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
What is the comparison between refrigerant and temperature and pressure Low pressure and high temperature refrigerant: The R410 refrigerant tube evaporation temperature is higher than 0℃, and the condensation pressure is lower than 29.41995×104Pa. This type of refrigerant is suitable for centrifugal... read more
Why do cars need to be filled with refrigerant Refrigerant is the working medium in the refrigerator, called refrigerant or refrigerating working medium. It circulates in the refrigeration system. The refrigerating penalties exchange energy with the outside through the change of its own thermal stat... read more
How to add refrigerant to small central air conditioner Disassemble the device shell First disassemble the casing of the unit. Of course, it is not necessary to disassemble all the casings. We only disassemble the parts and find the refrigerant filling port. If the filling port is on the equipment c... read more
