The refrigerant then passes through the condenser coils, cooling down and converting into a high-pressure liquid while releasing heat outside. This process is called the condensation stage.

The liquid refrigerant moves through an expansion valve or orifice tube, causing a drop in pressure and temperature. This is known as the expansion stage.

Inside the evaporator coils, the refrigerant absorbs heat from the car's cabin, evaporates into a low-pressure gas, and cools the air. This is called the evaporation stage.

The refrigerant cycle repeats continuously, allowing the car air conditioning system to maintain a cooling process. The right refrigerant is essential for the system's efficiency and environmental safety.

Here are the common types of refrigerants used in cars:

R-134A is a hydrofluorocarbon (HFC) refrigerant that has been used in car air conditioning systems since the 1990s. It has a high global warming potential (GWP) and is being phased out in some countries.

R1234yf is a newer type of refrigerant that is being used in some car air conditioning systems as a replacement for R134A. It has a much lower GWP than R134A, making it more environmentally friendly.

Vehicle manufacturers use different types of aircon gas in their cars, with R134a commonly used in older vehicles and R1234yf used in newer models. Using the correct type of aircon gas is essential for optimal performance and avoiding potential damage to the air conditioning system.
