Definitions

  • the invention concerns a device for heating of water in water distribution lines of households and in water distribution lines in other residential or commercial objects.
  • Running hot water is one of the basic human needs.
  • the most common method used for heating of water is transformation of electric energy into heat which is then accumulated in heated water.
  • the transformation of electric energy into heat occurs particularly in resistance heating bodies that emit heat and the heat is transferred from the resistance heating bodies into water that covers their surface.
  • Resistance heating bodies consists in the fact that water is a poor heat conductor and therefore heat is not evenly distributed in a closed volume of water.
  • the heating resistance bodies must be distributed in the water in order to ensure that the surface of heating bodies covered with water is evenly represented in the entire volume of water, which is complicated not only from the viewpoint of design of the device for heating of water but also from the viewpoint of acquisition costs. Thanks to the local effect of heat on water on the surface of heating bodies the water often evaporates and minerals present in the water form deposits which means that the surface of the heating body is gradually covered with minerals and effectiveness of heat transfer from the body to the water is reduced. At the same time, if water is heated to temperatures close to the boiling point the released steam in the form of chaotic emissions may damage the device as a result of pressure changes or spraying of water into non-insulated parts.
  • Infrared radiation has been used for heating of water in a solution described in the patent application US 2002/0011482 (Al).
  • the subject matter of the invention is a water heater increasing temperature of water by means of infrared radiation emitted towards a water conduit.
  • the radiation is produced by a planar source consisting of carbon fibers embedded in polymer material with attached energized electrodes.
  • the water conduit is a meandering pipe situated in the proximity of the source of infrared radiation. Both the source of infrared radiation and the water conduits are enclosed in a box that forms a safe casing. The box is provided with thermal insulation to prevent heat losses of the flowing water.
  • the purpose of the invention is to create device that uses infrared radiation for heating of water, which would have a simple design and which would be efficient, resistant to damage and can be easily implemented in households and other facilities.
  • the outlined task has been resolved by creation of device for heating of water according to the following invention.
  • the device for heating of water with infrared radiation consists of a flow-through box and a source of infrared radiation situated inside the flow-through box, where the source of infrared radiation is at least one power-supplied panel or foil made of carbon fibers.
  • the summary of the invention consists in the fact that the source of infrared radiation is arranged in parallel with at least one planar heating body with flowing heated water, while the planar heating body is made of a solid infrared-absorbing material which surrounds a meandering, spiral-shaped or ribbed tubing inside the body.
  • the planar heating body can be made of a solid infrared-absorbing material with an internal porous structure forming a capillary system or a permeable system.
  • the planar heating body may be also filled with at least one type of granular infrared-absorbing material.
  • planar source of infrared radiation allows saving of space in the flow- through box.
  • the planar source emits radiation from its entire surface and therefore it is possible to arrange in parallel to it a planar heating body that absorbs the radiation also with its entire surface.
  • the carbon fibers have very good characteristics in terms of transformation of electric energy into infrared radiation, particularly high efficiency and long service life.
  • the advantage of infrared-absorbing materials consists in the fact that they do not reflect the radiation but transform it into heat. The whole volume of the planar heating body is heated while the heat is transferred by conduction into the tubing from which it is removed into the heated water. Nearly all radiation reaching the surface is absorbed and therefore there are no energy losses.
  • the heating body transfers the heat all along the tubing embedded in the material which is more efficient than classical resistance heating solutions. If the planar body is structured inside then the heated water flowing through it is divided into micro-volumes that can heat up more easily than a big volume of water with local heating effects. In big volumes the poor thermal conductivity of water is a significant obstacle to heating while in capillary or permeable systems the water is distributed and this shortcoming is eliminated. Also the employed grainy material absorbs infrared radiation and gets heated and then heats up the surrounding water. Again, the overall volume is divided into smaller parts which means more evenly distributed and more efficient heating. The grainy character also means low resistance to the flowing water.
  • the device for heating of water has a tube made of metal or plastic material.
  • metals demonstrate good formability, chemical stability and, particularly, excellent thermal conductivity while some plastics are also durable, chemically stable and cheaper than metals.
  • the device for heating of water according to the invention uses solid infrared-absorbing material or infrared-absorbing substance or infrared-absorbing material that is anhydride-based or anhydride with the chemical formula CaS0 4 .
  • one material or a combination of materials may be used from the group of brick clay, ceramics, sandstone, fireclay and plastic.
  • Anhydrides, particularly anhydride CaS0 4 have very good thermal conductivity and long service life and they are stable, workable, readily available and therefore also cheap.
  • the device for heating of water according to the invention has a planar flow-through box and it is provided with a frame to be set into the wall. The planar shape makes it possible to build it into standard walls and plasterboard partitions.
  • the device for heating of water has a separable frame which is provided with at least one means for dismountable installation of the flow-through box, while the flow-through box can be at least partly tilted out from the frame.
  • the box tilting is suitable for servicing operations. To take out the box from the frame or to make other manipulations with the box it is not necessary to disconnect the water conduit.
  • the frame is used to fix the flow-through box in the wall but the box must be set in the frame as dismountable or tilting out in order to enable servicing and maintenance operations.
  • the device for heating of water has an accumulation tank connected with the flow-through box via at least one water conduit.
  • the accumulation tank retains a sufficient reserve of heated water and therefore the device is able to supply hot water continually and can be used even in situations when short-term consumption of water is higher than the once-through capacity of planar heating bodies.
  • the device for heating of water has an accumulation tank connected with the flow-through box via an interconnecting water piping and recirculation water piping or the accumulation tank is provided with at least one means for moderate heating.
  • the accumulation tank is not possible to avoid thermal losses completely. Particularly at nighttime or during working hours consumption of water is very low and the water in the tanks cools down. To make sure that hot water is available at any time a recirculation system is in place which reheats the water continually or the means for moderate water reheating is activated.
  • the device for heating of water has an accumulation tank of a planar shape.
  • the planar shape is similar to the shape of the flow-through box so that also the accumulation tank can be built into walls and plasterboard partitions.
  • the device for heating of water has the inner volume of the flow-through box divided into at least two independent volumes and in each of them there is at least one source of infrared radiation and at least one planar heating body, while the independent volumes are coffer-arranged in the flow-through box.
  • the coffered arrangement makes it possible to regulate the output, to combine the heating contributions into the resulting flow of heated water and to increase efficiency and effectiveness of the device.
  • the device for heating of water has in the flow-through box coffer-arranged planar heating bodies connected with at least one internal water conduit and at least one control valve to regulate the flow of heated water in the internal conduit.
  • the control valves regulate the flow of water and thus regulate the output of hot water from the device.
  • the device for heating of water is provided with regulation electronics that control function of the sources of infrared radiation and the control valves.
  • the electronics uses software for easy setup of the output by the user. The user of the device can only set up the resulting value and the control electronics performs the device setup.
  • the control electronics is able to regulate the thermal output or the flow rate. Scenarios of activation of the individual sources and closing of internal conduits using the control valves, as contained in the control electronics, allow the device to work in a number of different regimes.
  • the device for heating of water has the source of infrared radiation connected to a photovoltaic source of electric power.
  • the combination of high efficiency of transformation of electric voltage into heat by means of infrared radiation and the renewable source of electric energy thus ensures low operating costs of such device for heating of water.
  • Such convenient versions with an accumulation tank enable to get over the night period.
  • the device for heating of water according to the invention features a very advantageous transformation of electric energy into heat using infrared radiation.
  • the transformation into heat is energy efficient.
  • the foil made of carbon fibers is space-saving and the heating bodies and the source of infrared radiation can be easily placed into a flow-through box the size of which allows its installation inside walls. The small depth of the box makes it possible to install the device even in restricted premises as the device takes up only little space.
