Key Scenario Characteristics:

1. Designed for long-term stable operation with minimal frequent access

2. High requirements for temperature uniformity and hygienic conditions

3. Commonly used in food processing and storage enterprises

Project Pain Points：

1. Temperature fluctuations caused by local temperature differences and uneven cooling distribution often lead to unstable product quality.

2. Condensation inside the cold storage, especially on wall surfaces and joint areas, can affect hygiene and create structural risks for long-term operation.

3. Cold air leakage through panel joints and mismatched insulation systems can result in increasing energy consumption year by year.

Targeted Solutions for Project Challenges

The core optimization focus lies in improving the airtightness and insulation continuity of the enclosure system to maintain stable cold storage operation.

1. Improve Enclosure Airtightness to Reduce Cold Air Leakage and Temperature Fluctuation

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. Flexible Panel Thickness Selection for Different Temperature Zones

Cold storage panel systems are available in thicknesses ranging from 50 mm to 250 mm, allowing solutions to be tailored according to different temperature zones, operational requirements, and insulation targets.

This enables precise adaptation for refrigerated areas, frozen storage zones, and other specialized cold-chain environments.

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.
