Henry S-7731, Accumulator, Suction Line, Vert ASME w/ Op. 1" FPT CXN for S-9400 Series, 3-1/8 ODS

The Henry S-7731 Accumulator is a vertical suction line accumulator designed for use in air conditioning and refrigeration systems. Here are the key technical details:

Technical Description

• Model: Henry S-7731
• Type: Vertical Suction Line Accumulator
• Connection Size: 3-1/8" ODS (Outside Diameter Solder)
• Optional Connection: 1" FPT (Female Pipe Thread) connection for S-9400 Series
• Compliance: ASME (American Society of Mechanical Engineers) standards

Features and Functions

1. Liquid Refrigerant and Oil Management:

   • The accumulator provides temporary storage and controlled return of liquid refrigerant and oil to the compressor, preventing compressor damage from liquid slugging.

2. System Efficiency:

   • By metering the return of liquid refrigerant and oil at a controlled rate, the accumulator helps maintain system efficiency and proper crankcase oil levels.

3. Construction:

   • The unit features solid copper ODS connections and a steel shell, making it suitable for use with HFC and HCFC refrigerants, as well as other industrial fluids that are non-corrosive to steel and copper.

4. Heat Exchanger Models:

   • Some models include a heat exchanger coil, which can be used in low-temperature systems to sub-cool the liquid line and improve system efficiency.

5. Mounting:

   • The accumulator comes with mounting legs for easy installation.

Applications

• Air Conditioning and Refrigeration Systems:
  • Ideal for systems where the sudden return of liquid refrigerant down the suction line is possible. It ensures the compressor is protected and the system operates efficiently.

This accumulator is a critical component for maintaining the longevity and efficiency of HVAC systems by managing the flow of refrigerant and oil back to the compressor.
