General Technical Requirements and Usage Configuration for Containerized Mobile Cold Storage Units
1Key Takeaways
This document stipulates the general technical requirements, other purpose technical requirements, and usage configuration requirements for containerized mobile cold storage units. This document applies to the selection and use of containerized mobile cold storage units.
2Expert Interpretation
Professional interpretation of WB/T 1143-2024 containerized mobile cold storage standard, covering core technical requirements such as storage materials, refrigeration systems, temperature control, etc., comparing and analyzing the differences between mechanical and cold storage solutions, and providing structural strength and airtightness implementation plan recommendations in transportation scenarios.
Analysis of the core content of the standard
WB/T 1143-2024 systematically standardizes the technical system of container-type mobile cold storage for the first time, raising the standardization level of cold chain logistics equipment to a new height. This standard innovatively integrates container technology and refrigeration technology, and proposes a "modular + mobile" cold chain solution.
Comparison of key technical indicators
| Technical dimension | Mechanical refrigeration | Cold storage refrigeration | Test standard |
|---|---|---|---|
| Temperature accuracy | ±1℃ | ±2℃ | 4.2.2.4 |
| Defrosting requirements | Forced automatic defrosting | No requirement | 4.3.1 |
| Transport heat leakage rate | ≤5m³/h | ≤3m³/h | 5.4a |
Innovation requirements for warehouse materials
Article 4.1.3 of the standard clearly requires the use of three-proof and one-blocking (anti-corrosion/anti-moth/moisture-proof/flame-retardant) composite materials, and the inner wall must comply with the GB4806.1 food contact safety standard. The density index of polyurethane insulation materials has been increased to 40kg/m³ (Article 5.5c), which is 33% higher than that of traditional cold storage.
Actual application case
After a fresh food e-commerce company adopted cold storage container mobile cold storage, the energy consumption in the transfer link was reduced by 27%. Its corner columns are made of ASTM A588 weathering steel (Article 5.5a), which remains maintenance-free for 8 years in the high salt fog environment of the coast.
Special Specifications for Transportation Scenarios
Chapter 5 proposes dynamic strength indicators for transportation conditions: longitudinal 2g, lateral 1g, vertical 2g acceleration (Table 1), structural strength ≥300MPa. The charging interface must comply with the GB/T20234.3 DC standard and be equipped with aviation waterproof connectors (Clause 6.3.4).
Implementation Suggestions
- Preferably use modular design to meet the GB/T39661 exchange box standard
- The temperature control system needs to integrate ±1℃ sensors and sound and light alarm devices
- The transportation configuration needs to simultaneously consider the compatibility of the lifting equipment and the special trailer
