چکیده انگلیسی
A linear compressor is widely used to drive Stirling-type cryocoolers. The acoustic power it provides directly affects the performance of a cryocooler. However, it is hard to determine the output acoustic power of a linear compressor since it is difficult to measure the phase angle between the pressure and velocity. In the study, a method is proposed to calibrate the phase angle. The acoustic power of the compressor is estimated based on the calibration. The energy distribution and efficiency of the linear compressor are also analyzed. Theoretical analyses and experiments on a linear compressor are conducted. The results show that the accuracy of the calibrated phase angle is acceptable. The total power calculated by the calibrated phase angle when compared with the measured input power exhibits a deviation of less than 10%. In large scale linear compressors where the back volume is only several times higher than the compression volume, it is not possible to ignore the loss in the back volume since it can correspond to 19% of the total input power. The estimation of the acoustic power is helpful to reveal the performance of the compressor and then design a relative high efficiency cryocooler.
