The Room Sensible Heat Factor - RSHF - expresses the ratio between sensible heat load and total heat load in a room. It can be expressed as:
RSHF = Qsr / Qtr (1)
RSHF = room sensible heat factor
Qsr = sensible heat load in room (kW, Btu/hr)
Qtr = total heat load in room (kW, Btu/hr)
(1) can be modified to:
RSHF = cp (tr - ti) / (hr - hi) (2)
cp = specific heat air (kJ/kg.oC)
tr = room temperature (oC)
ti = inlet temperature (oC)
hr = room enthalpy (kJ/kg)
hi = inlet enthalpy (kJ/kg)
Example - Room Sensible Heat Factor - RSHF
The sensible heat generated within a room is 4 kW. The latent heat generated is 1.4 kW.
The Room Sensible Heat Factor can be calculated as:
RSHF = (4 kW) / ((4 kW) + (1.4 kW))

The Great Sensible Heat Factor is the ratio sensible to total heat in a cooling coil.
Equivalent heat index vs. air temperature and relative humidity - in degrees Fahrenheit and Celsius.
Heat gain from persons in air conditioned spaces - in btu/hr.
Recommended indoor relative humidity vs. outdoor relative humidity and temperature.
Latent heat is the heat when supplied to or removed from air results in a change in moisture content - the temperature of the air is not changed.
Human metabolic heat gain in air conditioned rooms.
Sensible heat is dry heat causing change in temperature but not in moisture content
