Provided is a refrigerant-containing composition which has the characteristics of having a coefficient of refrigeration (COP) and refrigeration capacity equal to or higher than R404A, and having a sufficiently low GWP. Specifically, the present invention provides a composition containing a refrigerant, the refrigerant containing trans-1, 2-difluoroethylene (HFO-1132 (E)) and 2, 3, 3, 3-tetrafluoropropene (HFO-1234yf), the content ratio of the HFO-1132 (E) being 35.0-65.0 mass% and the content ratio of the HFO-1234yf being 65.0-35.0 mass% with respect to the total mass of the HFO-1132 (E) and the HFO-1234yf, and the refrigerant being used for operating a refrigeration cycle having an evaporation temperature of-75 DEG C to-5 DEG C.
本发明提供一种含有制冷剂的组合物,其具有具备R404A同等或以上的制冷性能系数(COP)和冷冻能力、并且GWP足够小的特性。具体而言,本发明提供一种含有制冷剂的组合物,该制冷剂含有反式‑1,2‑二氟乙烯(HFO‑1132(E))和2,3,3,3‑四氟丙烯(HFO‑1234yf),相对于HFO‑1132(E)和HFO‑1234yf的总质量,HFO‑1132(E)的含有比例为35.0~65.0质量%、HFO‑1234yf的含有比例为65.0~35.0质量%,该制冷剂用于使蒸发温度为-75~-5℃的冷冻循环运转。
