About Screw Chiller

A screw chiller is a refrigeration system that uses ahelical screw compressorto compress refrigerant gas, producing chilled water for cooling in applications like central air conditioning or industrial processes. Key features include its high efficiency, reliability, and long service life, making it suitable for high-load, long-term operations. These systems are available in air-cooled and water-cooled configurations and can feature multiple compressors for redundancy and load balancing.

How it works

Compressor:The central component is thescrew compressor, which has two intermeshing helical rotors that compress gas as they rotate.
Refrigerant cycle:This compression process drives the refrigeration cycle, which involves an evaporator, refrigerant, and expansion valve to cool a fluid.
Heat removal:
- Water-cooled versionsuse a cooling tower to remove heat from the system.
- Air-cooled versionsrelease heat directly into the surrounding air.
Capacity control:The chiller's capacity can be controlled in several ways, such as using multiple steps or a variable frequency drive (VFD) system to adjust the compressor speed and enhance energy efficiency.

Key characteristics

High efficiency:Screw compressors are known for their efficiency, especially at partial loads when paired with VFDs.
Reliability and durability:These systems are built for long-term, continuous use with a service life that can exceed 100,000 hours.
Versatility:They are used in a wide range of applications, from large central AC systems to industrial cooling, and come in various capacities.
Modular design:Many units have a modular design, sometimes using multiple refrigeration circuits for redundancy and load balancing, so if one fails, the others can continue to operate.
Advanced control:Modern screw chillers often feature advanced control systems, such as aSiemens PLCcontroller with a touch screen for precise monitoring and diagnostics.
