Three parallel screw compressor units

A triple-parallel screw chiller utilizes three screw compressors arranged in parallel, integrated into a single refrigeration circuit, and operates collaboratively through a shared chassis, oil system, and control system. The chiller supports multi-stage capacity adjustment, automatically starting and stopping individual compressors based on actual load demand, achieving energy-efficient control under partial-load conditions. The system is typically equipped with high-efficiency heat exchangers, multi-circuit refrigerant distribution devices, and a centralized microcomputer controller to monitor operating parameters in real time and coordinate load distribution between devices. This structure helps reduce floor space and improves the unit's operational stability and maintainability in medium- to large-scale refrigeration or process cooling applications.
