Data Center Natural Cooling Dry Cooler

Data Center Natural Cooling Dry Cooler

The dry cooler is designed to maximize natural cooling utilization, prioritizing it as the primary cooling source to supply chilled water to the data center, with the mechanical refrigeration system serving only as auxiliary cooling.

Key Manifestations of Design Logic

Cooling Source Priority Setting: The control system continuously monitors outdoor temperature and humidity. When outdoor natural cooling capacity meets demand (e.g., sufficiently low temperatures), the dry cooler operates at full capacity to directly supply low-temperature chilled water to the equipment room.

Mechanical Refrigeration as Auxiliary: The mechanical refrigeration system activates only when ambient temperatures exceed natural cooling capacity, working in tandem with the dry cooler to maintain stable chilled water temperatures.

Seamless Switching Mechanism: The system features automatic switching without manual intervention. It facilitates smooth transitions between natural and mechanical cooling, ensuring continuous data center cooling while preventing energy waste.

Core Value Delivered by This Design

Ultimate Energy Efficiency: Significantly reduces mechanical refrigeration compressor runtime, lowering overall cooling system energy consumption by over 30%. In colder regions, near-year-round natural cooling can be achieved.

Operational Stability: Mechanical refrigeration serves solely as backup and supplemental capacity, reducing high-load operating periods. This indirectly lowers equipment failure risks and enhances the cooling system's overall reliability.

Cost Optimization: Long-term energy savings directly reduce electricity expenses. Simultaneously, diminished wear on mechanical refrigeration equipment lowers future maintenance costs.
