Air Conditioning System — Description and Warnings (Opel Omega A)

1. Air conditioning is standard on later high-spec models and optional on lower-spec models. Together with heating, the system allows the air inside the car to be maintained at any desired temperature, and also reduces the humidity of incoming air, helping to cool even when it is not needed.

2. The refrigeration part of the air conditioning system works like your home refrigerator. The compressor, connected by a belt from the crankshaft pulley, forces refrigerant in gas form from the evaporator. The compressed refrigerant passes through the condenser, where it loses heat and turns into a liquid. After this, the refrigerant returns to the evaporator, where it absorbs heat from the air. The refrigerant becomes a gas and the cycle repeats.

3. Various auxiliary controls and sensors protect the system from overheating and overpressure. Idle speed is further increased when the system is on to compensate for the load from the compressor operation.

4. Although the coolant is not poisonous, it produces a highly toxic gas when ignited. Liquid spilled on the skin causes frostbite.

5. It is advisable to have all air conditioner maintenance work performed by a specialist.

6. Do not overheat the air conditioning pipes above 110°C, for example when welding or drying the body.

7. Do not use the air conditioner if it is damaged.
