RE: [EnergyPlus_Support] Simple Heating System





 

 

************* Beginning Zone Sizing Calculations
   ** Warning ** Calculated design cooling load for zone=ZONE ONE is zero.
   **   ~~~   ** Check Sizing:Zone and ZoneControl:Thermostat inputs.

This warning is caused by not having cooling equipment used for the zone, and can be ignored.
When using the weather file for sizing, some of the outside air temperature is higher than the set point temperature.
 
The Zone mean air temperature problem may be caused by the  0,  enteries for the maximum flow rates in a number of objects.  Try changing them to autosize.

Subject: [EnergyPlus_Support] Simple Heating System

 
Hello Everyone,
I am new to EnergyPlus and I need your help!

Using OpenStudio I created a very simple single-zone building 10m x 10m x 2.85m. I used the default constructions that OpenStudio assigned to the building envelope.
I am trying to model a very basic water heating system (no infiltration, ventilation or cooling defined). The system consists of:
1) Boiler
2) Circulation pump
3) Radiators

I use the following components to model the system in EnergyPlus:
1) Boiler:HotWater
2) Pump:VariableSpeed
3) ZoneHVAC:Baseboard:Convective:Water

I set the elements to be autosized.
I created a Heatign Setpoint Schedule, where I specified that during the 5:00 - 19:00 period a temperature of 21 degrees should be maintained and also 15.6 degrees during the rest of the time.

As a result of the simulation I get this warning:
************* Beginning Zone Sizing Calculations
   ** Warning ** Calculated design cooling load for zone=ZONE ONE is zero.
   **   ~~~   ** Check Sizing:Zone and ZoneControl:Thermostat inputs.

Also the .eso file reports the Zone Mean Air Temperature, where the values reported do not match the time and the corresponding temperature as specified in the Heating Setpoint Schedule.

My questions are:
1) Is the system properly modeled using ZoneHVAC:Baseboard:Convective:Water?
2) Why am I getting this warning and what can I do about it?
3) Why the zone mean temperature values in results differ from the temperatures set in the schedule?

Thank you very much!
Lyuben Barosow
