DE2364598A1 - Floor heating using hot water or air - has flow passages of linked channels adjacent to each other - Google Patents

Abstract

A box structure is placed immediately below the finished floor surface. It has inlet and outlet connections for the heating medium which may be hot water or warm air, and is divided internally by vertical partitions into a series of channels. The width of the channels is such as to give an adequate velocity of the heating medium. There are no gaps between the channels so that the whole floor area becomes heating surface and consequently the structure can be made shallow enough to be added to the floors of existing buildings. The efficiency is also improved. Layers of insulating material are placed beneath the box to prevent heat loss downwards.

Floor heating for residential and open spaces.

Floor heating systems are installed with success because they are economical to operate, even if they are expensive to install. However, the problem is the relatively high height of 50-70. mm, which makes retrofitting in existing apartments difficult, if not impossible. It has now been found that floor heating using specially developed elements with an overall height of only about 20 mm can be carried out advantageously and, moreover, operated more economically than was previously the case, which is particularly important because of the general scarcity of energy.

In contrast to the well-known underfloor heating, which consists of individually laid pipe coils exist, according to the invention, an arbitrarily long and wide, honeycomb structure (heat exchanger) made of metal and / or plastic, according to Fig. 1, through which the heating medium, for example water or air, is sent. The heating medium flows evenly through the heat exchanger, in which it enters at one end and exits at the other end. The evenness is made possible by the deflections, which are opposite to bent pipes are tension-free and thus the greatest possible security against the special the cracks that occur in plastic pipes. As a clear measure using the dimension of 10x10 mm with a wall thickness of 1 mm Proven from polyethylene, although other dimensions, such as 10 χ 20 mound others bring a very good result. As insulation against heat loss, the heat exchanger according to Fig. 1 below can be covered with an aluminum foil, 3, and / or an insulating compound 4, for example foam, can be provided. Compared to the known floor heating with pipes, that according to the invention is implemented Arrangement is more economical because it can be laid considerably faster, i.e. in the manner of a carpet, and offers a maximum surface area. From above we see the heat exchanger covered in a known way with screed. Because of the large surface you can keep the temperature of the heating medium low and still use the

achieve the desired heating effect. The temperature of the heating medium can then for example plus 25 C. At this moment it is then possible in addition to the usual heating sources such as oil, gas or coal, to use heat pumps that generate a large part of the heat from groundwater, soil and obtain other suitable heat sources, which can save a considerable amount of fossil fuels. So it has been shown that underfloor heating around 50% fossil energy using a classic heat pump saves, namely the amount that you get from the groundwater in terms of calories or earth or other sources. The heat pump only works then

ο economical, if it does not require temperatures above 40 c.

In the case of the floor heating according to the invention, this is because of the extremely large surface the case.

Fig. 2 shows another embodiment of the floor heating according to the invention below Use of a double or multiple register, one-sided inflow and outflow and / or Rujldprofil. ... "-. ' .

Fig. 3 shows another embodiment in which the reflux is arranged parallel to the inflow. This enables a uniform temperature across the entire heat exchanger, since the hot strand comes to rest next to the cooled, cold strand. - Fig. 3 also shows an arrangement characterized in that stiffeners (1), consisting for example of sheet steel or wooden strips or concrete, are provided, which enable the heat exchanger to be loaded. Entire cutouts (2!) Can also be provided, namely where no heating is required, such as under cupboards and chests of drawers. The heat exchanger is covered from above with a stable, pressure-resistant plate (3), for example 1 mm glass fiber reinforced polyester, so that a body is created that can also be loaded by heavy furniture. Of course, the versions according to Fig. 1-3 can be individually, but also combined with one another and only represent a few options for execution.

The heat exchange .- ^ r know from metal and / or plastic -, · ^. can be produced using extrusion, compression or vacuum processes. Gas or water are preferably used for heat transport. The floor heating is suitable for houses, open spaces, streets, bridges, etc.

Should a duct be damaged during or after the installation of a heat exchanger become and thus leaky, this can be done mechanically or by heat and squeezing off without having to replace the entire system.
