ABSTRACT
Increasing energy efficiency is the most important energy source today. Therefore, the main success criterion of product development studies is seen as efficiency. Compressors; It is widely used in many different sectors, especially petro-chemical, electronics, automotive, food, machinery, glass, machining, textile, construction. In our daily life, compressors are among the indispensable main components in refrigerators we use at home and in transportation (bus, train, truck). To put it in a nutshell, while people need air to live, the operation of industry depends on compressed air. Compressed air requirement is provided by compressors without alternatives. According to research, approximately 10% of industrial energy consumption in Europe and Australia is used for compressed air production. However, the energy consumed for the production of compressed air in some sectors in the USA reaches up to 30% of the total energy consumed. These studies have shown that the compressors used for the production of compressed air in the industry are the main machines that cause energy consumption. Therefore, energy efficiency in compressors is one of the main criteria for the industry.
When the screw compressor development studies are examined in the literature, the main working area is to increase the efficiency of the compressor and reduce the operating costs. This study covers the parametric optimization of the components that affect the performance of an oil type screw compressor with a one-dimensional thermodynamic model, using RSO (Response Surface Optimization Technique) and Taguchi optimization techniques, which are widely preferred in the literature. Stosic et al. investigated the performance of the rotor profile tooth depth on the compressor in their study. The outer diameter of the female rotor and the distance between the rotors, which affect the rotor tooth depth, were also investigated parametrically.
