Project Overview
The project consists of nine individual cold rooms designed for different storage needs:
- 7 Fresh-Keeping Rooms (0°C to +5°C), Total Volume: 7,700 m³
- 1 Pre-Cooling Room (0°C to +5°C), Volume: 1,100 m³
- 1 Blast Freezer (-30°C), Volume: 1,050 m³
Refrigeration System Configuration
Fresh-Keeping Rooms (0°C~+5°C)
- Equipped with a Hanzhong RC2-100B three-parallel screw compressor unit
- 7 units of Kaidi DL260 high-efficiency ceiling air coolers
Pre-Cooling Room
- Two sets of RefComp SP4H2500 piston compressors
- 2 units of Kaidi DL260 air coolers
Blast Freezer (-30°C)
- One Hanzhong LB-180 screw compressor
- 2 units of Kaidi DJ170 high-static blast freezer evaporators
Insulation & Construction Materials
- Fresh-keeping & pre-cooling rooms: 100 mm polyurethane sandwich panels (B1 fire rating)
- Blast freezer: 200 mm polyurethane panels (B1 fire rating)
Temperature Control & Monitoring System
The project uses a Siemens fully automatic control system featuring:
- Remote monitoring
- Mobile APP control
- Audit-trail recording
- Door-switch monitoring
- SMS alert system
- Automatic defrosting
- Automated backup-unit switching based on return-air temperature
This ensures precise temperature stability for agricultural produce and reduces energy waste.
What Problems Did This Project Solve for the Client?
1. Insufficient Storage → Expanded to 10,000 m³
The market can now store over 2,000 tons of produce, solving seasonal overflow issues.
2. High Spoilage Rate → Controlled at 0°C to +5°C
Fresh fruits and vegetables now maintain stable moisture and freshness during long-term storage.
3. No Pre-Cooling Capability → Added 1,100 m³ Pre-Cooling Room
Pre-cooling reduces respiration heat and extends shelf life, lowering losses by 15%–20%.
4. Lack of Deep Freezing → Added -30°C Blast Freezer
Products requiring deep freezing can now be processed on-site, eliminating outsourcing costs.
5. Manual Management → Centralized Digital Control
The Siemens control system significantly reduces labor costs and improves reliability.
Project Timeline
- Design: 12 days
- Manufacturing & material delivery: 25 days
- On-site installation: 60 days
- Commissioning & training: 8 days
👉 Total project duration: ~105 days
Energy Consumption
Based on full-load operation:
- Fresh-keeping rooms: 32–40 kWh per 100 m³ per day
- Pre-cooling room: 45–55 kWh per 100 m³ per day
- Blast freezer: 85–110 kWh per 100 m³ per day
Average operating cost for the entire 10,000 m³ facility:
👉 Approximately USD 210–260 per day (depending on product load & ambient temperature)
Storage Capacity
With typical stacking density:
- Total Capacity: ~2,000–2,300 tons of fruits, vegetables, and frozen products
