What can be used instead of r12 refrigerant
R12 refrigerant can be replaced with R134 refrigerant tube. As an alternative refrigerant to R12, R134 has many characteristics similar to R12. R134a has very low toxicity and is non-flammable in the air. The safety category is A1, which is a very safe refrigerant.
The chemical stability of R134a is very good. However, because its water solubility is higher than that of R12, it is not good for the refrigeration system. Even if there is a small amount of water, it will produce acid, carbon dioxide or carbon monoxide under the action of lubricating oil. Metal produces corrosion.
The main purpose of R12 refrigerant is to be used as a refrigerant and air-soluble insecticide propellant. It is a substance that has a strong and rapid effect on the heart. It can cause changes in the cardiovascular system of animals such as arrhythmia, ventricular tachycardia, bradycardia, atrioventricular block, acute heart failure, and blood pressure drop. There are a large number of cases of death caused by inhalation of fatal arrhythmia, collapse and cardiac arrest abroad.
