Climate Control would maintain internal cabin temperature and atmosphere in the predefined set points. Heating, ventilation and air conditioning (HVAC) is the technology for indoor and automotive ambient comfort. HVAC facilitates in managing the pleasant climate inside the cabin by controlling the degree of hotness/coolness. The basic principle behind the operation of HVAC unit is conduction and convection. Heat is transferred from a low-temperature region to a high-temperature region in the vehicle, due to the pressure difference. This process of heat transfer is called Refrigeration. Climate control module uses many sensors to detect inside and outside atmosphere of the car, based on that it would maintain the cabin as per drivers setpoint.
