RE: [EnergyPlus_Support] AC adding





In my previous reply, I have shown you how a HVACtemplate object looks like.
 
After running this IDF, you will find another file with expansion  .expIDF.  This latter file is actually used for simulation.  You can change the extension to IDF, and it will run directly from EPlaunch.  The error messages are generated from running the expIDF.  That may be the reason why you do not see the line mentioned in the error message in the original .IDF fiie.
 
The template will generate some of the compact schedules for you.  The following is an example of some of them in the  .expIDF.


 
ScheduleTypeLimits,
  HVACTemplate Any Number;                                 !- Name
 
ThermostatSetpoint:DualSetpoint,
  Thermostat Dual SP Control,                              !- Name
  Htg_Sch_temp,                                            !- Heating Setpoint Temperature Schedule Name
  Clg_Sch_temp;                                            !- Cooling Setpoint Temperature Schedule Name
 
Schedule:Compact,
  HVACTemplate-Always 1,                                   !- Name
  HVACTemplate Any Number,                                 !- Schedule Type Limits Name
  Through: 12/31,                                          !- Field 1
  For: AllDays,                          ThermostatSetpoint:SingleCooling, !- Control 1 Object Type
CoolingSetPoint,         !- Control 1 Name
ThermostatSetpoint:SingleHeating, !- Control 2 Object Type
HeatingSetpoint, !- Control 2 Name
ThermostatSetpoint:DualSetpoint, !- Control 3 Object Type
DualSetPoint; !- Control 3 Name
!- ==========================
The above is the full expansion.
 
ZoneControl:Thermostat,
    SPACE1-1 Control, !- Name
    SPACE1-1, !- Zone or ZoneList Name
HVACTemplate-Always 2, !- Control Type Schedule Name
ThermostatSetpoint:SingleCooling, !- Control 1 Object Type
CoolingSetPoint;         !- Control 1 Name

!- =========================
Schedule:Compact,HVACTemplate-Always is the same Schedule:Compact,HVACEemplate-Always 4 with the number 4 changed to 2.
 
You may not need to make all these changes.  If you delete the heating in the original IDF, the expIDF may have the schedules changed for you.
 
Remember that any changes made in the expIDF will be lost if you re-run the original IDF.  If possible, the changes should be made in the original IDF with the template objects.
 
By the way, where is the Energy Research Group UBD.
 
I am from Singapore, and it is also in the tropical zone.

Subject: [EnergyPlus_Support] AC adding

 
Hello everyone ,

I am doing the simulation of existing building in tropics with 10 zones. In 5 out of 10 zones I have an Air conditioner . 

I am having trouble to understand how I can add it to the E+.( I am not an expert in HVAC). I believe that AC is a part of HVAC so therefore I should add to the HVACTemplate:Thermostat,HVACTemplate:Zone:IdealLoadsAirSystem  

Questions are : what is the right procedure of adding AC to all 5 zones and how is adding AC related with ScheduleTypeLimits Name, Schedule:Compact Name ( this is the errors that I've got while adding AC information to the  HVACTemplate:Thermostat,
HVACTemplate:Zone:IdealLoadsAirSystem )

Any help and suggestion will be highly appreciated.

Thank you.

Best regards, Veronika
