- Fig. 12 shows a device for obtaining heat in accordance with the invention in an embodiment.
- device 1 for obtaining heat comprises in each embodiment a first brine circuit 2 with a first brine pump 3, as well as a heat pump unit 40 with a heat pump 4 and an outside register 5 which is subjected to ambient air via a fan 6.
- a second brine circuit 7 is provided with solar collectors 8 and a second brine pump 9, with said second brine circuit 7 being thermally connected with the bottom zone 10 of heat storage reservoir 11.
- the heat storage reservoir 11 comprises a total of three vertically stratified zones which are separated from each other by perforated plates for example, with a middle zone 12 being adjacent to a bottom zone 10 and an upper zone 13 being adjacent to the middle zone.
- the middle zone 12 of the heat storage reservoir 11 is connected with a heating circuit 14 for heating a building 15.
- Reference numeral 16 indicates a circulating pump of the heating circuit 14.
- the temperature in the heating circuit is set via a mixing valve 17 and a temperature sensor 18.
- Device 1 further comprises a hot water conditioning circuit 19 with a circulating pump 20, with the hot water conditioning circuit 19 originating from the upper zone 13 of the heat storage reservoir 11 and opening into the bottom zone 10 of the heat storage reservoir 11.
- the hot water conditioning circuit 19 is thermally connected with a fresh water module 21 whose fresh water inlets and outlets are designated with reference numerals 22 and 23.
- the pumps 3, 9 and 16 can be arranged with variable speed.
- the first and second brine circuit 2, 7 are filled with a brine, e.g. with glycol.
- the heating circuit 14 and the hot water conditioning circuit 19 on the other hand are filled with heating water.
- the first brine circuit 2 can be flow-connected with the second brine circuit 7 via a first valve 24 arranged as a mixing valve.
- the heating circuit 14 can be connected with the hot water conditioning circuit 19 via a second valve 25, e.g. a switching valve, and a connecting line 25a.
- Reference numerals 26 indicate further temperature sensors.
- the formation of condensation water in the solar collector 8 at low ambient temperatures can be prevented for example in such a way that the second brine circuit 7 is heated by the first brine circuit 2 with the heat pump unit 40 and the outside register 5.
- the large variability in the possibilities for switching and operating states is obtained especially in such a way that the heat sources of solar and ambient air can be utilized both in a serial manner as well as independent from each other.
- the heat pump unit 40 is deactivated.
- the second brine circuit 7 is separated from the first brine circuit 2 by the first valve 24. Heat is supplied to the heat storage reservoir 11 via the second brine circuit 7, with the heat of the heat storage reservoir 11 being supplied to the heating circuit 14 and/or the heat water conditioning circuit 19. The energy is obtained on the one hand via the heating circuit 14 and on the other hand via the fresh water module 21.
- the connecting line 25a between the heating circuit 14 and the hot water conditioning circuit 19 is deactivated.
- the desired temperature in the heating circuit 14 can be set via the mixing valve 17 and the temperature sensor 18.
- This state occurs when on the one hand there is insufficient solar input and on the other hand the bottom zone 10 of the heat storage reservoir 11 is not at a sufficiently high temperature level.
- the outside register is operated in this operating state and the heat generated by the heat pump unit 40 is supplied directly to the heating circuit 14.
- the return of the heating circuit 14 is guided via the middle zone 12 of the heat storage reservoir 11, so that the heat stored therein can be utilized.
- the second brine circuit 7 with the solar collectors 8 is in operation, as is indicated by the broken lines.
- the hot water conditioning circuit 19 can be activated or deactivated, as required.
- the retrieval of fresh water via the fresh water module 21 is possible at any time.
- the connecting line 25a is deactivated via the valve 25.
- the first valve 24 interrupts the connection to the second brine circuit 7 and only releases the path to the outside register 5.
- the outside register 5 is used for generating heat.
- the outside register 5 is in operation and withdraws heat from the ambient air. It is supplied via the heat pump unit 4 to the heating circuit 14.
- the connecting line 25a to the hot water conditioning circuit 19 is activated via valve 25, so that the medium of the heating circuit 14 is not guided to the line branch leading to the building 15, but via the connecting line 25a to the upper zone 13 of the heat storage reservoir 11. This leads to a direct heating of the upper zone 13 of the heat storage reservoir, through which hot water can be withdrawn very quickly from the fresh water module 21.
- the connection between the first brine circuit 2 and the second brine circuit 7 is interrupted through the first valve 24.
- first and second brine circuit 2, 7 This concerns a combined operation of first and second brine circuit 2, 7 and the heat storage reservoir 11.
- Energy is withdrawn from the ambient air primarily by means of the outside register 5.
- the first valve 24 is controlled in such a way that exactly so much energy reaches the second brine circuit 7 via the brine as can be taken "passively" from the heat storage reservoir 11 by means of the speed-controlled pump 9 of the second brine circuit 7, so that the solar collector 8 is not operated beneath the ambient temperature.
- condensation in the solar collector 8 is avoided.
- the upper zone 13 can be reloaded for hot water conditioning in operating state 4, in analogy to operating state 3.
- This operating state substantially corresponds to the operating state 4, with the difference that the heating circuit 14 is supplied with energy.
- the connecting line 25a is deactivated via the valve 25 and is switched to the heating path 14a leading to the building 15.
- Fig. 7 shows an embodiment as an alternative to the operating states 4 and 5, in which the middle zone 12 of the heat storage reservoir 11 is supplied with energy.
- the heating circuit 14 is bridged via a bypass line 28 by means of valve 25, so that the heating medium is not supplied to the building 15, but directly to the heat storage reservoir 11.
- the second brine circuit 7 is operated without any admixing from the heat storage reservoir 11. It is relevant in this respect that the temperature in the line of the brine circuit 7 to the solar collector 8 does not exceed a threshold fixed in a controller (not shown). Heat is supplied to the heating circuit 14 via the heat pump unit 40.
- the state of defrosting occurs when too much ice forms on the outside register 5. Then it needs to be defrosted. This occurs in the present case by means of energy disposed in the heat storage reservoir 11. In this process, a compressor (not shown) as well as the fan 6 of the outside register 5 are switched off. The brine which is pumped to the outside register 5 is adjusted to approximately 15°.
- the present device 1 offers the possibility to discharge heat via the outside register 5 to the ambient environment. Protection from burning is important, so that the maximum temperature of the heat exchanger in the outside register 5 is set to 40° or 5° to 10° over the ambient temperature.
- the precondition is that sufficient energy is present in the heat storage reservoir 11, so that the heat pump unit 4 can be provided with energy for the heating circuit 14. This occurs for such a time until the heating room temperature plus a predetermined distance has been reached. Since the energy which is contained in the bottom zone 10 of the heat storage reservoir 11 is originated predominately by solar input, the efficiency of the overall system of device 1 can be increased substantially by this measure.
- This mode occurs in analogy to the operating state 9, with the difference that it is not the heating system that is thermally loaded, but the upper zone 13 of the heat storage reservoir 11.
- the connecting line 25a is activated by the valve 25.
- Fig. 12 shows a device which is suitable for extended defrosting. Depending on the actual solar radiation it may occur that effective defrosting of the outside register 5 with solar power is not possible or advisable. Heat can be withdrawn from the heat storage reservoir 11 by means of the heat exchanger 27 of the second brine circuit 7 and be supplied to the first brine circuit 2 and thus the outside register 5. If the heat stored in the heat storage reservoir 11 is too low, then this measure is also not sufficient for effective defrosting of the outside register 5.
- the heating circuit 14 is connected with the bottom zone 10 of the heat storage reservoir 11 via the second valve 25 and the connecting line 28, with the connecting line 28 opening into the heat storage reservoir 11 via a nozzle 29 facing the heat exchanger 27 of the second brine circuit 7.
- the thus occurring turbulent flow of the incoming heating medium heats the heat exchanger 27 formed by the heating coils and thus the brine of the second brine circuit 7 circulating therein, and subsequently the outside register 5 via the first brine circuit 2.
