Become.

JP 2013-155906 A

  However, in the technique disclosed in Patent Document 1, when the exhaust heat on the vehicle side is used, it is necessary to connect the heat medium path on the building side and the heat medium path on the vehicle side with a connection pipe. It is possible to become. In addition, it is necessary to construct heat medium paths on the building side and the vehicle side, respectively, and it is necessary to provide connection ports for connecting connection pipes to these heat medium paths.

  The present invention has been made in view of the above circumstances, and a main object of the present invention is to provide a building heating system capable of improving heating efficiency with a relatively simple configuration without trouble.

  In order to solve the above problems, a building heating system according to a first aspect of the present invention is applied to a garage-equipped building having a garage space in which a vehicle can be parked in addition to a living space, and takes in air from the building. A heating device is provided that generates warm air by heating and supplies the warm air to the living space to be heated, and serves as a take-in route for taking in air into the heating device. It has one take-in route.

  By the way, when heat is discharged from the vehicle parked in the garage space, the air in the garage space is warmed by the discharged heat. Therefore, in the present invention, paying attention to this point, the first intake passage for taking in air in the garage space is provided as the intake passage for taking in air in the building into the heating device. In this case, the air in the garage space warmed by the exhaust heat of the vehicle can be taken into the heating device, so that the heating efficiency can be improved. Further, in this case, when taking in the exhaust heat of the vehicle to the building side, it is not necessary to connect the vehicle side and the building side by a connecting pipe, and it is not necessary to construct a heat transfer route between the vehicle side and the building side. There is no need to configure. Accordingly, it is possible to improve the heating efficiency without trouble with a relatively simple configuration.

  The building heating system according to a second aspect of the present invention includes, in the first aspect of the invention, a second intake path for taking in air in the living space as the intake path, and taking in air into the heating device It is characterized by comprising switching means capable of switching the mode to at least a first take-in mode for taking in air through the first take-in route and a second take-in mode for taking in air only through the second take-in route. To do.

  According to the present invention, the mode of taking air into the heating device is at least the mode of taking in air through the first take-in path (first mode of taking in), that is, the mode of taking in air from at least the garage space, It is possible to switch to an aspect in which air is taken in only through the intake path (second intake aspect), that is, an aspect in which air is taken in only from the living space. Therefore, for example, when the garage space is warmed by the exhaust heat of the vehicle, the first intake mode is switched to take in warm air from the garage space into the heating device, and the vehicle is not parked in the garage space. If the garage space is cold, the air can be taken in only from the living space by switching to the second intake mode. In this case, whether to take in air in the garage space can be switched depending on whether the garage space is heated by the exhaust heat of the vehicle. This can be said to be a practically preferable configuration.

  A building heating system according to a third aspect of the present invention is the building system according to the second aspect, wherein the garage space is in a predetermined warmed state heated by exhaust heat of the vehicle, and the garage space When it is determined that the warm-up state is present, the air intake mode into the heating device is the first capture mode, and when it is determined that the garage space is not in the warm-up state, the second mode is used. Switching control means for controlling the switching of the switching means so as to obtain a capture mode.

  According to the present invention, when the garage space is warmed by the exhaust heat of the vehicle (predetermined warm-up state), the air intake mode to the heating device is the first intake mode. In this case, since warm air in the garage space is taken into the heating device, the heating efficiency can be improved. On the other hand, when the garage space is not in the warm air state, the air intake mode into the heating device is the second intake mode. In this case, since air is taken into the heating device only from the living space, it is possible to prevent cold air from being taken into the garage space and causing a decrease in heating efficiency.

  A building heating system according to a fourth aspect of the present invention is the third aspect of the present invention, in the case where the warehousing determination means for determining that the vehicle has entered the garage space and the warehousing determination means determine the warehousing of the vehicle. Measuring means for measuring an elapsed time from the warehousing, and the determining means determines whether the garage space is in the warm-up state based on the elapsed time measured by the measuring means. It is characterized by.

  By the way, it is considered that immediately after the vehicle enters the garage space, the garage space is warmed by the exhaust heat of the stored vehicle. Therefore, in the present invention, focusing on this point, when a vehicle enters the garage space, the elapsed time from the warehousing is measured, and whether or not the garage space is in a warm air state based on the elapsed time. Judgment is made. In this case, it can be suitably determined whether or not the garage space is in a warm air state.

  A building heating system according to a fifth aspect of the present invention includes the vehicle determination means according to the third or fourth aspect, further comprising vehicle determination means for determining whether or not the vehicle stored in the garage space is an exhaust gas vehicle that exhausts exhaust gas. When the vehicle determination means determines that the vehicle is the exhaust gas vehicle, the switching control means sets the air intake mode to the heating device regardless of the determination result of the determination means. It is characterized by switching to the capture mode.

  According to the present invention, when the exhaust gas vehicle enters the garage space, the air intake mode to the heating device is switched to the second intake mode regardless of whether the garage space is in a warm air state. . That is, in this case, since the intake of air in the garage space to the heating device is prohibited, it is possible to prevent the exhaust gas of the vehicle from being taken into the heating device.

  In the building heating system according to a sixth aspect of the present invention, in any one of the first to fifth aspects of the present invention, the warm air supplied to the living space to be heated is transferred from the living space to the garage space. And an opening for allowing the warm air to flow from the return air path into the garage space opens toward the vehicle parked in the garage space.

  According to the present invention, when warm air is supplied to the living space to be heated by the heating device, the warm air flows from the living space to the garage space through the return air path. Therefore, when the heating device takes in the air in the garage space and generates warm air, the warm air (air) circulates between the living space and the garage space. In such a configuration, in the present invention, since the opening for allowing warm air (air) to flow from the return air path into the garage space opens toward the vehicle parked in the garage space, the warm air flowing from the opening to the garage space. Is taken around the first take-in passage and then into the heating device after passing through the periphery of the vehicle. In this case, since the exhaust heat of the vehicle can be suitably taken into the heating device, the heating efficiency can be further improved.

  The building heating system according to a seventh aspect of the present invention is the heating system according to any one of the first to sixth aspects, wherein the floor space of the living space to be heated is higher than the floor surface of the garage space. Under the living space, an underfloor space is provided side by side with the garage space, and a floor connecting the living space and the underfloor space is provided with a first communication port that communicates the two spaces. The wall part which partitions the said underfloor space and the said garage space is provided with the 2nd communicating port which connects both these space, It is characterized by the above-mentioned.

  According to the present invention, when warm air is supplied to the living space to be heated by the heating device, the warm air flows from the living space to the under floor space through the first communication port, and then from the under floor space to the garage through the second communication port. Flow into the space. Therefore, when the heating device takes in air in the garage space and generates warm air, the warm air (air) circulates between the living space, the underfloor space, and the garage space. Here, since the 2nd communication port is provided in the wall part which partitions the underfloor space and the garage space, it can be said that the 2nd communication port is located in the height range of the vehicle parked in the garage space. Therefore, the warm air flowing into the garage space from the second communication port is taken into the first intake passage and then to the heating device after passing through the periphery of the vehicle. Therefore, also in this case, it is possible to obtain the same effect as the sixth invention.

  In a building heating system according to an eighth aspect of the present invention, in any one of the first to seventh aspects, the vehicle parked in the garage space is an electric vehicle that travels using electric power.

  According to the present invention, the vehicle parked in the garage space is an electric vehicle that does not discharge exhaust gas. For this reason, when taking in the air of a garage space in a heating apparatus, it will not take in exhaust gas, and it can be said that it is a preferable structure when implement | achieving 1st invention.

  As shown in FIG. 1, a building 10 such as a house is provided with a living space such as a living room 11 and a hallway 12, and a garage 13 that can park a vehicle. The living room 11 and the hallway 12 are partitioned by a partition wall 15. In the partition wall 15, an entrance / exit 16 that connects the living room 11 and the hallway 12 is formed, and a door 17 is provided in the entrance / exit 16.

  The lower end portion of the door 17 is undercut, and a ventilation portion 19 is formed between the door 17 and the floor surface 18. Air can be circulated between the living room 11 and the hallway 12 through the ventilation part 19. An opening may be formed in the partition wall 15 or the door 17 and the opening may be used as a ventilation portion 19 (vent hole).

  The garage 13 is a so-called inner garage provided integrally with the building 10. The interior of the garage 13 is a garage space 21, and the garage space 21 has a size capable of parking only one vehicle. The garage space 21 is surrounded by partition walls 22 to 24 on three sides. Among these partition walls 22 to 24, partition walls 22 and 23 are provided on both sides of the garage space 21, and a partition wall 24 is provided behind the garage space 21. The garage space 21 is partitioned from the corridor 12 by a partition wall 22 and partitioned from the outside by partition walls 23 and 24.

  A garage opening 25 as a vehicle entrance is formed on one side of the garage 13. Through this garage opening 25, the vehicle C and people can enter and leave the garage space 21. Although not shown in FIG. 1, the garage 13 is provided with a shutter device 64 (see FIG. 3) for opening and closing the garage opening 25. The shutter device 64 includes a shutter curtain 65 (see FIG. 3) that opens and closes the garage opening 25 by moving up and down.

  Here, in the present embodiment, a fuel cell vehicle (FCV) is assumed as the vehicle C parked in the garage space 21. That is, the vehicle C (fuel cell vehicle) is equipped with a fuel cell that generates power using hydrogen as a fuel and an electric motor (such as a motor) that is driven by the generated power generated by the fuel cell. It has become a vehicle that travels. Such a vehicle C has an advantage that no harmful exhaust gas is emitted.

  The floor 11 of the living room 11 and the hallway 12 (and consequently the living space) is higher than the floor 26 of the garage 13. In this case, an underfloor space 27 is formed below the living spaces 11 and 12. The underfloor space 27 is partitioned from the living spaces 11 and 12 vertically by a floor portion 28 that forms the floor surface 18 of the living spaces 11 and 12. Note that the floor portion 28 is configured to have a floor surface material such as a particle board.

  The underfloor space 27 is adjacent to the garage space 21 with the partition wall 22 therebetween. In this case, the partition wall 22 includes a wall portion 22 a that partitions the corridor 12 and the garage space 21, and a wall portion 22 b that partitions the underfloor space 27 and the garage space 21. The wall portion 22a is configured by having a wall surface material such as a plaster board, and the wall portion 22b is configured by a concrete foundation.

  An attic space 29 is formed above the living spaces 11 and 12 and the garage 13. In the building 10, an air conditioning system 30 for air conditioning the living space is constructed in the attic space 29. The air conditioning system 30 is configured as a whole-building air conditioning system that performs air conditioning of a plurality of living spaces using a common air conditioner 31. Below, the structure of this air conditioning system 30 is demonstrated.

  The air conditioning system 30 includes an air conditioner 31 and an intake duct 32 and an air supply duct 34 connected to the air conditioner 31. The intake duct 32 is connected to an intake grille 36 provided on the ceiling surface of the hallway 12, and the air supply duct 34 is connected to an air supply grille 38 provided on the ceiling surface of the living room 11. The intake duct 32 and the intake grill 36 form a second intake path.

  The air conditioner 31 includes a fan device 46 (see FIG. 2) therein. When the fan device 46 is operated, the air in the hallway 12 is taken in from the intake grill 36 and then taken into the air conditioner 31 through the intake duct 32. The air conditioner 31 generates conditioned air (warm air or cold air) by heating or cooling the air taken in by a heat exchange device (not shown). The conditioned air generated by the air conditioner 31 is supplied to the supply grill 38 through the supply duct 34 and then blown out from the supply grill 38 toward the living room 11. And the air conditioning (cooling / heating) of the living room 11 is performed by the blown-out air-conditioned air.

  Incidentally, in FIG. 1, only an air supply duct 34 (air supply grille 38) for supplying conditioned air to the living room 11 is shown as an air supply duct (and an air supply grille). An air supply duct (air supply grille) for supplying conditioned air to a living space other than the above is also connected to the air conditioner 31. Therefore, the conditioned air generated by the air conditioner 31 is also supplied to the living space other than the living room 11 through the air supply duct.

  The conditioned air supplied to the living room 11 flows into the hallway 12 through the ventilation part 19 below the door 17. The conditioned air is again taken into the air conditioner 31 via the intake grill 36 and the intake duct 32.

  Here, the garage space 21 in which the vehicle C can be parked is provided in the main building 10 as described above. In the garage space 21, when heat is exhausted from the vehicle C (for example, a fuel cell or a heat exhaust device provided to exhaust the heat of the fuel cell) immediately after the vehicle C enters the vehicle, It is conceivable that the internal air is warmed by heat. Therefore, the air conditioning system 30 is provided with a characteristic configuration that allows air in the garage space 21 to be taken into the air conditioner 31 during the heating operation of the air conditioner 31. According to this characteristic configuration, since the air in the garage space 21 warmed by the exhaust heat of the vehicle C can be taken into the air conditioner 31 to generate warm air, it is possible to improve heating efficiency. Therefore, in the following, this characteristic configuration will be described with reference to FIG. 2 in addition to FIG. FIG. 2 is a diagram showing an internal configuration of the air conditioner 31.

  As shown in FIG. 1, in addition to the above intake duct 32, an intake duct 33 is connected to the air conditioner 31. The intake duct 33 is connected to an intake grill 37 provided on the ceiling surface of the garage space 21. The intake duct 33 and the intake grill 37 form a first intake path.

  As shown in FIG. 2, the air conditioner 31 has a main body portion 31 a formed of a rectangular parallelepiped chamber. Two intake ports 41 and 42 are formed in the main body 31a. The intake port 41 is connected to the intake duct 32, and the intake port 42 is connected to the intake duct 33.

  The air conditioner 31 includes a damper portion 45 (damper mechanism) inside thereof (inside the main body portion 31a). The damper unit 45 includes an opening / closing plate 48 that opens and closes the intake port 42 and a drive unit 49 that drives the opening / closing plate 48 to open and close. The opening / closing plate 48 is provided so as to be rotatable with respect to the main body 31 a, and by the rotation, the closed state (the state shown in FIG. 2A) that closes the intake port 42 and the intake port 42 are opened. It is possible to shift to the open state (the state shown in FIG. 2B). In the closed state of the opening / closing plate 48, only the intake port 41 is opened, whereas in the opened state of the opening / closing plate 48, the two intake ports 41, 42 are opened.

  The drive part 49 consists of drive mechanisms, such as an electric motor. Although the drive part 49 is arrange | positioned inside the air conditioner 31, in FIG. 2, it has illustrated in the exterior of the air conditioner 31 for convenience.

  Here, when the fan device 46 is operated in the closed state of the opening / closing plate 48, the air in the hallway 12 is taken into the air conditioner 31 through the intake port 41 through the intake duct 32. On the other hand, the air in the garage space 21 is prohibited from being taken into the air conditioner 31 because the intake 42 is closed. On the other hand, when the fan device 46 is operated in the open state of the opening / closing plate 48, the air in the hallway 12 is taken into the air conditioning device 31 through the intake duct 32 and the air in the garage space 21 is taken in the intake duct 33. Through the intake 42 through the air conditioner 31.

  As described above, in the air conditioner 31, the mode in which the air is taken into the air conditioner 31 by the opening / closing operation of the opening / closing plate 48 (damper portion 45) is the second intake that takes in the air in the hallway 12 and does not take in the air in the garage space 21. It is possible to switch between a loading mode (see FIG. 2 (a)) and a first loading mode (see FIG. 2 (b)) that takes in the air in the hallway 12 and the air in the garage space 21, respectively. Therefore, during the heating operation of the air conditioner 31, the air in the garage space 21 can be taken into the air conditioner 31 by switching the air intake mode to the first intake mode. In this case, the damper portion 45 corresponds to the switching means.

  In a state where the air intake mode by the air conditioner 31 is the first intake mode, the conditioned air (warm air) supplied from the air conditioner 31 to the living room 11 is returned from the living room 11 to the garage space 21. Reflux through. The return air path 50 is formed using the underfloor space 27. The floor portion 28 that partitions the underfloor space 27 and the living room 11 is provided with a communication port 51 that allows the spaces 11 and 27 to communicate with each other. For example, a ventilation louver (not shown) is attached to the communication port 51. The communication port 51 corresponds to the first communication port. Further, the communication port 51 may be provided at a plurality of locations in the floor portion 28.

  The partition wall 22 (specifically, the wall portion 22b) that partitions the underfloor space 27 and the garage space 21 is provided with a communication port 53 that communicates both the spaces 21 and 27. The communication port 53 is formed in the height range of the vehicle C parked in the garage space 21, and is specifically formed in the lower part of the wall part 22b. The communication port 53 is formed at a position facing the vehicle C. When the vehicle C is parked in the garage space 21, the communication port 53 is opened toward the vehicle C. In addition, for example, a ventilation louver (not shown) is attached to the communication port 53. The communication port 53 corresponds to a second communication port. Moreover, the communication port 53 may be provided in multiple places in the wall part 22b.

  According to the above configuration, the conditioned air supplied to the living room 11 flows into the underfloor space 27 through the communication port 51, and then flows into the garage space 21 from the underfloor space 27 through the communication port 53. The air flowing into the garage space 21 is taken into the air conditioner 31 again via the intake grill 37 and the intake duct 33. The return air path 50 includes the communication ports 51 and 53 and the underfloor space 27.

  Next, the electrical configuration of the air conditioning system 30 will be described with reference to FIG. FIG. 3 is a diagram showing an electrical configuration of the air conditioning system 30.

  As shown in FIG. 3, the air conditioning system 30 includes a controller 60 as switching control means. The controller 60 is mainly composed of a known microcomputer having a CPU and the like. The controller 60 is built in the air conditioner 31, for example. The controller 60 has a timer 60a as a measuring means.

  The controller 60 is connected with a storage sensor 62 that detects that the vehicle C has entered the garage space 21. The warehousing sensor 62 includes an infrared sensor, and is provided on the partition wall 24 of the garage space 21, for example. The detection results are sequentially input from the warehousing sensor 62 to the controller 60.

  The controller 60 is connected to an operation unit 63 for performing operations on the air conditioning system 30 (air conditioner 31). The operation unit 63 is provided, for example, on the partition wall of the living room 11.

  A fan device 46, a drive unit 49, and a shutter device 64 are connected to the controller 60. The controller 60 controls the operation of the fan device 46 based on the operation of the operation unit 63. The controller 60 controls the operation of the drive unit 49 and the shutter device 64 based on the detection result of the warehousing sensor 62.

  Next, the heating control process executed by the controller 60 during the heating operation of the air conditioning system 30 (air conditioner 31) will be described. FIG. 4 is a flowchart showing the heating control process. In addition, this process is repeatedly performed with a predetermined period at the time of the heating operation of the air conditioner 31.

  As shown in FIG. 4, first, in step S <b> 11, it is determined based on the detection result from the warehousing sensor 62 whether or not the vehicle C has entered the garage space 21. If the vehicle C has not entered, this process is terminated. When the vehicle C is received, the process proceeds to step S12.

  In step S12, it is determined whether or not the shutter curtain 65 is in a closed state. That is, after the vehicle C enters the garage space 21, it is determined whether or not the shutter curtain 65 is closed. This determination is performed based on an open / close signal input from the shutter device 64, for example. If the shutter curtain 65 is in the closed state, the process proceeds to step S13. On the other hand, when the shutter curtain 65 is in the open state, step S12 is repeated until the shutter curtain 65 is closed.

  In step S13, the 1st switching process which switches the air intake mode to the air conditioner 31 to a 1st intake mode is performed. In this process, the open / close plate 48 is opened by outputting an open signal to the drive unit 49. Thereby, the air of the garage space 21 is taken into the air conditioner 31 together with the air of the hallway 12. For this reason, the air of the garage space 21 warmed by the exhaust heat of the vehicle C immediately after warehousing is taken into the air conditioner 31.

  In step S14, timing by the timer 60a is started. In a succeeding step S15, it is determined whether or not an elapsed time after the timer 60a starts measuring a predetermined time.

  Here, the exhaust heat from the vehicle C entering the garage space 21 decreases as time passes. As a result, the air in the garage space 21 cannot be warmed due to the exhaust heat of the vehicle C. Therefore, in step S15, the predetermined time is set to a time shorter than the time from when the vehicle C enters the warehouse until the garage space 21 cannot be warmed by the exhaust heat of the vehicle C. For example, the predetermined time is set to 30 minutes. Therefore, in this step S15, in short, it is determined whether or not the garage space 21 is warmed by the exhaust heat of the vehicle C (predetermined warm-up state). In step S15, if the elapsed time by the timer 60a has passed a predetermined time, the process proceeds to step S16. On the other hand, if the elapsed time by the timer 60a has not passed the predetermined time, step S15 is repeated until the predetermined time has passed.

  In step S16, the 2nd switching process which switches the air intake mode to the air conditioner 31 to a 2nd intake mode is performed. In this process, the open / close plate 48 is closed by outputting a close signal to the drive unit 49. Thereby, only the air of the corridor 12 is taken in by the air conditioner 31, and the air of the garage space 21 is not taken in. Therefore, it is possible to avoid the air in the garage space 21 that has cooled down after the exhaust heat state of the vehicle C has been taken into the air conditioner 31.

  In addition, although illustration is abbreviate | omitted, also when it is detected that the shutter curtain 65 (shutter apparatus 64) opened during said step S13-S15, it progresses to step S16 and air to the air conditioner 31 is carried out. The process which switches the uptake | capture mode of this to a 2nd uptake | capture aspect is performed.

  In continuing step S17, based on the detection result from the warehousing sensor 62, it is determined whether the vehicle C left the garage space 21 or not. This process is complete | finished when the vehicle C leaves. If the vehicle C has not left, this step is repeated until the vehicle C leaves.

  As mentioned above, according to the structure of this embodiment explained in full detail, the following outstanding effects are acquired.

  As a take-in route for taking air into the air conditioner 31, a first take-in route (specifically, a take-in duct 33 and the like) for taking air in the garage space 21 was provided. In this case, since the air in the garage space 21 heated by the exhaust heat of the vehicle C can be taken into the air conditioner 31 through the intake duct 33, the heating efficiency can be improved. Further, when the exhaust heat of the vehicle C is taken into the air conditioner 31, it is not necessary to connect the vehicle C side and the building 10 side (for example, the air conditioner 31) with a connecting pipe, and heat is applied to the vehicle C side and the building 10 side. There is no need for a large-scale configuration such as constructing a medium path. Accordingly, it is possible to improve the heating efficiency without trouble with a relatively simple configuration.

  Switching the air intake mode to the air conditioner 31 between the garage space 21 and the corridor 12 (first intake mode) and the air intake mode (second intake mode) only from the corridor 12 It was possible. In this case, when the garage space 21 is heated by the exhaust heat of the vehicle C, the first intake mode is switched to take in warm air in the garage space 21, and the vehicle C is parked in the garage space 21. If the garage space 21 is in a cold state, the air can be taken in only from the corridor 12 by switching to the second intake mode. In this case, since it can be switched whether or not the air in the garage space 21 is taken in depending on whether or not the garage space 21 is heated by the exhaust heat of the vehicle C, it can be said to be a practically preferable configuration.

  When the garage space 21 is in a state heated by exhaust heat of the vehicle C (predetermined warm-up state), the air intake mode to the air conditioner 31 is switched to the first intake mode. In this case, since warm air in the garage space 21 is taken into the air conditioner 31, the heating efficiency can be improved. On the other hand, when the garage space 21 is not in the warm air state, the air intake mode of the air conditioner 31 is switched to the second intake mode. In this case, since air is taken into the air conditioner 31 only from the corridor 12, it is possible to prevent cold air in the garage space 21 from taking in and causing a decrease in heating efficiency.

  By the way, immediately after the vehicle C enters the garage space 21, it is considered that the garage space 21 is warmed by the exhaust heat of the stored vehicle C. Therefore, in the above embodiment, in view of this point, the elapsed time after the vehicle C enters the garage space 21 is measured by the timer 60a, and the garage space 21 is in a predetermined warm-up state based on the measured elapsed time. Judgment was made whether or not. In this case, it can be suitably determined whether or not the garage space 21 is in a warm state.

  A communication port 51 for communicating the living room 11 and the underfloor space 27 is provided in the floor portion 28, and a communication port 53 for communicating the garage space 21 and the underfloor space 27 is provided in the wall portion 22b. In this case, the warm air supplied to the living room 11 flows into the underfloor space 27 through the communication port 51, and then flows into the garage space 21 from the underfloor space 27 through the communication port 53. Here, since the communication port 53 is formed in the height range of the vehicle C parked in the garage space 21, in this case, the warm air flowing into the garage space 21 from the communication port 53 passes through the periphery of the vehicle C. The intake duct 33 and thus the air conditioner 31 are taken in. Therefore, the exhaust heat of the vehicle C can be suitably taken into the air conditioner, and as a result, the heating efficiency can be further improved.

  Since the vehicle C parked in the garage space 21 is a fuel cell vehicle that travels using the electric power generated by the fuel cell, exhaust gas is not taken in when the air in the garage space 21 is taken into the air conditioner 31. Therefore, it is convenient to implement the above-described configuration in which the air in the garage space 21 is taken in to improve the heating efficiency.

  The present invention is not limited to the above embodiment, and may be implemented as follows, for example.

  (1) In the above embodiment, whether or not the garage space 21 is in a predetermined warmed state due to the exhaust heat of the vehicle C is determined based on the elapsed time from the warehousing of the vehicle C, but this is changed. Also good. For example, a garage temperature sensor that detects the temperature of the garage space 21 may be provided, and the above determination may be performed based on the temperature of the garage space 21 detected by the sensor. In this case, even when the vehicle C is exhausting heat other than immediately after entering the garage space 21, it can be determined that the garage space 21 is in a warm state due to the exhaust heat.

  (2) In the above embodiment, when the air intake mode to the air conditioner 31 is the first intake mode, the air in the corridor 12 is taken together with the air in the garage space 21, but this is changed. Then, in the first intake mode, only the air in the garage space 21 may be taken in. In this case, when the temperature of the garage space 21 is higher than the temperature of the corridor 12, only the air in the warmer garage space 21 can be taken into the air conditioner 31, thereby further improving the heating efficiency. Can do. In order to take in only the air in the garage space 21, for example, the opening / closing plate 48 may be rotated to a closed position where the inlet 41 is closed.

  (3) When the air intake mode to the air conditioner 31 is the first intake mode, the amount of air taken into the air conditioner 31 from the garage space 21 may be adjustable. Moreover, when the air intake mode to the air conditioner 31 is the first intake mode, the amount of air taken into the air conditioner 31 from the garage space 21 and the amount of air taken from the corridor 12 can be adjusted. Also good. In this case, the amount of air taken in from the spaces 12 and 21 can be set to an appropriate amount according to the temperature of the garage space 21 and the temperature of the corridor 12, so that the heating efficiency of the air conditioner 31 can be improved. This can be suitably achieved. In addition, as a structure (adjustment means) which adjusts the air intake amount from each space 12 and 21, the structure which adjusts these each air intake amount by adjusting the angle of the opening-and-closing plate 48 can be considered.

  Further, in this case, the building 10 is provided with a garage temperature sensor for detecting the temperature of the garage space 21 and a hallway temperature sensor for detecting the temperature of the hallway 12, and the controller 60 detects the garage space 21 detected by each sensor. Control of adjusting the air intake amount from the spaces 12 and 21 by the adjusting means may be performed based on the comparison result between the temperature of the corridor 12 and the temperature of the corridor 12. For example, when the temperature of the garage space 21 is higher than the temperature of the hallway 12, it can be considered to control the air intake amount from the garage space 21 to be increased.

  Furthermore, the controller 60 may perform the above-described control in consideration of the heating set temperature of the air conditioner 31.

  (4) You may enable it to perform switching (switching to either the 1st taking in mode or the 2nd taking in mode) about the mode of taking in air to air-conditioner 31 based on operation by operation part 63.

  (5) In the above embodiment, the air conditioner 31 is provided in the attic space 29, but the air conditioner 31 is not necessarily provided in the attic space 29. For example, as shown in FIG. 5A, the air conditioner 31 may be provided in the underfloor space 27. In the example of the figure, of the two intake ducts 72 and 73 connected to the air conditioner 71, the intake duct 72 is connected to an intake grill 74 provided on the floor 18 of the hallway 12, and the intake duct 73 is connected to an intake grill 75 provided on the wall surface of the wall portion 22 b of the garage space 21. In this case, the air in the hallway 12 is taken into the air conditioner 71 via the intake grill 74 and the intake duct 72, and the air in the garage space 21 is taken into the air conditioner 71 via the intake grill 75 and the intake duct 73. It is.

  The air supply duct 76 connected to the air conditioner 71 is connected to an air supply grill 77 provided on the floor 18 of the living room 11. In this case, the conditioned air generated by the air conditioner 71 is supplied to the living room 11 via the air supply duct 76 and the air supply grill 77. The conditioned air supplied to the living room 11 is taken into the corridor 12 through the vent 79 formed in the partition wall 15 and taken into the garage space 21 through the return air path 50 (the communication ports 51 and 53 and the underfloor space 27). Therefore, also in the configuration of this example, the same effect as in the above embodiment can be obtained.

  In addition, as shown in FIG. 5B, an air conditioner 81 may be provided in the hallway 12. In the example shown in the figure, the air conditioner 81 is provided with two intakes 82 and 83, and the intake 82 of the two intakes 82 and 83 leads to the hallway 12. 83 communicates with the garage space 21 through the partition wall 22. In this case, the air in the corridor 12 and the air in the garage space 21 are taken into the air conditioner 81 through the intakes 82 and 83, respectively.

  The air conditioner 81 is provided with an air supply port 85. The air supply port 85 communicates with the living room 11 through the partition wall 15. In this case, the conditioned air generated by the air conditioner 81 is supplied to the living room 11 from the air supply port 85. The conditioned air supplied to the living room 11 flows into the corridor 12 and the garage space 21 through the same route as in the case of FIG. Therefore, also in the configuration of this example, the same effect as in the above embodiment can be obtained.

  (6) In the above embodiment, the heating system of the present invention is applied when the vehicle C parked in the garage space 21 is a fuel cell vehicle. However, the vehicle C parked in the garage space 21 is not a fuel cell vehicle. The present invention can also be applied to an electric vehicle. For example, it is conceivable to apply the present invention when the vehicle C is a secondary battery type electric vehicle equipped with a storage battery for storing electric power and an electric motor driven by the electric power stored in the storage battery. Also in this case, since the exhaust gas is not emitted from the vehicle C, the exhaust gas is not taken in when the air in the garage space 21 is taken into the air conditioner 31.

  Further, the present invention may be applied when the vehicle C parked in the garage space 21 is a vehicle other than an electric vehicle. For example, the present invention may be applied when the vehicle C is a vehicle that travels using an internal combustion engine such as a gasoline engine or a diesel engine as a power source. In this case, for example, exhaust heat released from a radiator of the vehicle can be used. However, since the vehicle C emits exhaust gas, in this case, an air filter is provided in the intake duct 33 or the like, and the air in the garage space 21 is taken into the air conditioner 31 through the air filter. Is desirable. Further, a discharge device (discharge pipe or the like) for discharging the exhaust gas outside the garage may be connected to the exhaust pipe of the vehicle, and the exhaust gas may be guided outside the garage via the discharge device.

  (7) A case where a plurality of types of vehicles C are parked in the garage space 21 is also assumed. For example, it is assumed that a fuel cell vehicle (battery vehicle) is parked in the garage space 21 or a gasoline vehicle equipped with a gasoline engine is parked. In other words, it is assumed that a vehicle (non-exhaust vehicle) that does not emit exhaust gas to the garage space 21 and a vehicle (exhaust vehicle) that emits exhaust gas are parked. Therefore, in consideration of such a case, vehicle determination means for determining whether or not the vehicle parked in the garage space 21 is an exhaust gas vehicle is provided, and the vehicle determination means determines that the vehicle is an exhaust gas vehicle. In this case, the controller 60 may switch the air intake mode to the air conditioner 31 to the second intake mode regardless of whether the garage space 21 is in a predetermined warm-up state. In this case, when the exhaust gas vehicle is parked in the garage space 21, the intake of the air in the garage space 21 into the air conditioner 31 is prohibited, so that the exhaust gas of the vehicle can be prevented from being taken into the air conditioner 31.

  For example, the following configuration can be considered as the vehicle determination means. A transmission unit that transmits identification information for identifying a vehicle type (exhaust gas vehicle or non-exhaust vehicle) is provided on the vehicle side, and a vehicle parked in the garage space 21 is provided on the building 10 side (for example, the garage space 21). A receiving unit is provided for receiving the transmitted identification information. And the controller 60 determines whether the vehicle parked in the garage space 21 is an exhaust gas vehicle based on the identification information received through the receiver.

  The following configuration is also conceivable. As the control mode during the heating operation by the air conditioner 31, an exhaust gas vehicle mode and a non-exhaust vehicle mode are provided, and can be set to any of these modes based on an operation by the operation unit 63. In this case, the user sets the control mode to the exhaust gas mode when the exhaust gas vehicle enters the garage space 21, while the control mode is set to the non exhaust gas mode when the non-exhaust vehicle enters the garage space 21. Set. Then, the controller 60 determines whether or not the vehicle stored in the garage space 21 is an exhaust gas vehicle based on the control mode set by the operation unit 63.

  (8) For example, when the commercial power supply in the building 10 cannot be used due to a power failure or the like, it is conceivable to generate power with the fuel cell of the vehicle C and supply the generated power to the building 10 side. In such a case, the fuel cell generates heat as the fuel cell generates power. In this case as well, the air in the garage space 21 can be taken in and used for heating.

  Further, when the fuel cell generates power, water is generated in the fuel cell and the water is discharged from the vehicle. Therefore, it is assumed that the humidity of the garage space 21 is appropriately increased by the discharged water. The Therefore, in this case, if the air in the garage space 21 is taken in and heated, not only the heating effect is improved but also the effect of suppressing the drying in the living room 11 can be expected.
