Sensible Cooling load from ventilation air Solution

Follow our step by step solution on how to calculate Sensible Cooling load from ventilation air?

FIRST Step Consider the formula

Q s = 1.1 \cdot VFM \cdot TC

Next Step Substitute values of Variables

∴

Q s = 1.1 \cdot 25 \cdot 12°F

Next Step Convert Units

∴

Q s = 1.1 \cdot 25 \cdot 262.0389K

Next Step Prepare to Evaluate

∴

Q s = 1.1 \cdot 25 \cdot 262.0389

Next Step Evaluate

∴

Q s = 7206.06926202774W

Next Step Convert to Output's Unit

∴

Q s = 24604.5898837471Btu/h

LAST Step Rounding Answer

∴

Q s = 24604.5899Btu/h
