WebConclusion. AHUs are made of the 3 basic components which are the fan, cooling and filter. In addition, AHUs can have a mixing box, UV light, heat pipe and heat wheel depending … WebThe specific enthalpy is a measure of the total energy of a unit mass, and its units are usually kJ/kg. Specific heat capacity. The enthalpy of a fluid is a function of its temperature and pressure. The temperature dependence of the enthalpy can be found by measuring the rise in temperature caused by the flow of heat at constant pressure.
