- Depending on external conditions and indoor air parameters, external infiltration air may contain more or less moisture than internal air. Therefore, during infiltration, air moisture can either increase or decrease. The change in moisture content due to infiltration is calculated using the formula:
W=G*(d2-d1) - Here G is the mass of infiltration air (kg), and d1 and d2 are the moisture content of indoor and outdoor air, respectively (kg/kg air).
- Thus, the value of W can be both positive and negative.
- If backwater is created in an air-conditioned room, then infiltration and the influx of moisture and heat with it are not taken into account.
