Summary
The possibilities for increasing the capacity control efficiency of screw oil-filled compressors with the use of control valves are considered. Based on the mathematical description of the processes in a screw compressor, a set of differential equations for the determination of the thermodynamic parameters of refrigerant and oil at any time of the working process is obtained. As a result of the solution of the system, the design indicating diagrams of compressor without regulation, with regulation by a standard control valve and with a control valve of the optimized geometry were obtained. The best results with partial capacity were obtained with the use of the control valve with changed geometry.
