Design Optimization of an Oil-Flooded Refrigeration Single Screw Compressor

A single screw compressor is usually sealed by means of its tiny clearances. The theoretical research and the practice application shown that the leakage in the working process is always the key factor influencing the performance of this kind of compressor. Besides meeting the need of lubrication, the oil injection can greatly improve the sealing effect. It is obvious that the reduction of clea...

Performance Improvement of R134a Refrigerator Compressor

It will bring about many problems for a Rl2 refrigerator compressor to use Rl34a as refrigerant directly, such as power increasing, capacity dropping, and noise rising up etc. In order to solve these problems, the mathematical model, optimization model and special test system were built up, many improvements were made by means of the calculating and the testing results. Finally, the performance...
