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 collector 1 forms warm air,
The hot air is sent to the pipe 5 in the heat storage material 2 through the pipes 7 and 8 by opening the valves A and C and operating the fan 6.

The heat storage material 2 is made of concrete, for example, and has a large heat capacity, so 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.

The present invention improves the heat storage material used in such heating and cooling systems so that it is easier to install and increases its thermal efficiency.It is equipped with a protrusion for fitting on the side and a corresponding recess. This plate-like body has a main passage formed of a material with good thermal conductivity such as metal that can communicate with other units when fitted with another unit, and a main passage from this main passage. The gist of the present invention is a heat storage material unit in a heating and cooling system, which is characterized by being provided with branched fin members made of a material with good thermal conductivity such as metal.

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

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

A main passage 11 is passed through the center of the unit, so that when the units are connected, the main passages are connected to each other to form a fluid passage.

The main passage 11 has a large cross-sectional area to reduce the blowing resistance of the fan.

A plate-shaped fin member 12 branches from the main passage 11.

The fin member 12 is made of a material with good thermal conductivity, such as metal.

Although FIG. 3 is a cross-sectional view, the tip of the fin member 12 may be buried within the unit.

Further, as shown in a modification shown in FIG. 4, the fin member 12 may be of a biplane type.

Furthermore, as shown in the modified example of FIG. 5, the fin member 12
may be of a bent type.

In the case of FIGS. 4 and 5, the contact area between the fin member 12 and the heat storage material is larger than in the case of FIG. 3, and the heat exchange efficiency is improved.

As shown in FIG. 6, the unit to be located at the end under the floor bends one end of the main passage 11 with a radius and connects it to the symmetrical main passage of the adjacent unit.

It is better to minimize the bending loss by making the radius of curvature as large as possible at this curved portion.

Figure 7 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.

At this time, the hot air evenly transfers heat to the fin member 12, and heats up and stores heat uniformly over the entire surface.

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 sending hot air through the main passage, the fin member dissipates heat (in summer, it absorbs heat). ) Can take up a large area and has a very good heat storage effect.

Heat storage materials generally have low thermal conductivity and low temperature conductivity, so it takes time to heat every corner of the heat storage material when only hollow pipes through which warm air is used are used.

Since the heat collection time, that is, the heating time of the heat storage material (the time during which hot air flows) is limited, it is possible to store heat uniformly and efficiently by using fin members made of materials with good thermal conductivity such as metal. can.

Furthermore, the unit itself is easy to manufacture.

Furthermore, since warm air does not enter the fin member, the blowing resistance of the fan is small, the fan power can be reduced, and waste of electricity, etc. can be prevented, and the life of the motor will not be shortened.

By unitizing it, it becomes possible to mass-produce it in a factory, which results in lower costs. It also has the advantage of being easy to install, and even if it is damaged, only the damaged part can be replaced. .

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