  Further, the floor portion 1a is provided with an exhaust port 6 with a grill and two types of air supply ports 7 and 9.

  Here, the air supply port 7 is connected to the blowout part 32 on the floor of the indoor unit 3 of the air conditioner by a duct 82, and the air supply port 9 communicates directly with the underfloor space 4 without passing through the duct. Yes.

  And between the suction part 31 and the exhaust port 6 of the indoor unit 3 of an air conditioner is also connected by the duct 81.

  Furthermore, the indoor unit 3 of the air conditioner has a built-in control unit 3a that controls the operation of the indoor unit 3 of the air conditioner.

  The floor space 5 is provided with a controller 12 for setting a desired operation pattern.

  Next, the operation pattern of the air conditioning system of an Example is demonstrated.

  First, the pattern at the time of heating operation is demonstrated.

  As an initial setting, a predetermined value (for example, 5 ° C.) for controlling the controller 12 to store heat is input to the controller 12 and set in advance.

  As an example, when you want to comfortably warm the space 5 above the floor, especially the time zone when you wake up the next day (for example, around 7:00 am), enter the scheduled wake-up time (for example, 7:00 am) into the controller 12 and set it. To do.

  In response to this, the control unit 3a acquires predicted temperature data for the next day from the server S via the Internet N.

  First, when the predicted temperature of the next day (for example, the average temperature from 7:00 am to 12:00 am) found from the predicted temperature data of the next day acquired in this way is equal to or lower than a predetermined value (for example, 5 ° C.), the control unit 3 a Control as shown in FIG. 3 is performed.

  At 11:00 pm on the day when the unit price of electricity becomes relatively low as midnight power, the on-off valve 33a is opened, a large amount of warm air is blown out from the underfloor blowing section 33, and heat storage in the underfloor space 4 is started. A small amount of warm air is blown out from the blowing unit 32 on the floor.

  Then, from 5 am to 7 am on the next day, the warm air blowing from the underfloor blowing section 33 is set to a small air volume, and the warm air blowing from the above floor blowing section 32 is set to a large air volume.

  As a result, the floor space 5 is sufficiently warmed and is in a comfortable state around 7 am on the next day after the set scheduled wake-up time.

  Further, after 7 am on the next day, since the heat stored in the underfloor space 4 is transmitted through the floor portion 1a, heating is unnecessary or slightly performed for a while.

  If the predicted temperature of the next day (for example, the average temperature from 7:00 am to 12:00 am) found from the predicted temperature data of the next day acquired in this way exceeds a predetermined value (for example, 5 ° C.), heat storage is not performed and control is performed. The unit 3a only needs to perform control to blow out the warm air of the medium air volume from the floor blowing unit 32 from 5 am to 7 am on the next day.

  Also, underfloor heating during normal times and heating that has immediate effect, the on-off valve 33a of the blowout portion 33 for the underfloor is opened, or the open / close valve 32a of the blowout portion 32 for the floor is opened to warm air from these. Can be performed by blowing out.

  Next, the pattern during the cooling operation will be described.

  As an initial setting, a predetermined value (for example, 30 ° C.) for controlling the controller 3a to store heat is input to the controller 12 and set in advance.

  As an example, if you want to comfortably cool the space 5 above the floor, especially the time zone when you get up the next day (for example, around 7:00 am), enter the scheduled time of wakeup (for example, 7 am) into the controller 12 and set it. To do.

  In response to this, the control unit 3a acquires predicted temperature data for the next day from the server S via the Internet N.

  First, when the predicted temperature of the next day (for example, the average temperature from 7:00 am to 12:00 am) found from the predicted temperature data of the next day acquired in this way is equal to or higher than a predetermined value (for example, 30 ° C.), the control unit 3 a Control as shown in FIG. 4 is performed.

  The on-off valve 33a is opened from 11:00 pm on the day when the unit price of electricity becomes relatively low as midnight power, and a large amount of cold air is dried as much as possible by the dehumidifying function of the indoor unit 3 of the air conditioner from the underfloor outlet 33. The cold storage in the underfloor space 4 is started. Then, when the predicted temperature of the next day (for example, the average temperature from 0:00 am to 5:00 am) is 25 ° C. or higher (tropical night), a small amount of cold air is also blown out from the blowout unit 32 on the floor.

  Then, from 5 am to 7 am on the next day, the cool air blowing from the underfloor blowing section 33 is set to a small air volume, and the cold air blowing from the above floor blowing section 32 is also set to a small air volume.

  As a result, the floor space 5 is appropriately cooled and is in a comfortable state around 7:00 am on the next day after the set scheduled wake-up time.

  Further, after 7 am on the next day, since the cold energy stored in the underfloor space 4 is transmitted through the floor portion 1a, the cooling is unnecessary or slightly performed for a while.

  In addition, when the predicted temperature of the next day (for example, average temperature from 7:00 am to 12:00 am) found from the predicted temperature data of the next day acquired in this way is less than a predetermined value (for example, 30 ° C.), cold storage is not performed.

  It should be noted that under-floor cooling during normal times and air-conditioning cooling can also be performed by opening the on-off valve 33a of the under-floor blowing section 33 or opening the on-off valve 32a of the above-floor blowing section 32 to cool air from these. Can be performed by blowing out.

  Further, the underfloor space 4 has a heat insulating structure in which a basic heat insulating material 10 is attached to the basic side wall concrete 1c.

  For this reason, underfloor heating / cooling with high energy efficiency can be performed without leaking the heat of the warm air or cold air in the underfloor space 4 as much as possible outdoors.

  The indoor unit 3 of the air conditioner has a dehumidifying function.

  For this reason, it is not necessary to install a separate dehumidifier in the space 5 on the floor, and it is possible to perform dehumidification during the cooling operation in summer when the humidity is high in Japan.
