Effective method of the average enthalpies' difference calculating in the contact-surface heat exchange apparatuses is represented. It is optimal taking into account as complication as well accuracy obtained results. This method gives possibility to calculate average enthalpies' difference in contact-surface heat exchangers both ways due to chart created or analytical equation. By results of theoretical and experimental investigations the table has been composed, which proves high accuracy of calculating results.

There are presented the results of air jet's leakage condition influence research on its spread character. By results of investigations coefficient of air distribution device with specific leakage condition velocity reducing has been determined and possibility of this outlet practical using has been based. Two air distribution devices at leakage specific condition have been investigated. The aim of using of leakage specific condition is velocity reducing in air supply jets. It is important at organizing of small volume rooms ventilation. By investigation results charts have been obtained, which describe velocity reducing intensity in air jets. Results of research give possibility to utilize practically investigated air distribution devices in ventilation technique.
