| An essential prerequisite for alert and safe driving is the perception of comfort in the cabin. This perception of comfort can be improved using air conditioning, especially if external temperatures and humidity are high. Although opening the windows or the sunroof and increasing ventilation obviously contribute to creating a perception of comfort, they also bring certain disadvantages inside the cabin, such as higher noise levels, air currents, exhaust gases, non filtered dust and pollen (an inconvenience for those who suffer from allergies). |
| A well-regulated air conditioning system, together with a well designed heating and ventilation system, can effectively create a perception of comfort and well-being in the cabin by regulating internal temperature, humidity and airflow, in accordance with the prevailing external conditions. This applies to both stationary vehicles as well as those in motion. |
| Other important advantages of air conditioning: |
| t
| The air entering the cabin is purified (the humid fins in the evaporator retain the dust and pollen particles, which are then eliminated by the condenser water). |
| t
| Temperatures measured inside a medium-size vehicle (for example: after a short trajectory, with an external temperature of 30 ºC) |
