产品用途：

R407C制冷剂是一种环保型非共沸混合制冷剂，主要由R32、R125与R134a按比例混合而成，主要用于替代传统R22制冷剂。其特点包括不含氯、不破坏臭氧层、热力性能接近R22，适用于空调系统和非离心式制冷设备。 

‌‌家用/商用空调系统：R407C广泛用于家用空调、中小型商用空调（如单元式空调、户式中央空调）及多联机系统，尤其适用于对温控精度要求高的场景（如医药冷藏、实验室设备）。

‌工业制冷设备：包括工业冷柜、中央空调机组等，常搭配POE合成润滑油使用，需液态充注以确保组分稳定。 

‌汽车空调系统：部分客车空调已采用R407C制冷剂，其安全性、能效比和换热效率优势显著。 

注意事项：更换为R407C需注意系统密封性，且不可直接替代初装为R22的设备（需更换润滑油及组件）。

Product Application

R407C is an environmentally friendly zeotropic mixed refrigerant, blended proportionally with R32, R125 and R134a. It is mainly used to replace traditional R22 refrigerant. It contains no chlorine, causes no ozone depletion, and features thermal performance close to R22, suitable for air conditioning systems and non-centrifugal refrigeration equipment.

Household & Commercial Air Conditioning: Widely applied in household air conditioners, small and medium-sized commercial air conditioners (packaged air conditioners, residential central air conditioners) and multi-split systems, especially for scenarios requiring high temperature control accuracy, such as medical cold storage and laboratory equipment.

Industrial Refrigeration Equipment: Used in industrial freezers and central air conditioning units. It is generally matched with POE synthetic lubricant and requires liquid charging to ensure stable components.

Automotive Air Conditioning: Adopted in some passenger car air conditioning systems, with outstanding advantages in safety, energy efficiency ratio and heat exchange efficiency.

Notes: System tightness must be guaranteed when switching to R407C. It cannot directly replace original R22 equipment; lubricants and related components need to be replaced accordingly.
