Abstract

After the exhaust of rotary cylinder compressor, the refrigerant in the clearance volume will expand during the suction process of the next cycle, resulting in loss of power consumption. The paper proposes a scheme to recover the expansion power of high pressure refrigerant in the clearance volume by setting an expansion chamber, and carries out theoretical analysis and experimental evaluation. The test results show that the larger the pressure ratio is, the more expansive power is recovered. Compressors using expansion power recovery technology can improve energy efficiency by up to 3.3%.
