Considerations in Designing Cold Storage Rooms

22/11/2024

Certain parameters must be determined before constructing a cold storage facility. To ensure the system and equipment operate efficiently for many years without increasing energy consumption, these parameters must be accurately defined.

1- Determining the type of cold storage is essential, as it depends on the intended of the facility

    • Pre-Cooling Room: Used for pre-cooling products within a range of 0/+8°C.
    • Cold Storage Room (Cool Room): Used for cold storage within a range of +8/+14°C.
    • Cold Storage Room: Used for cold storage within a range of -1/+8°C.
    • Frozen Storage Room: Used for storing frozen products within a range of -18/-24°C.
    • Blast Freezing Room: Used for shock freezing within a range of -35/-45°C.

    2- Type of Products to Be Stored

    Each room in the storage facility should store only one type of product. However, if the products are in sealed packaging and have compatible storage temperatures, different products can be stored together..

    3- Storage Temperature and Relative Humidity of Products

    The design of the storage facility is calculated based on the type of products to be stored. Incorrectly chosen temperatures can lead to a shorter storage and shelf life of the products.

    4- Product Entry Temperatures

    The temperature at which products arrive at the storage facility is critical for determining cooling capacity.

    5- Daily Product Entry Volume

    Based on the volume of products entering the storage daily, requirements such as forklifts, workforce, truck parking areas, etc., are determined.



    6- Types of Product Packaging

    Depending on the storage type, products can be stored in cardboard boxes, crates, pallets, cases, or in bulk.

    7- Cold Storage Facility Dimensions

    The dimensions of the facility are determined based on the required capacity, available land, and zoning conditions.

    8- Number of Rooms in the Cold Storage Facility

    The number of rooms can be determined by the circulation speed and volume of products. If the rooms are too large, unloading will take a long time; if they are too small, the initial investment cost will increase.


    9- Geographical Conditions of the Cold Storage Location

    External weather conditions, relative humidity, and similar factors are crucial for accurately calculating the cooling load required for the products stored in the facility.

    10- Construction Type of the Cold Storage Facility

    The cold storage facility can be constructed as a reinforced concrete or steel structure. Insulation of the floor, walls, and ceiling is necessary to minimize heat gain.

    11- Cold Storage Door Types

    Doors in cold storage facilities are critical in preventing heat gain and controlling costs; therefore, the right door types should be selected.

  • Sliding Doors: Used for cold room doors. They should have sufficient width and height for forklifts to pass through.
  • Swing Doors: Used for transitions between operational and storage areas, as well as corridor access.
  • Sectional Doors: Used to separate processing or loading areas from external environments.
  • Expert in the Industrial Refrigeration System Industry.
