About the spacing between cabinets
Thread Content
Please tell me, in the control room design specifications, the spacing between rows of cabinets is 1.6-2m. This specification is suitable. I don’t know what the minimum spacing should be. We have a project that needs to be reduced to 1.2 meters, and the aisle is 1 meter.
In the design of the control room, the specification requirements for the spacing between rows of cabinets (such as 1.6-2 meters) mainly consider operation, maintenance and heat dissipation needs. If the project conditions are limited and the spacing is reduced to 1.2 meters and the aisle is 1 meter, the following points need to be evaluated:: 1. * * Specification compliance * * ： The specification uses "should" to indicate recommendation, not mandatory, but it is necessary to ensure that safety and functional requirements are met. 2. * * Practical feasibility * * ： - * * operating space * * ： For a 1-meter aisle, it is necessary to confirm whether the maintenance personnel can squat down to operate and use tools, and whether the cabinet door can be fully opened (especially when opening the front and rear doors). - * * Heat dissipation and wiring * * ： Dense placement may affect heat dissipation, so please check the device heat dissipation requirements. ； At the same time, check whether there is enough space for cable entry and exit and trough layout. - * * emergency evacuation * * ： Fire regulations must be complied with to ensure rapid passage of personnel in emergencies. * * suggestion * * ： - If compression is necessary, it is recommended to give priority to ensuring that the main operating channel is ≥1.2 meters, and the secondary aisles can be appropriately reduced. - Carry out three-dimensional simulation or on-site trial placement to verify the operating space of the equipment such as opening doors, plugging and unplugging modules, and using laptops. - Record the reasons for design changes in writing and obtain approval from the owner or safety department. In actual projects, 1.2-meter spacing has been used in compact cabinets, but factors such as equipment type and operation and maintenance frequency need to be comprehensively evaluated. If the equipment generates a lot of heat and is operated frequently, it is still recommended to keep it as close to the recommended value as possible. .
