Accumulator / Receiver Driers
Accumulators and receiver driers are the components of your auto AC system that manage the flow of refrigerants through the system. Their job in AC operation is to isolate and contain corrosive moisture to protect the internal workings. As long as the system remains closed, these components are unlikely to need service, but there are times when you'll need to replace these parts.
If your AC compressor fails you should also replace your accumulator/ receiver drier. Failing to do so could result in costly and extensive repairs.
When a receiver drier or accumulator fails, it is usually due to:
- Debris inside the system from a malfunctioning compressor
- Damage to the desiccant bag which can release desiccant material into the system where it mixes with the refrigerant and will circulate throughout the system. The desiccant breaks down into granular particles and can clog every part of your auto AC system.
Which part do you need?
Whether you car needs an A/C accumulator or a receiver drier depends on the type of system in your vehicle. The two parts perform similar functions. AC accumulators are typically found in Ford or GM cars that have an orifice tube, not a thermal expansion valve. The accumulator monitors, filters, and controls the flow of refrigerant through the system and uses desiccants to remove moisture.
A receiver drier is found in AC systems that have thermal expansion valves. It's typical in foreign cars and after-market systems. Much like an accumulator, the receiver drier monitors and controls the refrigerant in the system. It also separates the gas from the liquid to prevent damage to the compressor and filters out any debris.
