[Equest-users] Fire Place

[William Lopez]

Thanks' Nick

I added 12 ending months lines to the annual schedule, it seems like is working,  not sure if I did properly  though.

Hey there,

I need to jet from work here in a short bit so here's a quick response - you may need to ask the list for further info though ;).

Well, I'm assuming you've probably defined a schedule for a single day (hour 1 to 24), then applied that to each day of a week schedule and assigned that week schedule for every day of an annual schedule.

If that's the case, you can do this as simply as definining one more day schedule:  "off."  Define a new schedule setting each hour to zero (using either on/off or fractional as you did with the other).  Assign this day schedule to each day of an "off" week schedule, then go to your annual schedule (the one you select for the process load), and add this new "week off schedule" in to define two basic periods in the year - when the fireplace is following your daily schedule, and when it is not.  You can choose any date of the year to define it as  a "winter load," again pretty much your call.

Does that make sense?

Nick,
First of all thanks for responding my question about the fire place, the problem is that I don't know how to create the schedule for this process load, the one that I created is for the whole year but I would need just for the winter time, could you please let me know how to create a schedule for this load considering that is a winter load only.
I really appreciate your help.

William

William,

Your options are gas, electric, hot-water, and process.  Here's the definition of process in the help files:

The load will not contribute a utility load. Examples of this type of load are gasoline-powered fork trucks, oxyacetelyne welders, wood stoves, and bottled gas equipment. Sum all the process loads in the space and express the total with the keyword SOURCE-POWER. The portion of the total process load that enters as a heating or cooling load is specified with the SOURCE-LATENT and SOURCE-SENSIBLE keywords.

So a wood fireplace would be a process load ;).

Nick,Jon,
It is a wood fireplace, the procedure described below is well detailed, I just have a doubt on the line 6, what  would be the source type required by the spreadsheet?
Thanks for your  time
It is greatly appreciated

Is this a wood fireplace?  If so heat output will vary based on the type of wood, moisture content, and amount of fuel in the fire box.  You'll also need to figure out where combustion air is coming from - the space or ducted from the outside.

Hey William,


1.       Pull a cutsheet on the fireplace in question to get the input btu and heating btu incident on the space at full output.  If it's not a commercial gas/electric fireplace with a cutsheet, engineering-judgement the sucker based on something roughly equivalent.

2.       Define a schedule for the fireplace that matches your definition of  "consistently used during cold weather."  Consider a fractional schedule if it's not simply ON/OFF.

3.       In detailed mode:  Internal loads tab

4.       Spreadsheet view, select "Internal Energy Sources"

5.       Find the space with the fireplace

6.       Define a new load starting with your custom schedule.  Fill the fields in as appropriate - pretty self-explanatory at this point.  Sensible ratio would be your BTU incident on the space over the gross consumption.

7.       Carry around a smug grin coz' now you're the smartest energy modeler in the room!

Rock on,

~Nick

Hi everyone,
I am modeling a cabin log that is heated by electric baseboards and a fireplace that is consistently used during cold weather.
How can I integrate the fireplace load to the model, what would be the approach?

Thanks for the help.
