— Thematic Academic Conference on AI and HVAC Industry Development by the Hunan Provincial HVAC & Refrigeration Professional Committee, 2025

[Changsha · Wisdom Valley Energy Station] On November 22, 2025, the "AI and HVAC Industry Development Technical Exchange Conference," jointly organized by the HVAC & Refrigeration Academic Committee of the Hunan Provincial Civil Engineering and Architecture Society and MULTISTACK Jiefeng Group, was successfully held at the World Computing · Changsha Wisdom Valley Smart Energy Station. As an annual exchange platform in the HVAC field of Hunan, the conference gathered over 200 industry experts, university scholars, and enterprise representatives. Centering on the "Wisdom Valley Energy Station" as a core case study, participants jointly explored low-carbon development pathways for the industry through the integration of AI technology and magnetic levitation applications.

[Technical Dialogue: Two-Way Sharing of In-Depth Cultivation and Practical Application]

During the morning thematic presentations, MULTISTACK Jiefeng Group delivered a speech titled "Three Decades of Cultivation in Magnetic Levitation Technology and Breakthroughs in Application Scenarios." It outlined MULTISTACK Jiefeng's journey from pioneering the development of the world's first magnetic levitation centrifugal compressor and leading the adoption of this technology in the refrigeration industry, to implementing benchmark projects like the high-efficiency magnetic levitation refrigeration plant in Hunan. The focus was on technology implementation and project effectiveness.

Subsequently, the Hunan Provincial Architectural Design Institute presented the "Design Sharing of Changsha Wisdom Valley Energy Station and Xiangya Hospital Energy Station." Addressing the practical needs of these major healthcare and campus scenarios, it analyzed the integrated application logic of MULTISTACK Jiefeng's MTW-F series magnetic levitation chillers and AI algorithms. It is precisely this system synergy that enabled the Wisdom Valley Energy Station to achieve outstanding performance metrics, such as a cooling energy efficiency ratio (EER) of 6.0 and a heating coefficient of performance (COP) of 5.35, providing a reference design paradigm for the industry.

[On-Site Visit: The Practical Application of Magnetic Levitation Units]

During the equipment room tour, attendees entered the core area of the Wisdom Valley Energy Station for a close-up view of the MULTISTACK Jiefeng MTW1000FH magnetic levitation ground-source heat pump unit. Feng Xiangyu, Sales Director of MULTISTACK Jiefeng, introduced on-site that this model is currently the world's largest single-unit capacity magnetic levitation ground-source heat pump. Designed for a heating capacity of 1000RT, it achieves an annual comprehensive energy-saving rate exceeding 50% in operation.

[Analysis of the Core Performance Advantages of the MTW-FH Series]

The practical features of the MULTISTACK Jiefeng MTW-F series have been fully validated in projects, with prominent core advantages:
High Efficiency and Energy Savings: Integrates technologies like magnetic levitation compressors for source-level consumption control and stable energy efficiency.

Intelligent Regulation: Equipped with a peer-level microcomputer core and intelligent cloud services for dynamic optimization strategies and improved operational and maintenance efficiency.

Reliable Redundancy: Features a multi-compressor sharing design that controls costs while ensuring stability; a single unit failure does not affect energy supply.

Low Noise and Vibration: Magnetic levitation technology enables frictionless operation, with noise levels as low as 73dB, making it suitable for sensitive environments like hospitals.

Forum at Wisdom Valley, grounded in practice. In this exchange, MULTISTACK Jiefeng, anchored by solid technical practices, joined hands with industry peers to explore new pathways for low-carbon development in HVAC. Looking ahead, MULTISTACK Jiefeng will continue to deepen the scenario-based innovation and optimization of magnetic levitation technology, delivering HVAC solutions that combine energy efficiency and reliability for more industry projects.
