Definitions
- the invention relates to an expansion tank according to the Genus of the main claim.
- the expansion vessel according to the invention with the characteristic Features of the main claim has the advantage that the Effectiveness and speed of heat exchange between the heating medium and the hot water is increased, which positively affects the performance / volume ratio of the Memory or the entire heater affects.
- the functional integration contributes significantly to a compact Construction of a heater for space heating and Domestic water heating at. This will improve the Domestic hot water comfort without significant volume increase of the heater reached.
- the heat exchanger with the coaxial line works in advantageously according to the countercurrent principle, since this Principle is the thermally most advantageous variant.
- the pipe coil Since the pipe coil is connected to a pipe network, it is necessary to make the pipe coil from pressure-resistant Train material. It is advantageous as a material Use copper because it is pressure resistant and high Has thermal conductivity.
- the coaxial line serves as a flow guide and between the inside and outside of the coaxial line flowing heating water only slight pressure differences exist, it is advantageous to the coaxial line and the Manufacture cuff from inexpensive plastic.
- the coil is ripped from the coaxial line spaced. Ribs and coil are more advantageous Can be made in one piece and both consist of one Material with a high coefficient of thermal conductivity. This will make the Heat transfer from heating to domestic water in advantageously further increased.
- the memory an elastic partition and a gas-filled one Chamber.
- FIG. 1 shows one in one Heating circuit arranged storage in a simplified form
- Figure 2 is an enlarged partial view of the memory in Section
- Figure 3 is a side view of the memory
- Figures 4 5, 6, 7 and 8 sectional views of coaxial Cables.
- FIG. 1 shows a memory 10 for domestic water heating in a piping system 12, 14 carrying heating water Heater.
- A arranged in the line system 12, 14 and through a burner 15 more exposed to combustion gases
- Primary heat exchanger 16 supplies the memory 10 via the Leading section 12 of this line system and via a Flow connection 12a of the memory 10 with heating water for the Domestic water heating.
- the return section 14 of the Line system leads from a return port 14a Storage 10 via a three-way valve 18 and one Heating water pump 20 back to the primary heat exchanger 16.
- the solid arrows indicate the Direction of flow of the heating water.
- the three-way valve 18 enables the supply of a with and Return connections 22, 24 indicated heating system with Heating water from the same heat source.
- the memory 10 is made by a method known per se loaded with heating water.
- a arranged in the memory 10 Temperature sensor measures the temperature of the Heating water in the storage tank, which is then fed through the heating water Primary heat exchanger 16 and by the hot water Line system 12, 14 is recharged when the temperature of the heating water drops below a certain value.
- a line 32 runs coaxially to that in the memory 10 lying pipe coil 26. This is one end of the coaxial line 32 as an open lying in the memory 10 End 34 formed, while the other end 36 with the Return section 14 of the heating water leading Line system 12, 14 is connected.
- the coaxial line 32 is just like the coil 26 in cross section circular and extends substantially over the entire length of the pipe coil 26.
- the pipe coil 26 and the coaxial line 32 are in the embodiment 1 designed as a single turn, where this essentially along an inner wall 38 of the Memory 10 extends.
- the one with the End 36 of the coaxial line 32 connected Return connection 14a a sleeve 40 with connecting piece 42, 44.
- the connecting piece 42 engages with a Inner wall 46 via an outer wall 48 of the coaxial line 32, while going out through an opening 50 in the store 10 guided connecting pieces 44 with an outer wall 52 opposite an inner wall 54 to the return connection 14a belonging sleeve 56 is completed.
- Over the sleeve 56 the connection with the return section 14 of the Line system 12, 14 manufactured.
- the cuff 40 has in addition, an opening 58 through which the Pipe coil 26 is led to the cold water connection 28.
- this is in the memory 10 arranged coil 26 and the coaxial line 32 as Double helix formed with two turns, making the Heat transfer surface, opposite the first Embodiment is enlarged.
- the memory 10 is still one with more elastic Membrane 60 formed partition, the one that Heating water leading housing half 62 from one Gas volume receiving housing half 64 separates. there have both housing halves 62, 64 circumferential at their ends Collar 66, 68, between which the membrane 60 with the help an annular bead 70 is clamped. The one between Membrane 60 and the housing half 64 forming space Nitrogen filled, which builds up a pressure cushion.
- the Housing half 62 is also provided with a connecting piece 72 provided for a quick breather through which in the heating water located oxygen can be excreted.
- the memory 10 operates in the following way:
- Heating water pump 20 located in the storage 10 heating water conveyed through the open end 34 of the coaxial line 32, being an increased heat exchange between that in the coaxial line 32 pumped heating water and in the pipe coil 26 flowing service water takes place.
- the heat exchange takes place in the counterflow principle, i. H. the cold water connection 28 and the hot water connection 30 of the Pipe coil 26 are selected so that in the pipe coil 26th flowing service water opposite to that in the coaxial line 32 pumped heating water flows, whereby the heat transfer factor is further improved.
- the final temperature of the in the coil 26 flowing hot water over the Final temperature of the flowing in the coaxial line 32 and cooling heating water can be increased.
- the coil 26 with a pressurized Pipeline network is connected and acts as a heat exchanger, it must be pressure-resistant on the one hand and made of a material that has good thermal conductivity having; therefore, as the material for the coil 26 preferably copper is used. Since the coaxial line 32 and the cuff 40 only as a flow guide for the Serve heating water, both can be made of plastic.
- FIGS. 4-8 show, around the coaxial line 32 from the coil 26 too are spaced between the two longitudinal webs 58 arranged which, as FIGS. 4-8 show, can be trained differently.
- Figure 4 shows a first Embodiment of webs 58 by a single Manufacturing process simultaneously with the production of the Pipe coil 26 can be produced from the pipe coil material are.
- 5 shows the coaxial line 32 and the webs 58 made in one piece, in Figure 6 are both coaxial Line 32, webs 58 and coil 26 in one piece educated.
- Figure 7 and Figure 8 show a fourth and fifth embodiment of webs 58 which are in the arrangement are modified, but from the production as the first three Embodiments can be produced.
