Description

Technical Field

[0001] The utility model belongs to the technical field of modular expandable box-type refrigeration stations, and in particular relates to a prefabricated modular expandable box-type refrigeration station. Background Art

[0002] The traditional cold station construction method is to transport the chillers, circulating water pumps, cooling towers and other equipment in the cold station to the project site after selection, procurement, factory processing and other links, and then hoist them into place on site, followed by a series of processes such as pipe cutting, assembly, welding and connection of pipes and equipment interfaces, and finally installation and commissioning. This construction method has a large proportion of on-site work, many cross-operations of multiple trades and professions, high construction difficulty and on-site coordination workload, and a long and difficult-to-control construction period, which also increases the safety risks of on-site workers.

[0003] Traditional cold stations are not designed and planned before construction, and the layout of equipment and pipelines is unreasonable, resulting in repeated dismantling and modification during the construction process, making it impossible to achieve one-step installation, resulting in serious waste of manpower and material resources, and causing serious waste of internal space;

[0004] When the cold station is installed on-site using the traditional method, there are many parts to be assembled on-site. Not only is it easy to make mistakes when assembling, but the quality of the pure manual method is also low. In the later installation process, the technical level of the operators is affected, resulting in poor visual effects of the finished product and cumulative errors, which affects the debugging efficiency and increases the workload of later operation and maintenance.

[0005] During the trial operation and routine maintenance of the container cold station after installation, the chiller and other equipment modules need to be drained. The conventional practice is to lay a separate drainage (drainage) pipeline during the installation phase, or to use drainage ditches on the bottom plate of the container, which takes up internal space and increases construction costs.

[0006] Conventional container refrigeration stations do not set limit devices for the equipment after it is in place inside the container. It is only fixed by its own weight. It is very easy for the equipment to have a large displacement due to its own vibration during operation, causing damage to other system components and the entire system, affecting the normal operation of the system;

[0007] For conventional container refrigeration stations, the cooling tower is heavy and only relies on the container roof as support. The overall stability of the refrigeration station is poor, and it is very easy for the cooling tower to overturn or become unstable during operation.

[0008] When conventional cold station projects are designed and implemented, their designed cooling capacity, usage scenarios and design requirements will be limited. When the owner's needs change in the later stage or the project needs to be upgraded such as renovation and expansion, it cannot be expanded and needs to be rebuilt, which increases the project development cost and engineering cycle, and cannot flexibly meet the owner's cooling needs;

[0009] In order to solve the above problems, the present application proposes a prefabricated modular expandable box-type cold station. Utility Model Content
