Aerospace Instrument-Making Annotation << Back A reversible cycle of an air-cooling machine in a structure aviation air condition system Yu.V. Djyachenko The analysis of an air conditioning system (ACS) is executed and the functional role of an air-cooling machine (AACM) is chosen. The scheme AACM is chosen and the reversible cycle of its activity is submitted. The analytical relations for an estimation of thermodynamic efficiency of the reversible cycle by the way of idealized and practical refrigerating factors are obtained. The features of activity of the cycle in the extreme temperature conditions, general and particular cases of implementation of the cycle are reviewed. The relation for definition of temperature of inversion of a heat flow during atmospheric heat exchange is obtained.
