AI Overview
Key Features and Benefits
- High Efficiency: The tubes are completely submerged in the refrigerant, offering up to five times higher heat transfer coefficients than dry expansion systems.
- Operating Principle: Liquid refrigerant fills about 55-65% of the shell's capacity. Heat from the water (inside the tubes) boils the surrounding refrigerant, which is then separated into gas and returned to the compressor.
- Enhanced Tubes: Typically uses specialized, copper, or stainless steel T-type threaded or finned heat exchange tubes to enhance the surface area and efficiency.
- Stable Performance: The large liquid volume acts as a buffer against drastic temperature/pressure fluctuations, offering operational stability.
Applications and Components
- Applications: Commonly used in HVAC comfort cooling, large industrial refrigeration, oil-free compressor systems, and screw/centrifugal chiller systems.
- Typical Structure: Features a steel shell, multiple copper/stainless steel tube bundles, a liquid level regulator, and a gas-liquid separator at the top.
