Refrigerant Circuit Components: Reservoir

WARNING: This page is about a different car, the 2014 Volkswagen Touareg, 2013 Volkswagen Touareg, 2012 Volkswagen Touareg, and 2011 Volkswagen Touareg. However, it is still accessible from the selected car via links, so may be relevant.

All components of the refrigerant circuit submitted for quality observation are always to be sealed (use original sealing caps of original part).
Replace damaged or leaking components of refrigerant circuit. Refer to COMPONENTS, REPLACING .
To date, the original parts (compressor, reservoir, receiver/dryer, evaporator and condenser) have been filled with nitrogen gas. This charge is being gradually discontinued. There is little or no pressure equalization when removing the sealing plugs from the original part.

The reservoir collects the vaporized and gaseous mixture coming from the evaporator to ensure the compressor only receives gaseous refrigerant. Gaseous refrigerant is formed from the vapor.

The refrigerant oil flowing in the circuit is not retained in the reservoir as it has an oil drilling.

Moisture which has entered the refrigerant circuit during repairs will be collected by a filter (desiccant bag) in the reservoir.

Gaseous refrigerant is extracted with oil by the A/C compressor.

NOTE:

Replace the reservoir if refrigerant circuit has been open for a long time (beyond the normal repair time) and moisture has penetrated inside, or if required due to a specific complaint. Refer to COMPONENTS, REPLACING .

Remove sealing plugs -A and B- only immediately prior to installing.

A desiccant bag in an unsealed reservoir is saturated with moisture after a short period of time and unusable.

When installing, note arrow for direction of flow if necessary.
