Hello All,
I'm simulating in designbuilder V3 (detailed hvac) a building in order to fulfill leed requirements.
I am getting now following warnings:
** Warning ** Coil:Cooling:DX:SingleSpeed "CL-BS-P0 AHU UNITARY COOLING COIL DX COOLING COIL" - Air volume flow rate per watt of rated total cooling capacity is out of range at 2.283E-005 m3/s/W.
** ~~~ ** Environment=ICTA, at Simulation time=01/01 00:00 - 00:30
** ~~~ ** 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.
....and then....
** Warning ** Coil:Cooling:DX:SingleSpeed "CL-BS-P0 AHU UNITARY COOLING COIL DX COOLING COIL" - Full load outlet air dry-bulb temperature < 2C. This indicates the possibility of coil frost/freeze. Outlet temperature = -10.33 C.
These warnings refer to Baseline Systems, which I have defined using directly the DesignBuilder HVAC template ASHRAE 90.1, System No. 6, leaving everything as defined by default, including AHU airflows.
Any idea on how to solve this problem would be really appreciated,
ben
