FIGS. 1-7 shows 1st Embodiment of the air-conditioning system concerning this invention, The schematic diagram which shows the whole structure at the time of FIG. 1 applying to a 2 * 4 house (or conventional wooden frame house), 2 is a plan view of the basic part, FIG. 3 is a schematic configuration diagram enlarging part A of FIG. 1, FIG. 4 is an explanatory view showing a modified example of the installation state of the dehumidifier, and FIGS. FIG. 7 is a schematic diagram showing the overall configuration when applied to a steel frame / RC house.

  In FIG. 1, the air conditioning system of the house 1 includes an outer wall air passage 3 as a geothermal energy layer on each side of the east, west, south, and north formed inside the outer wall 2 and a vertical state inside the inner wall or under the floor on the first or second floor. Indoor air passages 4a to 4c formed in a horizontal state, a ceiling air passage 5 as a ceiling lining thermal energy layer formed on the back of the ceiling of the second floor, an upper end opening to the ceiling air passage 5, and a lower end of the floor below the first floor And a connection air passage 6 in a substantially vertical state communicating with a heat storage chamber 7 provided in the heat storage chamber 7.

  The upper part of the connection air passage 6 is provided with, for example, a fan 8a capable of forward and reverse rotation, and the underfloor air passage 4b is a connection passage formed by disposing a shielding plate on the lower surface of the floor plate via a joist. (Both not shown) communicate with the upper part of the heat storage chamber 7. The outer wall air passage 3 formed inside the outer wall 2 is formed inside the outer wall heat insulating material 9 disposed on the outer surface side of the outer wall 2, thereby simplifying the configuration of the outer wall 2. It has been. A ceiling heat insulating material 21 is disposed on the back side of the ceiling air passage 5.

  As shown in FIG. 2, the heat storage chamber 7 is shielded from the outside air passage 12 formed in the surrounding area by being partitioned by a base 10 having a rectangular shape in plan view at a substantially central portion below the floor on the first floor. The heat storage chamber heat insulating material 11 (see FIG. 1) is disposed on the inner surface side of the foundation 10. The foundation 10 and the heat storage chamber heat insulating material 11 shield (block) the air flow between the heat storage chamber 7 and the outside air passage 12 so that the heat of the heat storage chamber 7 does not leak to the outside.

  The outdoor air passage 12 is formed between the foundation 10 and the outer wall foundation 13 provided at the position of the outer wall 2 of the house, and by providing a plurality of floor vents 14 at predetermined positions of the outer wall foundation 13, Outside air is introduced into the outside air passage 12 through the underfloor ventilation port 14 so that the underfloor is ventilated. An underfloor heat insulating material 15 (see FIG. 1) is disposed on the lower surface of the indoor air passage 4b that is in contact with the outside air passage 12.

  As shown in FIG. 1, a plurality of heat exchange pipes 16 are buried in the heat storage chamber 7, and one end opening of each heat exchange pipe 16 is connected to the concentration box 17. In addition, a dehumidification box 18 provided with a dehumidifier 19 and a filter 20 is connected to the concentration box 17. That is, the dehumidifier 19 is provided with a compressor 23, a condenser 24, an evaporator 25, a blower fan 26, a drain pan 27, a tank 28, a control circuit 29, and the like in a housing 22 as shown in FIG. 3, for example. The housing 22 is installed in the dehumidifying box 18.

  In the dehumidifier 19, high-temperature and high-pressure refrigerant gas is sent to the condenser 24 by the compressor 23, and the suction air sucked from the suction port 31 is cooled by the condenser 24 by the blower fan 26 that rotates by the operation of the motor 30. Then, the liquid is mixed in a high-temperature and high-pressure gas-liquid mixture and passes through a cavities tube (not shown), thereby entering the evaporator 25 as a low-temperature and low-pressure refrigerant liquid. The refrigerant liquid in the evaporator 25 evaporates by heat exchange with the intake air, and is returned to the compressor 23 as a low-pressure refrigerant gas.

  At this time, the intake air is simultaneously cooled by the evaporator 25 to condense to generate drain water, and this drain water is stored in the tank 28 through the drain pan 27. A predetermined amount of drain water stored in the tank 28 is automatically drained to the outside of the outer wall 2 through a drain pipe 33 as a drain channel connected to the tank 28. Further, the intake air dehumidified and cooled by passing through the evaporator 25 is heated by passing through the condenser 24, and is discharged from the outlet 32 by the blower fan 26 as dehumidified dry air. That is, in the case of the dehumidifier 19, the humidity of the suction air sucked from the suction port 31 is dehumidified by the refrigeration cycle using the refrigerant gas and blown out from the blower outlet 32.

  The dehumidifier 19 is not limited to the dehumidifier 19 using such a refrigeration cycle. For example, the dehumidifier 19 includes a rotary moisture absorption rotor such as a honeycomb rotor (not shown), and a condensation type equipped with a heat exchanger and a small heater. The dehumidifier 19 may be used, or a dehumidifier having another appropriate structure can be used. In particular, when the condensation-type dehumidifier 19 is used, a refrigerant gas such as an alternative chlorofluorocarbon is not required, and the dehumidifier 19 can be used as an environment-friendly dehumidifier. The dehumidifier 19 is installed in the dehumidifying box 18 at a position where maintenance and inspection can be performed as easily as possible from an inspection port (not shown) provided on the floor of the house 1.

  And the blower outlet 18a to which the lower end of the said connection air path 6 is connected is provided in the upper surface predetermined position of the dehumidification box 18 in which the dehumidifier 19 comprised in this way is installed, The said blower outlet 18a is provided with the said The filter 20 is detachably mounted. As this filter 20, for example, an antibacterial filter made of a nonwoven fabric kneaded with an antibacterial agent is used, and the growth of germs and generation of wrinkles on the filter 20 is suppressed, and the deodorizing effect is exhibited.

  The filter 20 is not limited to the use of a nonwoven fabric type filter, and a porous plate type filter such as a ceramic having antibacterial, antibacterial and antifungal effects can also be used. Further, the arrangement position is not limited to the air outlet 18a of the dehumidifying box 18, but is provided at the connection port 17a of the concentration box 17 as shown by a two-dot chain line in FIG. Alternatively, it is arranged at an appropriate position where maintenance work such as replacement or cleaning of the filter 20 is easily performed, such as being provided on the dehumidifying box 18 side of the connection air passage 6.

  Further, in the above description, the dehumidifier 19 is installed in the dehumidifying box 18 to dehumidify the air in the dehumidifying box 18. For example, as shown in FIG. For example, in the heat storage chamber 7, the suction port 31 and the air outlet 32 of the dehumidifier 19 are connected to the connection ports 18 b and 18 c of the dehumidification box 18 through appropriate pipes 36 a and 36 b, and the dehumidifier 19 dehumidifies them. A configuration may be adopted in which the air in the box 18 is dehumidified while being sucked and returned to the dehumidifying box 18 again. If it does in this way, dehumidifier 19 can be installed in the desired position where maintenance work inside heat storage room 7 (or heat storage room 7 outside) is easy.

  In FIG. 1, a fire damper 34 is provided at an intermediate position of the connecting air passage 6 to actuate when heat such as a fire is detected by a sensor (not shown) and shuts off the connecting air passage 6. For example, a control box 35 (operation panel) having a season setting switch, a dehumidification switch, and the like (not shown) is attached to the wall surface on the first floor. By operating the control box 35, the fan 8a rotates in a predetermined direction. The dehumidifier 19 is activated.

  The heat exchange pipe 16 is formed, for example, by connecting a stainless steel pipe provided with an annular protrusion (not shown) for promoting heat dissipation and heat absorption effect on the outer peripheral surface in a U shape, etc. The heat exchange pipe 16 absorbs geothermal heat to heat the internal air, or the heat exchange pipe 16 radiates the heat of the internal air to cool the internal air.

  Next, operation | movement of the air conditioning system of the house 1 comprised in this way is demonstrated. First, when the season is summer, when the season setting switch of the control box 35 is set to summer, for example, the fan 8a rotates, for example, in the forward rotation direction, and the air passages 3 to 6 in the house 1 are shown in FIG. Air flow. That is, in the summer, since the outside air temperature is higher than the temperature in the ground, the air in the heat exchange pipe 16 buried in the ground is absorbed by the geothermal heat to become cold air, and this cold air is rotated by the fan 8a. Then, it flows through the heat exchange pipe 16 as shown by the arrow A and is supplied into the concentration box 17 and the dehumidifying box 18 as shown by the arrow B.

  The cold air supplied to the dehumidifying box 18 becomes cold air dehumidified by the dehumidifier 19 when the dehumidifier 19 is in operation by operating a dehumidifying switch provided in the control box 35, and this is the outlet 18 a of the dehumidifying box 18. While being antibacterial and sterilized by the filter 20 provided in the air, the air is supplied into the connected air passage 6 connected to the air outlet 18a. The cold air supplied into the connection air passage 6 flows into the ceiling air passage 5 from the connection air passage 6 as indicated by an arrow C, and flows through the outer wall air passage 3 and the indoor air passages 4a to 4c as indicated by an arrow D. Thus, the air passes through the air passages 3 to 6 in the house 1 and returns to the heat storage chamber 7 from the connection passage provided at the upper portion of the heat storage chamber 7 so as to communicate with the indoor air passage 4b, that is, dehumidified cold air. Circulates (circulates) through the air passages 3 to 6 of the house 1. Through the circulation of this cold air, the ceiling, floor surface, outer wall 2 and inner wall of the house 1 are cooled, and the room temperature in the house 1 is adjusted by the radiant heat of the cold air, and a desired cooling effect (air condition) is obtained in the house 1. Will be.

  And in the case of this summer, since the heat storage chamber 7 provided under the floor on the first floor is thermally shut off completely from the outside air passage 12, the temperature in the heat storage chamber 7 is embedded in the heat exchange pipe 16. The temperature is maintained at a low temperature corresponding to the temperature in the ground, and cold air circulates from the heat storage chamber 7 as a base point. In the case of driving in the summer, the air passages 3 to 6 provided in the house 1 are particularly activated by operating the dehumidifier 19 in the rainy season or the early summer season when the outside air and the ground are hot and humid. The cold air flowing in the inside can be dehumidified into low-humidity air, further improving the cooling effect and suppressing the occurrence of condensation and soot in the air passages 3 to 6 that are likely to occur in the season. It will be. Further, the drain water generated by the operation of the dehumidifier 19 is automatically drained out of the house 1 through the drain pipe 33 as shown by the arrow in FIG.

  On the other hand, when the season is winter, when the season setting switch of the control box 35 is set to winter, the fan 8a rotates, for example, in the reverse direction, and the air as shown in FIG. The flow of That is, in the winter season, since the outside air temperature is lower than the temperature in the ground, the air in the heat exchange pipe 16 embedded in the ground is heated by the geothermal heat to become warm air, and in the heat storage chamber 7. The temperature is also blocked from the outside air passage 12 and maintained at a predetermined temperature higher than the outside air.

  When the fan 8a is operated in this state, the air having a relatively low temperature in the air passages 3 to 5 in the house 1 is sucked into the connecting air passage 6 as indicated by the arrow H and descends, and the filter is indicated as indicated by the arrow. After passing through 20, it flows through the dehumidifying box 18 and the concentration box 17 and is supplied into the heat exchange pipe 16. At this time, when the dehumidifier 19 is operating, the air supplied into the dehumidifying box 18 is dehumidified and supplied to the concentration box 17, and when the dehumidifier 19 is not operating, the housing of the dehumidifier 19 is operated. It flows around the body 22 and is supplied to the concentration box 17.

  Then, the air supplied from the concentration box 17 into the heat exchange pipe 16 flows through the heat exchange pipe 16 as indicated by an arrow to be heated by geothermal heat to become warm air, and this warm air is stored in the heat storage chamber 7. Is done. The warm air in the heat storage chamber 7 is supplied to the indoor air passage 4b from the connecting passage provided under the floor, flows in the air passages 3 to 5 as indicated by arrows H, and returns to the air passage 6 again. Warm air circulates (circulates) in the house 1. Due to the circulation of this warm air, the cooled air in the ceiling air passage 5 far from the heat storage chamber 7 is forcibly guided to the heat storage chamber 7 portion under the floor through the connected air passage 6 by the operation of the fan 8a and again by the geothermal heat. While being able to heat, the room temperature in the house 1 is adjusted by the radiant heat of this warm air, and an efficient heating effect (air-conditioning state) is obtained in the house 1.

  By the way, in the above description, the 2 × 4 or conventional wooden frame house 1 has been described. However, the air conditioning system of the first embodiment is also applied to the steel structure or RC structure house 1 shown in FIG. it can. Also in the case of this house 1, an outer wall air passage 3 is provided inside the outer wall 2, a ceiling air passage 5 is provided in a flat attic, and indoor air passages 4a to 4c and a connection air passage 6 are provided. A heat storage chamber 7 in which a heat exchange pipe 16 is embedded in the ground and a concentration box 17 and a dehumidification box 18 are installed is provided under the floor. The flow of the air inside is the same as that of the house 1.

  Thus, in the air conditioning system of the house 1 according to the above embodiment, the air in the heat exchange pipe 16 embedded in the ground of the heat storage chamber 7 under the floor is cooled or heated by geothermal heat to cool or warm air. At the same time, it is possible to circulate the air passages 3 to 6 in the house 1 while dehumidifying the cold air and the warm air with the dehumidifier 19, so that even if the outside air is hot and humid as in the rainy season or early summer, The humidity of the air flowing in the passages 3 to 6 can be maintained as desired, the inside of the house 1 can be efficiently cooled and heated by radiant heat of a predetermined humidity, and the condensation in each air passages 3 to 6 Generation | occurrence | production of a wrinkle etc. is suppressed or prevented, and it becomes possible to aim at the durability and the improvement in the hygiene aspect of the house 1.

  In addition, since a filter 20 capable of antibacterial, sterilization, prevention, and the like is disposed at the air outlet 18a of the dehumidification box 18, air flowing through the air passages 3 to 6 of the house 1 is circulated by the filter 20. It can be cleaned, so that no scum or the like is scattered in the house 1, and the cleanliness in the house 1 can be maintained well and stably over a long period of time.

  Furthermore, since the dehumidifier 19 is installed in the dehumidification box 18 provided in the heat storage chamber 7 under the floor, for example, in the summer, the dehumidifier cools the cold air in the heat storage chamber 7 and reliably enters the connected air passage 6. In addition to being able to circulate, maintenance work such as maintenance and inspection of the dehumidifier 19 and the filter 20 can be easily performed using, for example, an inspection port provided on the floor above the heat storage chamber 7. In particular, since the dehumidifier 19 is connected to the drain pipe 33 for draining the dehumidified water outside the house 1, the water removed by the dehumidifier 19 can be automatically drained to the outside of the house 1 through the drain pipe 33. Thus, the maintenance work of the dehumidifier 19 can be performed more easily.

  Moreover, since the heat storage chamber 7 provided in the substantially center part under the floor is completely shielded from the outside air passage 12 by the foundation 10 and the heat storage chamber heat insulating material 11, the foundation 10 of the house 1 is effectively used as the wall surface of the heat storage chamber 7. In addition, the heat storage chamber 7 can be reliably shielded from the outside air passage 12, and the heat in the heat storage chamber 7 is well stored by the heat storage chamber heat insulating material 11 provided in the foundation 10, and the temperature of the heat storage chamber 7 is kept within a predetermined range. Therefore, the heat storage chamber 7 can be used efficiently. In addition, since the heat storage chamber 7 is provided in a substantially central portion of the house 1 with a predetermined area with an outside air passage 12 around it, for example, when laying a stone or the like in the heat storage chamber 7, the heat storage chamber 7 is installed in the entire area. In comparison with the case, it is possible to reduce the number of stones used, and it is possible to form the heat storage chamber 7 that can satisfy both the cost reduction and the heat storage effect at a low cost.

  Furthermore, since the outer wall 2 is formed by the outer wall heat insulating material 9 and the outer wall air passage 3, for example, the thickness of the outer wall 2 can be reduced as compared with a case where the outer wall 2 is configured in two layers via an expensive carbonized cork. The structure can be simplified, such as being thinned, and the outer wall 2 can be obtained at a low cost by which the predetermined heat insulating effect can be obtained by the outer wall heat insulating material 9. An inexpensive house 1 having an air conditioning system can be obtained.

  Further, since the dehumidifier 19 is installed in the dehumidification box 18 or in the heat storage chamber 7 etc. outside the dehumidification box 18, if the dehumidifier 19 is installed in the dehumidification box 18, the dehumidification box 18 is dehumidified. It is possible to easily cope with this by simply disposing the machine 19, the installation structure of the dehumidifier 19 can be simplified, and if the dehumidifier 19 is installed outside the dehumidifier box 18, the dehumidifier 19 can be installed at a desired position where maintenance work such as maintenance and inspection is easy. At the same time, as the dehumidifier 19, an inexpensive one used for dehumidification in the room of a general household can be used, and the installation cost and running cost of the air conditioning system of the house 1 can be further reduced.

  FIGS. 8 and 9 are schematic views showing the same overall configuration as FIG. 1 showing the second embodiment of the air conditioning system according to the present invention. Hereinafter, the same parts as those in the first embodiment will be described with the same reference numerals. The feature of the house 1 of the second embodiment is that the heat exchange pipe 16, the concentration box 17, the dehumidifying box 18, and the connection air passage 6 are installed outside the house 1 (outdoors). That is, as shown in FIG. 8, a plurality of heat exchange pipes 16 are buried in the ground around the house 1 of a 2 × 4 house (or a conventional wooden frame house), and one of the heat exchange pipes 16 is embedded. A concentration box 17 and a dehumidifying box 18 connected to the opening end are installed outdoors, and a connecting air passage 6 connecting the dehumidifying box 18 and the ceiling air passage 5 is installed outdoors.

  And the other end side of each heat exchange pipe 16 is extended in the direction of the heat storage chamber 7 under the floor in a state where it is placed on the ground under the floor of the house 1, and the other open end is positioned in the heat storage chamber 7. Thereby, the heat-exchanged air in the heat exchange pipe 16 passes through the heat storage chamber 7, the air passages 3 to 5 in the house 1, the connection air passage 6, the dehumidification box 18 including the filter 20, the concentration box 17 and the like. Thus, a desired air conditioning effect is obtained in the house 1.

  Note that the second embodiment can also be applied to a steel-structured or RC-structured house 1 as shown in FIG. 9. In this case, the indoor air passage 6 is formed in the back of the first floor ceiling. By extending the air passage 4c and providing a fan 8b that can be rotated in the same manner as the fan 8a, for example, the air in the indoor air passage 4c is forced into the connection air passage 6 by the operation of the fan 8b. Therefore, the air circulation (circulation) efficiency in each of the air passages 3 to 5 may be increased.

  In the second embodiment, in addition to the same effects as those of the first embodiment, the heat exchange pipe 16, the connection air passage 6, the dehumidification box 18 and the like are installed outdoors. It can be easily applied to the housing 1 such as × 4 structure or conventional wooden frame structure, or the existing steel structure or existing RC structure 1 and the dehumidifier 19 and the filter 20 are installed outdoors. As a result, the maintenance / inspection becomes extremely simple, and the operational effect of greatly improving the workability of the maintenance work can be obtained.

  In each of the above embodiments, the lower end of the connection air passage 6 is always connected to the outlet 18a of the dehumidification box 18 in which the dehumidifier 19 is built, and the dehumidification box 18 is connected to the heat exchange pipe 16. However, the present invention is not limited to this. For example, the connection port 17a of the concentration box 17 is connected to the connection port 17a of the concentration box 17. The dehumidifier 19 is disposed between the lower end of the air passage 6 so that it can be switched and connected by a switching damper (not shown), and the dehumidified air blown from the outlet 32 of the dehumidifier 19 is directly connected to the air passage 6. Or it is good also as a structure supplied in the concentration box 17. FIG.

  Further, in each of the above embodiments, an appropriate member having a heat storage effect such as the above-mentioned granite may be laid on the ground of the heat storage chamber 7, and the operation of the fans 8 a and 8 b provided in the connection air passage 6 is also performed. Not only the operation of the season setting switch of the control box 35 but also, for example, the temperature sensor provided in the predetermined air passages 3 to 6, the timer provided in the control box 35, etc. (both not shown) As a configuration to be turned off, the usability of the air conditioning system may be improved. Furthermore, the overall structure of the house 1, the structure of the air passages 3 to 6, the structure of the heat storage chamber 7 and the like in the above embodiment are also examples, and are appropriately changed without departing from the gist of each invention according to the present invention. can do.
