Posch et al (2017) presented a 3D-elastohydrodynamic (EHD) simulation model of a reciprocating compressor that models journal bearings and piston dynamics for analyzing mechanical losses. These 3D simulations were helpful for detailed analysis, but they required a lot of time for the calculation.…”

This paper describes a new approach to improve compressor efficiency by using 1D CAE and 3D CAE. First, a 1D simulation model of a reciprocating compressor is proposed and the compressor efficiency is analyzed. Then, heat flow in the compressor is analyzed using a 1D thermal network simulation model and the heat receiving process of the refrigerant gas is investigated. Next, gas flow in the compressor is evaluated using 3D CFD and an improved compressor with a new structure is proposed. Finally, the effect of the improved compressor is evaluated through experiments. Results demonstrated that the proposed approach is very effective in actual development.

The article is devoted to the measurement of leakage in the recirculation path of a hermetic pump. The field of application of hermetic pumps is described. The mathematical model used in computer simulation and the mesh conditions are given. The results of the numerical modeling and the theoretical calculation are presented. The graph of the dependence of the leakage in the recirculation path on the pump head is shown. The scalar scenes of velocities and pressures in the c path are given.
