چکیده انگلیسی
This paper has constructed a bypass mechanism mathematical model in scroll-type compressor (STC) and has been integrated into a simulation package to predict the STC performance. The bypass mechanism, when added to a fixed scroll, is used to prevent over-compression and liquid slugging. Under five specified operating conditions, it was found that the STC with the bypass action increased the isentropic efficiency 2.5–10% more than the STC without the bypass action. Meanwhile, the calculated results of the developed model have been validated by a STC testing apparatus. In addition, it was found that the design of the bypass mechanism in the paper, can completely avoid over-compression and pressure discrepancy while the STC is in operation.
