Design of Cold Storage Panel

Cold storage panel is an important material for building cold storage. Thermal stability defines the long-term performance of large cold storage facilities. Panel modularization and precise joint sealing directly influence insulation efficiency, construction speed, and operational energy consumption.

Modular Design of Cold Storage Panel

In large-scale cold storage construction, modular cold storage panel design plays a decisive role in improving project efficiency and reducing lifecycle cost. Harbin Dongan Building Sheets Co., Ltd. operates as an intelligent manufacturer of prefabricated energy-saving building materials. With rich project experience and ISO 9001 quality management certification, the company has developed mature technical solutions for large cold storage enclosure systems.

Standardized modular coordination forms the core of its design strategy. Cold storage panels follow a unified modulus system that allows flexible combination in length, width, and height. Thickness options range from 50 mm to 200 mm to meet different temperature requirements, while the standard width of 1000 mm supports efficient batch production and rapid on-site assembly. Supported by more than 30 specialized production lines, the company delivers over 2 million square meters of panels annually, which ensures supply capacity for large-volume projects.

Modularization significantly accelerates installation progress. Construction teams can improve on-site assembly efficiency by more than three times compared with traditional custom fabrication methods. The system also supports future expansion or relocation of the cold storage facility. Developers can disassemble and reinstall panel units without major structural modification, which enhances long-term asset flexibility. This adaptability aligns with the development trend of prefabricated cold storage buildings and reduces overall capital risk.

Advanced Sealing Design

While modularization improves efficiency, joint sealing determines insulation performance. Connection quality of cold storage panel directly affects air tightness, vapor control, and the prevention of thermal bridging. The company applies a concave–convex interlocking joint structure that enhances mechanical engagement and improves seam stability. Combined with a double sealing system that meets industry standards, the linear thermal bridge coefficient remains below 0.035 W/(m·K), which helps maintain stable internal temperatures.

Installation procedures further strengthen insulation integrity. Technicians apply sealant within transverse tongue-and-groove joints before compression fastening. Longitudinal connections reserve a minimum 20 mm gap, which installers fill with polyurethane foam before applying auxiliary sealing components. This method eliminates internal cavities and prevents air leakage. During bolt fastening, workers add steel washers and rubber gaskets to improve tightening force and vapor resistance. These measures effectively reduce condensation risk and minimize cold bridge formation.

Material performance also contributes to energy efficiency. The polyurethane sandwich panels offer thermal conductivity as low as 0.018–0.024 W/m·K. Core density remains controlled between 40–42 kg/m³, and the closed-cell ratio reaches at least 95 percent. These parameters support stable low-temperature storage in large facilities. The panels integrate seamlessly with the company’s steel structure systems through coordinated 3D modeling services, ensuring dimensional precision between enclosure panels and the primary frame.

Compatibility with R290 environmentally friendly refrigerant systems further enhances energy performance. When combined with modular enclosure design, the overall energy efficiency ratio of the cold storage facility can increase by more than 8 percent. Annual comprehensive energy consumption declines accordingly, supporting carbon reduction goals and sustainable building standards.

Stable long-term operation in large cold storage projects depends on efficient modular design and reliable joint sealing. Through standardized production, precise sealing technology, and integrated structural coordination, Harbin Dongan Building Sheets Co., Ltd. delivers durable, energy-efficient, and economically optimized solutions for modern cold storage facilities.
