Based on theoretical and experimental tests it was determined, that thermodynamic balance condition in the working space of contacting units of ventilation and air conditioning systems (HVAC systems) is entirely defined as the same values of humidity potential of finite parameters of air and water – _ = const. This makes it possible to put forward a new method of the analysis and calculation of heat and moisture exchange in contacting units HVAC systems. It was established, that condition _ = const of finite parameters of contacting environments is an index of the optimal mode of operation of the contacting unit, where in high thermodynamic efficiency of processes of heat and moisture exchange in it’s working space is achieved. The data received made it possible to work out a new approach to the implementation of energy-efficient processes in the contact units, and a new method of control their parameters. The features of the progress of processes of heat and moisture exchange in contacting units are considered viewed in the article, and also the results of the offered method of moisture content of incoming air regulation in use are presented.

Keywords: humidity potential; heat and moisture exchange; contacting units.
