Being comfortable while driving leads to better concentration and safe driving. Air conditioning makes drivers and passengers more comfortable when temperatures or humidity are high. While opening the windows or sunroof or increasing the air flow can make vehicle occupants more comfortable, it also exposes them to more noise, draughts, exhaust, pollen and dust. A well-designed heating and air conditioning system can increase comfort by controlling the temperature, humidity and air flow inside the vehicle. This is done both when the vehicle is moving and when it is stationary. Air conditioning also offers these advantages:It cleans the air that enters the vehicle interior. The damp fins on the evaporator collect dust and pollen, which is then removed by condensation. Temperatures in a mid-size vehicle (for example: after a short drive, outside temperature 30 C (86 F) in the shade and the vehicle exposed to sunlight). |
| Area | Temperature with A/C System in Celsius (Fahrenheit) | Temperature without A/C System in Celsius (Fahrenheit) |
| Head area | 23 C (73 F) | 42 C (107 F) |
| Upper body area | 24 C (75 F) | 40 C (104 F) |
| Foot area | 30 C (86 F) | 35 C (95 F) |
Environmental InformationVehicles manufactured after 1992 have air conditioning systems that use refrigerant R134a. This refrigerant does not contain chlorine and does not deplete the ozone layer. Refrigerant R12 was used through 1992. Due to its chlorine atoms, this CFC has a high potential for depleting the ozone layer as well as a tendency to increase the greenhouse effect. Conversions are offered for existing systems filled with the ozone-depleting substance R12. Refer to Repair Manual for A/C systems with refrigerant R12. This repair manual is only available in hard copy. For environmental protection reasons, refrigerants must not be released into the atmosphere. For laws and regulations. Refer to → Chapter "Laws and Regulations". |
