Air conditioning is also necessary to cool the vehicle throughout the hot season. The exterior temperature might get quite hot throughout the summer and cause discomfort to the driver and passengers. Using the air conditioning to cool down the car helps to maintain a comfortable driving environment by maintaining a cool temperature inside the vehicle.
Here this read will help you to learn about a car AC unit before your car AC repair Dubai.
Major Parts of a Car AC unit
- Compressor
The compressor, as the name implies, compresses the refrigerant and turns it into a liquid. The gas heats up as it is compressed, at which point it is transferred to the condenser.
- Expansion valve
It's a component in a car air conditioning system that expands the high-pressure, low-temperature liquid refrigerant provided by the condenser to relieve pressure before transferring it to the evaporator for further processing.
- Evaporator
An evaporator is a device that resembles a heat exchanger and is found right behind the AC vent on the dashboard of a car. It absorbs heat from the passenger compartment and turns liquid refrigerant provided by the expansion valve into vapour, which cools the passenger compartment through the fan.
Its major function is to remove heat from your vehicle's interior. Dehumidification is a supplementary benefit. The moisture in the air condenses on the surface of the cooled evaporator coil when warmer air passes through the aluminium fins.
- Condenser
It's a device that looks like a small radiator that's used after the compressor to provide condensing, or lowering the temperature, of the high-pressure, high-temperature liquid refrigerant sent by the compressor via forced convection provided by a radiator fan or a separate fan used with the condenser. Hot compressed gases are cooled as they pass through the top of the condenser. As the gas cools, it condenses and emerges as a high-pressure liquid at the bottom of the condenser.
- Refrigerant
The refrigerant gas Freon or R135A is pumped into the air conditioning system. The capacity of refrigerant to modify its physical properties during compression is critical to the operation of an air conditioning system
- Thermal Expansion Valve or Orifice Tube
Most GM and Ford models have an orifice tube, which is probably the most prevalent. It can be found in the evaporator's intake tube or in the liquid line, midway between the condenser's outlet and the evaporator's inlet. In a well operating system, this point can be located by pinpointing the area between the condenser's output and the evaporator's inlet where the temperature abruptly changes from hot to cold.
- Receiver - Dryer or Accumulator
The model of your vehicle determines whether you have a receiver/dryer or an accumulator. In vehicles with a thermal expansion valve, a receiver/dryer is installed. In cars with an orifice tube, on the other hand, an accumulator is used.
The receiver/dryer is used to extract liquid from the gas. If any liquid gets into the compressor, it can cause it to fail. This is because a compressor is only meant to handle gases, not liquids. A desiccant is also used in this section to remove moisture. Desiccants are similar to the little, bead-filled packets included in new electronics packaging. Finally, there are filters that keep impurities out of the A/C system.
The accumulator is in charge of managing and monitoring the amount of refrigerant that enters the evaporator. It also eliminates moisture, filters debris, and stores extra refrigerant.

- Pressure Regulating Devices
Controlling the refrigerant pressure and flow into the evaporator allows you to control the evaporator temperature
Importance of Air Conditioning in a Car
One of the most crucial parts of an automobile is the air conditioning and heating system. When driving, it provides a comfortable environment for both the driver and the passengers. It's designed to warm up a car's interior during the winter and give cool air conditioning during the summer. It is critical to have a working air conditioning and heating system since it provides a safe driving environment. The car glass and windows might fog up during the winter season or in cold weather, making driving difficult. By defogging/demisting the windscreen and windows, the vehicle's air conditioning and heating system can assist in removing the fog. Using the defogging vent or turning on the car air conditioning to a low temperature first and then increasing it are two simple ways to defog the vehicle. Some automobiles include a defogging/demisting button that makes it easier to clear the fog inside the vehicle. The car must be defogged and the windscreen and windows checked before driving to ensure that it is safe to drive. It is critical to ensure that the windscreen and windows are clear because cars fog up in the winter, making it difficult to see the road. It is easier and safer for the motorist to be on the road when a driver has a clear view of the road.
