Abstract

<p> Low global warming potential refrigerants such as HFO (hydro fluoro olefin) -1234yf are attractive as alternative working fluids in air-conditioning and cooling systems to address global warming. However, larger compressor sizes were required due to the lower fluid density compared with conventional refrigerants such as R 410A. Thus, a new wing-vane compressor which has no contact between the vane and cylinder has been developed to prevent on increase in size without performance degradation. In this paper, the compression characteristics and the load characteristics were investigated by creating a dynamic model of the wing-vane type. The results are as follows: (1) The striking feature of the wing-vane type is that there is no friction loss at the vane tip. (2) Like the conventional sliding vane type, the torque and rotor load fluctuate with the same number of peaks as the number of vanes.</p>
