DAC Worldwide’s ACR Suction Line Accumulator Cutaway (373-701) is a professionally sectioned example of an accumulator commonly installed in the suction line of air conditioning, heat pump, and refrigeration systems.
A suction line accumulator helps protect the compressor from liquid refrigerant entering through the suction line. Because compressors are designed primarily to compress vapor, a sudden return of liquid refrigerant can cause liquid slugging, lubricant dilution, and mechanical damage.
The accumulator temporarily collects liquid refrigerant and oil carried by the suction vapor. Refrigerant is allowed to vaporize before returning to the compressor, while a controlled oil-return passage helps move collected lubricant back into the suction stream.
A carefully planned cutaway exposes the accumulator shell, inlet and outlet connections, internal tube assembly, liquid-storage area, oil-return passage, and refrigerant-flow path. The internal configuration helps prevent accumulated liquid from flowing directly into the compressor suction connection.
Color coding, directional-flow arrows, and numbered callouts help learners trace refrigerant and oil movement through the device and understand how an accumulator responds to changing system conditions.
The ACR Suction Line Accumulator Cutaway supports instruction in compressor protection, refrigerant migration, liquid floodback, oil return, heat pump operation, component installation, preventive maintenance, and troubleshooting.
The cutaway is mounted on a modular display panel for convenient classroom and laboratory use. It can be used independently with a compatible tabletop mounting support or combined with other DAC Worldwide cutaways on optional display and storage frame assemblies.
The equipment is cleaned, primed, and finished with a durable urethane coating to withstand frequent use. Carefully selected cutaway areas expose the accumulator’s internal components while preserving their relationship and operating principles.
Actual component brands and models may vary depending on availability.
Pair the ACR Suction Line Accumulator Cutaway with additional DAC Worldwide HVAC/R cutaways to examine compressor protection, refrigerant control, oil management, and complete system operation.
