Definitions

  • the invention relates to an air conditioning system for cooling and / or heating a building.
  • Air conditioning systems for cooling and / or heating a building are known from the prior art. Such systems typically have multiple circuits that perform different functions.
  • an air conditioning system includes a heating circuit for heating the building and a cooling circuit for cooling the building.
  • Such a system further comprises at least one refrigerant circuit that communicates thermally with the heating circuit and the cooling circuit.
  • a source / sink circuit is typically provided to enter thermal energy into the system for heating the building or to dissipate thermal energy from the system to implement the cooling function.
  • a further component of such systems can be a circuit that dissipates the excess thermal energy via a heat sink.
  • DE 202 16 324 U1 discloses a heat pump according to the preamble of claim 1, which is used to use a passive brine circuit with the ground as a heat sink for room cooling and to activate an active cooling process when there is a need for cooling that goes beyond this.
  • Heat pumps also disclose WO 03/074 953 A1 and US 4,727,727 A .
  • the invention has for its object to provide a simple and inexpensive air conditioning system that contributes to a reduction of a refrigerant to be used.
  • the air conditioning system for cooling and / or heating a building is disclosed.
  • the air conditioning system can also be referred to as an arrangement for cooling and / or heating a building.
  • the air conditioning system has a heat pump circuit, a heating circuit and an excess circuit.
  • the air conditioning system has a heat exchanger which is fluidly connected to the heat pump circuit, the heating circuit and the excess circuit at the same time.
  • the heat exchanger is integrated in three circuits at the same time, for example through which three separate circuits each have heat transfer media, heat energy that is transported in the heat pump circuit to the heat exchanger can be released via the heat exchanger to the heating circuit on the one hand and to the excess circuit on the other .
  • the heat transfer can take place during operation of both the heating circuit and the excess circuit at the same time.
  • two heat exchangers are not necessary, one of which is integrated in the heat pump circuit and the heating circuit and another heat exchanger in the heat pump circuit and the excess circuit.
  • the thermal energy of the heat pump circuit can optionally be delivered directly to one and / or two circuits.
  • the heat pump circuit has a refrigerant for the heat transport.
  • the heat pump cycle can also be referred to as a refrigerant cycle. Due to the heat exchanger described, refrigerant savings are made.
  • the heating circuit and the excess circuit each have water or a water-glycol mixture for heat transport.
  • a heat transport medium of the two circuits is water.
  • the heat exchanger has three channels, one channel in series with the heat pump circuit, one channel in series with the heating circuit and one channel in series with the excess circuit. This helps that the heat exchanger can be easily integrated into the three circuits described.
  • the way of fluidly connecting the channels to the respective circuits and using them inside the heat exchanger with different fluids makes it possible to provide only one heat exchanger instead of two heat exchangers in the air conditioning system.
  • the heat exchanger is a plate condenser which has three channels for connection to the heat pump circuit, the heating circuit and the excess circuit.
  • This construction of the heat exchanger results in an efficient separation between the various circuits described and thus enables the replacement of a further heat exchanger connected in series.
  • the channels are connected in the same way as above.
  • the heat exchanger is a dual heat exchanger or a dual condenser.
  • a dual heat exchanger or dual condenser is normally used to be integrated into two refrigerant circuits or heat pump circuits and one water circuit.
  • the heat exchanger with one refrigerant circuit and two fluidic circuits, in particular hydraulic circuits is used. The advantages described above are made possible in particular by this unusual use of the dual capacitor.
  • Another advantage of this condenser is that a heat transfer surface for the refrigerant circuit is enlarged compared to a normal condenser, which, for example, can reduce a condensation temperature and improve the efficiency or efficiency of the heat exchanger, for example by three to four percent.
  • the refrigerant charge capacity is reduced, for example up to 30 percent.
  • a refrigerant tank volume can thereby be reduced.
  • maintenance intervals can be reduced due to the F-Gas regulation, according to which, for example, leak tests have to be carried out.
  • Figure 1 shows an embodiment of an air conditioning system in a schematic overview.
  • the schematic overview of the air conditioning system can also be referred to as a pipe installation scheme.
  • the air conditioning system is used to heat and cool buildings and has several circuits that are directly or indirectly connected to each other, thermally or indirectly communicate with each other and are described below.
  • the air conditioning system can also be referred to as an arrangement for heating and / or cooling a building.
  • the air conditioning system 1 has a heating circuit 2, a heat pump with a heat pump circuit 3, an excess circuit 4, a source / sink circuit 5 and a cooling circuit 6. All of the circuits are thermally coupled to one another via heat exchangers and have pipelines through which a heat transport medium flows.
  • the source / sink circuit 5 is referred to below as the source circuit 5 for the sake of simplicity.
  • the heating circuit 2, the heat pump circuit 3 and the cooling circuit 6 are closed circuits which are not fluidly coupled to the other circuits mentioned.
  • the heating circuit 2 and the cooling circuit 6 have as Heat transport medium water, which flows through the pipes of these circuits.
  • the excess circuit 4, the cooling circuit 6 and / or the heating circuit 2 can have a water-glycol mixture as the heat transport medium.
  • the heat pump circuit 3 has a refrigerant as the heat transport medium, which is why the heat pump circuit 3 can also be referred to as a refrigerant circuit.
  • the heat pump circuit 3 is part of a heat pump, as will be described in more detail later.
  • the source circuit 5, the excess circuit 4, the heating circuit 2 and the cooling circuit 6 each have a pump P1 to P4, which are designed as circulation pumps and operate the circuits, for example to ensure a flow through the circuits.
  • the heat pump circuit 3 has a compressor 8, also called a compressor, which ensures the flow through this circuit.
  • the air conditioning system 1 has a first heat exchanger W1, which can be referred to as a cooling heat exchanger.
  • the first heat exchanger 1 is fluidly integrated into the cooling circuit 6 and the source circuit 5.
  • the first heat exchanger W1 is fluidly connected into the cooling circuit 6 and the source / sink circuit 5, so that heat transfer between these two circuits can be accomplished when the heat transport media of both circuits flow through the first heat exchanger W1.
  • the air conditioning system 1 has a second heat exchanger W2, which operates as an evaporator.
  • the second heat exchanger W2 is in the source circuit 5 and the heat pump circuit 3 switched so that, as above, heat transfer between the source circuit 5 and the heat pump circuit 3 is possible if both circuits are operated.
  • a third heat exchanger W3 is provided, which can also be referred to as a heating heat exchanger. This is fluidly connected to the heating circuit 2 and the heat pump circuit 3.
  • a fourth heat exchanger W4 which can also be referred to as an excess heat exchanger, is connected fluidically to the heat pump circuit 3 and the excess circuit 4, analogously to the above.
  • the air conditioning system 1 which in particular from the Figure 1 are to be derived are not explained with the exception of the following description.
  • one or more further circuits can be present.
  • the circuits described have several sub-circuits that can be switched depending on the need and control of the air conditioning system 1.
  • one or more valves are provided which switch different sub-circuits according to their position. Further details not described relate, for example, to sensors, sensors, control devices, pressure relief valves, expansion valves or the like.
  • thermal energy from a source 7, which can also act as a sink 7 is fed to the second heat exchanger 2 for evaporating the refrigerant of the heat pump circuit 3.
  • the source / sink 7 is geothermal energy in the exemplary embodiment.
  • Other sources and / or sinks are alternatively also conceivable, such as air, ice storage, recooling plants, groundwater, sewage, rivers, lakes or others.
  • the heat transport medium water or a water-glycol mixture of the source circuit 5 is fed with the aid of the pump P1 from the source 7 via a first valve 1 and a second valve V2 to the second heat exchanger W2, the first heat exchanger W1 not being flowed through . After flowing through the second heat exchanger W2, the fluid returns to the source or sink 7.
  • Thermal energy is supplied to the refrigerant of the heat pump circuit 3 via the second heat exchanger W2, so that the refrigerant can evaporate.
  • the evaporated refrigerant is fed to a compressor 8, in which the refrigerant is compressed.
  • the temperature and pressure of the refrigerant rise.
  • the refrigerant is fed further to the third heat exchanger W3, in which the thermal energy of the refrigerant is at least partially transferred to the heating circuit 2.
  • the third pump P3 is in operation, which circulates the water heat transfer medium of the heating circuit 2.
  • the refrigerant, which has given off the heat in the third heat exchanger W3, flows on to the fourth heat exchanger W4 and flows through it. Then the refrigerant via an expansion valve back to the second heat exchanger W2, where the process starts again.
  • a temperature of the source 7 is raised by the heat pump to a usable temperature level for the building and made available to the heating circuit 2 (with the required flow temperature)
  • the heat transport medium of the source circuit 5 circulates by actuating the pump P1 in a partial circuit, without flowing through the source / sink 7.
  • the heat transport medium flows to the first heat exchanger W1.
  • the heat transport medium flows via the second valve V2 to the second heat exchanger W2. The heat transport medium then flows back to the first valve V1.
  • the cooling circuit 6 is activated by the fourth pump P4 circulating the heat transfer medium. During cooling, the cooling circuit 6 absorbs heat from the building and releases it via the first heat exchanger 1 to the partial circuit of the source circuit 5 just described. This heat is emitted to the heat pump circuit 3, which is operated analogously to the above, via the second heat exchanger W2. In contrast to the heating operating mode, the heating circuit 2 is not actuated or operated, so that the heat cannot be given off to the heating circuit 2 via the heat exchanger 3. Rather, the thermal energy of the refrigerant is released to the excess circuit 4 via the fourth heat exchanger W4 and supplied to the source or sink 7. The source / sink 7 ultimately absorbs this thermal energy and can release it. In this case, the pump P2 of the excess circuit 4 is activated, which actuates the excess circuit 4 and allows the water or the water-glycol mixture to circulate.
  • a temperature level of the source / sink 7 is not sufficient for direct cooling operation (see below), so that a Heat pump operation is necessary and the source, such as geothermal energy, is used as a sink 7.
  • the heat pump circuit 3 is not in operation.
  • the heat of the cooling circuit 6 is given off via the first heat exchanger W1 to the source circuit 5, which is designed and switched as a partial circuit analogously to the above, such that the heat transport medium flows through the source / sink 7 as well as the first heat exchanger W1 and the second heat exchanger W2.
  • the thermal energy taken from the cooling circuit 6 is thus delivered to the source / sink 7.
  • source 7 is used as a sink.
  • a control system checks whether the temperature level of the source / sink 7 is sufficient for natural cooling. If this is the case, the cold obtained from the source 7 is made available directly to the cooling circuit 6 without the heat pump operating. If the source / sink 7 for natural cooling is exhausted, such as geothermal energy, the "cooling" mode described above is used.
  • the operating modes described above can also be used in combination so that, for example, part of the building can be heated and another part of the building can be cooled.
  • the source / sink circuit 5 is switched as a partial circuit so that the heat transport medium flows through both the source or sink 7 and the first heat exchanger W1 and the second heat exchanger W2.
  • the two cooling and heating circuits 2, 6 can be operated independently of one another. If heating and cooling are required at the same time, a check is carried out to determine whether there is a heat requirement or a supply of heat in the building. Depending on an energy balance and a temperature level of the source 7, this is used as a source or sink.
  • valves V1, V2 and / or other elements of the air conditioning system 1 can be automated via one or more control devices or regulating devices. Additionally or alternatively, all or some of the aforementioned elements can also be set manually.
  • the control devices have suitable means for making the desired settings.
  • the heat pump circuit 3 is fluidly coupled to three heat exchangers W2, W3 and W4.
  • FIG. 2 An embodiment of the invention is described, in which a dual condenser W5 is provided instead of the third and fourth heat exchangers W3, W4.
  • the air conditioning system 10 according to Figure 2 is essentially analogous to that based on Figure 1 described air conditioning system 1, with the difference that the fourth heat exchanger W4 for coupling with the excess circuit 4 is dispensed with.
  • the third heat exchanger W3 based on Figure 1 Air conditioning system 1 described is through the dual heat exchanger W5 replaced, which is a three-channel plate capacitor and can also be called a dual capacitor.
  • Such a dual heat exchanger W5 is normally intended for use with two refrigerant circuits and one water circuit.
  • dual condensers which can also be referred to as dual heat exchangers
  • two cooling circuits normally act on one water circuit (as a condenser and an evaporator version). In the event that less cooling capacity is required, a refrigeration cycle can simply be switched off.
  • this heat exchanger version also serves for operational safety, since 50% of the power is still available if a compressor fails.
  • the dual capacitor W5 which in Figure 3 is shown in perspective, exemplarily, has a plurality of coupled plates, which are crossed by three channels K1 to K3.
  • the dual condenser W5 is thus designed as a plate condenser and is used in an unusual manner in the air conditioning system 10 in such a way that the heat pump circuit 3 with the refrigerant is connected to the normally provided water channel, the second channel K2, and to the normally provided refrigerant circuit channels, the first and third channel K1 or K3, the heating circuit 2 and the excess circuit 4 are connected.
  • the plate capacitor structure separates the three channels.
  • the dual heat exchanger W5 can also be designed differently, in particular three channels K1 to K3 must be available.
  • the fourth heat exchanger W4 can be dispensed with as described above. With in other words, the fourth heat exchanger W4 is not connected in series. This enables the advantages mentioned at the outset. As a result, the heat pump circuit W3 can be significantly reduced, for example by 30 percent, with regard to a quantity of refrigerant and a pipe length. Furthermore, a reduction in the dimensions of the air conditioning system 1 as a whole or individual (sub) circuits and / or elements of the air conditioning system 1 is contributed.
  • the operating modes described above can be set in the same way as above.
  • the dual heat exchanger W5 is now flowed through by the refrigerant of the heat pump circuit 3, which can now give off heat to both the heating circuit 2 and / or the excess circuit 4, depending on whether one or both of the circuits 2 and 4 are operated by means of the pumps P3 and P2.
  • the air conditioning systems 1, 10 described may have further or differently constructed circuits. It is crucial here that the refrigerant circuit or heat pump circuit 3 is integrated in a dual condenser, which emits heat to two water circuits at the same time.
