RE: [EnergyPlus_Support] Re: HVAC template

Sorry, I am not Linda

Your template is not an EPlus template.

EPlus template application requires a set of templates, a building, location, environment, and simulation control.

Sorry that I cannot help you. EPlus is not that complex to use. Complete the Exercises in the EPlus Getting Started Document (not the third party document) before asking me any more questions.

May be other users can.

Hi Dr.Linda,

I attached th picture of plant of building ,

please see it ,

Temperature at node 1 determine that boiler will be on or off ,

When temperature node 1 greater than 80C then boiler will be off and if temperature node 1 is smaller than 80C then boiler will be on. When boiler starts working it works with maximum capacity.

Temerature at node 2 controls when pump starts to work :

If temperature at node 2 greater than 65C pump will be off and if temperature at node 2 smaller than 65C then pump will be on.

When boiler is off so radiator will be off .

and in plant of this building there is no airplant and in real building there is no thermostat setpoint and try to fix air temperature at thermostat temperature .

I want to design this plant at first .I want to determine what capacity of boiler needed to set room air temperature at 20C. if I use thermostat heating setpoit at 20c then energyplus use this temperature and try to fixed it during simulation ?

and after design it I want to simulate it , and I want to know what is the real air temperature and when boiler will off and on ?

I think I could simulate this characteristic by seting availability manager.

But I don?t undrestant exactly different between setpoint and availability manager :

If I use setpoint instead of availability manager ,energyplus uses this fixed setpoint and don?t on and off boliler with this setpoint?

Coul you please help me in simulation of this building?

thanks

Just to add that the expIDF is generated before simulation.

If the templates are not selected or entered correctly, the expIDF will be generated incorrectly and the simulation may not be sucessful.

You will need more than one template to work together to complete your simple system in Iran.

Yes,you are right.
You use the template which is easier to set up.You have to fill less fields.
When you run the simulation EnergyPlus "expand" your templates and
create the objects that are needed for your HVAC. You will not have to
define the inlet/outlet node because EnergyPlus will do itself.
You will have after the simulation a new file on your folder
"Example.expidf" which is your idf after being processed and expanded
by EnergyPlus. You can rename it to "Example_exp.idf" and you will
have the idf file with all your objects created. You will have all
your nodes too.
I hope it helps you,
Ignacio Gomis
