Example 1
Example 1 demonstrates the example which utilizes the air conditioning system which concerns on this invention in the summer, referring FIG.1 and FIG.4 (b). The air flow can be easily understood by referring to the arrows.

  In summer, when the temperature of the living environment unit 10 exceeds 23 ° C., the temperature sensor 42 senses the control device 43 so that the main fan 12, the sub fan 22, the electromagnetic valve 13, the second electromagnetic valve 23, and the top floor electromagnetic The valve 2a3, the circulator 111a, the shielding plate 301a, and the exhaust heat fan 302 are instructed whether or not to operate. Specifically, the main fan 12 is operated in the forward rotation direction, the sub fan 22 and the exhaust heat fan 302 are operated, and the circulator 111a is not operated. Further, the skylight 301 is shielded without operating the shielding plate 301a, and the solenoid valve 13 is operated to close. The second solenoid valve 23 and the top floor solenoid valve 2a3 are opened without being operated.

  If it does so, in the building A, the skylight 301 will be shielded by the shielding board 301a, and the air heated by the heat exhaust fan 302 in the hut back part 30 will be discharged | emitted outside. At the same time, air that is maintained at a constant temperature by the geothermal heat GH in the lower floor 20 and is relatively cooler than the living environment unit 10 and is conditioned (dehumidified) by the humidity control material 3 is purified through the main duct 1. While being cleaned by the machine 14, the main fan 12 flows toward the cabin back 30. Further, the solenoid valve 13 is closed, the second solenoid valve 23 and the top floor solenoid valve 2a3 are opened, and the sub fan 22 is operated, so that the air in the lower floor 20 passes through the sub duct 2 and the top floor duct 2a. It is sent to the room 101. The sent air returns to the lower floor 20 through the louver 101a and circulates. As a result of repeating this air circulation, in summer, the temperature of the living environment part 10 is lowered to near the geothermal temperature by the air cooled by the large area ground surface of the lower floor 20.

(Example 2)
Example 2 demonstrates the example which utilizes the air conditioning system which concerns on this invention in winter, referring FIG.2 and FIG.4 (b). Air flow is easy to understand by referring to the arrows.

  In winter, when the temperature of the living environment unit 10 falls below 15 ° C., the temperature sensor 42 senses, so that the control device 43 operates the main fan 12 in the reverse rotation direction, operates the circulator 111a, the sub fan 22 and The exhaust heat fan 302 is not operated and the electromagnetic valve 13 is not operated, and the second electromagnetic valve 23 and the uppermost electromagnetic valve 2a3 are operated and closed. In addition, the shielding plate 301 a is operated to open the skylight 301 so that sunlight is poured into the shed 30.

  Then, inside the building A, the air heated by the sunlight from the skylight 301 is not exhausted from the hut back 30 by the exhaust heat fan 302, and the electromagnetic valve 13 is opened. 2 The solenoid valve 23 and the top floor solenoid valve 2a3 are closed and the sub fan 22 is stopped, so that the main fan 12 flows toward the lower floor 20 while being cleaned by the air cleaner 14 through the main duct 1, It is kept at a constant temperature by the geothermal heat GH of the lower floor 20 and is relatively cooler than the living environment part 10, and becomes warm air mixed with the air conditioned (humidified) by the humidity control material 3. This warmed air rises to the room 101 through the louver 101a, diffuses by the circulator 111a in the blow-off part 111, and returns to the shed 30 through the uppermost room 101 to circulate. As a result of the repeated air circulation, in the winter season, the temperature of the living environment part 10 rises above the geothermal temperature due to the air heated by the geothermal heat and sunlight of the large area.

(Example 3)
In Example 3, an example in which the air-conditioning system according to the present invention is used in spring and autumn will be described with reference to FIGS. 3 and 4B. Air flow is easy to understand by referring to the arrows.

  In spring and autumn, when the temperature sensor 42 senses the temperature in the range of about 15 ° C. to 23 ° C. of the living environment unit 10, the control device 43 operates the main fan 12 in the reverse rotation direction and operates the exhaust heat fan 302. The circulator 111a and the sub fan 22 are not operated. The skylight 301 is shielded without actuating the shielding plate 301a, the solenoid valve 13 and the second solenoid valve 23 are actuated to be closed, and the uppermost solenoid valve 2a3 is opened without being actuated.

  Then, while the skylight 301 is still shielded by the shielding plate 301a inside the building A, the air that is unnecessarily warmed by the exhaust heat fan 302 is discharged to the outside, and the top floor duct 2a is discharged through the gallery 101a. The air rising inside is closed by the air cleaner 14 through the main duct 1 because the solenoid valve 13 and the second solenoid valve are closed, the top floor solenoid valve 2a3 is opened, and the sub fan 22 is stopped. On the other hand, the flow is directed toward the lower floor 20 by the main fan 12, and is maintained at a constant temperature by the geothermal GH of the lower floor 20, and is mixed with the air that has been conditioned (dehumidified or humidified) by the humidity control material 3. It becomes air. This air rises to each room 101a through the louver 101 and circulates back to the top floor duct 2a. As a result of the repetition of this air circulation, the living environment section 10 is filled with air that is cleaned by the air purifier 14 and of appropriate humidity in spring and autumn.

  Therefore, the air conditioning system according to the present invention can realize a comfortable indoor space throughout the seasons. Since it is applied to a wooden, reinforced concrete, or steel-framed building A by the joist-less construction method in which the lower floor 20 and the inside of the wall W and the shed 30 are not continuous spaces, the air flow in the living environment section 10 is further improved. It can be precisely controlled, and the desired temperature can be freely adjusted and comfortable humidity can be achieved. Since it is constructed without taking in outside air, air temperature control and humidity control can be performed more efficiently. In addition, it is configured to be automatically controlled by the control means 4 and maintained at a constant temperature by the geothermal GH in the lower floor 20 and air-conditioned by the humidity control material 3 to be sent to the room for air conditioning. Because comfortable air conditioning is realized only by off work, it is very easy for the user to handle. Since geothermal GH obtained from the large surface of the floor 20 is utilized, expensive equipment such as a heat exchanger is not required.

  Here, in the present invention, the humidity control material 3, the air cleaner 14, the main duct 1, the sub duct 2, the electromagnetic valve 13, the second electromagnetic valve 23, the main fan 12, the sub fan 22, the circulator 111a, the skylight 301, and the shielding thereof. Various components such as the plate 301a and the exhaust heat fan 302 are achieved by known means. In the present invention, in particular, the geothermal GH is sufficiently utilized, and these are appropriately controlled and interlocked every four seasons, so that the heat exchanger ( Air conditioning system or air conditioning method that can provide a comfortable indoor space at a low cost is unnecessary. In the above embodiment, for the sake of convenience, the air cleaner and the control device are controlled by one electric system, but two systems, that is, whether the control device and the air cleaner are to be operated separately, are different. You may make it control by a system | strain. In addition, regarding the main fan, an example of a configuration having a single blade that can create both an upward flow and a downward flow of air has been illustrated, but the configuration of two blades has an upward or downward flow of air. The flow may be created with separate vanes.

  As mentioned above, although one Embodiment of this invention was illustrated and explained in full detail, this invention is not limited to the said embodiment. The present invention can be modified in various ways without departing from the scope of the claims.
