Compresseurs rotatifs à puissance variable munis de dérivations : transfert de chaleur et caractéristiques de performance.

Heat transfer and performance characteristics of variable capacity rotary compressors using by-pass method.

Auteurs : KWON O. S., CHUNG J. T., YOUN Y.

Résumé

Performance of the instrumented compressor is tested and temperatures at various locations of the compressor are measured. Through the comparison of characteristics between full and part load operations, possibility of capacity control using a by-pass method is verified, and some issues of part load operation are clarified. Decrease of motor efficiency, suction gas heating due to the by-passed gas of high temperature, and resistance of gas flow in the by-pass line are main reasons for the decrease in performance at part load operations. Some issues allowing performance improvement during part load are presented.
