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 (kW, Btu/hr)
(1) can be modified to:
SHR = cp (to - ti) / (ho - hi) (2)
where
cp = specific heat capacity of air (kJ/kg.oC)
to = outlet temperature (oC)
ti = inlet temperature (oC)
ho = outlet enthalpy (kJ/kg)
hi = inlet enthalpy (kJ/kg)
