AIR CONDITIONING AUTO PARTS: EVAPORATOR AIR CONDITIONING
Evaporator is a part of the air conditioner where the cooling liquid is evaporated. In the evaporation process air is considerably cooled. In the process of heat exchange the coolant also heats up. Therefore, the coolant must then be cooled down again via the compressor and the condenser. After the flow, cooling liquid passes back into the evaporator. If you have found small pools under the vehicle, the reason is evaporator that overheats because of deactivated conditioner. This results in sweating. If the coolant leaks, there is a leakage.If the evaporator malfunctions, air can not be properly cooled. If the air conditioner doesn’t provide set temperature or operates very slow, the problem is in evaporator leakage. Before dismantling, it is necessary to pour the coolant. As during the cooling circuit there is a pressure of several bars, the coolant can spit. After you pour off the coolant, you can replace the evaporator. However, the evaporator is often installed in hard to reach places, such as behind the dashboard.Replacement of the evaporator should be done in a specialized repair shop, as the cost is rather high and a special filling unit to empty and fill in the air conditioner is required. In any case, it is necessary to test operating capacity and tightness before mounting the dash panel. Our online shop offers you a wide range of products. Here you can purchase camshaft, oil temperature sensor, clutch cable, cooling hoses, fuel tank, boot lid, fuel pump and many others. In our assortment there are many car parts for various car brands and models.
HOW TO DETERMINE AIR-CONDITIONER EVAPORATOR FAULTS
The external condition of the component can help to define whether it is serviceable. The fins should not be soiled, however the slight dust layer is admissible. Also it is necessary to carry out diagnostics of the drainage tube. If the evaporator functions correctly, about one liter of condensed water has to be released per hour at the favorable weather.
The drainage system has the small thickness (only 1.5-2 mm) therefore it often gets clogged. The system should be checked especially thoroughly in case if the air filter is damaged.
Besides, it is necessary to measure the temperature of the air that goes out of the component. It has to be 8–12 ° C. At such values the temperature of the coolant fluctuates in the range of 0-5 ° C.
Pathogenic microorganisms can grow on the evaporator fins. It is one of the most dangerous problems which can arise during the component operation. If there is an unpleasant smell or other signs of malfunctions in the passenger compartment, take preventive measures immediately: clean the evaporator and the other elements of the air conditioning system and treat them with chemical agents.
The evaporator is operated for five years on average. Incorrect operation of the air filter and inappropriate weather conditions can reduce this term considerably.
