Project Overview: Preserving Beauty & Value for the Floriculture Industry
This project involved the design and construction of a sophisticated, multi-temperature cold storage facility in Chengdu, a major hub in China’s flourishing flower trade. The client, a leading floral distributor, required a specialized solution to overcome the critical challenge of extremely short vase life and high post-harvest loss rates for fresh-cut flowers and nursery stock.
The facility was engineered to provide three distinct climate zones, allowing for the optimal preservation of a wide variety of flowers at different stages of their lifecycle—from freshly cut blooms to dormant bulbs.
Technical Solution: Precision Climate Control Across Multiple Zones
The 5,000 cubic meter facility was segmented into eight independent chambers, each with tailored technology:
| Temperature Zone | Number of Chambers | Key Equipment Configuration | Insulation Specification |
|---|---|---|---|
| 0~8°C Fresh Flower Preservation | 4 | 1 x 60HP Copeland Scroll Quad Parallel Unit | 100mm Polyurethane Sandwich Panel |
| 12~18°C Constant Temperature for Fresh-Cuts | 1 | 1 x 15HP Copeland Scroll Unit | 100mm Polyurethane Sandwich Panel |
| -15~-20°C Flower Bulb Freezing | 3 | 2 x 30HP Frascold Piston Compressor Units | 150mm Polyurethane Sandwich Panel |
Core System Features:
- Refrigeration: Utilized Copeland scroll compressors for the medium/high-temperature zones (known for efficiency and low noise) and Frascold piston compressors for the low-temperature freeze zone (chosen for high capacity and reliability).
- Air Circulation: Each chamber is equipped with Zhejiang Kaili series high-efficiency air coolers to ensure rapid, uniform cooling and minimal temperature variance.
- Control & Monitoring: A Siemens fully automated control system provides centralized management, real-time monitoring, data logging, and remote alarms via mobile client, ensuring perfect conditions are maintained 24/7.
Tangible Results: Capacity, Timeline & Efficiency
This facility transformed the client’s operations by providing measurable, bottom-line benefits:
- Solved the Spoilage Problem: By stabilizing temperature and humidity, the cold storage dramatically slows flower respiration and ethylene production, extending marketable shelf life from days to weeks and reducing loss rates significantly.
- Maximized Storage Capacity & Flexibility: With 5,000 cubic meters of intelligently zoned space, the facility can store the equivalent of approximately 800 – 1,100 metric tons of floral products (using a standard industry volumetric conversion). The separate zones allow simultaneous storage of delicate fresh-cut flowers, blooming plants, and dormant bulbs.
- Achieved Rapid Deployment: The complete turnkey project, from design to commissioning, was completed within an efficient 60-day timeline, minimizing business disruption.
- Optimized for Energy Savings: The strategic design is key to controlling operational costs:
-
- The use of high-efficiency compressors and EC fan motors in the air coolers.
- Differentiated insulation thickness (150mm for freeze rooms) minimizes thermal loss.
- While exact kWh usage varies with load and ambient conditions, these features ensure the specific energy consumption (kWh per cubic meter stored) is optimized, leading to lower long-term electricity costs compared to less sophisticated systems.
