Why is the air conditioner not replaced by plastic pipes instead of copper pipes?

Why is the air conditioner not replaced by plastic pipes instead of copper pipes?

Answer:

Quantitative fluoride: in three way valve technology export connected three-way valve, pressure gauge, fluoride, fluoride bottles or vacuum hose pump, after fluorine vacuum, after the completion of the above procedures can slowly after adding fluoride, fluoride fluoride after closed bottle valve.

The measured current: air conditioning refrigeration or operation is set to become the state high speed sealing heating under low pressure valve, in the process of opening, while observing the changes of the current side fluoride close fluoride bottle valve after the rated working current of air conditioning nameplate.

Test pressure: refrigeration or air conditioning in the same state of high-speed operation of heating under low pressure valve in the process of export side plus fluoride while observing the vacuum pressure gauge pressure condition, when the pressure in the closed bottle valve 0.49MPa fluorine pressure, according to the quantity and pressure of the surrounding environment of fluorine Leon fine-tuning accurately, and fluoride.
