R507和R404A一样是用于替代R502的环保制冷剂，但是R507通常能比R404A达到更低的温度。 R507适用于中低温的新型商用制冷设备（超市冷冻冷藏柜、冷库、陈列展示柜、运输）、制冰设备、交通运输制冷设备、船用制冷设备或更新设备，适用于所有R502可正常运作的环境。

2025年2月13日 · 温度表现：r507通常能比r404a达到更低的温度，适用于更低温的制冷需求。 能耗和效率：采用相同的压缩机条件下，r507的制冷量比r22大7%-13%，而r404a则是4%-10% 。同时r507的换热性能优于r404a 。 温度范围：r507通常能够实现比r404a更低的工作温度。

2020年2月3日 · • Inform the doctor that the injured person was exposed to the refrigerant R507. Preferably, the injured person should be given an appropriate label. • Loosen the clothing around the chest in order to facilitate breathing. • Mouth-to-mouth resuscitation is to be applied if required.

2024年9月10日 · R507A制冷剂是一种不含氯的共沸混合制冷剂，由HFC-125和HFC-143a组成，常温下为无色气体，自身压力下为无色透明液体。 这种制冷剂因其环保特性和良好的制冷效果，被广泛用于替代传统的R502制冷剂。 R507A制冷剂的分子量适中，沸点较低，使得它在低温环境下表现出色，特别适用于中低温冷冻领域，如冷库、食品冷冻设备、船用制冷设备等。 其临界温度和临界压力是衡量制冷剂性能的重要指标。 R507A的临界温度较高，说明它在高温下仍能 …

Freon™ 507 refrigerant is an azeotropic mixture of R-125 and R-143a with zero ozone depletion potential (ODP). It is a safe, effective alternative to some chlorofluorocarbon (CFC) and hydrochlorofluorocarbon (HCFC) refrigerants, including R-502.
