Record 1 2010-09-27

English

Subject field(s)
  • HVAC Distribution Systems
  • Heating
DEF

Radiators, convectors, baseboards, finned tubing, coils embedded in floor, wall, or ceiling, or any device which transmits the heat from the heating system to the room and its occupants.

CONT

Heat emitters in central heating systems may be classified in two broad groups: primarily convective and primarily radiant.

CONT

Radiators, convectors, and baseboard and finned tube units are types of heat-distributing devices commonly used in steam and low temperature water heating systems. They supply heat through a combination of radiation and convection, and their function is to maintain the desired air temperature in the space. In general, these types of heat-distributing units should be placed at the points of greatest heat loss of the space to offset or counteract these losses. For example, such units are commonly located under windows, along exposed walls, and at door openings.

OBS

heater: something that heats: a contrivance that imparts heat or holds something to be heated: as a stove, furnace, radiator, or other device for giving off heat.

French

Domaine(s)
  • Distribution et évacuation (chauffage et conditionnement d'air)
  • Chauffage
DEF

Partie d'un appareil producteur de chaleur, [utilisé en chauffage central,] dans laquelle une énergie chimique ou électrique est transformée en énergie calorifique [...] [Exemples :] tubes lisses, tuyaux à ailettes, convecteurs, radiateurs [...]

DEF

[...] appareils destinés à transmettre dans les locaux la chaleur produite par les générateurs [...] différents [types] [...] employés en chauffage central [:] Radiateurs [...] Tuyaux lisses [...] Tuyaux à ailettes [...] convecteurs [...]

CONT

Une installation de chauffage dit "central" comporte, en outre : un réseau de distribution [...] des émetteurs de chaleur qui, au niveau du local à chauffer, cèdent à ce local la chaleur dont il a besoin.

CONT

Les corps de chauffe (radiateurs ou convecteurs) sont souvent disposés en allège des fenêtres.

Record 2 1999-03-22

English

Subject field(s)
  • Electrical Convertors
  • Energy Transformation
DEF

A device in which heat energy is directly converted to electric energy; it has two electrodes, one of which is raised to a sufficiently high temperature to become a thermionic electronic emitter, while the other, serving as an electron collector, is operated at a significantly low temperature.

French

Domaine(s)
  • Convertisseurs (Électrotechnique)
  • Transformation de l'énergie
CONT

Un convertisseur thermo-ionique comprend deux électrodes, l'émetteur porté à haute température [...] et le collecteur [...]. Les électrons libérés par l'émetteur migrent vers le collecteur où ils abandonnent une fraction de leur énergie, la fraction restante leur permettant de circuler dans la charge extérieure.

Key term(s)
  • cellule thermoionique
