WebSensible Heat Load and Required Air Volume Chart (pdf) Latent Heat Latent heat due to the moisture in air can be calculated in SI-units as: hl = ρ hwe q dwkg (2) where hl = latent heat (kW) ρ = density of air (1.202 kg/m3) q = …
WebIn contrast, when latent heat is removed or added, the movement on the chart would occur on the vertical lines, with dry bulb temperature constant. However, most building applications include a mixed heating and cooling process that involve both sensible and latent heat. Thus, the movement on the psychrometric chart occurs on the oblique lines ... WebThe difference in the total heat of air before and after flowing through a heating or cooling coil is a change in enthalpy. Enthalpy is expressed in Btu (British thermal unit) per pound of dry air. 4. Sensible Heat Ratio. The Sensible Heat Ratio (SHR) is the total sensible heat flow divided by the total heat flow (sensible + latent).
