  However, in the conventional heating apparatus, only high-temperature air obtained by the compression circuit is supplied to the room, so that there is a problem that it is difficult to adjust the temperature during heating and it is difficult to air-condition the room in a suitable state.

Moreover, based on the heat radiation performed by the first heat pump, a second heat pump or the like other than the first heat pump can further perform heat radiation. Therefore, a temperature difference occurs between the heat exchange medium that flows through the first circulation channel and the heat exchange medium that flows through the circulation channel such as the second circulation channel other than the first circulation channel. .

  That is, during cooling, the heat exchange medium such as the second circulation channel is at a lower temperature than the heat exchange medium in the first circulation channel. For this reason, it is possible to cool the room at a lower temperature in the second connection state than in the first connection state. Further, during heating, the heat exchange medium such as the second circulation channel is at a higher temperature than the heat exchange medium in the first circulation channel. For this reason, the second connection state can heat the room at a higher temperature than the first connection state.

  In this air conditioner, the first connection state and the second connection state can be switched by the switching means. For this reason, in this air conditioner, depending on the purpose, it is possible to selectively use the air conditioning in the first connection state and the air conditioning in the second connection state, and it is easy to adjust the temperature during air conditioning.

  Therefore, according to this air conditioner, the room can be suitably air-conditioned.

  As the heat pump, a chemical heat pump, a thermoelectric conversion module, a compression circuit, or the like can be employed. Moreover, the same thing can each be employ | adopted for each heat pump, and a mutually different thing can also be employ | adopted.

  The air conditioner of the present invention is not limited to the case where the number of heat pumps and circulation channels is two. For example, when the number of heat pumps is 3, three heat transfer units are provided, and when the number of circulation channels is 3, the first to third circulation channels can be provided. In this case, the first circulation passage is thermally connected to one heat transfer portion of the first heat pump, the other heat transfer portion of the second heat pump is thermally connected to the first circulation passage, The second circulation channel can be thermally connected to one heat transfer portion of the two heat pump. The other heat transfer unit of the third heat pump can be thermally connected to the second circulation channel, and the third circulation channel can be thermally connected to one heat transfer unit of the third heat pump. In this case, the state where the second circulation channel and the air conditioning heat exchanger are connected may be the second connection state, and the state where the third circulation channel and the air conditioning heat exchanger are connected is the second connection.

Furthermore, in the air conditioner of the present invention, the term “indoor” not only means an internal space in a building, but also broadly means an indoor space of a vehicle or the like.

(Claim 2). In this case, the air conditioner can be configured, for example, as shown in FIG. Hereinafter, the effect of this air conditioner will be described based on the air conditioner shown in FIG.

  This air conditioner includes a first heat pump 100, a second heat pump 101, a first circulation channel 102, a second circulation channel 103, an air conditioning heat exchanger 104, and branch valves 105a and 105b as switching means. And flow paths 108a, 108b, 109a, 109b, a heat radiation flow path 106, and a heat exchanger 107.

  The first circulation channel 102 is thermally connected to the first heat absorption unit 100a and is also thermally connected to the second heat dissipation unit 101b. The second circulation channel 103 is thermally connected to the second heat absorption part 101a. The heat radiating channel 106 is thermally connected to the first heat radiating portion 100 b and is also connected to the heat exchanger 107. A heat exchange medium flows through the first circulation channel 102, the second circulation channel 103, and the heat radiation channel 106, respectively. The first circulation channel 102 and the air conditioning heat exchanger 104 are connected via the channels 108a and 108b and the branch valve 105a, and the second circulation channel 103 and the air conditioning heat exchanger 104 are connected to each other. Are connected via the flow paths 109a and 109b and the branch valve 105b. In addition, the arrow in FIG. 1 has shown the distribution direction of the heat exchange medium.

  In this air conditioner, the heat of the heat exchange medium in the first circulation channel 102 is cooled by receiving heat absorption by the first heat absorption unit 100a. For this reason, the branch valve 105a allows the first circulation channel 102 and the channels 108a and 108b to communicate with each other, whereby the air conditioning heat exchanger 104 performs air conditioning in the first connection state (hereinafter referred to as first air conditioning). Done. For this reason, the room is cooled by the first air conditioning. The heat of the heat exchange medium absorbed by the first heat absorption part 100a is radiated from the first heat radiation part 100b to the heat exchange medium in the heat radiation channel 106, and is released to the outside of the air conditioner by the heat exchanger 107. The Rukoto.

  On the other hand, when performing cooling stronger than the first air conditioning, the heat of the heat exchange medium in the second circulation channel 103 is absorbed by the second heat absorbing unit 101a. At this time, the second heat dissipating part 101b dissipates heat to the cooled heat exchange medium in the first circulation channel 102, so the second heat absorbing part 101a absorbs more heat from the heat exchange medium. It becomes possible. For this reason, the heat exchange medium in the second circulation channel 103 is cooled more than the heat exchange medium in the first circulation channel 102. Then, the branch valve 105a connects the second circulation channel 102 and the channels 108a and 108b, whereby the air conditioning heat exchanger 104 performs air conditioning in the second connection state (hereinafter referred to as second air conditioning). Is called. Thus, the room is more strongly cooled by the second air conditioning. At this time, the branch valve 105a allows the first circulation channel 102 and the channels 108a and 108b to communicate with each other, thereby performing mixed air conditioning by the first air conditioning and the second air conditioning. It is also possible to cool the air.

  Moreover, the air conditioner of this invention WHEREIN: A 1st heat pump can have a 1st heat absorption part and a 1st thermal radiation part.

In addition, the first circulation channel is thermally connected to the first heat dissipating part of the first heat pump, the second heat absorbing part of the second heat pump is thermally connected to the first circulation channel, and the second heat pump The second circulation channel may be thermally connected to the second heat radiating unit. And the switching means can switch between the 1st connection state which connects the 1st circulation channel and the heat exchanger for air conditioning, and the 2nd connection state which connects the 2nd circulation channel and the heat exchanger for air conditioning. (Claim 3). In this case, the air conditioner can be configured as shown in FIG. 2, for example. Hereinafter, the effect of this air conditioner will be described based on the air conditioner shown in FIG.

Further, the second circulation channel 103 is thermally connected to the second heat radiating portion 101b. The heat radiation channel 106 is thermally connected to the first heat absorbing unit 100a and is connected to the heat exchanger 107. Other configurations are the same as those of the air conditioner shown in FIG. In FIG. 2 as well, the arrows indicate the flow direction of the heat exchange medium.

  In this air conditioner, the first heat absorption unit 100 a absorbs the heat of the heat exchange medium in the heat radiation channel 106, and the first heat radiation unit 100 b radiates heat to the heat exchange medium in the first circulation channel 102. For this reason, the heat exchange medium in the first circulation channel 102 is heated. For this reason, the branch valve 105a makes the 1st circulation flow path 102 and the flow paths 108a and 108b connect, 1st air conditioning is performed in the heat exchanger 104 for air conditioning, and the room | chamber interior is heated by 1st air conditioning.

  On the other hand, when heating stronger than the first air conditioning is performed, the second heat radiating unit 101 b radiates heat to the heat exchange medium in the second circulation channel 103. At this time, since the second heat absorbing unit 101a absorbs heat from the heated heat exchange medium in the first circulation channel 102, the second heat dissipating unit 101b can dissipate more heat. For this reason, the heat exchange medium in the second circulation channel 103 is heated more than the heat exchange medium in the first circulation channel 102. And the 2nd air conditioning is performed in the heat exchanger 104 for an air conditioning because the branch valve 105b connects the 2nd circulation flow path 103 and the flow paths 109a and 109b. Thus, the room is more strongly heated by the second air conditioning. In addition, by the same method as the air conditioner shown in FIG. 1 described above, this air conditioner can also perform mixed air conditioning using the first air conditioner and the second air conditioner, and thereby can heat the room.

  The air conditioner of the present invention may include a plurality of air conditioner heat exchangers. Any one of the air conditioning heat exchangers may be connected to the first circulation flow path, and the other air conditioning heat exchanger may be connected to other circulation flow paths except the first circulation flow path. ). In this case, said 1st air conditioning and 2nd air conditioning will be performed by the heat exchanger for a separate air conditioning, respectively.

  Moreover, in the air conditioner of this invention, the heat exchanger for an air conditioning may be one. And the heat exchanger for an air conditioning can be connected to the 1st circulation channel and other circulation channels except the 1st circulation channel (Claim 5). In this case, as shown in FIGS. 1 and 2 above, the configuration of the air conditioner can be simplified. For this reason, in this air conditioner, the interior of the room can be suitably air-conditioned, and the manufacturing cost can be reduced.

  The first heat pump is configured to heat the chemical substance and vaporize the reactant, to connect to the regeneration chamber by the first connection channel, to condense the vaporized reactant, and to the second connection channel. Connected to the condensing chamber, the evaporation chamber for vaporizing the condensed reactant, and the evaporation chamber by the third connection flow path, and the regeneration chamber by the fourth connection flow path and the fifth connection flow path, It may be a chemical heat pump having an absorption chamber for absorbing the vaporized reactant into the chemical substance. Further, the first circulation channel can be connected to the evaporation chamber. Furthermore, the second heat pump may be a thermoelectric conversion module having a heat absorption surface and a heat dissipation surface. The second circulation channel is preferably thermally connected to the endothermic surface (Claim 6).

  In this case, the heat radiating part of the thermoelectric conversion module can radiate heat with respect to the heat exchange medium in the first circulation channel cooled in the evaporation chamber. For this reason, the heat absorption part of the thermoelectric conversion module can absorb more heat from the heat exchange medium in the second circulation channel. For this reason, compared with the heat exchange medium in the first circulation channel connected to the evaporation chamber, the heat exchange medium in the second circulation channel thermally connected to the heat absorption surface of the thermoelectric conversion module is further cooled. The Rukoto. For this reason, in this air conditioner, in addition to cooling the room based on the first air conditioning, it is possible to cool the room more strongly based on the second air conditioning. It is also possible to perform indoor air conditioning by mixed air conditioning using the first air conditioning and the second air conditioning.

The pipe 59 is connected to the motor 7 and the branch valve V5. The pipe 60 is connected to the branch valve V5 at one end side and is connected to the pipe 61 at the other end side. The pipe 61 is connected to the pipe 60 and connects the pipe 60 and the other surface side heat exchanger 21. The pipe 62 is connected to the other surface side heat exchanger 21 and the second air conditioning heat exchanger 23. The pipe 63 is connected to the branch valve V5 at one end side and is connected to the pipe 57 at the other end side. The pipe 62 is provided with a seventh pump P7. The branch valve V5 and the seventh pump P7 are electrically connected to a control device (not shown). The seventh pump P7 may be provided in the pipe 57.

  The second air conditioning flow path 16 is connected to the electrical system heat radiation flow path 12 via pipes 64 and 65. Specifically, the pipe 64 is connected to the branch valve V3 at one end side and is connected to the pipe 61 at the other end side. The pipe 65 is connected to the branch valve V5 at one end side and is connected to the pipe 35 at the other end side.

  The thermoelectric conversion module 17 includes a pair of substrates constituting the one surface 17a side and the other surface 17b side, and a plurality of thermoelectric conversion elements sandwiched between the substrates (each substrate and each thermoelectric conversion element are not shown). It has. The thermoelectric conversion module 17 is electrically connected to a control device (not shown), and switches the heat absorption surface and the heat dissipation surface between the one surface 17a side and the other surface 17b side by switching the direction of the applied current. Is possible. The thermoelectric conversion module 17 corresponds to a second heat pump, the heat absorption surface of the thermoelectric conversion module 17 corresponds to a second heat absorption portion, and the heat dissipation surface of the thermoelectric conversion module 17 corresponds to a second heat dissipation portion. The thermoelectric conversion module 17 is located between the one surface side heat exchanger 19 provided on the one surface 17a side of the thermoelectric conversion module 17 and the other surface side heat exchanger 21 provided on the other surface 17b side. Yes. Thereby, the thermoelectric conversion module 17 as a 2nd heat absorption part and a 2nd thermal radiation part is in the state thermally connected to the flow path 14 for 1st air conditioning and the flow path 16 for 2nd air conditioning. In addition to each substrate and thermoelectric conversion element provided in the thermoelectric conversion module 17, known ones are adopted for the one side heat exchanger 19 and the other side heat exchanger 21, respectively, and the configuration of the thermoelectric conversion module 17 and the like. The detailed description about is omitted. In addition, a so-called skeleton type thermoelectric conversion module that does not have each substrate may be employed.

  The first air conditioning channel 14, the second air conditioning channel 16, the sixth and seventh pumps P6 and P7, the branch valves V4 and V5, and the control device correspond to a switching unit.

  In the air conditioner configured as described above, when the vehicle is driven by driving the engine 3 (when the engine is running) and when the vehicle is driven by the motor 7 (when EV is running), the air conditioner is in the state shown in FIGS. Cool the passenger compartment. In addition, the broken-line arrow in FIGS. 4-8 has shown the moving direction of heat. Other arrows will be appropriately described below. The same applies to FIGS. 9 and 11 to be described later.

(Cooling when the engine is running)
In this case, the control device operates the branch valves V1 to V4, respectively. Accordingly, as shown in FIG. 4, in the engine heat dissipation channel 10, the pipe 25 and the pipe 28 are communicated, and the pipes 25, 28 and the pipe 26 are not communicated. Moreover, in the electrical system heat radiation flow path 12, the piping 29 and the piping 34 are connected, and the piping 29, 34 and the piping 30 are not connected. Further, the pipe 34 and the pipe 35 are communicated, and the pipes 34 and 35 and the pipe 64 are not communicated. Since the branch valve V5 is not connected to any pipe, the pipe 35 and the pipe 65 are not in communication. In the first air conditioning channel 14, the pipe 54 and the pipe 55 are communicated, and the pipes 54 and 55 and the pipe 56 are not communicated. In this state, the control device operates the first to sixth pumps P1 to P6. For these reasons, in the engine heat dissipation channel 10, the electrical system heat dissipation channel 12, and the first air conditioning channel 14, the engine coolant, the electrical system coolant, and the air conditioning coolant are respectively shown in the directions of the solid arrows in FIG. Each circulates. Further, the control device operates the electric fans 5a, 11a, and 15a, respectively.

  As a result, in this air conditioner, the engine coolant heated by the driving engine 3 flows through the pipe 28 and heats the LiBr aqueous solution C1 in the regeneration chamber 41. For this reason, in the LiBr aqueous solution C1, the water C2 is separated from the LiBr aqueous solution C1 in the state of water vapor (heat dehydration). The water C2 that has become the water vapor passes from the regeneration chamber 41 to the condensing chamber 43 via the first connection flow path 45 (see the dashed line arrow in the figure). In the condensing chamber 43, the water (water vapor) C <b> 2 is cooled and condensed by the electrical system coolant in the pipe 33 and stored in the condensing chamber 43 in a liquid state. As described above, since the motor 7 and the PCU 9 generate a small amount of heat while the engine 3 is being driven, the electrical system coolant in the pipe 33 can sufficiently cool the water C2. The water C2 stored in the condensing chamber 43 reaches from the condensing chamber 43 to the evaporating chamber 44 via the second connection flow path 46 by the fifth pump P5 (see the one-dot chain line arrow in the figure). .) On the other hand, the LiBr aqueous solution C1 from which the water C2 has been separated and dehydrated / concentrated reaches the absorption chamber 42 via the fourth connection channel 48 by the third pump P3 (the two-dot chain line in the figure). See arrow.)

  As described above, since the inside of the evaporation chamber 44 is in a state of being depressurized more than the surroundings, the water C2 reaching the evaporation chamber 44 is vaporized in the evaporation chamber 44. At this time, cold energy is stored in the evaporation chamber 44 by heat of vaporization. The vaporized water (water vapor) C2 reaches the absorption chamber 42 via the third connection flow path 47 (see the one-dot chain line arrow in the figure). For this reason, in the absorption chamber 42, the vaporized water C2 is absorbed by the LiBr aqueous solution C1 that has been dehydrated and concentrated. At this time, an exothermic reaction occurs, but the absorption chamber 42 is prevented from being heated to a high temperature by the electrical system coolant in the pipe 33. For this reason, the water C2 is suitably absorbed, and the vaporization of the water C2 in the evaporation chamber 44 is promoted. On the other hand, the LiBr aqueous solution C1 that has absorbed the water C2 reaches the regeneration chamber 41 via the fifth connection channel 49 by the fourth pump P4 (see the white arrow in the figure).

  The cooling liquid stored in the evaporation chamber 44 by the heat of vaporization cools the air-conditioning coolant in the pipe 53. The cooled air-conditioning coolant reaches the first air-conditioning heat exchanger 15 via the pipes 53 to 55, and cools the air around the first air-conditioning heat exchanger 15. The cooled air is supplied to the vehicle interior by the electric fan 15a, so that the air conditioner cools the vehicle interior (first air conditioning).

  On the other hand, the dehydrated and concentrated LiBr aqueous solution C1 flowing through the fourth connection flow channel 48 and the LiBr aqueous solution C1 flowing through the fifth connection flow channel 49 exchange heat in the heat exchanger 51. At this time, since the dehydrated and concentrated LiBr aqueous solution C1 flowing through the fourth connection channel 48 is at a high temperature due to the heat dehydration in the regeneration chamber 41, LiBr flowing through the fifth connection channel 49 is used. The aqueous solution C1 is heated in the heat exchanger 51 and reaches the regeneration chamber 41 in a higher temperature state. On the other hand, the dehydrated and concentrated LiBr aqueous solution C <b> 1 flowing through the fourth connection channel 48 is cooled in the heat exchanger 51 and reaches the absorption chamber 42. Therefore, in the absorption chamber 42, the water C2 is easily absorbed by the LiBr aqueous solution C1 that has been dehydrated and concentrated, and the LiBr aqueous solution C1 is likely to be heated and dehydrated in the regeneration chamber 41. For this reason, in this air conditioner, in the chemical heat pump 13, separation and absorption of the LiBr aqueous solution C <b> 1 and the water C <b> 2 are suitably performed, and cold heat is suitably stored in the evaporation chamber 44. For this reason, in this air conditioner, the cooling capacity is high. The engine coolant in the pipe 26 that has finished heating the regeneration chamber 41 reaches the engine radiator 5 from the pipe 25 and is cooled by exchanging heat with the air around the engine radiator 5.

  The electrical system coolant in the pipe 34 that has passed through the absorption chamber 42 and the condensation chamber 43 cools the motor 7 and the PCU 9 and then reaches the electrical system radiator 11 through the pipe 33. And in the electrical equipment radiator 11, it heat-exchanges with the air outside a vehicle compartment, and is cooled.

  Further, in this air conditioner, when the cooling capacity is insufficient in the first air conditioning based on the cold in the evaporation chamber 44, the control device operates the branch valves V4 and V5 and the seventh pump P7, respectively. Thereby, as shown in FIG. 5, in the first air conditioning flow path 14, the pipe 54 and the pipe 56 are communicated, and the pipes 54 and 56 and the pipe 55 are not communicated. Further, in the second air conditioning channel 16, the pipe 60 and the pipe 63 are communicated, and the pipe 60 and the pipes 59 and 65 are not communicated. For these reasons, in the first air conditioning flow path 14 and the second air conditioning flow path 16, the air conditioning coolant or the electrical system coolant circulates in the direction of the solid arrow in FIG. In the engine heat dissipation channel 10 and the electrical system heat dissipation channel 12, the engine coolant or the electrical system coolant circulates as in the case shown in FIG. In this state, the control device operates by setting the one surface 17a side of the thermoelectric conversion module 17 as a heat dissipation surface and the other surface 17b side as a heat absorption surface. Further, the control device operates the electric fan 23a and stops the operation of the electric fan 15a.

  For these reasons, in the second air conditioning channel 16, the electrical system coolant in the other surface side heat exchanger 21 receives the heat absorbed by the thermoelectric conversion module 17 and is cooled. The heat of the electrical system coolant absorbed by the thermoelectric conversion module 17 is dissipated to the air conditioning coolant in the one-side heat exchanger 19. At this time, since the cooling liquid for air conditioning is cooled by the cold heat in the evaporation chamber 44, the thermoelectric conversion module 17 can dissipate more heat to the cooling liquid for air conditioning. For this reason, in the other surface side heat exchanger 21, the electrical system coolant is sufficiently cooled. For this reason, the electrical system coolant in the second air conditioning channel 16 is cooled more than the air conditioning coolant in the first air conditioning channel 14.

  Then, the cooled electrical system coolant reaches the second air conditioning heat exchanger 23 through the pipe 62 and cools the air around the second air conditioning heat exchanger 23. The cooled air is supplied into the vehicle interior by the electric fan 23a, so that the air-conditioning apparatus performs stronger cooling of the vehicle interior (second air conditioning).

(Cooling during EV travel)
Since the engine 3 is not driven during EV traveling, the regeneration chamber is heated by the engine coolant heated by heat exchange in the engine radiator 5. For this reason, in this air conditioner, it is possible to perform the second air conditioning based on the heat absorption by the thermoelectric conversion module 17 in addition to the first air conditioning based on the heat absorption by the chemical heat pump 13 as in the cooling at the time of driving the engine.

(Heating during engine running and EV running)
In this case, the control device operates the branch valves V4 and V5 based on the state shown in FIG. Thereby, as shown in FIG. 6, in the electrical system heat radiation flow path 12, the pipe 34 and the pipe 64 are communicated, and the pipe 35 and the pipe 65 are communicated, and the pipe 34 and the pipe 35 are directly connected. Not communicated. In the second air conditioning channel 16, the pipe 63 and the pipe 65 are communicated, and the pipe 63 and the pipes 59 and 60 are not communicated. That is, a part of the electrical system heat radiation passage 12 and a part of the second air conditioning passage 16 are communicated with each other via the pipes 64 and 65.

  As a result, the electrical system coolant in the pipe 34 heated through the absorption chamber 42 and the condensation chamber 43 flows in the order of the pipes 64, 61, 62 and reaches the second air conditioning heat exchanger 23. The air around the second air conditioning heat exchanger 23 is heated by the heated electrical system coolant. The heated air is supplied to the vehicle interior by the electric fan 23a, so that the air conditioner heats the vehicle interior. At this time, the control device operates with the one surface 17a side of the thermoelectric conversion module 17 as the heat absorbing surface and the other surface 17b side as the heat radiating surface. It is also possible to further heat the electrical system coolant in 21. Thereby, stronger heating of the passenger compartment can also be performed.

  After the heat exchange in the second air conditioning heat exchanger 23 is finished, the cooled electrical system coolant reaches the pipe 35 via the pipes 63 and 65. After the motor 7 and the PCU 9 are cooled, the electrical system radiator 11 is cooled by exchanging heat with the air outside the passenger compartment. The branch valve V5 may be switched so that the electrical system coolant reaches the pipe 35 via the pipes 58 and 59. In this case, the motor 7 and the PCU 9 are cooled by the electrical system coolant before reaching the pipe 35.

  Further, in a state where the motor 7 and the PCU 9 are sufficiently generating heat, such as during EV travel, heating can be performed by operating the branch valves V4 and V5 as follows. In this case, as shown in FIG. 7, in the electrical system heat radiation channel 12, the pipe 34 and the pipe 35 are communicated, the pipe 34 and the pipe 64 are not communicated, and the pipe 35 and the pipe 65 are not communicated. Communicated. That is, the electrical system heat radiation flow path 12 and the second air conditioning flow path 16 are not communicated. Further, in the second air conditioning channel 16, the pipe 59 and the pipe 60 are communicated, and the pipes 59 and 60 and the pipe 63 are not communicated.

  In this state, in the second air conditioning flow path 16, the electrical system coolant heated by the motor 7 and the PCU 9 reaches the second air conditioning heat exchanger 23 through the pipes 59 to 62. And like said heating, the heated air will be supplied by the electric fan 23a in a vehicle interior, and a vehicle interior will be heated. In this case as well, it is possible to further heat the electrical system coolant in the other surface side heat exchanger 21 by heat radiation by the thermoelectric conversion module 17.

  During each of these heating operations, the air-conditioning coolant cooled by the cold heat in the evaporation chamber 44 flows through the first air-conditioning flow path 14 (see FIGS. 6 and 7). For this reason, at the time of each of these heating, if a control apparatus operates the branch valve V4, the piping 54 and the piping 55 are connected, and the cooling fluid for an air conditioning is distribute | circulated in the heat exchanger 15 for a 1st air conditioning. It is also possible. As a result, the air around the first air conditioning heat exchanger 15 is cooled and dehumidified. For this reason, it is also possible to supply the dehumidified air to the vehicle interior by operating the electric fan 15a during the heating, and to dehumidify simultaneously with the heating of the vehicle interior. That is, mixed air conditioning by the first air conditioning and the second air conditioning can be performed. At this time, the cooled and dehumidified air is reheated by the air heated by heat exchange in the second air conditioning heat exchanger 23. For this reason, it is difficult for the dehumidification to prevent the vehicle interior from being heated.

  Furthermore, when it is not necessary to operate the chemical heat pump 13, in this air conditioner, the control device stops the operations of the third to sixth pumps P3 to P6 and switches the branch valves V1, V2, and V5. Further, the branch valves V3 and V4 are not connected to any piping. As a result, as shown in FIG. 8, in the engine heat dissipation channel 10, the pipe 25 and the pipe 26 are communicated, and the pipes 25 and 26 and the pipe 28 are not communicated. Moreover, in the electrical system heat radiation flow path 12, the piping 29 and the piping 30 are connected, and the piping 29, 30 and the piping 34 are not connected. In the second air conditioning channel 16, the pipe 59 and the pipe 60 are communicated, and the pipes 59 and 60 and the pipe 63 are not communicated.

  For this reason, in the second air conditioning channel 16, the electrical system coolant is heated by the motor 7 and the PCU 9. Then, in the second air conditioning heat exchanger 23, heat is exchanged by the heated electrical system coolant, and the vehicle interior is heated in the same manner as in the above heating. The heat of the motor 7 and the PCU 9 that has not been used for heating the vehicle interior is heat-exchanged with the air outside the vehicle interior by the electrical system coolant and the electrical system radiator 11 that circulates in the electrical system heat radiation passage 12.

  In this state, in the engine heat dissipation channel 10, the engine coolant does not pass through the pipe 28, and the flow resistance of the engine coolant in the engine heat dissipation channel 10 is reduced. Similarly, in the electrical system heat radiation channel 12, the electrical system coolant does not pass through the pipe 34, and the flow resistance of the electrical system coolant in the electrical system heat radiation channel 12 is reduced. Furthermore, the regeneration chamber 41 is prevented from being unnecessarily heated by the engine coolant in the pipe 28, and the absorption chamber 42 and the condensation chamber 43 are unnecessarily cooled by the electrical system coolant in the pipe 34. This is also prevented. For these reasons, this air conditioner can effectively prevent deterioration and alteration of the LiBr aqueous solution C1 and water C2.

  Thus, in this air conditioner, the thermoelectric conversion module 17 can further absorb heat based on the heat absorption performed by the evaporation chamber 44 in the chemical heat pump 13. For this reason, a temperature difference will be generated between the air conditioning coolant flowing through the first air conditioning flow path 14 and the electrical system coolant flowing through the second air conditioning flow path 16. That is, in this air conditioner, during cooling, the electrical system coolant in the second air conditioning channel 16 is at a lower temperature than the air conditioning coolant in the first air conditioning channel 14.

  More specifically, in this air conditioner, the chemical heat pump 13 absorbs heat based on heat generated by the engine 3 at the time of driving and heat exchange by the engine radiator 5 and is used for the first air conditioning. For this reason, cold heat is obtained. The thermoelectric conversion module 17 cools the electrical system coolant flowing through the second air conditioning flow path 16 based on the cold heat obtained by the chemical heat pump 13 to obtain cold heat for use in the second air conditioning. ing.

  In other words, since the cold heat stored in the evaporation chamber 44 of the chemical heat pump 13 depends on the heat generated by the heat generation of the engine 3 and the heat exchange by the engine radiator 5, the cold heat used for the first air conditioning includes Variation in temperature is likely to occur. In contrast, the thermoelectric conversion module 17 absorbs heat from the electrical system coolant in the second air conditioning channel 16 and can radiate heat to the cooled air conditioning coolant in the first air conditioning channel 14. For this reason, the thermoelectric conversion module 17 can absorb a lot of heat stably from the electrical system coolant of the second air conditioning flow path 16. For this reason, the electrical system coolant flowing through the second air conditioning flow path 16 is set to a lower temperature than the air conditioning coolant flowing through the first air conditioning flow path 14. For this reason, during cooling, the second air conditioner can cool the room at a lower temperature than the first air conditioner. Further, in the mixed air conditioning, the air cooled and dehumidified in the first air conditioning heat exchanger 15 is reheated by the air heated by the heat exchange in the second air conditioning heat exchanger 23, and preferably It is possible to dehumidify indoors.

  In this air conditioner, the control unit controls the first air conditioning flow path 14, the second air conditioning flow path 16, the sixth and seventh pumps P6 and P7, and the branch valves V4 and V5. It is possible to switch between the second air conditioning and the mixed air conditioning. For this reason, in this air conditioner, the first air conditioner, the second air conditioner, and the mixed air conditioner can be used properly according to the purpose, and it is easy to adjust the temperature during the air conditioning.

  Therefore, according to this air conditioner, the room can be suitably air-conditioned.

(Example 2)
As shown in FIG. 9, in the air conditioner of Example 2, the first air conditioning flow path 14 is configured by pipes 71 to 77. Further, a branch valve V <b> 6 is provided between the pipe 72 and the pipe 73.

  The pipe 71 is connected to the first air conditioning heat exchanger 15 and the pipe 72. The pipe 72 is connected to the branch valve V6 at one end side and is connected to the pipe 71 at the other end side. The pipe 71 extends into the evaporation chamber 44 and is formed to meander in the evaporation chamber 44. The piping 73 is connected to the one surface side heat exchanger 19 and the branch valve V6. The piping 74 is connected to the one surface side heat exchanger 19 and the branch valve V4. The pipe 75 is connected to the branch valve V4 and the first air conditioning heat exchanger 15. The pipe 76 is connected to the branch valve V4 on one end side and is connected to the pipe 71 on the other end side. The pipe 77 is connected to the branch valve V6 at one end side and is connected to the pipe 71 at the other end side. The pipe 71 is provided with a sixth pump P6. The branch valve V6 is electrically connected to a control device (not shown). This branch valve V6 also corresponds to the switching means. Note that the sixth pump P6 may be provided on the pipe 73 side or the pipe 74 side. Other configurations are the same as those of the air conditioner according to the first embodiment. The same components are denoted by the same reference numerals, and detailed description thereof is omitted.

  In this air conditioner, the control device operates the branch valve V6 to connect the pipe 72 and the pipe 73 and to disconnect the pipes 72 and 73 and the pipe 77 from each other. Further, the control device appropriately switches the case where the branch valve V4 is operated to connect the pipe 74 and the pipe 75 and the case where the pipe 74 and the pipe 76 are connected. Accordingly, the air-conditioning coolant flows in the first air-conditioning flow path 14 and the first air-conditioning can be performed. Moreover, it becomes possible to perform the 2nd air conditioning based on the heat absorption of the thermoelectric conversion module 17 because the control device operates the thermoelectric conversion module 17. For these reasons, also in this air conditioner, it is possible to cool, heat, and dehumidify the passenger compartment in the same manner as the air conditioner of the first embodiment when the engine is running and the EV is running.

  In this air conditioner, for example, the control device operates the branch valves V4 to V6 during heating of the passenger compartment with the chemical heat pump 13 stopped. Thereby, in the 1st air-conditioning flow path 14, the piping 74 and the piping 75 are connected, and the piping 74 and 75 and the piping 76 are made non-communication. Further, the pipe 77 and the pipe 73 are communicated, and the pipes 73 and 77 and the pipe 72 are not communicated. On the other hand, in the second air conditioning channel 16, the pipe 59 and the pipe 60 are communicated, and the pipes 59 and 60 and the pipe 63 are not communicated. In this state, the control device operates by setting the one surface 17a side of the thermoelectric conversion module 17 as a heat dissipation surface and the other surface 17b side as a heat absorption surface. Then, the control device operates the electric fan 15a and stops the electric fan 23a.

  Thereby, in the second air conditioning channel 16, the electrical system coolant heated by the motor 7 and the PCU 9 receives heat absorbed by the thermoelectric conversion module 17 in the other surface side heat exchanger 21. In the first air conditioning channel 14, the air conditioning coolant is heated by receiving heat radiation from the thermoelectric conversion module 17 in the one-side heat exchanger 19. The heated air conditioning cooling reaches the inside of the first air conditioning heat exchanger 15 through the pipes 74 and 75, and heats the air around the first air conditioning heat exchanger 15. Thus, in this air conditioner, the vehicle interior can also be heated by the electric fan 15a supplying the heated air to the vehicle interior. In this case, since the thermoelectric conversion module 17 absorbs heat of the electrical system coolant heated by the motor 7 and the PCU 9 and dissipates heat to the air conditioning coolant, the air conditioning coolant is further heated. . For this reason, it is possible to heat the passenger compartment more strongly.

  At this time, the electrical system coolant in the second air conditioning channel 16 is cooled by receiving heat absorbed by the thermoelectric conversion module 17. For this reason, the air around the second air conditioning heat exchanger 23 is cooled and dehumidified by heat exchange with the cooled electrical system coolant. For this reason, it is also possible to dehumidify the passenger compartment by operating the electric fan 23a by the control device. It is also possible to reheat the dehumidified air with the air around the first air conditioning heat exchanger 15.

  In these cases, since the pipe 72 and the pipe 73 are not in communication, the air-conditioning coolant in the first air-conditioning heat exchanger 15 reaches the pipe 77 from the pipe 71. For this reason, the evaporating chamber 44, the water C2 in the evaporating chamber 44, and the like are not warmed by the air conditioning coolant flowing in the pipe 72. For this reason, in this air conditioner, even if the air-conditioning coolant is heated and heated as described above, the deterioration and alteration of the water C2 in the chemical heat pump 13 can be effectively prevented. Other functions and effects are the same as those of the air conditioner of the first embodiment.

(Example 3)
As shown in FIG. 10, the air conditioner of Example 3 includes one air conditioner heat exchanger 18. The air conditioner heat exchanger 18 is provided in the passenger compartment. The air-conditioning heat exchanger 18 is connected to the first air-conditioning flow path 14 and the second air-conditioning flow path 16 so that the air-conditioning coolant or the electrical system coolant can flow through the interior. The air conditioner heat exchanger 18 can exchange heat between the air conditioning coolant or the electrical system coolant in the air conditioner heat exchanger 18 and the air around the air conditioner heat exchanger 18. Yes. The air conditioner heat exchanger 18 includes an electric fan 18a. The electric fan 18a is electrically connected to a control device (not shown).

  Further, in this air conditioner, the first air conditioning flow path 14 is constituted by the pipes 78 to 83, and the second air conditioning flow path 16 is constituted by the pipes 84 to 90. A branch valve V 7 is provided between the pipe 78 and the pipe 79, and a branch valve V 8 is provided between the pipe 81 and the pipe 82.

  The piping 78 is connected to the heat exchanger 18 for air conditioning and the branch valve V7. The pipe 79 is connected to the branch valve V <b> 7 and the one surface side heat exchanger 19. The pipe 79 extends into the evaporation chamber 44 and is formed to meander in the evaporation chamber 44. The pipe 80 is connected to the one surface side heat exchanger 19 and the branch valve V4. The pipe 81 is connected to the branch valve V4 on one end side and is connected to the branch valve V8 on the other end side. The pipe 82 is connected to the branch valve V8 on one end side and is connected to the air conditioner heat exchanger 18 on the other end side. The pipe 83 is connected to the branch valve V4 on one end side and to the pipe 79 on the other end side.

  The pipe 84 is connected to the PCU 9 and the motor 7. The pipe 85 is connected to the motor 7 and the branch valve V5. The pipe 86 is connected to the branch valve V5 at one end side and is connected to the pipe 87 at the other end side. The pipe 87 is connected to the pipe 86, and connects the pipe 86 and the other surface side heat exchanger 21. A pipe 64 is connected to the pipe 87. The pipe 88 is connected to the other surface side heat exchanger 21 and the branch valve V8. The pipe 89 is connected to the branch valve V7 on one end side and to the PCU 9 on the other end side. The pipe 90 is connected to the branch valve V5 at one end side and is connected to the pipe 89 at the other end side. The piping 88 is provided with a seventh pump P7. The seventh pump P7 may be provided in the pipes 87 and 89.

  The first air conditioning channel 14 and the second air conditioning channel 16 are connected via branch valves V7 and V8 and pipes 88 and 89, respectively. These branch valves V7 and V8 also correspond to the switching means. Other configurations are the same as those of the air conditioner according to the first embodiment. The same components are denoted by the same reference numerals, and detailed description thereof is omitted.

  In this air conditioner, the first air conditioning and the second air conditioning are performed as follows when the engine is traveling and the EV is traveling.

  When performing 1st air conditioning, a control device operates branch valve V4, V7, and V8, respectively. Accordingly, as shown in FIG. 11, in the first air conditioning flow path 14, the pipe 80 and the pipe 81 are communicated, and the pipes 80 and 81 and the pipe 83 are not communicated. Moreover, the piping 78 and the piping 79 are connected, and the piping 78 and 79 and the piping 89 are not connected. Further, the pipe 81 and the pipe 82 are communicated, and the pipes 81 and 82 and the pipe 88 are not communicated. As a result, the first air conditioning channel 14 and the second air conditioning channel 16 are not in communication.

  In this state, the control device operates the first to sixth pumps P1 to P6 and the branch valves V1 to V3 and V5. Further, the control device operates the electric fans 5a and 11a and the electric fan 18a. In the first to sixth pumps P1 to P6, the branch valves V1 to V3 and V5, and the operation of the electric fans 5a and 11a, the engine heat dissipation channel 10, the electrical system heat dissipation channel 12, and the second air conditioning channel 16 are used. The circulation of the engine coolant or the electrical system coolant is the same as that of the air conditioner according to the first embodiment shown in FIG.

Cool the air. The cooled air is supplied to the passenger compartment by the electric fan 18a, thereby cooling the first air conditioner.

  Moreover, when performing 2nd air conditioning, a control apparatus operates branch valve V4, V5, V7, V8 from the state at the time of 1st air conditioning, respectively. Accordingly, as shown in FIG. 12, in the first air conditioning flow path 14, the pipe 80 and the pipe 83 are communicated, and the pipes 80 and 83 and the pipe 81 are not communicated. Further, the pipe 78 and the pipe 89 are communicated, and the pipes 78 and 89 and the pipe 79 are not communicated. Further, the pipe 88 and the pipe 88 are communicated, and the pipes 82 and 88 and the pipe 81 are not communicated. In the second air conditioning channel 16, the pipe 86 and the pipe 90 are communicated, and the pipe 86 and the pipes 85 and 65 are not communicated. As a result, a part of the first air conditioning channel 14 and a part of the second air conditioning channel 16 are communicated.

Then, the air around the air conditioner heat exchanger 18 is cooled, and the electric fan 18a supplies the cooled air to the chamber, thereby cooling the second air conditioner. The electrical system coolant in the heat exchanger 18 for air conditioning reaches the PCU 9 from the pipe 78 through the pipe 89. The air-conditioning coolant that has received heat radiation from the thermoelectric conversion module 17 in the one-side heat exchanger 19 reaches the pipe 79 from the pipe 80 through the pipe 83. For this reason, the air-conditioning coolant and the electrical system coolant are not mixed.

  On the other hand, when heating the passenger compartment in this air conditioner, the control device operates the branch valves V3 and V5 from the state of the second air conditioner. For this reason, as shown in FIG. 13, the piping 34 and the piping 64 are connected, and the piping 34 and the piping 35 are not directly connected. Further, the pipe 90 and the pipe 64 are communicated via the branch valve V5, and the pipes 87 and 90 and the pipe 86 are not communicated.

And the air around the air conditioner heat exchanger 18 is heated, and the electric fan 18a supplies the cooled air to the room, so that the air conditioner can heat the vehicle interior. Even in this case, the control device operates by setting the one surface 17a side of the thermoelectric conversion module 17 as the heat absorbing surface and the other surface 17b side as the heat radiating surface. It is possible to further heat the electrical system coolant in the exchanger 21. Thereby, stronger heating of the passenger compartment can also be performed.

  Further, in a state where the motor 7 and the PCU 9 are sufficiently generating heat, such as during EV travel, the control device can operate the branch valves V3 and V5 to perform heating. In this case, as shown in FIG. 14, in the electrical system heat radiation channel 12, the pipe 34 and the pipe 35 are communicated, the pipe 34 and the pipe 64 are not communicated, and the pipe 35 and the pipe 65 are not communicated.

As in the case of the above heating, the heated air is supplied to the vehicle interior by the electric fan 18a and the vehicle interior is heated. Also in this case, it is possible to further heat the electrical system coolant in the other surface side heat exchanger 21 by heat radiation by the thermoelectric conversion module 17. As in the second air conditioning, the air conditioning coolant and the electrical system coolant are not mixed during the heating.

  When it is not necessary to operate the chemical heat pump 13, in this air conditioner, the control device stops the operations of the third to sixth pumps P3 to P6 and switches the branch valves V1, V2, and V5. Further, the branch valves V3 and V4 are not connected to any piping. The branch valves V7 and V8 are the same as in the above heating. That is, a part of the first air conditioning channel 14 and a part of the second air conditioning channel 16 are communicated. The circulation of the engine coolant or the electrical system coolant in the engine heat dissipation channel 10 and the electrical system heat dissipation channel 12 is the same as that of the air conditioner of Example 1 shown in FIG.

Thus, the vehicle interior is heated as in the case of the above heating.
