The invention relates to hydronym or radiant panel heating systems or cooling systems used for heating of residential and industrial premises. They can be used in the heating system or cooling floor as in Autonomous systems for thermal regime of different heat sources, and in the Central heating system.

In currently known hydronic systems panel floor heating uses a metal or plastic tubing embedded in the concrete slab along with attached by various means aluminiowymi plates (application SE No. 00/01789, CL F24D 3/14, publ. 15.09.2000).

Known floor heating system (patent of Russia №2242680, CL F24D 3/12, publ. 2004), containing the supply and return piping and heating panels, in the form of two rectangular plates, installed in parallel opposite each other. In the gap between them are supporting elements and two flow nozzles arranged in two diametrically opposite corners of the two plates, the connecting elements for connection flow pipe adjacent the heating panels to provide a continuous flow of heating fluid through the heating panel. In addition, the system contains a dispersing element, on th the th corresponding flow pipe and carrying out the dispersion of the heating fluid medium.

Closest to the proposed invention is a system of heating or cooling elements of a floor consisting of the supply and return piping and panels, each of which has a surface with grooves, in which are incorporated a hollow tube with an internal energy source, and the grooves are arranged in such a way that allow you to join these panels together in various configurations. Each panel is attached heat-conductive sheet forming a heat-conductive surface (application Rossi No. 2002118767/06, F24D 3/12, publ. 2002).

In known systems, which is the traditional, to maintain a constant floor temperature requires a significant amount of coolant circulating in the pipes, and therefore a significant cost for fuel and energy. Due to the large thermal mass and/or heat resistance of modern systems are usually very slow to respond to changing heat loads. Warm-up time changes in hours and even days.

In addition, known systems are also usually very different from each other constructions and are, as a rule, on the ground. Due to the large weight of the panels they often require additional costs and design solutions. Their installation is very time consuming and can be performed only by specialists. When this pipeline is hidden for workers, zanim is relating to the flooring floor coverings, not surprisingly, if it can be damaged pipe. In case of damage to the pipe from damage hard to find and therefore often necessary to remove a considerable part of flooring panels.

The objective of the invention is to provide highly effective system cooling or heating of a floor, used for heating of residential and industrial premises.

The technical result - the reduction of the volume of fluid and, accordingly, decrease the cost of fuel and energy, reducing the heating time and, accordingly, the response time to changing heat loads, simplifying the system design and its operation.

The technical result is achieved by the fact that the floor heating system of residential and industrial premises includes the supply and return pipelines and transmission medium heat, arranged in equidistant apart parallel grooves in the upper surface of the heating panels, over which is laid thermally conductive surface. In the grooves of the heating panels as a means of transferring thermal energy Packed set of jet-pipes, made in the form of a separate metal hermetically sealed buildings with areas of evaporation and condensation in the internal cavity of which is under vacuum pumped liquid conductivity. Each of these pipes is connected to supply the pipeline at an angle of 2-3° relative to the base of the heating panels.

In the proposed heating system reducing the volume of fluid and, accordingly, decrease the cost of fuel and energy is achieved by introducing into the heating system of the jet-pipe is hermetically sealed metal housing with zones of evaporation and condensation inside which is under vacuum pumped liquid heat conductor, with superconductivity. Under the influence of temperature on the evaporation zone, located on the side of the feed connection of the heat, it heats up quickly and produces a vapor. This steam, reaching the condensation zone, located opposite the cold side pipe, condenses and slope flows back to the evaporation zone.

Thus, when the heating set jet pipes arranged in parallel, and equidistant from each other, one end of which is located together with feed conduits at one side of the room, you can instantly get the heat on their other end, and the investigator and in the opposite side of the room.

The applicant has conducted a number of experiments on the comparison of the two heating systems - traditional systems and systems based on the principle of the jet-pipe.

The essence of the experiments consisted in the removal of various temperature, time, volume indicators, characterizing both systems. For this purpose we have selected two space dimensions 2×2×2 m and the points of temperature measurement. In one of these areas, the Underfloor heating system was done traditionally, and the other based on the principle of the jet-pipe.

In the first experiment in both areas have established an initial temperature of about 40°C. From this point with further increase in temperature every 10°C began to record the time and volume of water required to achieve it. The data obtained are shown in table 1.

In the second experiment also established certain temperature in both areas, the average value of which was approximately 50°. Then within 30 minutes every minute at selected points measured temperature. After processing the received data brought averages in 1 minute. The results of this experiment are shown in table 2.

In the third experiment, the surface was heated to 31°C, and then within the hour fixed the floor temperature, fuel consumption, and energy. Data from this experiment are shown in table 3.

Analysis of the obtained data showed that the heating surface of the floor both systems to 31.1°C with the "jet pipe" spent significantly less time (difference - 18 minutes), less fuel (2 times smaller) and, of course, less energy (2.5 times less).

Figure 1 is a schematic heating through the jet-pipe and a traditional heating system of Fig 2; laying the jet-pipe, a top view; figure 3 - jet-pipe (cut), type A; 4 - jet-pipe, type C.

The system comprises a supply pipe 1 and the return pipe 2, through which coolant is circulated 3, for example hot water and a means of transferring thermal energy 4. It is represented as a set of jet-pipes 5, each of which has the form of a separate metal, hermetically sealed housings with 6 zones 7 and evaporation condensation 8, the internal chamber which is under vacuum pumped liquid heat conductor 9. Jet-pipes 5 arranged in equidistant apart parallel grooves 10 of the upper surface 11 of the heating panels 12 and connected to the inlet pipe 1 at an angle α equal to 2-3° relative to the base 13 of the heating panels 12. On top of the jet pipe 5 is laid thermally conductive surface 14.

The system works as follows.

On the supply pipe 1 carrier 3, for example hot water flows to the connected transmission medium heat 4 - set jet pipe 5. As the carrier 3 along the pipeline 1 he alternately touches one of the jet-pipe 5. In the contact zone of its metal hermetically sealed housing 6 connected to the pipe 1, is heated. Under the influence of the temperature of the liquid heat conductor 9, pumped under vacuum in the interior cavity of the housing 6 in the evaporation zone 7, heats up quickly and starts to evaporate. The resulting steam, filling the enclosure volume 6, flows into the condensation zone 8, there gives heat and condenses. The resulting condensate due to the slope formed by connecting the hermetically sealed casing 6 to the inlet pipe 1 at an angle α equal to the 2-3° relative to the base 13 of the heating panels 12, flows into the evaporation zone 7. The heated jet pipe 5, arranged in equidistant apart parallel grooves 10 are located in the upper surface 11 of the heating panels 12, begin to radiate heat to the heat-conducting surface 14.

Similarly, the proposed system will work in the case of floor cooling, only the coolant can be used, for example, cold water.

Thus, the proposed heating system using jet-pipes used in standalone systems provide thermal regime of different heat sources, and in the Central heating system, allows you to create a highly effective system cooling or heating of a floor, used for heating of residential and industrial premises. It reduces the volume of fluid and thus reduce the cost of fuel and energy, reduce heating time and, accordingly, the reaction time to changing heat loads, as well as to simplify the system design and its operation.
