The invention concerns a method and means for heating rooms by using pipes with electrically heated water. More specifically, this invention relates to a method and device for heating rooms by using pipes with electrically heated water, in which a steam boiler for heating water and for circulation of hot water is not used, and electrically heating wire made of copper and having a diameter of 0.3-0.5 mm, is introduced into the pipe for the heated water through its entire length and thus would allow to warm a room by means of simple design and low energy costs without loss of thermal energy.

Usually the standard device, heating the floor of the room, includes teploizolyatsii consisting of pipes for hot water installed zigzag under the floor of the room, the heating means for the intense heat a certain quantity of water, feed means for supplying heated water in the pipe for the hot water so as to cause the hot water to circulate through the pipe for hot water. The heating means includes: a steam boiler having an electric heater or an oil nozzle, feeder and outlet fuel and purge air, and means for supplying hot water includes a circulating pump, a supply pipe that returns water pipe and valves.

In addition, it includes a water tank, expansion tank and regulating the temperature of the device.

In the standard method of heating the rooms with hot water, a large amount of water heated above means in a certain place. Then the heated water is forced evicted through the pipe circulation of hot water so that the pipe circulation of hot water radiates heat. The cooled water is returned to the heating ptx2">

In the standard device, the heating of the room is very large heat loss in the pipes located between the heating medium (steam boiler) and pipe circulation of hot water. In addition, compared with the radiating means (pipe circulation of hot water), the cost of the heating means and the feeding means is very high. Next, steam boiler (heating medium) shall occupy a separate room because of its bulkiness. In addition, the cost of maintenance of steam boiler is very high, and the use of the device of the heating room is inconvenient.

Known heating system of the building containing the pipe with water, in which is inserted an electrical heating elements (patent GB N 2193306, CL F 24 D 13/00).

In the system of radiators according to this patent uses a single line of the heating element from a material such as Nickel chrome, placed in a tube with a short length. In the known system heats the room by heating water by means of electrically heated wire placed in a limited space in the pipe, and then the circulation of heated water through the pipe by means of a pump. When this wire heating element of this type is of great with the TWT for heating rooms by using pipes with electrically heated water, in which the design is simple and effective and more economical.

The problem is solved in that in the method of heating the rooms, by heat transfer from an electrically heated water in the pipe, according to the invention heat the floor of the room by electricity through a copper wire placed along the length of the pipe with water.

The problem is solved also by the fact that the device for heating rooms containing tube with electrically heated water, according to the invention the pipe with hot water placed under the floor of the room in the form of a plane and provided with a copper wire that is installed inside the entire length, with copper wire made of electrically isolated and connected to line power, copper wire, is placed within and through the pipe with hot water, has a diameter of about 0.3 to 0.5 mm and a length of about 240-440 m

Copper wire inside and through the pipe with hot water, connected to line power in the insulated and waterproof condition, and the pipe from the hot water contains basic electrically heating wire and a lot of additional backup heating wires.

In this of which have complex structure, cumbersome to manage and expensive to maintain.

Due to the heating action of copper wire pipe from the hot water acts as a steam boiler, as well as the heater. Therefore, heating of rooms is carried out cost-effectively and without pollution.

However, in conventional homes, the length of the pipe with the heated water is several tens of meters or several hundred meters. If a wire of high electrical resistance (nichrome wire) is installed along the length, the value of its resistance is very high and, therefore, it is convenient to use copper wire, since it has low resistance.

The above objective and other advantages of this invention will become more apparent by describing in detail a preferred form of this invention with reference to the attached drawings, in which:

Fig. 1 illustrates a variant of the present invention, in which electrically heating the copper wire is placed within and through the whole length of the pipe for hot water and

where R is the resistance value, is the resistivity, L is the length (m) wire, and A is the cross-sectional area (mm2) wire.

That is, the thinner and longer the wire the greater the resistance of the wire. In other words, the resistance R is directly proportional to the length L (m) of the wire and inversely proportional to the cross-sectional area A (mm2). In other words, if you want to skip through a copper wire a certain amount of electric current, copper wire should have a given thickness.

In this invention, a copper wire placed across the pipe with hot water, attached to a small diameter in comparison with a standard diameter. Copper has a very low resistivity, but through the use of heat production due to the small cross-sectional area of the water that fills the pipe for hot water heated.

The diameter of the copper wire used as a heating wire (high resistance) in this invention is 0.3-0.5 mm, and its length is about 240-440 m the longer the wire, the greater its diameter. On the other hand, the shorter the length of the wire, the smaller its diameter: PA wire covered with enamel and even covered with a Teflon resin so the final thickness of the wire is equal to at least 1-2 mm.

The specific resistance of copper wire at normal temperature a little and 1.60 mcomm. However, the copper wire is very long and thin, and, therefore, copper wire, extending through the whole length of the pipe for hot water may generate sufficient heat energy to heat water thereby to heat the room.

Because copper wire has a very low resistivity compared to the nichrome wire, it can have a much smaller diameter compared to the nichrome wire.

The inside temperature of the room rises to approximately 20oC, and this temperature with heated water pipes should be only 40oC. This temperature can be achieved by filing a power of 220 V (voltage) x 3 (current) for about 30 minutes. Thus, the water is heated, and the radiation of heat from the pipe with hot water. Then, electric power is intermittently controlled by the controller to the desired temperature so that you can keep the room temperature constant. The formation heat of copper is sobienie there is almost no heat loss compared to standard technology, when water is heated in a steam boiler to 70-80oC, to maintain the pipes with hot water at 40oC. Thus, in this invention the degree of heat recovery is very high and, consequently, the energy input for heating the rooms are smaller than standard technology.

Further, the present invention heats the water in the pipe for hot water and at the same time heated room. Therefore, even when the power source is disconnected intermittently, high temperature pipe with the heated water is maintained considerable time due to residual heat. Therefore, the power consumption is saved, and the room temperature is maintained at a stable level.

In addition, the present invention provides not only the simplification of the device of the heating room and usability, but also eliminated such expensive components, such as steam boiler, burner, blower, circulation pump, and the like. Further, the space for installation of a steam boiler is eliminated, and the costs of running and maintaining a very significantly reduced. In addition, environmental pollution due to exhaust gas produced and spilt fuel can be pragotrade water can be made in the form of a zigzag like a standard technology, but more preferably, a pipe for hot water was installed in a spiral form. The reason is the following. The pipe with the heated water has a heating function and a transmitting function, and therefore, if the bending angle of the pipe with hot water smoother, it is possible to avoid the phenomenon of concentration temperature. Further, after installation of the pipe with hot water replacement is easy.

In addition, additional heating wire is installed along with the main heating wire so that this additional heating wire can be used when the main fault of the heating wire. Teflon resin, which covers the copper wire must have high heat resistance. However, the temperature of the heating is low, and therefore excluded the possibility that the resin is melted or leaking electricity.

Fig. 1 illustrates a variant of the present invention, and Fig. 2 illustrates a portion of A Fig. 1 in an enlarged scale.

Copper CU wire having a diameter of 0.35 mm, covered with a layer of enamel EN, and then covered with a layer of Teflon resin DF. Thus, the copper wire is securely isolated, and so many who ablaut in the pipe 2 for hot water having an inner diameter of about 8-10 mm, so that the composite wire stretched across the length of the pipe 2 for the hot water.

Then, as shown in Fig. 1, 240 meters of pipe 2 for the hot water concentrically set in the form of a rectangular spiral with an interval of about 10 - 30 see Both ends of the pipe for the hot water is connected through the device 5 water supply from the water tank 4 mounted higher above the floor.

Further, both ends a and b are electrically heating wire 1, projecting beyond both ends of the pipe 2 with hot water, connected with the energy line 1'. This United side brazed by means of adhesive elements 6 so that the United parts were insulated and waterproof. Electric power lines 1' conduct to the outside of the device 5 water supply thus to bring them to the device 7 temperature control. Each pair of power lines 1' supplied with the switch S or S' and any pair is used as a line of heating, while the other pair is reserved as an additional line. This additional line is in effect, if the current line heating is interrupted.

The water supplied from the water tank 4 into the pipe 2 for hot water and air is e above). The water tank 4 is open to the outer air so that the water level may shift in the natural course. The temperature sensor 7 provided with a device bk lock electrical leakage control lamp pr and handle ts temperature control.

If the switch is closed for receiving commercial power 220 V, line 1 electric heating installed inside the pipe 2 for the hot water slowly heats up. Thus, after about 30 minutes the water in the pipe for the hot water is heated to approximately 40oC. Then, if the device temperature adjustment set at the correct temperature, the temperature rise above a predetermined level is delayed so that the room temperature was maintained at the appropriate level.

According to this invention, as described above, a thin heating wire is placed within and across the pipe for hot water installed under the floor in the shape of a plane. Thus, the floor is heated by electricity through a copper wire and by heating the water inside the pipe for hot water. Thus, the pipe with the heated water is heating and radiating device is a rotary tool supply is fixed, so the design of the heating means of the room is extremely easy. Further, the intervals between the individual heating means and means for supplying also eliminated for convenience.

In addition, the temperature distribution above the floor is uniform, and the degree of heat recovery improved. Then saved the cost of installing such means as the heating means, and means for supplying heated water, while the cost of operation and maintenance is also reduced. When using nighttime electricity maintenance total cost of heating the room will be significantly reduced.

In addition, due to the simple structure and ease of control, heated room becomes more convenient.
