Description
図1は上記吐出マフラ(1)の構成を示す縦断面図である。上記吐出マフラ(1)は、図1に示すように、マフラ容器(2)と流入配管(流入通路)(8)と流出配管(流出通路)(7)とを備えている。
図2は上記二段圧縮機(10)の構成を示す縦断面図である。上記二段圧縮機(10)は、図2に示すように、そのケーシング(12)内に圧縮機構(13)と電動機(14)とを収容した、いわゆる全密閉型に構成されている。又、上記二段圧縮機(10)には、上述した吐出マフラ(1)と第1吸入マフラ(20)と第2吸入マフラ(21)とが取り付けられている。
次に、上記冷凍装置について説明する。この冷凍装置は、図3に示すように、上記二段圧縮機(10)と吐出マフラ(1)と第1、第2吸入マフラ(20,21)とが接続された冷媒回路(60)を備えている。
〈吐出マフラ〉
上記二段圧縮機(10)の低段側圧縮室(32)から吐出された冷凍機油混りの冷媒ガスが、上記流入配管(8)を経てマフラ容器(2)内に流入すると、該マフラ容器(2)内で冷媒ガスが消音されつつ、冷媒ガスから一部の冷凍機油が分離する。この分離した冷凍機油はマフラ容器(2)内の下部空間(2b)に貯留し、一部の冷凍機油が分離した冷媒ガスは上記流出通路(7)を経て上記マフラ容器(2)の外側に流出する。
上記電動機(14)のシャフト(25)が回転すると、上記低段側圧縮室(32)で上記低段側ピストン(30)が偏心回転するとともに、上記高段側圧縮室(33)で上記高段側ピストン(31)が偏心回転し、上記各圧縮室(32,33)の容積が周期的に変動することにより、該各圧縮室(32,33)の冷媒を圧縮することができるようになっている。
次に、上記冷凍装置の運転動作について説明する。
本実施形態によれば、上記流出配管(7)の入口部(7c)を上記下部空間(2b)内に開口させることで、上記流出配管(7)から冷媒ガスだけでなく、下部空間(2b)に溜まった冷凍機油も流出させることができる。これにより、従来とは違い、油戻し管を用いずに上記マフラ容器(2)の外側に冷凍機油を流出させることができる。この結果、上記吐出マフラ(1)の内部に冷凍機油が溜まりにくくすることができる。又、このマフラ容器(2)から流出した冷凍機油を、上記高段側圧縮室(32)を経て二段圧縮機(10)のケーシング(12)内へ戻すことができる。
上記実施形態については、以下のような構成としてもよい。

3 上側閉塞板
4 下側閉塞板
7 流出配管(流出通路)
8 流入配管(流入通路)
10 二段圧縮機

21 第2吸入マフラ
60 冷媒回路
