Cold Storage Cost Analysis
For example: Freezer Room Size: 5.2*3.5*4M ,Temperture:-25℃,380V/50HZ.
In the cold chain logistics, food processing, and catering industries, the cost of cold storage has always been a focus for customers.
A typical case is a 5.2×3.5×4 meter cold storage unit equipped with 150mm PU hook panels, a 5HP Emerson ZB38KQ refrigeration unit, and a design temperature of -15℃, with a quoted price of 3150USD.
This article will analyze the cost composition from three opinions: panels, Refrigeration equipment, and accessories.
1.Cold Storage Cost: The Thickness and Density of Polyurethane Insulation Panels are Key
The insulation performance of the cold storage directly determines the long-term energy consumption of the cold storage operation.
Taking this solution as an example, the panels use 150mm thick pu double-sided color steel panels with a density of 45kg/m³, and the surface layer is 0.5mm color steel panel.
Polyurethane has a low thermal conductivity (≤0.024W/(m·K)), which, combined with the hook plate structure, effectively reduces cold bridging and ensures airtightness.
The selection principles for polyurethane panel thickness under different temperature scenarios are as follows:
| Chiller Room | 0~5℃ | 75/100mm PU Panel | ||
| Freezer Room | -15℃ | 150mm PU Panel | ||
| Blasting Room | -35℃ | 200mm PU Panel |
The storage unit includes a floor panel and an 800×1800mm fully embedded door. While this customized design increases cost, it improves space utilization and loading/unloading efficiency.
This solution utilizes a 5HP Emerson Copeland ZB38KQ type compressor (380V/50Hz), a crucial component costing 3150USD.
Despite the lower price of domestically produced units, export-grade Copeland units possess three major advantages:
1. High efficiency and energy saving: Adopting a scroll design, they have high volumetric efficiency, significantly reducing long-term electricity costs;
2. Suitable for low-temperature environments down to -15℃, with a low failure rate and controllable maintenance costs;
3. Supports refrigerants such as R404A, conforming to international environmental trends.
Supporting components include liquid inlet/gas return pipes, insulation, valve components, and an electrical control box, ensuring system sealing and safety. Standardized configuration of lighting, wiring, and electrical components further enhances practicality.
Accessories and Services: Includes all accessories used in construction, such as valve welding and electrical equipment, avoiding additional expenses later.
Based on a storage capacity of 5.2×3.5×4 meters (approximately 72.8m³), the cost per cubic meter is approximately 65USD, which meets the industry standard for small and medium-sized cold storage facilities.
Cold storage construction costs are not simply a matter of price negotiation, but rather a balance between insulation performance, equipment quality, and long-term energy consumption.
The combination of 150mm polyurethane panels and Emerson Copeland compressor units, although with a slightly higher initial investment, can safeguard food storage with a lower failure rate and more stable temperature control.
For investors seeking long-term operational sustainability, this may be the answer to "value for money".
