A heating device 5 is arranged in the first underfloor space 21 and heated air is introduced to other underfloor spaces 22 to 27 depending on opening/closing states of first to ninth dampers 4A to 4I. The heated air is also introduced to indoor spaces through first to third floor blowout ports 11H to 13H. First to sixth exhaust fans 3A to 3F are arranged at appropriate positions on outer wall members so as to continuously ventilate the indoor spaces. Thus, an air ventilation route is constructed so that the fresh air taken in through the underfloor inlet 20H is circulated from the first underfloor space 21 to all or a portion of the other underfloor spaces 22 to 27, introduced to the indoor spaces mainly through the first to third floor blowout ports 11H to 13H and discharged to an outside through the first to sixth exhaust fans 3A to 3F.

Description

  The present invention relates to an underfloor heating house in which an underfloor heating function is added to a house having a constant ventilation facility, and an underfloor heating system applied thereto.

  Conventionally, air conditioning equipment for indoor spaces in houses and ventilation equipment for indoor spaces are generally handled as separate equipment. For example, the problem of how to heat an indoor space with an underfloor heating device as an air conditioner and the problem of how to ventilate an indoor space with a ventilating fan or the like are treated as separate problems. It has been done when needed.

  By the way, the revision of the Building Standards Act in July 2003 has made it mandatory to install a regular ventilation facility that ventilates indoor spaces for 24 hours in a house. However, as described above, the air conditioning system and the ventilation system are not linked. As a result, for example, in winter, residents dislike the entry of cold outside air into the indoor space and always shut down the ventilation function by forcibly stopping the ventilation equipment. Various usage modes are allowed. Such a usage mode causes a problem that indoor polluted air is not discharged to the outside.

  On the other hand, in Patent Document 1, a hot air duct is installed under the floor, and hot air is blown out from the hot air duct into the underfloor space and the indoor space, and the floor heating is provided with an exhaust duct for exhausting the indoor space. An apparatus is disclosed. It can be said that this device is a facility in which air conditioning and ventilation are linked. However, in the apparatus of Patent Document 1, since the arrangement of the hot air duct and the exhaust duct is indispensable, the equipment has to be large. Moreover, it is an apparatus configuration that is difficult to apply unless the indoor space to be heated is fixed, and there is a problem that it is difficult to flexibly set the heating area according to the usage mode of the indoor space.

  According to this configuration, the vent hole is opened or closed by the opening / closing device, whereby the underfloor space communicated with each other and the underfloor space blocked can be partitioned. Therefore, based on the selection operation given to the operation unit, the pattern data in the storage unit can be read and the heating operation pattern (heating area) can be freely set. In addition, since an exhaust route passing through a predetermined underfloor air inlet, vent, floor outlet, and exhaust port is set according to the heating area, it is possible to always support ventilation. And since the outside air is once taken into the underfloor space from the underfloor air intake and is heated by the heating equipment and then introduced into the indoor space from the floor outlet, the cold air does not directly enter the indoor space, There is no discomfort to residents.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a plan view showing a floor plan of an indoor space 1A of an underfloor heating house 1 to which the present invention is applied, and FIG. 2 shows a section of the underfloor space 1B corresponding to the floor space of the indoor space 1A of the underfloor heating house 1. FIG.

  In this embodiment, as shown in FIG. 1, as an indoor space 1A, a dining room 11, a living room 12, a bedroom 13, a hall 14, a hallway 15 (including a toilet), a kitchen 16, and a washroom (including a bathroom) The example provided with 17 is shown. The indoor space 1A represents the first floor portion of a two-story dwelling unit. The outer periphery of these indoor spaces is partitioned by an outer wall member (wall member that partitions the indoor space from the outside) 101. Moreover, each indoor space is divided by an inner wall member, a door, etc. except the dining room 11, the living room 12, and the kitchen 16 which comprise LDK.

  A plurality of exhaust ports for exhausting the air in the indoor space 1A to the outside are perforated at appropriate positions on the outer wall member 101. The first to sixth ventilation fans 3A to 3F are respectively assembled to these exhaust ports, and the air in each indoor space is forcibly exhausted to the outside by driving these ventilation fans 3A to 3F. Specifically, the first ventilation fan 3A corresponding to the dining room 11 and the living room 12, the second ventilation fan 3B corresponding to the bedroom 13, the third ventilation fan 3C corresponding to the kitchen 16, and the bathroom (bathroom) ), Fourth and fifth ventilation fans 3D and 3E are arranged corresponding to 17, and a sixth ventilation fan 3F is arranged corresponding to the corridor (toilet) 15. These first to sixth ventilation fans 3A to 3F are equipment for continuous ventilation, and are all ventilation fans that are operated continuously for 24 hours.

  The floor member 102 constituting the floor surface of the dining room 11 and the living room 12 has a first floor outlet 11H for taking warm air (air) from the underfloor space 1B (the first underfloor space 21 and the second underfloor space 22). And the 2nd floor outlet 12H is provided. In addition, the floor member 103 constituting the floor surface of the bedroom 13 is also provided with a third floor outlet 13H for taking in warm air from the underfloor space 1B (third underfloor space 23).

  As shown in FIG. 2, a plurality of underfloor spaces 1B are partitioned corresponding to such an indoor space 1A. The underfloor space 1B corresponds to the first underfloor space 21 corresponding to the dining room 11, the second underfloor space 22 corresponding to the living room 12, the third underfloor space 23 corresponding to the bedroom 13, and the hall 14. A fourth underfloor space 24, a fifth underfloor space 25 corresponding to the hallway 15, a sixth underfloor space 26 corresponding to the kitchen 16, and a seventh underfloor space 27 corresponding to the washroom 27 are included.

  The outer periphery of these underfloor spaces is partitioned from the outside by an outer peripheral base material 201 (an outer peripheral wall that partitions the underfloor space and the outside). Moreover, each underfloor space 21-27 is divided by the inner side base material 202 (the underfloor wall which partitions off several underfloor space). The outer peripheral base material 201 and the inner base material 202 are formed of basic concrete having a predetermined width and height. The foundation structure of the underfloor heating house 1 is formed by the foundation concrete and the soil concrete constituting the bottom surfaces of the underfloor spaces 21 to 27. Here, it is desirable to apply a heat insulating material around the outer periphery base material 201 to insulate the underfloor space 1B. In FIG. 2, the positions of the first to sixth ventilation fans 3A to 3F and the first to third floor outlets 11H to 13H are added for convenience of explanation, but these are on the outer peripheral base material 201 or It does not necessarily exist in the first to third underfloor spaces 21 to 23.

  An underfloor inlet 20H for taking outside air into the underfloor space 1B is provided in a portion of the outer peripheral base material 201 that divides the first underfloor space 21 (the underfloor inlet 20H is also added for convenience in FIG. 1). ing). The outside air taken in from the underfloor intake port 20H can be circulated in part or in whole from the first underfloor space 21 to the other underfloor spaces 22 to 27. And it is introduced into the indoor space 1A (especially the dining room 11, living room 12, and bedroom 13) through the first to third floor outlets 11H to 13H, and further to the other indoor spaces through a gap under the door. Is also introduced, and an air ventilation route is formed in which the air flows out to the outside through part or all of the first to sixth ventilation fans 3A to 3F. The airflow along the ventilation route is generated by the suction force generated by the operation of the first to sixth ventilation fans 3A to 3F.

  Each of the inner base materials 202 that partition the underfloor spaces is provided with nine vents for circulating air between the underfloor spaces. These vents are assembled with first to ninth dampers 4A to 4I (opening / closing devices) that open or close the vents. Each of the dampers 4A to 4I is provided with an unillustrated opening / closing drive device, and switching between the open state and the closed state is remotely controlled. When the dampers 4A to 4I are in the open state, the adjacent underfloor spaces are in communication with each other, and air can flow. On the other hand, when the dampers 4A to 4I are in the closed state, the adjacent underfloor spaces are blocked, and the air flow is substantially disabled. Therefore, it is possible to freely control the air flow in the underfloor space by opening any one of the first to ninth dampers 4A to 4I and closing the rest.

  On the soil concrete in the first underfloor space 21, a hot air blowing type heating device 5 is arranged. The heating device 5 includes a heat pump air conditioner (HP) 51 that generates warm air and a heat storage unit 52 that stores heat generated by the heat pump air conditioner 51. The heat pump air conditioner 51 is provided with an outdoor unit (not shown). The warm air generated by the heat pump air conditioner 51 is guided to the heat storage unit 52 through the duct 51A (see FIGS. 3 and 4).

  3 is a cross-sectional view of the heat storage unit 52 in a top view, and FIG. 4 is a cross-sectional view in a side view. The heat storage unit 52 includes a plurality of thin heat storage plates 54, 54, 54... Made of a latent heat storage body in a housing 53.

  The casing 53 is a casing having a rectangular tube shape with a rectangular cross section, with its inlet side 52T and outlet side 52E opened. A chamber 55 connected to the outlet side of a duct 51A into which hot air generated by the heat pump air conditioner 51 is sent is closely attached to the inlet side 52T. Accordingly, the warm air from the heat pump air conditioner 51 is introduced into the inlet side 52T of the housing 53 without leakage through the space 55H in the chamber 55.

As the heat storage plate 54, for example, a plate prepared by enclosing a latent heat storage material such as normal paraffin in a plastic resin flat container can be used. Examples of physical properties of the latent heat storage body that can be suitably used in the present embodiment include a phase change temperature = 36 ° C., a heat of fusion of 175 kJ / kg, a density = 900 kg / m ³ , a specific heat = 2500 J / kgK, and a thermal conductivity = 0. 219 W / mk, working volume = 0.68 m ³ .

  A plurality of such heat storage plates 54 are arranged in parallel on the same plane as shown in FIG. 3, and as shown in FIG. Are stacked. Note that a rack (not shown) is assembled in the housing 53 in order to allow such heat storage plates 54 to be arranged in parallel or in multiple layers.

  Since the heat storage unit 52 has such an internal configuration, when the hot air from the heat pump air conditioner 51 is introduced into the housing 52 from the inlet side 52T, the hot air passes through the ventilation path 53H. The heat of the warm air is given to each heat storage plate 54, and the heat storage plate 54 stores heat. And the warm air after heat exchange blows off from the exit side 52E of the housing | casing 52 to the 1st underfloor space 21, and is provided for heating. In addition, in the part corresponding to the exit side 52E on the soil concrete of the 1st underfloor space 21, in order to suppress the heat outflow into the soil, it is desirable to lay a heat insulating material or the like.

  On the other hand, once each heat storage plate 54 is stored, if normal temperature air is introduced from the inlet side 52T into the housing 52 without supplying warm air from the duct 51A, the normal temperature air passes through the ventilation path 53H. Then, the heat storage plate 54 is heated by the heat radiated, and hot air can be blown out from the outlet side 52E. That is, after the heat storage of the heat storage plate 54 is completed, the heat pump air conditioner 51 does not need to perform an operation of generating heat, and only needs to perform a blowing operation with a blower fan or the like. Therefore, energy saving can be achieved.

  The warm air blown into the first underfloor space 21 from the heating device 5 is introduced into the other underfloor spaces 22 to 27 by opening the dampers 4A to 4I. The underfloor spaces 21 to 27 into which the warm air is introduced are heated, and the corresponding indoor spaces 11 to 17 are heated by radiant heat passing through the floor member. Further, the warm air is introduced into the indoor space through the first to third floor outlets 11H to 13H, and the indoor space is directly heated by the warm air. In this embodiment, the dining room 11, the living room 12, and the bedroom 13 (hereinafter referred to as the first indoor space) having the first to third floor outlets 11H to 13H are connected to the first to third floor outlets 11H to 13H. Heating is performed by both the supplied warm air and the radiant heat. On the other hand, the hall 14, the corridor 15, the kitchen 16, and the washroom 17 (above, the second indoor space) that do not have a floor outlet are exclusively heated by the radiant heat.

  Then, based on FIG. 5, the underfloor heating system 1C applied to the underfloor heating house 1 of this embodiment is demonstrated. The underfloor heating system 1C includes a control unit 60 that controls these operations, and an operation unit 70 that receives an operation instruction from a user, in addition to the heat pump air conditioner 51 and the first to ninth dampers 4A to 4I. . The control unit 60 includes an HP (heat pump) control unit 61, a damper opening / closing control unit 62 (control means), a pattern storage unit 63 (storage unit), and a pattern setting unit 64.

  The HP control unit 61 controls the operation of the heat pump air conditioner 51. For example, when an operation instruction is given from the operation unit 70, the HP control unit 61 activates the heat pump air conditioner 51 and releases warm air into the first underfloor space 21. And in the state where the heat storage to the heat storage plate 54 is completed, the heat generation in the heat pump air conditioner 51 is stopped, and only the blower fan is driven to execute the energy saving operation. It is a preferable control mode of the HP control unit 61 that heat is generated by the heat pump air conditioner 51 in the late-night power time period, the heat is stored in the heating and heat storage plate 54, and the heating is performed by heat radiation from the heat storage plate 54 in the daytime. is there.

  The damper opening / closing control unit 62 gives a control signal to an unillustrated opening / closing drive device attached to the first to ninth dampers 4A to 4I, and controls their opening / closing operations. That is, the damper opening / closing control unit 62 sets some of the first to ninth dampers 4A to 4I to “open state” and the rest to “closed state” based on a predetermined heating operation pattern, A part or all of the indoor space 1A is in a heating state.

  For example, when the operation pattern of all-room heating is selected by the operation unit 70, the damper opening / closing control unit 62 opens all of the first to ninth dampers 4A to 4I. In this case, the warm air generated from the heating device 5 reaches all the underfloor spaces 21 to 27, and all of the dining room 11, living room 12, bedroom 13, hall 14, hallway 15, kitchen 16 and washroom 17 are heated. It becomes a state.

  In addition, when the LD heating operation pattern for heating the dining room 11 and the living room 12 is selected by the operation unit 70, the damper opening / closing control unit 62 opens the first damper 4A while the second, The sixth and eighth dampers 4B, 4F, 4H are closed. Thereby, the 1st, 2nd underfloor space 21 and 22 corresponding to the dining room 11 and the living room 12 turns into the closed space interrupted | blocked with the other underfloor space, and both rooms will be in the state heated. The remaining dampers 4C, 4D, 4E, 4G, and 4I may be in an open state or a closed state.

  The ventilation route is automatically set by driving the first to sixth ventilation fans 3A to 3F and the opening / closing control of the first to ninth dampers 4A to 4I as described above. In the case of the above-described all-room heating operation pattern, a ventilation route of underfloor intake port 20H → first to third floor outlets 11H to 13H → first to sixth ventilation fans 3A to 3F is formed. On the other hand, in the case of the above-described LD heating operation pattern, the ventilation route is such that the underfloor inlet 20H → first and second floor outlets 11H, 12H → first to sixth ventilation fans 3A to 3F. According to the present embodiment, since the ventilation route is formed by driving the first to sixth ventilation fans 3A to 3F, air supply means such as a fan is provided at the arrangement position of the first to ninth dampers 4A to 4I. There is an advantage that it is not necessary to install.

  The pattern storage unit 63 stores a plurality of heating operation patterns determined according to the arrangement of the indoor space to be heated, that is, the opening / closing patterns of the first to ninth dampers 4A to 4I. For example, in addition to the above-described all-room heating and LD heating, warm air can be introduced into the under-floor spaces according to heating operation patterns such as heating centering on the bedroom 13 and heating centering on the washroom 17 and LDK. A plurality of patterns are stored in the pattern storage unit 63 in advance. The damper opening / closing control unit 62 reads the information in the pattern storage unit 63 and controls to open / close the first to ninth dampers 4A to 4I when an instruction to select a specific heating operation pattern is given from the operation unit 70. .

  When the heating operation pattern is changed from the specific first pattern to a second pattern different from the specific first pattern, the pattern setting unit 64 sets the underfloor space corresponding to the indoor space that is the heating target in the first pattern. The opening / closing patterns of the first to ninth dampers 4A to 4I are set so that warm air is delivered to the underfloor space that is not subject to heating in the first pattern and is subject to heating in the second pattern. A specific example of this point will be described later with reference to FIGS.

  The operation unit 70 includes, for example, a remote control device provided with operation buttons, a liquid crystal touch panel, and the like, and receives various user operation instructions for the underfloor heating system 1C. As described above, a heating operation pattern selection instruction is also accepted by the operation unit 70.

  Hereinafter, a specific example of the heating operation pattern will be described with reference to the drawings. 6A is a plan view showing an example of a heating operation pattern, and is a plan view showing a state in which an LDK-centered heating operation pattern (hereinafter referred to as a first pattern) is being executed, FIG. ) Is a tabular diagram showing the open / closed states of the first to ninth dampers 4A to 4I in the first pattern. In the first pattern, the dining room 11, the living room 12, the hallway 15, and the kitchen 16 are heated.

  When this first pattern is selected by the operation unit 70, the damper opening / closing control unit 62, as shown in FIG. 6B, the second, fourth, seventh, ninth damper 4B, 4D, 4G, 4I. Is closed and the remaining dampers are opened. Thereby, the 1st, 2nd, 5th, 6th underfloor space 21, 22, 25, 26 corresponding to dining room 11, living room 12, hallway 15, and kitchen 16 is blocked from other underfloor spaces It becomes.

  In this state, when the HP control unit 61 operates the heat pump air conditioner 51, warm air is blown into the first underfloor space 21, and the air in the first underfloor space 21 is converted into warm air. This warm air passes through the route of the first damper 4A → the sixth damper 4F → the fifth damper 4E → the eighth damper 4H (or the reverse route) as indicated by an arrow F1 in FIG. The second, fifth, and sixth underfloor spaces 22, 25, and 26 are circulated. As a result, these underfloor spaces are filled with warm air, and the dining room 11, living room 12, corridor 15 and kitchen 16 are heated by radiant heat passing through the floor members. In addition, since warm air is blown out from the first and second floor outlets 11H and 12H, the LDK space is also heated by this warm air. The ventilation route in the first pattern is the route of the underfloor intake port 20H → first and second floor outlets 11H, 12H → first to sixth ventilation fans 3A to 3F.

  FIG. 7A is a plan view showing another example of the heating operation pattern, and is a plan view showing a state in which a heating operation pattern (hereinafter referred to as a second pattern) in which the bedroom 13 is emphasized is being executed. FIG. 7B is a tabular view showing the open / closed states of the first to ninth dampers 4A to 4I in the second pattern. In the second pattern, the dining room 11, the living room 12, and the bedroom 13 are heated.

  When the second pattern is selected by the operation unit 70, the damper opening / closing control unit 62 closes the third, sixth, and eighth dampers 4C, 4F, and 4H, as shown in FIG. Open the remaining dampers. Thereby, the 1st, 2nd, 3rd underfloor space 21, 22, 23 corresponding to the dining room 11, the living room 12, and the bedroom 13 will be in the state interrupted | blocked from the other underfloor space. Accordingly, the warm air in the first underfloor space 21 passes through the route of the first damper 4A → the second damper 4B, as indicated by the arrow F2 in FIG. , 23. Thereby, the dining room 11, the living room 12, and the bedroom 13 are heated by the radiant heat which let the floor member pass, and the 1st-3rd floor blowing outlets 11H-13H. The ventilation route in the first pattern is the route of the underfloor inlet 20H → first to third floor outlets 11H to 13H → first to sixth ventilation fans 3A to 3F.

  When the heating operation pattern is changed from the first pattern to the second pattern, the warm air in the second underfloor space 22 below the living room 12 that is the heating target in the first pattern is the heating target in the first pattern. Instead, the second pattern is delivered to the third underfloor space 23 of the bedroom 13 that is to be heated. That is, the warm air in the second underfloor space 22 generated during the heating operation in the immediately preceding first pattern is introduced into the third underfloor space 23 that is not yet filled with warm air. For this reason, the temperature rising efficiency of the third underfloor space 23 can be increased. The pattern setting unit 64 sets the opening / closing pattern of the first to ninth dampers 4A to 4I so that the warm air is transferred between the adjacent underfloor spaces.

  That is, the pattern storage unit 63 stores a plurality of opening / closing patterns in accordance with the indoor space to be heated. For example, when the bedroom 13 is to be heated, warm air can be introduced into the corresponding third underfloor space 23 by a plurality of routes, and the opening / closing patterns of the first to ninth dampers 4A to 4I according to each route. Is remembered. When the heating operation pattern is changed, the pattern setting unit 64 generates an underfloor space generated during the heating operation in the immediately preceding heating operation pattern from among the plurality of opening / closing patterns stored in the pattern storage unit 63. The open / close pattern is selected so that the warm air is introduced into another underfloor space not yet filled with warm air. Thereby, a heating system with little energy loss is realized.

  According to the underfloor heating house 1 of the present embodiment, the first to ninth dampers 4A to 4I are opened or closed to partition the underfloor space that is in communication with the underfloor space that is blocked from each other. Therefore, the heating operation pattern (heating area) can be set freely. In addition, since an exhaust route passing through the underfloor air inlet 20H, the vents (dampers 4A to 4I), the floor outlets 11H to 13H, and the exhaust ports (ventilators 3A to 3F) is set according to the heating area, it is always ventilated. It can correspond to. And since outside air is once taken in into the underfloor space 1B from the underfloor air inlet 20H and heated by the heating device 5, it is introduced into the indoor space 1A from the floor outlets 11H to 13H.
