In this research interest is concentrated on the microclimate parameters optimization in cabin of military transportation vehicles. The aim of it is to provide military persons with a transportation service of a high quality. Elaboration of new HVAC (heating, ventilation and air conditioning) systems has to be performed in order to provide it. Effective work of them can be provided by elaborating control systems with usage of artificial intellect methods and progressive algorithms. A special interest for investigations and further development is devoted to intelligent HVAC systems allowing more flexible regulation (control) of the system’s compressor, fan and heater operation, and, therefore, improvement of efficiency and energy saving.
