Henry S-7741, Accumulator, Suction Line, Vert ASME (Standard Model), 4-1/8 ODS

The Henry S-7741 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-7741
• Type: Vertical Suction Line Accumulator (Standard Model)
• Connection Size: 4-1/8" ODS (Outside Diameter Solder)
• Compliance: ASME (American Society of Mechanical Engineers) standards

Features and Functions

1. Liquid Refrigerant and Oil Management:

   • The accumulator is designed to provide temporary storage and controlled return of liquid refrigerant and oil to the compressor. This helps prevent compressor damage from sudden surges of liquid refrigerant, known as 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.
