Car Air Conditioning Accumulators

Car A/C 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.
