In general, refrigeration and air-conditioning systems consist of mechanical components such as compressors, evaporators, and condensers. Among them, the compressor transfers the refrigerant to the condenser by making it hot and high pressure through the compression process.
The power consumed by the compressor within the cold air conditioning machine is more than 80 percent of the total power consumed by the device. Thus, improving efficiency due to reduced friction losses in compressors is a very important engineering issue. This requires accurate prediction of the dynamic behavior of compressors.
The main parts of the reciprocating compressor are the crank shaft, connecting rod and piston. The principle of the motion of the compressor is that the rotary motion of the crank shaft, which is rotated by the rotor, is converted from the crank-slider mechanism to the straight reciprocating motion of the piston at the crank shaft big end.
Each of the kinematically connected parts-crank shafts, connecting rod and piston-work together during the actuation process. Therefore, in order to interpret the exact dynamic behaviour of reciprocating compressors, it is necessary to analyze them by taking into account all the major lubrication surfaces. Accordingly, in this study, a study was conducted for the analysis of lubrication characteristics considering the dynamic characteristics of the closure of the entire reciprocating compressor. Also, in this study, we have identified the lifting phenomenon of pistons that were not identified in previous studies. In addition, dynamic behaviour considering the lubrication characteristics of all major lubrication surfaces was analyzed.
