Definitions
- the invention relates to a heat pump system according to the preamble of claim 1.
- a heat pump system of the type mentioned at the outset is generally known, so that no special printed documents are required.
- a heat pump system 10 consists of a heat pump (also called monoblock heat pump) arranged outside a building with a heat pump circuit for a circulated heat pump circuit medium, a heat exchanger 15 through which the heat pump circuit medium flows on the one hand and a heating circuit medium on the other, and a heating circuit for the circulated heating circuit medium.
- a heat pump also called monoblock heat pump
- the invention is based on the object of improving a heat pump system of the type mentioned at the beginning.
- a heat pump system that can be used more flexibly is to be created.
- a bypass device is provided on the heating circuit which, if necessary, decouples the heat exchanger, ensures further circulation of the heating circuit medium in the heating circuit and is arranged inside the building. 5
- the heat pump system according to the invention is characterized in that the heating circuit is designed to be operable even when the heat pump circuit is decoupled or not yet connected, which is particularly advantageous when the heat pump system has not yet been installed or when the heat pump is being serviced.
- a preferably electrical heating device acting on the heating circuit medium is particularly preferably provided in addition to the heat exchanger, so that the system can at least temporarily also be operated completely without the heat pump itself.
- a device for the provision of thermal energy is known from the document AT 12588 Ul, in which, for example, a swimming pool can be supplied with thermal energy with the aid of a solar absorber and a heat pump.
- FIG. 1 shows a heat pump system with the bypass device according to the invention
- FIG. 2 shows a first, particularly simple embodiment of the bypass device according to FIG. 1; 25th
- FIG. 3 shows a second, particularly elegant embodiment of the bypass device according to FIG. 1 in a first position
- FIG. 4 shows the second embodiment of the bypass device according to FIG. 3 in a second position.
- the heat pump system shown in Figure 1 initially consists in a known manner of a heat pump 1 arranged outside a building with a heat pump circuit 2 for a circulated heat pump circuit medium, a heat exchanger 3 through which the heat pump circuit medium flows on the one hand and a heating circuit medium on the other hand, and a heating circuit 4 for the circulated heating circuit medium (typical water).
- the heating circuit 4 has a flow line 4.1 and a return line 4.2.
- the heat pump 1 is arranged in a housing 1.1.
- a bypass device 5 is provided on the heating circuit 4, which decouples the heat exchanger 3 if required, ensures further circulation of the heating circuit medium in the heating circuit 1 and is arranged inside the building.
- the presence of the bypass device 5 according to the invention is advantageous, for example, if the heat pump 1 is to be serviced at another location (for example in the heating installer's workshop).
- the heating circuit medium flows through the heat exchanger 3 in a (first) operating mode.
- provision is also made for the heating circuit medium to flow through the heat exchanger 3 is prevented in a second operating mode with the aid of the bypass device 5.
- the figures show the heat pump system according to the invention schematically.
- the figures should not imply that the heat exchanger 3 flows through in the embodiment according to FIG. 2 in countercurrent and in the embodiment according to FIGS. 3 and 4 in cocurrent to the heat pump circuit will.
- the actual direction of flow can also be reversed in each case; this is determined by the person skilled in the art depending on the requirements in each individual case.
- the bypass device 5 can also be helpful during the construction of the building and before the assembly of the heat pump 1, since in this way the heating device 7, which is particularly preferably designed optionally as an electrical heater, in particular a flow heater, and / or as a heat exchanger belonging to a solar thermal system, screed drying can be carried out.
- the heat pump 1 as a monoblock heat pump, is arranged outside the building and the bypass device 5 is arranged inside the building 25.
- bypass device 5 considered somewhat more precisely (and this ultimately applies to all the embodiments shown), it is particularly preferably provided that this one between the feed line 4.1 and the Has return line 4.2 arranged and flow-controllable bypass line 5.2 via at least one valve 5.1.
- the flow line 4.1 via a first and second flow line connection 4.1.1, 4.1.2 and the return line 4.2 via a first and second return line connection 4.2.1, 4.2.2 with the bypass device 5 hydraulically connected is formed.
- a three-way switch valve 5.1 and a bypass line 5.2 arranged between the two lines or valves are simply provided on both the flow line 4.1 and the return line 4.2.
- the heating circuit medium thus either flows from the first flow line connection 4.1.1 to the second flow line connection 4.1.2 or from the second return line connection 4.2.2 to the first return line connection 4.2.1 or it flows from the first flow line connection 4.1.1 directly to the first return line connection 4.2.1 .
- the bypass device 5 is particularly preferably designed as a 4/2-way valve.
- the bypass line 5.2 is preferably arranged at least partially in the valve itself.
- the 4/2-way valve can be used, but does not have to, preferably provided that in a first position of the bypass device 5, the first flow line connection 4.1.1 with the second flow line connection 4.1.2 and the first return line connection 4.2 .1 is designed to be hydraulically connected to the second return line connection 4.2.2.
- This first position corresponds to the aforementioned first mode of operation.
- the first flow line connection 4.1.1 15 is designed to be hydraulically connected to the first return line connection 4.2.1. Whether the second return line connection 4.2.2 is connected to the second flow line connection 4.1.2 or not, as shown in FIG .
- either the flow line 4.1 and / or the return line 4.2 have a plug connection 4.3, preferably without tools, between the bypass device 5 and the heat exchanger 3.
- plug-in connection is, as is readily apparent, to be understood in principle as any connection or connection device that can be detached without being destroyed.
- an electrical line connected to the heat pump 1, optionally provided for power and / or information transmission has a plug-in connection 6 that can be detached preferably without tools.
- plug connection 4.3 and / or the plug connection 6 are or is accessible from the outside on the housing 1.1 of the heat pump 1.
- bypass device 5 is designed to be connected to a control device 9 of the heat pump system either to detect and / or to influence its position setting.
- either the plug connection 4.3 and / or the plug connection 6 has a status sensor 9.1 connected to the control device 9, which is preferably arranged outside the housing 1.1 or in particular in the building, so that the control device 9 is informed about it whether the connector 4.3 or 6 is connected or not.
- the heating circuit 4 is designed to be provided with a refilling device 8 for the heating circuit medium. This requirement ensures - in terms of the method - that after a change from the second to the first mode of operation, a fill level of the heating circuit medium in the heating circuit 4 is determined and, if required, heating circuit medium can or will be automatically topped up with a refill device 8.
- the heat pump system according to the invention works (based on Figures 1 to 4) as follows:
- the valve 5.1 of the bypass device 5 is switched in such a way that the first and the second flow line connection 4.1.1, 4.1.2 are fluidically connected to one another.
- the first and the second return line connection 4.2.1, 4.2.2 are also fluidically connected to one another.
- the heating circuit medium circulated in the heating circuit 4 is heated at the heat exchanger 3 of the heat pump 1 and the heat is given off again via the heating element 10 to the building.
- the valve or the valves 5.1 in the case of the embodiment according to FIG 4.1.1 is connected to the first return line connection 4.2.1 via the bypass line 5.2. As a result, no more heating circuit medium flows through the heat exchanger 3.
- heating circuit medium (as mentioned: unproblematic water) leaked out of the flow or return line 4.1, 4.2, the missing amount of heating circuit medium in the heating circuit 4 can now pass through the refilling device 8 can be compensated (preferably automatically).
