HVAC & Refrigeration
Basic
Sensible Heat Load
Heat needed to change air or water temperature without a phase change.
Formula
Variables
QHeat (J)
mMass (kg)
cSpecific heat (J/kg·°C)
\Delta TTemperature change (°C)
Example
2 kg water, c=4186, ΔT=10: Q = 83,720 J
Did You Know?
About 60% of a home's energy bill in cold climates goes to sensible heating of indoor air.
