Overview:Enthalpy
(kiloJoules/kg)
.
A quantity of heat per unit of mass, a SNVT_enthalpy network variable may be used to communicate enthalpy values in air conditioning and other process applications.
EXAMPLES
The enthalpy of the outdoor air is transmitted by an enthalpy sensor as 54 kJ/kg. An air-handling unit, with an economizer controller, transmits the difference in enthalpy between indoor and outdoor air as –17 kJ/kg.
