SSP 131 – Air Conditioning – Audi 100 (1991)
Part I
In Part I you will learn about the basic structure of the refrigeration circuit used in an air-conditioning system. Using simple examples, it explains how cooling is produced and how the cooling capacity in air-conditioning systems is regulated.
Most of the components shown in this section are installed in the Audi 100. In principle, these components also apply to other vehicles, although their appearance and installation position may vary.
Part II
After learning the basic layout of a refrigeration circuit in Part I, Part II of this self-study program introduces the newly developed, fully automatically controlled air-conditioning system in the new Audi 100.
Unlike the previously known control system of fully automatic air-conditioning systems used in Audi vehicles, the new digital control system offers:
More sensitive regulation of the interior climate, even under extreme weather conditions
Individual adjustment options for:
Temperature
Air distribution
Airflow rate
Retention of the last selected settings, even when the vehicle is not in operation
Advantage: High operating comfort of the air-conditioning system.
Thanks to self-diagnosis using the V.A.G 151 fault reader, the new air-conditioning system is extremely service-friendly.
Note:
The new Audi 100 is also available with a newly developed manually controlled air-conditioning system. The manually controlled system uses the same compressor as the fully automatic air-conditioning system and is therefore not described separately.
