In industrial and household refrigeration systems, about a quarter of all electricity is consumed, therefore the improvement of these systems has always been and will remain an urgent task. Today, the industry faces new challenges in the area of ​​protection of the ozone layer and the limitation of greenhouse gases. The main challenge for the refrigeration industry today is the transition to organic refrigeration agents, since F-gas will be banned after four years. Research and development of such systems is the field of competence and competence of research groups (V. Dagilis, L. Vaitkus, A. Balčius). The result will be 15-30 pages. technical feasibility study to evaluate the efficiency of the compressor under investigation, the effect of technical solutions on efficiency, using numerical compressor simulations.
