The air conditioning system operation of a car is identical to that of a domestic air conditioning system.
The elements of a car air conditioning
A closed circuit containing a refrigerant R 134 A. This fluid has all the qualities essential for automotive air conditioning systems: non-flammable and chemically stable, it also blends easily with lubricants ...
4 basic elements of a car air conditioning:
-Air conditioning compressor. And disengageable belt driven, it allows the circulation of fluid in the circuit part and the general operation by compressing when in gaseous phase.
-The capacitor. It is placed in front of the cooling radiator and accelerates the transfer of heat by cooling the refrigerant.
-Regulator reduces the meanwhile, the fluid pressure and regulates its flow rate in the evaporator to ensure complete conversion of the liquid gas.
-The evaporator, is a heat exchanger that will transform the liquid into gas. It removes moisture and heat to the air so cold that happen in the cockpit of the car.
4 complementary elements of a car air conditioning:
It dehydrator it absorbs residual moisture of the circuit to protect it from corrosion, the brutal pressure changes and makes a pool of fluid in the liquid phase.
The thermostat-authorize or not the operation of the compressor depending on the temperature of the evaporator.
-Continuously monitors the pressure switch high and low pressures in the liquid phase of the circuit, for controlling the fan and the electromagnetic clutch of the compressor.
-The electromagnetic clutch. Driven by the pressure switch, thermostat, and the fuel injection systems, it prevents the air conditioning compressor to run continuously.
Maintenance of a car air conditioning
Nowadays, the automotive air conditioning is common. If the car air conditioner is more robust than in the past, it does not require a less correct and regular maintenance for an air conditioning system is not maintained may soon be detrimental to the health of passengers.
-Changing the air conditioning compressor belt and each revision of the dehydrator filter every 2 years.
Control of the charge of refrigerant. If leakage occurs, an operation of discharge and charge is to be performed by a specialist.
-Replacing the cabin air filter at least every two years.
-Verification of condensations leading to the discharge line which is located under the left front fender of the car in general.
-Setting the air conditioner thermostat car.
Hunting mushrooms often proliferate in the evaporator using appropriate antifungal products.
Tips
For your car aircon works optimally, some small reflexes are to be acquired.
-Reduce opportunities of thermal shock if possible (do not let not the doors of the car wide open even though the air conditioning is running for example!).
-Operate the air conditioner regularly to allow lubrication of the joints air conditioning compressor.
-Use air conditioning throughout the year. In winter, the air conditioning allows a very rapid demisting.
