Abstract

The water in a circulating water domestic central heating system is heated using microwaves to obtain higher energy conversion efficiencies. A microwave generator heats water in a heating chamber. A mode stirrer rotates inside the heating chamber to improve the conversion efficiency. The installation offers low cost and good environmental compatability. There are no exhaust gases and a large proportion of the energy delivered is converted to heat inside the water volume. Additionally the microwave excites the hydrogen atoms in the water, inhibiting the formation of calciferous deposits in the heating systems. Regulation and safety devices are fitted to prevent overheating to cool the generator and to hold water in till it is sufficiently heated.

Description

DESCRiPTION b) La présente invention concerne le chauffage central d'une installation
domestique ou industrielle au moyen d'un générateur d'énergie dont le
fonctionnement est exclusivement électrique.DESCRIPTION b) The present invention relates to the central heating of an installation
domestic or industrial by means of an energy generator whose
operation is exclusively electric.

c) Les installations de chauffage central conventionnelles brûlent une quan
tité importante de combustible et comprennent un certain nombre d'élé
ments dont un dispositif d'évacuation des gaz contribuant à la pollution
de l'environnement. Ces installations sont d'autre part assez coûteuses
et leur amortissement est plus ou moins long. D'autre part un entretien
périodique est nécessaire qui comprend aussi le ramonage des cheminées,
lesquelles perdent une importante quantité de chaleur de par leur propre
conception.c) Conventional central heating systems burn a quan
significant amount of fuel and include a number of ele
elements including a gas evacuation device contributing to pollution
of the environment. These installations are also quite expensive.
and their amortization is more or less long. On the other hand an interview
periodic is necessary which also includes chimney sweeping,
which lose a significant amount of heat by their own
design.

d) Le dispositif selon l'invention a l'avantage d'éviter ces inconvénients
grâce à l'utilisation d'un générateur de micro-ondes permettant de réa
liser une économie substantielle lors de son installation ou adaptation
et en période d'utilisation. Ce dispositif, qui a recours à l'électrici-
té exclusivement, dispense donc l'utilisateur de s'approvisionner en
combustible traditionnel liquide ou gazeux et permet, en n'étant tribu
taire que de l'électricité alimentant le générateur de micro-ondes,lui
même faible consommateur d'énergie, de réduire très sensiblement les
frais de chauffage. De plus, l'émission de micro-ondes a pour caracté
ristique principale le chauffage direct des atomes d'hydrogène qui a
pour conséquence l'annulation du dépôt de calcaire dans le système.d) The device according to the invention has the advantage of avoiding these drawbacks
thanks to the use of a microwave generator allowing
read a substantial saving during its installation or adaptation
and during periods of use. This device, which uses electric-
exclusively, therefore exempts the user from obtaining
traditional liquid or gaseous fuel and allows, by not being a tribe
shut up that electricity powering the microwave generator,
even a low energy consumer, to significantly reduce
heating costs. In addition, the microwave emission has the character
main ristic the direct heating of hydrogen atoms which has
as a consequence the cancellation of the lime deposit in the system.

D'autre part, ce type de chauffage instantané, en excluant toute perte
directe ou indirecte de chaleur, permet de réaliser par son principe de
fonctionnement une économie d'énergie très importante par rapport aux
autres installations. L'utilisation exclusive et modérée de l'électricité,
le faible coût de l'installation, le coût relativement faible de l'appa
reil, la simplicité de son fonctionnement et les frais d'entretien ré
duits au minimum font de ce dispositif un économiseur d'énergie remar
quable.On the other hand, this type of instant heating, excluding any loss
direct or indirect heat, allows to realize by its principle of
very significant energy savings compared to
other facilities. The exclusive and moderate use of electricity,
the low cost of installation, the relatively low cost of the device
reil, the simplicity of its operation and the maintenance costs re
at least make this device an energy saver remar
fair.

f) Tel qu'il est représenté, le dispositif est composé d'un réservoir en
acier, inoxydable de préférence, isolé extérieurement par le matériau
isothermique 14 et comprenant essentiellement un générateur de micro
ondes 1 (type Magnetron) et une turbine de renvoi d'ondes 2 actionnée.f) As shown, the device consists of a tank in

par un diffuseur d'eau 8. L'eau circule en circuit fermé grâce à l'acce-
lérateur 5 qui se met en route automatiquement dès que le générateur
fonctionne. Le circuit est fermé jusqu'à la température maximale de 90"-
afin que l'eau du système ne soit pas portée à ébullition - et pour ce
faire le dispositif thermostatique de sécurité 11 agit directement sur le
générateur. Le calorstat 12, monté sur le tuyau de sortie 4,a pour
fonction de laisser écouler l'eau chauffée à 90" dans le circuit de chauf
fage. Le clapet à pression constante 6 permet d'obtenir un circuit fermé
nécessaire à la bonne marche du dispositif. La vanne anti-retour 7, montée
sur le tuyau-d'arrivée d'eau 3, retient l'eau contenue dans l'appareil.by a water diffuser 8. The water circulates in a closed circuit thanks to the access-
lerator 5 which starts automatically when the generator
works. The circuit is closed up to the maximum temperature of 90 "-
so that the system water is not brought to a boil - and for this
make the thermostatic safety device 11 acts directly on the
generator. The calorstat 12, mounted on the outlet pipe 4, has for
function to let the water heated to 90 "flow into the heating circuit
fage. The constant pressure valve 6 provides a closed circuit
necessary for the proper functioning of the device. The non-return valve 7, mounted
on the water inlet pipe 3, retains the water contained in the appliance.

La bride d'étanchéité 10 permet la fixation de l'écran de verre 9 sur la
paroi de la chambre à eau du dispositif et le générateur 1 est refroidi
par le dispositif de refroidissement extérieur 13.The sealing flange 10 allows the fixing of the glass screen 9 on the
wall of the device's water chamber and the generator 1 is cooled
by the external cooling device 13.

Le générateur de micro-ondes 1, actionné par le thermostat 11 lui-même
programmé à la température d'eau voulue, émet ses ondes au travers de
l'écran de verre 9 dans la chambre de chauffe 15 où se trouve la turbine
de renvoi d'ondes 2, elle-même actionnée par le diffuseur d'eau 8. La
turbine renvoie donc les micro-ondes dans tous les sens et permet ainsi
une utilisation maximale de l'effet produit par ces ondes sur les atomes d ' hydrogène. The microwave generator 1, actuated by the thermostat 11 itself
programmed at the desired water temperature, emits its waves through
the glass screen 9 in the heating chamber 15 where the turbine is located
wave referral 2, itself actuated by the water diffuser 8. The
turbine therefore returns microwaves in all directions and thus allows
maximum use of the effect produced by these waves on hydrogen atoms.

g) Ce dispositif de chauffage est destiné principalement aux habitations
privées mais peut être utilise industriellement au moyen d'appareils
identiques de plus grande capacité. g) This heating device is mainly intended for homes
private but can be used industrially using devices
identical with higher capacity.
