2. Description of the Related Art A floor storage type thermal storage air conditioning system has a double floor structure in which a floor panel is arranged above a concrete floor slab. An air outlet is arranged in the floor panel and conditioned air is supplied into the double floor. The basic configuration is that air is supplied and heat is stored by a floor slab or air-conditioned by release from an outlet.

An example of such a floor blowing type thermal storage air conditioning system is disclosed in Japanese Patent Application Laid-Open No. H11-101476. In the system described in this publication, each space of the double floor of the floor and the space above the ceiling is connected to an air conditioner, and a switching damper is provided at each outlet of the double floor of the floor and the space above the ceiling, and these switchings are performed. The operation of heat storage and air conditioning can be performed by operating the damper. The outlets are placed at appropriate intervals on the floor panel,

That is, conditioned air is blown into the room from all outlets during indoor air-conditioning, and conditioned air is not supplied from the outlet to the room during night-time heat storage air conditioning. For this reason, for example, when the room is divided into a plurality of sections by partitions or the like, and a meeting or the like is held only in a part of the room at night, if the indoor air-conditioning mode is set, the air-conditioning air is additionally blown out from all the outlets. Therefore, if the air conditioner is set to the thermal storage air conditioning mode, the supply of the conditioned air is completely eliminated. Therefore, when the indoor air-conditioning mode is set, the air-conditioned air is wasted, and when the thermal storage air-conditioning mode is set, the indoor air-conditioning is not performed even if a person remains in a part of the room.

As described above, in the conventional system, only the switching to the air conditioning of the whole room or the heat storage operation can be selected, and there is a problem that the conditioned air is wastefully consumed.

In view of the above, the present invention provides a frame heat storage floor air outlet in which each of the air outlets independently opens and closes a flow path, and supplies air-conditioned air to a predetermined zone in a room even when heat is stored.

FIG. 5 is a schematic diagram of a skeleton heat storage system for showing air conditioning when the outlet 1 is installed on a floor panel 52 of a building.

As described above, the concrete slab 51
The air outlet 1 is installed on a floor panel 52 disposed above the air conditioner 10, and air is supplied to the ceiling panel 53 from the air conditioner 10.
A return air port 53a for returning to the air is opened. The air conditioner 10 disposed outside the building includes a heat exchanger 10a and a fan 10b.
The supply path 10c from the air conditioner 10 is connected to a space between the slab 51 and the floor panel 52. Return air ducts 11 and 12 are connected to a space above the ceiling between the ceiling panel 53 and the ceiling slab 54 and a space below the floor between the slab 51 and the floor panel 52, respectively. The main return air duct 13 is connected to the air conditioner 10. The return air duct 12 incorporates a backflow prevention damper 14.

FIG. 6 is a schematic diagram showing the structure of the backflow prevention damper 14. As shown in FIG.

The backflow prevention damper 14 is composed of a metal damper plate 14b rotatable left and right in the drawing to the return air duct 12 by a hinge 14a, and a magnet 14c for attracting the tip of the damper plate 14b. It is a thing. In FIG. 6A, the damper plate 14b is used.
Is adsorbed by the magnet 14c and the flow path in the return air duct 12 is closed. The force constraining the damper plate 14b to the closed position is the attraction force of the magnet 14c, and is set to be closed when the pressure of the air flowing from the underfloor space to the return air duct 12 is low. When the pressure of the flowing air exceeds a certain value, the rotational force of the damper plate 14b due to the air pressure becomes larger than the attraction force of the magnet 14c, and the damper plate 14b rotates rightward as shown in FIG. To open the flow path in the return air duct 12. That is, when the opening 1d of the air outlet 1 is opened and the conditioned air from the air conditioner 10 flows to the indoor side, the pressure applied to the damper plate 14b is small, so that the flow path is closed as shown in FIG.
When the opening 1d of the outlet 1 is closed, the pressure applied to the damper plate 14b increases, and the flow path is opened as shown in FIG.

In the above configuration, the power generated by the solar cell 3a receiving indoor lighting and morning sunlight is stored in a capacitor 4c connected to the solar cell 3a by a cable 4b. Is a driving power source for the movable part of the outlet 1. Then, when the light sensor 3b receives room illumination or sunlight, the signal is input to the controller circuit section 4a provided on the circuit board 4, and the drive motor 6 is operated to lower the opening / closing plate 5 to the state shown in FIG. . As a result, the opening 1d on the bottom surface of the chamber housing 1c is opened, and the conditioned air from the air conditioner 10 is opened.
d through the hole 2a of the grill 2 and is blown into the room.
FIG. 5 described above shows this indoor air-conditioning. The air-conditioning air supplied from the air conditioner 10 to the underfloor space flows from the air outlet 1 to the indoor side, so that the pressure applied to the damper plate 14b of the backflow prevention damper 14 is reduced. Becomes smaller, and FIG.
Is maintained in the closed position as shown in FIG. Therefore, the conditioned air supplied into the room from the outlet 1 is
Flows into the space above the ceiling from the return air port 53a of the
From the main air return duct 13 to the air conditioner 10. In this way, the air conditioning of the room by the air conditioner 10 is performed by the lowering operation of the opening / closing plate 5 of the outlet 1.

On the other hand, when the indoor lighting is turned off or the sunlight disappears, the output of the optical sensor 3b is input to the controller circuit section 4a, and the output shaft of the drive motor 6 rotates in the reverse direction to open and close as shown in FIG. The plate 5 is raised.
The opening / closing plate 5 is lifted to raise the chamber housing 1c.
, The opening 1d is closed, and the flow of the conditioned air to the indoor side stops. Accordingly, the pressure in the underfloor space rises, and the backflow prevention damper 14 opens as described above in FIG. 6B to communicate the underfloor space with the return air duct 12 as described above. FIG. 8 shows the flow of the conditioned air in the case of such an operation. The conditioned air passes through the underfloor space, passes through the backflow prevention damper 14, the return air duct 12, and the main return air duct 13, and is supplied to the air conditioner 10. Repeat the cycle back to. Therefore, heat is stored in the concrete slab 51 by the conditioned air, and such heat storage air conditioning is continued at night.

As described above, when the light sensor 3b detects the illumination light or the sunlight, the air conditioner is switched to the indoor air conditioning, and when the light sensor 3b detects that the light is turned off and there is no sunlight, the air conditioner is switched to the heat storage air conditioning by the slab 51. Therefore, indoor air-conditioning is performed from morning to evening, and even during nighttime, indoor air-conditioning is continued as long as the lighting is on, and when the light goes out, heat is stored in the slab 51 until the next morning.

Here, when the room is partitioned by partitions, booths, or the like, if there is illumination light only in the partitioned area, the air outlet 1 included in this location is detected by the light detection of the optical sensor 3b. Since the open / close plate 5 is lowered as shown in FIG. 5, conditioned air is supplied from the outlet 1. That is, even when the lighting is turned off at night, if the lighting is continued only in a certain area, the conditioned air is blown into the room from the outlet 1 included in this area. Therefore, when a work or a meeting is held using only a certain part without using the whole room, only the used area can be air-conditioned, and the place where there are no people is not wastefully air-conditioned.

During air conditioning by a part of the air outlets 1 in the room, the amount of conditioned air flowing toward the backflow prevention damper 14 in the underfloor space can be increased to some extent. Therefore, the damper plate 14b can be slightly opened, and the conditioned air passing through the underfloor space can be returned from the backflow prevention damper 14 to the air conditioner 10. Thereby, the local air conditioning in the room and the operation of heat storage for the slab 51 can be simultaneously performed, and the indoor air conditioning and the heat storage air conditioning by the air conditioner 10 can be effectively operated.

[0035]

According to the present invention, it is possible to switch between indoor air conditioning and heat storage air conditioning by opening and closing the opening and closing mechanism without the need for an external power supply, and by opening or closing any air outlet. The entire room can be air-conditioned or locally air-conditioned. Therefore, it is possible to use the air conditioner without using the entire room exclusively for air conditioning or heat storage air conditioning as in the related art. For example, in a predetermined zone in the room, air can be supplied and air-conditioned even during heat storage air conditioning.
