Description

  The present invention relates to an intake / exhaust unit that controls the flow of air in an intermediate layer in a window glass having a double skin structure, a dehumidifying unit that prevents internal condensation in the intermediate layer, and a double skin system using them.

  In conventional buildings, a single sheet glass is often used as the window glass, which is in a very poor thermal efficiency. Since the glass sheet is easy to get heat in and out, the sunny side of the room is hot and the back of the room is cold. If the temperature varies in the room, the effectiveness of the air-conditioning equipment will be poor and the energy efficiency will be poor. That is, heat is not effectively utilized to maintain the room at an appropriate temperature.

  As described in Patent Document 1, by installing an inner glass (inner glass) on the indoor side of a plate glass (outer glass) to form a double skin structure, it is possible to reduce the window surface heat load due to solar radiation during cooling. For example, an invention of an inner glass skin structure for a double glass skin that can improve the heating efficiency by recovering heat of air heated by solar radiation or the like during heating is also disclosed. In particular, the use of warm air in winter is an energy-saving technique that can be realized by the intake air from the room, the heat exchange in the middle layer, and the exhaust path to the room, and it is difficult to easily construct the conventional technique.

  In order to make the window glass into a double skin structure, it is first necessary to be able to perform glass cleaning and blind maintenance in the intermediate layer without providing a maintenance deck. The invention described in Patent Document 1 has been solved. Next, it is necessary to easily and reliably control the air in the intermediate layer provided between the outer glass and the inner glass, and to withstand long-term practical use with less maintenance.

  When air control is performed in the intermediate layer, intake and exhaust ports are provided at the top and bottom on the outer glass side, and are opened or closed manually or automatically to perform intake or exhaust of outside air. In addition, in an aluminum curtain wall (removable wall), there is a system in which an outside air introduction mechanism is incorporated in a cross member or a vertical member. However, since it is natural intake / exhaust, the intake / exhaust performance changes due to changes in wind direction and wind speed, and it is difficult to predict the effect.

  The inner glass side that is not in direct contact with the outside air only needs to have at least a seismic performance, but since the outside air is taken into the intermediate layer, the wind pressure performance is also considered. The wind pressure resistance performance on the inner glass side is determined from the area of the intake / exhaust port on the outer glass side and the wind speed under open conditions, but it is necessary to assume several times from the viewpoint of safety. Although the operable wind speed depends on the area of the intake / exhaust port, it is about 10 meters per second. In particular, when a blind is installed in the intermediate layer, it becomes difficult to intake / exhaust. Furthermore, when inhaling outside air, it is difficult to install a filter at the intake and exhaust ports, and the number of internal maintenance increases.

  In the case of natural intake / exhaust, performance is also required to ensure complete sealing or opening for a long period of time against the design wind pressure. If it is not used for a long period of time, the sealing material may be stuck or the operation mechanism may be broken, so a maintenance plan that assumes that is also necessary. Also, forgetting to close the intake and exhaust ports during strong winds or rain, especially during storms, raises the internal pressure of the intermediate layer and causes serious problems such as affecting the blinds and the inner glass side. In order to overcome the above problems, the current situation is that the cost must be high.

Japanese Patent No. 5658813

  Even if the window glass has a double skin structure as described in Patent Document 1, it is meaningless unless heat can be effectively utilized, for example, air stays in the intermediate layer. In addition, there is no point in complicating the equipment to make effective use of heat, increasing the cost, or reducing the effect. If they can be eliminated, the hurdle to introducing a double skin structure will be lowered.

  Moreover, in the window glass of a double skin structure, there also exists a problem that an internal dew condensation generate | occur | produces in the intermediate | middle layer side of outer glass (outer glass). When the opening of the window glass is sealed against the outside air, the interlayer is suddenly cooled by the outside air separated by the outside glass, and when the temperature in the interlayer drops to the dew point, condensation forms on the inside of the outside glass. Arise. In automobile showrooms and other buildings, it is not preferable that internal condensation occurs on the window glass.

  Accordingly, an object of the present invention is to provide an intake / exhaust unit for easily controlling the air flow in the intermediate layer of a double-skin structure window glass and a double skin system using the same.

  Furthermore, another object of the present invention is to provide a dehumidification / exhaust / exhaust unit that prevents internal condensation in the intermediate layer and a double skin system using the same in a window glass having a double skin structure.

Then, air is sent to any one of the first, second, third or fourth distribution ports other than the suction port, and is sent from any one of the first, second, third or fourth distribution ports. In this case, the air humidity is adjusted by the dehumidifying means and sent out.

  The dehumidifying / exhaust / exhaust unit according to the first aspect of the invention includes a storage battery that accumulates electricity generated by a solar cell and supplies electricity to the fan.

  Embodiments of the present invention will be described below in detail with reference to the drawings. In addition, what has the same function attaches | subjects the same code | symbol, and the repeated description may be abbreviate | omitted.

  First, a double skin system using the intake / exhaust unit according to the present invention will be described. FIG. 1A is a front view of a window glass employing a double skin system, FIG. 1B is a right side view of the window glass employing a double skin system, and FIG. 1C is a double skin system. It is a top view of the window glass which employ | adopted. The double skin system 100 is configured to be used for each of a plurality of window glasses installed in a building. As shown in FIG. 1A, at least a double skin 200, an upper intake / exhaust unit 300, and a lower side The intake / exhaust unit 301 is provided.

  The double skin 200 is an opening portion of a window glass, and includes at least an outer glass 210 and an inner glass 220 as shown in FIG. As the outer glass 210, a plate glass similar to the existing window glass is used. As the inner glass 220, a double-glazed glass having heat insulating properties is used. Multi-layer glass is obtained by stacking a plurality of plate glasses and enclosing air or other gas between them, or by making a vacuum between them.

  The outer glass 210 is arranged on the outdoor side and heat easily enters and exits, but the inner glass 220 is arranged on the indoor side and hardly receives heat. The outer glass 210 and the inner glass 220 are provided with a predetermined gap when they are stacked, thereby providing the intermediate layer 230. The intermediate layer 230 is a space through which air can enter and exit. The air is warmed by the heat that enters the intermediate layer 230 from the outside through the outer glass 210, but the heat hardly enters the room from the intermediate layer 230 through the inner glass 220.

  The intermediate layer 230 may be provided with a blind 240. The blind 240 has a plurality of horizontally long louvers arranged vertically, and the light, heat, or field of view taken in from the outside is adjusted by changing the angle of each louver. When the opening of the blind 240 is made small to make it difficult to pass solar radiation, part of the light and heat transmitted through the outer glass 210 is accumulated in the blind 240, and part of it is irregularly reflected, so that the air on the outer glass side of the intermediate layer 230 is evacuated. warm. When the opening of the blind 240 is increased to facilitate passage of sunlight, the light and heat that have passed through the blind 240 are stopped by the inner glass 210 and warm the inner glass side of the intermediate layer 230.

  As shown in FIG. 1C, the intake / exhaust unit 300 is installed on the upper part of the double skin 200, and controls the flow of air between the outside, the room, and the intermediate layer 230 of the double skin 200. The intake / exhaust unit 300 and the outside allow air to enter and exit through the outside vent 400. The intake / exhaust unit 300 and the room allow air to enter and exit through the inner vent 410. The intake / exhaust unit 300 and the intermediate layer 230 allow air to enter and exit through the middle vent 420.

  Similarly, the intake / exhaust unit 301 is installed in the lower part of the double skin 200, and controls the flow of air between the outside, the room, and the intermediate layer 230 of the double skin 200. The intake / exhaust unit 301 and the outside allow air to enter and exit through the outside vent 401. The intake / exhaust unit 301 and the room allow air to enter and exit through the inner vent 411. The intake / exhaust unit 301 and the intermediate layer 230 allow air to enter and exit through the middle vent 421.

  The intake / exhaust units 300 and 301 integrate the functions of natural intake / exhaust of outside air with the intermediate device 230 as a main path and the functions of indoor intake and exhaust. In the intake / exhaust units 300 and 301, by electrifying the selection of the air volume and the intake / exhaust path, the environment in the building can be controlled artificially as well as automatically.

  When the pressure difference between the room and the outdoor is high, such as when the building is a high-rise building or when the wind is strong, the window glass is rarely opened and the airtightness is kept high. Even if the outside vents 400 and 401 are made small, air hardly naturally enters and exits. By installing the intake / exhaust units 300 and 301, an air flow is forcibly generated, and air enters and exits from the outer vents 400 and 401. Note that if the outer vents 400 and 401 are set to about 4 square centimeters, it is possible to secure the air volume.

  Electric power for the intake / exhaust unit 300 to control the flow of air is supplied from the solar cell 500. Similarly, electric power for the intake / exhaust unit 301 to control the flow of air is supplied from the solar cell 501. The solar cells 500 and 501 are devices that convert light energy into electric power, and for example, a plurality of elements having a photovoltaic effect are arranged in a panel shape. The solar cells 500 and 501 are attached to a place where it is easy to hit the sun, such as an outdoor window frame. In addition, when there is little solar radiation, you may provide an auxiliary power supply.

  Next, intake / exhaust control in the double skin system using the intake / exhaust unit will be described. 2 (a) is a side view showing intake / exhaust control executed mainly in winter, and FIG. 2 (b) is a side view showing intake / exhaust control executed mainly in summer, FIG. (C) is a side view which shows the intake / exhaust control mainly performed in an intermediate period.

  As shown in FIG. 2 (a), since it is cold in winter, the outdoor cold air is not taken in, the indoor cold air is sent to the intermediate layer 230 of the double skin 200, and the air is warmed in the intermediate layer 230 by solar radiation. By returning it to the room, warm air is sent into the room. Specifically, first, the lower intake / exhaust unit 301 is driven by the solar cell 501, and the upper intake / exhaust unit 300 is also driven by the solar cell 500.

  The intake / exhaust unit 301 takes in indoor air from the inner vent 411 and sends out air from the middle vent 421 to the intermediate layer 230. Heat from solar radiation enters the intermediate layer 230 from the outside through the outer glass 210, but does not enter the room from the intermediate layer 230 through the inner glass 220, so the air in the intermediate layer 230 is gradually warmed. The intake / exhaust unit 300 takes in the air in the intermediate layer 230 from the middle vent 420 and sends out air from the inner vent 410 into the room.

  Thereby, indoor air can be warmed and use of a heater can be suppressed. That is, thermal efficiency can be improved and energy efficiency can be improved. Moreover, in the case of the existing window glass, even if it is winter, the temperature rises by sunlight and becomes very hot when a heating effect is added. However, if warm air circulates, it is possible to prevent only the window from becoming hot.

  As shown in FIG. 2 (b), since the summer is hot and the room uses cooling equipment, the indoor air is prevented from escaping to the outside, and the air heated by the intermediate layer 230 is discharged to the outside. Another air is taken into the intermediate layer 230 from the outside. Specifically, first, the lower intake / exhaust unit 301 is driven by the solar cell 501, and the upper intake / exhaust unit 300 is also driven by the solar cell 500.

  The intake / exhaust unit 301 takes in outdoor air from the outer vent 401 and sends out air from the middle vent 421 to the intermediate layer 230. The air in the intermediate layer 230 is gradually warmed by heat from solar radiation. The intake / exhaust unit 300 takes in air in the intermediate layer 230 from the middle vent 420 and sends out air from the outer vent 400 to the outside of the room. That is, the air in the intermediate layer 230 is circulated and heat is also released.

  Thereby, since heat does not accumulate in the intermediate layer 230, it is difficult for heat to transfer into the room, and the cooling effect can be maintained. That is, since the use of the cooling device can be suppressed, the thermal efficiency can be improved and the energy efficiency can be improved. Moreover, in the case of the existing window glass, the temperature rises due to solar radiation near the window in summer, and the cooling effect is weakened. However, if the air circulates and heat does not accumulate, the temperature rise at the window can be suppressed, and the cooling effect can be suppressed from being weakened.

  As shown in FIG. 2C, in the intermediate period such as spring or autumn, ventilation is performed between the room and the outside, for example, taking outdoor air into the room or sending out indoor air to the outside. Specifically, first, the lower intake / exhaust unit 301 is driven by the solar cell 501, and the upper intake / exhaust unit 300 is also driven by the solar cell 500. In addition, FIG.2 (c) has shown the flow of two kinds of air about the case where air is taken in into the room from the outdoor.

  The first case is when the outdoor layer is warmed using the intermediate layer 230 and then taken into the room. The intake / exhaust unit 301 takes in outdoor air from the outer vent 401 and sends out air from the middle vent 421 to the intermediate layer 230. The intake / exhaust unit 300 takes in the air in the intermediate layer 230 from the middle vent 420 and sends out air from the inner vent 410 into the room.

  The second is a case where outdoor air is taken into the room as it is without passing through the intermediate layer 230. The intake / exhaust unit 301 takes in outdoor air from the outer vent 401 and sends out air from the inner vent 411 into the room. At the same time, the intake / exhaust unit 300 takes in outdoor air from the outer vent 400 and sends out air from the inner vent 410 into the room.

  In this way, in the double skin 200, the air temperature is controlled using the upper intake / exhaust unit 300 and the lower intake / exhaust unit 301, thereby adjusting the indoor temperature according to the outdoor environment. be able to. Thereby, not only can the room be in a comfortable state, but also the use of air-conditioning equipment can be suppressed, so that thermal efficiency and energy efficiency can be improved.

  Next, a specific apparatus configuration of the double skin system using the intake / exhaust unit will be described. FIG. 3 is a block diagram showing a configuration of a double skin system using an intake / exhaust unit. As described in FIG. 1, the double skin system 100 includes a double skin 200, an upper intake / exhaust unit 300, and a lower intake / exhaust unit 301. The double skin 200 has an outer glass 210, an inner glass 220, and an intermediate layer 240 secured between them, and the air discharged from the intake / exhaust unit 301 moves up the intermediate layer 240, and the intake / exhaust unit 300. Inhaled.

  As shown in FIG. 3, the intake / exhaust unit 300 installed on the upper portion of the double skin 200 includes a ventilation control module 310, a fan 320, and a storage battery 330. Similarly, the intake / exhaust unit 301 installed in the lower part of the double skin 200 includes a ventilation control module 311, a fan 321, and a storage battery 331. The air blow control modules 310 and 311 are components having a function of controlling the flow of wind, and have two functions of intake control for taking in air and exhaust control for sending out air.

  Specifically, the ventilation control module 311 sucks air from the outer vent 401 or the inner vent 411 as intake control, and out of the outer vent 401, the inner vent 411, and the middle vent 421 as exhaust control. , Exhale to places other than inhaled. When exhausted from the middle vent 421, the air is sent to the intermediate layer 240 between the outer glass 210 and the inner glass 220. The air in the intermediate layer 240 forms an upward flow by the exhaust control of the blow control module 311, the temperature rise due to solar radiation, the intake control of the blow control module 310, and the like. The air blow control module 310 sucks air from any one of the outer vent 401, the inner vent 411, and the middle vent 421 as intake control, and out of the outer vent 400 or the inner vent 410 as exhaust control. , Exhale to places other than inhaled.

  The air intake control and the exhaust control of the air supply control module 310 function by rotating the fan 320. Similarly, the intake control and exhaust control of the blower control module 311 are caused to function by rotating the fan 321. The fans 320 and 321 are blowers that generate wind by attaching a plurality of blades to a shaft and rotating the blades. For example, there is a sirocco fan and the like, and the air volume is adjusted by changing the rotation speed. If the air intake control module 310 and 311 specify the intake destination and the exhaust destination, respectively, the fans 320 and 321 are rotated to take in air from the intake destination and send out air to the exhaust destination.

  The air blowing control module 310 and the fan 320 supply electricity from the storage battery 330. Similarly, the ventilation control module 311 and the fan 321 supply electricity from the storage battery 331. By performing intake / exhaust electrically, it is possible to obtain a stable air volume that is not affected by weather conditions. The storage batteries 330 and 331 are batteries that can be used repeatedly by charging.

  The double skin 200 is mainly installed at a place where the influence of solar radiation is large. For this reason, electricity is generated by the solar battery 500, but the power generation may be suppressed. Therefore, if power generation is possible, the electricity is stored in the storage battery 330. And since the ventilation control modules 310 and 311 and the fans 320 and 321 have low power consumption, when driving them, the system can be constructed by supplying electricity from the storage batteries 330 and 331.

  With such a configuration, the air flow in the intermediate layer 240 in the window glass of the double skin 200 can be controlled by the intake / exhaust units 300 and 301, and the air warmed in the intermediate layer 240 is taken into the room. Or it can be exhausted to the outside. And the thermal efficiency of a building can be improved by employ | adopting the double skin system 100 using the intake / exhaust unit 300,301 for the window glass of a building.

  Next, the intake / exhaust unit according to the present invention will be described. FIG. 4 is a perspective view of the intake / exhaust unit. 5 (a) is a plan view of the intake / exhaust unit, FIG. 5 (b) is a front view of the intake / exhaust unit, and FIG. 5 (c) is a left side view of the intake / exhaust unit. Since the intake / exhaust unit 300 installed on the upper part of the double skin 200 and the intake / exhaust unit 301 installed on the lower part have the same structure, the intake / exhaust unit 300 will be described.

  As described with reference to FIG. 3, the intake / exhaust unit 300 includes the ventilation control module 310, and sucks air from any one of the outer vent 400, the inner vent 410, and the middle vent 420, and the outer vent 400, the inner vent 410, and the middle vent 420 other than the inhaled air are discharged. Therefore, as shown in FIG. 4, the air supply control module 310 is provided with three outlets, that is, a distribution port 340, a distribution port 350, and a distribution port 360.

  In addition, as shown in FIG. 5A, the intake / exhaust unit 300 includes a fan 320 and generates an air flow by wind. The side on which air is sucked by the fan 320 is connected to one of the distribution port 340, the distribution port 350, and the distribution port 360, and the side on which air is sent out by the fan 320 is connected to the distribution port 340, the distribution port 350, and Connect to any one of the distribution ports 360 other than those connected by suction.

  For example, the distribution port 340 is connected to the outer ventilation port 400, the distribution port 350 is connected to the inner ventilation port 410, and the distribution port 360 is connected to the middle ventilation port 420. As shown in FIG. 5B, it is assumed that a fan 320 is used that sucks the lower air by rotating the blades and blows out air from the side exhaust port using centrifugal force. In that case, if a route is formed below the fan 320 from the distribution port 340 and a route is formed from the fan 320 to the distribution port 360, air is sent from the outer vent 400 to the middle vent 420.

  The distribution port 340, the distribution port 350, and the distribution port 360 are not directly connected but are connected via the fan 320 therebetween. For example, first, the distribution port 340, the distribution port 350, and the distribution port 360 are divided. In addition, as shown in FIG. 5C, if the fan 320 is arranged on the upper side, a route from the distribution port 340 to the same side as the fan 320 and a route to the lower side of the fan 320 are formed separately. So that The same applies to the distribution port 350 and the distribution port 360.

  When the outer vent 400, the inner vent 410, and the middle vent 420, to which the distribution ports 340, 350, and 360 are connected, are closed, the inside of the intake / exhaust unit 300 becomes a substantially closed path. It is possible to prevent water leakage and increase in internal pressure due to various weather changes. That is, it functions as a safety device. Further, in the case of the intake / exhaust unit 300, since the intake and exhaust are secured by the fan 320, a filter can be provided.

  Furthermore, the internal structure of the intake / exhaust unit 300 will be described. 6A is a cross-sectional view taken along the line A shown in FIG. 5A, and FIG. 6B is a cross-sectional view taken along the line B shown in FIG. 5A. (C) is sectional drawing cut | disconnected by the C line | wire shown to Fig.6 (a). FIG. 7A is a cross-sectional view taken along line D shown in FIG. 6B, and FIG. 7B is a cross-sectional view taken along line E shown in FIG. 6B.

  As shown in FIG. 6A, in the air flow control module 310, the distribution port 340, the distribution port 350, and the distribution port 360 have a partition path 341, a partition path 351, and a partition, for example, by providing a partition. It is divided into a path 361. Further, as shown in FIG. 6B, the negative pressure path 370 on the lower side where the air is sucked into the fan 320 and the pressure is low, and the upper stage where the air is sent from the fan 320 and the pressure is high. The positive pressure path 380 on the side is separated from the fan 320 as a boundary.

  Then, as shown in FIG. 6A, an intake hole 342, an intake hole 352, and an intake hole 362 are provided as means for connecting the segmental path 341, the segmental path 351, and the segmental path 361 with the negative pressure path 370. .

The dehumidifying units 600 and 601 are used in combination with the intake and exhaust units 302 and 303. Specifically, the intake / exhaust units 302 and 303 suck in air from the intermediate layer 230 and send the air to the dehumidifying units 600 and 601. The dehumidifying units 600 and 601 adjust the humidity of the air sent from the intake / exhaust units 302 and 303 and return it to the intermediate layer 230. The dehumidifying units 600 and 601 may be incorporated in the intake / exhaust units 302 and 303 as dehumidifying means.

  Next, a specific apparatus configuration of a double skin system using a dehumidifying / exhausting unit will be described. FIG. 15 is a block diagram showing a configuration of a double skin system using an intake / exhaust unit and a dehumidifying unit.

  As shown in FIG. 15, the intake / exhaust units 302 and 303 installed at the upper part or the lower part of the double skin 200 include air blowing control modules 312 and 313, fans 320 and 321, and storage batteries 330 and 331.

The dehumidifying units 600 and 601 adjust the humidity of the sucked air and discharge it to the intermediate layer 240.

  Next, the dehumidification / intake / exhaust unit according to the present invention will be described. FIG. 16A is a perspective view of the intake / exhaust unit, and FIG. 16B is a perspective view of the dehumidifying unit. Since the intake / exhaust unit 302 and dehumidification unit 600 installed on the upper part of the double skin 200 and the intake / exhaust unit 303 and dehumidification unit 601 installed on the lower part have the same structure, the intake / exhaust unit 302 and dehumidification unit 600 will be described. To do.

  The intake / exhaust unit 302 includes a ventilation control module 312, and sucks air from any one of the outer vent 400, the inner vent 410, the middle vent 420, and the dehumidifying unit 600, and the outer vent 400 and the inner vent. Air is exhausted to any one of the mouth 410, the middle vent 420, and the dehumidifying unit 600 other than the inhaled one. Therefore, as shown in FIG. 16A, the air supply control module 312 is provided with four outlets, namely, a distribution port 340, a distribution port 350, a distribution port 360, and a distribution port 390.

  For example, the distribution port 360 is connected to the outer vent 400, the distribution port 350 is connected to the inner vent 410, the distribution port 360 is connected to the middle vent 420, and the distribution port 390 is connected to the dehumidifying unit 600. When a route is formed from the distribution port 360 to the lower side of the fan 320 and a route is formed from the fan 320 to the distribution port 390, air is sent from the middle vent 420 to the dehumidifying unit 600.

  Further, as shown in FIG. 16B, the dehumidifying unit 600 has an input port 610, an intake hole 620, an exhaust hole 630, and the like. The input port 610 is an opening through which the dehumidifying agent 611 is taken in and out of the dehumidifying unit 600. The intake hole 620 is an inlet that takes air into the dehumidification unit 600 and is connected to, for example, the distribution port 390 of the air blowing control module 312. The exhaust hole 630 is an outlet for sending air from the dehumidifying unit 600 and is connected to the intermediate layer 240, for example. It may be connected to the intermediate layer 240 through the middle vent 420.

  Next, a method for preventing dew condensation using the dehumidifying and aspirating unit according to the present invention will be described. When the double skin system 101 is employed in the building, a change switch may be provided for each double skin 200 in order to select and change the setting condition of each double skin 200, or the double skin 200 of each room may be provided. A change remote controller may be provided to selectively change the setting conditions. In addition, a change box for selecting and changing the setting conditions of the double skin 200 for each floor or the entire building may be provided.

  When the setting condition is changed, electricity is supplied from the storage batteries 330 and 331 of the intake / exhaust units 302 and 303 to the air blowing control modules 312 and 313, and the shutter 371 of the negative pressure path 370 and the shutter 381 of the positive pressure path 380 However, when the air slides to a preset position and air flows, the fan 320 is also driven. A flow of dehumidification air in the double skin 200 is created by a combination of the settings of the upper intake / exhaust unit 302 and dehumidification unit 600 and the settings of the lower intake / exhaust unit 303 and dehumidification unit 601. By registering the setting as an operation mode, the dehumidification control can be changed quickly and easily with a simple operation.

  FIG. 17 is a diagram illustrating the operation of the dehumidification / exhaust unit. The figure shown in the second stage is a plan view of the intake / exhaust unit, the figure shown in the third stage is a sectional view cut along the line A in the plan view, and the figure shown in the first stage is cut along the line B in the plan view. The figure shown on the left of the fourth stage is a cross-sectional view cut along line C of the plan view, and the figure shown on the right of the fourth stage is a cross-sectional view of the dehumidifying unit. Since the intake / exhaust unit 302 and the dehumidifying unit 600 are the same in structure as the intake / exhaust unit 303 and the dehumidifying unit 601, the intake / exhaust unit 302 and the dehumidifying unit 600 will be described. Moreover, since the operation | movement is the same as the case where a dew condensation is prevented and the case where a dehumidifying agent is dried, it abbreviate | omits about the part which overlaps description.

  The example in FIG. 17 is a setting that prevents condensation by adjusting the humidity of the air in the intermediate layer 240. In the winter, when the temperature of the intermediate layer 240 is lowered due to the outside air due to the outside air, the air is dried to prevent condensation. At this time, the desiccant 611 in the dehumidifying unit 600 absorbs moisture. Further, when the temperature of the intermediate layer 240 is increased in a dry state due to solar radiation or the like, moisture is given to the air. At this time, the desiccant 611 in the dehumidifying unit 600 is deprived of moisture and dried.

  As the desiccant 611, for example, a material having a porous structure such as silica gel that easily adsorbs moisture is used. Some desiccants 611 can be used repeatedly by releasing moisture when heat is applied while moisture is adsorbed. Note that the desiccant 611 is accommodated in a mesh-like mesh 612 having good air permeability in the dehumidifying unit 600 from the inlet 610 of the dehumidifying unit 600. The air that has entered from the intake hole 610 passes through the desiccant 611 in the mesh 612 and exits from the exhaust hole 620.

  As for the intake / exhaust unit 302, the intake hole 362 (c) is opened in the negative pressure path 370, and the exhaust hole 393 (z) is opened in the positive pressure path 380. When the fan 320 is driven, intake is performed at the distribution port 360 (3), and exhaust is performed at the distribution port 390 (4). In the intake / exhaust unit 302, the distribution port 340 (1) is connected to the outdoor, the distribution port 350 (2) is connected to the indoor, the distribution port 360 (3) is connected to the intermediate layer 230, and the distribution port 390 (4) is connected to the dehumidification unit 600.

In the dehumidifying unit 600, air flows in the order of the intake hole 620, the dehumidifying agent 611, the exhaust hole 630, and the intermediate layer 230. The intermediate layer 230, the dehumidifying unit 600, the intake / exhaust unit 302, and the intermediate layer 230 are formed by opening the intake hole 392 (d) in the negative pressure path 370 and opening the exhaust hole 363 (y) in the positive pressure path 380. The air may flow in this order.

  Next, the effect of the double skin system using the dehumidification / exhaust unit according to the present invention will be described. First, an example of a store (showroom or the like) employing the double skin system 101 is shown. The double skin system 101 has a structure in which an advertisement or the like is placed on the inner glass 220 and the inner glass 220 can be accommodated as necessary. The inner glass 220 is a multi-layer glass unit having high heat insulation and heat shielding performance, and the outer glass 210 is a general single plate glass.

  In winter, the inner glass 220 is accommodated and used only by the outer glass 210. The inside of the store is operated with heating air conditioning (for example, set temperature 20 degrees, humidity 40%). The inner glass 220 is disposed inside the outer glass 210 to form a double skin structure. Air having temperature and humidity is sealed in the intermediate layer 230 between the inner glass 220 and the outer glass 210. Here, it is assumed that the outside air temperature has decreased. The temperature on the outer glass side of the intermediate layer 230 decreases with a decrease in the outside air temperature, and condensation occurs when the dew point temperature (for example, 6 degrees) is reached.

  The dehumidifying unit 600 has a volume of 1.575 cubic meters with a width of 1.5 meters, a height of 3.5 meters, and a depth of 0.3 meters. The assumed temperature of the air in the intermediate layer 230 is 20 degrees and the relative humidity is 100%. The silica gel used as the dehumidifying agent 611 has a particle size of 0.5 to 0.9 millimeter, a weight of 740 grams per liter, and can absorb moisture up to 20% of the weight. That is, when 100 grams of the dehumidifying agent 611 is used, 20 grams of moisture can be absorbed.

  Since the amount of water vapor in air having a temperature of 20 degrees and a relative humidity of 100% is 17.23 grams per cubic meter, the amount of water vapor in the air in the intermediate layer 230 is 1.575 × 17.23 = 27. .14 grams. The required weight of silica gel is 27.14 / 0.2 = 135.7 grams and the required volume of silica gel is 135.7 / 740 = 0.183 liters.

  Moreover, when B type silica gel is used among silica gels, a moisture absorption rate changes with respect to relative temperature. The amount of moisture absorption is small in a low humidity environment, and the moisture absorption rate is high in a high humidity environment. When the silica gel absorbs moisture, the humidity in the intermediate layer 230 decreases, and the silica gel absorbs less moisture, the amount of moisture absorbed by the silica gel becomes close to that of the silica gel relative to the relative humidity. After using the dehumidifying unit 600, the humidity is balanced.

  In an initial state where the dehumidifying unit 600 is not used, when the temperature of the intermediate layer 230 is 20 degrees, the humidity is 50%, and the moisture content is 13.6 grams, the dew point temperature is 9.3 degrees. When 100 g of silica gel was used as the dehumidifying agent 611, the humidity dropped to 32%, the water content became 8.7 grams, the moisture absorption of the silica gel became 4.9 grams, and the dew point decreased to 2.8 degrees. When 200 g of silica gel was used as the dehumidifying agent 611, the humidity dropped to 28%, the moisture content was 7.6 grams, the moisture absorption of the silica gel was 6.0 grams, and the dew point was lowered to 1.0 degree. When 300 g of silica gel is used as the dehumidifying agent 611, the humidity is reduced to 20.3%, the moisture content is 5.5 grams, the moisture absorption of the silica gel is 9.1 grams, and the dew point is lowered to −3.6 degrees. It was.

Based on these results, it is possible to effectively prevent dew condensation by controlling the temperature in the intermediate layer 230 so as not to be lower than the dew point temperature in the humidity of the intermediate layer 230 at that time. By providing a sensor or the like for detecting temperature and humidity in the dehumidifying unit 600 or the like, an operation may be prompted by a warning, or automatic control can be performed.
(Modification)

  As mentioned above, although the Example of this invention was described, it is not limited to these. For example, not only the window glass of the double skin system 100 having the double skin 200 with the intake / exhaust units 300 and 301 is installed in the building, but the inner glass is installed on the indoor side of the window glass made of a single existing sheet glass. Alternatively, the double skin system 100 may be constructed by installing an outer glass on the outdoor side to form a double skin structure and installing the intake / exhaust units 300 and 301.

  In addition, the double skin 200 is not limited to a combination of a plate glass for the outer glass 210 and a multilayer glass for the inner glass 220, but the outer glass 210 and the inner glass 220 may be the same plate glass. The same multi-layer glass may be used, or the outer glass 210 may be a multi-layer glass and the inner glass 220 may be a combination of plate glasses.

  Further, the intake / exhaust units 300 and 301 may be only the upper intake / exhaust unit 300 or only the lower intake / exhaust unit 301 as long as they can intake and exhaust air. Further, in FIG. 3, not only the air flow of the intake / exhaust unit 301, the intermediate layer 230, and the intake / exhaust unit 300 but also the reverse flow of the intake / exhaust unit 300, the intermediate layer 230, and the intake / exhaust unit 301 can be controlled. good. The intake / exhaust unit 300 and the intake / exhaust unit 301 do not have to be the same device, and may be different devices as long as the intake / exhaust unit 300 and the intake / exhaust unit 301 can perform the same function.

  Any one of the distribution ports 340, 350, and 360 of the intake / exhaust unit 300 is connected to the discharge side except for one of the intake ports and the suction side. It may be designed to be connected to the side. Note that the air flow may be dispersed by increasing the number of openings 372 of the shutter 371 or the number of openings 382 of the shutter 381.

  In the double skin 200, the intake / exhaust units 300, 301 may be installed in a sash frame so that the intake / exhaust units 300, 301 exchangeable with the double skin 200 may be handled together. 301 may be installed on the ceiling or under the floor so that the double skin 200 and the replaceable intake / exhaust units 300 and 301 can be handled separately. It is also possible to easily change the double skin 200 and the single skin.
