Record 2 2003-11-06

English

Subject field(s)
  • Thermodynamics
  • Heating
DEF

... the result of air’s lower density at elevated temperatures and its affinity to rise. Cooler air sinks due to the increase in density.

OBS

Convection. Process of heat [(transfer of heat) ] carried from one point to another by movement of a liquid or a gas(i. e., air). Natural convection is caused by expansion of the liquid or gas when heated. Expansion reduces the density of the medium, causing it to rise above the cooler, more dense portions of the medium. Gravity heating systems are examples of the profitable use of natural convection. The air, heated by the furnace, becomes less dense(consequently lighter) and rises, distributing heat to the various areas of the house without any type of blower. When a blower is used, the heat transfer method is called "forced convection. "

French

Domaine(s)
  • Thermodynamique
  • Chauffage
CONT

Dans la convection libre (ou naturelle), le mouvement est dû à la seule action de la pesanteur, lorsque des différences de masse volumique provenant de différences de température rompent l'équilibre hydrostatique.

OBS

La convection, qui est un mouvement ascendant et descendant des molécules d'un fluide subissant un réchauffement, est l'un des trois phénomènes de la transmission de la chaleur entre deux corps (ou fluides) à températures différentes.

Record 4 1999-10-28

English

Subject field(s)
  • Ovens, Furnaces and Boilers (Heating)
DEF

A furnace equipped with a fan that provides the primary means for the circulation of air.

CONT

Warm air furnaces are of two types, gravity and forced air. Forced warm air furnaces use a motor-driven blower to circulate air over the heat exchanger and through the ducts. A draft hood is attached to the outlet of the furnace and replaces the barometric damper.

OBS

Forced-warm-air furnaces are most commonly fired by LP gas, natural gas or oil and occasionally by wood and coal. They may also operate electrically.

French

Domaine(s)
  • Fours et chaudières (Chauffage)
DEF

Générateur d'air chaud doté d'un ventilateur qui constitue le moyen principal de circulation de l'air.

CONT

Générateurs d'air pulsé. (...) ces générateurs sont constitués des éléments suivants : -un caisson d'aspiration (...) -un ventilateur centrifuge (...) -un corps de chauffe (...) -un bloc de distribution à plusieurs bouches; -une sortie de fumée avec modérateur de tirage. L'ensemble est enfermé dans un habillage calorifugé en acier laqué; il est complété par un organe de régulation qui commande la marche du ventilateur en fonction de la température de l'air.

OBS

Dans le système de chauffage à air pulsé, la circulation d'air est assurée par un ventilateur électrique (...) Ce système permet de placer la fournaise n'importe où et d'utiliser des conduits plus étroits et plus longs.

OBS

Fournaise : Ce terme est considéré comme impropre par les puristes. Selon Dagenais, dans son "Dictionnaire des difficultés de la langue française au Canada", "fournaise" serait un calque de l'anglais "furnace" et nous devrions plutôt dire "chaudière" lorsque le fluide caloporteur est l'eau ou la vapeur et "générateur d'air chaud", lorsque le fluide, est l'air. Cependant, ce terme reste d'usage fréquent au Québec, autant en langue parlée qu'en langue écrite.

Subject field(s)
  • Heating
CONT

Warm-air heating system. Strictly speaking, however, a warm-air system is one containing a direct-fired furnace surrounded by a bonnet through which air circulates to be heated.... A completely equipped furnace-blower package consists of furnace, burner, bonnet, blower, filter and accessories.

Key term(s)

French

Domaine(s)
  • Chauffage
CONT

Les installations à air chaud. [...] le fluide utilisé pour le transport de la chaleur est l'air. Cet air est distribué dans les locaux desservis [soit directement, soit indirectement] dont il réchauffe l'atmosphère par mélange. L'air peut être pulsé ou non; il peut aussi recevoir un traitement particulier (humidification, séchage, ozonisation). Il est traité dans des appareils spéciaux (échangeurs), dans lesquels il augmente sa température au contact de surfaces de chauffe qui sont soit alimentées par un fluide auxiliaire (eau, vapeur ou électricité) s'il s'agit d'aérothermes, soit léchées directement sur la face opposée par les gaz de combustion provenant d'un foyer propre à l'appareil dans le cas des générateurs. Les installations à air chaud peuvent donc être subdivisées: soit en chauffages à air chaud à circulation naturelle ou en chauffages à air chaud pulsé; soit en chauffages par aérothermes ou en chauffages par générateurs à foyer indépendants.

Such furnaces may be used in closets and utility rooms on the first floor of homes or in basements with the return air ducted down to the blower compartment entrance.

CONT

The three basic types [of forced air furnace] are upflow, counter flow and horizontal, and there are several variations depending on the actual installation.... The highboy (upflow) furnace is used primarily in single-level homes when the ducts are placed in the attic. This may be because of the slab on grade construction or because there is limited crawl space. The furnace may be located in a closet or recessed area in the wall. The air enters the furnace through a low side entry or through the bottom, and it leaves through the top.

OBS

Among the principal types [of forced-air furnaces] used for residences and small buildings the following arrangements are common: ... High-boy arrangement with up-flow of air, in which the blower is located at the bottom of the casing and the heat exchanger is located at the top.... High-boy arrangement with down-flow of air, in which the blower is located at the top of the casing and the heat exchanger is located below the blower.

CONT

The horizontal furnace has the blower located beside the heat exchanger with the air entering one end, traveling horizontally through the blower and over the heat exchanger and discharging out the opposite end. Such furnaces are used for locations with limited head room, such as attics or crawl spaces below floors or suspended under the ceiling.

Forced Air Wood Furnaces. Central wood-burning furnaces are controlled by a wall mounted thermostat in the living area. Temperature and fan controls are the same as those found on oil and gas furnaces. Unlike room heaters, which produce a steady heat output by periodic manual adjustments of the draft control, most wood furnaces operate in cycles. A cycle starts with the thermostat sensing that heat is needed in the room where it is located. It signals the furnace control system which opens the combustion air damper and a hot fire develops. When the air inside the furnace's sheet metal casing gets hot, a preset fan control starts the circulating blower and the warm air is moved through the ducts to all areas of the house.
