  Hereinafter, based on FIGS. 1-7, the air conditioning system 300 using the heat radiator 100,200 and the heat radiator 100 which are embodiment of this invention is demonstrated. In addition, about the member which has the structure and function which are common in the heat radiators 100 and 200 and the air conditioning system 300, the same code | symbol is attached | subjected in FIGS.

  As shown in FIG. 7, which will be described later, a radiator 100 shown in FIG. 1 is an air conditioner arranged in a building 10 for air conditioning by circulating a temperature-controlled heat medium and releasing warm air or cold air from the surface. Fence-like panels 33 and 34 which are equipment, and have a plurality of vertical pipes 30 arranged in parallel to each other, and an upper header pipe 31 and a lower header pipe 32 connected to the upper and lower ends of the vertical pipe 30. Are arranged so as to be opposed to each other, and a flat surface portion 35 substantially parallel to the fence-like panel 33 is provided on the surface side of the radiator 100 (the outer surface side of the fence-like panel 33 positioned in front). ing. In addition, the outer surface side of the fence-like panel 33 means the surface on the opposite side of the surface where the two fence-like panels 33 and 34 face each other.

  Although not shown, the upper header pipe 31 of the fence-like panel 33 is provided with a pipe connection port for allowing a heat medium to flow into the fence-like panel 33. Pipe connection ports for allowing the heat medium to flow out from the inside of the fence-like panel 34 are provided, and pipes from temperature control means of the heat medium (for example, a heat source device such as a heat pump) are connected to these pipe connection ports, respectively. .

  As shown in FIGS. 2 and 3, the flat portion 35 is formed by mounting a plurality of flat members 36 on the surface side of the vertical pipe 30 constituting the fence-like panel 33. The flat member 36 includes a strip-shaped flat plate portion 36a and a U-groove-shaped locking portion 36b formed integrally with the flat plate portion 36a on the back side of the flat plate portion 36a. The outer periphery of the pipe 30 can be detachably gripped.

  In the present embodiment, the flat member 36 is mounted so that the long side direction of the flat plate portion 36 a of the flat member 36 is parallel to the longitudinal direction of the vertical pipe 30, and the length 36 t of the flat plate portion 36 a extends from the upper surface of the upper header pipe 31 to the lower header. The distance is set to be larger than the distance to the lower surface of the pipe 32. For this reason, the upper header pipe 31 and the lower header pipe 32 are in a state of being hidden on the back side of the flat portion 35, and the front view shape of the radiator 100 is only the flat surface of the flat portion 35, thereby providing a clean appearance. Can do.

  On the left and right side edge portions of the flat plate portion 36a, step portions 36c that engage with the side edge portions of the other flat plate portion 36a adjacent to the flat plate portion 36a are provided. The horizontal width 36 w of the flat plate portion 36 a is equivalent to the arrangement interval of the vertical pipes 30 of the fence-like panel 33. The flat member 36 is mounted on the front surface side of the vertical pipe 30 so that the outer periphery of the vertical pipe 30 of the fence-like panel 33 is gripped by the engaging portion 36 b of the flat member 36, and the vertical pipe 30 adjacent to the vertical pipe 30 is attached. The flat surface portion 35 is formed by joining the flat plate portion 36a of the flat surface member 36 to the flat plate portion 36c and the step portion 36c.

  The fence-like panels 33 and 34 (the vertical pipe 30, the upper header pipe 31, the lower header pipe 32, etc.) and the planar member 36 constituting the radiator 100 can be made of metal, ceramics or synthetic resin, From the viewpoint of durability such as corrosion resistance, synthetic resin is used in this embodiment. Specifically, although the fence-like panels 33 and 34 formed of PPR (polypropylene random copolymer resin) have a two-ply structure, the present invention is not limited to this.

  The material of the flat member 36 forming the flat portion 35 is not limited, but a synthetic resin material (for example, ABS resin or the same PPR resin (polypropylene random copolymer resin) as the fence-like panels 33 and 34) is preferable. Further, since the cross-sectional shape of the flat member 36 (the cross-sectional shape in the short side direction of the flat plate portion 36a) is the same at any location, the flat member 36 can be manufactured by extrusion molding.

  In the radiator 100, since the surface area of the fence-like panel 33 is increased by providing the flat surface portion 35, the heat radiation and cooling effect is enhanced and the air conditioning efficiency is improved. Further, the radiator 100 is placed in the room without the plane portion 35 (specifically, the surface portion of the fence-like panels 33, 34 (vertical pipe 30, upper header pipe 31, lower header pipe 32, etc.)) by the plane portion 35. Appearance is also good because the part that can be seen by the residents when installed) can be hidden. In addition, it is also possible to give decoration by coloring or printing on the surface of the flat plate portion 36a of the flat member 36 constituting the flat portion 35.

  Moreover, since the plane part 35 is formed by mounting a plurality of plane members 36 on the surface side of the vertical pipe 30 of the fence-like panel 33 located in front, the plane part 35 is formed by retrofitting. Can do. Further, since the planar member 36 is detachably attached to the vertical pipe 30 via the engaging portions 36b, only the planar member 35 can be replaced or cleaned, and maintenance and versatility are also good. It is.

  Further, the flat surface portion 35 is attached to the front surface side of the vertical pipe 30 with a strip-shaped flat member 36 having the longitudinal direction of the vertical pipe 30 as the long side direction, and between the adjacent vertical pipes 30 on the flat plate portion 36a side. It is formed by joining edges. Therefore, as described above, it is possible to form the flat portion 35 by retrofitting, but it is also possible to form the flat portion 35 at the same time that the vertical pipe 30 is disposed, thereby simplifying the manufacturing process. it can.

  Moreover, since the level | step-difference part 36c engaged with the side edge part of the other flat plate part 36a adjacent to the said flat plate part 36a is provided in the left and right side edge part of the flat plate part 36a, joining of flat plate parts 36a is carried out. The state can be stabilized.

  The radiator 100 shown in FIG. 1 is arranged near the wall in the building, and the flat surface portion 35 is provided only on the surface side of the radiator 100 (the outer surface side of the fence-like panel 33 positioned in front). Since it is not limited, it is also flat on the back surface side of the radiator 100 (the outer surface side of the fence-like panel 34 located at the rear, that is, the surface opposite to the surface on which the two fence-like panels 33 and 34 face each other). A portion 35 can be provided. With such a configuration, since the flat portions 35 are present on both the front surface side and the back surface side of the radiator 100, the radiator 100 can be effectively accommodated when it is installed as a partition rather than a wall. Can also be blindfolded.

  Although the heat radiator 100 shown in FIG. 1 includes two fence-like panels 33 and 34, the present invention is not limited to this, so one fence-like panel, or three or more fence-like panels. It can also be formed using. When a radiator is formed using one fence-like panel, a flat portion 35 can be provided on at least one of the front surface side and the back surface side of the radiator, and heat radiation is performed using three or more fence-like heats. When the radiator is formed, the flat portion 35 can be provided on at least one outer surface side of the fence-like panel located on the front surface side and the back surface side of the radiator.

  Next, in the radiator 200 shown in FIG. 4, as shown in FIGS. 5 and 6, the horizontal width 36xw of the flat plate portion 36xa of the plurality of flat members 36x constituting the flat portion 35x is equal to three adjacent vertical pipes. It is set to a size that can cover 30 front portions. On the back surface of the flat plate portion 36xa, a locking portion 36b that detachably holds the vertical pipes 30 on both sides of the vertical pipe 30 located in the center among the three adjacent vertical pipes 30 is provided.

  With the configuration like the radiator 200, the number of the planar members 36x forming the planar portion 35x can be reduced as compared with the case of the radiator 100 (see FIG. 1), and the locking portion 36b is connected to the vertical pipe 30. Since the gripping portion is also reduced, the construction work can be simplified. In the present embodiment, the horizontal width 36xw of the flat plate portion 36xa of the plurality of flat members 36x constituting the flat portion 35x is set to a size that can cover the front portion of the three adjacent vertical pipes 30. However, the present invention is not limited to this.

  Next, an air conditioning system 300 using the radiator 100 shown in FIG. 1 will be described based on FIG. As shown in FIG. 7, the air conditioning system 300 includes a radiator 100 disposed in each of a plurality of rooms 1, 2, 3, and 4 in the building 10, and the outside of the building 10 to adjust the temperature of the heating medium. The heat source machine (heat pump) 12 that is arranged, the first circulation path 13 that circulates the heat medium between the radiator 100 and the heat source machine 12, and the outside air is introduced into the building 10 to reduce the atmospheric pressure inside the building 10. The air supply path 14 and the air supply means (fan) 15 for maintaining a positive pressure, the cleaning means (filter) 16 for purifying the outside air introduced by the air supply means 15, and the air supply means 15 are introduced. A heat exchanger 17 for adjusting the temperature of the outside air, exhaust paths 5, 6, 7, and 8 through which air in the rooms 1, 2, 3, and 4 in the building 10 can flow out, the heat exchanger 17 and the heat source unit 12 And a second flow path 18 through which the heat medium is circulated.

  In the embodiment shown in FIG. 7, water is used as a heat medium that circulates between the heat source unit 12 and the radiator 100 via the first distribution path 13, but is not limited thereto. In addition, the size (performance) of the air supply means 15 is not limited, but the size that can satisfy the necessary ventilation (0.5 times / h) stipulated in the Building Standards Act according to the building 10 ( Performance) can be selected.

  The air supply path 14 is a room on the second floor side through a ventilation path 19 formed between the first floor ceiling part C1 and the second floor part F2 from the opening 10 opened in the outer wall part 10a of the room 2. The three and four air supply ports 21 communicate with each other. In the present embodiment, a ductless space that is hermetically insulated is formed between the first-floor ceiling portion C1 and the second-floor floor portion F2 of the building 10, and this ductless space is used as the ventilation path 19, and the rooms 1 and 2 on the first floor side. Are provided on the ceiling surfaces 1c and 2c of the rooms 1 and 2, respectively.

  Exhaust paths 5, 6, 7, and 8 are established in the outer wall portion 10a of each of the rooms 1, 2, 3, and 4. Each of the exhaust paths 5, 6, 7 and 8 is provided with a differential pressure adjusting means 9 having a backflow preventing function and a function of opening at a predetermined pressure difference. A rain-proof hood 10c is provided outside each of the exhaust paths 5, 6, 7, and 8.

  When the heat source device 12 and the air supply means 15 are operated in the air conditioning system 300, the heat medium whose temperature is adjusted in the heat source device 12 passes through the first distribution path 13 in each of the rooms 1, 2, 3, 4. It circulates and flows between the heat sink 100 and circulates and flows between it and the heat exchanger 17 via the second flow path 18. In parallel with this, the outside air sucked from the outside of the building 10 through the cleaning means 16 is supplied by the air supply means 15 via the heat exchanger 17, the air supply path 14, the opening 10b, and the like. It flows into the rooms 1, 2, 3, and 4 from the mouth 21.

  At this time, the blowing capacity of the air supply means 15 and the opening degree of the exhaust paths 5, 6, 7, and 8 are set so that the atmospheric pressure in the building 10 can maintain a positive pressure, and the heat source machine 12 and the air supply Any of the means 15 can be operated continuously (so-called 24-hour operation). Therefore, the air conditioning system 300 exhibits the 24-hour ventilation function of the second type ventilation method.

  In the air conditioning system 300, the heat medium whose temperature is adjusted by the heat source machine 12 according to the season (air temperature) is arranged in each room 1, 2, 3, 4 in the building 10 via the first distribution path 13. By circulating the radiator 100, radiant air conditioning is performed to heat or cool the interiors of the rooms 1, 2, 3, and 4 at an appropriate temperature by warm air or cold air discharged from each radiator 100. be able to. Moreover, in the air conditioning system 300, since it is not necessary to provide an electric blower fan etc. in the building 10, the inside of the building 10 can be kept quiet even when the air conditioning system 300 is operating.

  In the air conditioning system 300 shown in FIG. 7, the flat panel 35 (see FIGS. 1 and 2) is provided on the radiator 100 disposed in each of the rooms 1, 2, 3, and 4, thereby providing the fence-like panel 33. Therefore, the heat radiation effect is increased and the air conditioning efficiency is improved. Moreover, since the surface part of the fence-like panels 33 and 34 (the vertical pipe 30, the upper header pipe 31, the lower header pipe 32, etc.) can be hidden by the plane part 35, an external appearance property is also favorable. In addition, it is also possible to give decoration by coloring or printing on the surface of the flat plate portion 36a of the flat member 36 constituting the flat portion 35.

  Moreover, since the plane part 35 is formed by mounting a plurality of plane members 36 on the surface side of the vertical pipe 30 of the fence-like panel 33 located in front, the plane part 35 is formed by retrofitting. Can do. Further, since the planar member 36 is detachably attached to the vertical pipe 30 via the engaging portions 36b, only the planar member 35 can be replaced or cleaned, and maintenance and versatility are also good. It is.

  The outside air introduced by the air supply means 15 is purified by the cleaning means 16, adjusted to an appropriate temperature by the heat exchanger 17, and the wind pressure (air volume) that can maintain the atmospheric pressure in the building 10 at a positive pressure. Is supplied into the building 10. The outside air introduced by the air supply means 15 flows into the rooms 1, 2, 3, 4 from the air supply ports 21a, 21 via the air supply path 14 and the ventilation path 19, and then diffuses. A part is discharged to the outdoors through the exhaust paths 5, 6, 7, and 8.

  In the intermediate period when heating and cooling are not required, the operation of the heat source unit 12 is stopped and the functions of the radiator 100 and the heat exchanger 17 are stopped, while the air supply means 15 is continuously operated, thereby Two-hour ventilation can be performed for 24 hours. As the cleaning means 16, a filter having a function of trapping dust in the air is suitable, but an air washer or the like can also be used.

  Further, the ductless space formed between the first-floor ceiling portion C1 and the second-floor floor portion F2 of the building 10 is used as an air-tight heat-insulating air passage 19 that forms a part of the air-supply passage 14. Since the external airflow introduced into the rooms 1, 2, 3, 4 from the ports 21, 21a can be ensured, a reliable ventilation action can be obtained. Moreover, since the ventilation path 19 functions as an air supply path, it is not necessary to construct a duct connected to the air inlets 21 and 21a, and it is possible to reduce materials and facilitate construction. Further, since the radiation action is generated through the first floor ceiling C1 and the second floor F2 facing the ventilation path 19, it is effective in improving the air conditioning effect.

  In the air conditioning system 300, if a path opening / closing means (not shown) is provided in at least one of the first distribution path 13 and the second distribution path 18, by opening / closing the path opening / closing means in accordance with an air conditioning load or the like, Since only one of the radiator 100 connected to the first flow path 13 and the heat exchanger 17 connected to the second flow path 18 can be operated, it is effective in improving the air conditioning efficiency.

  For example, when it is desired to take outside air as it is while performing radiant air conditioning by the radiator 100 (for example, when only radiant air conditioning is desired), the path provided in the middle of the second distribution path 18 connected to the heat exchanger 17. This can be realized by closing the opening / closing means (not shown) and stopping the circulation of the heat medium to the heat exchanger 17. Further, if the path opening / closing means (not shown) provided in the first circulation path 13 is closed to stop the circulation of the heat medium to the radiator 100, the operation only for adjusting the temperature of the outside air is possible.

  In addition, by using the heat source unit 12 that is the heat source of the radiator 100 as the heat source of the heat exchanger 17, it is not necessary to separately provide a heat source for adjusting the temperature of the outside air introduced into the building 10. Simplification and reduction of installation space can be achieved.

  Furthermore, since the outside air is heat-exchanged by the heat exchanger 17 and introduced into the building 10, particularly in summer, the outside air that has been dehumidified and cooled can be introduced by cooling the high-temperature and high-humidity outside air. It can be in a comfortable state. In summer, condensation may occur particularly on the surface of the radiator 100. However, if the outside air introduced into the building 10 is dehumidified and cooled in advance, the condensation generated on the surface of the radiator 100 can be reduced.

  On the other hand, since the differential pressure adjusting means 9 having a backflow prevention function is provided in each of the exhaust paths 5, 6, 7 and 8, a predetermined pressure difference is generated between the pressure inside the building 10 and the pressure outside the building. It can be set, and the inside of the building 10 can always be kept at a stable positive pressure. In this case, it is desirable to set the pressure difference between the pressure inside the building 10 and the pressure outside the building to about 5 Pa to 10 Pa. Further, when the atmospheric pressure in the building 10 fluctuates due to an opening / closing operation of a door (not shown) provided in the building 10, the backflow prevention function of the differential pressure adjusting means 9 operates following this, so Intrusion of outside air from the paths 5, 6, 7, and 8 can be prevented.

  In addition, the air pressure inside the building 10 can be increased or decreased by increasing or decreasing the amount of air discharged from the exhaust paths 5, 6, 7 and 8 by the differential pressure adjusting means 9, so that the air pressure outside the building has changed. Even in this case, it is possible to set the contaminant intrusion prevention function to an appropriate state. Furthermore, since the differential pressure adjusting means 9 also has a backflow preventing means, when the positive pressure in the building 10 cannot be maintained due to a failure or stop of the air supply means 15, or due to strong winds, etc., the exhaust paths 5, 6, Even when a situation occurs in which outside air blows in toward 7, 8, it is possible to prevent the outside air containing contaminants from entering the building 10.

  The differential pressure adjusting means 9 having a backflow preventing function is not particularly limited, and those having a function of maintaining an open state at a predetermined pressure or higher and closing at a predetermined pressure or lower can be used. The differential pressure adjusting means 9 having a backflow prevention function is a differential pressure opening / closing means having a mechanism in which a weight or the like is attached to a blade that opens and closes due to a pressure difference, opens when a pressure difference exceeds a certain level, and closes with its own weight when the pressure difference disappears. Etc. can be used suitably. The set pressure may be set arbitrarily according to the number of attached weights. In this case, if the number of weights increases, the pressure at the time of opening increases, and the differential pressure with the outside air can be increased. If the number of weights decreases, the opening pressure decreases and the pressure difference with the outside air can be reduced. .

  In addition, it is also possible to provide an exhaust fan (not shown) in the exhaust paths 5, 6, 7, and 8 to perform 24-hour ventilation of the first type ventilation system. Also in this case, if the amount of air supplied from the opening 10b is set to be larger than the amount of exhaust from the exhaust paths 5, 6, 7 and 8, systematic ventilation is realized by the first type ventilation method. However, the inside of the building 10 can always be kept at a positive pressure. In addition, when the pressure difference set between the pressure inside the building 10 and the pressure outside the building is changed, it can be dealt with by changing the rotation speed of the exhaust fan.

  In the present embodiment, the building 10 has a high airtightness / high heat insulation structure, but is not limited to this, and therefore the air conditioning system of the present invention can be constructed even in a medium airtight / medium heat insulation structure, etc. Even in a modern building, the interior can always be kept quiet, comfortable and clean.
