Car air conditioning problems will not go out of these reasons

The presence of a car air conditioner has become one of the indispensable necessities when operating the car, especially in hot countries such as the Arab countries, where it works to cool the temperature inside the car, which adds more comfort to the driver, so it is important to know how to take care of the car air conditioner and maintain it.

What is a car air conditioner and what are its components?

The air conditioning in the car is a device that cools the temperature inside the car, which gives the driver a comfortable atmosphere, which increases his focus and leads to safer driving and reduces the rate of accidents, which is very similar to the air conditioning in the home.

Car Air Conditioner Components:-

• The compressor is powered by electricity, which pulls the refrigerant gas from the low evaporator and compresses it into a high pressure gas. It is located in front of the car machine and is managed by a single belt or a joint belt.
• A condenser in the form of a screw tube containing liquid refrigerant.

Air passes through it from the outside, THE CONDENSER, and it is installed in the front of the car in front of the radiator until the heat is expelled from the refrigerant gas and transformed into a high-pressure liquid.

• EXPANSION VALVE EXPANSION VALVE VALVE

It regulates the passage of the right amount of the refrigerant compound to the evaporator. There are two types of it:
A – Thermal expansion valve.
B- Constant flow tube

• EVAPORATOR, which is similar in shape to a condenser and consists of a spiral tube through which the coolant passes.
• A fan to draw air from the car cabin and pass it on to the evaporator.
• Refrigerant delivery valve to the gas compressor.

Here we show the most famous malfunctions of cases of lack of cooling in the car air conditioner:

1- If the cold is intermittent, meaning it increases and weakens, the reasons are:

1.  – The presence of an electrical malfunction such as a disconnection in the fuses or relays.
2.  High temperature in the radiator due to the accumulation of deposits.
3. The thermostat is faulty.
    

 2- The cold is weak, the reasons are:

1. Low gas pressure.
2.  – The air conditioner is loose.
3. The sprayer is out of order.
4. The radiator fan is out of order.
    

  3- The coolness is good with a sound or sounds outside the car. The reasons are a defect in:

1. The air conditioner is loose.
2. Roman belt drive.
3.  Compressor is down.
4. Roman Compressor.
    

4- The cold is good with an unpleasant smell, the reasons are:

• – The presence of dirt inside the freezer or the cooling room, which is known as the evaporator.
•  The presence of a dead animal or insects inside the friezes.
• The presence of water deposited under the floors.
   

5- The cold is good, but the cold air is weak. There are 3 reasons:

• The indoor fan is faulty.
• Dirty fries.
• Cold air escapes from the joints.
• The internal filter is dirty and needs to be changed or cleaned.
   

6- The cold is very weak and the air pressure is fine. The reasons are:

• The compressor is not working.
• The fuses are not good
• The thermostat is defective.
• The relay is not working. 
   

7- The coolness is good with a sound inside the car salon, for the reasons:

• – Something fell on the freezer fan ‌
• – Corrosion of fan pistons
• Fixing screws loose
   

8- The air conditioner does not turn off when the required coldness is reached. The reasons are:

• Insufficient or deficient Freon gas quantity.
• The thermostat is damaged and does not work.
• The compressor is weak
   

9- The compressor runs for a while and then disconnects quickly. The reasons are:

• Small amount of gas
• Excessive amount of gas
• The presence of deposits in the radiator.
• The radiator fan is not working.
   

10- The presence of water inside the car salon, the reasons are:

•  – The waste pipe is dissolved.
•  There is a crack in the freezer box
•  There is a block at the exit of Al-Fadal
