Description

  The present invention relates to an air-conditioning technology that circulates and supplies a heat medium to a radiator disposed in a building and cools and heats the building with hot air or cold air radiated from the radiator.

  A typical example of an air conditioning system that cools and heats a building is one that uses an air conditioner such as a so-called room air conditioner. The conventional air conditioner performs air conditioning by blowing an air flow that has been moderately temperature-controlled by an outdoor unit into the room from an indoor unit arranged in the building, but it blows out from the indoor unit, especially in the hot summer season Although it can be felt cool due to the feeling of airflow generated by the conditioned air, an unpleasant phenomenon called a draft may occur in some cases.

  Therefore, an all-plastic resin heating / cooling radiator that can perform indoor heating by hot water circulation and indoor cooling by cold water circulation has been proposed (for example, see Patent Document 1). The all-plastic resin heating / cooling radiator disclosed in Patent Document 1 employs a header in which a branch pipe group for medium-diameter joints is juxtaposed in a lateral direction from a large-diameter header main pipe, and a small-diameter vertical pipe between upper and lower headers. The group is connected to form an all-plastic heat dissipating panel, and two heat dissipating panels having the same structure are connected and integrated in a multilayered form.

  A conventional heat radiating panel (hereinafter referred to as “fence-like panel”) such as an all plastic radiating panel constituting the “all plastic resin heating / cooling radiator” described in Patent Document 1 is, for example, a fence shown in FIG. The one having a structure like the panel 80 is typical.

  As shown in FIG. 8, the fence-like panel 80 is connected to the plurality of vertical pipes 81, 81a arranged in parallel to each other and to the upper ends and lower ends of the plurality of vertical pipes 81, 81a, 81b, respectively. The upper header pipe 82 and the lower header pipe 83 are provided, and in the upper header pipe 82, the partitioning means 84 is disposed in a portion located between the vertical pipe 81a at the right end and the vertical pipe 81b on the left side thereof. Thus, a small chamber 85 is formed at the right end portion of the upper header pipe 82. The small chamber 85 at the right end of the upper header pipe 82 is provided with an inflow path 86 for introducing a heat medium into the vertical pipe 81a, and flows through the plurality of vertical pipes 81a, 81b, 81 at the left end of the upper header panel. An outflow path 87 for allowing the heated heat medium to flow out is provided.

  The heat medium supplied from the outside in a state adjusted to a predetermined temperature flows into the small chamber 85 via the inflow path 86, flows down in the vertical pipe 81 a located at the right end, and flows into the lower header pipe 83. Then, while flowing toward the left end portion, the inside flows into the plurality of vertical pipes 81, 81 b, flows upward inside each, and is a region on the left side from the partition means 84 in the upper header pipe 82. Flows in. The heat medium that has flowed into the region in the upper header pipe 82 flows toward the outflow path 87 at the left end portion of the upper header pipe 82, flows out of the outflow path 87, and reaches the back side of the fence-like panel 80. It flows into the upper header pipe of another arranged fence-like panel (not shown). In this way, air conditioning is performed by causing the temperature-adjusted heat medium to flow into the fence-like panel 80 and releasing warm air or cold air from the surface of the fence-like panel 80.

  The “all plastic resin heating / cooling radiator” described in Patent Document 1 is excellent in that a comfortable air-conditioned space can be realized by a radiating action while being in a no-wind state, as shown in FIG. Thus, in the heat dissipation panel (fence-like panel 80) constituting the “all plastic resin heating / cooling radiator”, the heat medium does not flow evenly over the entire area of the fence-like panel 80, and its vicinity (region X ) May cause temperature unevenness. That is, the air conditioning efficiency may be reduced due to temperature unevenness in which the region X in the fence-like panel 80 becomes hotter than other portions during cooling and the region X becomes colder than other portions during heating. There is a demand for uniform temperature distribution of the fence-like panel 80.

  With such a configuration, in the fence-like panel, the plurality of vertical pipe groups through which the heat medium flows is divided into a plurality of groups, and the heat medium is circulated for each group, whereby the heat for each vertical pipe is distributed. Since the flow rate of the medium can be equalized, the temperature unevenness that has occurred in the conventional fence-like panel 80 shown in FIG. 8 (as shown in FIG. 8, the region X becomes hot during cooling and during heating, The temperature unevenness that the region X becomes low temperature is eliminated, the temperature distribution of the fence-like panel is made uniform, and the air conditioning effect is improved.

  Here, the partition means is arranged near the center in the length direction of the upper header flow path and the lower header flow path, and the vertical pipe group is divided into two groups having the same number of vertical pipes. It is desirable to do.

  With such a configuration, the temperature distribution can be made uniform with a minimum number of groups, so that the air conditioning effect can be improved while avoiding the complexity of the heat medium flow path accompanying the increase in the number of groups. Can do.

  With such a configuration, the lower header flow path and the orifice member can be separated from each other. Therefore, if an orifice member having an orifice hole corresponding to the size of the fence-like panel and construction conditions is manufactured, the lower header While sharing the flow path and the fence-like panel, the temperature distribution of the fence-like panel can be made uniform. In addition, after construction, if the temperature distribution of the fence-like panel is uneven due to changes in usage conditions etc., it can be easily handled by replacing it with another orifice member with a different inner diameter of the orifice hole. it can.

  In this case, it is preferable that the orifice member has a plurality of orifice holes along the longitudinal direction of the flange-like member that can come into surface contact with the inner peripheral surface of the lower header flow path.

  Further, in the radiator 200, the temperature distribution can be made uniform by two groups, which is the minimum number of groups, so that the air conditioning effect can be reduced while avoiding the complexity of the heat medium flow path accompanying the increase in the number of groups. Improvements can be made.

  Further, in the radiator 200, as shown in FIG. 2, the heat medium supplied to the fence-like panel 201 and the heat medium flowing out from the fence-like panel 202 are caused to flow in the longitudinal direction of the upper header channels 205 and 206. Since the secondary flow paths 222b and 222c are provided in the intermediate header flow path 220, the inflow position (inflow pipe 223) of the heat medium supplied to the fence-like panel 201 and the outflow of the heat medium flowing out from the fence-like panel 202 are provided. The position (outflow pipe 224) can be set at a position separated along the longitudinal direction of the upper header channels 205 and 206. For this reason, piping for the heat medium suitable for the installation location of the radiator 200 can be performed, a working space for piping work can be secured, and piping work can be facilitated.

  On the other hand, in the air conditioning system 500 shown in FIG. 7, 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 atmospheric pressure in the building 10 is set to a positive pressure. It is supplied into the building 10 with a wind pressure (air volume) that can be maintained in the building. The outside air introduced by the air supply means 15 flows into the rooms 1, 2, 3, and 4 from the air supply ports 21a and 21 via the supply path 14 and the ventilation path 19, and then diffuses. The part is discharged to the outside 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 500, 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 according to an air conditioning load or the like, Since only one of the heat radiator 200 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 200 (for example, when only radiant air conditioning is to be executed), 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 and the circulation of the heat medium to the radiator 200 is stopped, the operation only for adjusting the temperature of the outside air is possible.

  Further, by using the heat source unit 12 that is the heat source of the radiator 200 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. Note that condensation may occur particularly on the surface of the radiator 200 in the summer, but if the outside air introduced into the building 10 is dehumidified and cooled in advance, the condensation generated on the surface of the radiator 200 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.

The system is not limited to the embodiment described above.
