Numerical modeling and research of work for air conditioning systems

The paper presents results of long-time work for the elaboration of calculation model of air-conditioning system (ACS) for aircraft Tu-204. The basic purpose of work is the numerical modeling of work of the scheme of a ACS in moist air. The model includes the hydraulic and thermal calculation of air-conditioning components by their passport performances, and also correlation of information of power balance of system components. As a result of calculations, the thermo-hydraulic parameters of air in ACS, and also the overall performance of separate aggregates and the scheme as a whole, are determined. The obtained outcomes testify to a satisfactory confidence figure of the designed model of calculation.
