Key Characteristics of Flooded Chillers
- Design: The shell-and-tube evaporator is filled with liquid refrigerant, and water passes through the tubes. An accumulator is used to prevent liquid from returning to the compressor.
- High Efficiency: By keeping the heat transfer surface fully wetted, it achieves higher overall efficiency and closer approach temperatures (often less than 3°C) compared to DX systems.
- Capacity: Often paired with screw compressors for high-capacity applications, with capacities commonly in the range of 340.0–1780.0 kW.
- Applications: Commonly used in large commercial, industrial, and petrochemical facilities, such as large hotel central air conditioning, supermarkets, and food processing.
- Maintenance & Cost: Flooded chillers are generally more expensive and require more refrigerant than DX units, with higher maintenance costs due to complex oil management.
Key Differences from DX Chillers
- Refrigerant Management: In a flooded system, liquid refrigerant is maintained at a constant level via a float valve, whereas in a DX system, the refrigerant is fully vaporized, notes and.
- Performance: Flooded evaporators generally offer higher heat transfer coefficients, making them more suitable for high-load applications, as explained in.
