The progression of the air conditioning systems in passenger cars, light commercial vehicles and heavy commercial vehicles has been one of the noteworthy advances in the 20th century. It is assessed that more than 85% of the new passenger cars sold across the globe currently have an air-conditioning system, and the number is expected to increase by 2027. Growing sale of vehicles and inclination toward safety and luxury are the main factors which are driving the global automotive HVAC market.
Heating, ventilation, and air conditioning (HVAC) system in a vehicle is utilized to control the interior temperature of the vehicle cabin. HVAC system primarily consist of three subsystems, namely, heating, cooling, and air conditioning, which collaboratively work to offer decontaminated air to the vehicle cabin, guaranteeing thermal coziness to drivers and passengers. HVAC system controls the air temperature, scrutinizes the moisture content in the air, and eradicates unnecessary humidity from the circulating air. Well-established companies, such as Audi, Mercedes, Ford, and BMW, primarily focus on tailored and consumer-friendly HVAC systems. For instance, the BMW 6, 7, 8 & 9 Series supports automatic air conditioning, including air distribution for driver and passengers, fogging sensor, and automatic climate control system.
