【Project Background】

As a benchmark enterprise in the telecommunications industry, China Unicom Hebi Branch has always driven sustainable development through technological innovation. In 2023, in response to the national "Dual Carbon" strategy and local, the company comprehensively upgraded the central air conditioning system in its integrated building. By adopting MULTISTACK modular water-cooled flooded oil-free chillers (total cooling capacity: 300RT), it has established a high-efficiency, intelligent, and low-carbon green communication hub.

【Core Advantages】

I. Aerospace-Grade Technology
Equipped with oil-free variable-frequency compressors, achieving zero-friction operation:
・High Energy Efficiency: Outstanding IPLV performance, with over 50% energy savings compared to traditional chillers
・Ultra-Low Noise: Patented technology ensures zero mechanical contact in bearings, creating a quiet and comfortable office environment
・Eco-Friendly: Uses R134a refrigerant, complying with local environmental policies

II. Modular Design
・High Reliability: Independent module operation with "N+1" redundancy design, ensuring 24/7 stable operation of the communication equipment
・Add-on Flexibility: Chiller modules can be installed phase by phase and transported via elevator; future expansion only requires adding module units
・Intelligent Control: Dynamically adjusts the number of operating modules based on different loads, extending equipment lifespan while maintaining high efficiency

III. Full Lifecycle Value
・Low Maintenance Costs: Oil-free system eliminates oil circuit maintenance, requiring only annual evaporator/condenser cleaning at a cost of 1,000-2,000 RMB per session, which is 71% lower than traditional units
・Extended Lifespan: Magnetic oil-free compressors have a design life of 30 years, far exceeding the 15-year lifespan of traditional compressors
・Policy Compliance: Aligns with local Equipment Renewal policies and national "Dual Carbon" goals, contributing to sustainable development
