Automotive Climate Control
The main components of an automotive's climate control system are:
Refrigerant: The most common refrigerant used in automobiles is R134a. This gaseous material is what helps keep a vehicle cool all year round. It will eventually need to be recharged in vehicles when the temperature in the cabin can no longer stay cool.
Expansion valve or orifice tube: Removes pressure from the liquid refrigerant to allow expansion or change of state from a liquid to a vapor in the evaporator.
Evaporator: a small radiator inside the dashboard that changes the freezing liquid refrigerant to a vapor allowing cold air to enter the condenser which provides cold air to the cabin of the vehicle
Compressor: The power unit of the air-conditioning system that puts the refrigerant under high pressure before it pumps it into the condenser, where it changes from a gas to a liquid.
Condenser: A radiator positioned between the car’s grille and the engine-cooling radiator in which the gaseous refrigerant sheds heat and returns to a liquid state.
Accumulator: positioned on the outlet of the Evaporator. This device helps regulate moisture in the air conditioning system.
Thermostat: Regulates flow of engine coolant from the engine to the radiator
The cabin air filter: serves to clean the air drawn in by your car’s ventilation system.
The blower motor: The fan that pushes heated or cooled air through dashboard vents based on the climate system settings and the fan speed selected.
