What is the in filtration and ex filtration

Question

Accepted Answer

Infiltration and exfiltration are terms used in HVAC engineering to describe the movement of air into and out of a building.

Infiltration refers to the unintentional or uncontrolled flow of outdoor air into a building through cracks, gaps, or openings in the building envelope.
Exfiltration, on the other hand, is the opposite of infiltration and refers to the unintentional or uncontrolled flow of indoor air out of a building.
Both infiltration and exfiltration can have a significant impact on the energy efficiency and indoor air quality of a building.
Infiltration and exfiltration can be reduced by properly sealing and insulating the building envelope, using air barriers, and maintaining positive pressure indoors.
For example, if a building has poorly sealed windows, cold air from outside can infiltrate the building during winter, leading to increased heating costs.
Similarly, if a building has inadequate ventilation, indoor air may exfiltrate, causing negative pressure and potential indoor air quality issues.

Accepted Answer

Mass transfer and solvent transfer through line filtration and to build the exit filtration during the process.
