Air Conditioning: Receiver.

1. Outlet line to compressor
2. Inlet line from evaporator
3. Cover
4. U-pipe
5. Filter insert
6. Refrigerant oil
7. Drying element
8. Leak detection dye (LDD).

The receiver is basically a reservoir containing a drying agent.

The receiver is located to the right (in front of the right-hand front wheel) in the engine compartment.

To avoid damage to the compressor, the receiver is located on the low pressure side to separate the fluid from the gas. The receiver outlet is located so that only refrigerant in gas form can leave the receiver. Refrigerant in liquid form is collected in the bottom of the container.

The refrigerant gas passes from the evaporator through the inlet line (2) to the receiver on the intake side. The gas flows along the cover (3) and creates an eddy current. The drying element (7) binds the moisture that is absorbed by the refrigerant.

The refrigerant gas collects under the cover, where it is routed out through the opening to the outlet line (1).

Behind the filter insert (5) there is a small hole in the U-pipe (4). The refrigerant oil (6) that collects in the bottom of the receiver is sucked out through this opening and mixed with the refrigerant gas (oil/gas mixture ratio: 3%). The hole plays a very important role in the return of oil to the compressor. This means that the moving parts in the compressor are supplied with sufficient lubrication.

The receiver also contains a small amount of leak detection dye (8).
