Description

TESTO DELLA DESCRIZIONE TEXT OF THE DESCRIPTION

L?invenzione concerne un dispositivo di accumulo e distribuzione del calore per impianti di riscaldamento ad acqua, in particolare derivato da una o pi? caldaie a combustibili solidi, per l'alimentazione del radiatori e contemporaneamente per la produzione di acqua calda sanitaria. The invention relates to a heat storage and distribution device for water heating systems, in particular derived from one or more? solid fuel boilers, for powering the radiators and at the same time for the production of domestic hot water.

E' noto che attualmente l'acqua calda per il ri scaldamento degli ambienti e quella per usi sanitari vengono prodotte con dispositivi separati, cio? caldaie e scaldabagni o boiler, e utilizzando petrolio, energia elettrica edaltre fonti energetiche costose, evengono quindi distribuite mediante sistemi ed automatismi complessi e sofisticati. It is known that currently hot water for space heating and sanitary water are produced with separate devices, that is to say? boilers and water heaters or boilers, and using oil, electricity and other expensive energy sources, they are then distributed through complex and sophisticated systems and automatisms.

In detti impianti, inoltre, si verifica spesso la formazione di bolle di vapore nelle tubazioni, con conseguenti difetti di funzionamento e pericoli di deflagrazioni ai quali si ovvia disponendo le necessarte cassette di espansione nelle soffitte o, in generale, in ambienti posti in alto? Furthermore, in said systems, the formation of steam bubbles often occurs in the pipes, with consequent operating defects and danger of deflagrations which can be avoided by arranging the necessary expansion boxes in the attics or, in general, in high-rise rooms.

Scopo dell'invenzione ? quello di evitare la formazione di eccessiva condensazione dovuta al gra diente termico tra il focolare della caldaia e l?impianto di distribuzione, sempre verificato quando la caldaia ? inserita direttamente nel circuito dei raalatori? Purpose of the invention? to avoid the formation of excessive condensation due to the thermal gradient between the boiler hearth and the distribution system, always checked when the boiler? inserted directly into the radiator circuit?

Secondo scopo ? quello di smaltire il calore, in caso di black-out o in altra occasione nella qua le lo smaltimento del calore non possa avvenire re golarmente per mezzo delle pompe attualmente usate, per esemplo quando si verifica qualche avaria funzionale Second purpose? to dispose of the heat, in the event of a black-out or on any other occasion in which the dissipation of heat cannot take place regularly by means of the pumps currently used, for example when some functional failure occurs

Ulteriore scopo ? quello di consentire l'espan slone delle bolle di vapore, eventualmente formate, direttamente nell?atmosfera, consentendo alla pompa di circolazione di tipo noto di far circolare la sola acqua a temperatura inferiore a quella di ebollizione. Further purpose? that of allowing the expansion of the steam bubbles, possibly formed, directly in the atmosphere, allowing the circulation pump of the known type to circulate only the water at a temperature lower than the boiling point.

Inoltre il dispositivo inventato, opportunamen te coibentato e rivestito, pub essere installato irettamente nell ?appartamento o nelle strutture condominisi prive di soffitte o simili, con la so la condizione di essere posto pi? in alto del corpi scaldati e della caldaia, , In addition, the invented device, suitably insulated and coated, can be installed directly in the apartment or in condominium structures without attics or the like, with the only condition of being placed more in the apartment. at the top of the heated bodies and the boiler,

Tutti i suindicati scopi si raggiungono con una cassetta di espansione, coibentata a aperta su perlorsente , posta in posizione devata rispetto alla caldaia alla quale ? collegata, e contenente nel suo interno un boiler, per la produzione di acqua calda, atta ad essere distribuita agli impianti sa nitari, mentre detta cassetta ? collegata all?impianto dei radiatori in tendo tale che l?acqua del detto boiler viene riscaldata per contatto con quella della cassetta proveniente dalla caldaia, a seguito del la circolazione naturale e la produzione di acqua calda sanitari risulta quindi prioritaria rispetto a quella di distribuzione ai radiatori. All the aforementioned purposes are achieved with an expansion box, insulated open on perlorsente, placed in a deviated position with respect to the boiler to which? connected, and containing inside a boiler, for the production of hot water, suitable for distribution to sanitary systems, while said box? connected to the radiator system in such a way that the water of the said boiler is heated by contact with that of the box coming from the boiler, as a result of the natural circulation and the production of sanitary hot water is therefore a priority over that of distribution to the radiators.

Detto boiler inoltre, ? previsto dotato di una resistenza elettrica incorporata applicata senza alcun contatto con l' ambiente liquido mediante un attac co, a tenuta d?acqua realizzato sulla parete della cassetta, in modo da realizzare un funzionamento autonomo e sicuro ed una rilevante rapidit? di riscal -damento. Un rubinetto a galleggiante consente l'in -grosso dell?acqua fredda, dell' impianto idraulico, dentro la cassetta di espansione , che ? collegata a la caldaia da tubazioni di ingresso dell'acqua calda e uscita di quella pi? fredda e da analoghe tuba zioni dirette all'impianto dei radiatori, con l'in terposizione di una pompa elettrica di tipo noto. Said boiler also,? provided with a built-in electric resistance applied without any contact with the liquid environment by means of a watertight connection made on the wall of the box, in order to achieve an autonomous and safe operation and a remarkable rapidity. of heating. A float tap allows the wholesale of cold water, of the plumbing system, inside the expansion box, which? connected to the boiler by the inlet pipes of the hot water and the outlet of the pi? cold and similar pipes directed to the radiator system, with the interposition of an electric pump of a known type.

La schematizzazione di una variante preferita del dispositivo, esemplificativa e non limitativa, ? rppresentata nelle accluse tavole di disegni alle figg. 1-2-3? The schematic diagram of a preferred variant of the device, exemplary and not limiting,? represented in the accompanying tables of drawings in figs. 1-2-3?

Il termostato 14, collegato sul boiler 10, in prossimit? della tubazione 12 di ingresso dell'acqua fredda, viene tarato in modo tale da consentire la partenza della pompa di cir-colazione dell?impianto del radiatori, quando l?acqua avr? raggiunto una temparatura di soglia, che pu? essere 45?-50?C, ma per la presenza del piccolo foro 15 sulla tubazione 12 in occasione del prelevamento dell?acqua calda sani taria, detto termostato viene raggiunto dall'acqua fredda in entrata nel boiler 10 e quindi determina l' arresto della pompa di circolazione, dell'impianto dei radiatori, riservando in tal modo, e privile giando, l'assorbimento del calore prodotto dalla cal daia al solo impianto sanitario. The thermostat 14, connected on the boiler 10, in the vicinity? of the cold water inlet pipe 12, is calibrated in such a way as to allow the circulation pump of the radiator system to start, when the water will have? reached a threshold temperature, which can? be 45? -50? C, but due to the presence of the small hole 15 on the pipe 12 on the occasion of the withdrawal of the hot sanitary water, said thermostat is reached by the cold water entering the boiler 10 and therefore determines the stop of the circulation pump, of the radiator system, thus reserving, and giving priority, the absorption of the heat produced by the boiler to the sanitary system only.

E' evidente che in tal modo si ottiene una prio rit? dell'acqua calda dei servizi sanitari rispetto a quella del riscaldamento e si realizza un immediato beneficio nelle utilizzazione delle caldaie a com bustibili solidi di qualsiasi potenzialit? Is it evident that in this way a priority is obtained? of the hot water of the sanitary services compared to that of the heating and an immediate benefit is realized in the use of solid fuel boilers of any potential?

Per quanto concerne la resistenza incorporata 16. questa ? solidale all'attacco dotato di manicotto con riduzione filettata 17 che, avvitandosi nella sede 18, sporgente dal boiler 10, realizza la strizio ne delle guarnizioni 19 e 20 impedendo qualsiasi con tatto con l'acqua, a fin? di sicurezza. As for the built-in resistance 16. this? integral with the attachment equipped with a sleeve with threaded reduction 17 which, by screwing into the seat 18, protruding from the boiler 10, tightens the seals 19 and 20, preventing any contact with water, until? safety.

Un secondo termostato provvede all'azionamento della pompa, a volont?, anche quando l'acqua ? calda, mentre un ulteriore termostato sar? disposto a rego lare il funzionamento della resistenza 16. A second thermostat activates the pump, at will, even when the water? hot, while an additional thermostat will be? willing to regulate the operation of the resistor 16.
