linear compressor, dynamic vibration absorber, compact, COP, two cylinder
Nowadays the reciprocating and linear compressors are used for the refrigerators. Their pump bodies are suspended inside the pressure vessel for the better acoustic noise and vibration isolation. But this structure is bulky, expensive and has big thermal losses. To solve these problems, we developed a compact linear compressor with internal dynamic vibration absorber which is Compact, lightweight and cost effective Potentially better energy efficiency than the conventional compressors due to the less thermal losses. Have seen 63% of the theoretical efficiency from the early non-optimized prototype. Have shown improved capacity modulation characteristics compared with the conventional linear compressors. Need optimization works on mechanism and controller for the better energy efficiency and bigger capacity. Need to reduce the acoustic noise and vibration.
