- HVACTemplate:Zone:IdealLoadsAirSystem

This model worked out well and I could get results from it. The only change I have made developing the new Packaged VAV with DX model was deleting the HVACTemplate:Zone:IdealLoadsAirSystem and introducing new HVACTemplates as shown above.

I couldn't get the answer to this problem until now. You may have solved this problem earlier or have heard about it. Please inform me how you think I can solve this!

I got the following error messages when running this simulation:
