The "SGL Elevator Room Non electric Refrigeration Solution" jointly developed by NAFUR&SGL Future Nanofunctional Materials Joint Technology Center has been officially launched. This solution is based on passive radiation cooling technology, achieving passive cooling and zero energy consumption operation, and combining AI intelligent monitoring and carbon accounting capabilities to provide a green temperature control new path for the renovation of old elevators.

1、 The problem of temperature control in elevator machine room remains to be solved

China has the largest number of elevators in the world. As of the end of 2024, the total number of elevators in use in China reached 11.5324 million, and approximately 130000 old elevators need to be updated or renovated each year.

In the daily operation of elevators, equipment rooms generally face the following prominent problems:

Summer high temperatures affect equipment stability

High energy consumption of air conditioning and high electricity bills

The control cabinet ages quickly and the failure rate increases

High operation and maintenance costs, uncontrollable data center environment

The traditional method of relying on air conditioning mechanical refrigeration not only has high energy consumption and complicated maintenance, but also poses safety hazards such as electric leakage and fire, making it difficult to meet the requirements of green buildings and dual carbon policies.

2、 Joint Technology Center: NAFUR&SGL Future Nanofunctional Materials Joint Technology Center

The NAFUR&SGL Future Nanofunctional Materials Joint Technology Center is committed to the research and application of nanofunctional materials in the field of energy conservation and carbon reduction. The center integrates NAFUR's cutting-edge research capabilities in the field of nanomaterials with the engineering experience of intelligent cooling in radiation cooling technology and scene implementation, focusing on:

Development and iteration of high-performance radiative cooling materials

Engineering application of nano functional materials

Scenario based implementation of green temperature control solutions

This joint technology center provides a solid technology research and development platform and continuous innovation capability for the solution of electric cooling in the intelligent cooling elevator machine room.

3、 Non electric cooling technology: a non power consuming cooling solution

Adopting passive radiation refrigeration technology, continuous cooling is achieved through two core material characteristics:

High solar reflectance (≥ 0.95): Reflecting most of the solar heat back

High infrared emissivity (≥ 0.94): Radiates heat directly into outer space through an atmospheric transparent window

This technology does not require electrical energy input, does not generate carbon emissions, and can effectively reduce the ambient temperature inside the equipment room. It is currently one of the few zero energy green material solutions in the field of energy-saving and temperature control in elevator machine rooms.

4、 AI Empowerment: Digitization from Materials to Management

The SGL elevator machine room non electric cooling solution is a complete digital temperature control system. By combining artificial intelligence technology, it is possible to achieve:

Intelligent monitoring: Real time perception of temperature and equipment status in the computer room

Engineering Quality Control: Visual Traceability of Construction Quality

Carbon asset accounting: Automatic conversion of energy savings into carbon emission reductions

Cluster management: Remote unified scheduling across multiple data centers

This shifts the temperature control of elevator machine rooms from passive response to active, intelligent, and quantifiable management closed-loop.

5、 Response policy: Support the construction of green supply chain

With the support of national large-scale equipment renewal and super long term special treasury bond funds, the process of upgrading old elevators has been accelerated. The zero energy consumption and zero emissions characteristics of the electric cooling solution for the intelligent cooling elevator machine room fully comply with the dual carbon goals, ESG governance, and green supply chain access requirements.

The plan has been formed:

Nanomaterials+AI algorithms+Lean engineering+ESG data services

The complete industrial form can help elevator and property enterprises enter the green supply chain directory and obtain policy and green financial support.

6、 Flexible deployment, quick implementation

The SGL elevator machine room non electric cooling solution can be tailored to the actual scenario of the customer, with efficient and environmentally friendly construction operations that do not require additional maintenance. At present, it has the ability to quickly replicate tens of thousands of units, which can meet the large-scale renovation needs of old elevators.

During the policy window period of elevator renovation, SGL's electric cooling solution for elevator machine rooms provides a low investment, zero carbon emission, and sustainable green temperature control solution for the elevator and property industries with the unique advantages of passive cooling, zero energy consumption, and digitalization.
