产品说明：双企134a新冷媒是一种新型的环保型制冷剂，化学名：四氟乙烷，分子式：CH2FCF3，具有无色、无毒、不燃、不爆、热稳定性好等特点，化学性质稳定，与CFC­—2（氟里昂）相比，其臭氧消耗指数（ODP）为0，沸点-26.15度，是一种理想的氟里昂替代品。使用方法：
1、使用前必须查气阀为合格品，严禁使用劣质气阀。
2、保证充气阀的高低压管、阀与空调机接口安装正确无误，要防止罐内压力超过1Mpa（10kfg/cm²）。
3、充气时将导气管连接好，一端接在空调机上，一端接在雪种罐上，将充气阀的顶针往下旋戳穿雪种罐的顶，使罐内雪种能外溢，然后将充气阀的顶针往上旋，使雪种罐倒立，雪种即可充入空调机。
4、本品应由取得灌注汽车空调气体操作技术资格的专业技师或都在其指导下使用，为了正确操作请参阅汽车空调机的相关说明或相关技术手册。注意：
1、请勿存放在40摄氏度以上的地方。
2、罐只接驳低压侧软管。
3、请勿将罐放在发动机和散热器上。
4、请勿用力摇晃罐子。
5、使用时请参照汽车内冷气设备的说明。R134a is also known as Tetrafluoroethane (CF3CH2F) from the family of HFC refrigerant. With the discovery of the damaging effect of CFCs and HCFCs refrigerants to the ozone layer, the HFC family of refrigerant has been widely used as their replacement.It is now being used as a replacement for R-12 CFC refrigerant in the area of centrifugal, rotary screw, scroll and reciprocating compresssors. It is safe for normal handling as it is non-toxic, non-flammable and non-corrosive. Currently it is also being widely used in the air conditioning system in newer automotive vehicles. The manufacturing industry use it in plastic foam blowing. Pharmaceuticals industry use it as a propellant.
