Heat removed from storage rooms with cooled air.
When outside air is cooled down to storage room conditions - heat must be removed from the air.
The heat removed from the air for outside temperatures in the range 85 - 100 oF is indicated below:
- 1 Btu (British thermal unit) = 1,055.06 J
- 1 ft3 = 0.02832 m3
Example - Outside air 95 oF and storage room temperature 50 oF
From the diagram above aprox. 1.5 Btu/cubic feet must be removed from the air flow.
