On cars of the fifth series «x5» with body «E53» the air conditioning system in the cabin is included in the basic package (air conditioner), automatic air conditioning is provided in a special or export configuration, as well as as additional equipment. At high speeds, the condenser is cooled only by the oncoming air flow. At low speed and while stopped (idling) an additional fan cools the condenser, which is activated at a speed of less than 70 km/h, at a speed of more than 80 km/h it is switched off.
A general view of the car's air conditioning system is shown in Figure 17.1, the cooling circuit is shown in Figure 17.1. 17.2, the air conditioner control unit is shown in figure 1.70, the automatic air conditioner control unit and the direction of air flow are shown in figure 1.70.
The location of the actuators of the heater / air conditioner unit is shown in Figure 17.3. When installing the actuator, align the appropriate damper actuator shaft with its actuator shaft. The performance difference between «Basis» And «High», is that the system «High» has an additional solar sensor, fogging sensor, system sensor «AUC», ventilation temperature sensor.
Systems control panels «Basis» And «High» shown in figures 1.70 and 17.21 respectively.
