Definitions

  • the present invention relates to a fuel-heated heat source according to the preamble of the main claim.
  • Such heat sources together with the associated circuits are known as so-called circulation water heaters, which can switch a flow connection via a priority switch valve to a heating branch containing radiators and to a domestic hot water tank which is set up separately.
  • boilers which are switched as required either to a central heating system or to a store, which is usually located next to them, via a priority switch valve.
  • fuel-heated heat sources have become known in such a way that they have the priority switch valve and a hot water heat exchanger which works according to the flow principle and which heats the hot water as it flows through. There is no hot water storage here.
  • the output of the fuel-heated heat source must be dimensioned relatively large in order to be able to supply the hot water required for bathing or showering in a correspondingly large throughput.
  • relatively small heat sources can come into play if one takes into account a correspondingly long charging time for the associated store. If the heat source is dimensioned relatively large with regard to the storage capacity, there are high operational readiness losses since the heat source works cyclically on the domestic hot water tank, the downtimes of the heat sources being lost times.
  • a boiler system has become known in which the actual boiler is connected in parallel to a service water storage tank in addition to a radiator-feeding branch and charges it.
  • a small flow water heater is provided, which is provided directly in the boiler and is heated by the boiler water to enable the hot water supply in a continuous process.
  • a three-way switch valve is available, which sends the cold, hot water to be heated, depending on the operating mode, either through the storage tank or through the flow heater. It is impossible to reheat a domestic hot water tank that has not yet been fully charged with the flow heater.
  • a domestic water heater has become known from LU-A-55362, which has a hot water heater and, with respect to the hot water network, a hot water tank lying parallel to it.
  • the parallel connection of the instantaneous water heater and the storage tank is due on the one hand to the supplying cold water network and on the other hand to a consumer line. If no hot water is drawn off, the boiler works on the instantaneous water heater, which in turn conveys the hot water heated in it via a circulating pump for charging the storage tank. If tap water is tapped, the tap water is only heated in the instantaneous water heater when the storage tank is below a first tap water flow rate; when it is exceeded, cold tap water flows both through the instantaneous water heater and through the storage tank to the consumer. This means that when there is a high demand for hot water, the instantaneous water heater and storage tank work in parallel. If the storage tank is inadequately heated, for example if a discharge has just been carried out shortly before, reheating the storage water is impossible.
  • a boiler system has become known in which a process water storage tank is first heated by the boiler water. If its temperature is not sufficient, a reheater downstream of the domestic hot water tank is put into operation, in which the water preheated by the boiler in the domestic hot water tank is brought to its final temperature.
  • an additional energy source such as gas burners, electrical heating resistors or steam heat exchangers.
  • the domestic water can be reheated, but this is purchased with the disadvantage that an additional heat source is required.
  • the present invention is based on the object of providing a hot water central heating system in which hot water can be kept ready and heated in a hot water tank and in which, if the hot water tank charging is inadequate in the hot water branch, a reheater is provided which manages without an additional energy source.
  • a heat source 1 consists of a heat exchanger 2 and a burner 3, which is fed via a fuel supply line 5 provided with a solenoid valve 4.
  • the heat exchanger 2 is supplied with circulation water from a heating / process water circuit via a return line 7 provided with a circulation pump 6.
  • a flow line 8 connects to the heat exchanger 2 and leads to a three-way valve 9, which is controlled by a servomotor 10, which is connected to a control unit 12 via line 11.
  • the three-way valve 9 which can only move to two discrete positions or also continuously intermediate positions, has two outputs 13 and 14, the output 14 leading to a heating branch 16 having a plurality of radiators 15 connected in parallel and / or in series, the return line 17 is provided with two junction points 18 and 19 and leads to an intake port 20 of the pump 6.
  • the output 13 is connected to a service water branch, which consists of a service water supply line 21, a service water flow-through heat exchanger 22, a three-way valve 23 as well as a connecting line 24 and a service water tank 25, to which a service water return line 26 is located connects, which leads via a backflow preventer 27 to the junction 18. From the three-way valve 23, which can assume end positions or continuous intermediate positions.
  • the three-way valve has two valve seats, which are formed both by the input of the line 28 and by the input of the intermediate line 24 and which are more or less closable by a valve closure member 29 which is actuated by a temperature expansion sensor 30 which is exposed to the temperature of the heating water immediately after it has left the process water heater 22 via a line 31.
  • the hot water supply of the fuel-heated heat source just described consists of a tap pipe 32 connected to a feeding water network, which leads into the interior 33 of the hot water tank 25.
  • the connection between the intermediate line 24 and the return line 26 represents a heat exchanger tube coil 34 in the interior 33 of the water heater storage.
  • a temperature sensor 35 which is connected to the control element 12 via a measuring line 36, projects into the interior 33 of the domestic water heater memory.
  • Tap water leaves the interior 33 of the hot water storage tank via a connecting line 37 which leads to a pipe coil 38 which passes through the hot water heater.
  • the pipe coil 38 is connected at its downstream end to a tap 39, in which a water switch 40 is arranged, which is connected to the control member 12 via a measuring line 41.
  • the outflow end 42 of the tap line is controlled by a point tap valve 43.
  • a temperature sensor 45 is connected to the control device via a measuring line 44, which is connected in the flow line 8 between the heat exchanger 2 and the three-way valve 9 operating as a priority switching valve.
  • a control line 46 leads from the control element 12 to the electric motor which drives the pump 6.
  • Another line 47 leads to a solenoid 48 of the solenoid valve 4.
  • the control element 12 is still connected via sensors, not shown, the outside temperature ⁇ yes, the room temperature, and also the temperature of the line 7 between the pump 6 and the heat exchanger 2. Size X s is also applied to the control element.
  • the water switch 40 registers a water flow and issues a corresponding command to the control element 12. This causes the priority switching valve 9 to be switched over to the hot water heater branch.
  • cold hot water flows from the supplying water network via the Line 32 into the interior 33 of the water heater memory 25.
  • the water heater memory begins to discharge. Since the hot water storage tank still has the maximum storage temperature in its flow, there is initially no temperature difference in the flow heater 22 between the hot water and the heating water. In the course of the gradual discharge of the hot water heater memory 25, there is a temperature difference here, so that heat is also released from the hot water heater branch to the hot water via the instantaneous water heater 22.
  • the temperature of the heating water in the pipe 31 thus drops downstream of the instantaneous water heater 22, and the expansion temperature sensor 30 begins to move.
  • the more the temperature of the process water leaving the store via the line 37 drops the more the inlet of the intermediate line 24 in the three-way valve 23 is closed and the more the inlet of the line 28 is opened, that is to say that ultimately the fuel-heated heat source is no longer connected to the series connection of instantaneous water heater 22 and memory 25, but after completion of this state only to the instantaneous water heater. 22.
  • the first phase of the storage tank takes over the hot water supply, in a subsequent intermediate phase the storage tank provides the basic heating for the hot water, while the instantaneous water heater functions as a reheater and in the final phase only the instantaneous water heater takes over the hot water heating.
  • the process water request is ended by closing the nozzle 43, after the end temperature level has been reached in the flow heater 22 - which happens very quickly because no heat is extracted from the flow heater - the store 25 is recharged.
  • the priority switch valve 9 Based on a comparison of the measurement results of the temperature sensor 35 in comparison with its associated setpoint and the room temperature sensor, the priority switch valve 9 can assume intermediate positions, so that the memory is partially charged, but on the other hand heat is also partially supplied to the heating branch.
  • the fuel-heated heat source be it a gas boiler or oil-fired instantaneous water heater, is operated with relatively long operating times, which are necessary in order to supply sufficient thermal energy to both the space heating and the storage. This means that this heat source can be operated at maximum load and with very low efficiency at full load.
