Automatic Climate Control (Automatic A/C) in Cars:
The Automatic Climate Control system is the most advanced of all the air conditioning systems in cars. It effectively controls the cabin temperature and humidity levels. In Climate Control, you can set the cabin temperature of your choice. However, the system controls it regardless of the outside air temperature and humidity. Some advanced systems offer Dual-zone climate control with automatic re-circulation mode.
The automatic climate control system provides an individual feel-good climate for the occupants. It automatically controls the temperature, air-flow and air distribution inside the cabin. The climate control system also controls the fan speed and air circulation.
In some cases, the automatic climate control system provides electronic regulation of the air temperature, air flow rate, and air distribution. Some systems provide the defroster nozzles for the windscreen and side windows to eliminate the fogging effect. Nowadays, budget cars also offer an Automatic Air-Conditioner (a step-down version of Automatic Climate Control) with touch screen panel for the ease of use.
Features of Climate Control System:
The automatic climate control system also measures the quality of the cabin air through various sensors. Some provide a separate climate control ECM to control various sensors/actuators such as cabin air quality sensor and humidity sensor. The driver and front passenger can control the temperature separately for themselves. You can also precisely adjust the temperature levels, direction and intensity of the airflow through a touch-screen.
The Climate Control system can also maintain the temperature depending on the sunlight and the quality of the intake air through key-coded settings. Manufacturers use custom acronyms to brand their automatic climate control systems in cars. For e.g. Mercedes-Benz uses the term THERMOTRONIC for the Automatic Climate Control systems fitted in its cars.
Some manufacturers take the climate control to a new level. The driver and front passenger can independently set the temperatures of their choice for their respective areas. The rear passengers can also get better air quality with rear ventilation and re-circulation option.
