Air-permeable areas such as openings, slots, ducts, and others are always sources of energy losses when there are temperature differences between spatially separated areas. It is therefore of interest to identify such energetic weak points. Temperature-induced flows, and consequently energy losses, can be caused or influenced by leakages.

摘要

Air-permeable areas such as openings, slots, ducts, and others are always sources of energy losses when there are temperature differences between spatially separated areas. It is therefore of interest to identify such energetic weak points. Temperature-induced flows, and consequently energy losses, can be caused or influenced by leakages.
