UPFLOW FURNACE [8 records]

Record 1 1990-01-08

English

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

Furnace in which the circulating air flows upward, discharging at or near the top of the casing.

CONT

The upflow or high-boy furnace has the blower beneath the heat exchanger discharging vertically upward. Air enters through the bottom or the side of the blower compartment and leaves at the top. 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.

OBS

Furnaces for forced air systems are available in various designs.... In addition, each is usually classified in terms of the direction in which the air is delivered. The three basic types are upflow, counter flow and horizontal, and there are several variations depending on the actual installation.

Key term(s)
  • up flow furnace
  • up flow forced warm air furnace
  • up draft furnace

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

Les modèles proposés, pour les plus nombreux, sont verticaux (...) Les figures 9A et 9B montrent respectivement un générateur vertical et un horizontal.

OBS

Il existe trois modèles principaux d'appareil de chauffage électrique à air pulsé pour les différents types de construction. Le système à circulation ascendante est semblable aux appareils de chauffage classique au mazout ou au gaz, l'air chaud étant distribué depuis le dessus de l'appareil dans les conduits de distribution, et le retour de l'air de la maison se faisant à l'arrière ou sur le dessus de l'appareil. C'est celui qui convient le mieux pour les sous-sols.

Record 2 1990-01-08

English

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

Furnace through which the circulating air flows in the opposite direction to the flue gases.

CONT

Basically, there are three types of gas furnaces. They are : the upflow; the counterflow; and the horizontal furnace. The direction of air flow through the furnace is the determining factor for its name.

OBS

Le rendement des appareils [de chauffage à air chaud] ne semble pas affecté par la forme lamellaire ou tubulaire des échangeurs, mais les échangeurs à contre-courant, comme il est normal, conduisent à un meilleur rendement de la surface d'échange que les échangeurs à courants parallèles ou croisés.

The upflow or high-boy furnace has the blower beneath the heat exchanger discharging vertically upward. Air enters through the bottom or the side of the blower compartment and leaves at the top. 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.

Record 4 1990-01-08

English

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

Low-boy arrangement with furnace and blower in separate compartments, and with air discharged upwards. Used for basement installation, but also usable with furnace closets located on the first story.

CONT

The basement or low-boy furnace is a variation of the upflow furnace and requires less head room. The blower is located beside the heat exchanger at the bottom. The air enters the top of the cabinet, is drawn down through the blower and discharged over the heat exchanger, and leaves vertically at the top.

Subject field(s)

CONT

Oil furnaces. Indoor oil furnaces... are available in upflow, downflow, horizontal and low-boy configurations for ducted systems. They are also available as floor furnaces, wall furnaces, and free standing space heaters. Oil-fired outdoor furnaces and combination units are rare.... The ducted system, oil-fired, forced air furnaces are usually equipped with pressure-atomizing burners. The pump pressure and the orifice size of the injection nozzle regulate the firing rate of the furnace. Electric ignition is used to ignite the burners.... The combustion chamber and heat exchanger of oil-fired furnaces are normally formed as a common single chamber. It is formed from heavy gage steel into a welded assembly. The hot flue products flow through the inside of the heat exchanger into the chimney. The conditioned air flows over the outside of the heat exchanger and into the air supply plenum.

Maison de fin de semaine (...) On peut prévoir aussi le chauffage par air chaud avec générateur à mazout ou à gaz et distributions par gaines.

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.
