How Refrigerants Work
To grasp the importance of refrigerants in your vehicle, it’s good to understand how they function. The basic principle revolves around the thermodynamic cycle of the refrigerant, which involves four stages:
1. Compression
In the compressor, the refrigerant gas is compressed, raising its temperature and pressure.
2. Condensation
The high-pressure gas then flows through the condenser, where it loses heat to the outside air and condenses into a liquid.
3. Expansion
The liquid refrigerant passes through an expansion valve, causing it to expand and cool.
4. Evaporation
Finally, the cool refrigerant flows into the evaporator inside the car, absorbing heat and cooling the air before it is blown into the cabin.
This cycle continues as long as the air conditioning is running, and a sufficient amount of refrigerant is present in the system.
Signs You Need to Add Refrigerant
Before you consider adding refrigerant to your car, it’s essential to identify whether it’s truly necessary. Here are some common signs that you might need to recharge the refrigerant:
