Web22 Jul 2024 · 1- Sensible Heat Ratio. A heat load has 2 different components: sensible heat and latent heat. Reasonable heat is the boost or reduction in air-dry bulb temperature level. Latent heat is the boost or decrease in the moisture content of the air. The total cooling capacity of an ac system is the amount of the practical heat removed, and the ... WebSensible heat transfer is based on the specific heat capacity of air and water vapor. The specific heat of air is approximately 0.24 Btu/lb°F and for water vapor is 0.45 Btu/lb°F. However there is less than 1% water vapor in air by mass so the specific heat capacity is ignored in the equation below. Q S = mc p (T 2-T 1) Q S = ρc p V(T 2-T 1)

WebSensible Heat Factor (SHF) is the ratio of Sensible Heat removed (applies mainly to cooling processes) to the Total Heat removed. SHF = SH/TH. Enthalpy Deviation.
