Sensible Heat Ratio - SHR

Sensible Heat Ratio - SHR - is defined as the sensible heat or cooling load divided by the total heat or cooling load

The Sensible Heat Ratio - SHR - express the ratio between the sensible heat load and the total heat load and can be expressed as:

SHR = qs / qt         (1)

where

SHR = sensible heat ratio (ratio of sensible heat load to total heat load)

qs = sensible heat (kW, Btu/hr)

qt = total heat - sensible heat and latent heat (kW, Btu/hr)

(1) can be modified to:

SHR = cp (to - ti) / (ho - hi)         (2)

where

cp = specific heat capacity of air (kJ/kgoC, Btu/lboF)

to = outlet temperature (oC, oF)

ti = inlet temperature (oC, oF)

ho = outlet enthalpy (kJ/kg, Btu/lb)

hi = inlet enthalpy (kJ/kg, Btu/lb)
