Two parallel screw compressor units

Two-parallel screw units utilize twin-screw compressors in a parallel configuration, achieving coordinated operation through a shared refrigeration circuit and control system. These units are typically equipped with a centralized control module that automatically adjusts compressor start/stop and capacity output based on actual load, thereby improving energy efficiency. The system supports alternating operation modes, which helps balance mechanical wear and extend equipment life.

The unit structure utilizes industry-standard components, including the oil separation system, condenser, and evaporator, and can integrate multi-stage capacity adjustment. This configuration is suitable for medium- to large-scale refrigeration or heat pump applications, providing stable cooling and heating output while minimizing the impact of a single unit failure on overall system operation.
