Tianjin Hangu Jinbin Wufu 4,000㎡ Fresh-keeping Cold Storage Project
Project Overview
Jinzhao Yuan Refrigeration designed and delivered a 4,000㎡ fresh-keeping cold storage facility for Jinbin Wufu in Hangu, Tianjin — a major domestic project serving the regional food distribution and fresh produce supply chain.
Project Background
Jinbin Wufu is a regional food distribution enterprise in the Tianjin Binhai New Area, supplying fresh fruits, vegetables, and aquatic products to supermarkets, restaurants, and community distribution networks across the greater Tianjin area. The project required a large-scale, multi-temperature fresh-keeping facility capable of handling diverse product categories while maintaining high energy efficiency and operational reliability.
Solution & Technical Highlights
- Storage Type: Fresh-keeping Cold Storage (multi-temperature zone)
- Total Area: 4,000 ㎡
- Temperature Zones:
- Fruit & Vegetable Zone: 0°C ~ +5°C, humidity ≥90%
- Aquatic Products Zone: -2°C ~ +2°C
- Pre-cooling Chamber: 0°C ~ +3°C (for rapid pre-cooling of incoming products)
- Refrigeration System: Screw parallel compressor units with variable frequency drive (VFD) for energy optimization
- Evaporators: High-humidity industrial cold air fans with anti-drip design, minimizing produce dehydration
- Insulation: 150mm PU panels with food-grade white steel inner finish
- Doors: Insulated automatic sliding doors with high-speed PVC rapid roll-up doors at dock interfaces
- Drainage: Fully sealed floor drainage system with sanitary-grade slope design
- Control: Centralized BMS (Building Management System) integration with energy monitoring and alarm management
Results
- Fresh produce storage capacity: 2,000 metric tons
- Pre-cooling efficiency: incoming product temperature reduced from ambient to target storage temperature within 4 hours
- Overall energy consumption 22% lower than previous conventional refrigeration system
- Cold storage availability rate: 99.5%+, supporting 365-day continuous operation
