Description

[Detailed Description of the Invention] The present invention relates to a heat storage material unit used in a heating and cooling system.

From the standpoint of energy conservation, heating and cooling systems that utilize solar heat and other waste heat are being actively researched and developed, and some have even been put into practical use.

FIG. 1 is an explanatory diagram of one embodiment of a heating and cooling system using solar heat. In the figure, 1 is a heat collector, 2 is a heat storage material, 3 is a floor material, and 4 is a heat insulating material.

Pipes 5 are buried in the heat storage material 2 in all directions.

The solar energy collected by the heat collector 1 forms warm air,
The hot air is sent through pipes 1 and 8 to pipe 5 in heat storage material 2 by opening valves C and activating fan 6.

Since the heat storage material 2 is made of concrete and has a large heat capacity, it absorbs heat from the hot air sent into the pipe 5 and stores the heat.

Then, the heat is sequentially radiated into the room through the flooring 3 to heat the room.

Furthermore, when the temperature of the outside air is lower than that inside the room, such as on a summer night, by closing valve A and opening valves B and C to operate fan 6, the cold outside air will flow through pipe 5. The heat inside the room is taken away via the heat storage material 2 and the flooring material 3 to cool the room.

A unit used in such a system is a unit t)S in which hollow pipes connected in a lattice shape are embedded in a heat insulating material made of synthetic resin foam with a closed cell structure, and the ends of the hollow pipes are opened. Utsukai Showa 55-1097
11 (see FIG. 10).

However, since the disclosed unit has a flat side surface, gaps may occur when the units are assembled due to dimensional errors during unit molding, and small openings may occur on the side surface. Since a large number of units are provided, if the openings of adjacent units are slightly misaligned, inconveniences such as extremely poor air circulation will occur.

Furthermore, when using a fan, etc. to forcefully send a fluid such as air, such a unit makes it difficult for the fluid to flow, increasing the fan's air resistance, which may consume more electricity, etc., or cause the fan to overflow. Shorten the life of motors, etc.
After that, the motor car S is exhausted.

The present invention improves the heat storage material used in such heating and cooling systems so that it is easier to install, and consists of a plate with a large heat capacity and a protrusion for fitting on the side and a corresponding recess. , this plate state is provided with a main passage with a large cross-sectional area that can communicate with each other when fitted with another unit, and secondary passages with a small cross-sectional area branched from this main passage, and the above-mentioned The gist of this invention is a heat storage material unit in a heating and cooling system, characterized in that the main passage is provided from a protrusion to a recess.

To explain the embodiment with reference to drawings, FIG. 2 is a perspective view of the main unit, which is made of a material such as concrete or ceramics that has a large heat capacity h5, is relatively strong and inexpensive, and can be manufactured into complex shapes.

Two sides of the unit are provided with protrusions 9, and the other two sides are provided with recesses 10 into which the protrusions 9 of other units fit.

A main passage 11 passes through the center of the unit from the protrusion to the recess 10, and from the main passage 11, a plurality of (six in the figure) subsidiary roads 12b5 branch off inside the unit.

The tip of the secondary road 12 may be a dead end, as shown in the cross-sectional view of FIG.

(f) Adjacent secondary roads may be connected.

The unit to be located at the end is as shown in Figure 4.
One end of the main passage 11 is rounded and bent by 90'' to connect to a symmetrical main passage of an adjacent unit.

Fig. 5 shows the arrangement of four typical units, in which the main passage 11 is connected in a U-shape, and hot air flows through the heat collector 1,
The heat is circulated through the fan 6 and the main passage 11 to the heat collector 1 again.

Further, the warm air evenly enters the air passage 12 and heats and stores heat uniformly over the entire surface.

There are various arrangements of the secondary roads 12, and FIG. 6 is one example.

If the arrangement is as shown in FIG. 7, the end of the secondary road 12 of each unit does not have to be a blind hole, but the secondary road 12 ends up being a blind alley, and manufacturing is facilitated.

8. If the secondary roads 12 are arranged at right angles on both sides of the main passage 11, as shown in FIG.
As in the case shown in the figure, the secondary road 12 becomes a dead end due to the walls of adjacent units.

Furthermore, as shown in FIG. 9, the main passage 11 and the secondary road 12 of the unit may be shaped with one side open.

In this case, a heat insulating material or the like may be applied to the open side of the passage.

Of course, this can also be used upside down.

The main passage 11 and secondary road 12 in the present invention have a cross section f)
'5 It may be circular, rectangular, or half-shaped, or it may be made of a metal pipe with good thermal conductivity, such as aluminum, and then buried.

When metal pipes are used, heat can be transmitted to every corner of the heat storage material more quickly61, which greatly improves efficiency.

The present invention is as described above, and by appropriately combining the protruding part and the recessed part, it can be installed, for example, under the floor without any gaps, and while hot air is sent through the main passage, heat is distributed evenly by the secondary road. Heat can be stored evenly.

In addition, since the main passage is provided from the protruding part to the recessed part of the unit, when the units are combined, even if the opening of the main passage is slightly shifted, the units will fit together. There is no need to worry about hot or cold air escaping.

In addition, since the fan has low blowing resistance, it is possible to prevent wastage of electricity, etc., and it does not shorten the life of the motor.

By making it into a unit, it becomes possible to mass produce it in a factory, resulting in low cost, easy construction, and even if it is damaged, only the damaged part can be replaced. have

As mentioned above, the system configured with the unit of the present invention can also be used for cooling during the summer.
