The automotive climate control system, commonly located within the engine compartment, regulates cabin temperature and humidity. It typically consists of a compressor, condenser, evaporator, expansion valve or orifice tube, and related components working in a closed refrigerant loop. For example, the compressor pumps refrigerant, while the evaporator absorbs heat from the cabin air, providing cool air through the vents.
A comfortable cabin temperature significantly enhances driver alertness and passenger comfort, especially during extreme weather conditions. This system’s development has evolved considerably over time, progressing from basic ventilation to sophisticated climate control that automatically adjusts to maintain pre-set temperatures. This evolution reflects the growing emphasis on passenger comfort and safety in vehicle design.
