Here are the major AC Parts & Components in Volvos. Here are photos and descriptions from the eEuroparts catalog. All these are covered in detail on eEuro’s outstanding AC components page.
Moving off the clutch gap and recharging low refrigerant procedures, which themselves are absolutely viable “low-hanging fruit” AC possible fixes for your Volvo air conditioning problems, let’s take a longer look at AC components:
The compressor does the heavy lifting in all A/C systems, and is powered by the engine by means of belt and pulley.
After the cooled down compressed liquid leaves the condenser, it will go into the receiver drier, also sometimes known as the accumulator.
Expansion Valve (or Orifice Tube in some systems)
These AC parts are positioned right in front of the A/C Evaporator, and are the key point in the process where the refrigerant takes a turn for the colder.
From the compressor, hot high-pressure gas flows to the condenser, which is the large aluminum radiator on the front of your car with metal pipes going to it.
Now that the vapor/liquid refrigerant is able to get some elbow room to expand, it continues the process on through the evaporator.
AC oil operates as a lubricant and heat removal medium.
Finally, there’s the miscellaneous air conditioning pipes, AC lines and seals
