(耐摩耗性試験)
実コンプレッサと類似の冷媒雰囲気にできる、神鋼造機(株)製の高圧雰囲気摩擦試験機(回転ベーン材と固定ディスク材との回転しゅう動方式)を用いて、耐摩耗性試験を行った。試験条件としては、試験容器内圧力1.6MPa、油量600ml、試験温度110℃、回転数500rpm、負荷荷重80kgf、試験時間1時間とした。ベーン材としてはSKH−51、ディスク材としてはFC250を用いた。耐摩耗性の評価は、ディスク材の摩耗量が極めて少ないことから、ベーン材の摩耗深さによって行った。冷媒としては、下記混合冷媒A〜Cのそれぞれを用いた。
混合冷媒A:2,3,3,3−テトラフルオロプロペン(HFO−1234yf)とトリフルオロエチレン(HFO−1123)との混合冷媒(質量比(HFO−1234yf/HFO−1123)=80/20)
混合冷媒B:ジフルオロメタン(HFC−32)とトリフルオロエチレン(HFO−1123)との混合冷媒(質量比(HFC−32/HFO−1123)=40/60)
混合冷媒C:1,1,1,2−テトラフルオロエタン(HFC−134a)とトリフルオロエチレン(HFO−1123)との混合冷媒(質量比(HFC−134a/HFO−1123)=20/80)
(安定性試験)
安定性試験は、JIS K2211−09(オートクレーブテスト)に準拠して行った。具体的には、含有水分量を100ppmに調整した供試油80gをオートクレーブに秤取し、触媒(鉄、銅、アルミの線、いずれも外径1.6mm×長さ50mm)、及び、上記混合冷媒A〜Cのいずれか20gを封入した後、140℃に加熱し、150時間後の供試油の酸価(JIS C2101)を測定した。
