Description

radiator

The present invention relates to a radiator, comprising a at least on one outside with ceramic, marble, stone or glass-covered container, wherein at least one wall of the container as a to a circuit of a

Heat transfer material connectable heat exchanger is formed. Furthermore, a method for producing a radiator according to the invention is given.

Various designs of radiators are known from the prior art, which usually serve shapely and compact radiator for individual rooms of a building. Such radiators are usually connected to a circuit of

Closed heat transfer material. The heat transfer material, usually hot water is used, enters the designated as flow supply line in the radiator and leaves it after heat loss in the designated as return drain line. In most cases, several radiators are connected in series to a circulating line filled with circulating heat transfer medium. The circulation line is fed by a common, central hot water heater and thus ensures a constant high flow temperature of the heat transfer material.

The disadvantage of such radiators, which are made for example of a metal casting material or a cold rolled steel sheet, only a very small

To cite heat storage effect. Once the supply of hot

Heat medium is interrupted, the radiator cools very quickly, which is perceived as unpleasant. A current supply of the radiator with hot water, however, is disadvantageously reflected in high operating or heating costs.

To increase the storage effect of a radiator, for example

Storage tiles are heat-conductively attached to one side of the radiator. However, in this embodiment, the period until the radiator after interrupting the

Supply of heat transfer material is cooled, only slightly extended.

The present invention therefore has as its object to avoid the disadvantages known from the prior art for a radiator and to provide a radiator that offers a much higher heat storage capacity in comparable with a radiator, compact dimensions. This object is achieved in a radiator according to the preamble of claim 1 with the features of the characterizing part of claim 1. The subclaims relate to particularly advantageous embodiments of the invention.

It is advantageous in a radiator according to the invention, comprising a at least on one outer side with ceramic, marble, stone or glass occupied container, wherein at least one wall of the container is designed as a connectable to a circuit of a heat transfer material heat exchanger, defined by the container an interior, the is filled with a phase change material, wherein the heat exchanger protrudes into the phase change material or passes through it.

By located in the interior phase change material is the

Heat storage capacity of a radiator according to the invention in comparison to

conventional radiators with an inwardly open air space significantly improved, without exceeding the compact dimensions of radiators. In addition, a particularly energy-saving space heating is possible with a radiator according to the invention. Furthermore, in a radiator according to the invention by the heating of the ceramic outer skin a forced heat radiation in the form of particularly comfortable infrared heat is achieved.

Thus, the advantages of conventional radiators, which can be provided due to their compact dimensions in each living space and flexible exchange, as well as the benefits of a tiled stove, which is usually a particularly high

Has heat storage capacity and emits a high proportion of radiant heat, combined in a radiator according to the invention.

As a heat exchanger, which thus forms at least one wall of the container, for example, a known from the prior art radiator can be used.

Particularly useful in a radiator according to the invention, at least two opposite walls of the container designed as a heat exchanger.

Likewise, it is possible within the scope of the invention that even more walls, that is more than two walls, of the container are designed as heat exchangers. It is advantageous in a radiator according to the invention, the container at its unoccupied, so not occupied with ceramic, marble, stone or glass, outer sides at least partially provided with insulation.

Due to the insulation, which is advantageously arranged on the uncovered outer sides of the container, the heat radiation from the occupied outer sides is significantly improved and prevents the most unwanted heat radiation from the uncovered outer sides. The proportion of radiated as infrared radiation from the occupied outer sides heat is advantageously increased by the insulation and the long-lasting

Heat storage effect of the radiator according to the invention thereby further extended. Unwanted heat losses, which occur for example in an uninsulated container which is attached to a building wall, by heat radiation to the wall, are reliably prevented due to the isolated outer sides of the radiator.

In the context of the invention, it is for example also possible to incorporate the container of a radiator according to the invention in a recess of a wall or a wall niches that for a viewer only the decorative, occupied with ceramic, marble, stone or glass, front of the radiator is visible. In these installation positions insulation of the blank outer sides of the container is particularly useful.

It is advantageous in a radiator according to the invention, the at least one as

Heat exchanger formed wall provided with a heat transfer material inlet port and a heat transfer material drain port.

In one embodiment of the invention is in a radiator of the heat transfer material inlet port or the heat transfer material discharge port with a

Heat transfer fluid flow controller provided.

Within the scope of the invention, control systems known from the field of radiator technology can be used for flow control, for example.

Particularly advantageous is a radiator according to the invention with at least one

Temperature sensor provided, which is preferably coupled to a temperature control device and projects into the filled with phase change material interior space or disposed on the occupied outside of the container. The temperature measurement of the temperature sensor is thus either directly in the interior filled with phase change material interior, or it is the surface temperature measured at the occupied with ceramic, marble, stone or glass outside of the container. It is also conceivable within the scope of the invention that a plurality of temperature sensors are provided which, for example, both the temperature of the phase change material in the interior of the container, and the surface temperature of the occupied outside of

Capture container.

The temperature detected by means of temperature sensors at the respective measuring point in the interior or on the occupied outside of the container is compared by a temperature control device with the room temperature of the surrounding living space. Once the desired set room temperature has been reached, the flow of the heat transfer medium is throttled or interrupted by the heat transfer material flow controller, and the flow is only reopened when the room temperature has risen by a certain amount

Temperature difference to the desired target room temperature, for example, by a temperature difference of 3 to 4 ° C, has dropped. The radiator according to the invention radiates primarily infrared heat. The surface temperature of the occupied for example with ceramic outer sides of the container are thus usually warmer in operation than the room temperature of the ambient air.

The occupied outer sides advantageously retain the same surface temperature for a particularly long time due to the high heat storage capacity of the radiator according to the invention.

Rapid temperature changes of the surfaces, as they are due to the low

Heat storage capacity when switching on and off of conventional radiators occur and are perceived as unpleasant, advantageously do not occur in a radiator according to the invention.

When using a radiator according to the invention, the room temperature of the ambient air differs only very slightly during a longer time interval, for example during 24 hours. The uniform delivery of radiant heat at about the same temperature level is perceived as particularly pleasant and comfortable.

In particular, when a heat storage or buffer is provided in the circulation of the heat transfer material, the time intervals in which the flow of the heat transfer material is throttled or interrupted by the heat transfer material flow controller, can be advantageously extended. Thus, a particularly efficient, energy-saving operation of a radiator according to the invention is possible. Depending on the requirement, it can For example, be sufficient to supply hot heat transfer material only two or three times a day during shorter heating intervals the radiator of the invention. During the longer time intervals in which the flow of the heat transfer material is interrupted and the radiator is not heated with hot heat transfer material, the high heat storage effect of the latent heat storage is particularly advantageous effect.

For heating the heat transfer material, such as water, in principle, any variant of a building heating is conceivable. Among other things, fuels such as fuel oil, vegetable oils or biodiesel can be used as liquid fuels, solid fuels such as coal, wood or other biogenic solid fuels, such as straw or biomass, as well as natural gas, liquid gas or biomethane as gaseous fuels. Furthermore, it is conceivable to accomplish the heating of the heat transfer material with a thermal solar system either alone or in combination with a fuel firing.

As a phase change material, a paraffin-containing medium is provided in a radiator according to the invention.

In the context of the invention it is further possible, depending on the application, other

Phase change materials such as salts (e.g., Glauber's salt, sodium acetate), salt hydrates, or organic compounds (e.g., fatty acids) as latent heat storage. It is essential that the latent heat of fusion, solution heat or heat of absorption of the phase change materials used are each substantially larger than the heat they can store due to their normal specific heat capacity without the phase transformation effect.

Depending on the melting temperature or solidification temperature of the phase change material used in each case of the temperature control device

Flow temperature of the heat transfer material controlled. The flow temperature is regulated so that it is above the melting temperature of the corresponding phase change material. By replacing the phase change material by a corresponding

Phase change material with a lower melting temperature, it is possible to lower the required flow temperature of the heat carrier.

Appropriately, in a radiator according to the invention, the walls of the container made of a metallic material. In a further development of the invention, a method for producing a radiator is indicated as a sequence of the following manufacturing steps:

Providing a radiator, comprising a heat carrier material inlet connection and a heat carrier material outlet connection, as a heat exchanger;

Closing the open side surfaces of the radiator by tight fastening, in particular by welding, side surface plates;

Arranging a closable phase change material filling opening and a closable phase change material discharge opening on the side surface plates; Covering, in particular gluing at least one outer surface of the radiator with ceramic, marble, stone or glass;

Preferably, attaching insulation to at least a portion of the blank outer surfaces of the radiator;

Filling the interior formed by the radiator and the side surface plates sealed thereto with a phase change material;

The filling with phase change material takes place either already during the production of the radiator or during assembly or commissioning on site.

The radiator is thus prepared for connection to a heat transfer material circuit.

Optional insulation is preferably attached to at least a portion of the blank outer surfaces of the radiator. In particular, when the highest possible heat transfer is to be achieved with an increased convection share with a radiator according to the invention, the unoccupied outer surfaces of the radiator, for example its back, remain without insulation.

A radiator according to the invention can in principle be used in every building, for example in private homes, public buildings and also in communal residential buildings. In addition, different embodiments of the radiator according to the invention, for example, with different sizes, all covered by the invention.
