R448A

簡介 Introduction：

Solstice N40屬於ASHRAE 34 A1級(不可燃)製冷劑，不會消耗臭氧。其GWP值僅為1273(IPCC，AR4)，比R-404A(GWP值為3920)低65%，是理想的R-404A和R-22的低GWP值替代品，可顯著提升系統能效。此外，Solstice N40經過專門設計，幾乎能直接替代R-404A，是適合超市應用的理想解決方案。系統只需稍加調整即可完成改造，施工快且易於維護。
迄今為止，Solstice N40已被廣泛應用在全球2,000多套系統中，在歐盟、美國、日本和亞太地區獲得眾多領先系統和冷櫃設備製造商的支援。

Solstice N40 is an ASHRAE 34 A1 (non-combustible) refrigerant and does not consume ozone. Its GWP value is only 1273 (IPCC, AR4), which is 65% lower than R-404A (GWP value 3920). It is an ideal low GWP value alternative to R-404A and R-22, which can significantly improve system energy efficiency. In addition, Solstice N40 is designed to replace R-404A almost directly, making it an ideal solution for supermarket applications. The system can be retrofitted with only minor adjustments, and construction is fast and easy to maintain.
So far, Solstice N40 has been widely used in more than 2,000 systems worldwide, with support from many leading system and refrigerator equipment manufacturers in the European Union, the United States, Japan, and the Asia-Pacific region.
