Volkswagen Golf Service & Repair Manual: Receiver

Volkswagen Golf Service & Repair Manual / Air conditioning system with refrigerant R134a / General information on refrigerant circuit / Refrigerant circuit components / Receiver

The receiver collects the liquid droplets and directs them in a continuous stream to the expansion valve. Moisture which has entered the refrigerant circuit during assembly is collected by the dessicant bag in the receiver.

Note

Renew the receiver if the refrigerant circuit has stood open for any length of time (more than the normal repair time) and moisture has entered the system, or if it is required because of a specific complaint → Chapter.

Do not remove sealing plugs until just before installation.

The dessicant bag in an unsealed receiver will become saturated with moisture within a short time and is then unusable.

When installing, observe arrow indicating direction of flow, if applicable.

Receiver

The new generation of receivers are mounted directly on the condenser and contain a dryer cartridge.

Note

Renew the dryer cartridge if the refrigerant circuit has stood open for any length of time (more than the normal repair time) and moisture has entered the system, or if it is required because of a specific complaint → Chapter.

Remove the dryer cartridge from its packaging only immediately before installing it.

A dryer cartridge in unsealed packaging will become saturated with moisture within a short time and is then unusable.

Restrictor

The restrictor creates a restriction. This restriction limits the flow, separating the high-pressure and low-pressure sides in the refrigerant circuit. Upstream of th ...

Expansion valve

The expansion valve atomises incoming refrigerant and regulates the flow so that, depending on the heat transport, the vapour does not become a gas until it reaches t ...

Distribution of the refrigerant circuit components and their influence on the high-pressure and low-pressure sides
On the high-pressure side, there are the condenser, the receiver and the restrictor or expansion valve that acts as the separation between the high-pressure fluid and low-pressure fluid sides. High pressure is created because the restric ...
