How to fill the high-pressure end of automobile air-conditioning refrigerant The refrigerant will inevitably not decrease after the automobile air conditioner is used for a long time. The high pressure Car Refrigerant charging pipe end charging method means that the refrigerant is added to the syste... read more
What are the air conditioning refrigerants "R32" and "R410" R32, chemical name is difluoromethane, molecular formula CH2F2. Non-explosive, non-toxic, flammable, but still a safe refrigerant. R410 is a new type of refrigerant to replace R22. R410 new refrigerant is composed of two kinds of quasi-azeo... read more
Why do you need to observe the bubbles in the sight glass for refrigerant filling? This method does show that there are bubbles that indicate a lack of refrigerant, but we must understand that the pressure loss of the liquid pipe can also cause bubbles. If the pressure loss of the liquid pipe is lar... read more
Which aspects can be observed whether the refrigerant charge is appropriate Pressure gauge observation: For example, R12 refrigerant system, the engine speed is 2 000r/min, the fan speed is the highest, and the temperature is 21～32℃, the pressure on the low pressure side of the system should be 0.15... read more
Automobile air-conditioning refrigerants are also called automobile refrigerants. Automobile refrigerants are commonly called refrigerants and ice types. They are classified into environmentally friendly (134a) and non-environmental (R12 is rarely used in car models). The refrigerant used in the aut... read more
