[Equest-users] Infrared Heaters

[Peter Hillermann]

Nick,

 

I don't know but check this out http://www.infraredradiant.com/ I was giving
all kinds of solutions just in case.

 

Thanks,

Bill/Peter:

 

I might be missing something, but this is the sort of equipment I think of
when someone says infrared heater:
http://www.spaceray.com/1_infrared-tube-heaters.php

 

Commonly found in auto garages and open-air outdoor venues.

 

If you're asking about how to model gas/electric radiant heaters of this
sort in eQuest - I think you've got a definite challenge.  You could play
the custom-space-heat-source-scheduling game for hours on end. but I would
first suggest trying a unit heater (gas or electric as appropriate) with a
fan kW/CFM of zero or nearly-zero - see if that works without errors.  

 

The way this equipment really works is interesting/tricky to us modelers
because it does not need to heat the space air to what we'd normally call
"comfortable" temperatures as the heat can hit your skin and warm you up
without heating the air around you.  You might account for this by modifying
the zone heating schedule (the target air temperature) to a lower figure -
though I'm not sure off the top of my head what would be an appropriate
figure - any suggestions?

Bill,

 

I just read about the infrared heater. If you are using people and equipment

to absorb heat and reradiate it, you have to rely on your schedules to tap

into that calculation.

 

I am totally guessing because I have never tried to set renewable energy to

a personal and equipment schedule. I'm sure it can be done however when you

look at heat generation from people it can vary from 450 BTU to 2500 BTU so

good luck. I would probably go to ASHRAE and look at the thermal comfort

data for process and heat generation of people and use the same numbers they

have set to those processes. Look at the equipment you are using and see

what it does. Add it all together and subtract from total energy that the

building is consuming.

 

Man that is complicated, best of luck to you my friend.

 

Thanks,

Bill,

 

Do you have a chart that shows how much renewable energy the unit consumes

and then uses to create heat? What you need to do is create the item in 2

parts. Its renewable component, which might be a solar collector and then

you set up a radiant heater in the room either as baseboard or as your

system in that zone.The thing that I have noticed while modeling is there

are 2 things you are looking at.. products in your building and how they

consume energy, by amount and efficiency. The second is what are you doing

to replace the energy... renewable or are you pulling it from the grid. The

model does not care where it comes from as long as when you use the

renewable it is as efficient as you say it is. I typically use PVWatt

calculator and do manual calculations because someone taught me that. You

can also set up a collector in the utility&economics tab under photovoltaic

modules. This is where you will need the solar information on your

collector.

 

The weather file needs to be correct because this is where it is pulling

your solar radiation data from watts/meter squared or watts/feet squared.

 

Hope this helps. (Easier to do by hand)

 

Thanks,

Hello,

 

Does anyone have any experience modeling ceiling hung infrared heaters in

eQuest?

 

Thanks,
