Refrigerant Circuit Components Allocation, High And Low Pressure Sides: Reservoir

WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2022 Audi S5 Sportback, 2022 Audi RS 5 Sportback, 2022 Audi A5 Sportback, 2021 Audi S5 Sportback, and 2021 Audi RS 5 Sportback. However, it is still accessible from the selected car via links, so may be relevant.

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 REFRIGERANT CIRCUIT COMPONENTS, REPLACING .

Remove the sealing plugs -A and B- only immediately before 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.
