Abstract

The two pipes for circulating the water are connected to each other via a thermal compensator which is thermally disconnected from the central body of the boiler. The compensator comprises a heat conducting body which is cooled by the pipe in operation, causing it to cool the pipe which is not in operation. The pipes extend in a spiral direction around the central body. Combustion gases flow in a vertical direction through the central body.

Description

Gas /water warmtewisselaar, met gebruik thermische compensatorGas / water heat exchanger, with use of thermal compensator

De uitvinding heeft betrekking op een gas-water warmtewisselaar, te gebruiken in ketels voor centrale verwarming en tapwatervoorziening. De uitvinding omvat een centraal lichaam 5 (ketellichaam), waardoor de verbrandingsgassen in hoofdzaak vertikaal stromen, en twee waterleidingen die in hoofdzaak spiraalsgewijs rond dit centrale lichaam verlopen. Een van de waterleidingen dient voor de verwarming van water voor de centrale verwarming, door de ander wordt te verwannen drinkwater geleid.The invention relates to a gas-water heat exchanger, to be used in boilers for central heating and tap water supply. The invention comprises a central body 5 (boiler body), through which the combustion gases flow substantially vertically, and two water pipes which extend substantially spirally around this central body. One of the water pipes serves to heat water for central heating, while drinking water to be heated is led through the other.

Door toepassing van deze constructie wordt, met name bij de tapwaterbereiding, een hoog 10 rendement gehaald doordat de verbrandingsgassen efficiënt gecondenseerd kunnen worden. Dergelijke constructies zijn bekend onder andere uit patent NL9401061.By applying this construction, a high efficiency is achieved, in particular in tap water preparation, because the combustion gases can be efficiently condensed. Such constructions are known from, among others, patent NL9401061.

Genoemde watercircuits moeten apart van elkaar in bedrijf kunnen zijn. Een van de problemen die zich voordoen is dat het stilstaande water in circuit 1, wanneer alleen circuit 2 15 in bedrijf is, te heet wordt (en andersom). Dit bezwaar wordt in deze uitvinding opgevangen door de CV en de tapwaterleiding spiraalsgewijs om en om te leggen. Op deze wijze wordt een voldoende koeling bereikt, ook van het circuit dat niet in bedrijf is. De twee watercircuits zijn in principe gelijkwaardig, zij het dat het CV circuit over het algemeen een grotere hydraulische capaciteit en diameter zal hebben.The aforementioned water circuits must be able to operate separately from each other. One of the problems that occurs is that the stagnant water in circuit 1, when only circuit 2 is in operation, becomes too hot (and vice versa). This drawback is obviated in the present invention by alternating the central heating and the tap water pipe. Sufficient cooling is achieved in this way, also for the circuit that is not in operation. The two water circuits are in principle equivalent, although the heating circuit will generally have a larger hydraulic capacity and diameter.

In een gunstige uitvoeringsvorm worden de waterleidingen met een klikconstructie aan het ketellichaam verbonden. Het ketellichaam heeft, in de lengterichting nokken, die van uitsparingen worden voorzien. Deze uitsparingen lopen naar binnen toe iets uit, zodanig dat de leidingen hierin vastgeklikt kunnen worden.In a favorable embodiment, the water pipes are connected to the boiler body with a click construction. The boiler body has cams in the longitudinal direction which are provided with recesses. These recesses extend slightly inwards, such that the pipes can be snapped into them.

25 In deze gunstige uitvoeringsvorm is het ketellichaam van sleuven voorzien met een zodanige vorm dat de leidingen in deze sleuven vallen, zodanig dat een optimaal contact tussen het ketellichaam en de leidingen is gewaarborgd.In this favorable embodiment the boiler body is provided with slots of such a shape that the pipes fall into these slots, such that an optimum contact between the boiler body and the pipes is guaranteed.

Deze uitvinding maakt gebruik van een thermische compensator. Dit is een 30 (warmtegeleidend) lichaam dat de twee genoemde leidingen met elkaar verbindt, maar niet (of zeer weinig) in contact staat met het centrale ketellichaam. Deze compensator wordt gekoeld door de leiding die op dat moment in bedrijf is, en koelt daardoor ook de leiding die niet in bedrijf is. Er vindt geen (of zeer weinig) afvloeiing van warmte van het ketel-lichaam via de compensator plaats.This invention uses a thermal compensator. This is a (heat-conducting) body that connects the two said lines together, but is not (or very little) in contact with the central boiler body. This compensator is cooled by the pipe that is currently in operation, and therefore also cools the pipe that is not in operation. There is no (or very little) outflow of heat from the boiler body via the compensator.

De compensator kan technisch op verschillende manieren worden uitgevoerd. Een gunstige uitvoeringsvorm is een klemband die rondom het ketellichaam en de daarom bevestigde leidingen wordt aangebracht. Een ander uitvoeringsvorm bevat strips, die in de lengterichting over de leidingen liggen. Bij alle uitvoeringsvormen worden een goed contact tussen de 5 leidingen en de compensator gegarandeerd, bijvoorbeeld door halfronde sparingen in de compensator aan te brengen.The compensator can be technically implemented in various ways. A favorable embodiment is a clamping band which is arranged around the boiler body and the pipes attached therefor. Another embodiment comprises strips which lie over the pipes in the longitudinal direction. In all embodiments, good contact between the lines and the compensator is guaranteed, for example by providing semicircular recesses in the compensator.
