I have a question regarding the following error message:
** Severe ** UpdateZoneSizing: Heating supply air temperature (calculated) within 2C of zone temperature
** ~~~ ** ...check zone thermostat set point and design supply air temperatures
** ~~~ ** ...zone name = B001
** ~~~ ** ...design heating load = 0.00 W
** ~~~ ** ...thermostat set piont temp = 0.000 C
** ~~~ ** ...zone temperature = 17.808 C
** ~~~ ** ...supply air temperature = 18.000 C
** ~~~ ** ...temperature difference = 0.19246 C
** ~~~ ** ...calculated volume flow rate = 4390.79153 m3/s
** ~~~ ** ...calculated mass flow rate = 4964.53310 kg/s
I am using ThermostatSetpoint:SingleHeating, ThermostatSetpoint:SingleCooling, ThermostatSetpoint:DualSetpoint. I've already checked all Schedules, they are all okay. There is no value which would lead to a thermostat Setpoint of 0°C. How do I solve this problem? Or do I have to use another thermostat object?
And I've got another question regarding the following error:
** Severe ** InitConductionTransferFunctions: Found Material that is too thin and/or too highly conductive, material name = STEEl SHEET 3MM
** ~~~ ** High conductivity Material layers are not well supported for internal source constructions, material conductivity = 50.000 [W/m-K]
** ~~~ ** Material thermal diffusivity = 1.425E-005 [m2/s]
** ~~~ ** Material with this thermal diffusivity should have thickness > 0.19612 [m]
Is this a common issue with thin material? Can I just continue using this material or would this lead to bad results later on?
