Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to an air conditioning structure that makes it possible to take out high-temperature air by changing the directions of the heat storage flow path and the heat storage extraction flow path.

[Background technology]

An air conditioning structure is known in which a storage tank is loaded with a heat storage material such as gravel or crushed stone, the heat is stored in the heat storage material using hot air, and the stored heat is taken out as hot air when necessary. In conventional devices, the flow path is common for storing heat in the heat storage material and for removing the stored heat. Note that during heat storage, heat is taken away by the heat storage material at the inlet, so the temperature of the heat storage material at the outlet becomes relatively low. Therefore, when air is introduced during extraction, the air passes through the heat storage material at the outlet portion before being discharged and loses heat, making it difficult to obtain high-temperature air.

[Purpose of invention]

The present invention aims to provide an air conditioning structure that can solve the above-mentioned problems by arranging the air flow paths for heat storage and heat extraction in different directions.

[Disclosure of invention]

An embodiment of the present invention will be described below based on the drawings.

1 to 3, the air conditioning structure of the present invention has a fan duct 7 in a storage tank 3 loaded with a heat storage material 2.
The first air flow path 4 and the second air flow path 5 that share the same air flow are communicated with each other.

In this embodiment, the storage tank 3 is installed under the floor by attaching a heat insulating material 13 to the lower surface of the floor plate F below the room R, the inner surface of the cloth foundation 11 surrounding the floor plate F, and the subfloor surface 12 below the floor plate F. The storage tank 3 has a first ventilation hole 9 on one inner surface facing the cloth foundation 11 and a second ventilation hole 1 on the other surface.
0 is open.

The heat storage material 2 is a granular material having heat storage properties such as gravel or crushed stone, and is
0 is loaded between porous partition plates 31 and 32 that stand upright with a small gap between them.

The first air flow path 4 is a duct 17 leading from the hot air outlet of the solar heat collector C to the first vent 9.
and a duct 19 communicating from the second vent 10 to the return port of the solar heat collector C, with the solar heat collector C interposed therebetween. In addition, a fan 8 that can send air only in one direction, for example, from the solar heat collector C to the storage tank 3, is attached to the duct 17 in the first air flow path 4, and the first air flow path 4 is Each end of the flow path 4 communicates with first and second vents 9 and 10.

The second air flow path 5 is connected to the duct 17 by the fan 8
Fan 8 from the ventilation port 25 that opens into the room R above the

, a lower part 36 of the duct 19 communicating with the second vent 10, a lower part 37 of the duct 19 communicating with the first vent 9, and a duct branching from the lower part and opening at the floor plate F of the room R. 39, and thus both ends of the second air flow path 5 communicate with the first and second vent holes 9 and 10.
Further, the ventilation port 25 is provided with a switching valve 26 that closes the duct 17 at the upper part of the ventilation port 19 when the ventilation port 25 is opened. Similar switching valves 27 and 28 are also arranged at the intersection,
The first and second air flow paths 4 and 5 share the space between the ventilation port 25 of the duct 17 and the branch point of the duct 35, and the air flow only occurs in one direction, for example, downward. The fan duct 7 has a fan 8 interposed therebetween. Note that the switching valve 26, 2
7 and 28, as shown in FIG. 3a, the air passing through the fan duct 7 and the heat storage material 2 from the first vent 9 is sucked in from the second vent 10, and then passed through the duct 19 to collect solar heat. A first air flow path 4 leading to the heating device C can be formed, and the switching valves 26, 2
7, 28, as shown in FIG. A second air flow path 5 is formed that circulates air from the port 9 into the chamber R through the duct 39. Therefore, the first vent 9 communicates with the downstream end of the air flow passing through the first air flow path 4, and the second vent 10 communicates with the downstream end of the second air flow path 5. In the storage tank 3, the air flowing through the second air flow path 5 is
The air flowing through the first air flow path 4 flows in opposite directions to each other.

By operating the switching valves 26, 27, and 28 to circulate the air through the first air flow path 4 as shown in FIG. Heat can be stored in the heat storage material 2 by discharging it from the vent 9 of the heat storage material 2.

Furthermore, at night, etc., as shown in Figure 3b, by circulating the air through the second air flow path 5, the heat storage material becomes an air flow path in the opposite direction to the flow path during heat storage. 2 and circulates between chamber R and chamber R. Therefore, since the air flow is opposite during heat storage and heat storage extraction, high temperature air flows in during heat storage,
A heat storage material 2 near the first vent 9 on the high temperature side,
When extracting heat storage, air flows in the opposite direction and heat exchange is possible on the downstream side, thus making it possible to extract high-temperature air. In addition, since the fan duct 7 is shared, piping is simplified, and the fan 8 only needs to rotate in one direction, reducing the effort required for wiring work.

[Effect of idea]

As mentioned above, the air conditioning structure of the present invention allows air to flow in opposite directions between the air flow path to the heat storage material and the flow path for heat storage extraction, making it possible to take out high-temperature air and improve the room temperature. In addition to being useful for air conditioning, the equipment can be simplified by using a common fan duct.

In addition, in the structure of the present invention, as illustrated in FIG. 4, by forming the floor plate 10 using a heat conductive material, the chamber R1 above the storage tank 3 is heated by the heat stored from the heat storage material 2, and By providing ventilation holes 25 and 29 for heat storage extraction in the adjacent room,
It can be modified in various ways, such as by using the warm air to air-condition the adjacent room.
