Automobiles are designed and integrated with an HVAC system. This system is just like the one used at homes or in offices The system lets the vehicles interior to be maintained at the desired temperature. There are automotive HVAC controllers in modern vehicles to for controlling the temperatures

A vehicle HVAC system functions together for cooling the interiors of the vehicle.

It is the thought process of most people that HVAC systems create cold air, but that’s not at all right. the HVAC system still works with the similar working principle. Its practical constituent comprises a condenser, compressor, and evaporator.

The main function of an HVAC system is to cool the surrounds to comfort the persons inside the car. With the help of an HVAC systems, one gets cooler and comfortable in summers. So, the purpose of a HVAC remains the same.

Components of Automotive HVAC Systems

Compressor

It is a major components of HVAC systems. It pressurizes the refrigerant for cooling of the air, sensing changes in temperature outside and inside the vehicle, and transporting the air into the condenser

Condenser

The function of a condenser is to decrease the pressure and temperature of hot gasses from the refrigerant as the compressor forces the refrigerant. Another function is the transferring of cooled liquid refrigerant to the receiver. 

Receiver

A receiver is used in automobiles having thermal expansion valve. The receiver separates gas from liquid for avoiding liquid from entering into the compressors.

Evaporator

The evaporator is just behind the dashboard as it takes charge of cooling the air with refrigerant before it is blown into the cabin of the automobile. 

Discussing About the working Principle

The working of an automobile HVAC system is easy to understand. The parts work together in circulating a refrigerant through a low-pressure or a high-pressure closed-loop system.
