For the first time the work has researched the impact of methods for achieving parameters of indoor climate on efficiency of cooling and ventilation systems (CVS) work; developed the mathematic model of aerodynamic parameters of CVS taking into account mixing processes; developed solutions to increase technical and economic efficiency of industrial CVS due to creating economic jet devices. The work has proposed the structural design of jet units to control the efficiency of ventilation system flow-rate. Proposed mathematical models of heat-and-mass transfer processes can be used to compute the parameters of ventilation and conditioning systems that will allow obtaining systems with high technical and economic parameters. Work results are advised to use at the enterprises of housing and public service of Ukraine, in the systems of conditioning industrial establishments, in the systems for cooling operation environment in large transport units. The work has developed the scientific foundations for using CVS including methodological base, mathematic modeling, research of impact of regularities of change of air parameters on heat exchange processes and optimization of technical and economic parameters. The paper has developed the foundations of aerodynamic computation of CVS where variation of flow and air temperature is achieved by use of jet devices and has researched its parameters. The paper has developed the methods of projecting and engineering analysis of vortex and jet devices, defined the fields of their rational use for the conditions of CVS operation. Prototype models with improved aerodynamic parameters have been produced, their work and efficiency are checked at the ventilation systems of industrial enterprises. Implementation of obtained results to the enterprises of housing and public service will allow increasing its economic efficiency, decreasing cost and 10-12% decreasing of energy consumption level.
