Summary

In this paper, an on-line discharge capacity detection method for linear compressor is presented so that the capacity regulation control system of linear compressor can adjust its output upon the real working conditions. A mechatronic parameter, the vertical component of motional electromotive force, is applied as the character for discharge capacity detection. According to the variation tendency of this parameter, the pumping point and the top dead center (TDC) of the piston can be detected on-line. Then the discharge capacity of the linear compressor can be gained by comparing the relationship between the piston stroke, the pumping point and TDC. An experimental bench, as well as a simulation model is setup to verify the feasibility of this method. The investigation results show that the simulation prediction fit well with the experimental results. The discharge capacity of linear compressor under different working conditions can be detected and modulated in real time.
