2005 Volvo S80: Necessary to Replace Receiver/Drier For A/c?

When the Vehicle A/C system is disassembled or open or taken Apart.
Its mostly necessary to replace the Receiver/ Drier part.

Yes, the receiver/drier contains what is called a deccisant bag, which is designed to absorb moisture in the system. When you open up the system to replace any parts, the deccisant bag fills with moisture from the atmosphere and its effectiveness is greatly reduced.

You can decline to have it replaced, but if you do so then there will be no warranty on the job of getting the proper cooling from A/C system, as you have declined required work. The system likely will not get as cold either since the receiver drier can no longer pull the moisture out of the system.

So getting this component replaced.If the A/C Repair center is recommending it.

This details will help.
Thanks.

For more details regarding Replacing Accumulator/Receiver Dryer read as follows :---

WARNING

Do not uncap the drier or accumulator until the unit is ready for installation. Remember: the desiccant attracts moisture from the surrounding air.

WARNING

Only EPA-certified technicians can purchase R-12 refrigerant, since proper recovery and recycling techniques are required to prevent damaging the environment. Improper disposal of R-12 refrigerant can result in a fine.

The receiver drier is usually located under the hood of the car. The drier should be placed where it can be kept as cool as possible. At least one independent manufacturer of aftermarket systems mounts the drier inside the evaporator case where it is always surrounded by the cool air of the evaporator.

The inlet and outlet fittings of receiver driers may be 3/8-inch SAE flare, 5/16-inch barb, O-ring, or block type. Also, receiver driers may have specially formed inlet and outlet tubing before the fitting provisions. As a rule of thumb, it is recommended to replace a receiver drier with an exact duplicate. This is particularly important to ensure refrigerant capability with the desiccant.

Manufacturers' recommendations should be followed when mounting a drier. For proper operation, the vertical-type drier must be mounted so that it does not incline more than 15°. The inlet of the drier must be connected to the condenser outlet and the outlet of the drier to the evaporator metering inlet.

The word IN is generally stamped on the inlet side of the drier. If the inlet is not stamped, an arrow indicating the direction of refrigerant flow should be visible. Remember that the refrigerant flows from the condenser bottom toward the metering device inlet. If the drier is connected in reverse, insufficient cooling will result.

As a result of improper handling or shipping, the internal parts of the drier may become dislodged and cause a partial restriction within the drier. This condition is indicated by a marked temperature change between the inlet and the outlet of the tank. If the restriction is great enough, frosting occurs at the drier outlet.

If the pickup tube is broken because of rough handling, abnormal flashing of the gas occurs in the liquid line. This is the same indication that is evident due to a low charge of refrigerant. In either case, a new drier must be installed.

Screens are located in the inlet of the metering device, the inlet of the compressor, and in the receiver drier. The screen in the thermostatic expansion valve and compressor can be cleaned or replaced. If the screen in the fixed orifice tube or drier becomes clogged, the entire component must be replaced.

How to Inspect Vehicles Accumulator/Receiver Dryer ?

First read and know what is Accumulator and what is its working operation:----

A tank located in the outlet of the evaporator to receive refrigerant that leaves the evaporator. A component used to store or hold liquid refrigerant in an air-conditioning system. This device is constructed to ensure that no liquid refrigerant enters the compressor.
A device that cushions the motion of a clutch and servo action in an automatic transmission.
A register or storage location that forms the result of an arithmetic or logic operation. Commonly used when a series of calculations are to be used.

This is how Accumulator looks:---

Now Go through this Inspecting procedure:----

Air conditioners use either a receiver dryer or an accumulator. These devices vary slightly as to function and differ as to where they are installed in the system:

A receiver dryer is installed in the high side.
An accumulator is installed in the low side.

A receiver dryer fills and siphons liquid refrigerant from the bottom.

An accumulator separates vapor and liquid. It pulls off vapor from the top. Courtesy of Ford Motor Company.

Some systems have a sight glass on the receiver dryer or in the high pressure liquid line so that unwanted vapor bubbles can be spotted as the system operates. This can give a quick check of whether the refrigerant level is too low. A sight glass is only found on the high pressure side of the system. Also, look for signs of leakage. If you find leaks, replace the part.

An accumulator cannot be serviced. Inspect it to see if it is defective or wet, if so, the entire unit must be replaced. Also check the expansion tube that serves as a metering device to the evaporator. If the expansion tube is clogged, it is again necessary to replace the accumulator.
