Heating Room Calculation
Heating Room Calculation
(OP)
hi guys,
looking for some help double checking my calculation.
i want to heat a room in the Plant to 130F (sterilization process). The temp of surrounding rooms is 70F. If my room dimensions are LxWxH = 178'x69'x20', the cubic volume of my room is 245,640.
Delta T=60F
We know 1 BTU is sufficient to heat 55cu.ft of air by 1F.
I've calculated 21.8 BTU/sq.ft is required. However, I'm not sure how to calculate the BTU/HR required (I calculated a really large value that seems ridiculous) so that I can spec out & purchase the appropriate electrical heaters to accomplish the job.
Any help is appreciated...

And, don't forget that as you heat it up, there will be thermal losses to the surroundings that the heater must also supply.

within a couple hours would be ideal.
RE: Heating Room Calculation
The heat loss thru the structure will be in BTU/HR; Heat requirement for infiltration can be done by knowing some constants or by estimating the mass flow rate of the air and the result will be in BTU/HR; the heat requirement to sterilize will require a time element to determine the rate of temperature rise in the items in order to get BTU/HR during the batching process and for continuous process mass rate of the items to be sterilized will be required for a BTU/HR determination.
RE: Heating Room Calculation
I understand the info you're requesting, but don't have all of it. Can't I simplify this down and just make some assumptions? I found a site online Heater Shop that provides a BTU calculator.....It's calculating 4,605,750 BTU/HR based on the information I originally stated. That's seems HUGE! Then again, the volume of the room is quite large!.......
