Cycle frigorifiqueLe cycle frigorifique est un cycle thermodynamique. Il permet d'abaisser la température d'un milieu relativement froid (la source froide) et simultanément d'augmenter la température d'un autre milieu relativement chaud (la source chaude) au moyen d'une dépense d'énergie mécanique. Il est notamment utilisé dans les réfrigérateurs ou les pompes à chaleur.
Dynamic demand (electric power)Dynamic Demand is the name of a semi-passive technology to support demand response by adjusting the load demand on an electrical power grid. It is also the name of an independent not-for-profit organization in the UK supported by a charitable grant from the Esmée Fairbairn Foundation, dedicated to promoting this technology. The concept is that by monitoring the frequency of the power grid, as well as their own controls, intermittent domestic and industrial loads switch themselves on/off at optimal moments to balance the overall grid load with generation, reducing critical power mismatches.
Mechanical, electrical, and plumbingMechanical, electrical and plumbing (MEP) refers to the installation of services which provide a comfortable space for the building occupants. In residential and commercial buildings, these elements are often designed by a specialized MEP engineering firms. The part of Mechanical in the overall MEP system is almost 70% of the total work. MEP's design is important for planning, decision-making, accurate documentation, performance- and cost-estimation, construction, and operating/maintaining the resulting facilities.
Hot air engineA hot air engine (historically called an air engine or caloric engine) is any heat engine that uses the expansion and contraction of air under the influence of a temperature change to convert thermal energy into mechanical work. These engines may be based on a number of thermodynamic cycles encompassing both open cycle devices such as those of Sir George Cayley and John Ericsson and the closed cycle engine of Robert Stirling. Hot air engines are distinct from the better known internal combustion based engine and steam engine.
BioélectromagnétismeLe est la production de champs électriques, magnétiques ou électromagnétiques par les cellules, les tissus ou les organismes vivants. Le potentiel de membrane des cellules et les potentiels d'action propagés par les fibres nerveuses sont des exemples du bioélectromagnétisme. Les cellules des organismes vivants font usage de la bioélectricité pour stocker de l'énergie issue du métabolisme, pour produire un travail ou pour transmettre des signaux à d'autres cellules.
Poêle (chauffage)Un poêle (prononciation ou ) est un appareil de chauffage comprenant une chambre de combustion pour du bois ou du charbon. Généralement utilisé pour le chauffage direct par rayonnement thermique et/ou par convection, le poêle peut aussi permettre de produire de l'eau chaude. Par métonymie, le poêle désignait aussi la pièce chauffée d'une habitation. upright|Poêle à bois moderne dit « poêle bouilleur » (producteur d'eau chaude).
List of stovesThis is a list of stoves. A stove is an enclosed space in which fuel is burned to provide heating, either to heat the space in which the stove is situated, or to heat the stove itself and items placed on it. Stoves are generally used for cooking and heating purposes. Aprovecho – Aprovecho Research Center has worked on designs for cook stoves, primarily for use in developing countries. They are best known for the Rocket stove, developed by their technical director Dr. Larry Winiarski.
