Recently, Chuanleng Technology's power-free refrigeration technology has been applied to two major projects, respectively in Jiangsu Changzhou Hongchuan Petrochemical and Hang Lung Properties, two leading enterprises in their industries. The technology covers temperature control for storage tanks and energy conservation in buildings, with a total area exceeding 5,000 square meters. At Hongchuan Petrochemical, the power-free refrigeration technology enhances the temperature control of benzene storage tanks day and night, reducing the risk of evaporation caused by temperature fluctuations. At Hang Lung Plaza, the roof temperature was measured to have dropped by 36°C, significantly reducing the load on the air conditioning system. As a new green technology, power-free refrigeration is increasingly recognized by leading enterprises in various industries as a preferred solution for cooling, energy conservation, and green transformation.
Hongchuan Benzene Storage Tanks - 2160㎡ Chemical Project Cooling Renovation
Hongchuan Group is a leading enterprise in the chemical warehousing market, with its tank capacity accounting for 10% of the entire chemical warehousing market. Jiangsu Changzhou Hongchuan Petrochemical Storage, as a member of Hongchuan Group, focuses on chemical warehousing as its core business, specializing in the storage and transportation of liquid chemical products. It has extremely high requirements for temperature control and needs to maintain a stable temperature for a long time.
Temperature control challenge for benzene tanks: overheating leads to explosion, overcooling causes solidification
The tanks where the adiabatic cooling technology was applied in Hongchuan Petrochemical, Changzhou, Jiangsu Province mainly store benzene chemicals, which are highly dependent on stable temperature control: overheating can lead to explosion, overcooling causes solidification, and large temperature fluctuations may cause abnormal pressure inside the tanks, posing storage and transportation risks.
The temperature difference between day and night in spring and summer at the project site can reach up to 21°C. Although traditional aluminum silicate insulation boards have heat insulation effects, their cooling capacity is limited, and they have long construction periods and high costs.
Coating area: 2160㎡, temperature difference reduced to within 5°C
- Coating area: 2160㎡
- Temperature control performance: The average temperature difference between day and night in the experimental storage tank was only 3.9°C, far lower than the nearly 10°C temperature fluctuation inside the tank before coating.
- Technical comparison: The cooling effect is comparable to that of a 100mm silica-alumina insulation board, with more convenient construction and lower overall cost.
Reducing Emissions and Storage Risks
The power-free refrigeration technology effectively reduces the frequency of the "small breathing effect" of storage tanks, decreases the volatilization of benzene and other substances, and alleviates the fatigue of tank structures, thereby enhancing operational stability and equipment lifespan. It has the capability to replace traditional insulation materials in high-safety-level working conditions.
Wuxi Henglong Plaza - 3000㎡ Application, Temperature Reduction Up to 36°C
Wuxi Henglong Plaza is a flagship commercial complex in the city's core area, developed and operated by Hang Lung Properties, a global top commercial real estate operator. It has extremely high standards for the energy efficiency, appearance quality, and brand image of the building.
Last year, the project piloted the application of the power-free cooling coating in the roof area on the sixth floor, and the actual test results were remarkable. This year, the project further expanded the application scope, covering the entire roof area of approximately 3000㎡, comprehensively promoting green upgrades.
The average temperature of the roof before coating was 53.6℃. The roof of Wuxi Henglong Plaza is composed of aluminum plates and concrete, which have strong thermal conductivity. Combined with the heat from the kitchen and the impact of the west sun, the local temperature in summer can reach over 53.6°C, making it a major energy consumption point of the entire building.
- Maximum cooling amplitude: 36°C
- Annual electricity savings: estimated to reach 220,000 kWh
- Annual electricity cost savings: over 100,000 yuan
The advantages of zero interference and short construction period
The project verified the actual cooling effect of the non-electric cooling coating in a high-temperature composite environment, significantly reducing the burden on air conditioning. During construction, normal business operations were not affected, with a short period and minimal disruption, making it suitable for commercial places with high requirements for operational continuity.
Boosting Energy Efficiency Transformation in Industries - More Stable for Chemicals, More Economical for Commercial Use
From chemical storage tanks to commercial rooftops, the performance of Chongleng Technology's electricity-free refrigeration technology in terms of safety, energy efficiency, and adaptability has been highly recognized by leading enterprises in multiple industries, demonstrating the potential for large-scale application of the technology.
In the future, Chongleng Technology will continue to expand the practical application boundaries of electricity-free refrigeration technology in more industries, using material innovation to serve the low-carbon transformation of cities and industries.
