Improved energy efficiency thanks to consistent digitization

[4789] A study performed by control cabinet and air conditioning specialist Rittal showed that many installed cooling solutions are overdimensioned.

On the other hand, devices installed in the control cabinets are often placed incorrectly, leading to hot spots. Based on these findings, Eplan, Phoenix Contact, and Rittal worked out concepts for bringing more efficiency to control cabinet construction planning, documentation, and to facilitate optimal design and climate control. These concepts moreover help to ensure compliance with DIN EN 61439, which defines the proper planning and documentation of control cabinets.

Phoenix Contact will present the solution at SPS IPC Drives 2015 as part of the ‘consistently digital’ focus area, which is demonstrated in Hall 9 at Booth 310 based on the ‘Smart Engineering and Production (SEAP)’ use case. The company already provides relevant device data – including maximum power loss, minimum clearances, or directions of flow in the case of self-ventilation – for many of its components on the Eplan Data Portal. For this purpose, thermal information is transferred in BMEcat format with eCl@ss classifications. Once the planner has completed virtual setup of the control cabinet and defined the positions of all devices to be installed, the Eplan Pro Panel engineering tool indicates the distribution of the component’s power loss in relation to their installation volume or surface area. This allows for detecting hot spots at a glance. If an active cooling system is required, customers can readily select a suitably dimensioned device and all accessories. Consistent digitization of product data thus goes a long way towards empowering customers to implement energy-efficient control cabinets.
