Annotation:

It is offered a graph-analytic method of determination of thermodynamic parameters and calculation of processes of hygrothermal treatment of mine air in mine conditioners under variable barometric pressure. The method is based on the exception of triple dependences of separate variables by means of input of additional functions having perfect relationships only with two independent variables. This enables to provide a visual graphic image of all basic thermodynamic processes in moist air under variable barometric pressure.
