Abstract
Description
Le brevet principal concerne un chauffe eau fonctionaant par récupération de calories sur les installations frigorifiques, décrit dans le brevet d'invention dépose le 12.12.78 sous le numéro 78 34855. L'originali*é du procédé retenu est un système à double échangeur, solutionnant principalement le problème du dépat de tartre, il apporte aussi une solution au problème de la sécurité sur le plan de l'hygiène alimentaire. The main patent relates to a water heater operating by heat recovery on refrigeration installations, described in the invention patent filed on 12.12.78 under number 78 34855. The originality of the process used is a double exchanger system, mainly solving the problem of scale deposits, it also provides a solution to the problem of safety in terms of food hygiene.
L'addition à pour but de fournir un complément d'informations sur certains accessoires apportant des éléments complémentaires de sécurité et de développer de nouvelles possibilités d'utilisation de ce système de production d'eau chaude à d'autres applications. The purpose of the addition is to provide additional information on certain accessories providing additional safety elements and to develop new possibilities for using this hot water production system for other applications.
Dans-les chauffe eau traditionnels soient éléctriques soient à récupération de calories à simple échangeurs, la pression varie en fonÉtlondes températures intérieures de l'eau et il y a nécessité de prévoir une vanne dite de sécurité, pour évacuer le volume d'eau exédentaire. Dans les chauffe eau à double échangeur tel que nous les décrivont, il n'y a pas cet inconvénient et une simple soupape de sureté placée dans le haut du réservoir sera suffisante. In traditional water heaters are electric or heat recovery with simple exchangers, the pressure varies depending on the internal temperatures of the water and there is a need to provide a so-called safety valve to evacuate the volume of excess water. In double exchanger water heaters as we describe them, there is not this drawback and a simple safety valve placed at the top of the tank will be sufficient.
Par mesure d'hygiène il n'sst pas permis de chauffer de l'eau sanitaire directement drus un réservoir dans lequel circule un produit toxique. Les chauffe eau objet de ce brevet, par le système à double échangeur répond à ce règlement. La pression interne du réservoir est pratiquement nulle et en cas de rupture d'un des échangeurs, la pression monterait dans le réservoir et le manocontact prévu pour cet effet déclencherait l'alarme et stopperait le compresseur de l'installation frigorifique. For hygienic reasons, it is not allowed to heat domestic water directly from a tank in which a toxic product circulates. The water heaters object of this patent, by the double exchanger system meets this regulation. The internal pressure of the tank is practically zero and in the event of the rupture of one of the exchangers, the pressure would rise in the tank and the pressure switch provided for this purpose would trigger the alarm and stop the compressor of the refrigeration installation.
Ce système de production d'eau chaude est utilisable également en complément dans une installation de chauffage central à eau chaude. Devant l'intérêt de réserver les énergies stockables pour le chauffage d'hiver, il sera préférable d'utiliser ce dispositif de production d'eau chaude aux périodes favorables pour les producteurs d'énergie électrique. This hot water production system can also be used in addition to a hot water central heating installation. In the interest of reserving storable energies for winter heating, it will be preferable to use this hot water production device at favorable times for producers of electric energy.
Cette chaudière de préchauffage peut
avoir un ou plusieurs échangeurs primaires alimentés par
des sources différentes : solaires, pompes à chaleur ou
résistances électriques soient scule soient en addition
5soient en combinaison.This preheating boiler can
have one or more primary exchangers supplied by
different sources: solar, heat pumps or
electrical resistances either be added
5 are in combination.
Afin de pouvoir utiliser le disposi
tif présentement décrit comme condenseur unique dans un
système frigorifique à refroidissement à eau les échangeurs
présentent de nouvelles particularités . En un point inter10médiaire (10) de l'échangeur primaire une dérivation permet
d'évacuer l'eau vers l'extérieur. Une electro-vanne commandée
par un pressostat limiteur de pression permettra d'evacuer
l'eau de refroidissement comme sur un condenseur à eau tra
ditionnel. L'inertie créée par le système à double échangeur i5ne permettant pas un refroidissement suffisament rapide pour
abaisser la température du fluide réfrigérant, il est prévu
sur cette première partie de l'échangeur primaire que le re
froidissement se ferait dans un échangeur construit avec deux
tubes concentriques. Le fluide réfrigérant circulera au con- autre et l'eau de refroidissement a contre courant entre les
deux tubes. Une isolation du tube extérieur protège l'eau de
refroidissemnt contre le réchauffement par l'eau du ballon. In order to use the device
tif presently described as a single condenser in a
water-cooled refrigeration system exchangers
present new features. At an intermediate point (10) of the primary exchanger, a bypass allows
to evacuate the water to the outside. A controlled solenoid valve
by a pressure limiting pressure switch will allow to evacuate
cooling water as on a tra water condenser
additional. The inertia created by the i5 double exchanger system does not allow fast enough cooling to
lower the coolant temperature, it is expected
on this first part of the primary exchanger that the re
cooling would be done in an exchanger built with two
concentric tubes. The refrigerant will circulate in the other way and the cooling water will flow against the current
two tubes. Insulation of the outer tube protects the water from
cooling against heating by the water in the flask.
