Receiver Driers / Accumulators: What do they do?
The receiver/driers act as temporary storage containers for oil and refrigerant when neither are needed for the system operation. This is the "receiver" function of the receiver/drier.
• Removes moisture from the system
• Filters refrigerant
• Stores refrigerant
TECH TIP: AC Maintenance - Always flush the A/C system to remove any contaminates and replace any parts that cannot be flushed. Always replace the drier anytime the AC system is opened. It is also a good practice to use inline suction filters to help catch any foreign material.
