OK, those are the fundamental concepts. But how are they employed to force your vehicle to deflate and blow cool air? The concepts of evaporation and condensation are used in your vehicle’s A/C system by a series of elements that are linked by pipes and hoses. There are six major parts: the compressor, condenser, receiver-drier, thermostatic expansion valve, the evaporator and the principal component of the A/C mechanism, the refrigerant.
Refrigerant is a fluid substance able of evaporate at a low temperature. Some time ago, R-12 refrigerant was utilized in vehicles. But this chlorofluorocarbon (CFC) is damaging to the earth's ozone layer. As a result, all automobiles built after 1996 utilize R-134A, a more ozone friendly refrigerant.
Now let’s find out how air conditioning devices and its parts function.
1. The compressor is the energy component of the A/C mechanism. It is energized by a drive belt attached to the motor's crankshaft. When the A/C mechanism is switched on, the compressor drains out refrigerant vapor under high pressure and high temperature to the condenser.
2. The condenser is a piece of equipment utilized to turn the high-pressure refrigerant vapor to a fluid substance. It is risen forward of the motor's radiator, and it seems to be a radiator with its corresponding tubing and minuscule cooling fins. If you glance through the grate of a vehicle and notice what you guess is a radiator, it is almost certainly the condenser. As the car drives, air streaming through the condenser takes away warmth from the refrigerant, turning it to a fluid substance.
3. Refrigerant is transmitted to the receiver-drier. This is the depository container for the fluid refrigerant. It also takes away humidity from the refrigerant. Humidity in the mechanism may freeze and afterwards operate in the same way as cholesterol in the human blood vein, leading to thrombosis.
4. As the compressor carries on to press the mechanism, fluid refrigerant under high pressure is flowed from the receiver-drier to the thermostatic expansion valve. The valve eliminates pressure from the fluid refrigerant so that it is able to get bigger and turn into refrigerant vapor in the evaporator.
5. The evaporator is almost the same to the condenser. It includes tubes and fins and is typically fixed inside the passenger compartment. As the chilly low-pressure refrigerant is discharged into the evaporator, it evaporates and absorbs heat from the air in the passenger compartment. As the heat is absorbed, chilly air will be offered for the driver and passengers of the car. A blower ventilator inside the passenger compartment facilitates to disperse the cold air.
6. The heat-loaded, low-pressure refrigerant vapor is after that taken into the compressor to trigger the next refrigeration cycle.
Now you see the procedure is rather plain. Almost every car’s A/C mechanism operates this way, although particular automobiles could range by the distinct kind of elements they have.
