"COMBUSTIBLE-GAS FED STORAGE SYSTEM FOR THE PRODUCTION OF
HOT WATER FOR HOUSEHOLD USE"
Abstract Combustible-gas fed storage system for the production of hot water for household use, wherein a toroidal-chamber regenerative compressor sucks the combustion air from the outside through a first small-diameter pipe, and expels the flue gases to the outside, through another small-diameter pipe coaxially positioned inside said first small-diameter pipe.

Abstract Combustible-gas fed storage system for the production of hot water for household use, wherein a toroidal-chamber regenerative compressor sucks the combustion air from the outside through a first small-diameter pipe, and expels the flue gases to the outside, through another small-diameter pipe coaxially positioned inside said first small-diameter pipe.
Description
GAS-FIRED WATER~EATI-NG SXSTEM
The present invention relates -to a gas-fired water-heatlng ~ystem ~or producing hot water, whlch system can advanta~ou~ly be used in bathroom~ wherein the possibility does not exist o~ ins~alling a hood for exhausting ~lue gas.
It i~ known that the present trend is to replace electrical power with a ch~ap~r energy sourae. This need is ~elt, above all, in the ~ield of water heater~, wherein the saving in cost attainted by heating water with combusti~le gas rather than with electrical power is considera~le.
Unfortunately, when installing gas-~ired water-heating systems, provision has to be made ~or exhausting the flue gas.
In modern bathrooms, or in other rooms where the installation of a gas-fired water heating system is envisaged, an exhaust hood is generally provided, and that maXes i~ easy to produce hot water by using a combustible gas. ~owever, in mo~t bathrooms, i.e.
those in older buildings, an exhaust hood i9 not provided, and therefore the instal.lation of a gas-ired water-heating system would require the use of large-diameter pipes for conveying the flue gases to the outside, and, consequently/ the ~ormation o~ holes through the walls, which are generally main walls, such holes being hence. not eas~ to form, or even being prohibited.
The object of the present invention is to overcome the above drawbacks and to provide a gas-fired water~
heating system or household use, which can be rapidly and easily installed in any room, even if lacking an exhaust gas hood.
According to the present inventiorl, there is provided a gas-fired water-heating sy~tem for producing hot water, comprising (a) a gas-fired boiler including ~k ','~,', , ~.;~ I".
a tank for containing water and an exhaust duct for exhausting flue gas from the boiler; and (b) a toroidal-chamber regenerative compressor for drawing combustion air into the boiler and for expelling flue gas from the boiler via the exhaust duct.
The present invention also provides a gas-fired water-heating system for producing hot water, comprising (a) a gas fired boiler including a tank for containing water and an exhaust duct for exhausting flue gas from the boiler; and (b) a toroidal-chamber regenerative compressor for drawing combustion air into the boiler via a first pipe and for expelling flue gas from the boiler via the exhaust duct and via a second pipe, said second pipe being disposed within said first pipa.
A toroidal chamber regenerative compressor is a compressor in which the vanes, located around the periphery of an impeller, rotate within a toroidal chamber the cross-sectional area of which is greater than that of the vanes, so that the fluid drawn into the compressor, in addition to undergoing the rotational motion caused by the impeller, also undergoes a helical motion within ths toroidal chamber, so that the fluid flows several times between the vanes of the impeller during its path from the inlet to the outlet o~
the compressor. Each path between the vanes of the impeller can thus be regarded as a convent~onal compression stage, whereby one obtains more than one compression in which the fluid is accelerated. Accordingly, the term regenerative is applied to such compressors.
Thus, according to the present invention, the circulation of the inflow of the combu~tion air and of the outflow of the flue gas is a forced flow, produced by the toroidal-chamber regenerative compressor. This forced flow mak~s it possible to use small-diameter pipes for the ~ ., delivery of air and for the exhausting of the flua gas, with the consequent need for a hole of small diameter only through the wall. This c~nnot be accomplished by means of a normal fan, which has generally a small delivery head and a large flowrate, and hence characteristics diametrically opposite to the necessary ones.
In fact, in as much as a water-heating system .is generally fastened onto a wall ~ar away from the main wa~ o~
the bathroom, a rather long run exists for both the flue gas lo and the combustion air, and hence the need arises for a large delivery head, whilst the flowrate is generally small.
In the present invention, the forced flow is achieved by means of a toroidal-chamber regenerative compressor, which makes it possible to have a large delivery head with small flowrates, and the combustion air can be drawn from the outside through a pipe that can have a small diameter, inside which another small-diameter pipe is coaxially provided, through which the exhaust gas is expelled, which thus pre-heats the combustion air, with a consequent increass in system efficiency.
According to a variant of the invention, the combustion air may be drawn from the same room in which the system is installed, rather than from the outside, and consequently only one small-diameter pipe is needed, for conveying the flue gases to the outside.
The invention will now be descri~ed, by way of example, with reference to the drawing and schematic perspective view, a gas-fired water-heating system according to the invention, installed inside a xoom lacking an exhaust gas hood.
Referring to the Figure, there is shown two of the walls 2 and 3, and a window 4, of a bathroom 1. To wall 2, there is fastened, by means of support brackets (not shown), .,. ~
a gas-fired water-heating boiler 5, for heating ths water contained inside a storage tank 6 of the boiler 5.
Combustion air is supplied to a burner 7 of the boiler 5 by a toroidal-chamber regenerative compressor 8, which draws air from the outside through pipes 9 and 10. Coaxially with the pipe 9, there is another pipe 11 which also leads to the outside of the room 1, and is tightly connected to a flue gas exhaust duct 12 of the boiler 5. Thus, the flue gas is exhausted to the outside according to the direction of arrow 13, i.e. countercurrently to the flow direction 14 of the combustion air, which is thereby pre-heated. The duct 12 extends axially through the storage tank 6, so that the hot flue gas heats the water contained inside the tank 6.
