5 Parts of a Car's HVAC System

1. Compressor

The most important part of a vehicle's air conditioning system. The compressor's job is to take the low-pressure gasses and compress them into a highly pressurized hot gas. It will also sense the fluctuating temperature changes both inside and outside of the car as well as monitor and control the temperature output from the system. Once this process is completed, the air is then moved to the condenser.

2. Condenser 

Once the air is in the condenser, it is subsequently cooled down and depressurized. Refrigerant temperature is reduced, and it is changed from a gaseous to a liquid state. After the refrigerant is condensed, it turns into a highly pressurized cool liquid. Once the condensing process is completed, the condenser is responsible for routing the cooled refrigerant to the receiver/dryer/accumulator to be separated.

3. Receiver/Drier/Accumulator 

Determining whether your vehicle has a receiver, dryer, or accumulator is dependent on the make and model of your vehicle. Vehicles with a thermal expansion valve will have a receiver or dryer while those with an orifice tube will have accumulators. 

The purpose of receivers and dryers are filtering units that are intended to separate gasses from liquids. This part receives and stores the refrigerant liquids that came from the condenser. If your car is fitted with an accumulator, it will monitor and regulate refrigerant levels going into the evaporator. The intense gas pressures in the hydraulic system allow the accumulator to collect pressurized fluids; resulting in compressed gasses. 

4. Metering Device

Located between the condenser and evaporator, this can either be an expansion valve or an orifice tube. The role of either an expansion valve or orifice tube is to lower the pressure of the refrigerant, which in turn, drops its temperature. As a unit, this part measures the temperature and pressure within the HVAC system and determines the proper amount of refrigerant that can be sent into the evaporator coil.

5. Evaporator Coil

Here, the refrigerant is reverted back into a gaseous form. This results in a cooling effect. As air passes across the evaporator, the air is cooled and dried. This component is responsible for cooling the air with the refrigerant before it is dispersed throughout the interior of the vehicle, and is one of the most important parts of the HVAC system.
