，具有清潔、低毒、不燃、制冷效果好等特點，大量用于中低溫冷凍系統(tǒng)。R-410A制冷劑物化特性：常溫常壓下， R410A 是一種不含氯的氟代烷非共沸混合制冷劑，無色氣體，貯存在鋼瓶內(nèi)是被壓縮的液化氣體。其 ODP 為 0 ，因此R410A是不破壞大氣臭氧層的環(huán)保制冷劑。主要用途：大量用于家用空調(diào)、小型商用空調(diào)、戶式中央空調(diào)等。共沸制冷劑在氣化或液化過程中，蒸汽成分與溶液成分始終保持相同；蘇州金冷制冷劑工廠</p><p style="text-indent:25px">制冷劑需具有良好的化學(xué)穩(wěn)定性。蘇州金冷制冷劑工廠</p><p
