Claims (5)
- 少なくとも冷媒と冷凍機油とを充填し、当該冷媒を圧縮する圧縮機として、圧縮機構部がアルミニウム又はマグネシウム若しくはその合金製であり、且つ高速高負荷条件での運転が生じうるベーンロータリー圧縮機を備える冷凍回路において、
当該冷媒が、その一部又は全部として不飽和フッ化炭化水素冷媒を含有し、
当該冷凍機油が、ポリオキシアルキレン構造を有するエーテル系潤滑油と、炭素原子数が8〜25である長鎖エポキシアルカンとを含有することを特徴とする冷凍回路。 - 前記長鎖エポキシアルカンは、前記エーテル系潤滑油の充填量に対し、0.5重量%〜15重量%充填されることを特徴とする請求項1に記載の冷凍回路。
- 前記長鎖エポキシアルカンは、前記冷媒の充填量に対し、0.1重量%〜3重量%充填されることを特徴とする請求項1又は請求項2に記載の冷凍回路。
- 前記不飽和フッ化炭化水素冷媒が、分子末端にCH2=CH−又はCH2=CF−の基を有する不飽和フッ化炭化水素冷媒である請求項1〜請求項3のいずれかに記載の冷凍回路。
- 前記不飽和フッ化炭化水素冷媒が、HFO1234yf及びHFO1234zeの少なくとも1種である請求項1〜請求項3のいずれかに記載の冷凍回路。
