Description

  The present invention relates to an air conditioning system, and more particularly to a radiant air conditioning system.

  In recent years, a radiant cooling and heating system has attracted attention as a cooling and heating system that achieves both energy saving and comfort. The radiant cooling and heating system is a system that cools (warms) a radiant panel installed on a ceiling surface or the like, and cools and heats an air-conditioning target room using radiant heat from the radiant panel. On the other hand, the heat load of a building is generally larger in the outer wall zone (perimeter zone) than in the inner zone (interior zone). As a radiant cooling and heating system that takes these characteristics into consideration, the interior zone has a large number of radiant panels that have pipes for water passage inside the ceiling and radiant cooling by heat exchange of the water that has passed through the pipes. There is one that performs heating and cooling with a forced convection type air conditioner using a blower (for example, see Patent Document 1) for the perimeter zone.

Japanese Patent Laying-Open No. 2005-121280 (paragraph 0007, FIG. 3, etc.)

  However, if the perimeter zone is cooled and heated by the forced convection method, an appropriate building heat load can be processed, but on the other hand, conveyance power for forced convection is required.

  An object of this invention is to provide the air conditioning system which improves the thermal environment of a perimeter zone, suppressing energy consumption in view of the above-mentioned subject.

  In order to achieve the above object, the cooling / heating system according to the first aspect of the present invention includes, for example, a perimeter zone Zp of a cooling / heating target room R having a window glass WG on the side wall SW adjacent to the outdoor EX as shown in FIG. A ceiling temperature change device 11 that changes the temperature of the ceiling Cp of the ceiling to a temperature different from the temperature of the surrounding air; and a gap S between the window glass WG so as to cover the window glass WG in the air conditioning target room R; Provided vertically below the ceiling Cpp of the perimeter zone Zp, the temperature of which is changed by the ceiling temperature changer 11, and an openable / closable shielding member 21 that shields the solar radiation that passes through the window glass WG and enters the air conditioning target room R. The shielding member 21 is attached to the ceiling Cpp of the perimeter zone Zp with an opening having a predetermined distance Lh in the height direction immediately below the ceiling Cpp of the perimeter zone Zp. . Here, the position immediately below the ceiling of the perimeter zone is a position that is close enough to allow heat exchange with the ceiling of the perimeter zone whose temperature is changed by the ceiling temperature changer.

  With this configuration, the shield member is attached to the ceiling of the perimeter zone so that an opening having a predetermined height is formed immediately below the ceiling of the perimeter zone so that air can flow through the shield member. During cooling, the air that is heated and raised between the window glass and the shielding member is cooled by the ceiling of the perimeter zone and becomes a downward flow along the shielding member on the indoor side. It is possible to improve the cooling effect by suppressing the temperature rise of the shielding member, and the perimeter before the downdraft generated on the window glass surface cooled by the outside air becomes this downdraft. Since it is warmed by the ceiling of the zone, the temperature drop of the downdraft is suppressed and the cold draft can be reduced.

  Moreover, as shown in FIG.1 and FIG.2, for example, in the air conditioning system which concerns on the said 1st aspect of the said invention, the ceiling Cp of a perimeter zone is the window glass WG. The outdoor-side ceiling Cpp which is a part of the side is recessed upward so as to accommodate a part of the shielding member 21, and the indoor-side ceiling Cpc which is the remaining part on the opposite side to the window glass WG side is the interior zone Zc of the target room R Both the outdoor-side ceiling Cpp and the indoor-side ceiling Cpc are configured such that the temperature is changed by the ceiling temperature changer 11.

  If comprised in this way, since the temperature of air is changed with an indoor side ceiling even when the shielding member is open, the temperature rise inhibitory effect of a shielding member and a cold draft reduction effect can be maintained.

  Moreover, the air conditioning system which concerns on the 3rd aspect of this invention is the length corresponding to the predetermined distance Lh in the air conditioning system which concerns on the said 1st aspect or this 2nd aspect of this invention, for example, as shown in FIG. The spacer 25 is a spacer 25 that connects the ceiling Cpp of the perimeter zone Zp whose temperature is changed by the ceiling temperature change device 11 and the shielding member 21.

  If comprised in this way, the opening of a predetermined distance can be reliably formed between the ceiling of a perimeter zone, and a shielding member. In addition, when the spacer is formed of iron or a material having a higher thermal conductivity than iron, the heat of the ceiling of the perimeter zone (including cold heat) can be transmitted to the shielding member, and the temperature rise of the shielding member can be suppressed. The effect and the cold draft reduction effect can be improved.

  Moreover, the air conditioning system which concerns on the 4th aspect of this invention is the object of air conditioning in the air conditioning system which concerns on any one aspect of the said 1st aspect thru | or 3rd aspect of this invention, for example, as shown in FIG. A radiant panel 16 provided on the ceiling Cc of the interior zone of the room R, the radiant panel 16 having a temperature changed by the heat medium CH; after the ceiling temperature change device 11 exchanges heat with the radiant panel 16 The temperature of the ceiling Cp of the perimeter zone is changed by the heat medium CH.

  With this configuration, after the heat held by the heat medium is used for the building heat load processing of the interior zone, it is used for the building heat load processing of the perimeter zone where the building heat load is larger. Of this, the amount of heat available for air conditioning can be increased. In this specification, the “building heat load” means a temperature difference from the outside air excluding a heat load based on a heat generation factor (for example, a human body, a lighting fixture, other electrical equipment, etc.) existing in the air conditioning target room. It shall be used as a word meaning the heat load caused by the structure of the building due to solar radiation.

  Moreover, the shielding member accommodation box which concerns on the 5th aspect of this invention is 50 used for the air conditioning system which concerns on the said 2nd aspect of this invention, as shown, for example to Fig.4 (a); Is a hexahedron-shaped box 51 having an opening 51h, which accommodates at least a part of the shielding member 21 and constitutes the outdoor-side ceiling Cpp; and a perimeter of the air conditioning target room with the box 51 facing the opening 51h downward Attached to the bottom surface 51b facing the opening 51h when attached to the zone and the side surface 51s on the interior zone side between the opening 51h and the bottom surface 51b, the temperature of the outdoor side ceiling Cpp is different from the temperature of the surrounding air. And radiating panels 12 and 13 to be changed into

  If comprised in this way, workability can be improved.

  According to the present invention, since the shielding member is attached to the ceiling of the perimeter zone with an opening having a predetermined height formed immediately below the ceiling of the perimeter zone, air can flow through the shielding member. During cooling, the air that is heated and raised between the window glass and the shielding member is cooled by the ceiling of the perimeter zone and becomes a downward flow along the shielding member on the indoor side. It is possible to improve the cooling effect by suppressing the temperature rise of the shielding member, and the perimeter before the downdraft generated on the window glass surface cooled by the outside air becomes this downdraft. Since it is warmed by the ceiling of the zone, the temperature drop of the downdraft is suppressed and the cold draft can be reduced.

It is a figure explaining the air-conditioning system concerning an embodiment of the invention. (A) is side surface sectional drawing around the perimeter zone, (b) is a front view around the window glass of the perimeter zone. It is side surface sectional drawing which shows the periphery of the perimeter zone of the state which has opened the shielding member of the air conditioning system which concerns on embodiment of this invention. It is a front view around the window glass of the perimeter zone which shows the modification of the air conditioning system which concerns on embodiment of this invention. It is a figure which shows the modification of the installation aspect of a perimeter radiation | emission panel. (A) is a partial side sectional view around the outdoor-side ceiling, (b) is a perspective view of a radiating panel used in this modification, and (c) is a partial side view of another form of radiating panel used in this modification. It is.

  Embodiments of the present invention will be described below with reference to the drawings. In the drawings, the same or similar members are denoted by the same or similar reference numerals, and redundant description is omitted.

  First, referring to FIG. 1, an air conditioning system 1 according to an embodiment of the present invention will be described. FIG. 1 is a diagram for explaining an air conditioning system 1. FIG. 1A is a side sectional view around a perimeter zone Zp, and FIG. 1B is a front view around a window glass WG in the perimeter zone Zp. The air-conditioning system 1 is a system installed in an air-conditioning room R as a room to be air-conditioned or air-conditioned, a perimeter radiating panel 11 as a ceiling temperature change device, a blind 21 as a shielding member, A spacer 25 is provided to maintain a predetermined distance Lh between the blind 21 and the ceiling Cp.

  The air conditioning room R is partitioned from the outdoor EX by the side wall SW. The side wall SW constitutes the outer wall of the building and is provided with a window glass WG. By providing the window glass WG, solar radiation can be taken into the air conditioning room R. The air conditioning room R can be conceptually distinguished into a perimeter zone Zp and an interior zone Zc. The perimeter zone Zp is an area adjacent to the side wall SW, is easily affected by solar radiation, and has a relatively large building heat load. The interior zone Zc is an area inside the heating / cooling room R that is separated from the side wall SW with the perimeter zone Zp interposed between the interior zone Zc and the area where the building heat load is relatively small.

  A ceiling C is provided in the air conditioning room R. For convenience of explanation, the ceiling C of the interior zone Zc is referred to as an interior ceiling Cc, and the ceiling C of the perimeter zone Zp is referred to as a perimeter ceiling Cp. The perimeter ceiling Cp includes an outdoor-side ceiling Cpp that is recessed upward along the side wall SW, and an indoor-side ceiling Cpc that is lower than the outdoor-side ceiling Cpp. If the outdoor-side ceiling Cpp is recessed upward at least over the width of the window glass WG, it functions as a blind box (shielding member box) that can accommodate the blind 21. The indoor ceiling Cpc is provided flush with the interior ceiling Cc.

  The perimeter radiating panel 11 is a radiating panel capable of changing the temperature of the perimeter ceiling Cp in a range where heat is transmitted to a temperature different from the temperature of the surrounding air, and is an upper horizontal radiation provided on the horizontal surface of the outdoor side ceiling Cpp. The panel 12 includes a vertical radiating panel 13 provided on the vertical surface of the outdoor side ceiling Cpp, and a lower horizontal radiating panel 14 provided on the indoor side ceiling Cpc. The upper horizontal radiating panel 12, the vertical radiating panel 13, and the lower horizontal radiating panel 14 are referred to for ease of distinction depending on the installation location, and have the same functions and structures. Therefore, when individually explaining these, they are called differently, and when referring to common matters, they are collectively called “perimeter radiation panel 11”.

  The perimeter radiating panel 11 is configured such that a pipe for flowing cold / warm water CH as a heat medium (cool water during cooling and warm water during heating) is disposed on one surface of the panel formed in a plate shape. Yes. The panel typically has a rectangular (rectangular or square) planar shape, but may have a polygonal planar shape such as a triangle or a hexagon. It is preferable to increase the heat transfer area by arranging the pipes in a meandering manner so that the cold heat or hot heat of the cold / hot water CH can be transmitted to the entire panel. The perimeter radiating panel 11 may itself constitute the perimeter ceiling Cp, and is configured separately from the ceiling finishing material forming the perimeter ceiling Cp, and transmits cold heat or heat to the ceiling finishing material. It may be attached so that

  The blind 21 is typically a Venetian blind configured by connecting a plurality of metal or plastic louvers (slats) with a thread (string). The blind 21 has an area larger than that of the window glass WG, and can cover the window glass WG. The blind 21 may be formed integrally or may be divided into a plurality of parts. When the blind 21 is divided into a plurality of parts, typically, the vertically long ones are arranged in the horizontal direction. The blind 21 can be configured to change the light intensity and the direction in which the scenery of the outdoor EX can be seen by adjusting the angle of the louver and to expose the window glass WG by rolling up the louver. In the present embodiment, when the louver is rolled up and the window glass WG is exposed, the blind 21 is in the “open” state, and when the louver is only changed, the blind 21 is not rolled up. It is assumed that the state is “closed”.

  The blind 21 is attached to the horizontal surface of the outdoor side ceiling Cpp via the spacer 25. The blind 21 is attached at a position where a gap S is formed with the window glass WG. Here, the clearance S increases the effective area of the heating / cooling room R at a distance that does not hinder the upward air flow when the air between the window glass WG and the blind 21 flows upward due to temperature rise. From the viewpoint, it should be as small as possible, for example, 10 mm to 70 mm, preferably 30 mm, and other dimensions may be used. It is preferable that the blind 21 is attached to the center of the depth direction (the direction away from the window glass WG to the inside of the heating / cooling room R) with respect to the horizontal surface of the outdoor-side ceiling Cpp. In other words, it is preferable that the depth of the horizontal surface of the outdoor side ceiling Cpp is formed to a dimension obtained by adding twice the distance of the gap S and the thickness of the blind 21. In this way, when the air rising between the window glass WG and the blind 21 exceeds the upper end of the blind 21 and enters the inside of the heating / cooling room R, the air is applied to the vertical surface of the outdoor side ceiling Cpp. It can be a downward flow.

  The spacer 25 is a member interposed so that the horizontal plane of the outdoor side ceiling Cpp and the upper end of the blind 21 can maintain a predetermined distance Lh. Here, the predetermined distance Lh is a distance that does not hinder the air flow between the horizontal surface of the outdoor-side ceiling Cpp and the upper end of the blind 21. Further, the predetermined distance Lh is a distance that allows the air flowing between the horizontal surface of the outdoor side ceiling Cpp and the upper end of the blind 21 to exchange heat with the upper horizontal radiation panel 12 (the horizontal surface of the outdoor side ceiling Cpp). Is preferred. In addition, the heat exchange amount by natural circulation becomes large, so that the length of the vertical direction of the vertical radiation panel 13 of the outdoor side ceiling Cpp is large. In consideration of such conditions, the spacer 25 is formed to have an arbitrary length in the range of 10 mm to 300 mm, and in particular, to have an arbitrary length in the range of 75 mm to 150 mm or in the range of 150 mm to 300 mm. It is good to be. Further, when the spacer 25 is made of iron or a material having a higher thermal conductivity than iron, for example, aluminum, copper, zinc, or nickel, the spacer 25 transmits the cold or warm heat of the upper horizontal radiating panel 12 to the blind 21. Since it becomes easy, it is suitable. The spacer 25 may be a fastening member itself such as a bolt, or may be a cylindrical member through which the bolt or the like is inserted. A plurality of spacers 25 are provided on the support frame (rail) at the upper end of the blind 21 at an appropriate interval to ensure air circulation. In other words, the plurality of spacers 25 make the blind 21 to the outdoor-side ceiling Cpp. Mounted on a horizontal surface.

  The air conditioning room R is further provided with a radiating panel (hereinafter referred to as “interior radiating panel 16” for distinction from the perimeter radiating panel 11) on the interior ceiling Cc. The interior radiating panel 16 includes a plate-like panel and a pipe through which the cold / hot water CH flows, like the perimeter radiating panel 11, and has the same function and structure as the perimeter radiating panel 11. Similarly to the perimeter radiating panel 11, the interior radiating panel 16 may itself constitute the interior ceiling Cc, and is configured separately from the ceiling finishing material forming the interior ceiling Cc. It may be attached so that cold or warm heat can be transmitted.

  The upper horizontal radiating panel 12, the vertical radiating panel 13, the lower horizontal radiating panel 14, and the interior radiating panel 16 are connected by a cold / hot water pipe 18 so that the pipes communicate with each other. In the cold / hot water pipe 18, the cold / hot water CH first flows into the pipe of the interior radiant panel 16, and then flows in the order of the pipe of the lower horizontal radiant panel 14, the pipe of the vertical radiant panel 13, and the pipe of the upper horizontal radiant panel 12. Are arranged in a manner to form. The cold / hot water CH typically circulates between a heat source device (not shown) such as a cold / hot water generator, and the cold / hot water has a relatively large difference from the temperature in the air conditioning room R (ambient environment temperature). The water CH is introduced into the pipe of the interior radiating panel 16, and the chilled / hot water CH having a relatively small difference from the temperature in the air conditioning room R is led out from the pipe of the upper horizontal radiating panel 12. In addition, the cold / hot water pipe | tube 18 in drawing is shown in the aspect which mainly demonstrates a connection relationship, and is actually arrange | positioned along the ceiling C rather than arrange | positioning in the ceiling chamber middle.

  With continued reference to FIG. 1, the operation of the cooling and heating system 1 will be described. First, the effect | action at the time of the cooling of the air conditioning system 1 is demonstrated. At the time of cooling, the blind 21 is closed from the viewpoint of improving the cooling efficiency by blocking the solar radiation into the air conditioning room R. And in order to cool the air conditioning room R, the cold / hot water CH cooled by the heat-source apparatus (not shown) is introduce | transduced into the pipe of the interior radiation panel 16. FIG. The cold / hot water CH introduced into the interior radiant panel 16 also cools the interior ceiling Cc of the portion in contact with the interior radiant panel 16 by cooling the interior radiant panel 16, and the temperature rises itself (for example, from 20 ° C. Increased to 22 ° C.). The interior ceiling Cc of the portion cooled by the cold heat held by the cold / hot water CH radiates cold heat to objects (including people) in the air conditioning room R (strictly speaking, absorbs heat from the objects in the air conditioning room R), The interior zone Zc in the air conditioning room R is cooled.

  The cold / hot water CH derived from the interior radiant panel 16 is introduced into the lower horizontal radiant panel 14, and then passes through the upper horizontal radiant panel 12 via the vertical radiant panel 13 and then derived from the upper horizontal radiant panel 12. The cold / hot water CH flowing through the lower horizontal radiating panel 14, the vertical radiating panel 13, and the upper horizontal radiating panel 12 respectively has an indoor side ceiling Cpc and an outdoor side ceiling Cpp (both vertical and horizontal planes) in contact with the perimeter radiating panel 11. Each cools itself to increase its temperature (for example, from 22 ° C. to 24 ° C.). The indoor side ceiling Cpc and the outdoor side ceiling Cpp of the portion cooled by the cold heat held by the cold / hot water CH cool adjacent air. Moreover, the indoor side ceiling Cpc and the outdoor side ceiling Cpp of the cooled part also contribute to cooling of the blind 21 by radiation of cold heat. In general, since the perimeter zone Zp has a larger building heat load than the interior zone Zc, the cold / hot water CH after cooling the interior radiation panel 16 can be used to cool the perimeter ceiling Cp.

  While the perimeter ceiling Cp of the part in contact with the perimeter radiating panel 11 is cooled, the adjacent air is cooled, while the air in the space S sandwiched between the window glass WG and the blind 21 is caused by solar radiation. The temperature rises (for example, 40 ° C. or higher). The warmed air in the space of the gap S rises toward the horizontal plane of the outdoor side ceiling Cpp due to the decrease in density. The rising air passes between the horizontal surface of the outdoor side ceiling Cpp and the upper end of the blind 21, and moves to the inside of the heating / cooling room R beyond the blind 21. At this time, the air in contact with the outdoor side ceiling Cpp is cooled, the density increases, and descends along the blind 21 inside the air conditioning room R. By such a continuous movement of air, the air naturally circulates due to the density difference so as to rise on the window glass WG side along the blind 21 and descend on the inside of the heating / cooling room R, and the circulating flow of air is It is formed. By this circulation flow, the inside of the cooling / heating room R of the blind 21 is cooled, the temperature rise of the blind 21 is suppressed, and the cooling effect is further improved. Furthermore, since this circulation flow is natural circulation due to a difference in air density, no additional power is required to generate the circulation flow. Thus, according to the air conditioning system 1, it becomes possible to improve the thermal environment of the perimeter zone Zp while suppressing energy consumption.

  Next, with reference to FIG. 2, the effect | action at the time of the heating of the air conditioning system 1 is demonstrated. At the time of heating, the blind 21 is opened from the viewpoint of incorporating solar radiation into the air conditioning room R to contribute solar heat to heating. And in order to heat the air conditioning room R, the cold / hot water CH heated with the heat-source apparatus (not shown) is introduce | transduced into the pipe of the interior radiation panel 16. FIG. The cold / hot water CH introduced into the interior radiant panel 16 heats the interior radiant panel 16 to heat the interior ceiling Cc in contact with the interior radiant panel 16, and the temperature of the chilled water CH itself decreases (for example, from 30 ° C.). Reduced to 28 ° C.). The interior ceiling Cc of the portion heated by the warm heat held by the cool / warm water CH radiates warm heat to objects (including people) in the cooling / heating room R and heats the interior zone Zc in the cooling / heating room R.

  The cold / hot water CH derived from the interior radiant panel 16 is introduced into the lower horizontal radiant panel 14, and then passes through the upper horizontal radiant panel 12 via the vertical radiant panel 13 and then derived from the upper horizontal radiant panel 12. The cold / hot water CH flowing through the lower horizontal radiating panel 14, the vertical radiating panel 13, and the upper horizontal radiating panel 12 heats the perimeter ceiling Cp of the portion in contact with the perimeter radiating panel 11, and the temperature itself decreases (for example, 28 ° C.). To 26 ° C.). The perimeter ceiling Cp of the portion heated by the warm heat held by the cold / hot water CH heats adjacent air. Generally, the perimeter zone Zp has a larger building heat load than the interior zone Zc (it is more susceptible to outside air), so the cold / hot water CH after heating the interior radiation panel 16 is used to heat the perimeter ceiling Cp. can do.

  Under a thermal environment where heating is performed, the air adjacent to the window glass WG is cooled more than the air adjacent to the wall other than the window glass WG, and the density becomes higher. The air with the increased density of the window glass WG descends and flows so as to scoop the floor. As the air accompanying the window glass WG descends, the air near the ceiling moves in the direction of the window glass WG. At this time, the air near the ceiling is warmed by the perimeter ceiling Cp of the portion heated by the perimeter radiation panel 11. For this reason, even if the air that has come down from the ceiling passes through the side of the window glass WG and is cooled, a decrease in the temperature of the air when it reaches the floor is suppressed, and a cold draft in the air conditioning room R is suppressed.

  Even during heating, the blind 21 may be closed (see FIG. 1), for example, as represented at night. Even in such a case, in the air conditioning system 1, a space in which air corresponding to the length of the spacer 25 circulates is formed between the horizontal surface of the outdoor side ceiling Cpp and the upper end of the blind 21. As the air in the space S between the blind 21 and the blind 21 is cooled and lowered, the air warmed by the perimeter ceiling Cp flows over the blind 21 into the clearance S and suppresses the cold draft. can do.

  In the above description, the ceiling temperature changer is a radiant panel (perimeter radiant panel 11). However, other than the radiant panel, for example, electrical energy such as equipment that absorbs and releases heat using the Peltier effect. You may use the apparatus which operate | moves by. In addition, although the heat medium introduced into the perimeter radiating panel 11 is water (cold / warm water CH), it may be a fluid other than water (for example, brine). The heat medium is typically a fluid and can flow in the pipe.

  In the above description, the shielding member is a blind. However, a member such as a curtain that can block sunlight other than the blind may be used. Also in this case, there is no shielding member in the vicinity of the window glass WG, and the shielding member is open in a state where the window glass WG appears as viewed from the cooling / heating room R (in the case of a curtain, bundled together). The state where the shielding member is present between the window glass WG when viewed from the cooling / heating room R (the state where the shielding member is pulled in the case of a curtain) is a state where the shielding member is closed.

  In the above description, the perimeter ceiling Cp includes the outdoor-side ceiling Cpp that is recessed upward to the extent that the blind 21 can be accommodated. However, even if the entire perimeter ceiling Cp is configured to be flush with the interior ceiling Cc. Good. In addition, the perimeter radiation panel 11 includes the upper horizontal radiation panel 12, the vertical radiation panel 13, and the lower horizontal radiation panel 14, but depending on the conditions of the cooling / heating room R (for example, the direction of the window glass WG, etc.) The vertical radiating panel 13 and / or the lower horizontal radiating panel 14 may be omitted.

  In the above description, the blind 21 is attached to the perimeter ceiling Cp via the spacer 25. However, the height of the blind 21A is directly attached to the outdoor side ceiling Cpp (perimeter ceiling Cp) as shown in FIG. An opening whose direction is a predetermined distance Lh may be formed in the blind 21. In the air conditioning system 1A according to the modification shown in FIG. 3, the louvers (slats) on the upper part of the blind 21A are removed by the number corresponding to the predetermined distance Lh. The portion from which the louver has been removed is an opening except that a thread (string) connecting the remaining louvers appears. And the prism-shaped support frame of the upper end of the blind 21A is directly attached to the outdoor side ceiling Cpp using the attachment metal fitting (not shown). This state of being directly attached is a state of being attached in such a manner that the circulation of air that circulates naturally is obstructed unless the louver is removed. The configuration of the air conditioning system 1A other than the above is the same as that of the air conditioning system 1 (see FIGS. 1 and 2). In the air conditioning system 1A configured as described above, an opening whose height direction is a predetermined distance Lh is formed immediately below the support frame of the blind 21A directly attached to the outdoor-side ceiling Cpp. For example, during cooling, warmed air in the space S rises, collides with the horizontal surface of the outdoor ceiling Cpp, changes direction, and moves to the inside of the cooling / heating room R. At this time, the support frame of the blind 21A tries to prevent the air flow, but since an opening of a predetermined distance Lh is formed immediately below, the warmed air is not disturbed in the air conditioning room R. Can move inward. In addition, when air flows so that it may avoid the support frame of the blind 21A, it may arise that it leaves | separates from the horizontal surface of the outdoor side ceiling Cpp, and exchange heat amount reduces. Even in this case, it is preferable that the vertical radiating panel 13 is provided on the vertical surface of the outdoor side ceiling Cpp, because heat can be exchanged by the air contacting the vertical surface of the outdoor side ceiling Cpp. The air conditioning system 1A has an advantage that when the blind 21A is opened, there is no space between the blind 21A and the ceiling surface, so that it can be stored compactly.

  Moreover, it is good also as the perimeter radiation | emission panel 11 being provided with the form as shown to Fig.4 (a). 4A and 4B are diagrams showing a modification of the installation mode of the perimeter radiating panel 11, wherein FIG. 4A is a partial side sectional view around the outdoor-side ceiling Cpp, and FIG. 4B is a perspective view of the radiating panel used in this modification. (C) is a partial side view of the radiation panel of another form used for this modification. In the installation mode according to the modification shown in FIG. 4A, the upper horizontal radiating panel 12 and the vertical radiating panel 13 are installed inside the outdoor-side ceiling Cpp that is recessed upward. In the modification shown in FIG. 4A, since the outdoor-side ceiling Cpp recessed upward functions as a blind box, the upper horizontal radiation panel 12 and the vertical radiation panel 13 are attached to the inside of the blind box. Can see.

  As shown in FIG. 4 (b), the perimeter radiation panel 11B used in the modification shown in FIG. 4 (a) (reference numeral “11B” is used to distinguish the one used in this modification from the aforementioned one). Is configured as follows. The perimeter radiation panel 11B includes a panel 11b whose basic shape is a rectangular plate, and a pipe 11p through which cold / hot water CH flows. In this modification, the panel 11b is formed in a rectangular shape in plan view, and is formed with a recess 11bd that accommodates the pipe 11p so that the short side is divided into two and extends in parallel with the long side. The recess 11bd is formed in a semicircular arc shape whose bottom is substantially coincident with the outer periphery of the pipe 11p so as to be in contact with about half of the surface of the pipe 11p, and the depth is substantially equal to the outer diameter of the pipe 11p. Yes. The recess 11bd may have less than about half the portion in contact with the surface of the pipe 11p, but may be configured to be able to transmit the heat held by the cold / hot water CH over a wide range of the panel 11b. At the four corners of the panel 11b, insertion holes 11bh for inserting fixing fastening members (screws or the like) are formed. The panel 11b is preferably made of a material having high thermal conductivity from the viewpoint of increasing the amount of heat transferred to the surrounding air, and is preferably a lightweight material from the viewpoint of improving workability. It is made of aluminum. The pipe 11p is connected to a cold / hot water pipe 18 (see FIG. 1 (a)), and the cold / hot water CH flows therein. Typically, the cold / hot water pipe 18 is disposed behind the ceiling, and a part of the ceiling finishing material is perforated and guided into the blind box. A hole formed to penetrate the cold / hot water pipe 18 is concealed by the panel 11b. Further, the pipe 11p is sandwiched between the ceiling finishing material and the panel 11b so as not to be seen from the inside of the air conditioning room R. When the perimeter radiating panel 11 configured in this way is attached to the inside of the blind box, the heat of the cold / hot water CH flowing through the pipe 11p spreads over the entire panel 11b, and heat radiation is performed from the panel 11b, and the adjacent air is removed. Cool or heat.

  In addition, a perimeter radiating panel 11C having the form shown in FIG. 4C (represented by “11C” in order to distinguish another form used in this modification from the above-described form) may be used. The perimeter radiating panel 11C includes a rectangular plate-shaped panel 11c and a pipe 11p through which cold / hot water CH flows. The panel 11c is configured such that a support 11cs for holding the pipe 11p is integrally attached to the surface. The support 11cs has a shape in contact with approximately 3/4 of the outer periphery of the pipe 11p when viewed in a cross section perpendicular to the axis of the pipe 11p. When the pipe 11p is fitted, the support 11cs is elastically deformed so that the opening is widened, and when the pipe 11p is attached, the support 11cs returns to the original and grips the pipe 11p. The material of the panel 11c is also selected from the same viewpoint as the panel 11b (see FIG. 4B), and is typically formed of aluminum. The pipe 11p has the same configuration as that used in the perimeter radiation panel 11B (see FIG. 4B), and the heat of the cold / hot water CH flowing inside spreads over the entire panel 11c, and heat radiation is performed from the panel 11c. The point which cools or heats adjacent air is the same as that of perimeter radiation panel 11B (refer to Drawing 4 (b)). When the perimeter radiating panel 11C is used, a part of the pipe 11p may be seen from the inside of the air conditioning room R.

  If the upper horizontal radiating panel 12 and the vertical radiating panel 13 are mounted inside the blind box as in this modification, cooling or heating of adjacent air can be performed more efficiently. Further, the blind box is an off-the-shelf product formed of steel plate, and the back surface (the surface located on the back of the ceiling) is joined to a protrusion such as a rib for fixing or reinforcing to the ceiling base material, or a blind box that is separately carried in Even if it is difficult to install the radiating panel on the back surface because of the flange for use, it can be installed easily because it is attached to the inside of the blind box. Further, even when the blind box is made of wood, it can be easily installed and the inner surface of the blind box can be made of a material having a higher thermal conductivity than wood.

  In the modification shown in FIG. 4A, a blind box 50 with a perimeter radiating panel in which a perimeter radiating panel 11B (11C) is attached to the inside of the blind box 51 is manufactured in advance at the factory, and this is carried to the site. By attaching, the blind box 51 constitutes the outdoor side ceiling Cpp, and the air conditioning system is constructed. At this time, the blind box 51 typically has a configuration in which one surface of an elongated rectangular parallelepiped (one form of hexahedron) is an opening 51h. The perimeter radiation panel 12 (11B, 11C) is attached to the bottom surface 51b of the blind box 51, and the perimeter radiation panel 13 (11B, 11C) is attached to the side surface 51s of the blind box 51. The blind box 50 with a perimeter radiation panel may be configured to be divided into a plurality of parts (and can be assembled and restored later) for convenience of carrying in.
