Car air conditioning (AC) has become a necessity while driving in the summer. It not only provides a comfortable driving experience but also helps to maintain the temperature inside the car.
The AC system is composed of various components that work together to cool the air inside the car. In this article, we will explore the different components of the car AC system and the two different types of car air conditioning systems.
Components of Car AC and Their Function
The AC system in a car is composed of various components, each of which has a specific function explained below:
- Compressor – compresses the refrigerant gas and sends it to the condenser.
- Condenser – cools the refrigerant gas and converts it into a high-pressure liquid.
- Evaporator – reduces the temperature of the liquid refrigerant and converts it into a gas.
- Refrigerant – a chemical that absorbs heat from the air and cools it.
- Expansion valve – regulates the flow of refrigerant to the evaporator.
- Blower motor – pushes the cool air through the vents and into the cabin.
Types of Car Air Conditioning System
There are two types of car air conditioning systems – the expansion valve system and the fixed orifice tube system.
1. The Expansion Valve System:
The expansion valve system is the most common type of car air conditioning system. It uses an expansion valve to regulate the flow of refrigerant to the evaporator. The expansion valve ensures that the refrigerant is released at a constant rate, which helps to maintain the temperature inside the car.
Advantages of the Expansion Valve System:
- More efficient cooling performance
- More precise temperature control
- Longer lifespan of the compressor
Disadvantages of the Expansion Valve System:
- More expensive than the fixed orifice tube system.
- Requires more maintenance
2. The Fixed Orifice Tube System:
The fixed orifice tube system is a simpler type of car air conditioning system. It uses a fixed orifice tube to regulate the flow of refrigerant to the evaporator. The fixed orifice tube restricts the flow of refrigerant, which helps to maintain the temperature inside the car.
Advantages of the Fixed Orifice Tube System:
- Less expensive than the expansion valve system
- Requires less maintenance
Disadvantages of the Fixed Orifice Tube System:
- Less efficient at cooling the car.
- Less precise temperature control.
- Shorter lifespan of the compressor.
Why Should You Service Your Car AC?
It is important to service your car’s AC system regularly to ensure that it functions properly to reduce the causes of AC failure. Here are some reasons why you should service your car AC on a regular basis:
- Prevents (refrigerant) Freon leakage in the car.
- Increases the lifespan of the AC components.
- Improves the cooling efficiency of the system.
- Removes unpleasant odors from the car.
- Reduces the risk of costly repairs in the future.
Conclusion
Car air conditioning is an essential feature that provides comfort and relief during hot and humid weather. Understanding the components and functioning of the car AC system can help you choose the right type of AC for your car. Regular maintenance of the AC system can ensure that it functions properly and lasts longer.
