Description

  The present invention relates to a radiant cooling / heating device for buildings, and more particularly to a radiant cooling / heating device and a dehumidifying / humidifying cooling / heating system using radiant heat.

  Air conditioners with built-in compressors are mainly used as conventional air conditioners for buildings. There are wall-mounted, floor-mounted, ceiling-suspended, ceiling-embedded, etc. air-conditioning outlets, and an outdoor unit with a built-in compressor, condenser, and fan is installed outside the building. The air-conditioning apparatus having this structure is called a heat pump system, and utilizes a characteristic that a medium is compressed to a high temperature and decompressed to a low temperature.

  Heat pump air conditioners are used in general home air conditioners and small to medium-sized buildings, and multi-air conditioners that centrally control indoor units are used in medium and large buildings. Other cooling and heating facilities for large-scale buildings include electric refrigerators, electric boilers, boilers using fossil fuels, direct-fired hot / cold water generators, etc. Is blowing. Furthermore, the use of natural energy such as solar heat, geothermal heat, and groundwater, which places importance on environmental problems, has been developed.

  Of these, heat pump type air conditioners and fan coil units are mainly used. This is a method in which the room temperature is directly handled by cool / warm air, and the energy source is a heat source device installed outside the room. The heat source temperature of the medium or cold / hot water is 5 to 7 ° C. during cooling, 50 to 60 ° C. during heating, and the room temperature is controlled to about 26 to 28 ° C. during cooling and 20 to 22 ° C. during heating. However, the current research theme is how to increase COP (Coefficient Of Performance) for simultaneous processing of temperature (sensible heat) and humidity (latent heat).

  Furthermore, when sending cold / hot air directly, the indoor temperature distribution is biased depending on the wind force, wind direction, etc. Furthermore, in Japan, where there are four seasons with high temperature and high humidity, the correlation between temperature (sensible heat) and humidity (latent heat) provides a comfortable feeling for people. There will be considerable variation. In addition, when cold and warm air directly hits the human body due to wind power, it has adverse effects on health such as limb cooling.

  In consideration of such effects, air conditioning equipment for the purpose of radiant cooling and heating has been developed. A typical example is the ondol that has been used in Korea since ancient times. This is because the flue gas used for cooking and the like was provided with a duct on the floor to warm the whole floor, but at present, a cold / hot water circulating ondol system with a pipe installed under the floor has become mainstream due to the spread of condominiums and the like. In Japan, a system for radiant cooling and heating has been developed in which water pipes are buried in ceilings and walls, and cold and hot water is circulated therein.

  However, even if the room temperature is controlled by radiant cooling and heating, when the humidity is high, it does not feel appropriate unless the cooling capacity is increased, and when the humidity is low, the humidity decreases further when the temperature is increased. There was a problem of adverse effects on. In addition, when the cooling capacity is increased with high humidity, condensation may occur in the heat source part (water pipes, etc.), which may damage the ceiling, wall and floor materials, and may corrode water pipes. There was also concern about water leakage due to corrosion of water piping. In general households, humidifiers and dehumidifiers are used together to control humidity.

  Under such circumstances, the idea of controlling temperature and humidity separately has appeared. Development of a desiccant method (method using a dehumidifying material) that can control humidity has developed a product that can control the adsorption and release of moisture during intake and exhaust. Thus, the humidity can be controlled, and the dehumidified / humidified COP can be increased to 4.0 or more. Therefore, it is possible to examine the rest by focusing only on the temperature.

  In view of this, a radiant cooling and heating system corresponding to temperature has been devised. For example, as shown in FIGS. 17 and 18, the radiant cooling and heating system disclosed in Patent Document 1 includes a hollow portion 805 in a building structure (concrete slab) 804 to form an air passage 807, and an air conditioner 803. The conditioned air is circulated and supplied, and at least a part of the structure constituting the air passage 807 is used as a radiation heat transfer surface to the living room 801. In addition, as shown in FIG. 19, the radiation cooling and heating system disclosed in Patent Document 2 is provided with a radiation panel 911 inside a horizontal structure (concrete slab) that partitions the upper and lower floors of a building, and is heated or cooled by a heat source. A heat medium pipe 912 through which a heat medium (for example, water, oil, refrigerant, etc.) flows is partitioned by a heat insulating material 913, and a radiation panel 911 having a first heat conductor 914 on the upper surface and a second heat conductor 915 on the lower surface. A radiant cooling / heating system that performs cooling / heating by radiant heat has been developed.

Japanese Patent Laid-Open No. 10-311565 JP 2009-222294 A

  Each of the above technologies is a radiant cooling / heating system that uses a heat medium (air, water, oil, refrigerant, etc.) inside a concrete slab of a building. It is configured to store heat and perform radiant cooling and heating. In this configuration, it is necessary to pipe (for example, embed) a heat medium in the concrete slab, which requires considerable cost and labor at the time of construction. In addition, considerable time and energy are required to store heat in the concrete slab even during operation. For this reason, it is necessary to store heat to the concrete slab for a long time using nighttime electric power or the like, which is not preferable in terms of quick response and energy efficiency. Furthermore, in Japan, an earthquake-prone country, the structure of the building is distorted in the event of an earthquake, and heat medium (air) leaks due to cracks in the concrete slab, or damage to the hollow pipe (water) , Oil, refrigerant, etc.) may also flow out. For example, if a heat medium such as water leaks from a pipe provided on the ceiling, there is a possibility that a rain leakage state may occur. In addition, in order to repair the air conditioner, it is necessary to repair the concrete slab of the building itself, and further, it is difficult to access even during normal maintenance work, and there is a problem that workability is extremely poor.

  The present invention has been made in view of such a background. A main object of the present invention is to provide a building air conditioning system that is excellent in energy efficiency and easy to construct and maintain, and particularly to provide a radiant cooling / heating device and a dehumidifying / humidifying cooling / heating system using radiant heat.

Means for Solving the Problems and Effects of the Invention

  In order to achieve the above object, according to the first aspect of the present invention, there is provided a radiant cooling / heating device 100 capable of cooling and heating a cooling / heating target area using radiant heat, the radiating duct 10 being arranged in the cooling / heating target area. And the air conditioning means 200 for blowing the temperature-controlled air whose temperature is adjusted by the heat source to the radiation duct 10 and the radiation duct 10 and the air-conditioning means 200 are connected in an airtight state to circulate the temperature-controlled air. In the apparatus provided with the heat insulating air-conditioning pipe 20, heat transfer that absorbs heat from the temperature-controlled air and transfers heat to the radiation duct 10 is arranged in the radiation duct 10 in a posture that inhibits circulation of the temperature-controlled air. A member 15 is provided. Thus, the temperature-controlled air is thermally adsorbed by the plurality of heat transfer members in the radiation duct, and the heat source is efficiently conducted. Furthermore, since the circulation air-conditioning circuit that is closed and airtight is formed, dust does not accumulate in the air-conditioning means, and the filter does not need to be cleaned. Further, since no cool / warm air is generated in the room, it is possible to prevent the dust that is the cause of the house dust from diffusing, and to reduce the uneven temperature distribution. Furthermore, since a circulation air-conditioning circuit is formed, the temperature difference between the temperature-controlled air blown out from the air-conditioning means outlet and the heat release air returned is small because the temperature is not exchanged with the outside air. The load on the means can be reduced and the COP can be increased.

  Moreover, according to the radiation cooling and heating apparatus 100 which concerns on the 2nd side surface of this invention, the radiation duct 10 is excellent in the thermal conductivity installed in the box-shaped duct 11 which has the input port 18 and the output port 19, and the heat radiating surface side. And a heat insulating material 13 attached to the side wall surface excluding the radiation panel 12. Thereby, a regular box-shaped duct can be used, and phenol foam having a low thermal conductivity can be used. As the material of the radiant panel, a metal such as aluminum, copper, iron or the like, or an alloy having excellent thermal conductivity is suitable.

  Furthermore, according to the radiant cooling and heating apparatus 100 according to the third aspect of the present invention, the radiant duct 10 has a radiant panel 12 having excellent thermal conductivity, and a side wall surface having an input port 18 and an output port 19. The heat insulating member 14 is fitted and formed. As a result, the number of constituent members constituting the radiation duct can be reduced, and the work efficiency can be increased because the heat transfer member can be fitted and formed on the radiation panel after being attached to the radiation panel. Furthermore, this makes it possible to adapt to the air conditioning target area where the radiation panel is installed, and to adapt to the installation conditions. A material of the radiation panel that can be used here is a metal such as aluminum, copper, iron, or an alloy, and has excellent thermal conductivity.

  Furthermore, according to the radiant cooling and heating apparatus 100 according to the fourth aspect of the present invention, the heat transfer member 15 is substantially disposed on the heat connection surface 16B thermally coupled to the radiant panel 12 and the heat radiating surface inside the radiant duct 10. As a rectangular plate installed vertically, it has a heat absorption surface 16A. The heat absorption surface 16A is approximately the same as the internal height with respect to the radiation duct 10, and the width is about ½ of the input port 18 surface. 3/4, the direction is substantially parallel to the wall surface of the input port 18, and a plurality of heat transfer members 15 are installed in a staggered manner from the input port 18 to the output port 19 of the radiation duct 10 at substantially equal intervals. The wind flow in the ventilation space in the radiation duct 10 can be meandered. As a result, the air flow of the temperature-controlled air can be absorbed by the heat absorption surfaces of the heat transfer members and efficiently conducted to the radiation panel that is thermally coupled to the heat connection surfaces. In addition, a plurality of heat transfer members can be arranged in a staggered manner, temperature-controlled air can be retained on each heat absorption surface to sufficiently exchange heat with the radiant panel, and further radiant heat can be propagated indoors. Here, although the direction of the heat absorption surface of the heat transfer member is substantially parallel to the input port wall surface, the direction is not limited to this and may be substantially inclined with respect to the input port wall surface.

  Furthermore, according to the radiation cooling and heating apparatus 100 according to the fifth aspect of the present invention, the heat insulating air conditioning pipe 20 is connected to the air outlet of the air conditioning means 200 and is connected to the input port 18 of the radiation duct 10. A plurality of insulated air pipes 20 and radiation ducts 10 can be further connected in series to the output port 19 to expand the range of the air conditioning target area. Thereby, the heating and cooling radiation range can be widened by connecting the radiation ducts in series according to the size of the room.

  Furthermore, according to the radiant cooling and heating apparatus 100 according to the sixth aspect of the present invention, the heat insulating air conditioning pipe 20 is connected to the air outlet of the air conditioning means 200 and branches in parallel. The volume damper 30 is installed, the output of the volume damper 30 is connected to the input port 18 of the radiation duct 10, and the adiabatic air pipe 20 and the radiation duct 10 are further connected in series to the output port 19 of the plurality of radiation ducts 10. The range of the air conditioning target area can be expanded. Thus, the radiation range can be selected by connecting the radiation ducts in parallel and in series according to the size of the room, and when connected in parallel, the flow rate adjustment of the temperature-controlled air to each radiation duct is performed by the volume damper Thus, the temperature deviation in the room can be adjusted.

  Furthermore, according to the radiation cooling and heating apparatus 100 according to the seventh aspect of the present invention, the radiation duct 10 can be disposed on the ceiling CE surface.

  Furthermore, according to the radiation cooling / heating apparatus 100 according to the eighth aspect of the present invention, the radiation duct 10 can be disposed on the wall WA surface.

  Furthermore, according to the radiation cooling and heating apparatus 100 according to the ninth aspect of the present invention, the radiation duct 10 can be disposed on the floor FL surface. Without being limited to these installation places, it is also possible to provide on a plurality of surfaces such as a floor surface, a ceiling surface, and a wall surface.

  Furthermore, according to the radiant cooling / heating device 100 according to the tenth aspect of the present invention, a drain pipe for drainage is not required. This allows the air inside to be dried at the time of forming a closed circulation air-conditioning circuit during installation. As a result, the temperature-controlled air that circulates in the radiant cooling and heating system during use is isolated from the outside air, so moisture can be prevented from entering the temperature-controlled air and condensation due to temperature changes can be prevented. Since it is not necessary to install a drain pipe, the construction and installation space of the drain pipe can be reduced.

  Furthermore, according to the dehumidifying / humidifying heating / cooling system according to the eleventh aspect of the present invention, the dehumidifying / humidifying device 300 capable of controlling latent heat, the dehumidifying / humidifying device 300, and the radiant cooling / heating device 100 are linked to each other. And a controller 250 capable of controlling the temperature and humidity. As a result, if the cooling capacity is not increased when the humidity is high, it will not feel the right temperature, and if the humidity is low, the temperature will further decrease and the problem of adversely affecting the respiratory organs of the human body will be avoided. can do. Furthermore, latent heat and sensible heat can be monitored simultaneously, the temperature and humidity can be adjusted by the controller, and further energy saving can be realized.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. However, the embodiment shown below exemplifies a radiant cooling / heating apparatus and a dehumidifying / humidifying cooling / heating system using radiant heat for embodying the technical idea of the present invention, and the present invention is radiant cooling / heating using radiant heat. The equipment and dehumidifying / humidifying / heating systems are not specified as follows. Further, the present specification by no means specifies the members shown in the claims to the members of the embodiments. In particular, the dimensions, materials, shapes, relative arrangements, and the like of the component parts described in the embodiments are not intended to limit the scope of the present invention unless otherwise specified, and are merely explanations. It is just an example. Note that the size, positional relationship, and the like of the members shown in each drawing may be exaggerated for clarity of explanation. Furthermore, in the following description, the same name and symbol indicate the same or the same members, and detailed description thereof will be omitted as appropriate. Furthermore, each element constituting the present invention may be configured such that a plurality of elements are constituted by the same member and the plurality of elements are shared by one member, and conversely, the function of one member is constituted by a plurality of members. It can also be realized by sharing.

A radiant cooling and heating apparatus 100 according to an embodiment of the present invention will be described with reference to FIGS. FIG. 1 shows a schematic configuration diagram of a radiant cooling and heating apparatus 100. Temperature-controlled air from the air outlet of the air conditioning means 200 is supplied to the radiation duct 10 through the heat insulating air conditioning pipe 20 in an airtight state. Furthermore, a circulation air-conditioning circuit is constructed in which the heat release air returns from the radiation duct 10 to the air inlet of the air-conditioning means 200 through the heat-insulating air-conditioning pipe 20 in an airtight state. The air-conditioning means 200 used here is desirably a high sensible heat type air conditioning air conditioner. In addition, since a closed structure that does not allow outside air to enter is eliminated, entry of dust and moisture from the outside is eliminated, so that clogging of the filter inside the air-conditioning means 200 and contamination of the heat conduction fins are suppressed, and maintenance is performed. Free and close to the environment can be realized. Moreover, COP4.5 or more is realizable by combining a desiccant-type dehumidifier with a high sensible heat type air conditioning unit.
(Radiation duct)

  Furthermore, as an example of the structure of the radiation duct 10 used in FIG. 1, as shown in the vertical sectional view of the radiation duct 10 in FIG. It is possible to have a structure in which the outer peripheral surface is covered and covered with the heat insulating material 13 and integrally formed. The duct 11 used here can be produced inexpensively by using a duct such as a general galvanized steel sheet. Moreover, although the heat insulating material 13 utilizes the phenol foam with low heat conductivity, it can also be made not only into this but a chemical fiber type or a mineral fiber type. Furthermore, although the radiation panel 12 is made of aluminum having excellent thermal conductivity, it is not limited to this and may be made of a metal such as copper having excellent thermal conductivity. Thereby, the release of heat outside the radiant panel 12 can be blocked, and the radiant heat can be efficiently propagated into the room 1 only from the side of the radiant panel 12 in contact with the room 1.

  As a further example of the structure of the radiation duct 10, as shown in the vertical sectional view of the radiation duct 10 in FIG. 3, the radiation panel 12 and a heat insulating member 14 formed in a box shape are fitted and formed with an adhesive or the like. It can also be. Here, the heat insulating member 14 to be used is a foamed plastic type such as extruded polystyrene foam, and the radiant panel 12 uses aluminum having excellent thermal conductivity, but other metals such as copper and iron are used. Or an alloy or the like. Thereby, the radiation duct 10 can reduce the number of processes and the number of parts at the time of manufacture, and can further reduce the weight, so that the weight influence on the building body can be reduced.

  Further, the vertical sectional view of the radiation duct 10 shown in FIG. 4 is a modification of the example shown in FIG. 2, and the radiation panel 12 and the duct 11 formed in a box shape are joined by an adhesive or the like, and the radiation panel 12 is joined. The outer peripheral surface of the duct 11 except for can be covered with a heat insulating material 13 so as to be integrally formed. This method is also inexpensive, and the heat transfer member 15 described later can be attached before joining the radiation panel 12 and the duct, facilitating the production of the radiation duct. Each experiment is carried out by this method, and the subsequent drawings are also explained by this processing method.

  FIG. 5 is a perspective view of the radiation duct 10 modeled on FIG. 4, and connection tubes 17 for connecting the heat-insulating air-conditioning pipes 20 are provided at two locations of the input port 18 and the output port 19. Thereby, the connection with the heat insulation air-conditioning piping 20 in an installation site can be implemented efficiently. Further, the connection cylinder 17 for connecting the heat-insulating air conditioning pipe 20 is not provided, but the heat insulating air-conditioning pipe 20 is directly provided with an opening hole in the wall surface of the radiation duct 10 and inserted there, and the inserted periphery is sealed, thereby the radiation duct 10. The processing of the heat insulating member 14 can be simplified, and the weight can be further reduced.

Here, the dimension of the radiation duct 10 can be determined by the size of the contact surface of the air conditioning target area to be installed. In the embodiment, the experiment was performed by setting the width W of the radiation duct 10 to 450 mm, the height H to 200 mm, and the length L to 1800 mm, but the present invention is not limited to this.
(Heat transfer member)

  In this radiation duct 10, the heat transfer member 15 as shown in FIGS. 6 and 7 has an L-shaped process having a heat absorption surface 16A and a heat connection surface 16B, and the heat absorption surface 16A is the radiation panel 12. A plurality of devices are installed substantially vertically. Further, the heat transfer member 15 is fixed by an adhesive or spot welding so that the heat connection surface 16B and the radiation panel 12 are thermally bonded.

  Further, the heat absorption surface 16A of the heat transfer member 15 used here has a width of about 1/2 to 3/4 of the width W of the radiation duct 10 and a height substantially equal to the inner height of the radiation duct 10. Say it. Furthermore, although the experiment was carried out with the interval between the heat transfer members 15 being 150 to 250 mm, it is not limited to this interval. Thereby, the heat of the air-conditioned air can be exchanged from the heat transfer member 15 to the radiant panel 12, and the radiant heat can be efficiently propagated from the radiant panel 12 to one space in the room.

  Further, although aluminum having excellent thermal conductivity is used as the material of the heat transfer member 15, other metal such as copper, iron, or alloy can be used.

  FIG. 8 is a horizontal sectional view taken along line BB of Example 1 of the radiation duct 10 of FIG. The heat transfer members 15 are installed in a zigzag shape so that the temperature-controlled air does not flow linearly from the input port 18 to the output port 19 of the radiation duct 10, and the direction of the heat absorption surface 16 </ b> A is substantially parallel to the surface of the input port 18. It is installed. Thus, the temperature-controlled air blown from the input port 18 is sent to the output port 19 while meandering between the heat transfer members 15 while being in thermal contact with the heat absorption surface 16A of the heat transfer member 15. When it comes into contact with the heat member 15, it absorbs heat and can be efficiently transferred to the radiation panel 12.

  FIG. 9 shows a horizontal sectional view taken along line BB of Example 2 of the radiation duct 10 of FIG. 5 as still another installation method. The heat transfer members 15 are arranged in a staggered manner so that the temperature-controlled air does not flow linearly from the input port 18 to the output port 19 of the radiation duct 10. Further, the heat transfer member 15 is provided with an inclination in the wall surface direction from the inside of the radiation duct 10 toward the output port 19 in order from the input port 18 to the heat absorption surface 16A, and the next heat transfer member 15 is directed from the inner side to the opposite side surface. It is installed alternately.

  Similarly, as another installation method, FIG. 10 shows a horizontal sectional view taken along line BB of Example 3 of the radiation duct 10 of FIG. The heat transfer members 15 are arranged in a staggered manner so that the temperature-controlled air does not flow linearly from the input port 18 to the output port 19 of the radiation duct 10. Further, the heat transfer member 15 is provided with an inclination in the wall surface direction from the inner side of the radiation duct 10 toward the input port 18 in order from the output port 19 to the heat absorption surface 15A, and the next heat transfer member 15 is directed from the inner side to the opposite side surface. It is installed alternately.

As described above, the heat transfer member 15 inside the radiation duct 10 may be installed by heat-absorbing the temperature-controlled air at the heat absorption surface 16A of the heat transfer member 15 and exchanging heat from the heat contact surface 16B to the radiation panel 12. It is not limited to the example of 6 to FIG. Furthermore, although the heat absorbing surface 16A of the heat transfer member 15 was tested as a rectangle, any shape that can retain the temperature-controlled air and a shape that can conduct heat of the temperature-controlled air, for example, a curved surface, a bent surface, and a rod shape. It can also be set as a shape etc., and is not limited. Thereby, the airflow of temperature-controlled air can be retained in each heat transfer member 15, the plurality of heat transfer members 15 can sufficiently exchange heat, and further radiant heat can be propagated into the room 1.
(Schematic configuration diagram)

  Here, a first configuration example of the radiant cooling and heating apparatus 100 will be described with reference to FIG. First, the blow-out box 22 and the heat-insulated air-conditioning pipe 20 are connected in order through the heat-insulating duct 21 from the air outlet of the air-conditioning means 200. Next, the adiabatic air conditioning pipes 20 are connected to the input port 18 of the radiation duct 10, and then a plurality of the adiabatic air conditioning pipes 20 and the respective radiation ducts 10 are connected in series. Further, the heat insulating air conditioning pipe 20, the blowing box 23, and the heat insulating duct 21 are connected in order from the terminal radiation duct 10 to constitute a circulation air conditioning circuit that returns to the blowing port of the air conditioning means 200.

  Here, in this first configuration example, six radiation ducts 10 are connected in series. However, the number is not limited to this number, and the number of radiation ducts 10 connected in series depending on the radiation range to the air conditioning target area. Can be selected.

  Furthermore, the 2nd structural example of the radiation cooling / heating apparatus 100 is demonstrated along FIG. First, the blow-out box 22 and the heat-insulated air-conditioning pipe 20 are connected in order through the heat-insulating duct 21 from the air outlet of the air-conditioning means 200. Next, the adiabatic air conditioning pipe 20 is branched in three directions to be in parallel, and a volume damper 30 is connected to each of the branched adiabatic air conditioning pipes 20. Furthermore, each radiation duct 10 is connected to each volume damper 30, and then each heat insulation air-conditioning pipe 20 and each radiation duct 10 are connected in series in the order. Furthermore, each heat insulation air-conditioning pipe 20 is connected to each radiation duct 10 arranged in parallel, and they are connected to one heat insulation air-conditioning pipe 20 and connected to the heat insulation duct 21 via the blowing box 23, and the air-conditioning means 200. Return connection to the inlet.

  These connection portions are airtightly connected, and the air flow of the temperature-controlled air is in the order of the air conditioning means 200, the blowing box 22, the heat insulating air conditioning pipe 20, the volume damper 30, the radiation duct 10, the heat insulating air conditioning pipe 20, and the blowing box 23. The circulation air-conditioning circuit which finally flows back to the air-conditioning means 200 is configured.

  Furthermore, in this second configuration example, three radiation ducts 10 are connected in parallel, and a total of six radiation ducts 10 are connected in series. However, depending on the radiation range to the air conditioning target area, the radiation ducts are connected. The number of 10 is not limited. Thereby, the radiation range to the air conditioning target area can be selected by increasing the number of radiation ducts 10 connected in parallel and in series in accordance with the size of the room 1.

  Furthermore, a volume damper 30 is connected to the front stage of the radiation ducts 10 connected in parallel, and the volume damper 30 adjusts the flow rate of the temperature-controlled air to the radiation ducts 10 connected in parallel. The temperature deviation can be adjusted.

  Furthermore, in both the first and second configuration examples, the circulation air conditioning circuit is installed with the internal air in a dry state. As a result, the temperature-controlled air that circulates in an airtight state has no contact with outside air, prevents dust and moisture from entering the circulating air-conditioning circuit, and prevents contamination of the filters and heat conduction fins inside the air-conditioning means 200. Can be obtained and cleaning maintenance can be reduced. Furthermore, since the temperature-controlled air is dried and moisture is not mixed, it is not necessary to install a drain pipe for drainage in the air-conditioning means 200. Therefore, the construction and installation space of the drain pipe can be reduced.

Furthermore, since this circulation air-conditioning circuit is formed, the heat exchange with the outside air is not performed. Therefore, since the temperature difference between the temperature-controlled air blown out from the air outlet of the air-conditioning means 200 and the heat release air returned to the air inlet is small, the operating efficiency of the air-conditioning means 200 can be lowered, and the COP Can be made 4.5 or more. For example, during cooling, the heat release air returns to the air conditioning means 200 at a temperature lower than the outside air temperature, and during heating, the heat release air returns to the air conditioning means 200 at a temperature higher than the outside air temperature. The energy saving effect can be enhanced.
(Example)

  This will be described with reference to a sectional view of installation according to the first embodiment shown in FIG. This sectional view is an embodiment in which the radiant cooling and heating device 100 is installed in the ceiling CE space. The radiation panel 12 of the radiation duct 10 combined with the ceiling CE surface is installed in contact with the room 1, and the air conditioning means 200 is installed on the back surface of the ceiling CE. Thereby, it propagates to the room 1 as radiant heat from the radiation panel 12 having the ceiling CE surface, and the entire room 1 can be set to a uniform set temperature. Here, since the radiation panel 12 combined with the ceiling CE surface is surface-treated in accordance with other ceiling material colors, there is no sense of incongruity.

  Furthermore, it demonstrates along the installation sectional drawing which concerns on Example 2 of FIG.

In this embodiment, the air conditioner 200 is installed on the back surface of the ceiling CE. However, if there is a space that can be installed on the back surface such as the wall WA or the floor FL, it can be installed.

  In addition to the embodiments shown in FIGS. 13 to 15, although not shown, the radiation duct 10 can be installed on two or three surfaces of the ceiling CE surface, the wall WA surface, and the floor FL surface. For example, a structure in which the adiabatic air pipe 20 is switched so that cooling is performed by radiant heat from the radiation duct 10 installed on the ceiling CE surface in summer and heating is performed by radiant heat from the radiation duct 10 installed on the floor FL surface in winter. You can also. Thereby, the room 1 can be efficiently cooled and heated by utilizing the heat conduction characteristics of air.

  Furthermore, FIG. 16 has shown the installation sectional view which shows the dehumidification / humidification cooling / heating system which concerns on embodiment. This dehumidifying / humidifying cooling / heating system is manifested by linking the air-conditioning means 200 used in the radiant cooling / heating apparatus 100 using radiant heat and the dehumidifying / humidifying device 300 capable of controlling the potential humidity with a connection cable 260. The temperature and potential humidity can be monitored simultaneously and adjusted by the controller 250. As a result, if the cooling capacity is not increased when the humidity is high, it will not feel the right temperature, and if the humidity is low, the temperature will further decrease and the problem of adversely affecting the respiratory organs of the human body will be avoided. It is possible to achieve high COP and energy saving.

  The air-conditioning means 200 used here is a high sensible heat type air conditioner, and the dehumidifier / humidifier 300 uses a desiccant dehumidifier / humidifier, so that the COP can be 4.5 or more and energy saving can be realized. Because it is possible to control the latent and manifestation in the room at the same time, it is possible to build a human-friendly system.
