Calculation formulas for construction of cold storage for seafood preservation
- Calculate cold storage volume
Formula: V = E / gv (unit: m³)
- V: Cold storage volume
- E: Expected yield – amount of product that can be stored (tonnes)
- gv: Cold storage load standard (unit: tons/m³)
- Calculate total cold storage load area
Formula: F = V / h (unit: m²)
- F: Loading area (m²)
- V: Warehouse volume (m³)
- h: Cold storage loading height (unit m)
- Calculate warehouse foundation load
Formula: gf = gv xh
gf: Load rating (ton/m²)
- Calculate total cold storage construction area
Formula: FXD = F / βT (unit: m²)
- FXD: Area to be built (m²)
- F: Loading area
- βT: Coefficient taking into account the walking space area, gaps between products, and the installation area of the air conditioner, etc.

Structure and material selection for cold storage of seafoodn
Seafood cold storage has many advantages and is commonly used in Vietnam. Below is the main structure of cold storage, including 5 parts:
Cold storage shell
Cold storage shell made from Panel Insulation panels have common sizes of 800×1,200 mm and 1,000×2,000 mm. The panels are installed in continuous order, using specialized glue to form a solid block, blocking heat from the outside.
Cold storage door
Cold storage door Made of high-grade 340 stainless steel, with heat-resistant gaskets at the edge of the door to keep cold air inside and prevent air from entering. The door has a self-opening latch, alarm and anti-freeze heater.
Cold storage compressor
Compressor Compresses refrigerant from low to high pressure, removes vapor, and cools the system. Compressor selection is based on working pressure, air flow, power supply, environmental protection, installation type, noise level, and efficiency.
Cooling system
Refrigeration systems include direct and indirect cooling. Direct cooling uses an evaporator, while indirect cooling uses a refrigerant such as salt to reduce the temperature in the warehouse.
Control cabinet
The control cabinet controls and regulates the main operations of the cold storage. The parameters are pre-programmed, making it easy for users to use and ensuring the cold storage operates efficiently.

The best way to preserve seafood in cold storage
To preserve seafood in cold storage well, you need to know the following:
- Ensure warehouse temperature from -18°C to -20°C before preserving seafood.
- Maintain stable warehouse temperature at -20°C, product core temperature reaches -18°C or lower.
- Package carefully to avoid mixing seafood.
- For many types of seafood, carefully package each type.
- Arrange scientifically to ensure cold air circulation.
- Leave a minimum distance of 15cm between the floor and shelves, 50cm between the evaporator, ceiling, wall, and fan.
- Use the system to track and manage the arrangement and loading of goods.
Reasons to install cold storage for seafood preservation
Benefits of seafood cold storage
- Frozen storage does not require preservatives.
- Retains nutritional value and provides fresh products all year round.
- Avoid waste.
- Maintain supply of goods to the market.
- Reduce carbon footprint.
- Warehouse is easy to clean after shipment.
Applications of seafood cold storage
Long distance fishing: On-board freezing technology ensures the quality of the catch during long fishing days.
Preservation and transportation: Maintain fish quality from the fishing site to the distant consumption site, during processing and export, meeting the requirements of demanding partners.
Things to note when constructing seafood cold storage
Humidity
The humidity in the cold storage must be strictly controlled to avoid affecting the quality of the product. Humidity is closely related to the sublimation of ice in the product. Therefore, it is necessary to choose the appropriate humidity for each specific product to ensure the best preservation of the product.
Warehouse size
The size of the cold storage (Length x Width x Height) must depend on the specific needs of each business. For accurate information on the appropriate size, businesses should contact an expert for the most detailed and accurate advice.
Warehouse location
Enterprises need to measure and calculate the location of the cold storage to ensure convenience for transporting goods in and out of the warehouse. The cold storage should be designed near a power source and the floor must be flat to ensure efficient and safe operation.
Power supply
Businesses should use single-phase grid power for machines with a capacity of less than 5kW and three-phase grid power for machines with large capacity. For large cold storages, a separate grid power source is required to avoid phase deviation during peak hours, ensuring stable and continuous operation.
