Summary

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 R410A. 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. The wing-vane type has higher compression efficiency compared to the conventional sliding-vane type as it has no friction loss on the vane tip and it can significantly reduce the mechanical loss for the conventional sliding-vane type. Since the structure of the wing-vane type is different from the conventional vane type, the load characteristics on the rotor and vanes are completely different from the conventional vane type. Therefore, 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) Characteristics of torque and load are equivalent to those of the conventional vane type. (2) Lubrication of the newly added partial arc guide bearings is important to ensure reliability.
