At present ecology and energy efficiency issue is one of the main problems. Heat flow generation systems take one of the first positions in the list of the greatest energy consumption systems. This is heating and cooling of the rooms, freezing chambers etc. Climatic system of the refrigerating industrial complex is considered in article. Competitiveness of heating and cooling systems based on vortex tubes compared with chillers was shown.
