8 System and functionality integration 82 �� Figure 8.6: Comfort range of air humidity used for the objective. preferences of the passengers a user control biasing the limits is introduced. Relative humidity in the car cabin [%] for for else Passenger humidity biasing ( ) [%] (8.18) The passenger influence is limited to 30% to stay within the physical limits. This distance of 30% is also the distance giving the maximum value . 8.1.5 Air quality The concentration of carbon dioxide in the air can be used as an indicator for air quality, as seen in Section 2.2.4. Even if it is not measured it can be estimated and used as an objective to ensure fresh air supply.
8 System and functionality integration 83 calculated. Based on the relation shown in Figure 2.6 the air quality objective result (��) is �� for �� ¡ �� for �� for �� Carbon dioxide concentration in the cabin [ �� ] (8.19) �� Carbon dioxide concentration limits [ �� ] As minimum CO2 concentration the value for ambient air, �� , is taken. As maximum a value of �� will give the highest weight of ��. This value is proposed as a maximum for hygienically acceptable air quality [13]. A comparison with the equation given in the European Guidelines for Ventilation Requirements in Buildings [14] is seen in Figure 8.7. �� Figure 8.7: The air quality objective result (�� ) compared to the percentage of dissatisfied people [14]. ��
