MULTISTACK Jiefeng Completes Chiller Retrofit for China Unicom Liaoning Headquarters

Recently, MULTISTACK Jiefeng successfully completed the chiller retrofit project at the headquarters' north campus of China Unicom Liaoning Provincial Branch. The project delivered seven MVRW175 modular variable frequency scroll chillers in batch. Using a standardized modular splicing construction solution, the installation provides a solid equipment foundation and technical support for the safe, stable, and efficient operation of the communication room.

The retrofit took place at the Shenyang Unicom Building equipment room. Seven of MULTISTACK Jiefeng's new-generation variable frequency modular chillers were seamlessly spliced and integrated into a compact layout. The equipment is arranged neatly and uniformly, forming an integrated unit that maximizes the use of available space. The entire installation is standardized, clean, and aesthetically pleasing, perfectly meeting the requirements for centralized cooling and集约化deployment in communication rooms. This project sets a benchmark example of modular variable frequency chiller splicing in the industry.

The chillers are equipped with high-performance variable frequency scroll compressors, offering full-condition wide-frequency load regulation from 20% to 100%. They can intelligently and adaptively adjust output based on real-time cooling load in the equipment room. Compared with traditional cooling equipment, they maintain high energy efficiency even under partial load conditions, significantly reducing overall energy consumption. This precisely meets the core operational requirements of communication rooms: 24/7 uninterrupted operation, low energy consumption, and high stability.

The units feature an innovative industry-leading internal large-pipe water circuit design, paired with high-efficiency plate heat exchangers. This optimizes water flow conditions within the piping, reduces pressure drops, and greatly improves overall heat exchange efficiency. Meanwhile, the internal piping structure simplifies on-site construction processes, shortens installation cycles, and effectively saves project construction costs and subsequent operation and maintenance expenses.

As the inventor of modular chillers, MULTISTACK Jiefeng has been deeply rooted in the refrigeration industry for many years. Leveraging its mature intelligent control system and modular architecture advantages, the company ensures long-term, stable operation of communication rooms. The chillers support independent start/stop of multiple modules, intelligent linkage and coordinated control, and maintenance without shutdown—perfectly suited for carriers' around-the-clock, uninterrupted operation and maintenance scenarios.

In this Shenyang Unicom retrofit project, the combination of MULTISTACK Jiefeng's new-generation variable frequency modular chiller's robust performance and standardized, exemplary splicing construction has successfully completed the upgrade of the equipment room's cooling system. It sets a replicable and referenceable application example for the telecommunications industry, enabling efficient, energy-saving, green, low-carbon, safe, and stable routine operation of communication and computing equipment rooms.

MULTISTACK JF Empowers China To***co Hunan’s Digital Transformation

China To***co Hunan’s Digital Flavor Blending Project is a benchmark initiative in the digital transformation of the to***co industry and a core pillar of the enterprise’s high-precision “intelligent brain”. The project imposes extreme requirements on the stability, accuracy, and continuity of the cooling system. Any shutdown or temperature fluctuation could invalidate experimental data or damage production lines.

MULTISTACK JF has custom-tailored its latest-generation MVW series magnetic levitation chillers for the project, providing a professional and reliable cooling solution to safeguard high-end precision manufacturing.
As MULTISTACK JF’s next-generation flagship product, the fifth-generation MVW-FE series magnetic levitation centrifugal chiller precisely meets the project’s stringent demands, delivering full protection through five core performance advantages:

1. High Efficiency & Energy Saving
Oil-free operation with magnetic levitation bearings eliminates oil fouling that reduces heat exchange efficiency. The chiller maintains long-term high performance without degradation, reliably supporting continuous production requirements.

2. Intelligent Control
Equipped with a high-performance PLC intelligent control system, it achieves precise load regulation, adaptive energy savings, and remote monitoring – perfectly aligned with the digital project’s smart management needs.

3. Fast Start-up
Capable of fast start-up in just 20 seconds, it quickly resumes cooling after power outages or faults, minimizing shutdown risks and ensuring continuous system operation.

4. Low Inrush Current (as low as 25A)
Variable-frequency soft start reduces inrush current and grid impact. Low-frequency operation avoids frequent start/stop cycles, effectively reducing the project’s power consumption.

5. Advanced PID Fuzzy Algorithm
The motor supports wide-frequency regulation from 30 to 800 Hz and stepless capacity modulation from 10% to 100%. Water temperature control is faster and more stable, precisely matching the laboratory’s high-accuracy temperature control requirements.

The MULTISTACK JF MVW series magnetic levitation chiller, with its stable, efficient, and precise performance, perfectly fits the demanding application scenarios of China To***co Hunan, serving as a reliable “cooling heart” for the digital flavor blending project and helping the enterprise achieve simultaneous digital, intelligent, and green upgrades.

The successful implementation of this project marks the mature application of MULTISTACK JF’s fifth-generation magnetic levitation technology in high-end precision manufacturing and sets a new benchmark for precision cooling in the to***co industry. Moving forward, MULTISTACK JF will continue to leverage technological innovation to deliver efficient, stable, and green cooling solutions for more high-precision and digital-intelligent projects.

As a major cultural landmark in Hong Kong, the Hong Kong Museum of Art houses precious calligraphy, paintings, cultural relics, and contemporary artworks. It demands exceptionally high standards in environmental temperature stability, quiet operation, and long-term reliability. In January 2026, MULTISTACK’s MVSA series variable-frequency screw air-cooled chillers were successfully installed, delivering professional constant-temperature cooling for the venue.

This project is a retrofit. The chillers are installed on the museum’s rooftop, dedicated to providing stable temperature control for multiple exhibition halls and the premium collection storage area. A total of three MVSA units were deployed, successfully replacing the existing old units from a well-known brand. The chillers now operate smoothly, precisely meeting the stringent environmental standards required for collection preservation.

The Hong Kong Museum of Art ultimately chose MULTISTACK primarily for the units' precise temperature control, low-noise operation, easy installation, and long-term stability—characteristics that perfectly suit a museum’s need for quiet, uninterrupted operation. Leveraging advanced variable-frequency technology, the MVSA series chillers offer stepless capacity modulation from 20% to 100%, accurately matching the museum’s load fluctuations, achieving high energy efficiency, and significantly reducing electricity costs. Moreover, the solution was custom-tailored to the old system, enabling seamless integration and rapid replacement without affecting the museum’s normal operations.

Since commissioning, the MVSA chillers have consistently delivered stable cooling output with uniform temperature control that avoids fluctuations, effectively preventing temperature and humidity variations from damaging cultural relics and artworks. They provide round-the-clock protection for the artistic treasures and have received high recognition from the museum management.

With over 40 years of deep experience in the HVAC&R industry, MULTISTACK leverages its core magnetic-bearing and variable-frequency technologies to offer highly efficient, energy-saving, safe, and reliable cooling solutions for premium venues such as hotels, shopping malls, hospitals, and cultural institutions. The Hong Kong Museum of Art project once again confirms MULTISTACK’s professional strength in high-precision temperature control.

Looking ahead, MULTISTACK will continue to safeguard more cultural landmarks with high-quality products and mature technologies, providing stable, green, and intelligent temperature control for precious collections and high-end spaces.
