Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a temperature environment control device that uses heat accumulated in a structure or the like for cooling and heating.

"Prior Art" When cooling or heating the interior of a structure, some or all of the heat to be used for cooling or heating during the day is stored in water at a relatively low electricity rate at night. A method of storing heat as ice heat storage has been conventionally performed.

Further, recently, a method of cooling or heating a building itself as a heat storage material and utilizing the amount of stored heat has been attempted.

In the case of so-called body heat storage that uses the body of the structure itself, a pipe is embedded and cold water or hot water is passed through the pipe to store heat in the body around the pipe.

"Problems to be solved by the invention" However, in the case of the conventional body heat storage, heat is naturally released by storing heat by embedding a pipe.
As the stored heat continues to be used, the amount of heat dissipated between the upper floor and the lower surface of the floor is different, so the temperature of either surface approaches room temperature quickly. At this time, there is still residual heat in the slab near the other surface, and it is desirable to use the residual heat in this slab for both the upper floor and the lower floor at the same time.

Therefore, in the present invention, the residual heat amount of the heat storage amount is positively transferred to the thickness direction of the slab, and thus the heat storage amount of the slab can be effectively used in both the upper and lower floors. It is intended to provide a temperature environment control device.

"Means for Solving the Problem" The temperature environment control device of the present invention is configured to store cold heat in a floor slab of a reinforced concrete building and use the stored cold heat amount for heating and cooling in the upper and lower floors of the floor slab. A temperature environment control device, in which a pipe for passing the cold storage heat medium is embedded in the floor slab, and the lower surface of the floor slab is covered with a steel plate such as a deck plate, and in the floor slab. A grid-like reinforcing bar is embedded on the upper surface side over substantially the entire surface of the floor slab, and a large number of connecting bars connecting the grid-like reinforcing bar and the steel plate are arranged in the floor slab along the thickness direction thereof. The connection bar facilitates heat transfer between the lattice-shaped reinforcing bar and the steel plate.

"Operation" In the temperature environment control device of the present invention, a cold storage heat medium such as cold water or hot water is passed through a pipe embedded in the floor slab to cool or heat the floor slab from the inside to store cold or heat. The floor slab that has stored or stored heat cools or radiates heat naturally to both the upper surface side and the lower surface side of the floor slab, and contributes to cooling or heating both upper and lower floors.

In general, the amount of heat radiated from the floor slab to its upper surface, that is, the upper floor, and the amount of heat radiated to the lower surface, that is, to the lower floor, are not always equal, and as a result, the temperature on the upper surface side and the lower surface side of the floor slab is Although there will be a difference, in the present invention, the grid-like reinforcing bars embedded in the upper surface side of the floor slab, the steel plate covering the lower surface, and a large number of connecting bars connecting them are used in the thickness direction of the floor slab. Heat transfer is promoted, and therefore the temperature difference between the upper and lower surfaces of the floor slab is suppressed. For example, in general, the amount of natural heat released from the floor slab that has accumulated heat during heating is larger on the lower surface side than on the upper surface side, so the temperature of the floor slab decreases faster on the lower surface side than on the upper surface side. As a result, a large temperature difference usually occurs between the upper and lower surfaces of the floor slab. However, in the present invention, when such a temperature difference occurs, a heat transfer action occurs from the grid-shaped reinforcing bars to the steel sheet via the connecting bar, which suppresses the temperature decrease of the steel sheet and suppresses the temperature difference between the upper and lower sides. Will be done.

In the present invention, the lattice-shaped reinforcing bars embedded on the upper surface side of the floor slab, the steel plates covering the lower surface, and the connecting bars connecting them are all made of steel material, so that they are naturally heat conductive. Therefore, the above heat transfer action is naturally performed efficiently.

[Example] Hereinafter, a temperature environment control device of the present invention will be described with reference to Figs.
It will be described with reference to the drawings.

In the figure, reference numeral 1 is a reinforced concrete building, and reference numeral 2
Is a floor slab that constitutes the floor of the building 1, and reference numeral 5 is the entire temperature environment control device configured for the floor slab 2.

A plurality of pipes 3 are embedded in the floor slab 2 at predetermined intervals to cool or heat the floor slab 2 by passing a cold storage medium such as cold water or hot water.

In addition, the lattice-shaped reinforcing bars 4 are embedded over the entire upper surface side of the floor slab 2, and the lower surface of the floor slab 2 is covered with a steel plate (deck plate having ribs in this embodiment) 2a. ing. Further, a large number of connecting bars 4b are arranged along the thickness direction of the floor slab 2, and the connecting bars 4b connect the grid-like reinforcing bars 4 and the steel plate 2a. Lattice rebar 4, above
Each of the steel plate 2a and the connecting bar 4b is made of a steel material widely used as a normal building material, and naturally has good heat conduction performance.

Further, the temperature environment control device 5 of the present embodiment is provided with a ceiling louver 6 and rotary vanes 7.

The ceiling louver 6 is composed of a plurality of rectangular blade bodies 6a, and the blade body 6a has a rotating shaft.
It is set to open and close like a blind with 6b as the central axis. The ceiling louver 6 is installed slightly below the floor slab 2. The opening / closing operation of the ceiling louver 6 can be performed manually or automatically by providing a control device.

The rotary vane 7 is rotatably provided on the lower surface of the floor slab and can generate a forced airflow as shown by an arrow I in the drawing.

When the temperature environment control device 5 of this embodiment is used, cold water in summer and hot water in winter are passed through the pipe 3 embedded in the floor slab 2 using relatively inexpensive nighttime electric power to store heat in the floor slab 2. To do.

Then, the temperature environment inside the room is controlled by releasing the amount of heat stored in the floor slab 2 into the room.

At this time, the grid-like reinforcing bars 4 embedded on the upper surface side of the floor slab 2 and the steel plate 2a covering the lower surface of the floor slab 2
And, the so-called heat bridge will be formed by the connecting muscle 4b connecting them, thereby,
Heat transfer from the upper surface side of the floor slab 2 to the lower surface side is promoted, and the residual heat of the upper surface side of the floor slab 2 is effectively transferred to the lower surface side,
As a result, heat is effectively dissipated not only in the upper room but also in the lower room.

Furthermore, an indoor thermometer is installed to control the opening / closing of the ceiling louver 6 and the rotation of the rotary vanes 7 to cool the wind using the amount of heat stored in the body.
It can control hot air, natural draft, and radiant heat.

According to the temperature environment control device 5 of the present embodiment, the following excellent effects can be achieved.

Heat is stored in the floor slab 2 by passing cold and hot water through the pipe 3 through the floor slab 2 and controlling the temperature environment in the room by using this heat storage amount. Heat can be moved in all directions within the floor slab 2 by the embedded lattice-shaped reinforcing bars 4 having good heat conductivity. In particular, since the grid-shaped reinforcing bars 4 and the steel plate 2a are connected by the connecting bars 4b to form a heat bridge, the residual heat remaining above the floor slab 2 is moved to the lower surface of the floor slab 2. As a result, the residual heat in the floor slab 2 can be effectively used.

Then, by effectively utilizing the heat storage amount, the cost for cooling and heating can be reduced.

Further, by using the ceiling louver together, it is possible to adjust the heating and cooling and provide a comfortable living space.
