本明細書において用語「冷媒」には、ISO817(国際標準化機構)で定められた、冷媒の種類を表すRで始まる冷媒番号(ASHRAE番号)が付された化合物が少なくとも含まれ、さらに冷媒番号が未だ付されていないとしても、それらと同等の冷媒としての特性を有するものが含まれる。冷媒は、化合物の構造の面で、「フルオロカーボン系化合物」と「非フルオロカーボン系化合物」とに大別される。「フルオロカーボン系化合物」には、クロロフルオロカーボン(CFC)、ハイドロクロロフルオロカーボン(HCFC)及びハイドロフルオロカーボン(HFC)が含まれる。「非フルオロカーボン系化合物」としては、プロパン(R290)、プロピレン(R1270)、ブタン(R600)、イソブタン(R600a)、二酸化炭素(R744)及びアンモニア(R717)等が挙げられる。
(2-1)冷媒成分
詳細は後述するが、冷媒A、冷媒B、冷媒C、冷媒D、冷媒Eの各種冷媒のいずれか1種を冷媒として用いることができる。
本開示の冷媒は、冷凍機における作動流体として好ましく使用することができる。
本開示の冷媒組成物は、本開示の冷媒を少なくとも含み、本開示の冷媒と同じ用途のために使用することができる。また、本開示の冷媒組成物は、さらに少なくとも冷凍機油と混合することにより冷凍機用作動流体を得るために用いることができる。
本開示の冷媒組成物は微量の水を含んでもよい。冷媒組成物における含水割合は、冷媒全体に対して、0.1質量%以下とすることが好ましい。冷媒組成物が微量の水分を含むことにより、冷媒中に含まれ得る不飽和のフルオロカーボン系化合物の分子内二重結合が安定化され、また、不飽和のフルオロカーボン系化合物の酸化も起こりにくくなるため、冷媒組成物の安定性が向上する。
トレーサーは、本開示の冷媒組成物が希釈、汚染、その他何らかの変更があった場合、その変更を追跡できるように検出可能な濃度で本開示の冷媒組成物に添加される。

図16は、本開示の一実施形態に係る空調機1の構成図である。図16において、空調機1は、利用ユニット2と熱源ユニット3とによって構成されている。
空調機1は、圧縮機100、四路切換弁16,熱源側熱交換器17、減圧機構としての膨張弁18、及び利用側熱交換器13が、冷媒配管によって環状に接続された冷媒回路11を有している。
冷媒回路11のうち、利用側熱交換器13は利用ユニット2に属している。また、利用ユニット2には、利用側ファン14が搭載されている。利用側ファン14は、利用側熱交換器13への空気の流れを生成する。
冷媒回路11のうちの圧縮機100、四路切換弁16,熱源側熱交換器17、及び膨張弁18は熱源ユニット3に属している。また、熱源ユニット3には、熱源側ファン19が搭載されている。熱源側ファン19は、熱源側熱交換器17への空気の流れを生成する。
図17は、圧縮機100のモータ70の運転回路図である。図17において、接続部30は、交流電源90から圧縮機100のモータ70へと周波数変換をさせずに電力を供給させる回路である。
上記のように構成された圧縮機100の運転回路において、交流電源90が投入されると、補助巻線728に正特性サーミスタ21を通じて電流が流れ、モータ70が起動する。
(6-4-1)
少なくとも1,2-ジフルオロエチレンを含む混合冷媒を使用した空調機1において、交流電源90とモータ70との間に電力変換装置を介在させずに圧縮機100を駆動することができるので、比較的安価な構成で、環境保護に配慮した空調機1を提供することができる。
少なくとも1,2-ジフルオロエチレンを含む混合冷媒を使用した空調機1において、正特性サーミスタ21と運転コンデンサ22との並列回路である起動回路20を補助巻線728に接続したことによって、圧縮機100のモータ70の起動トルクを大きくとることができる。
モータ70が誘導モータであり、比較的低コストで高出力が可能であるので、空調機1の高効率化が可能である。
図18は、変形例に係る空調機1における圧縮機200のモータ170の運転回路図である。図18において、モータ170は、三相誘導モータであって、接続部130を介して三相交流電源190に接続されている。
(6-6-1)
少なくとも1,2-ジフルオロエチレンを含む混合冷媒を使用した空調機1において、三相交流電源190とモータ170との間に電力変換装置を介在させずに圧縮機200を駆動することができるので、比較的安価な構成で、環境保護に配慮した空調機1を提供することができる。
モータ170が誘導モータであり、比較的低コストで高出力が可能であるので、空調機1の高効率化が可能である。
