The aim of this study is to assess how the compression equipment may work to the maximum performances with minimum consumptions. A functional dynamic model was designed so that the screw compressor process may be analyzed and a strategy for modelling and optimization of the compression equipment to be further established. The paper presents a method of functional optimization for the screw compressor in the direction of decreasing the necessary compression power using the injected oil flow.

... process significantly modifies the thermodynamic parameters of the compression so that it allows using the phenomenon for the functional optimization. The results indicate that for each regime of functioning the optimum oil flow which can be injected may be found at the intersection of the two curves representing compressor power and irreversible lost power. The findings of this research lead to a significant reduction in the operating costs.
