Why Regular Gas Top Up In Your Aircon Important

In summer, with the hot weather, it is beneficial to you and allows you to stay cool in your car or house. And in winter, it will enable you to demist your windshield faster. This is obviously air conditioning. When the coolant reservoirs are not in the required levels, then such issues come up. This is when a gas top up is important.

How Does Your Aircon Work?

If you understand the aircon system operation, you will then understand the process of all the other cooling systems (indoor air conditioning, refrigerator, etc.).The overall operation of air conditioning is based on the compression of refrigerant gas. 

The system is made up of different elements: a compressor, a condenser, a pressure reducer. It will compress this gas, which will rise to high pressure (therefore at high temperature) to be then cooled to the maximum. It is this loop that will allow cold air to be blown into the passenger compartment.

But what are the actual stages of circulation of this refrigerant gas?

First, the gas increases in pressure thanks to an air conditioning compressor. This compressor is driven by the accessory belt, itself connected to the motor.

Once running, the air conditioning compressor will require more effort from the engine, driving a new part. As you will have understood, it is indeed this compressor which is at the origin of the small downsides of air conditioning, loss of power, overconsumption of fuel, etc.

The gas, now under pressure, is at a very high temperature. It will have to cool down if we want to obtain the freezing effect of air conditioning.

How Is The Air Cooled

The hot gas under pressure passes into the condenser (cooling radiator fitted with a fan) in the second step. The cooling phase then begins. The hot or cold reaction naturally liquefies the gas, thus changing from a gaseous to a liquid state.

In the second step, the gas is now liquid with an average temperature (relatively warm than cold). The dehydrator filters and cleans this liquid (5 in the diagram) to remove all the fine particles that have appeared during the process and moisture traces. This step is essential to avoid damaging the rest of the circuit.

In the third step, the lukewarm liquid will be cooled significantly. How? ‘Or’ What? The regulator expands the liquid gas (8 on the diagram). The regulator will simply depressurize the gas, which will drastically lower its temperature. The liquid which comes out of the regulator is then freezing.

In the last step, transformation of the ambient air with cold air right up to the passenger compartment takes place. The evaporator is the previous element in the air conditioning circuit. It plays the role of “air cooler”.

Conclusion

Simultaneously, the evaporator will absorb the last traces of humidity and dust in the air (thanks to the cabin filter) to transmit the healthiest possible air in the car. The moisture retained by the evaporator is expelled in the form of water. Therefore, it is quite normal to find traces of water under the car when the air conditioning is on.
