What is the AC Receiver Dryer all about?

The AC receiver drier is a device that only appears in air conditioning systems that employ expansion valves. The cylindrical component is found between the condenser outlet and the expansion valve inlet.

To understand what an AC receiver drier does, one must have a basic understanding how their car’s air conditioner works. Yes, it transforms hot air to cold. But there’s more to it. It does so by circulating a refrigerant that changes phase from liquid to gas and back again when forced through the system. The cold liquid refrigerant is squeezed through an evaporator, removing heat from air pulled in from the car’s cabin. Once cooled and dried, a blower pushes the air back out into the car. The warmed and vaporized refrigerant circulates through a compressor, where the vapor is cooled and transformed back into a liquid. And the process is repeated, over and over again, until you shut the AC off.

Th receiver drier serves as a filter to remove any moisture and contaminants that get into the AC system during this process. ACR Drier has three parts:

• The Container: Acts as a temporary storage for oil and refrigerant during periods of low cooling demand.
• The Desiccant Sack: Usually filled with silica gel, it removes moisture from the refrigerant. It also traps other debris, preventing clogs.
• Inlet / Outlet: Allows the continuing flow of refrigerant around the system.
