Revision history [back]

Having troubles modelled some basic ACs that are in some of my centre zones. I have the following errors that occur at the beginning of my simulation.

* Warning * CalcDoe2DXCoil: Coil:Cooling:DX:SingleSpeed="CC AC 6" - Air volume flow rate per watt of rated total cooling capacity is out of range at 1.523E-005 m3/s/W. * ~~~ * Environment=RUN PERIOD 1, at Simulation time=01/01 00:00 - 00:15 * ~~~ * Expected range for VolumeFlowPerRatedTotalCapacity=[2.684E-005--6.713E-005] * ~~~ * Possible causes include inconsistent air flow rates in system components, * ~~~ * or variable air volume [VAV] system using incorrect coil type.

* Warning * CalcDoe2DXCoil: Coil:Cooling:DX:SingleSpeed "CC AC 6" - Full load outlet air dry-bulb temperature < 2C. This indicates the possibility of coil frost/freeze. Outlet temperature = -37.38 C. * ~~~ * ...Occurrence info = RUN PERIOD 1, 01/01 00:00 - 00:03 * ~~~ * ... Possible reasons for low outlet air dry-bulb temperatures are: This DX coil * ~~~ * 1) may have a low inlet air dry-bulb temperature. Inlet air temperature = 16.268 C. * ~~~ * 2) may have a low air flow rate per watt of cooling capacity. Check inputs. * ~~~ * 3) is used as part of a HX assisted cooling coil which uses a high sensible effectiveness. Check inputs.

I have auto sized the ACs and these errors still seem to be occurring. Not sure how to go about fixing them. To create the ACs I used an empty air loop and threw a fan and dx single speed cooling coil on the supply side and the zone with a VAV on the demand side. If there is something wrong with how I modelled this or if anyone has any suggestions that would be greatly appreciated.

Thanks.

Edit: Not sure if this will help determine the problem but here is a screenshot of the loop I am using for the ACs.
