Résumé

Low global warming potential refrigerants such as HFO-1234yf are attractive as alternative refrigerants in air-conditioning and cooling systems. However, larger compressor sizes were required due to the lower fluid density compared with R410A. Thus, a new wing-vane compressor which has no contact between the vane and the cylinder has been developed to prevent an increase in the size without performance degradation. The rotary motion of the vane is supported by the partial arc vane guide on the upper and lower ends of the vane. Discovering the lubrication properties of the vane guide was one of the issues required in development. So we analyzed the friction coefficient between the vane guide and the guide bearing with numerical analysis, and measured the friction coefficient by experiment. We confirmed that the friction coefficient of the analysis and experiment result are in good agreement, and can be organized in a Stribeck curve as well as full journal bearing in the fluid lubrication region.
