Car A/C repairing and a/c system service
The air heating system in the passenger compartment is not capable of providing the required temperature regime. To ensure comfortable conditions for the driver and passengers, the vehicle needs to be cooled when the ambient temperatures exceed 23°C. Air conditioning systems are employed to address this issue. The picture illustrates the scheme of the air conditioning system:

Refrigerant A/C Gas replacement in Dubai
The system fills with refrigerant, which can change from gaseous to liquid and vice versa based on temperature and pressure. Refrigerant is the gas used to fill the system. Car air conditioners previously used R12 freon, but its use reduced due to concerns about the destruction of the ozone layer caused by fluorocarbons in R12.
Modern air conditioning systems now use R134a freon (tetrafluoroethane), which is considered «environmentally friendly.» This refrigerant is a type of hydrofluorocarbon (HFC) that doesn’t contain chlorine and is less harmful. However, it is 10-15% less efficient than R12 and has a more fluid nature. Car air conditioners using R134a require higher operating pressure for effective functioning. The use of R134a has complicated air conditioning systems. It’s important to note that the old and new refrigerants are incompatible due to differences in compressor oils used with them.
