| description | The presented article deals with the solution of processes in humid air involving the particular elimination of moisture contained in the air. In the case that all of the moisture in the humid air is in the gaseous state, it is a homogeneous mixture. In the case that a part of the moisture in the humid air is in the state of liquid or solid, it is a heterogeneous mixture. In the presented paper processes, where the partial elimination of moisture from humid air (either as a liquid or as a solid phase) can appear, are studied. They are the processes, where the moist air mixture becomes heterogeneous. Based on the theory of ideal mixtures the computational methods enabling determination of the thermodynamic state of the beginning of the elimination of moisture are developed. The thermodynamic properties of dry air and water are applied. Subsequently there are designed diagrams that can be used as an aid to identify interfaces of homogeneous and heterogeneous humid air. |
