Carrier KH71KK120 Accumulator

The Carrier KH71KK120 is a high-performance suction line accumulator engineered specifically for HVACR systems using 5/8" connections. Designed for high-pressure environments with a 235 PSI working pressure rating, this OEM replacement part is critical for protecting the compressor from liquid refrigerant floodback. As a veteran technician knows, maintaining the integrity of the suction line is paramount; the KH71KK120 utilizes an internal U-tube design with a precision metering orifice to ensure a controlled oil return, preventing oil starvation and subsequent mechanical failure during low-ambient cooling or defrost cycles.

Constructed with a bi-metal body and a corrosion-resistant powder coating, this Carrier accumulator is built to withstand harsh outdoor conditions. It is frequently applied in Carrier, Bryant, and Payne heat pumps and refrigeration units where fixed-orifice expansion devices or varying heat loads are present. Integrating the KH71KK120 into your system provides an essential refrigerant management buffer, capturing unevaporated liquid and allowing only saturated vapor to enter the suction port. This safeguard is indispensable for extending HVAC system longevity and ensuring reliable refrigeration performance in commercial or residential applications.

• Enhanced Compressor Protection: Effectively prevents liquid slugging by separating liquid refrigerant from the suction gas.
• Optimized Oil Return: Features a filtered pickup orifice to maintain proper lubrication levels throughout the refrigerant cycle.
• Direct OEM Compatibility: Ensures a precise fit and reliable performance in Carrier heat pump and air conditioning systems.
• Robust Build Quality: High 235# working pressure capacity and bi-metal construction for maximum durability.
• Versatile Installation: Supports both sweat and braze connection types for efficient field replacement.

When should I replace the Carrier KH71KK120?
Replacement is recommended if you detect external corrosion, refrigerant leaks at the base, or after a major compressor burnout to ensure no acidic oil or debris from the previous failure remains in the suction line.

Can this accumulator be used with any refrigerant?
It is designed for standard high-pressure refrigerants compatible with its 235 PSI rating. Always verify that your system’s operating pressures do not exceed the accumulator's maximum specifications.

What happens if the oil return orifice is blocked?
A blocked orifice prevents oil from returning to the compressor, which can lead to overheating and mechanical seizure. Always use dry nitrogen when brazing to prevent carbon scaling that could clog the internal screen.
