As a heat medium used for heat exchange of the air conditioner 4, a liquid such as water or oil or a gas such as steam or nitrogen gas is used depending on the purpose of use.

[0003]

However, although an air conditioner can be installed in an indoor space to perform air-conditioning of the indoor space, the air conditioner occupies a part of the indoor floor area. Occurs. For example, when installing equipment such as desks and chairs on the floor of an indoor space, there is a problem that the air conditioner becomes an obstacle and the equipment and the like must be installed in other places without difficulty. Therefore, the conventional air conditioner has a drawback that the floor area of the structure cannot be effectively used.

[0004] In addition, there is a bias in the heat distribution in the building, and when trying to make the temperature in the building uniform, it has been necessary to provide a vent hole for blowing air at a portion where a heat load is applied.
However, when the arrangement of the equipment and the like in the indoor space is changed, there is a disadvantage that the ventilation port once installed cannot be moved, and in some cases, the heat distribution in the building is further biased.

The present invention focuses on the above-mentioned conventional problems and provides an air conditioner using a heat exchange floor panel capable of effectively utilizing an indoor space by utilizing a floor member and an underfloor space, and an arrangement position according to a heat load. It is an object of the present invention to provide an air conditioner using a heat exchange floor panel capable of changing the temperature.

[0006]

In order to achieve the above object, an air conditioner using a heat exchange floor panel according to the present invention has a suction member and an air outlet formed in a floor member forming an underfloor space in a building. In addition, a fan for circulating air between the underfloor space and the indoor space is provided through the suction port and the outlet, and a floor panel having a heat transfer tube portion is laid on at least one of the suction port and the outlet, and the floor panel is provided. Was configured to supply a heating medium.

Further, the heat exchange floor panel according to the present invention has the same size as the other floor panels constituting the floor member, so that the arrangement position can be changed according to the heat load.

[0008]

According to the above arrangement, a supply pipe and a return pipe connected from an external air conditioner to the underfloor space are connected to a floor panel having a heat transfer pipe section at at least one of the suction port and the air outlet.
Circulate heat medium for air conditioning. The heat transfer tube section changes to a target temperature by the circulation of the heat medium, and the air around the heat transfer tube section is also converted to the target temperature by the heat transfer action. The heat medium whose temperature has been changed by the heat exchange action after passing through the heat transfer tube section passes through the reflux pipe, returns to the air conditioner in the outside of the building, is adjusted to the target temperature, and is again supplied to the supply pipe as a heat medium for air conditioning. . Simultaneously with this operation, a fan that circulates air between the underfloor space and the indoor space is rotated, and air is circulated between the indoor space and the underfloor space via a suction port or an outlet having a heat transfer tube. At this time, when the air passes through the suction port or the air outlet, the air is converted to a target temperature. Therefore, if this circulation is continued, the building is air-conditioned to the target temperature.

Further, since the heat exchange floor panel has the same size as other floor panels constituting the floor member, it can be arranged anywhere on the floor member. Therefore, when the heat distribution in the building is biased, the location of the heat exchange floor panels can be changed in accordance with the heat load to improve the bias in the temperature distribution in the building.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, specific embodiments of an air conditioning system and apparatus using a heat exchange floor panel according to the present invention will be described in detail with reference to the drawings.

FIG. 1 is a structural explanatory view of an air conditioner using a heat exchange floor panel according to an embodiment, FIG. 2 is a plan view of the heat exchange floor panel, and FIG. 3 is a structural explanatory view of the heat exchange floor panel. ing.

First, as shown in FIG. 1, a floor member is laid in parallel with a floor slab 1 on the bottom of the building, and the building is vertically divided into two parts by the floor member. The upper side partitioned by the floor member is used as the indoor space 2, and the lower side is used as the underfloor space 3 in which the air conditioning member is arranged. The floor member is configured by laying a large number of square flat panel panels 7, and a part thereof is provided with a suction port and a blow port that allow air to flow in two spaces. The fixing and holding of the floor member are performed by providing a support leg 8 between the floor slab 1 and the floor member.

The outlet panel 9 serving as an outlet has the same size as the flat panel 7, and has a mesh-shaped hole 10 for blowing air from the underfloor space 3. In the underfloor space 3 side,
A fan 11 having a plurality of blades attached to an electric motor is provided. When the electric motor is energized and the fan 11 is rotated, the air in the underfloor space 3 is blown out to the indoor space 2. Thereafter, the air blown into the indoor space 2 flows through the suction port again into the underfloor space 3 due to the pressure difference between the two spaces. When the fan 11 of the blow-out panel 9 is continuously rotated in this manner, the building air circulates between the indoor space 2 and the underfloor space 3.

The heat exchange floor panel 5 serving as the suction port has the same size as the flat panel panel 7 like the blow-out panel 9, and a plurality of slits 12 are formed in the same direction as shown in FIG. doing. Further, on the underfloor space 3 side of the heat exchange floor panel 5, a heat medium supply port 13 is provided at any one of the ends of the sides perpendicular to the longitudinal direction of the slit 12, and the heat medium supply port 13 A heat medium recirculation port 14 is provided at the angular position. The heat exchange floor panel 5
Heat medium supply port 13, heat medium supply header section 15 at the side where heat medium supply port 13 is provided, heat medium return port 14, and heat medium return header section at the side where heat medium return port 14 is provided 16 and a plurality of heat medium passages 17 connecting them.
It is composed of The heat medium supply header section 15, the plurality of heat medium flow paths 17, and the heat medium recirculation header section 16 are all hollow, and the heat medium flows through the internal flow path from the heat medium supply port 13 to the heat medium recirculation port 14. It can freely flow. Although not shown, an air conditioner 4 for supplying and reducing a heat medium for air conditioning is provided in the building outdoor part, and a heat medium supply pipe 18 and a heat medium recirculation pipe 19 are provided therefrom to form an underfloor space in the building. Piping is on the 3 side. The heat medium supply pipe 18 and the heat medium return pipe 19 on the underfloor space 3 side are tubes 20
Are connected to the heat medium supply port 13 and the heat medium recirculation port 14 of the heat exchange floor panel 5 respectively.

In the air conditioning system using the heat exchange floor panel 5 configured as described above, for the purpose of, for example, heating a room, first, the air conditioner 4 in the outside of the building first uses the water as a heat medium. Is heated to a desired temperature. The hot water that has reached the target heating temperature by heating proceeds to the underfloor space 3 through the heat medium supply pipe 18 due to the pressure from the air conditioner,
It is introduced into the heat medium supply port 13 of the heat exchange floor panel 5 via the tube 20. The hot water is first filled in the heat medium supply header section 15 and then dispersed and flows into the plurality of heat medium flow paths 17. The heat medium flow path 17 changes to a target heating temperature by a heat transfer action from the hot water. Further, since a plurality of slits 12 are provided around the plurality of heat medium flow paths 17 at the target heating temperature, a large amount of air around the heat medium flow path 17 can also transfer heat to the target heating temperature. Is converted to The hot water, which has passed through the heat medium flow path 17 and whose temperature has been lowered by heat exchange, merges again at the heat medium recirculation header 16 and flows from the heat medium recirculation port 14 to the heat medium recirculation pipe 19 via the tube 20. . After that, the air conditioner 4
Then, it is heated again and supplied again to the heat medium supply pipe 18 as warm water for air conditioning.

Simultaneously with this operation, the electric motor provided in the blow-out panel 9 is energized, and the fan 11 is rotated so as to blow air toward the indoor space 2. When such work is continued, the air in the indoor space 2 is turned into the slit 1 in the heat exchange floor panel 5 in order to compensate for the pressure difference with the underfloor space 3.
Attempts to move from 2 to underfloor space 3. At this time, the air that passes through the slit 12 and enters the underfloor space 3 through the heat transfer function from the heat medium flow path 17 adjacent to the slit 12 is converted to a target heating temperature. The heated air that has entered the underfloor space 3 is blown into the indoor space 2 by the operation of the fan 11 of the blowout panel 9. The blown-out heating air diffuses in the indoor space 2 to heat the indoor space 2. Thereafter, the air heated in the indoor space 2, that is, the air that has radiated heat in the indoor space 2 and lowered in temperature, is subjected to the heat exchange floor panel 5.
And is again converted into heating air by the heat transfer function and blown out from the blow-out panel 9 into the indoor space 2. By continuing such a circulation, the inside of the building is converted to the target heating temperature.

The heat exchange floor panel 5 includes a heat medium supply pipe 18,
As long as it can be connected to the heat medium reflux pipe 19, any number of sheets can be used at any place in the room. In the connection method, the heat exchange floor panels 5 are individually connected to the heat medium supply pipe 18 and the heat medium reflux pipe 19 individually. Connected in parallel or multiple heat exchange floor panels 5
The heat medium supply port 13 and the heat medium recirculation port 14 are connected in a daisy chain, and the top and end heat medium supply ports 13 and the heat medium recirculation port 14 are connected to the heat medium supply pipe 18 and the heat medium recirculation pipe 19, respectively. It is also possible to use a system or a combination of a series and a parallel system. Therefore, it is possible to improve the uneven heat distribution in the room or to locally change the temperature of a certain part of the room. For example, in the case of a room having a glass window 21 in winter, heat is transmitted to the glass window 21 more easily than the surrounding wall 22, so that heat of the indoor space is released to the outside air through the glass window 21 by the heat transfer function, and the surroundings of the indoor window Of the temperature decreases. Here, when the heat exchange floor panel 5 is installed on the floor around the window, a part of the room directly heats the room air around the window by radiating action to reduce the temperature drop around the window. Furthermore, since the heat exchange floor panel 5 serving as the suction port sucks and heats the room air around the window, the uneven heat distribution in the room due to the heat transfer effect of the glass window 21 can be improved. Further, if the heat exchange floor panel 5 is installed at a point where the desk or chair is installed in the room, the comfort of the indoor worker can be improved by the above-mentioned radiation action.

In FIG. 3, the heat exchange floor panels 5 are all made of the same material. However, if the heat medium supply port 13 and the heat medium return port 14 are changed to another member, for example, a rubber material, excessive stress is applied. Is not damaged even if it is applied, and the reliability of the entire apparatus is improved.
