FR2580383A1 - Hot-air generator with production of hot condensation water - Google Patents

Abstract

Heating device making it possible on the one hand to distribute hot sanitary water at a constant temperature and on the other hand to distribute heating by a constant air flow at a variable output temperature (between 22 DEG and 48 DEG C), with optimum efficiency. This device functions with high efficiency by virtue of the fact that the ends of the fire tubes leaving the tank are at a condensation temperature, and by virtue of the design of the internal connection of the fins 4 and of the tank 1, and, lastly, by virtue of the insulation process in non-heating periods which makes it possible to keep the tank 1 in a closed enclosure.

Description

 The present invention relates to the heating of dwellings and the production of domestic hot water for these said dwellings. provided that they are insulated to H 2 E 85 standards.

 The present invention is a hot air generator with optimum efficiency, thanks to the condensation phase which is used for heat recovery.

And a reserve of hot water maintained at a minimum temperature of 50 "and maximum of 70" C. The latter is the overall caloric tank and is either in the heat loss phase from the outside thanks to the fins (4), or in the stagnation phase, i.e. the air intake around the balloon (1) being immobile and stagnant, plays the role of insulator and thus makes it possible to conserve domestic water at a suitable temperature for comfort. The small losses that may still remain are compensated for by starting the burner (2) from time to time.

 The temperature-delta room thermostat control system allows more or less air to pass from the fan (3) into contact with the fins (4) thanks to a stepping motor (14) which regulates the orifices ( 12) and (13) simultaneously.

The orifice (12) closes when the orifice (13) opens and vice versa, this to admit.

be at the fan (3) a constantly identical amount of air.

 The need for this constant volume of air is necessary for regular distribution in each room of the apartment to be heated.

 In systems of the same kind currently on the market, air heating is obtained either by an independent circuit (sometimes two blades of water), or by direct heating of the burner. In these two cases, the average drawback is either the setting in motion of the sanitary water creating a more significant loss in the non-heating phase, or in the second case, an excessive overheating of the air and therefore loss of calories from the fumes beyond what is necessary.

 The present device aims to obtain a heating of the premises and maintaining the sanitary water at temperature by using almost all of the calories emitted by the heat source which is in the present case a gas burner but which could be any other means. emission of calories (resistance or fuel ...).

 The device object of the invention, is composed of a water tank (1) in which is embedded a burner and its smoke evacuation pipe (5) performing a mouth whose outlet (8) allows the evacuation condensations (10) and the outlet of the burnt gases (9). Around the balloon (I) are added fins (4) by half-rockets.

The latter are pressed onto the balloon (I) by a putty with a high powder metal content so that contact is made as intimately as possible, or are welded.

 A jacket (they) in galvanized sheet surrounds the fins (4) so as to allow the passage of the air flow to be heated and thus to ensure a distribution and an honor.

 generosity of the flow on the fins.

 Around this shirt (18) is wound an insulation (11) in glass wool and the whole is covered with a painted external envelope (15) of parallelepiped shape giving the external appearance of the device.

 In the lower part, a removable filter is slid horizontally to create a dust barrier.

The upper part of this device on the board (1) consists of a box
supporting a fan (3) creating a depression and which has the possibility of operating a suction, either by the grid (12) or by ltorifi (e (13).

 The gate opening mechanism and the orifice shutter (13) are mechanically linked. The grid (12) has an opening with lamellae bones <: illantes.

 The shutter of the orifice (13) is a pivoting plate relative to the motor (14) and coming by rotation to obstruct the orifice (I 3).

 The same process is established on the plan (-he (2) (variant). The flaps (12) and (13) are mechanically connected by linkage so that (12) is on the horizontal horizon when (13) is also horizontally and vice versa that (12) is vertically when (13) is also.

 The description of the invention can be used in all cases of a house or a room provided that it is isolated to H 2 E 85 standards and in particular to all rooms which need heating and distribution of domestic hot water.

Claims (5)

 1s EVENDlCATlONS Heating driven by a fan (3) recovers calories when passing over aluminum fins (4) intimately linked to the domestic hot water tank (A), and domestic hot water is given by the fact that pumping is done in a storage tank (1) and maintained at constant temperature by a submerged gas burner compensating for the loss of calories.  1) Device giving domestic hot water and modulated heating, by the same heat source: heating given by the fact that the air flow of  2) Device according to claim I characterized by the fact that the end of the smoke evacuations (8) comes out at the bottom and allows to reach the condensation joint and thus bring an increase in calories.  3) Device according to claim 1 characterized in that the transmission ae heat from the balloon I to the air stream is obtained by intimate contact of the fins to the balloon made by a paste with a high content of powdered metal thus allowing maximum transmission .  4) Device according to claim i characterized in that the modulation of the heating is obtained by the more or less large opening of the closing valves (13) having in their closed position the possibility of maintaining the balloon in an isolated cocoon and causing at the same time the fresh air through the grid (12) and having in their closed position the maximum of calories distributed by the fan.  5) Device according to claim 4, characterized in that the movement of the gate closing valves (12) and valve (13) can be stopped in their course at a precise moment of equilibrium thanks to a geared motor (14) distributing the right amount of calories needed to meet the demand triggered by a room thermostat.
