Cooling Massive Heat Loads
Now that I have taken the time to get some education on how to use the Forums I will ask this question again and explain a little better.
I need to heat and cool about 3000 lbs of glass panels (solar) cycling them between 85'C and -40.
The cycle time with dwells is between min 3 hours and max of 6 hours.
I have looked up the specific heat of glass and it is .20 so I have a factor of 5lbs per degree F per BTU. Right?
If I wanted to do 180'F per hour ramp times I would need around 110,000 BTU-Hr's of cooling (excluding the box losses etc) I know I also will need a ton of airflow as well.
Do these numbers seem right?
Thanks in advance for any help
