Volkswagen Golf Service & Repair Manual: 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. |
|
|
|
| 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. |

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 ...
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 ...

Safety precautions during a road test
using test and measuring equipment
Observe the following if test and measuring equipment is

O-ring
These O-rings seal the joints between the individual
components of the refrigerant circuit.
Use only seals that are resistant to refrigerant R134a and
its associated refrigerant oils. This is assured by using
genuine replacement parts.

Water content
Only very small amounts of water are soluble in liquid
refrigerant. On the other hand, refrigerant vapour and water
vapour mix in any proportion.
Any water present in the refrigerant circuit will be carried
along as droplets. The dessica ...
