What Is a Receiver Drier?

The receiver drier is located between the condenser outlet and the expansion valve inlet on the high-pressure side of the air-conditioning system. Its main function is to remove moisture and contaminants from the refrigerant. This prevents corrosion, blockages, and performance issues, safeguarding all other air-conditioning components.

What Is an Accumulator?

The accumulator sits on the low-pressure side between the evaporator outlet and the compressor suction port. It prevents compressor damage caused by liquid refrigerant slugging. By ensuring that only gas reaches the compressor, the accumulator maintains system efficiency and prolongs compressor life.

Why Are Driers & Accumulators So Important?

  • Moisture Removal: Protects the system from corrosion and ice formation.
  • Contaminant Filtering: Prevents internal damage and blockages.
  • Compressor Protection: Avoids liquid slugging and ensures gas-only flow.
  • System Performance: Enhances cooling efficiency and extends component lifespan.
