DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a radiation cooling / heating system for a building.

[0002]

2. Description of the Related Art As one of cooling and heating systems in a building, there is a system using a floor or a ceiling of a room as a radiation heat transfer surface. As an example, Japanese Patent Application Laid-Open No. 8-296872 uses a floor of a room as a radiant heat transfer surface. That is, in this system, as shown in FIG.
The floor panel a is supported on the floor slab c at intervals by the columns b to form the space d, and the heat insulating material e is installed on the floor slab c to form the space d as an air-conditioned air passage. ing. The conditioned air from the air conditioner f installed on one side of the room flows into the conditioned air passage d from the discharge side through the duct g, flows through the conditioned air passage d, and flows through the conditioned air recirculation port h.
, And flows back to the suction side of the air conditioner f through the upper part of the room. At this time, the floor panel a is heated or cooled by the conditioned air flowing through the conditioned air passage d,
Used for indoor radiation cooling and heating.

Another example is disclosed in Japanese Patent Application Laid-Open No. 8-178372.
Japanese Patent Application Laid-Open Publication No. H10-209400 uses a ceiling of a room as a radiant heat transfer surface. That is, in this system, as shown in FIG. 24, a radiant panel 1 having a cold / hot water pipe j and a vent hole k connected to a cold / hot water heater i is installed under the ceiling slab m at intervals, and The cold / hot water from i is passed through a cold / hot water pipe j to cool or heat the radiant panel l for radiation cooling / heating, and at the same time, the cold / hot water returning from the cold / hot water pipe j to the cold / hot water heater i is led to the heat exchanger n. The outside air heat-exchanged in the heat exchanger n is transferred to the ceiling slab m and the radiation panel l.
The chamber formed therebetween is passed as an air-conditioned air passage o, and is allowed to flow out of the room through a vent hole k for cooling and heating.

[0004]

The above cooling and heating system has the following problems. (1). Since the radiant heat transfer surface is configured on either the floor or the ceiling only, there is a limit in increasing the radiant efficiency.If the radiant heat transfer surface is configured only on the floor, the radiation efficiency decreases when an object is placed on it. Would. (2). Both have a configuration in which conditioned air is supplied to the room in addition to cooling and heating by radiation, and therefore, are disadvantages when air is used as a heating medium for cooling and heating. A. It is difficult to make the temperature distribution uniform, b. Causing dust and ticks to be rolled up by the conditioned air,
c. There is a problem that the air of cooling and heating directly hits the skin. (3). In the former, the air-conditioning air that heats or cools the floor panel for radiant cooling and heating flows into the room, so the temperature of the air-conditioning air must be set as a temperature that maintains the indoor environment, and in order to enhance the radiant heat transfer effect There is naturally a limit in raising or lowering the temperature of the conditioned air. (4). In the former, because of the double-floor structure, a part of the floor slab can be lowered to increase the floor height or to install a duct for sending conditioned air from the discharge side of the air conditioner to the conditioned air passage. Sometimes needed. (5). In the latter case, it is necessary to install a radiant panel separately from the structure, so that the height above the ceiling becomes large, and the heat medium for cooling and heating uses both air and cold and hot water, so that the equipment cost increases. Therefore, an object of the present invention is to solve the above problems.

[0005]

In order to solve the above-mentioned problems, according to the present invention, an air passage is formed by a hollow portion formed in a structure of a building, and conditioned air of an air conditioner is circulated through the air passage. A radiant cooling / heating system is proposed in which a supply structure is used and at least a part of a surface of an air passage is used as a radiant heat transfer surface to a room.

According to the present invention, in the above structure, the structure having the radiation heat transfer surface is at least one of a structure forming the ceiling of the room, a structure forming the floor of the room, and a structure forming the wall of the room. We propose to be one.

According to the present invention, in the above structure, both surfaces of the structure are used as radiant heat transfer surfaces, or a heat insulating material is provided on one side of the structure and only the other surface is provided with radiant heat transfer surfaces. We propose to use it as a surface.

Further, according to the present invention, the adjacent hollow portions are communicated by the communication portion to form a serial air passage, or
It is proposed to form a parallel air passage by connecting adjacent hollow portions with a communication portion, or to form a serial air passage in the hollow portion by partitioning the hollow portion by a partition plate.

In the above invention, the conditioned air of the air conditioner is:
The air is circulated and supplied to the air passage formed by the hollow portion formed in the structure of the building, and does not pass through the room. The conditioned air circulating in the air passage heats or cools the structure constituting the air passage, and can perform radiation cooling and heating on the room from the radiation heat transfer surface of at least a part of the structure.

The air passage may be formed by connecting adjacent hollow portions with a communicating portion to form a series or parallel air passage or by dividing the hollow portion by a partition plate to form a series air passage in the hollow portion. The degree of freedom in design can be increased, for example, the length of can be appropriately adjusted.

[0011]

Next, an embodiment of the present invention will be described with reference to the drawings. 1 to 3 show a first embodiment of a radiation cooling and heating system of the present invention, and FIG.
FIG. 2 is a vertical sectional view showing a part of a certain floor, and FIG.
FIG. 3 is a sectional view taken along line A-B of FIG. 2. Reference numeral 1 denotes a living room, 2 denotes a storage room adjacent to the living room 1, and an air conditioner 3 is stored in the storage room 2. The ceiling C and the floor F of these chambers 1 and 2 are constituted by hollow slabs 4, and the hollow slab 4 is provided with a large number of hollow portions 5 oriented in the direction of the chambers 1 and 2. These hollow portions 5 are connected to each other by a communication port 6 on each end side of the hollow slab 4 opposite to the storage room 2. Therefore, the pair of hollow portions 5 a and 5 b are connected to the storage room 2. From one end to the other,
A series air passage 7 that is folded back to one end is formed. On the other hand, on the lower side of the hollow slab 4 of the ceiling C of the storage room 2, a pair of ducts 8 are provided in a direction orthogonal to the axial direction of the hollow portion 5.
a and 8b are installed, and the respective ducts 8a and 8b are connected to the discharge side and the suction side of the air conditioner 3 via pipes 9a and 9b. Each of the ducts 8a and 8b has a communication port 10
The air passages 7a and 10b communicate with the respective hollow portions 5a and 5b constituting the air passage 7 in series.

In the above configuration, when the air conditioner 3 is operated, the conditioned air flows from the discharge side pipe 9a to the duct 8a, and flows from the duct 8a to one end of the hollow portion 5a via the communication port 10a. Next, the conditioned air flows through the hollow portion 5a to the other end, flows into the other end of the hollow portion 5b through the communication port 6, and flows through the hollow portion 5b from the other end to one end. Next, the conditioned air flows into the duct 8b via the communication port 10b, and returns to the suction side of the air conditioner 3 via the pipe 9b. Thus, in the present invention, the circulating conditioned air does not pass through the living room.

In the above circulation, the conditioned air is supplied to the hollow portion 5.
The hollow slab 4 is heated or cooled when passing through the holes a and 5b. As shown in FIG. 1, radiation cooling and heating are performed using both the upper and lower surfaces of the hollow slab 4 as radiation heat transfer surfaces. Since the lower surface side of the hollow slab 4 corresponds to the ceiling of the living room 1 and the upper surface side corresponds to the floor of the living room on the upper floor, by applying the above configuration to each floor, the living room 1 on each floor has a floor and a ceiling. Hollow slab 4
Radiant cooling and heating can be performed using each of the surfaces as a radiant heat transfer surface.

In the above embodiment, both surfaces of the hollow slab 4 are radiant heat transfer surfaces. However, in another embodiment, that is, in a second embodiment, only one of the surfaces is a radiant heat transfer surface. can do. In this case, as shown in FIG. 4, unnecessary heat radiation from this surface can be prevented by installing the heat insulating material 11 on the surface of the hollow slab 4 opposite to the surface serving as the radiation heat transfer surface. . With such a configuration, in each living room 1, radiation cooling and heating can be performed from either the floor side or the ceiling side.

In another embodiment, that is, in a third embodiment shown in FIG. 5, a heat exchange unit 12 is formed in the air conditioner 3 and the outside air is suitable for air conditioning in the heat exchange unit 12. After heating or cooling to the temperature, the air can be supplied into the living room 1 and the air in the living room 1 can be discharged from a suitable place to the outside.

6 and 7 show a fourth embodiment of the radiant cooling / heating system of the present invention. FIG. 6 is a longitudinal section showing a certain floor portion of a building as in FIG. FIG.
FIG. 7 is a plan view. FIG. 6 is a sectional view taken along line CC of FIG. Reference numeral 1 denotes a living room, and 13 denotes a corridor. The ceiling C, the floor F, and the wall W are each formed of a hollow slab 4, and the hollow slab 4 has a large number of hollow portions 5 arranged in parallel. The hollow portion 5 of the hollow slab 4 of the ceiling C and the floor F is oriented in the left-right direction in FIG. 6 similarly to FIG. 1, and the hollow portion 5 of the hollow slab 4 of the wall W is It is oriented parallel to the hollow part 5 of the hollow slab 4 and therefore in the left-right direction in FIG. As shown in FIG. 6, the hollow portions 5 of the hollow slabs 4 of the ceiling C and the floor F communicate with each other by a communication port 6 for each adjacent pair at the end side of the hollow slab 4 opposite to the corridor 13. Therefore, each of the pair of hollow portions 5 (the pair of hollow portions is not shown in FIG.
This is the same configuration as. 1) constitutes a series of air passages 7 extending from one end to the other end of the corridor 13 as in FIG. As shown in FIG. 6, a pair of ducts 8a and 8b are provided below the hollow slab 4 of the ceiling C of the corridor 13 in a direction orthogonal to the axial direction of the hollow portion 5.
Each of the ducts 8a and 8b is connected to a discharge side and a suction side of an air conditioner (not shown) via a pipe or the like (not shown). The respective ducts 8a and 8b communicate with the respective hollow portions 5 forming the serial air passage 7 through the communication ports 10a and 10b. Similarly, as shown in FIG. 7, the hollow portion 5 of the hollow slab 4 of the wall W communicates with the adjacent pair of communication holes 6 on the end side of the hollow slab 4 opposite to the corridor 13. Therefore, each of the pair of hollow portions 5 constitutes a series of air passages 7 that extend from one end of the corridor 13 to the other end and turn back to return to one end.
Outside the living room 1, a pair of ducts 8 a and 8 b are installed in the hollow slab 4 of the wall W on the corridor 13 side in the vertical direction orthogonal to the axial direction of the hollow portion 5.
8b is an air conditioner (not shown) via a pipe or the like (not shown)

In the above configuration, when an air conditioner (not shown) installed at an appropriate position is operated, the conditioned air is supplied to the first air conditioner.
Is circulated and supplied to the pair of hollow portions 5 of the hollow slab 4 on the ceiling side with respect to the living room 1 through the ducts 8a and 8b by the same operation as that of the embodiment, so that the hollow slab 4 is heated or cooled, As shown in FIG. 6, radiation cooling and heating are performed using both the upper and lower surfaces of the hollow slab 4 as radiation heat transfer surfaces. Since the lower surface side of the hollow slab 4 corresponds to the ceiling of the living room 1 and the upper surface side corresponds to the floor of the living room on the upper floor, by applying the above configuration to each floor, the living room 1 on each floor has a floor and a ceiling. Radiation cooling and heating can be performed using each surface of the hollow slab 4 as a radiation heat transfer surface.

At the same time, in this embodiment, the conditioned air is circulated through ducts 8a and 8b to the air passage 7 formed by the pair of hollow portions 5 of the hollow slab 4 forming the wall W of the living room 1. Then, by heating or cooling the hollow slab 4, radiation cooling and heating are performed with both surfaces of the hollow slab 4 as radiation heat transfer surfaces as shown in FIG.

As described above, in the fourth embodiment, similarly to the above-described embodiment, the conditioned air circulating through the air passage 7 does not pass through the living room 1 and the wall W together with the ceiling C and the floor F is not circulated. Radiation cooling and heating can be performed by using both surfaces of the hollow slab 4 constituting a radiation heat transfer surface.

In the fourth embodiment, the second and third embodiments can be applied. In addition, the radiant cooling and heating by the hollow slab 4 of the ceiling C and the floor F, and the wall W
The radiant cooling and heating by the hollow slab 4 that constitutes the above may be configured to always operate simultaneously, or may be configured to be operable independently. In the fourth embodiment, the wall W
The hollow portion 5 of the hollow slab 4 is oriented in parallel with the hollow portion 5 of the hollow slab 4 of the ceiling C and the floor F. However, as shown in FIG. In this case, the circulation supply duct (not shown) faces in parallel with the hollow portion 5 of the hollow slab 4 of the ceiling C and the floor F.

Next, a specific example of the hollow portion 5 formed in the building structure 4 to be operated as an air passage in the present invention will be described. First, FIG. 9 to FIG. 15 show configuration examples of a hollow portion of a structure constituting a floor F (or a ceiling C) of a building. FIG. 9 shows a floor slab 10 as a structure of a building.
1 is a double slab structure formed of an upper slab 101a and a lower slab 101b separated by a beam 102, in which a space between the upper and lower slabs 101a and 101b is used as a hollow portion 5. Different from the ones shown in the figure, those that protrude downward are also included. FIG. 10 shows a case where the void slab 103 is used as a floor slab as a building structure, and the void portion 104 itself is replaced with the hollow portion 5.
The shape of the void portion 104 is appropriate. FIG. 11 shows an example in which the present invention is applied to a steel-framed building, and a concrete panel 108 in which a column 107 is attached above a concrete slab 106 installed above a steel beam 105.
A panel made of a material having a high specific heat such as that described above is mounted thereon to constitute the hollow portion 5 through which air can flow. Such a support 1
07 is attached to the concrete panel 108,
The present invention can also be applied to the case of an RC building. FIG.
2 is an example applied to an RC building. In this example, a panel made of a material having a high specific heat such as a concrete panel 111 as a floor finishing material is installed above the beam 110 of the inverted beam type floor slab 109. To form a hollow portion 5 through which air can flow. FIG. 13 shows an example in which the present invention is applied to an RC building.
The hollow portion 5 is formed by supporting a concrete panel 114 or a plate made of another material having a high specific heat at a distance from the housing. FIG. 14 shows another example in which the present invention is applied to a steel-framed building as in FIG. 11. Unlike FIG. 11, concrete panels are provided between the steel beams 115 below the concrete slab 116 installed above the steel beams 115. The hollow portion 5 is formed by supporting a plate made of a material having high specific heat or 117 or other material. In the above configuration, the floor F constituting the hollow portion 5
Upper and lower surfaces can be radiation heat transfer surfaces. on the other hand,
FIG. 15 shows a configuration in which the hollow portion 5 is formed by supporting a panel 118 of a heat insulating material instead of the concrete panel 114 of FIG. 13. In this case, the radiation heat transfer surface is only the upper surface of the floor F. To summarize the above examples, these are those in which the floor slab itself as the structure of the building has the hollow portion 5, or that the floor slab is attached and supported by a concrete panel or a plate material having a high specific heat. It constitutes the hollow portion 5. As described above, the plate and the like added to the structure are radiated from this surface by using a material having a high specific heat and a good heat conductivity, such as concrete or stone, as is common to the example of the wall portion described later. Although heat transfer is possible, if a material having a high heat insulating effect such as light-weight concrete or light-weight cellular concrete is used, radiant heat transfer from this surface can be prevented. Of course, these can be combined to form the hollow portion 5.

Next, FIGS. 16 to 19 show examples of the configuration of the hollow portion of the structure constituting the wall W of the building. First, FIG. 16 shows a case where a wall W as a structure of a building is composed of a wall portion 119 and a wall portion 120 which are integrated with a space therebetween, and a space formed therein is replaced with a hollow portion 5. It is used as FIG. 17 shows a case where the void W is used as the hollow portion 5 when the wall W is a void wall. FIG. 18 shows an example in which the present invention is applied to an RC building, in which a wall 123 is formed at an interval on one side of a wall 122, and these walls 122, 12 are provided between pillars 124.
The space formed between the three is used as the hollow portion 5, and the wall 122 is made of concrete or a plate made of a material having a high specific heat, and the wall 123 is made of a plate made of a material having an appropriate high specific heat. Make up. FIG. 19 shows an example in which the present invention is applied to a steel-framed building.
And the space 127 is supported at an interval, and the space formed therebetween is used as the hollow portion 5.
As in the case of No. 8, the wall 126 is made of concrete or a plate made of a material having a high specific heat, and the wall 127 is made of a plate made of a material having an appropriate high specific heat. In the above example in which the hollow portion 5 is formed in the wall W, similarly to the case of the floor W, in addition to the radiation heat transfer surfaces on both sides of the wall W, the radiation heat transfer surface is provided by installing a heat insulating material. On only one desired side.

In the present invention, in addition to the above-described floor F (or ceiling C) and wall W, columns, beams, or It can be configured in an appropriate part such as a foundation, and that part is
As long as it contributes to radiant cooling and heating in a room such as a living room, a radiant heat transfer surface may be configured in that part, and that part is
When it does not contribute to the indoor radiation cooling and heating, it can be used as a piping element constituting a circulation path of the conditioned air by installing a heat insulating material in that part to prevent heat radiation. That is, according to the present invention, as shown in the above-described embodiment, in addition to the configuration in which most of the surface of the structure forming the air passage 7 is used as a radiant heat transfer surface to the chamber, the air passage 7 is also used. Part of the surface of the structural body can be used as a heat transfer surface for radiation to the chamber.

In the present invention, the air passages 7 formed by the hollow portions 5 may be arranged in series or in parallel by connecting the adjacent hollow portions with the communicating portions, or the hollow portions may be partitioned by the partition plate. By forming a series air passage in the hollow portion, the length of the air passage can be appropriately adjusted, and by adjusting the air passage, the ratio of heat exchange between the conditioned air and the structure can be adjusted. it can. That is, FIG. 20 first shows the adjacent hollow portions 5a and 5b formed in the floor portion,
One example in which a communication port 129 is provided in the beam 128 to form a serial air passage 7, and a case in which a vertical partition plate 130 is provided in one hollow part 5 to partition the air path 7, 2 shows two examples in which the air passage 7 is formed. In this figure, these three examples are shown in the same drawing for the sake of convenience, but these examples are configured alone or in combination. In the drawings, (a) is a sectional view taken along the line AA of (b).

Next, FIG. 21 shows that one horizontal partition plate 131 is provided in the hollow portion 5 formed in the floor F of the configuration of FIG. This shows another example in which a series air passage 7 is configured to be reversed.
(b) is a sectional view taken along line BB of (a). In addition, by alternately installing a plurality of partition plates, the air passage 7 in which the air flow is reversed a plurality of times in the hollow portion 5 can be configured. In each of the above-described configurations, by providing the series air passages 7 as described above, both ends of each air passage 7 can be configured on one side of the structure as illustrated, The configuration of the piping system connected to these can be rationalized, and such a series air passage 7 increases the distance of the air passage 7, so that the heat between the conditioned air and the structure constituting the air passage 7 The exchange distance can be lengthened. Because of this, the configuration of the piping system,
The degree of freedom in design, such as setting of the heat exchange distance, is increased. The hollow portion 5 forming the air passage 7 in series as described above can be formed in any of the above-described portions in addition to the floor portion in this example.

On the other hand, in the above embodiment, the communication between the adjacent hollow portions 5 is performed by forming the communication port 6 between them, but in the embodiment shown in FIG. The communication between the hollow portions 5a and 5b is performed by a connection duct 132 provided outside, and the configuration of such communication is also appropriate. FIG. 22 corresponds to the configuration of FIG. 9, and FIG. 22B is a cross-sectional view taken along line DD of FIG.

[0027]

As described above, the present invention circulates and supplies conditioned air from an air conditioner to an air passage formed by a hollow portion formed in a structure of a building, and at least a part of the structure. The conditioned air that performs radiant cooling and heating and is circulated and supplied to the air passage does not pass through the room, and thus has the following effects. (1). Since it is radiant cooling and heating that does not use the conditioned air supplied into the room as a heat medium, the temperature distribution is uniform. (2). Since the air of cooling and heating does not directly hit the skin, the feeling of warming and cooling is good. (3). It is sanitary because it does not cause the dust or ticks in the room to be rolled up by the conditioned air, and is optimal for air conditioning in hospitals and the like. (4). Since the indoor air does not enter the air passage, it is possible to prevent germs and the like from propagating in the air passage, and to keep the room free of contamination. (5). The radiant heat transfer surface can be configured not only on either the floor or the ceiling, but also on both, so in this case, the radiation efficiency can be increased, as in the case where only the floor is configured. It is possible to prevent the radiation efficiency from lowering due to an object placed thereon. (6). It is not necessary to set the temperature of the conditioned air that flows through the air passage for radiation cooling and heating as a temperature that maintains the indoor environment, so that the temperature can be raised or lowered as appropriate to enhance the radiation heat transfer effect.
