It is a kind of working substance which is circulated continuously in the refrigeration system and changes its state to realize refrigeration. The common Freon refrigerants are R12, R22, R502 and R134a. R-134a is internationally recognized as the best alternative to CFC-12. HFC-134a does not contain chlorine atoms, does not damage the ozone layer and has good safety performance; its refrigeration capacity and efficiency are very close to CFC-12, so it is regarded as an excellent long-term refrigerant. The usual way is to pack them in steel cylinders.

 

 

 

(3) Hazard characteristics: in case of high heat, the internal pressure of the container will increase, and there will be the risk of cracking and explosion.
