Facing complex chemical operating conditions, we provide a stable, continuous, and interlockable process cooling source for the highly fluctuating heat load during reaction and process cooling, ensuring consistent quality and uninterrupted production.
Fluctuations in cold source temperature are prone to affect production consistency and even lead to downtime, and there is an urgent need to implement intelligent capabilities such as interlock protection, data traceability, and operation and maintenance visualization with the DCS system.
The temperature in the workshop and seasonal changes affect the refrigeration conditions, making it difficult for ordinary comfort-type units to adapt to industrial processes, and prone to operational deviations.
Multi-process switching and changes in takt time lead to significant fluctuations in cooling demand. Traditional cold sources may lag or fluctuate in their cooling supply, making it difficult to match real-time demand.
system objective
Stably supply cooling under wide operating conditions and high fluctuating loads to ensure consistency of production temperature, and achieve interlocking and visual integrated control of the docking factory system.
Specific plan
1. Host configuration
Using the Land centrifugal refrigeration unit as the main engine of the process cooling station, it provides stable cooling output driven by electricity. A secondary circuit architecture for process chilled water (or refrigerant) is established, where the main engine side provides stable cooling and the process side distributes as needed, achieving effective buffering of load fluctuations and decoupling operation between the main engine and process sides, thereby enhancing the system's anti-interference capability.
2. Integrated intelligent control system
Deeply integrate the centrifugal chiller unit with the plant-wide Distributed Control System (DCS) or Building Automation System (BAS). The system can intelligently adjust the number of operating units, operating frequency, and cooling tower fan speed based on production plans, environmental temperature, and real-time load, achieving coordinated optimal operation of the entire cooling water system (including chillers, pumps, and cooling towers) and tapping into the overall energy-saving potential.
3. Operation and maintenance management
Visualize equipment operating status, establish a closed-loop management mechanism for maintenance records, respond quickly to operation and maintenance needs, minimize the probability of unplanned downtime, and ensure continuous operation of the production line.
