JP 2003-262347 A

  However, in the conventional example, when heating the large underfloor space 102 in the building H, or when heating the underfloor space 102 for a long time, the hot water stored in the hot water storage tank 101 is insufficient. It was necessary to warm the hot and cold water with electric power, which was uneconomical. In order not to use expensive daytime electric power, the capacity of the hot water storage tank 101 must be increased in order to increase the amount of hot water stored in the hot water storage tank 101. Because of the installation, there is a problem that the temperature control device 103 cannot be installed due to restrictions on the site that a large-capacity hot water storage tank 101 cannot be installed in a house with a small site.

  Further, in the conventional example, there is a heating method in which heat is stored in the soil concrete 104 or the soil floor 104 as shown in FIG. In such a heating method, since the heat capacity of the soil concrete 104 and the soil floor 104 is enormous, intermittent heating such as heating only when heating is desired cannot be performed, and continuous heating is performed for 24 hours. However, in a general house, it is not necessary to continuously heat all the rooms including the toilet and the hallway for 24 hours, and unnecessary heating is performed for the resident.

  Therefore, the present invention takes the above-described problems into consideration, and does not increase the outdoor equipment installation space, is comfortable for the resident without waste, is comfortable under the floor, and uses a temperature control means that can perform economical heating. An object is to provide a temperature control device and an underfloor temperature control building.

Therefore, in the present invention, for the temperature control of the building, as an underfloor temperature control device provided with temperature control means in the underfloor space of the building and the dirt floor,
In a building , an underfloor space and a floor between floors are provided at the bottom of the floor, and the floor between the floors of a room where people stay for a long time is provided at the bottom of the floor of a room where people do not stay for a long time. An underfloor temperature control apparatus comprising temperature adjustment means, wherein the underfloor space is provided, and temperature adjustment means is provided in each of the underfloor space and the soil floor ,

I will provide a. As a result, separate temperature control means are provided for the underfloor space and the interstitial floor provided in the building, respectively, and the underfloor space and the interstitial floor can be separately heated.
And the temperature control means in the underfloor temperature control device,

Consists of a radiator installed in the underfloor space, and a heat radiating pipe provided in the dirt floor,
The heat radiator and the heat radiating pipe are connected to the heat pump device, a hot water storage tank connected to the heat pump device for storing hot water, a circulation pipe for guiding the hot water from the hot water storage tank to the space under the floor, and hot water from the hot water storage tank in the circulation pipe. Each connected to a separate circulation pipe of the heat source device consisting of a circulation pump to circulate,

With this configuration, hot water is circulated by the circulation pump via the heat pump device, the hot water storage tank, and the circulation pipe. In the middle of the circulation, the heat of the hot water is radiated by the radiator in the underfloor space, and similarly, the heat of the hot water is radiated by the radiating pipe provided in the dirt floor and the temperature of the building is adjusted. .
Similarly, the temperature control means

  From the heat storage heater installed in the underfloor space, and the heat storage heater installed in the space provided in a part of the dirt floor,

By configuring, the underfloor space can be temperature-controlled by the installed heat storage heater, and the dirt floor can be adjusted by the heat storage heater installed in the space in a part of the floor, each heat storage heater The temperature of the building is adjusted by heat dissipation from the building.

  Further, in the present invention, as a building capable of adjusting the temperature from under the floor, the under-floor temperature control building provided with each of the under-floor temperature control devices,

By providing the above, the building is provided with the temperature control means in the underfloor space and the soil floor, respectively, and the building can be temperature controlled from under the floor by each temperature control means.

Therefore, according to the present invention, since the temperature control means is provided in the underfloor space and the floor of the building, the room in the upper portion of the underfloor space and the room in the upper portion of the floor of the floor can be adjusted from under the floor like floor heating. Comfortable heating similar to heating is possible.
In addition, the temperature control means installs a radiator in the underfloor space, installs a heat radiating pipe in the floor between floors, and connects to a heat source device to obtain a heat source. The stored heat enables comfortable heating for a long period of time, and in the underfloor space, heat is dissipated by a radiator to enable subtle heating from under the floor. In addition, since the temperature under the floor and the floor between floors can be adjusted independently, rooms that stay for a long time can be actively heated, and rooms that stay only for a relatively short time are much warmer. By heating to a certain extent, it is possible to adjust the temperature separately between the underfloor space, which has a huge heat capacity and is not suitable for intermittent heating, and the underfloor space that does not need to be heated all day long. Can be done.

Furthermore, in the present invention, a regenerator heater is installed in the underfloor space, and the regenerator heater is also installed in a space provided in a part of the interstitial floor so that the underfloor space and the interstitial floor can be heated separately. So, it becomes possible to perform economical heating only when necessary by intermittent heating, and in the underground floor where the heat capacity is enormous, economical heating is also possible by storing heat in the underground floor using cheap energy sources such as midnight electricity. It becomes possible.
Then, in the dirt floor floor Ri Do not allow a comfortable heating over a long period of time by utilizing the heat capacity with heat storage and earthen floor itself by using electric power late at night, and since it is not necessary to the hot water storage tank to a large, outdoor equipment This has the effect of reducing the installation space.

In a device provided with a heat source device, as a temperature control means, a radiator is installed in the underfloor space of the building, and a radiating pipe is buried in the dirt floor of the building.
As a heat source for the temperature control means, a heat pump device is provided, and a hot water storage tank is connected to the heat pump device so as to store the heat obtained by the heat pump device as temperature-controlled hot water. Then, a circulation pipe for guiding the hot water in the hot water storage tank to the underfloor space and circulating it again to the hot water storage tank is installed in the underfloor space of the building. Circulation pipes will also be installed in the dirt floor by a separate route independent of the underfloor space.

  A radiator installed in the underfloor space is connected to the middle of a circulation pipe that circulates through the underfloor space. Similarly, a heat radiating pipe installed in the dirt floor is connected and provided in the middle of a circulation pipe circulating through the dirt floor.

  In the underfloor space, hot water is circulated through a circulation pipe, and heat from the hot water is exchanged by a radiator to dissipate the heat, thereby heating the room under the floor from below the floor. In this case, since the space under the floor is small, the heat capacity is small, so that it heats relatively quickly compared to the dirt floor, so intermittent heating can be performed, and hot water is circulated as needed to heat.

  In the dirt floor, hot water is circulated through a circulation pipe, heat is radiated by a heat radiating pipe installed in the dirt floor, and heat is stored in the dirt floor having a large heat capacity. Then, the room above the dirt floor is heated by the heat stored for a long time.

Moreover, in the thing which provides a thermal storage heater, a thermal storage heater is installed in the under-floor space of a building. Similarly, a regenerative heater is installed in a space provided in a part of the floor of the building. In the underfloor space, heat is stored in the regenerative heater when necessary to dissipate, and the room above the underfloor space is slightly warmed.
In addition, in the dirt floor, heat is stored in a heat storage heater provided in the space of the dirt floor by an economical energy source such as midnight power, and is released to the dirt floor. The floor is stored by the heat of the heat storage heater and heats the room above the floor for a long time.

  Embodiment 1 of the present invention will be described below with reference to the drawings. FIG. 1 is a cross-sectional explanatory view seen from a side surface representing Example 1 of the present invention, and FIG. 2 is a cross-sectional explanatory view seen from the same plane.

  H is a building. As shown in FIGS. 1 and 2, the building H is a typical detached building in this embodiment, and a dirt floor H2 is applied to a part of the underfloor space H1 surrounded by the foundation H3. The dirt floor H2 is provided below the floor of a room where people gather at a room provided in the upper part of the dirt floor H2, and is provided below the floor of the living room or dining room. The underfloor space H1 is usually provided under the floor of a room where a large number of people do not gather, and is provided under the floor of a toilet, a washroom, a guest room, a hallway, and the like.

  In this embodiment, as shown in FIG. 1, the foundation H3 portion of the building H is provided with a heat insulating material H4 on the outer surface of the rising portion H3a. Thus, the building H uses a so-called basic heat insulating structure that performs heat insulation from the outside with the foundation H3. In this embodiment, the heat insulating material H4 is installed only on the outer side of the foundation H3, but the heat insulating material H4 may be installed on both the outer side surface and the inner side surface of the rising portion H3a. Further, in the building H, the room above the floor surface H5 is temperature-controlled from under the floor, so that the heat insulating material H4 is not provided between the under-floor space H1 and the floor surface H5 of the building H.

  Reference numeral 1 denotes an underfloor temperature control device. The underfloor temperature control device 1 includes a temperature control means 10 for heating the underfloor space H1 and the earth floor H2 of the building H, and further, as a heat source device for supplying hot water to the temperature control means 10, a heat pump device 20, a hot water storage tank 30, and a circulation pipe 40. Is provided. Furthermore, a circulation pump 50 is provided for circulating hot water from the hot water storage tank 30 to the hot water storage tank 30 via the circulation pipe 40.

  The heat pump device 20 includes an outdoor unit of the heat pump, and can store hot water heated by the heat pump device 20 by being connected to the hot water storage tank 30 in the hot water storage tank 30. The heat pump device 20 and the hot water storage tank 30 are installed outside the building H.

  A circulation pipe 40 is connected to the hot water storage tank 30. The circulation pipe 40 is an underfloor space circulation pipe 41 that returns from the hot water storage tank 30 to the hot water storage tank 30 again through the underfloor space H1 of the building H, and a hot water storage tank again from the hot water storage tank 30 through the dirt floor H2 of the building H. An intersoil circulation pipe 42 returning to 30 is provided, and the under-floor space circulation pipe 41 and the inter-soil circulation pipe 42 are branched by the hot water header 43 so as to pass through the under-floor space H1 and the inter-soil floor H2, respectively.

  A circulation pump 50 is provided between the hot water header 43 and the hot water storage tank 30. Accordingly, the circulation pump 50 sends the hot water stored in the hot water storage tank 30 so as to be circulated to the hot water storage tank 30 via the underfloor space circulation pipe 41 and the soil circulation pipe 42.

The temperature control means 10 includes a radiator 11 and a heat radiating pipe 12. The radiator 11 is installed in the underfloor space H1 and is connected in the middle of the underfloor space circulation pipe 41 to form a hot water circulation path. When the hot water passes through the radiator 11, heat is exchanged to the underfloor space H1. Is possible.
The radiating pipe 12 is installed in the dirt floor H2 and is connected to the middle of the dirt circulation pipe 42 to form a hot water circulation path. When the hot water passes through the radiating pipe 12, heat is exchanged to the dirt floor H2. Heat dissipation is possible.

Next, the operation of the underfloor temperature control device 1 of this embodiment will be described.
In the underfloor temperature control apparatus 1 of the embodiment configured as described above, the hot water warmed by the heat pump apparatus 20 is stored in the hot water storage tank 30, so that the circulation pump 50 is driven as necessary to create a space under the inner floor. Hot water in the hot water storage tank 30 can be circulated in the underfloor space circulation pipe 41 laid in H1.

When the hot water having a certain temperature in the hot water storage tank 30 passes through the radiator 11 via the underfloor space circulation pipe 41 in the underfloor space H1, heat is exchanged by the radiator 11 to dissipate the thermal energy of the hot water. Then, by heating the underfloor space H1 of the building H and heating the floor surface H5 above the underfloor space H1, the room above the floor surface H5 is heated.
Similarly, in the dirt floor H2, when hot water passes through the heat radiating pipe 12 via the dirt circulation pipe 42, heat is exchanged by the heat radiating pipe 12 to dissipate the heat energy held by the hot water, and the earth floor H2 of the building H is removed. The room above the floor H5 is heated by heating and heating the floor H5 above the dirt floor H2.

  For this reason, since the temperature of the underfloor can be adjusted at any time without being influenced by time, weather, etc. as in the prior art, stable heating performance can be exhibited, and thermal efficiency is good.

  Further, in the room above the floor H5 of the underfloor space H1, since there is no need for a person to stay at all times, it is not necessary to always heat, and a slight amount of heating is sufficient, so that heat is dissipated from the radiator 11 in the underfloor space H1. Heat reaches the floor surface H5 above the underfloor space H1 through the air and heats the floor surface H5. In addition, in the interstitial floor H2, since there are many adults in the room above the interstitial floor H2, the room is always heated, so continuous heating is performed instead of intermittent heating. However, since the thermal capacity of the interstitial floor H2 is large, heat storage is performed. Since the amount is large, heating can be performed for a long time by warming and storing the dirt floor H2 using the heat of hot water heated by inexpensive late-night power.

  Then, as described above, by heating the underfloor space H1 and the interstitial floor H2 through another path of the circulation pipe 40, for example, the heat pump device 20 is operated using midnight power, and the soil is heated with hot water heated by midnight power. Heat is stored in the floor H2, and in the room above the floor H2, the room above the floor H2 can be heated by the heat stored in the floor H2 from night to morning and further in the morning. Do not use much hot water. Thereby, the capacity of the hot water storage tank 30 does not require the capacity to warm the entire room of the building H in the same way, and since it is an operation using midnight power, it can be heated at an inexpensive running cost.

  In addition, there is no need to separately provide other temperature control equipment, and if the heat pump device 20 is also used as a hot water supply device or the like, an increase in equipment cost can be suppressed.

  Further, since the periphery of the foundation H3 of the building H is insulated by the heat insulating material H4, heat does not escape to the outside of the building H, and the underfloor space circulation pipe 41, the soil circulation pipe 42, the circulation pipe 40, and the room above the floor H5 Since no heat insulating material is provided between them, most of the heat radiated from the heat radiator 11 and the heat radiating pipe 12 is guided to the room above the floor surface H5 and dissipated into the room above the floor surface H5. Can be.

  A second embodiment of the present invention will be described below with reference to the drawings. FIG. 3 is a cross-sectional explanatory view as seen from a side surface representing Embodiment 2 of the present invention, and FIG. 4 is a cross-sectional explanatory view as seen from the same plane.

  In the second embodiment, as shown in FIG. 3, the building H is provided with a dirt space H6 in the dirt floor H2. Other configurations of the building H are the same as those in the first embodiment.

Moreover, in Example 2, the temperature control means 10 consists of the thermal storage heater 13. The heat storage heater 13 includes an electric heater and a heat storage block capable of storing heat generated from the electric heater, and gradually radiates the heat stored from the heat storage block to the surroundings. 13 External temperature can be adjusted. And the heat storage heater 13 generates heat by midnight power and stores heat.
And the thermal storage heater 13 is installed in the interstitial space H6 provided in the underfloor space H1 and the interstitial floor H2 of the building H.
Therefore, the heat storage heater 13 provided in the underfloor space H1 can adjust the temperature of the room above the underfloor space H1, and the heat storage heater 13 provided in the interstitial space H6 can adjust the temperature of the room above the interstitial floor H2. is there.

The operation of Example 2 will be described below.
The heat storage heater 13 stores heat using midnight power. Then, heat is gradually released to the surroundings throughout the day. That is, in the heat storage heater 13 installed in the dirt space H6, the gradually released heat is absorbed by the dirt floor H2 around the dirt space H6 and warms the dirt floor H2. The warmed floor H2 heats the upper room via the floor surface H5 above the floor H2. Since the dirt floor H2 has a large heat capacity such as dirt concrete that constitutes the dirt, the heat stored in the dirt floor H2 is gradually transferred to a room such as a living room above the dirt floor H2, which is the same as when the room heated the floor. Comfortable heating is performed and the temperature is adjusted for a long time.

  Moreover, in the thermal storage heater 13 provided in the underfloor space H1, the stored heat is gradually dissipated and absorbed by the underfloor space H1, whereby the underfloor space H1 is heated. And by heating the underfloor space H1, it passes through the floor surface H5 above the underfloor space H1 to rooms such as a washroom, a corridor, and a guest room provided above the underfloor space H1, and a slightly warm heating is performed. Done. Heating by the regenerative heater 13 in the underfloor space H1 has a flow of air in the underfloor space H1 as compared to heating performed in the interstitial space H6 of the interstitial floor H2, so that the living room and the like above the interstitial floor H2 Although it is inferior to the heating of the room, it is enough because it is not a place where people always stay.

  Therefore, even in the second embodiment, it is possible to perform comfortable heating all day using only cheap midnight power, and unlike the first embodiment, since the heat storage heater 13 is used, the heat pump device 20 or the like is used. It can be used without the need for troublesome maintenance.

The present invention can be applied to any building such as a detached building or a condominium type building by providing an underfloor space H1 and a dirt floor in advance when building a new building, and can also be used for a building to be renovated as well as a new building. . In particular, it is effective for a building having a place (room) requiring a comfortable temperature where a person always exists and a place (room) used by a small number of people such as one person temporarily.
The underfloor temperature control device can be used regardless of whether it is a new building or an existing building.
