Summary

In recent years, environmental concerns and energy consumption become more important. Therefore, compressor manufacturers try to design high-efficiency reciprocating compressors. Owing to developing technology, mechanical, electrical and thermodynamic losses of hermetically sealed compressors are reduced. Nevertheless, the effects of electrical motors are significant phenomena. The thermal behavior of an electrical motor is very important for motor performance, but also has a key role for compressor components heat transfer characteristics. In this study, heat transfer between the components and the electrical motor of the hermetic reciprocating compressor were investigated theoretically and experimentally. The compressor performance, indicator diagram, motor tests and the detailed temperature measurements of electrical motor and compressor components were given. Analytical model simulations of induction motor and compressor components were performed by using commercial softwares. This part describes analytical models to predict the temperatures of motor and the other parts of hermetic reciprocating compressor. The model simulations allow determining component temperatures with different motor temperatures theoretically. In addition to this, conceptual designs, which have affected the heat transfer on the components and performance of the compressor, were also applied during the study. The results of the theoretical, analytical and experimental studies are used for investigating the network including conduction, convection and radiation forms of heat transfer inside the compressor. Generated heat transfer network helps to characterize the thermal functions of the main components which leads to the new and better compressor designs.
