Humid air enthalpy
Humid air energyHumid air enthalpy or wet bulb is the amount of energy in the air. It is expressed in kJ/kg or kcal/kg (1 kilojoule = 4.18 kilocalories).
0 is taken as the reference temperature point.
Specific enthalpy of water is the amount of heat in 1 kg of boiling water, without a change in temperature and pressure.
Sensible and latent heatAir enthalpy is the addition of sensible heat, related to air temperature, and latent heat, related to the energy of water vapour the air contains.
Measuring enthalpy and wet bulb temperature can be done with a thermo-hygrometer.
Air quality? Energy efficiency?
Reconciling the two upstream avoids the costs related to amendment works after building or refurbishment: work costs, social costs –health, absenteeism- and environmental impacts.
Exploitation mode and ways of life have a notable share in “global cost”.
