Energy Saving in Evaporative Coolers using Permanent Magnet Brushless Motors
Due to low cost, evaporative coolers are used in most of the central regions and in the warm and dry climate of Iran and are considered as one of the major consumers of electrical power. Most evaporative coolers use single-phase induction motors by connecting directly to the power grid. But their eefficiency is very low, and their replacement with high efficiency electric motors is considered b...
متن کاملSaving Energy in 1-D: Tailoring Energy-saving Advice Using a Rasch-based Energy Recommender System
Although there are numerous possibilities to save energy, conservation initiatives often do not tailor their content to the consumer. By considering energy conservation as a one-dimensional construct, where different behaviors have different execution difficulties, we have set out a Rasch-based energy recommender system that provides tailored conservation advice to its users. Through an online ...
متن کاملEnergy Saving Targets
A total factor energy saving target ratio (ESTR) for seventeen APEC economies over 1991-2000 is computed in this paper. All nominal terms are transformed into real terms at the 1995 price level. The data envelopment analysis (DEA) approach is used to find the energy-saving target (EST) for APEC economies without reducing their maximum potential GDPs. Energy, labor, and capital are the three inp...
متن کاملAlgorithms for Energy Saving
Energy has become a scarce and expensive resource. There is a growing awareness in society that energy saving is a critical issue. This paper surveys algorithmic solutions to reduce energy consumption in computing environments. We focus on the system and device level. More specifically, we study power-down mechanisms as well as dynamic speed scaling techniques in modern microprocessors.
متن کاملA review on recent applications of brushless DC electric machines and their potential in energy saving
Electric motors are the largest consumer of world electric energy, consuming more than twice as much as lighting, the next largest consumer. Electric motors account for between 43 and 46% of all global electricity consumption approximately. They give rise to about 6 040 Mt of CO2 emissions. End‐users approximately spend USD 565 billion per year on electricity [1]. In recent years...
