In FIGS. 7A and 7B, 11 is an underground pipe into which air from the outside is introduced, 12 is a blower fan, and 13 is an outside air intake. The underground pipe 11 is buried in the ground to a depth of several m, for example, 5 m. The underground pipe 11 uses the blower fan 12 to introduce air from the outside into its own interior and circulate it while exchanging heat with the underground heat. The air heat-exchanged in the underground pipe 11 can flow from the underground pipe 11 to the mesh pipe 16 (the outer peripheral portion thereof can be air-flowed) arranged in the underfloor space 15 via the heat exchanger 14 on the ground. Move to a pipe) formed in a mesh structure. In the underfloor space 15, a glycemic heat storage layer formed by filling a large number of glycemic stones (not shown) is formed. The air moves from the outer peripheral portion of the mesh pipe 16 into the glycemic heat storage layer in the underfloor space 15. The air that has passed through the Guri stone heat storage layer is supplied to the inside of the building (each room) from each outlet 17 provided on the floor, the partition wall, or the like.

Further, the underground pipe 11 is composed of a double pipe composed of an inner pipe 21 and an outer pipe 22, as shown in FIG. 7B, for example. In FIG. 7B, the outside air taken in from the outside air outlet 13 (see reference numeral 20a in FIG. 7B) passes through the gap 23 between the inner wall surface of the outer pipe 22 and the outer wall surface of the inner pipe 21.

Sodium hypochlorite in a substantially atomized aqueous solution released into the air from the spray portion 28 in the gap between the outer pipe 21b and the inner pipe 21a. Alternatively, an antibacterial agent component such as hypochlorite or particles containing it may be adsorbed and captured to prevent the component (harmful) from being supplied into the living space of the chicken, for example, a porous material such as activated carbon or zeolite. It is a filter that includes.

In the first embodiment, the signal from the timer 29 is transmitted to the control device 27 at predetermined intervals (or intervals independently set by the user, for example, several minutes). Upon receiving the timer signal, the control device 27 controls the pump 23 and the switching unit 25a to supply the aqueous solution (antibacterial agent liquid) from the antibacterial agent liquid tank 22 for a predetermined time (several minutes or the like), for example. It is sent to the spray unit 28 via the pipes 24 and 25, and the spray unit 28 makes the sent aqueous solution (antibacterial agent liquid) substantially shower-like or substantially atomized based on the control signal from the control device 27. And discharge from the nozzle 28a downward (or diagonally downward) in the figure. As a result, the components of the antibacterial agent solution such as sodium hypochlorite or hypochlorite in the aqueous solution released in the form of substantially atom or the fine particles containing the same are placed between the outer tube 21b and the inner tube 21a. If heat is exchanged with geothermal heat in the gap, the rising virus in the air is inactivated or detoxified, or the bacteria in the air are killed. In this way, air in which the virus or bacterium is inactivated or killed and the above-mentioned components and the like are removed is supplied into the living space of the chicken.

Further, in the first embodiment, the control means 27 controls the switching unit (valve mechanism) 25a to send tap water S to the spray unit 28 based on the signal from the timer 29, and the control means 27 sends the tap water S to the spray unit 28. The tap water S may be generated or discharged from the nozzle 28a into the underground pipe 21 as fine particles or mist atomized in a shower shape by the spray unit 28. Even in this case, the tap water S contains sodium hypochlorite having a concentration of 0.1 mg (0.1 ppm) or more per liter and 1 mg (1 ppm) or 2 mg (2 ppm) or less per liter. Since chlorine is contained, the virus or bacteria in the underground pipe 21 is inactivated or killed by chlorine such as sodium hypochlorite contained in the fine particles or mist of the tap water S. Further, even if the action of chlorine such as sodium hypochlorite is taken, the fine particles or mist of the tap water S float in the underground pipe 21 in the process of drifting in the underground pipe 21. The virus or bacterium is attached to itself, and the virus or bacterium is further lowered, moved, or dropped by its own weight toward the antibacterial agent liquid 22a or tap water S stored in the outer pipe 21c with the virus or bacterium attached. Therefore, as described above, the tap water S is atomized or atomized in a shower shape by the spraying portion 28, and is generated and discharged as fine particles or mist in the underground pipe 21. Viruses or bacteria floating in the pipe 21 are prevented from moving from the underground pipe 21 into the living space of the building.
In the above example, the mist or fine particles made of the tap water S are generated or discharged from the nozzle 28a of the spray portion 28, but in the present invention, only a predetermined amount is predetermined in the bottom portion 21c of the outer pipe 21b. By atomizing the stored tap water S (tap water S stored in place of the liquid 22a) by vibration of an ultrasonic transducer (piezoelectric element or the like) submerged in the tap water S. The mist composed of the tap water S may be generated and discharged into the underground pipe 21.

As described above, in the first embodiment, the spray portion 28 causes the virus or bacteria in the air to adhere to itself in the underground pipe 21 and lower it toward the bottom 21c of the outer pipe 21b. It is a mist or mist-like particle, and "it is necessary that the free residual chlorine concentration of tap water S (sodium hypochlorite or the like is 0.1 mg (0.1 ppm) or more per liter) and per liter. 1 mg (1 ppm) or 2 mg (2 ppm) or less is desirable), or a liquid containing a component having the effect of inactivating or detoxifying the virus or killing or reducing the bacteria (antibacterial agent solution 22a). Is made to generate or release fine particles or mist (mist-like particles) formed by atomization. Therefore, for example, fine particles or mist (mist-like particles) of tap water S generated / released in the underground pipe 21. However, the virus or bacteria floating in the underground pipe 21 adheres to itself, and in that state, descends and falls to the bottom 21c of the outer pipe 21b due to its own weight. The liquid that is the source of the fine particles or mist (mist-like particles) is not the "tap water S", but a liquid containing a component having the effect of inactivating or detoxifying the virus or killing or reducing the bacteria. (Antibacterial agent liquid 22a in FIG. 2) ”(for example, a liquid such as sodium hypochlorite having a residual chlorine concentration of more than 1 mg (1 ppm) or 2 mg (2 ppm) per liter) is the same. Therefore, according to the first embodiment, the virus or bacteria floating in the underground pipe 21 can be moved into the liquid 22a (or tap water S) collected in the bottom 21c of the outer pipe 21b. , The virus or bacteria in the underground pipe 21 can be effectively prevented from moving into the living space of the building.

Further, according to the first embodiment, in the underground pipe different from the living space of the chicken, the air rising while exchanging heat with the underground heat in the gap of the underground pipe is dealt with. An aqueous solution containing a component of the antibacterial agent solution 22a (a component such as sodium hypochlorite or water hypochlorite) is released in a substantially shower-like or substantially atomized form, whereby the virus or bacteria in the air is released. Since the air is supplied to the living space of the chicken after being inactivated, detoxified, or killed, it is possible to prevent the chicken from being damaged by the virus or bacteria in the air. Moreover, in the first embodiment, the antibacterial agent in the air after inactivating, detoxifying, or killing a virus or a bacterium by a component of the antibacterial agent solution (sodium hypochlorite, hypochlorite, etc.). The component of the agent solution 22a or the particles containing the agent solution 22a are adsorbed and captured by the filter 30, and the air after the component of the antibacterial agent solution 22a or the particles containing the agent solution 22a is removed is supplied to the living space of the chicken. Therefore, it is possible to prevent the above-mentioned virus or bacterium from inactivating, detoxifying, killing, or the like from affecting the health of the chicken. As described above, according to the first embodiment, the air that is heat-exchanged with the geothermal heat in the underground pipe 21 and inactivated, detoxified, or killed the virus or bacteria is supplied into the living space of the building. Not only can geothermal heat be used for heating and cooling, but also a healthy building space that can prevent health damage caused by viruses or bacteria can be realized, and the above-mentioned viruses or bacteria can be inactivated. It is also possible to prevent the detoxified or killed components and the like from affecting the health of the chicken. Further, in the first embodiment, the air sent into the inner pipe 21a in the underground pipe 21 with the pressure from the fan descends in the inner pipe 21a by the fan, and then the said. Since the liquid (aqueous solution of antibacterial agent) 22a stored in the bottom 21c of the outer tube 21a collides with pressure, bubbling or waviness occurs on the surface side of the liquid 22a stored in the bottom 21c of the outer tube 21b. As a result, particles and the like atomized with "a liquid containing a component having an action of inactivating or detoxifying a virus in the air or killing or reducing the bacteria in the air" can be obtained extremely efficiently and easily. , In the gap between the outer tube 21b and the inner tube 21a and / or in the inner tube 21a.
