Recently, the Ministry of Industry and Information Technology and other four departments jointly issued the “Energy-saving Equipment High-quality Development Implementation Plan (2026-2028)”, “radiation refrigeration materials” was clearly listed as “industrial refrigeration (heat) equipment” in the field of cutting-edge key technologies to be tackled. This indicates that this passive cooling technology, once regarded as “black technology”, has officially entered the fast lane of national industrialization.
Behind the policy, it confirms a fast-growing technology track. Industry analysis shows that the global radiation refrigeration materials market is expected to be close to 30 billion billion yuan, with a compound annual growth rate of more than 13%. The technology is expected to “open a new era of zero-carbon cooling” and become one of the basic technologies for green transformation in the fields of construction, energy, and agriculture. This is not only in response to national research, but also the layout of a deterministic industrial future.
Principle Diagram
What is radiation refrigeration (also known as radiation refrigeration)?
It is a passive cooling technology with zero energy consumption and no moving parts. The core is to make the material “open source and throttle” in a specific wave band:
“throttle”: have high reflectivity (>90%) to sunlight (wavelength 350-2500nm)
“open source”: have high infrared emissivity (>93%) in the atmospheric transparent window (8-13μm) wave band, and dissipate heat to outer space in the form of radiation.
The two work together to reduce the surface temperature of the cabinet by 15-25°C and save 20-60% of energy consumption.
Scenario Focus
exactly what the market needs. This technology is especially suitable for temperature-sensitive and energy-intensive facilities:
Electric energy storage systems: Battery life and safety are extremely dependent on operating temperature.
The radiation cooling coating can cool the energy storage cabinet from the outside, reduce the energy consumption of the cooling system, and improve the safety and full life cycle benefits.
granary and cold chain storage: granary storage is prone to heat and mildew, and energy consumption is huge to maintain a low temperature environment.
The coating is applied to the exterior walls and roofs of buildings, which can reduce the heat from the source of solar radiation, passively reduce the surface temperature, and reduce the internal cooling load. It is an important means of energy saving and efficiency.
green ice has been applied in energy storage, granary and other scenes. the reliability and great energy saving potential of this cutting-edge technology have been verified by actual effects. What we provide is not only a new material, but also a “zero energy consumption cooling” solution for specific scenarios to achieve cost reduction and safety improvement.
