How does a Car AC work?

Switching on the air conditioner is the first thing you will do after getting into your car after a long tiring day. Don’t you? The moment a cool breeze touches your face, the entire tiredness and exhaustion vanish within a second and make you feel refreshed once again. Needless to say, we all rely on air conditioners during summers as it saves us from the exotic heat and keeps us comfortable all day. Have you ever wondered how this tiny window fixed in your car dashboard works and why we should consider the best mechanics in Adelaide for its service or repair?

A car air conditioner is a complex group of machinery in which many parts are interconnected and have a role to play. The refrigerant system in the car air conditioner converts gas into a liquid and then converts it into a gas again and again. Post completion of this cycle, it gets converted into a cold gaseous state in the evaporator that at the end gets blown out in the cabin.

What are the components of a Car AC system?

The components used in car AC are-

  1. Compressor

The compressor is referred to as the heart and central component of the AC system.  It provides pressure to the refrigerant to convert the vapor into the liquid refrigerant and provides a refrigerant flow through the condenser.

2. Condenser

It appears like a small radiator and is utilized for lowering the temperature of high-temperature liquid refrigerant by the radiator fan.

  1. Expansion valve

Expansion Valve is used in car air conditioning systems for expanding the high pressure, low-temperature liquid by the condenser to release the pressure before sending it to the evaporator.

  1. Evaporator

It appears like a heat exchanger and is situated behind an AC vent over a dashboard of a car.  It takes heat and converts the liquid refrigerant into vapor to provide cooling in the cabin.

  1. Receiver-Dryer

It is used between evaporator and compressor for converting the liquid into vapors before sending it to the compressor for further compression.

Why does my auto A/C SUDDENLY blow hot air?

There are mainly four reasons responsible for blowing hot air.

  1. REFRIGERANT LEAK – Refrigerant leakage happens when the reservoir is depleted due to which, the air conditioner loses its cooling power and blows hot air.
  2. FAULTY CONDENSER – Since the condenser is out, it is subject to getting blocked by trees and shrubs that block the air. Due to less airflow, the air conditioner starts blowing hot air.
  3. BROKEN COMPRESSOR – The compressor is responsible for compressing the Freon that cools the cooling coils.  When the compressor gets broken, the cooling coils will get warm and cause blowing hot air.
  4. PROBLEMS WITH THE ELECTRICAL SYSTEM – Electrical system issues cause blown fuse, causing hot air blowing from the air conditioner.

Why should you service your car AC from an expert car mechanic?
