Car Air Conditioning Accumulators
The air conditioning accumulator is part of the car air conditioning system. Valeo offers OE (Original Equipment) quality accumulators for the automotive aftermarket.
The accumulator has a similar function to the receiver drier but works on the gaseous side of the car A/C loop. The car A/C accumulator plays an important role in protecting system components from moisture and contaminants. The car air conditioning accumulator is located on the low-pressure side of the circuit between the evaporator outlet and the compressor suction port.
The accumulator has different roles:
- Protecting the compressor, preventing car compressor failure due to liquid slugging
- Retaining moisture and contaminants from the system throughout the accumulator's lifetime
- Ensuring oil return
- Ensuring only refrigerant returns to the compressor
Valeo Info: The accumulator is a filter drier that must be replaced approximately every 3 years, or whenever the car A/C circuit is opened.
