Hasta hace poco, hablar sobre ahorro energético y eficiencia parecía estar reservado a los amantes de la naturaleza. En la actualidad se ha convertido en algo imprescindible y no solo desde un punto de vista comercial: también surge de las directivas y regulaciones aprobadas por gobiernos de todo el mundo, que tratan de reducir el impacto del cambio climático. En el sector industrial más del 70% de la energía utilizada se destina al funcionamiento de motores eléctricos. Dentro de pocos años, todos los motores eléctricos deberán garantizar un rendimiento superior al exigido en años anteriores y este proceso de optimización se verá potenciado por el uso de convertidores de frecuencia. Perfectamente adaptados El secreto oculto tras el espíritu vacacional mediterráneo del centro comercial de Bremerhaven reside en sus avanzados sistemas de ventilación. La temperatura se mantiene en niveles agradables gracias a los ventiladores controlados por convertidores VLT® de Danfoss, que aseguran un intercambio óptimo del aire además de reducir la factura energética. El Centro Comercial Mediterraneo está equipado con 18 unidades de tratamiento del aire, divididas en cuatro grupos para suministrar el Until very recently, to talk about energy saving and efficiency seemed to be the preserve of nature lovers. Today, it has turned into a critical element and this is not only from a commercial standpoint: it is also contained in the directives and regulations passed by governments worldwide, in their efforts to reduce the impact of climate change. In the industrial sector, more than 70% of energy utilised is dedicated to driving electric motors.Within a few years, every electric motor must guarantee a level of efficiency higher than that required in the past and this optimisation process will be enhanced by the use of frequency converters. Perfectly adapted The hidden secret behind the Mediterranean holiday spirit of the Bremehaven shopping centre lies in its advanced ventilation systems. The temperature is kept at pleasant levels thanks to the fans controlled by VLT® converters from Danfoss, which guarantee an optimal exchange of air in addition to reducing the energy bill. The Mediterraneo Shopping Centre is equipped with 18 air handling units, divided into four groups to supply the cleanest air and ensure a temperate climate inside the building. A central control system gathers data in real time and transmits the necessary references to the frequency converter by means of a BACNet interface. The 36 VLT® HVAC Drive FC 102 converters from Danfoss with IP55 guarantee reliable and problem-free operation in the ventilation section of the system. This high level of protection facilitates simple, fast installation. Along with the AHUs, the VLT® HVAC converters from Danfoss power the two compressors in the heat pumping system to guarantee optimal efficiency, significantly reducing both consumption and energy costs, as well as operational costs. Greater energy efficiency can be obtained by adjusting the speed of the heat pumps to achieve an optimal operational level so that the system uses no more energy than necessary. What sets the VLT® from Danfoss apart is its simple and intuitive operation. The screen displays a menu with fast adjustment functions, ideal for installation in applications that are typical in the construction sector. Moreover, the screen copy function of the LCP enables fast communication of data between similar devices and a backup copy of all information. In the event of error, a backup converter comes into operation in simple mode. All necessary parameters UN CENTRO COMERCIAL EN EL NORTE DE EUROPA COMBINA A LA PERFECCIÓN UN AMBIENTE DE COMPRAS Y UN AHORRO ENERGÉTICO DE HASTA EL 50% En el renovado distrito del puerto de Bremerhaven, una ciudad alemana situada en la costa del Mar del Norte, el Centro Comercial Mediterraneo ofrece a habitantes y turistas la oportunidad de relajarse en un agradable entorno mediterráneo. ¿Qué hace que el aire sea tan especial?
