Suzhou Taicang Yuanxi Food Co., Ltd. 80,000m³ Low-Temperature Food Processing and Cold Storage Project

Project Overview

Project Location: No.169 Damuqiao Road, Shaxi Town, Taicang City, Suzhou, Jiangsu Province, China
Contract Date: June 2022
Construction Period: 150 days
Total Volume: 80,000 m³

This large-scale food processing and low-temperature cold storage logistics project was designed and built by haocool Refrigeration for Suzhou Taicang Yuanxi Food Co., Ltd., a well-known regional enterprise specializing in frozen meat and prepared food products.

The project consists of two high-standard double-story cold warehouses with a total storage volume of 80,000 cubic meters. The cold storage is designed as a multi-temperature variable cold room divided into six temperature zones ranging from +10°C, 0~4°C, and -18°C, suitable for different stages of food processing, freezing, and storage.

Customer Challenge

Before construction, Yuanxi Food faced major operational constraints:

• Insufficient cold storage capacity, forcing reliance on third-party warehousing.
• High operating costs from outdated refrigeration systems and logistics inefficiency.
• Unstable product quality due to temperature fluctuations in rented facilities.

They needed a centralized, energy-efficient cold chain facility to integrate processing, storage, and distribution while reducing long-term energy and logistics costs.

Engineering Solutions

1. Structural & Insulation System

• Floor insulation: High-density extruded polystyrene (XPS) boards with waterproof treatment.
• Underfloor heating: Full underfloor pipeline network to prevent frost heave and maintain stable temperatures.
• Warehouse panels: B1-grade fire-retardant cold storage panels ensuring optimal insulation performance.

2. Advanced CO₂ Cascade Refrigeration System

• 2 high-temperature compressor units
• 2 medium-temperature units
• 2 CO₂ compressor sets
• 4 evaporative condensers
• 2 CO₂ condensers
• 2 CO₂ charging stations
• 2 CO₂ circulation tanks (medium & low temp)
• 4 heat recovery exchangers (for floor heating and hot water reuse)
• 4 water defrost pumps + 1 defrosting tank
• Complete PLC automatic control and monitoring system for temperature and humidity management.

3. Electrical & Control System

• Full LED lighting system throughout warehouse and corridors.
• Dedicated power wiring for sliding doors, loading docks, forklifts, and monitoring.
• Integrated CO₂ gas detection & alarm, humidity and temperature sensors, and remote data monitoring.

Project Performance

• Construction Duration: 150 days from design to commissioning.
• Storage Capacity: Approx. 8,000 tons of frozen and chilled food products.
• Temperature Zones: 0~4°C (chilled), -18°C (frozen), 10°C (processing & staging area).
• Refrigeration Type: CO₂ cascade system with variable temperature control.
• Energy Savings: Reduced electricity consumption by 25% compared with conventional ammonia systems.
• Operational Stability: Maintains precise temperature ±0.5°C and humidity ±3% across all zones.

Customer Benefits

After project completion, Yuanxi Food successfully:

• ✅ Integrated production, storage, and logistics into a single facility, improving efficiency by 40%.
• ✅ Cut annual energy consumption by nearly one-quarter through advanced CO₂ refrigeration and heat recovery.
• ✅ Increased total storage capacity from 3,000 tons to 8,000 tons.
• ✅ Enhanced product quality and reduced spoilage loss by 30%.
• ✅ Reduced third-party cold storage rental costs, achieving payback within three years.

The new 80,000m³ facility now serves as a benchmark low-temperature food processing logistics center in East China, combining high performance, low emissions, and cost-effective operation.
