Description

This invention relates to a heating device and more particularly to a radiator-type heating coil.

Various applications are known in the art for heating radiators, some of which are used for so-called "radiators". especially for heating wet rooms, washrooms, saunas and the like. The design of the radiators is carried out according to 10 standards in use in the industry.

In a sense, the industry also involves different types of heat exchangers. Thus, for example, a heat exchanger is known from British Patent Publication No. 2 013 313, in which heat is recovered from the intermediate space of two cell-type heating elements in the second cycle of water used as domestic hot water. On the other hand, a method for inhibiting the growth of legionella bacteria is also known from the English publication 2,237,863, which is also one of the purposes of the present invention. However, according to the publication, a different system is used, ie incoming cold water is first heated to a sufficiently high temperature to kill the bacteria and then cooled to suit the application.

The disadvantage of radiators in the domestic hot water cycle is that it has been discovered that * ·· «·:" * · the temperature of the water in the return cycle is too low. This is naturally due to the fact that the water is circulating cools through the radiator and increases cooling during the return • * 25 cycle, which means that especially Legionella, as mentioned above: **: as mentioned above, begins to proliferate in the network, causing obvious health problems. in addition to the disadvantages of the crop itself to the network.

It is an object of the present invention to provide a simple and inexpensive solution to the above problems. This is achieved by a heating radiator, the characteristic features of which are given in the appended claims.

The invention will now be described in more detail with reference to the accompanying drawings, in which:

Figure 1 shows a side view of one embodiment of the invention and Figure 2 shows another embodiment of the invention.

According to the invention, the principle by which heat is released to the environment is irrelevant. Such principles may include, for example, the use of lamella structures around the tubes or the use of different sheet surfaces for heat transfer 15, or combinations thereof.

Fig. 1 shows a heating coil 1 having a housing 2 within which heat supply and release devices are located. Housing 2 is of a type that ensures that the air is well circulated and absorbed heat.

The basic idea of the invention is that the radiator contains two different water circulation possibilities.

* ···· K ·:. Thus, the first cycle consists of the inlet and outlet pipes 3 and 4 and the second counterpart · ·:: T: 25 sections 5 and 6. Usually these are the ends of one pipe loop.

Suitable convection parts are attached to the tube loops, such as, for example, the tubes ··· • · · '.Vi in close contact with the lamellae 7, 8, generally shown in this figure as blocks. The purpose is to lead to a second cycle, eg, 3.4 operating ··· * · water circulation and another 5.6 to the ordinary radiator mains water.

Thus, according to the invention, for example, heating of a washroom or sauna is provided with both a hot water circulation and a radiator water supply. Because the temperature of the water in the water circulation depends on the outdoor temperature, but the water temperature in the domestic water cycle is mostly constant, during the cold period when the above mentioned legionella bacterial growth is a particular problem, the water correspondingly the temperature remains at a higher level.

10 This avoids problems caused by too low 'return water temperature' in a way that generates very little additional cost during the construction phase and does not require any special expertise or special tools. In summer, when the temperature is not due to the need for lower heat, the problem can be to completely shut off the coil circulation. Of course, closing should also be done if no heat is supplied to the radiator circuit.

In the above pictures, the positions of the different rotations are sequential. However, it is clear that the heat-absorbing parts of different circulatory systems can be equally or parallel to one another and their heat transfer ability may be affected.
