Climate Control systems help to maintain a steady and pleasant preset temperature can be controlled using buttons on the control panel. It is a bit like setting the thermostat in the house to adjust the central heating system constantly to maintain a set temperature inside the house but only more advanced and sophisticated with state of the art technology. Climate Control has many sensors that work in simultaneously to ensure a pleasant temperature inside the vehicle at all times there are different type of sensor. A Temperature sensor is installed on top of the evaporator housing to measure the external ambient temperatures. Another temperature sensor is located in the middle of the control panel measuring the internal temperature levels. Two more temperature sensors are installed in the right and the left air ducts near the feet. An ultraviolet photoelectric sensor located on top of the dashboard towards the far right. The cars velocity is measured by a speed sensor, and the entire climate control system is designed to achieve the desired ambient temperature inside the vehicle to provide with a delightful drive experience. Advanced climate control devices can be operated using voice commands as well and takes care of defogging or demystifying as well. Some automobiles have a ventilation air filter, which cleans the external air that enters the passenger compartment by way of the air inlet. Many automobiles employ tinted glass to scale down the ultraviolet rays transmission to the interior. Thus keeping the temperature inside the car even and cozy. This includes the cars heating and cooling systems as well as their controls. Most of the modern cars have computers installed to regulate the climate inside the vehicle. A simple system, which is a combination of air conditioning and heating, are the stock equipments installed already by the manufacturer. The climate control system also takes care of the fan speed and air circulation. Humidity controls, and clean air systems integrated with efficient air cleaners and air filters are a part of the advanced climate control systems today. Air conditioning systems or climate control systems require regular maintenance to work efficiently. If not maintained, it may affect the cooling or the heating of the vehicle making the temperature inside undesirable. Climate control systems are different from air conditioning systems as they achieve a lot more than just cooling down the automobile. Most of the climate control systems work electronically with the help of computers and electronic sensors, which ensure a pleasant and comfortable ride.
