Aerospace Instrument-Making Annotation << Back Thermodynamic analysis of the reversible cycle of an air-cooling machine in a structure aviation air conditioning system Yu.V. Djyachenko The outcomes of the complex thermodynamic analysis of the reversible cycle of an air-cooling machine in a structure of an air conditioning aviation system (ACS) are adduced. The boundary conditions of implementations determining area of existence of the cycle in the different heating environments are reviewed. The analysis of influencing of initial parameters on thermodynamic efficiency of the cycle on idealized and practical factors is executed.
