[ "How does Air Conditioningwork in VehiclesItis that time of the year again! With scorching heat and sun gazingright overhead, it can become vexatious. But fortunately, airconditioners still exist! They are our only respite during heatridden days of summer. Now, youll have no hesitation in going outin summer afternoons. It is because of the cooling system in the car.Vehiclesalso have an air conditioning system. The system doesnt producecold air. Instead, it dispels heat and moisture from the car tooutside. All air conditioners work the same way, be it in buildings,hallways or a car. The refrigerator and freezers also work in thesame way. However, there is a mechanism of cooling that is used incars.Howdoes cooling happen in your car?Thephysics behind cooling in cars is evaporation and condensation, thenexpansion and compression. There are five main components to thewhole system, namely the compressor, condenser, receiver-dryer,expansion valve, and the evaporator. The process involves a highpressure/low-pressure closed-loop system. The refrigerant changesfrom a gas to a liquid, and then back to gas.Therefrigerant used in the vehicle is in liquid form. It evaporates atlow temperature and liquefies later at high pressure. Earlier R12 therefrigerant was used a lot in cars. But it was found to be a reasonbehind ozone depletion as it contains CFCs. Now all cars use arefrigerant called R132A which is a non-CFC liquid. Let us now diveinto the mechanism of thermodynamics that operates here:Compressor:The refrigerant in the vapourstate passes through the compressor. The compressor is the workstation of the air conditioning system. It pumps refrigerant vapourat high pressure to the condenser.Condenser:The condenser is used to change the high-pressure refrigerant vapourto a liquid. It looks very similar to a radiator. The vapouris condensed to a liquid because of the high pressure that isdriving it in.Receiver:The receiver/dryer is like a reservoir for the liquidrefrigerant. It removes any moisture that remains in the liquidrefrigerant. Moisture in the system causes havoc, with ice crystalscausing blockages and mechanical damage.Expansionvalve:The refrigerant under high pressure flows from the receiver-drier tothe expansion valve. The valve removes pressure from the liquidrefrigerant so that it can expand and become refrigerant vapourin the evaporator.Evaporator:Just like condensers, evaporators are also similar to radiators.They have fins and tubes like radiators. As the cold, low-pressureliquid refrigerant passes through it, vaporization occurs. Therefrigerant is converted to a gaseous form. It absorbs heat from theair in the passenger compartment, so cold air is circulated insidethe car.Thelow-pressure refrigerant gas passes through the condenser. The cyclecontinues again as the condenser converts it back into liquid form.Ifyoure facing any air conditioning issues, or are looking for cheapNexen tyres,contact us at FlaxleyTyres.Our professionals will be more than happy to help you and provide youthe best in class solutions for affordable prices." ]
