“…As a consequence, OEMs, which are mainly interested in a motor's list price since they do not pay for operating costs, do not consider them a good choice [8]. In any event, the production phase of SRM motors must be improved in order to reduce first costs; one clear disadvantage is the large amount of magnetic steel waste generated from punching.…”

Abstract. This paper compares the environmental and life cycle impact of one switched reluctance motor (SRM) drive and two inverter-fed induction motor (IM) drives. The study was carried out according to the Directive on the Ecodesign of Energy-Using Products (EuP 2005/32/EC) and following the Methodology for the Ecodesign of Energy-Using Products (MEEUP). The following base-case models were used: an IM (Eff3), an IM (Eff1) and an 8/6 SRM. All of these base-case models are rated at 1.5 kW of output power and are considered to be representative of the low-power range. The analysis shows that SRM drive has a lower environmental impact than the IM drives and offers a high savings potential, comparable to, or even greater than that of the IM (Eff1) in the use phase.

“…1 Although a widely-used concept, barriers to improvements in energy efficiency are classified in multiple and overlapping ways (Blumstein et al, 1980;Painuly and Reddy, 1996;Sorrell et al, 2000 andde Almeida et al, 2003;. On a scale where a barrier is at one end a fact, and at the other, a construct of the actors in a sector, it is likely that these barriers will fall somewhere in between at varying levels.…”

The objective of this research is to empirically examine the drivers and barriers to energy efficiency measures in an important energy-using sector, namely the food retail sector, and support more effective energy efficiency policies for this sector. Although food retailers consume a significant amount of energy due to the refrigeration, air conditioning and specialised lighting needs of stores, there has been little research in this sector on the barriers and drivers for implementing energy efficiency measures. A survey of small food retailers was carried out to understand the barriers and drivers to greater uptake of energy efficiency measures and to examine the acceptability of different energy efficiency policy options for food retailers. In addition, external stakeholders were consulted in order to validate and contextualise the results of the survey. We find there is a complementary relationship between energy efficiency barriers and drivers for food retailers that is remarkably coherent. We identify policies, such as subsidies and support for ESCOs, that both exploit the complementarities between barriers and drivers and are acceptable to food retailers also. This methodology should help identify and design more effective policies to deliver energy efficiency improvements in the food retail sector.

“…Nowadays, the energy efficiency of these systems has become more important as the political and ecological pressure to reduce energy consumption is increasing (European Parliament 2009). In variable-flow fluid handling systems, the use of rotational speed control instead of throttle control has shown to improve the system energy efficiency, and many studies make a strong argument to increase the number of frequency converters, often called simply variable speed drives (VSDs) in fluid handling systems (de Almeida et al 2005;European Parliament 2009;de Almeida et al 2003;Binder 2008). …”

Abstract-Fluid handling systems such as pump and fan systems are found to have a significant potential for energy efficiency improvements. To deliver the energy saving potential, there is a need for easily implementable methods to monitor the system output. This is because information is needed to identify inefficient operation of the fluid handling system and to control the output of the pumping system according to process needs.Model-based pump or fan monitoring methods implemented in variable speed drives have proven to be able to give information on the system output without additional metering; however, the current model-based methods may not be usable or sufficiently accurate in the whole operation range of the fluid handling device. To apply model-based system monitoring in a wider selection of systems and to improve the accuracy of the monitoring, this paper proposes a new method for pump and fan output monitoring with variable-speed drives. The method uses a combination of already known operating point estimation methods. Laboratory measurements are used to verify the benefits and applicability of the improved estimation method, and the new method is compared with five previously introduced model-based estimation methods. According to the laboratory measurements, the new estimation method is the most accurate and reliable of the model-based estimation methods.
