General Description - Refrigerant Circuit Components: Reservoir
WARNING: This page is about a different car, the 2022 Volkswagen ID.4 and 2021 Volkswagen ID.4. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
Only installed on A/C systems with a restrictor, at this time this type of A/C system is not installed.
- The reservoir collects the vaporized and gaseous mixture coming from the evaporator to ensure the A/C 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 because there is an oil extraction hole.
- Moisture which has entered the refrigerant circuit during assembly is 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 the refrigerant circuit has been open for a long time and moisture has penetrated inside, or if required due to a specific complaint. Refer to COMPONENTS, REPLACING .
Only remove the plugs -A and B- just before installing.
A desiccant bag in an unsealed reservoir is saturated with moisture after a short period of time and cannot be used.
When installing, note the arrow for the direction of flow if necessary.
