Abstract
The method of analysis of changes of mechanical power of the air flow in the ventilation system
Incoming article date: 11.09.2017With the aim of obtaining objective data about the energy potential of the air flow in the ventilation system proposed to use the parameter "local mechanical power flow". The formulas describing the change of this parameter in different parts of the ventilation system. Describes the author's method of graphic representation of the processes of change of flow parameters in the coordinate axes L - Pn, allowing enough just to determine the change in local mechanical power on isothermal and non-isothermal sections of the ventilation system.
