Key Scenario Characteristics:
1. Frequent door openings
2. Frequent forklift traffic
3. Large temperature fluctuations
Project Pain Points：
1. Severe cooling loss. A large amount of cooling capacity is lost every time the door is opened. Due to the large internal space, temperature recovery is relatively slow.
2. Energy consumption significantly exceeds design expectations. High-frequency operation increases system load, often resulting in excessive refrigeration energy consumption.
3. Condensation and frost buildup around door areas. Frequent door opening causes rapid temperature fluctuations near the entrance, making condensation and frosting more likely, which can affect both safety and equipment operation.
Targeted Solutions for Project Challenges
The core of the optimization and design lies in maintaining system stability under high-frequency disturbances, rather than simply focusing on thermal insulation.
The airtightness of a cold storage enclosure system depends not only on the insulation performance of the panels themselves, but also on joint structure, sealing treatment, and installation quality.
PU and PIR insulated panels are commonly used in cold storage applications due to their low thermal conductivity, which can reach as low as 0.019–0.024 W/m·K, providing excellent thermal insulation performance. Rock wool panels are more often applied in areas with higher fire-resistance requirements.
Cold storage panels typically adopt interlocking or cam-lock joint designs, offering strong airtightness, reliable connections, and efficient installation.
2.Integrate Door Areas Into The Overall Cold Storage Enclosure System Design.
By combining cold storage doors with insulated foam cores into the enclosure system through an integrated sealing design, cooling loss can be effectively reduced.
3. Reduce Thermal Bridging and Condensation Risks Through Optimized Joint Design
Condensation on cold storage interior surfaces is often related to thermal bridging and insufficient joint airtightness. To reduce these risks, optimized detailing is required at critical connection areas, including:
Wall-to-roof connections — affecting overall airtightness and thermal bridge control
Wall-to-floor connections — impacting insulation continuity and long-term operational stability
Door frame areas — directly influencing cold air leakage and condensation risks
Corner joints — related to structural sealing performance and stress changes
Therefore, in practical projects, attention is given not only to panel performance itself, but also to the continuity of the entire enclosure system through optimized joint and connection detailing.
4.Condensation Control Strategy for Logistics Cold Storage
While ante-room (airlock) design reduces direct air exchange, it does not fully eliminate condensation risks. Effective control requires an integrated approach combining humidity control, airflow management, and thermal optimization:
(1) Humidity control: desiccant dehumidification systems applied in ante-room areas to maintain low dew-point air and reduce moisture ingress into cold zones.
(2) Airflow and pressure management: controlled air movement and slight positive pressure design to limit humid air infiltration during frequent door operations.
(3) Ante-room (airlock) configuration: dedicated buffer zones to reduce temperature shock and direct air exchange between ambient and refrigerated spaces.
(4) Thermal bridge optimization: prevention of localized cold spots at door frames and structural junctions to minimize condensation and frost formation.
