Carrier KH71KN163 Accumulator

The Carrier KH71KN163 Accumulator is a mission-critical component engineered for precise refrigerant management in high-demand residential and light commercial HVAC systems. Designed with 7/8" ODF sweat connections, this suction line accumulator acts as a robust fail-safe, preventing liquid refrigerant from reaching the compressor's intake. By utilizing an internal U-tube design with a 0.055-inch protected orifice, the KH71KN163 ensures consistent oil return while effectively managing liquid slugging during system start-ups or low-load conditions. This factory authorized part is optimized for HVAC system reliability, maintaining a stable mass flow rate to protect reed valves and internal scrolls from hydraulic shock. Whether you are performing a compressor replacement or addressing refrigerant floodback issues, this 7/8 inch ODF accumulator provides the high-capacity storage necessary for systems with long line sets or heat pump applications. Its bi-metal, corrosion-resistant construction is built to withstand rigorous field conditions, ensuring long-term HVAC equipment protection and efficient heat pump operation.

• Compressor Protection: Virtually eliminates the risk of liquid slugging and hydraulic damage to internal compressor components.
• Directional Reliability: Features clearly marked inlet and outlet ports with 7/8" ODF fittings for foolproof sweat-in installation.
• Efficient Lubrication: The integrated metering orifice allows for positive oil return without compromising system vacuum or efficiency.
• Enhanced Durability: Robust bi-metal design and premium finish provide superior resistance to moisture and contaminants in the refrigeration cycle.
• System Stability: Absorbs pressure pulsations and manages excess refrigerant flow during unstable operating cycles.

What is the primary function of the KH71KN163 in a refrigeration circuit?
It serves as a temporary reservoir that traps liquid refrigerant and oil, allowing only vapor to return to the compressor to prevent mechanical failure.

Can this accumulator be used in heat pump systems?
Yes, it is ideal for heat pump maintenance and applications where refrigerant flow reversals or varying loads increase the potential for liquid floodback.

Does the KH71KN163 require specific mounting orientation?
Yes, as a vertical suction accumulator, it must be mounted upright as specified by the manufacturer to ensure the internal U-tube functions correctly and avoids oil trapping.
