HVAC system utilizes a heater to warm the air and uses an evaporator to cool the air through refrigerant gas evaporation. The instance creates an ideal cabin temperature according to the operation of the apparatus panel.
FREMONT, CA: Earlier generation vehicles mostly employed an air conditioner. Still, it only cooled the cabin air and could not efficiently control the air temperature, particularly in winters. This point caused discomfort to the occupants. To expand this situation, automotive engineers developed the second-generation Heating, Ventilation, and Air Conditioning (HVAC) systems for vehicles.

Manufacturers employ HVAC technology to attain better vehicular environmental ease. Therefore, it preserves the thermal indoor air quality. HVAC also offers heating of air along with the car’s air conditioning system. The air is heated through the temperature from the engine’s cooling structure. Today, most vehicles have an HVAC system.
Working of HVAC System:
The manufacturers adopt the technology to offer a comfortable setting in vehicles. Furthermore, it delivers thermal comfort and enhances indoor air quality. HVAC works on the principles of heat transfer, thermodynamics, and fluid mechanics. It is a sub-division of the air conditioning system and comes with a compressor, blower unit, a compressor, and ancillaries.

Another vital function of the air conditioner is defogging the window and dehumidifying the cabin. A modern car air conditioner primarily cools the air, slightly lower than the user sets to prevent the window from fogging. Later, the system corrects the temperature as set by passing cooled air over the heater.
Heat Exchanger
The heat exchanger competently transfers the heat from one to another medium without having direct contact or mixing either of them. The manufacturers make use of heat exchangers in air conditioning, refrigeration, and power plants.
The heat exchanger applied in the internal combustion engine is a good example. The radiator coils facilitate the engine coolant to flow through them. Still, the air flows through the coils and allows the coolant to cool down. In the same period, it heats the air that comes into the cabin. In an air conditioner, there are dual heat exchangers. One comes with an evaporator unit and contains the refrigerator liquid that drifts into the low-pressure system tubes from a small hole.
