Thermo insulated heat storage

Field of application of the invention

The present invention relates to a thermally insulated heat storage for heating and / or service water systems.

Characteristic of the known technical solutions

It is known that great efforts have recently been made to obtain energy in the form of heat by means of solar collectors or heat pumps. Regardless, efforts are constantly being made to improve the efficiency of conventional coal, gas and oil heating systems. In the case of heat recovery by means of solar panels, it is disadvantageous that in our latitudes, the sunlight is quite irregular and relatively weak in winter, so that with solar panels just when much energy is needed, i. In winter, not much heat can be gained continuously, so it is more important, in sunlight,

especially in winter, to recover and store as much heat as possible, to get over longer periods when the sun is not shining. This usually fails because the storage capacities are too low, usually have the hot water boiler, which are heated by means of the circulating solar collector liquid, only a capacity of 300 to 500 1, ie, that you do not get far with this amount of hot water, especially not then if you want to use the stored heat not only for heating the service water, but in addition or only for heating purposes.

In the case of coal, gas and oil heating is particularly endeavors) by control techniques by means of outdoor thermostats, located on the radiators thermostatic valves, by time relay for boiler after-heater and the like to increase the efficiency. A disadvantage, however, in these heaters, and in particular in gas and oil heaters, still the fact that due to the relatively low capacity of the boiler, the burner in relatively short time intervals on and off, so that the burner only burns over short periods, causing a strong loss of energy.

There are also known electric storage heaters that take advantage of the cheap nighttime electricity and store the heat in relatively small volume units. These storage heats up to very high temperatures, which not only causes special heat insulation problems, but also problems in terms of a rational and healthy dissipation of stored heat.

Object of the invention

The object of the invention is the development of a heat accumulator with. large heat storage capacity.

Explanation of the essence of the invention

The invention has for its object to provide an environmentally friendly heat storage, which allows on the one hand, the heat gained from solar panels or heat pumps or the like, with only relatively small temperature increases in the heat storage can be achieved, and on the other hand, allows more effective To increase the efficiency of coal, gas and oil heating., And from other types of heating or make sense to allow.

The object of the invention is achieved by the use of a thermally insulated heat storage, which contains as heat-storing medium water and / or another environmentally friendly liquid or a slightly melting substance is dimensioned correspondingly large and inside all or part of a heat radiation reflective coating or reflective foil lining, preferably a lining of highly polished aluminum foil has.

The invention thus provides a heat-insulated heat storage for heating and / or service water systems, which is characterized in that

a) the heat-storing medium contained in it is water and / or another environmentally friendly liquid or a slightly melting substance,

b) the storage capacity is correspondingly large,

c) it is provided in whole or in part with a heat radiation reflecting coating or reflective foil lining, preferably a lining of highly polished aluminum foil, and '

d) it has facilities for heat supply and heat dissipation.

As the heat-storing medium, water is particularly preferred according to the invention because it is readily available and particularly environmentally friendly. Of course, it is also possible to use other liquids instead of water, e.g. Glycerol, optionally in admixture with water, or oils, e.g. Paraffin oil or silicone oil. On the other hand, it may also be advantageous to use as a heat-storing medium according to the invention, a substance which, although solid under normal conditions, but melts even at relatively low temperatures. Substances of this type include, for example, hard paraffins with melting points between 50 ° and 62 ° C, waxes, low molecular weight inert polymers and very low melting alloys such. Woods alloy (melting point: 60 to 70 ° C). In such low-melting substances, the heat storage effect is increased by the fact that additional energy is needed for melting. If, for example, heat is added to a hard paraffin, its temperature rises steadily up to the melting point; then its temperature no longer increases for a long time, since all the heat energy supplied is used up for melting. Only when the whole

- * - 2Ί8051

Hard paraffin is melted, the hard paraffin heats up. This amount of heat necessary for melting is called heat of fusion. Upon cooling of the substance then this heat of fusion is released again in the form of heat of solidification in addition to the actual cooling.

The storage capacity of the heat accumulator depends on the one hand on the properties of the heat-storing medium used and on the other hand on its quantity. Preferably, the storage capacity should be so large that the stored heat without additional heating is sufficient to provide for a few days beyond a normal household with the usual amount of hot water.

Since water is particularly preferred according to the invention as a heat-storing medium, the heat storage preferably has a capacity of at least 1 500 l, more preferably one of about 5,000 to 15,000 l, and preferably a columnar, in particular cylindrical, vertically arranged shape. The inner diameter of such a hollow cylinder is for example about 0.8 m to 2.0 m at a height of about J> to 5 m. The cylinder jacket as well as the bottom and the cover may be made of any suitable material, that - if it does not already have enough thermally insulating acts additionally a thermally insulating layer, wherein the thickness of the insulating layer is based on the λ value (thermal conductivity) and so Thick is that practically no heat losses occur through the container shell, the bottom and the lid. The thermally insulating layer is preferably made of a rigid polyurethane foam and has a thickness of about 15 cm. The thermo-insulating layer can either directly form the heat storage as a self-supporting element or the insulation layer is applied to the container wall including the floor and ceiling outside or inside

218051

or introduced between corresponding cladding. The walls of the heat accumulator can consist of metal, plastic or concrete rings. The same applies to the cladding. For example, superposed concrete rings are advantageously used according to the invention, which are centrally surrounded by concrete rings, the diameter of which is preferably 30 cm larger than the diameter of the inner concrete rings. The intermediate space between the concrete rings is then foamed in place with rigid polyurethane foam, whereby the foaming is advantageously carried out stepwise, i. Depending on the height of the concrete rings, one or two inner concrete rings and a corresponding number of outer concrete rings are laid and the intermediate space is filled with foam before the next concrete rings are stacked on top of each other. Of course, instead of the outer concrete rings corresponding rings made of metal or plastic can be used or the outer rings are made of concrete and the inner rings are made of metal or plastic. Of course, at the same time, the inner and outer rings made of metal or plastic. In addition, the foaming does not need to be done on the spot, but the heat storage k'onnen be delivered ready.

The cylinder jacket, the bottom and the cover of the heat accumulator · can also, as already mentioned, be designed as self-supporting elements, these elements being held together optionally by additional aids. For example, the cylinder shell can only be made of rigid polyurethane foam in the form of a pipe or it can consist of stacked pipe rings that correspond in construction to the concrete rings, or consist of two half-shells or several cylinder longitudinal segments. The half shells or the cylinder longitudinal segments either have a length,

218051

which corresponds to the desired height of the heat storage or they are dimensioned so that they give the desired height by additional superposition. In order to ensure a shift-safe superimposition, have both the tubes, the tube rings and the half-shells and the longitudinal segments at their foot and optionally head ends correspondingly shaped tongue-like projections or projections, as are common in the concrete rings.

Preferably, the cylinder longitudinal segments are further designed so that the inner and outer surfaces have the same radius of curvature. Due to the same radius of curvature, the cylinder longitudinal segments can be arranged in a space-saving and damage-safe manner during transport, without the corners being in any way endangered.

The half-shells preferably also have at their longitudinal edges tongue and groove or corresponding projections or depressions, while this is not necessary in the cylinder longitudinal segments, since they are formed at their longitudinal edges so that they come to rest on the principle of vault stones together. The position of the side surfaces of the longitudinal segments is designed so that the theoretical extension of the side surfaces passes through the cylinder longitudinal axis.

The half-shells or the cylinder longitudinal segments are held together preferably by steel bands, which are screwed together, for example at their ends, similar to hose clamps, or by stacked concrete rings.

The columnar, in particular cylindrical configuration in a vertical arrangement is therefore preferred because

is ensured by the fact that the hot water always collects in a relatively small space on the surface, from where it is either withdrawn or where the heat is discharged to one or more heat exchangers in which the service and / or heating water is heated.

Of course, the heat storage need not only have a columnar or cylindrical shape and be arranged vertically, but it may also be arranged horizontally or have the shape of a pyramid, a cone, a cuboid or a cube, but then a pyramidal or hemispherical or similarly designed attachment should be placed on the container, which ensures that the hot water can always accumulate in the thus limited, relatively small space.

The surfaces forming the inner surfaces of the heat accumulator are preferably coated with aluminum foil, in particular a highly polished aluminum foil. According to the invention, for example, the half-shells or the cylinder longitudinal segments can be continuously produced as sandwich elements, wherein the outer layers of aluminum foils and the core of rigid polyurethane foam. At this point, it is noted that for the feature that the heat storage inside a whole or part of a heat radiation reflective coating or reflective foil lining, preferably a lining of aluminum foil or the like, will claim not only in conjunction with the heat storage according to the invention protection, but also a separate protection for heat storage of another type, for example, for the smaller water heater with a capacity of 300 to 500 1.

In cases where the insulating housing of the heat

memory is not waterproof or susceptible to corrosion, in the heat storage at the upper end of the cylinder jacket a Fo.liensack attached, which is dimensioned so that it comes to rest on the ground and on the inner cylinder wall. If such a film bag is used, this film bag can also assume the function of the heat-reflecting lining, specifically if the film bag itself is coated or laminated with one of the heat-reflecting layer.

In view of the size of the inventively preferred large heat storage, v / these ground preferably, for example, in the case of one- and two-family houses, outside the house, preferably in the ground, set up. In many cases, it is possible with advantage to "convert" former sewer pits to the heat store according to the invention.

With regard to the various possible embodiments according to the invention, the features described in more detail below also apply.

Preferably, located above the heat-storing medium 6 is a gas cushion 7, which preferably consists of air or an inert gas, for example nitrogen. The gas cushion is usually hermetically sealed off from the outside atmosphere and dimensioned such that its volume is able to withstand normal conditions when heating the heat exchanger.

accumulating medium 6 accumulating pressure increase. On the other hand, it may also be advantageous if the gas cushion is not hermetically sealed off from the outside atmosphere, but is in communication with the outside atmosphere. In this way, a simple pressure equalization in the system can be achieved, provided that the connection with the outside atmosphere is designed so that greater evaporation losses are avoided. How the skilled person can create such a connection to the outside atmosphere is known to him. Of course, you can dispense with a special embodiment of the invention on the gas cushion completely, but then recommends to install elsewhere in a conventional heating pressure equalization vessel. Furthermore, it is possible that the heat-storing medium 6, e.g. the water preferably used, is under a pressure corresponding to the pressure prevailing in the water line pressure. On the other hand, it is of course also possible to connect the heat storage via a corresponding pressure reducing valve to the water line. This embodiment will be chosen especially if you want to consume the heated water in the heat storage directly as hot service water.

The means for supplying heat are preferably arranged slightly above the bottom of the heat accumulator, as a result of this, that the warm water accumulates in the upper part of the heat accumulator and always this. is heated at the bottom of the heat accumulator accumulating cold water. The device for supplying heat, for example, a heat exchanger, which is arranged at the bottom of the heat accumulator and which is fed by circulating water, which is heated, for example, in solar panels or in heat pumps. According to a particularly preferred embodiment of the invention, the water in the heat accumulator can be on the ground

- «2 18051

pumped out and passed directly through the solar panel or through the boiler of an oil, gas or coal burner and fed back to the heat storage at the top. Such an embodiment will be described in more detail below in connection with the use of a solar collector.

In many cases, however, it may also be more advantageous if the medium in the heat accumulator is heated by means of electrical energy, which in particular is inexpensive at night. For this purpose, then located at the bottom of the heat storage, an electrically heated heat source, for example, one Tnit is comparable to a large immersion heater.

Below the surface, preferably the means for heat dissipation, i. arranged corresponding heat exchanger through which the service and / or heating water is passed and heated therein. An expedient arrangement provides that two corresponding heat exchangers are arranged one above the other or side by side, whereby den.einen heat exchanger for the intended use of water and water. by the other the water intended for heating purposes is passed.

Just as the water serving as a heat-storing medium can be heated directly in solar collectors, the stored water can also be routed directly through the radiators of the heating system or through the underfloor heating. Exactly the same applies to the already mentioned case that you want to use the stored in the heat storage hot water as hot water directly.

A particularly interesting application of the heat accumulator according to the invention can be seen in a special combination with a solar collector, which receives a solar panel heater, which consists essentially of a solar collector, the heat storage according to the invention, the recirculation pipes, which allow the collector liquid through the solar collector and to circulate the heat storage in the circuit, and the actual radiator or service water system exists. This combination is characterized in that

(a) the thermally insulated heat accumulator 1 has a capacity of at least 1500 l and.in wholly or partly has a heat radiation reflecting Beschickung or reflective foil lining, preferably a lining of aluminum foil or the like,

(b) the collector liquid is not passed through the heat exchanger 1 located in the heat exchanger, but through the heat storage 1 itself and serving for heating the radiator water or · the hot water by a heat exchanger located in the heat exchanger 1, the capacity varies depending on the task, is directed

(c) there is a gas cushion 7 in the heat accumulator 1 above the collector liquid to be pumped around,

(D) the heat storage is designed so that the gas cushion 7 is located above the heat exchanger, which is arranged in the heat accumulator 1 so that it is located during operation of the solar collector slightly below the water surface 6,

(F) the solar collector is arranged so that during operation of the solar collector therein the collector liquid after switching off the circulation pump, which circulates the collector liquid, from the solar collector and the corresponding recirculation pipes through the inlet opening 8 and the suction 9 expire in the heat accumulator 1 can.

The Erfindungsv / esentliche is thus seen in the combination of the heat accumulator, the air cushion and idling of the solar collector at pump standstill, the emptying of the collector at pump standstill could only be achieved by working with the above-mentioned air cushion. This air cushion has to fulfill in this case thus two functions, once to allow the leakage of the collector in non-pumping operation and on the other hand to act as a pressure buffer, as not inconsiderable pressure differences during heating of the inner water of a temperature of about 20 to 25 C to 60 0 C. occur.

Preferably, the gas cushion 7 located in the heat accumulator 1 is connected via a pipeline to the highest lying channel in the solar collector via a valve located on the solar collector, which turns off when the circulating pump, i. the elimination of the internal pressure, opens and thus favors the leakage of the collector liquid from the solar collector.
