Project Overview: From Regional Hub to Integrated Cold Chain Powerhouse
This project was the critical cold storage component within the Phase II development of the Zhejiang Southwest Bulk Material Import, Warehouse & Distribution Trading Center. The overarching goal was to transform the center from a logistics hub into a comprehensive agricultural product deep-processing base. Spanning a massive total construction area of approximately 270,000㎡, the base is designed to attract and house processing businesses for local specialties like tea, fruits, mushrooms, vegetables, and herbal products.
The cold storage facility was engineered to be the backbone of this expansion, providing the essential temperature-controlled infrastructure to support large-scale processing, extend shelf-life, and enable regional distribution of value-added agricultural goods.
Core Specifications & Performance Metrics
| Item | Specification / Metric |
|---|---|
| Total Cold Storage Volume | Approximately 15,000 Cubic Meters |
| Total Cold Storage Area | ~ 5,163 Square Meters (across five chambers) |
| Design Temperature | -18°C (0°F) for all chambers |
| Estimated Storage Capacity | Capable of storing ~3,000 – 3,500 Metric Tons of frozen or deep-frozen processed goods. |
| Primary Energy-Saving Feature | Evaporative Condensers with Variable Frequency Drive (VFD) fans for significant water and power savings. |
| Key Advantage | Five Independent Refrigeration Systems (one per chamber) ensure operational redundancy and flexible utility management. |
Solving the Client’s Strategic Challenges
1. Problem: Lack of Scale & Modern Infrastructure for Value-Added Processing.
- Solution Provided: This large-scale, centralized cold storage facility provided the essential “plug-and-play” infrastructure that individual processing tenants could rely on. It eliminated their need for massive capital investment in private cold storage, making the entire deep-processing base a more attractive and viable destination for businesses.
2. Problem: Need for Reliable, High-Capacity Frozen Storage for Processed Goods.
- Solution Provided: With a capacity for thousands of tons of goods, the facility guarantees that processed items like frozen fruit pulps, tea extracts, or herbal concentrates can be stored safely in bulk. This enables tenants to process in large batches during harvest seasons and sell their products gradually throughout the year, stabilizing supply chains and improving market pricing power.
3. Problem: Managing Operational Costs and Energy Efficiency at Scale.
- Solution Provided: The design directly targeted high energy efficiency, a major long-term cost driver.
- Efficient Hardware: The use of Hanbell screw compressor parallel units offers high efficiency at low-temperature conditions.
- Smart System: The evaporative condensers with VFD fans adjust cooling output based on real-time load and ambient conditions, avoiding the constant high energy draw of traditional air-cooled condensers. This leads to substantially lower electricity consumption per ton of cargo stored.
Technical Configuration for Reliability & Efficiency
- Refrigeration Systems: Five (5) independent systems were installed, each serving one cold storage chamber. Each system consists of:
- Compressor: Two Hanbell semi-hermetic screw compressors in parallel (2 x 95.6KW cooling capacity).
- Condenser: One giant evaporative condenser (700KW heat exchange capacity) per system, featuring fully automatic control and VFD fan motors.
- Cooling Distribution: Each chamber is equipped with eight (8) single-side air discharge ceiling-mounted air coolers (22.3KW each), ensuring rapid pulldown and even temperature distribution for stored products.
