<用語の定義>
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。

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、本開示の冷媒に加え、さらに少なくとも一種のその他の成分を含有する。本開示の冷媒組成物は、必要に応じて、以下のその他の成分のうち少なくとも一種を含有していてもよい。上述の通り、本開示の冷媒組成物を、冷凍機における作動流体として使用するに際しては、通常、少なくとも冷凍機油と混合して用いられる。したがって、本開示の冷媒組成物は、好ましくは冷凍機油を実質的に含まない。具体的には、本開示の冷媒組成物は、冷媒組成物全体に対する冷凍機油の含有量が好ましくは0~1質量%であり、より好ましくは0~0.1質量%である。
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。

R410A(R32=50%/R125=50%)及び上記混合冷媒のGWPは、IPCC(Intergovernmental Panel on Climate Change)第4次報告書の値に基づいて評価した。HFO-1132(E)のGWPは記載がないが、HFO-1132a(GWP=1以下)、HFO-1123(GWP=0.3,特許文献1に記載)から、そのGWPを1と想定した。R410A及び上記混合冷媒の冷凍能力は、National Institute of Science and Technology(NIST)Reference Fluid Thermodynamic and Transport Properties Database(Refprop 9.0)を使い、下記条件で混合冷媒の冷凍サイクル理論計算を実施することにより求めた。
蒸発温度:5℃
凝縮温度:45℃
過熱度:5K
過冷却度:5K
圧縮機効率:70%
これらの値を、各混合冷媒についてのGWPと合わせて表1に示す。なお、比COP及び比冷凍能力については、R410Aに対する割合を示す。
COP =(冷凍能力又は暖房能力)/消費電力量
