Development of high-efficiency, low-vibration rotary compressor for an HFC-410A air-conditioner.

Author(s) : KAGEYAMA K., SHIKANAI T., GOTOH T., et al.

Summary

As the pressure of HFC-410A is 1.6 times higher than that of HCFC-22, the rotary compressor in conventional design has a lower efficiency due to greater leakage from the compression chamber to the suction chamber. The length and the diameter of the cylinder have been optimized to reduce the leakage and are highly reliable at the sliding surfaces between the blade and the cylinder. Rotational vibrations have been reduced by improving the control method, which generates the motor torque adjusted to the fluctuation of the gas compression torque.
