Operation Explained.

The development by the General
Electric Co. of q new direct-fired warm
air conditioner especially designed for
the small house and priced to place
Winter air conditioning within the
reach of the small home owner has
just been announced by J. ]. Donovan,
manager of the air conditioning de-
partment. 1t will be placed on the
market Immediately, the announce
ment said.
Air conditioning has but recently
started to make definite progress In
the residential field, and its greatest
use to date has been in commercial
applications for profit. With the wide
appeal 1t has made to the general
public, which Is now accustomed to
its benefits in stores, theaters, hotels
and such applications, it has for some
time been obvious that air condition
ing would eventually Supplant other
forms Of heating and would be en-
bodied in all new home construction.
That frequently forecast progress has
definitely started during the past year.
but has been largely confined to
higher priced homes. The advance
of air conditioning in smaller and
moderately priced homes is expected
to materialize more swiftly with this
new development which assures the
small home owner of the benefits of
conditioned air and economical oil
heating at price within his reach.
Battle of Air and Oil.
The new product, designed for the
home Of about six rooms, combines
in one compact oil-burning unit all
the functions of heating and Winter
air conditioning. The now well-estab-
nshed principle Of impact-expansion
atomization announced three years
ago when General Electric introduced
its oil furnace, and until now featured
exclusively In that furnace, is incor-
porated in the new warm air condt-
toner. The principle embodies a
veritable battle between streams OF
air and oil, to break the oil into a
complete mist, thus effecting COM
plete combustion of the lower grade
fuel oils which have the greatest heat
content. Also the flame burns down.
ward, ard the fiue is at the bottom,
providing the most efficient utilization
OF heat and eliminating the possibil-
ity Of wasted heat, according to the
companys technical description.
The new unit is the only air con-
ditioner to embody these heating
principles. It will also contain filters,
to clean the air; humidifler. to sup
ply the proper amount of moisture;
blower, to induce proper circulation,
and all other equipment necessary for
Winter air conditioning The supply
of air for the house Is drawn into the
conditioner by the action of the
blower, filtered, heated by direct con-
tact with the furnace, humidified and
then delivered to the rooms of the
house by duct system.
Cleaned Air Circulated.
The new warm air conditioner has
a heat rating of $4,000 B. T. U. per
hour, and will deliver and properly
circulate approximately 1880 cubic
feet a minute of cleaned, hunidifled,
tempered air. Not less than a gallon
OF water per hour will be used to give
adequate humidification in cold
weather. A hot water supply heating
coil and also a cooling unit will be
available for use with the new unit.
An attractive rolled sheet steel
Jacket of two-tone gray, with black
and chromium trim, will house the
unit, which occupies but 2 feet 9
inches by feet inches Of floor space
and stands S feet inches high.
Being both compact and attractive, 1t
gives the home owner the benefit Of
added space. allowing him to convert
the saved basement space into game
room or lounge. 1t is described as
quiet, clean and free from vibration,
and is automatically regulated by
electrically operated controls.
The combination of all equipment
in one unit will effect economies in
both installation and operating costs
in the small house field, In which there
Is now considerable building activity.
For larger houses, separate furnaces
and air conditioning units will be
used, as before, the company an
stated. In this method,
the air Is heated indirectly, by means
of heating coils in the conditioner,
connected to the furnace.
