Description

  The present invention relates to a building and an airflow control system.

In recent years, it has been desired to reduce energy consumption in buildings such as houses from the viewpoints of economy and environmental protection, and various technologies for energy reduction have been proposed. For example, a technique has been proposed in which energy is stored in a heat storage unit using solar heat or geothermal heat, and air-conditioning in a building is performed using the energy (see, for example, Patent Document 1).
JP 2004-69271 A

  However, in existing technologies including the above-mentioned Patent Document 1, the heat stored in the heat storage section (heating and cooling tower section in the above-mentioned Patent Document 1) is released into the building and can be used for heating or the like. The possible range is basically limited to the room adjacent to the heat accumulator. For this reason, there is not enough countermeasures for how to efficiently heat other rooms (rooms not adjacent to the heat storage part) provided in the building, and therefore there is room for countermeasures. It is done.

  The main object of the present invention is to provide a building and an airflow control system that can effectively use heat generated in the building, and thereby improve energy efficiency in the building.

  Hereinafter, means and the like effective for solving the above-described problems will be described while showing functions and effects as necessary. In the following, in order to facilitate understanding, a corresponding configuration example in the embodiment of the invention is appropriately shown in parentheses, etc., but is not limited to the specific configuration shown in parentheses.

  The building (building 10) of the present invention is provided with a low floor space (dining kitchen 12) and a high floor space (rooms 21 to 24) having a floor position higher than the low floor space adjacent to each other in the horizontal direction. In addition, a heat source facility (kitchen facility 16) that generates heat is provided in the low floor space portion, and an opening (opening) that connects the heat generated by the heat source device to the low floor space portion and the high floor space portion. It is configured to move to the raised floor space through the portions 21b to 24b).

  According to the above configuration, the heat source equipment is provided in the low floor space portion, and the high floor space portion is provided adjacent to the low floor space portion in the horizontal direction, and the heat generated in the low floor space portion is the same as the low floor space portion. It rises in the interior and flows into the high floor space through the opening. Thereby, the heat generated by the heat source facility in the low floor space can be efficiently used for warming up the high floor space. As a result, it is possible to effectively use the heat generated in the building, thereby improving the energy efficiency in the building.

  The high floor space is preferably provided so as to surround the low floor space. According to this, the space part (low floor space part) which has a heat source facility will be enclosed by other space parts (high floor space part), and it will be suppressed that a heat | fever escapes wastefully outdoors, a low floor The heat insulation effect in the space can be expected. In addition, when the high floor space portion is arranged around the low floor space portion, heat transfer is performed with respect to an arbitrary high floor space portion (for example, any of the plurality of high floor space portions). However, it becomes easy to set the heat transfer site, which is a convenient configuration.

  It is preferable that the high floor space part is provided so as to partially overlap the low floor space part in the height direction, and the opening is provided in a partition wall that partitions the low floor space part and the high floor space part. Thereby, it becomes a structure where airflow tends to be generated from the low floor space portion toward the high floor space portion, and heat transfer can be performed efficiently.

  Here, the low-floor space part is a blowout that continuously connects a lower floor part configured on the basis of the floor surface of the low-floor space part and an upper floor part configured on the basis of the floor surface of the high-floor space part. It should be a space.

  It is preferable to provide heat insulating means on at least one of the ceiling portion of the low floor space portion and the surrounding partition. In this case, in a portion where the low floor space portion and the high floor space portion are adjacent to each other, a heat insulating means may be provided on the partition wall that partitions both the space portions. Thereby, the heat loss in the low floor space can be reduced, and the thermal efficiency is further improved.

  For example, in a building having a roof portion (or a rooftop) directly above the low floor space portion, heat insulation means may be applied to the roof portion. In particular, in a building having a flat roof directly above the low floor space part, it is desirable to realize rooftop insulation by using a rooftop garden as a rooftop garden.

  A plurality of the high floor space portions are provided adjacent to the low floor space portion, the openings are provided for each of the high floor space portions, and the openings for the high floor space portions can be selectively opened and closed. Thereby, it becomes possible to warm up only about the high floor space part which a user desires among several high floor space parts. Therefore, the comfort for the user in the building is improved.

  The heat source facility is preferably a kitchen facility (kitchen facility 16) having a heating cooker or the like. In this case, the high floor space can be efficiently warmed using the heat generated in the kitchen facility. When the high floor space portion is provided so as to surround the low floor space portion, the kitchen is surrounded by the high floor space portion, and it is suppressed that the heat of the kitchen (including the dining kitchen with integrated dining) escapes to the outdoors. Therefore, the heat insulation effect in the kitchen can be expected.

  When the kitchen is surrounded by the high floor space as described above, in other words, the kitchen is installed in the center of the building.

  Here, the case where the low floor space part is a kitchen (dining kitchen) and the high floor space part is a room of each user is considered. In this case, it is assumed that each user moves to his / her own room after having a meal in the kitchen (dining kitchen). However, according to the above configuration, the user can move from the kitchen (dining kitchen) to the living room. In addition, heat can be transferred from the kitchen (dining kitchen) to the living room. Therefore, a practically desirable configuration can be realized.

  In the building configured as described above, it is desirable to apply the following airflow control system. That is, the airflow control system is provided in the opening, and an opening / closing member (opening / closing members 21c to 24c) that opens and closes the opening, and heat generated by the heat source facility is transferred from the low floor space to the high floor space. Control means (controller 50) for executing opening / closing control of the opening / closing member so as to move to the position.

  According to the above configuration, the opening / closing member is automatically opened and closed by the control means, whereby an air flow can be generated from the low floor space portion to the high floor space portion, and heat transfer from the low floor space portion to the high floor space portion. Is done. Therefore, it becomes possible for the user to warm the high floor space portion conveniently.

  As specific contents of the airflow control, the following methods (1) to (3) can be applied. The airflow control may be executed by any one of these methods or a combination thereof.

  (1) A determination unit (human sensors 44 to 46 and controller 50) for determining the presence or absence of a person in the high floor space portion is provided, and the opening / closing member is opened based on the presence or absence of a person in the high floor space portion. For example, in winter, when it is determined that there is a person in the high floor space, the opening / closing member is opened. Thereby, when there is no person in the high floor space part, it can suppress performing warming wastefully. In the summer, contrary to the above, when it is determined that there is no person in the high floor space, the opening / closing member is opened. Thereby, it can suppress that the person in a high-floor space part learns discomfort by hot air.

  (2) A time zone for air conditioning is determined in advance for the high floor space, and the opening and closing member is opened in the time zone for air conditioning. Thereby, it becomes possible to warm the high floor space before the person actually moves to the high floor space.

  (3) Temperature difference detection means (temperature sensors 41 to 43 and controller 50) for detecting a temperature difference between the low floor space and the high floor space is provided, and the opening / closing member is opened based on the temperature difference. For example, when the temperature difference ΔT (= low floor side temperature−high floor side temperature) between the low floor space and the high floor space is a predetermined determination value (for example, 5 ° C.), the opening / closing member is opened. Thereby, the heat in the low floor space can be effectively used in the high floor space.

  In addition, in a building having a plurality of high floor space portions adjacent to the low floor space portion, each opening / closing member of the opening provided in each of the plurality of high floor space portions may be selectively opened or closed. Thereby, the warm air by the heat | fever in the low floor space part can be performed separately about a some high floor space part, and the comfort for the user in a building improves further.

  Further, in the high floor space portion, an outdoor side opening / closing body (sash doors 61, 62, 74, 76) is provided at the opening of the outer wall that separates the high floor space portion from the outdoor space, and the house is opened in accordance with the opening of the opening / closing member. The outer opening / closing body may be opened. Thereby, in the high floor space part, inflow of air from the low floor space part side and discharge of air to the outdoor side are performed simultaneously, and generation of airflow in the high floor space part can be promoted. Therefore, the heat flowing into the high floor space part together with the rising air flow from the low floor space part can be propagated in the horizontal direction (horizontal direction) in the high floor space part, and accordingly, the warm air in the high floor space part can be efficiently performed.

  Here, the opening / closing member and the outdoor-side opening / closing body (for example, the sash door 73 and the sash door 74 in FIG. 7) located in a position sandwiching an area to be warmed in the high floor space portion may be opened as control targets. . Thereby, a warm air flow can be produced in the area which should be warmed each time, and a suitable warm air can be performed about the area.

  An airflow generating means (blowers 77 and 78) for generating a horizontal airflow is provided in the raised floor space portion, and the airflow in the elevated floor space portion is generated by the airflow generating means in controlling the opening and closing of the opening and closing member. preferable. Thereby, an air flow can be generated more actively and in a wide area in the high floor space portion, and warm air in the high floor space portion can be suitably performed.

In this embodiment, an example in which the present invention is applied to a three-story detached house will be described. FIG. 1 is a drawing showing a longitudinal section of a building 10, and FIG. 2 is a plan view showing a floor plan of a first floor portion, a second floor portion, and a third floor portion (a rooftop floor portion) of the building 10. 1 corresponds to a cross-sectional view taken along line AA in FIG.

  In the building 10, the entrance hall 11, the dining kitchen 12, the living rooms 13, 14 and the toilet 15 are provided on the first floor. The dining kitchen 12 is provided substantially in the center of the building 10, and the entrance hall 11, the living rooms 13 and 14, the toilet 15 and the like are arranged so as to surround the dining kitchen 12. The dining kitchen 12 is an atrium space that continues on the first floor and the second floor. In addition, on the floor of the dining kitchen 12, a kitchen facility 16 including a gas stove, an electromagnetic cooker, a heating cooking device 16a such as an oven, and a sink 16b is installed. In addition, the dining kitchen 12 is provided with stairs 17 and 18 leading to the second floor portion. For the sake of convenience, the illustration of openings (exit entrances and the like) leading to the respective spaces on the first floor is omitted.

  In addition, in the second floor portion, living rooms 21, 22, 23, and 24 are provided so as to surround the second floor atrium of the dining kitchen 12. That is, each living room 21 to 24 is provided adjacent to the second floor atrium of the dining kitchen 12 in the horizontal direction. Each of the living rooms 21 to 24 is, for example, a room allocated to each resident. Each of the living rooms 21 to 24 is provided with movable or detachable partition walls 21a, 22a, 23a, and 24a, and each of the living rooms 21 to 24 is divided into two by mounting each of the partition walls 21a to 24a. Then, by removing the partition walls 21a to 24a, the room size of each of the living rooms 21 to 24 can be expanded. In the present embodiment, the dining kitchen 12 corresponds to a “low floor space portion”, and the living rooms 21 to 24 correspond to “high floor space portions”.

  In the living rooms 21 and 24, entrances 21b and 24b for entering and exiting between the staircase floors 25 and 26 on the second floor and the living room are formed, and doors 21c and 24c are provided in the entrances 21b and 24b. In addition, windows 22b and 23b are formed in the partition wall that separates the living rooms 22 and 23 from the second floor atrium of the dining kitchen 12, and sash doors 22c and 23c such as glass doors are provided in the windows 22b and 23b. . As the sash doors 22c and 23c, a sliding type, an extrusion type, a single opening type, or the like can be adopted. In the following description, the doorways 21b, 24b and the windows 22b, 23b are also referred to as “openings 21b-24b”, and the doors 21c, 24c and the sash doors 22c, 23c are also referred to as “opening / closing members 21c-24c”. In FIG. 2, the entrances to the living rooms 22 and 23 are not shown.

  Each of the living rooms 21 to 24 is an open space that continues on the second and third floors, and lofts 31, 32, 33, and 34 are provided on the third floor.

  The dining kitchen 12 can be expected to have a heat insulating effect by being provided in the approximate center of the building 10. Further, in order to further enhance the heat insulating property, a high heat insulating material is disposed on the partition wall between the dining kitchen 12 and each room surrounding the dining kitchen 12. In addition, high heat insulating materials are also disposed on the walls around each of the rooms 21 to 24.

  A rooftop floor 35 is provided above the dining kitchen 12 in the third floor portion (rooftop). In the main building 10, the rooftop floor 35 is a rooftop garden, and lawns and various plants are planted almost on the entire floor. By using the rooftop floor 35 as a rooftop garden, high insulation is achieved at the ceiling of the dining kitchen 12.

  FIG. 3 is a perspective view schematically showing the exterior of the main building 10. As shown in FIG. 3, the building 10 is roughly divided into a central block B1 constituting the dining kitchen 12, and surrounding blocks B2 and B3 having respective rooms on the first to third floors. These are constructed so as to be surrounded by surrounding blocks B2 and B3 having an L shape in plan view. That is, the dining kitchen 12 is installed in the center of the building.

  In this embodiment, in the building 10, the heat generated by the kitchen equipment 16 (heating cooking equipment 16a) of the dining kitchen 12 is appropriately moved to each room on the second floor to effectively use the heat. Perform airflow control for heat transfer. Details will be described below.

  FIG. 4 is a diagram illustrating an electrical configuration of the airflow control system. In FIG. 4, for convenience of explanation, the system configuration is shown only for the dining kitchen 12 and the living rooms 22 and 23 on the second floor adjacent thereto. The other rooms 21 and 24 on the second floor will be omitted because they are redundantly described.

  In FIG. 4, temperature sensors 41, 42, and 43 are respectively provided in the dining kitchen 12 and the living rooms 22 and 23 on the second floor, and temperature information detected by these sensors 41 to 43 is appropriately input to the controller 50. Is done. Similarly, the dining kitchen 12 and the living rooms 22 and 23 on the second floor are provided with human sensors 44, 45 and 46, respectively, and human detection information detected by the sensors 44 to 46 is appropriately input to the controller 50. Is done. The sash doors 22c and 23c provided in the respective living rooms 22 and 23 are provided with motors 47 and 48 as drive actuators, and the sash doors 22c and 23c are opened and closed by driving the motors 47 and 48. It is like that.

  In addition to the detection signals of the respective sensors described above, information related to the usage status of the kitchen facility 16 is input to the controller 50. For example, heat source information indicating that the cooking device 16a, which is a heat source, is being operated (ie, being cooked) is input.

  The controller 50 is an arithmetic unit having a known microcomputer including a CPU, a memory, and the like, and executes opening / closing control of the sash doors 22c and 23c based on the detection signals of the sensors 41 to 46 described above.

  Further, in this embodiment, the opening / closing control is also executed for the sash doors of ventilation windows (not shown in FIGS. 1 and 2 described above) provided in each room, and FIG. 4 shows the upper part of the rooms 22 and 23. The sash doors 61 and 62 of the ventilation window provided in (the height of the 3rd floor part) and the motors 63 and 64 which drive the sash doors 61 and 62 to open and close are shown. The controller 50 appropriately executes opening / closing control for the sash doors 61 and 62 of the ventilation window in accordance with the opening / closing control of the sash doors 22c and 23c.

  FIG. 5 is a flowchart showing a processing procedure of airflow control, and this processing is executed by the controller 50 at a predetermined time period. This process shows airflow control when each room 21-24 on the second floor is actively warmed up in winter or the like. Here, for convenience, only the dining kitchen 12 and the living rooms 22 and 23 on the second floor will be described.

  In FIG. 5, in step S11, temperature information of each room is acquired. That is, the indoor temperature T1 of the dining kitchen 12, the indoor temperature T2 of the living room 22, and the indoor temperature T3 of the living room 23 are calculated based on the detection signals of the temperature sensors 41 to 43. In step S12, the occupancy status of the dining kitchen 12 and the living rooms 22 and 23 on the second floor is monitored based on the detection signals of the human sensors 44 to 46.

  Thereafter, in step S13, the room temperature T1 of the dining kitchen 12 is compared with a predetermined reference temperature REF to determine whether or not T1> REF. The reference temperature REF is a temperature for determining whether the heat staying in the dining kitchen 12 can be used in another room, and is a temperature value of about 20 ° C., for example. Then, subsequent processing is executed on condition that T1> REF. Instead of the determination of “T1> REF?”, It is also possible to determine whether the cooking device 16a has been continuously operated for a predetermined time or more.

  If step S13 is NO, this process is terminated as it is. That is, the sash doors 22c and 23c of the living rooms 22 and 23 are not opened. If step S13 is YES, the process proceeds to the subsequent step S14.

  In steps S14 to S16, an opening / closing process of the sash door 22c is executed for the living room 22. That is, in step S14, the indoor temperature T1 of the dining kitchen 12 and the indoor temperature T2 of the living room 22 are compared to determine whether T1> T2 + α (for example, α = 5 ° C.). In step S15, it is determined whether there is a person in the living room 22. And if both step S14 and S15 are YES, it will progress to step S16 and will open the sash door 22c of the living room 22. FIG.

  In steps S17 to S19, the sash door 23c is opened and closed for the living room 23. That is, in step S17, the room temperature T1 of the dining kitchen 12 and the room temperature T3 of the living room 23 are compared to determine whether T1> T3 + β (for example, β = 5 ° C.). In step S18, it is determined whether or not there is a person in the living room 23. And if both step S17 and S18 are YES, it will progress to step S19 and will open the sash door 23c of the living room 23. FIG.

  When the conditions for opening the sash doors are established for both the living rooms 22 and 23, a configuration may be adopted in which either one is preferentially warmed up. For example, the one with the lower room temperature is preferentially warmed (that is, the sash door is opened). Alternatively, either of the rooms 22 and 23 is warmed based on a predetermined priority order (that is, the sash door is opened).

  The predetermined values α and β used for the temperature determination in steps S14 and S17 may be α = β, but α ≠ β may also be used. By setting α ≠ β, it is possible to preferentially warm one of the living rooms 22 and 23. That is, if α> β, for example, step S17 is more easily established than step S14, and warming is performed with priority for the living room 23.

  In the flowchart of FIG. 5, a step of determining whether or not there is a person in the dining kitchen 12 (whether or not it remains) is added. If there is a person in the dining kitchen 12, the sash doors 22 c and 23 c of the living rooms 22 and 23 are displayed. It is good also as a structure which does not open. Thereby, the dining kitchen 12 is hold | maintained in the state kept warm.

  The generation | occurrence | production state of the airflow in the building 10 is demonstrated using FIG.

  6A shows a case where T1 ≦ REF, T1 ≦ T2 + α and T1 ≦ T3 + β, or a case where there is no one in the living rooms 22 and 23. In such a case, each of the living rooms 22 and 23 is shown. Both sash doors 22c and 23c are closed. Thereby, the ascending air current, that is, heat transfer from the dining kitchen 12 to the living rooms 22 and 23 does not occur.

  On the other hand, (b) has shown the case where the opening condition of the sash door about the living room 22 is materialized, In this case, the sash door 22c of the living room 22 is opened. As a result, an upward air flow from the dining kitchen 12 to the living room 22 is generated, and the living room 22 is warmed by the accompanying heat transfer. In addition, when airflow is generated as shown in the figure, it is possible to open the sash door 61 of the ventilation window, thereby urging the generation of airflow.

  Further, (c) shows a case where the sash door opening conditions for the living rooms 22 and 23 are both established. In such a case, the sash doors 22c and 23c of the living rooms 22 and 23 are both opened. The Thereby, ascending airflow is generated from the dining kitchen 12 to the living room 22 and the dining kitchen 12 to the living room 23, and the living rooms 22 and 23 are warmed by the accompanying heat transfer. When airflow is generated as shown in the figure, it is also possible to open the sash doors 61 and 62 of the ventilation window, thereby encouraging the generation of airflow.

  As shown in FIG. 5 described above, the behavior of each user (resident) is predicted in addition to performing airflow control on the condition that there is actually a person in each of the rooms 22 and 23 and heating the second-floor room. Thus, it is possible to warm the second-floor room by performing airflow control before a person moves to each of the rooms 22 and 23.

  Specifically, airflow control is executed according to the time of day. For example, when each resident gathers and eats at the dining kitchen 12 at dinner, the resident is supposed to return to his / her room after finishing the meal. Therefore, it is preferable to set a time schedule that heats the second-floor room after dinner, and to execute airflow control in the building based on the time schedule. It is desirable to set the warm-up time zone for each room. As a specific example, in the dinner time zone (pm 7:00 to 8:00) where residents gather in the dining kitchen 12 for dinner, the state shown in FIG. 6A is set, and the time zone after dinner (pm 8:00) ˜9: 00), the state shown in FIG. 6B or 6C is assumed. Or you may make it warm each room 21-24 according to a resident's bedtime.

  In the summer, contrary to the winter, the heat transfer from the dining kitchen 12 to the living rooms 22 and 23 is inconvenient when there are people in each of the living rooms 22 and 23. Therefore, the conditions for opening the sash doors are different.

  For example, when it is determined that there is no person in each of the living rooms 22 and 23, the sash door is opened, and heat is transferred from the dining kitchen 12 to the living rooms 22 and 23. Thereby, the heat in the dining kitchen 12 can be released through the living rooms 22 and 23. At this time, if there is a person in each of the living rooms 22 and 23, the above-described heat transfer is not performed, so that it is possible to prevent the person in each of the living rooms 22 and 23 from feeling uncomfortable due to hot air.

  According to the embodiment described in detail above, the following excellent effects can be obtained.

  In the building 10, the heat generated in the dining kitchen 12 is transferred to the living rooms 21 to 24 through the openings 21 b to 24 b that communicate the dining kitchen 12 and the living rooms 21 to 24 on the second floor. It becomes possible to efficiently use the internal heat for warming the living rooms 21 to 24. At this time, the dining kitchen 12 is used as an atrium space, and the living rooms 21 to 24, which are heat transfer destinations, are provided so as to surround the second-floor atrium portion, so that the heat transfer can be performed on the rising airflow. As a result, it is possible to effectively use heat generated in the building 10 and to improve energy efficiency in the building 10. That is, energy consumption in the building 10 can be reduced, and a building that is economically beneficial and that is favorable from the viewpoint of environmental conservation can be realized.

  Since the living rooms 21 to 24 are provided so as to surround the dining kitchen 12, it is possible to prevent the heat in the dining kitchen 12 from escaping to the outside wastefully, and the heat insulation effect in the dining kitchen 12 can be expected.

  Moreover, as a heat insulation measure, a high heat insulating material was disposed on the wall around the dining kitchen 12 and the roof floor directly above the dining kitchen 12 was used as a roof garden. Thereby, the heat loss in the dining kitchen 12 can be reduced, and the thermal efficiency is further improved.

  Moreover, since it was set as the structure which performs automatic opening-and-closing control about the opening-and-closing members 21c-24c provided in each living room 21-24 of the second floor as an airflow control system which performs the airflow control in the building 10, special operation of a user (resident) The airflow can be generated from the dining kitchen 12 toward the living rooms 21 to 24 without accompanying. Therefore, it is possible for the user to warm up the living rooms 21 to 24 conveniently.

  The dining kitchen 12 may be warmed before or after a meal in winter or the like, but it is considered that the dining kitchen 12 does not need to be kept warm otherwise. Therefore, it can be said that it is practically desirable to warm other rooms using the heat in the dining kitchen 12 as described above.

As conditions for generating an air flow (warm air flow) from the dining kitchen 12 to each of the rooms 21 to 24,
-The indoor temperature T1 of the dining kitchen 12 is higher than the reference temperature REF,
・ There are people in each of the living rooms 21-24 on the second floor.
-The temperature difference (= T1-T2 etc.) between dining kitchen 12 and each living room 21-24 is larger than predetermined value (alpha, beta mentioned above),
When each of these conditions is satisfied, the open / close members 21c to 24c are opened. Thereby, the heat in the dining kitchen 12 can be effectively used for the warm air of each living room 21-24. Moreover, it can suppress that warm air is performed wastefully although there is no person in each living room 21-24.

  Moreover, since it was set as the structure which determines the open condition of the opening-and-closing member 21c-24c individually about each living room 21-24, warming can be performed for every living room, and comfort can be improved for a user (resident | resident).

  If the time zone for warming up each of the living rooms 21 to 24 is determined in advance, it is possible to warm up each of the living rooms 21 to 24 before a person actually moves to each of the living rooms 21 to 24. Become.

(Second Embodiment)
Next, the second embodiment will be described focusing on the differences from the first embodiment.

  In this embodiment, the structure shown in FIG. 7 is employ | adopted regarding the warm air about each room 21-24 of the second floor. FIG. 7 is a plan view showing the floor plan of the second floor portion. FIG. 7 corresponds to the second-floor partial structure of FIG. 2 described above. Here, for convenience of explanation, a structure in which two L-shaped rooms 71 and 72 are provided is illustrated. That is, the dining kitchen 12 has a structure surrounded by two L-shaped living rooms 71 and 72. The room 71 corresponds to the above-described rooms 21 and 22, and the room 72 corresponds to the above-described rooms 23 and 24.
