Résumé

Refrigerant carbon dioxide has suitable thermodynamics properties and small influence to the environment. In this article there are studied and analysed pressure losses through the suction filter and the valve plate on discharge side of compressor and CFD simulations of the flow through these areas are carried out. CFD simulation’s results are compared with experimental measurements of pressure losses in the suction filter and on valve plate. Experimental measurements cover different areas of working envelope of the compressor. On the basis of CFD simulations were designed geometric and structural modifications of suction filter and valve plate to analyse the changes of pressure losses in the refrigerant flow.
