Common Cold Storage Project Design Approaches
As a company specializing in the design and construction of cold storage projects, we frequently work with a wide variety of clients. Regarding the design and construction of conventional cold storage projects, cold chain logistics warehouses are primarily used for storing foods such as fruits, vegetables, meat, and frozen products. Small and medium-sized cold storages typically have capacities ranging from 1,000 to 5,000 tons. Generally, a single steel structure building can meet this tonnage requirement. It is commonly estimated that one ton of goods occupies about 5 cubic meters (fruits and vegetables about 5 cubic meters, frozen products about 4 cubic meters per ton). The height of the cold storage is usually between 6 to 8 meters, which allows for the storage of 3 to 4 levels of shelving. For a 5,000-ton project, the floor area is approximately 4,500 to 5,500 square meters, with a height between 6 to 8 meters. The cold storage can be divided into areas of different sizes. Considering the various types of goods to be stored, different rooms are created for ease of future management and equipment use.
The width of the platform receiving and dispatching area is generally about 6-8 meters, which is suitable. The receiving and dispatching area is typically equipped with functions such as a management office, equipment room, changing room, tool room, forklift charging area, temporary storage area, cold storage rooms, and others. Based on common functional zoning, we have prepared the following design drawings for customer reference.
Proposal 1: Platform Area in Length Scheme
This design scheme has the receiving and dispatching area along the longer side, with the platform placed in the length direction. In this case, the cold storage width is generally within 20-30 meters, which is suitable for efficient operation times, preventing long delays for forklifts when entering and exiting the warehouse. The design is conducive to smooth operations and convenient management of goods entering and exiting. All vehicles are parked at the long-side platform area for receiving and dispatching goods. The building's orientation avoids direct sunlight during afternoon working hours. Depending on the local sunlight conditions, the platform area can be placed on the east side, as the morning sun is not intense. This way, during afternoon and mid-afternoon operations, the sunlight will shine from the side, rather than directly onto the platform area, effectively saving energy.
A 5,000-ton cold storage can be divided into 6-8 rooms, with each room having a capacity of about 600-800 tons. In the future, it can be considered for rent or self-use. Depending on the actual business needs, the number of rooms can be adjusted. Alternatively, the cold storage can be divided into 10 rooms, each with a capacity of 500 tons. The entire building can use a single steel structure with rock wool insulation panels for maintenance. Inside the steel structure, cold storage insulation panels are used, and refrigeration equipment consists of screw-type parallel compressor units with evaporative condensers. The refrigerant used is the environmentally friendly R507. Cold air units are used inside the cold storage, and the control system is managed by a PLC control system. The defrosting method uses hot fluorine defrosting.
This refrigeration technology scheme, for a 5,000-ton cold storage project, includes a civil foundation work duration of about 1 month, steel structure construction time of about 2 months, cold storage construction period of about 3 months, and operation commissioning, cooling, and training time of about half a month. The total construction period for the entire project is about 6 months.
The equipment manufacturing time is about 1 month. The power supply required for the 5,000-ton cold storage is about 300-350 kW, 380-415V/3P.
Proposal 2: Platform Area in Width Scheme
This design scheme places the receiving and dispatching area along the width direction, with a central passageway, making it convenient for the management of goods entering and exiting the cold storage. The receiving and dispatching area can also include functions for goods processing and sorting before entering the storage. This design approach is also a good choice. The area of the receiving and dispatching zone can be adjusted according to the required storage capacity, typically ranging from 500 to 800 square meters, allowing for functions such as processing, sorting, and temporary storage.
Proposal 3: L-shaped Building Design
This cold storage planning design can be constructed in an L-shaped structure based on the actual land conditions. It is also a good design option. It facilitates the management of receiving and dispatching goods, with the L-shape allowing for proper allocation of parking space and equipment areas according to the actual site dimensions. In practical applications, this design scheme is also commonly used.
Regardless of the chosen design scheme, it is important to consider the actual land conditions on-site, the location of the main entrance, and the parking area. The design should facilitate future truck access and operations, as convenience for practical use is the key consideration. It is also necessary to account for future expansion plans, such as reserving space for a potential second phase of the project.
Above are several design approaches we have compared for common cold storage solutions.
