3 Οκτ 2024 · Air Enthalpy (kJ/kg) can be calculated using the formula: \[ \text{Air Enthalpy} = \text{Air Temperature} \times \text{Specific Heat of Air at Constant Pressure} \] Air Temperature is measured in degrees Celsius (°C).
Percent outdoor air is the % of the total volume of delivered air that is outdoor air. There is more than one way to measure %OA. One method is to use a tracer gas like SF6. This gas would be used to saturate the system at a set concentration and to record how the concentration decreases over time.

12 Φεβ 2019 · These parameters were then compared with the average monthly air enthalpy values calculated through the air enthalpy index (I), for maximum (h (Max)) and minimum (h (Min)) variable values, establishing a thermal comfort enthalpy band, and plotted together in three distinct composite graphs, one for each year of study.
Section #9-Determining the TRUE % of OSA Using Charts and Formulas. • The TRUE percent (%) of outside air entering into the building via the air handling unit is found by using percentage charts or formulas. The next couple of slides will demonstrate both. OA Percentage Chart.
