HFC-134a now is internationally recognized as one of the main refrigerant working substances to substitute CFC-12. It does not contain the chlorine atom, give no bad effects against ozonosphere and have excellent safety performances, such as non-inflammability, non-explosive ability, non-toxicity, non-pungency, and non-corrosive ability. And it is a colorless gas under ordinary temperatures and a colorless & transparent liquid under the pressure of itself. As the substitute for CFC-12, it is often used in the refrigerating systems of auto air conditioners, commercial and industrial purposes, and as the vesicant, it is used to produce the heat-protective material made of rigid plastics, and also to prepare other mixed refrigerants, such as R404A & R407C.
HFC-134a automobiles air-conditioner system are obviously superior to CFC-12 in unit refrigerantion quality and COP, It's exxhaust temperature tatio is slightly high than CFC-12, and it's relative slip temperature is 2, have a little effect on component part and circulatory system after revealing.
