Description
[冷媒圧縮機の構成]
まず、本実施の形態1に係る冷媒圧縮機の代表的な一例について、図1を参照して具体的に説明する。図1は、本実施の形態1に係る冷媒圧縮機100の概略断面図である。
ここで、近年では、さらなる高効率化を図るため、潤滑油103としてより粘度の低いものを使用する等の対応が行われている。本開示では、冷媒圧縮機100に用いられている潤滑油103が、前記の通り、低粘度かつ高引火点を有するものである。具体的には、潤滑油103における40℃での動粘度は0.1mm2 /s〜5.1mm2 /sの範囲内であり、かつ、潤滑油103の引火点が110℃以上である。
本開示に係る冷媒圧縮機100においては、前記の通り、密閉容器101内に低粘度かつ高引火点の潤滑油103が貯留されているとともに、密閉容器101内に収容される部材には樹脂部材が含まれる。この樹脂部材は、含まれるオリゴマー量が、当該樹脂部材の全重量の2.5重量%以下のものである。オリゴマーは、樹脂部材を構成する高分子材料に含まれる低分子成分であり、通常は、高分子材料を構成するモノマーが、相対的に少ない量で重合したものを意味する。オリゴマーの具体的な重合度の範囲については特に明確に規定されているわけではないが、代表的には、重合度が100以下のもの、あるいは、分子量が1000未満のものが挙げられる。
本実施の形態2では、前記実施の形態1で説明した冷媒圧縮機100を備える冷凍装置の一例について、図2を参照して具体的に説明する。図2は、前記実施の形態1に係る冷媒圧縮機100を備える冷凍装置200の概略構成を模式的に示している。そのため、本実施の形態2では、冷凍装置200の基本構成の概略についてのみ説明するが、冷凍装置200の具体的構成はこれに限定されないことはいうまでもない。
