Moteur StirlingLe moteur Stirling est un moteur à combustion externe et à fluide de travail en cycle fermé. Le fluide est un gaz soumis à un cycle comprenant quatre phases : chauffage isochore (à volume constant), détente isotherme (à température constante), refroidissement isochore, enfin compression isotherme. Robert Stirling a inventé en 1816 le moteur à air chaud et, pour améliorer son efficacité, l'a muni d'un régénérateur, qui assure une fonction de stockage thermique et d'échangeur interne.
Cycle de Rankine400px|thumb|Diagramme entropique du cycle de Rankine avec l'eau comme fluide de travail Le cycle de Rankine est un cycle thermodynamique endoréversible qui comprend deux isobares et deux adiabatiques. C'est le cycle qui se rapproche le plus du cycle de Carnot. Il se distingue de ce dernier par la substitution de deux transformations isobares aux deux transformations isothermes, ce qui rend possible sa réalisation technique. Il fut inventé par William John Macquorn Rankine (1820-1872) qui lui donna son nom.
SuperchargerIn an internal combustion engine, a supercharger compresses the intake gas, forcing more air into the engine in order to produce more power for a given displacement. The current categorisation is that a supercharger is a form of forced induction that is mechanically powered (usually by a belt from the engine's crankshaft), as opposed to a turbocharger, which is powered by the kinetic energy of the exhaust gases. However, up until the mid-20th century, a turbocharger was called a "turbosupercharger" and was considered a type of supercharger.
Stirling cycleThe Stirling cycle is a thermodynamic cycle that describes the general class of Stirling devices. This includes the original Stirling engine that was invented, developed and patented in 1816 by Robert Stirling with help from his brother, an engineer. The ideal Otto and Diesel cycles are not totally reversible because they involve heat transfer through a finite temperature difference during the irreversible isochoric/isobaric heat-addition and heat-rejection processes.
Fan coil unitA fan coil unit (FCU), also known as a Vertical Fan Coil-Unit (VFC), is a device consisting of a heat exchanger (coil) and a fan. FCUs are commonly used in HVAC systems of residential, commercial, and industrial buildings that use ducted split air conditioning or with central plant cooling. FCUs are typically connected to ductwork and a thermostat to regulate the temperature of one or more spaces and to assist the main air handling unit for each space if used with chillers.
