The cavity formed between the outdoor glass and the indoor glass reduces the air conditioning load in the room if the heat insulation performance of the window is improved. In cold weather, the heating load can be reduced by effectively utilizing the air in the cavity warmed by sunlight. Further, in a hot season, the cooling load can be reduced by discharging the heat stored in the cavity to the outside.

When taking in the warm air in the cavity into the room, it is often the case that the openable indoor glass is manually operated. Since this opening / closing operation is left to the human sense of heat, it is difficult to perform this opening / closing operation at the optimum timing for reducing the air conditioning load.

In fact, it is often the case that the indoor glass that can be opened and closed is used with it closed. This includes the fact that the timing of the opening / closing operation is unclear, that a sufficient effect is obtained even when the cavity is closed, and that the heat utilization in the cavity is not recognized.

Therefore, an object of the present invention is to provide a control system that promotes heat utilization of a cavity formed by forming an opening of a building into a double-skin structure.

In order to solve the above-mentioned problems, the heat utilization promotion system of the cavity according to the present invention is inside the sashless which is slidably arranged along the rail laid on the indoor side of the outer glass installed in the opening. The glass and a door roller for traveling in the rail are attached and housed in the rail in advance, and the inner glass is formed after adjusting the inclination of the inner glass by the thickness of the cushioning material for receiving the inner glass. A movable setting block that is detachably placed and has a connecting portion for connecting the two at the lower left and lower ends of the inner glass with a rod, and the outer glass. The movable setting block is moved by comparing the temperature inside the cavity formed between the glass and the inner glass with the room temperature and the preset temperature specified in advance and the cavity temperature obtained from the sensor. It is characterized by comprising a control unit for instructing the inner glass to be opened and closed.

In the cavity heat utilization promotion system, when the room temperature is lower than the set temperature, when the cavity temperature becomes higher than the set temperature, the control unit is warmed in the cavity until the room temperature reaches the set temperature. It is characterized by giving instructions to take in the air into the room.

In the cavity heat utilization promotion system, when the room temperature is higher than the set temperature, when the cavity temperature becomes higher than the set temperature, the control unit controls the cavity until the cavity temperature becomes lower than the set temperature. It is characterized by instructing the air warmed by the air to be discharged to the outside of the room.

In the heat utilization promotion system of the cavity, the control unit measures the radiant heat in the room and fluctuates the set temperature.

In the heat utilization promotion system of the cavity, a fan is further provided in the ventilation path connecting the cavity, the room and the outside, and the control unit closes the outdoor side of the ventilation path when the air in the cavity is taken into the room. When the fan is instructed to flow air into the room and the air in the cavity is discharged to the outside, the fan is instructed to flow air to the outside by blocking the indoor side of the ventilation path. It is characterized by that.

The cavity heat utilization promotion system is characterized in that an electric switchgear provided with a slider for opening a ventilation gap in the inner glass is provided in the window frame of the opening.

In the heat utilization promotion system of the cavity, the electric switchgear is characterized in that a holding tool for connecting the inner glass and the slider is detachably provided with respect to the inner glass.

According to the present invention, the heat of the cavity formed in the opening of the building can be effectively utilized. For example, it is possible to easily grasp the timing of taking in the air warmed in the cavity into the room in the cold season.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. Those having the same function are designated by the same reference numerals, and the repeated description thereof may be omitted.

First, the cavity heat utilization promotion system of the present invention will be described. FIG. 1 is a diagram showing an outline of a cavity heat utilization promotion system. FIG. 2 is a diagram showing an inner glass installed in a cavity heat utilization promotion system.

As shown in FIG. 1A, the cavity heat utilization promotion system 100 is a system that improves the thermal efficiency of the room by utilizing the cavity 210 formed between the outer glass 200 and the inner glass 300, and is a system that improves the thermal efficiency of the room. It includes a rail 310 for moving the 300, a movable setting block 400, sensors 220 and 320 for controlling the temperature, a control unit 500, and the like.

The outer glass 200 is a flat glass that is fitted into a window frame provided at an opening of a building and is installed so as to be able to be closed or opened and closed, and serves as a boundary between indoors and outdoors. A plurality of outer glasses 200 may be arranged vertically and horizontally to form a curtain wall in which the building is covered with glass. Since the outer glass 200 is a general flat glass, for example, when the room temperature is higher than the outside air temperature in a cold season, heat flows out to the outside. Further, the vicinity of the outer glass 200 in the room becomes hot due to the heat of the sun.

The inner glass 300 is a sashless flat glass arranged on the indoor side of the outer glass 200. As the inner glass 300, low-emissivity double glazing or the like having a high heat insulating / heat insulating effect is used in order to reduce the influence of heat on the room. The inner glass 300 is not attached with a frame material or the like having a door roller around it, but may be provided with an airtightness by a sealing material or the like. A double skin is formed after securing a cavity 210 between the outer glass 200 and the inner glass 300.

The rail 310 is laid at the place where the inner glass 300 is installed. The inner glass 300 is sandwiched between the upper rail provided on the ceiling and the lower rail provided on the floor surface, and the inner glass 300 is slid and moved in the plane direction along the rail 310. In the upper rail, the inner glass 300 is not suspended but is held so that the inner glass 300 does not come off. In the lower rail, the load of the inner glass 300 is supported and the inner glass 300 is held so as not to come off.

When the inner glass 300 is fitted into the rail 310, the movable setting block 400 receives the load of the inner glass 300 and mounts the inner glass 300, and causes the inner glass 300 to travel along the rail 310. The movable setting block 400 is housed in the rail 310 in advance, and the inner glass 300 is detachably placed on the inner glass 300.

The cavity 210 is a hollow layer formed by the outer glass 200 and the inner glass 300, and is provided for storing solar heat. The temperature of the cavity 210 is likely to change due to the influence of heat outside the room through the outer glass 200, and the temperature change inside the room is suppressed by the inner glass 300.

As shown in FIG. 1 (b), when the double-skin structure is used, the air in the cavity 210 is warmed even when the room temperature is higher than the outside air temperature during the heating period, so that the heat outflow to the outside is suppressed. Further, as shown in FIG. 1 (c), when the temperature in the cavity 210 rises above room temperature, heat can be taken into the room.

The sensor 220 is a measuring means for acquiring various information such as temperature and humidity in the cavity 210, and transmits various information in the cavity 210 to the control unit 500. The sensor 320 is a measuring means for acquiring various information such as room temperature and radiant heat, and transmits various information in the room to the control unit 500.

The control unit 500 is a computer CPU (central processing unit) or the like, and controls a storage unit 510, an input unit 520, an output unit 530, a communication unit 540, and the like. The storage unit 510 is a memory, a magnetic disk, or the like (including a recording medium), and temporarily or long-term records various input information and result information calculated by the control unit 500. The input unit 520 is a mouse, a keyboard, or the like, and receives user's instructions and the like. The output unit 530 is a monitor, a printer, or the like, and displays result information. The communication unit 540 is a device that transmits and receives via a computer network, receives various information from the sensors 220 and 320, and transmits a drive command to the movable setting block 400.

The control unit 500 compares the room temperature with the preset temperature specified in advance and the cavity temperature acquired from the sensor 220 to notify the user that the inner glass 300 should be opened or closed, or informs the movable setting block 400 of the inner glass. It gives an instruction to open and close 300.

As shown in FIG. 2, the movable setting block 400 is arranged at two places, for example, the lower left end and the lower right end of the inner glass 300. The movable setting block 400 at the lower left end and the movable setting block 400 at the lower right end are connected by a rod 420 or the like, and an interval is maintained so as to be arranged at both ends of the inner glass 300. As the rod 420, one obtained by molding a resin or the like into a rod shape or a plate shape may be used.

When the heat insulating property of the inner glass 300 is improved, the heat accumulated in the cavity 210 is difficult to be taken into the room. Therefore, the inner glass 300 may be opened to directly take in the air in the cavity 210 into the room. The opening and closing of the inner glass 300 may be manually performed by the user, or may be automatically performed by the control unit 500 driving the door roller 410 of the movable setting block 400.

In the case of flat glass with a frame material, the frame material is attached around the flat glass in advance at a factory or the like and then carried to the site, so even if you try to adjust the inclination of the flat glass after fitting it into the rail 310, the flat glass It is difficult if it is large and heavy. In the case of the inner glass 300, only the flat glass needs to be brought into the site, and only the flat glass can be attached to and detached from the movable setting block 400 to adjust the inclination and the like.

Next, the movable setting block used in the cavity heat utilization promotion system will be described. FIG. 3 is a diagram showing a movable setting block that slides and moves the inner glass installed in the heat utilization promotion system of the cavity. FIG. 4 is a diagram showing attachment / detachment of the inner glass installed in the heat utilization promotion system of the cavity to / from the movable setting block.

The door roller 410 is a wheel that rotates to run in the rail 310. The rod 420 is a member that connects adjacent movable setting blocks 400 to each other. The cushioning material 430 receives the inner glass 300 when it is placed and cushions the impact, and also absorbs vibrations and the like generated when the movable setting block 400 is run. When the inner glass 300 is placed, the support material 440 sandwiches the lower portion of the inner glass 300 from the front and rear and supports the inner glass 300 so as not to come off. The connecting portion 450 is a portion for connecting the rod 420, and for example, a hole for hooking the tip of the hook-shaped rod 420 may be provided.

As shown in FIG. 4A, when the inner glass 300 is fitted into the rail 310, the lower surface of the inner glass 300 rests on the cushioning material 430, and the lower part of the inner glass 300 is the front surface and the rear surface (left and right in the figure). The side) is sandwiched between the support members 440. For example, a hemispherical or the like may be provided on the inner surface of the support material 440 with a resin or the like and may be pressed by elasticity. Further, the movable setting block 400 may be pressed by a protrusion so as not to protrude from the rail 310.

As shown in FIG. 4B, if the inner glass 300 is tilted when placed on the movable setting block 400, the height of the inner glass 300 may be adjusted by the cushioning material 430. As the cushioning material 430, a plate-shaped resin or the like may be placed interchangeably, and the thickness of one cushioning material 430 may be changed, or a plurality of cushioning materials 430 and 430a may be stacked and adjusted according to the number of sheets. ..

Next, a case where heat is taken into the room by the heat utilization promotion system of the cavity will be described. FIG. 5 is a flowchart showing the flow of the heat acquisition mode of the heat utilization promotion system of the cavity. FIG. 6 is a diagram illustrating a heat acquisition mode of the heat utilization promotion system of the cavity. FIG. 7 is a diagram showing a case where a ventilation path is used in the heat acquisition mode of the heat utilization promotion system of the cavity.

As shown in FIG. 5, in the heating period, the control unit 500 sets the set temperature Td, the adjustment value m, and the like first in the initial setting step S100, and sets the room temperature Ti, the cavity temperature Tc, and the like in real time or periodically. Processes such as the information acquisition step S110 to be acquired and the steps S120 to S150 for continuing or changing the current mode according to the conditions are executed, and the process is repeated from the information acquisition step S110.

The set temperature Td is a threshold value set as a boundary value for changing the condition, and is compared with the room temperature Ti and the cavity temperature Tc. The user's input is acquired from the input unit 520 and stored in the storage unit 510.

The adjustment value m is the set temperature so that the set temperature Td is adjusted in consideration of the radiant heat in the room, and the mode change is not frequently repeated when the room temperature Ti or the cavity temperature Tc fluctuates slightly near the set temperature Td. It is used as a buffer for adjusting Td.

When the room temperature Ti is lower than the set temperature Td and the cavity temperature Tc becomes higher than the set temperature Td, the control unit 500 takes in the air warmed by the cavity 210 until the room temperature Ti reaches the set temperature Td. Just give instructions.

In step S110, information such as room temperature Ti measured by the sensor 320 and the cavity temperature Tc measured by the sensor 220 is acquired via the communication unit 540 and stored in the storage unit 510 together with the time information.

In step S120, it is confirmed whether the mode is the standby mode or the heat acquisition mode, and if it is the standby mode, the process proceeds to step S130a, and if it is the heat acquisition mode, the process proceeds to step S130b. The mode may be, for example, given to the storage unit 510 as a flag to determine the state.

As shown in FIG. 6A, the standby mode is a state in which the inner glass 300 is closed to partition the cavity 210, and the control unit 500 issues a drive command to the movable setting block 400 to close the inner glass 300. Alternatively, the output unit 530 may be displayed to urge the user to close the inner glass 300.

As shown in FIG. 6B, the heat acquisition mode is a state in which the inner glass 300 is opened to take in the air warmed in the cavity 210 into the room, and the control unit 500 puts the inner glass 300 in the movable setting block 400. A drive command may be issued to open the inner glass 300, or the output unit 530 may be displayed to urge the user to open the inner glass 300.

Further, an open / close sensor may be installed to acquire the open / closed state of the inner glass 300, and if the inner glass 300 is closed, it may be determined to be in the standby mode, and if the inner glass 300 is open, it may be determined to be in the heat acquisition mode.

In step S130a in the standby mode, the room temperature Ti and the set temperature Td are compared, and if the room temperature Ti is equal to or less than the set temperature Td, the process proceeds to step S140a, and if the room temperature Ti is higher than the set temperature Td, the standby mode is continued (step S150b). ). The set temperature Td is the temperature adjusted by the adjustment value m.

In step S140a, the cavity temperature Tc and the set temperature Td are compared, and if the cavity temperature Tc is equal to or higher than the set temperature Td, the heat acquisition mode is changed (step S150a), and if the cavity temperature Tc is lower than the set temperature Td, the standby mode is changed. (Step S150b). The set temperature Td may be different between step S130a and step S140a.

In step S130b in the heat acquisition mode, the room temperature Ti and the set temperature Td are compared, and if the room temperature Ti is higher than the set temperature Td, the mode is changed to the standby mode (step S150d), and if the room temperature Ti is the set temperature Td or less, step S140b. Proceed to. The set temperature Td is the temperature adjusted by the adjustment value m.

In step S140b, the cavity temperature Tc and the set temperature Td are compared, and if the cavity temperature Tc is lower than the set temperature Td, the standby mode is changed (step S150d). (Step S150c). The set temperature Td may be different between step S130b and step S140b.

Further, when the room temperature Ti is higher than the set temperature Td, the control unit 500 blows the air warmed in the cavity 210 until the cavity temperature Tc becomes lower than the set temperature Td when the cavity temperature Tc becomes higher than the set temperature Td. You may give an instruction to discharge it to the outside of the room.

As shown in FIG. 7A, a ventilation passage 600 leading to the outside of the room is provided on the ceiling or the like of the room, and a ventilation hole is provided in the cavity 210 and the room. Then, a fan 610 is installed in the ventilation path 600 to enable forced air flow. Further, the ventilation passage 600 is also provided with a valve 620 for closing the passage to the outside and a valve 620a for closing the passage to the inside of the room.

In the standby mode, the inside of the cavity 210 is sealed by closing the valve 620 and the valve 620a. When the air in the cavity 210 warms up and becomes higher than the set temperature Td, the control unit 500 opens the valve 620 and drives the fan 610 so that the warm air in the cavity 210 is discharged to the outside. good.

FIG. 9 is a diagram illustrating a heat removal mode of the heat utilization promotion system of the cavity. FIG. 10 is a diagram showing a case where a ventilation path is used in the heat removal mode of the heat utilization promotion system of the cavity.

As shown in FIG. 8, in the cooling period, the control unit 500 sets the set temperature Td, the adjustment value m, and the like first in the initial setting step S200, and sets the room temperature Ti, the cavity temperature Tc, and the like in real time or periodically. Processes such as the information acquisition step S210 to be acquired and the steps S220 to S250 for continuing or changing the current mode according to the conditions are executed, and the process is repeated from the information acquisition step S210.

When the room temperature Ti is higher than the set temperature Td and the cavity temperature Tc is higher than the set temperature Td, the control unit 500 sends the air warmed by the cavity 210 to the outside until the cavity temperature Tc becomes lower than the set temperature Td. You just have to give an instruction to discharge it.

In step S210, information such as room temperature Ti measured by the sensor 320 and the cavity temperature Tc measured by the sensor 220 is acquired via the communication unit 540 and stored in the storage unit 510 together with the time information.

In step S220, it is confirmed whether the mode is the standby mode or the heat removal mode, and if it is the standby mode, the process proceeds to step S230a, and if it is the heat removal mode, the process proceeds to step S230b. The mode may be, for example, given to the storage unit 510 as a flag to determine the state.

As shown in FIG. 9, the standby mode is a state in which the inner glass 300 is closed to partition the cavity 210, and the control unit 500 may issue a drive command to the movable setting block 400 to close the inner glass 300. , The output unit 530 may be displayed to urge the user to close the inner glass 300. Further, the heat removal mode is a state in which the air warmed in the cavity 210 is discharged to the outside of the room while the inner glass 300 is closed.

In step S230a in the standby mode, the room temperature Ti and the set temperature Td are compared, and if the room temperature Ti is equal to or higher than the set temperature Td, the heat removal mode is changed (step S250b), and if the room temperature Ti is lower than the set temperature Td, step S240a. Proceed to. The set temperature Td is the temperature adjusted by the adjustment value m.

In step S240a, the cavity temperature Tc and the set temperature Td are compared, and if the cavity temperature Tc is equal to or higher than the set temperature Td, the heat removal mode is changed (step S250b), and if the cavity temperature Tc is lower than the set temperature Td, the standby mode is changed. (Step S250a). The set temperature Td may be different between step S230a and step S240a.

In step S230b in the heat removal mode, the room temperature Ti and the set temperature Td are compared, and if the room temperature Ti is lower than the set temperature Td, the process proceeds to step S240b, and if the room temperature Ti is equal to or higher than the set temperature Td, the heat removal mode is continued ( Step S250d).

(Step S250d). The set temperature Td may be different between step S230b and step S240b.

In the standby mode, as shown in FIG. 10A, the inside of the cavity 210 is sealed by closing the valve 620 and the valve 620a. When the air in the cavity 210 warms up and becomes higher than the set temperature Td, the control unit 500 opens the valve 620 and drives the fan 610 so that the warm air in the cavity 210 is discharged to the outside. good.

The user may instruct the operation of the fan 610 and the valves 620 and 620a from the input unit 520. For example, it is possible to ventilate the room by opening the valves 620 and 620a to connect the inside and the outside.

Next, in the cavity heat utilization promotion system of the present invention, control for automatically acquiring and removing heat will be described. FIG. 11 is a diagram showing a case where an electric switchgear is provided in the heat utilization promotion system of the cavity. FIG. 12 is a plan view showing an electric switchgear. FIG. 13 is a diagram showing switching of the operation mode of the electric switchgear. FIG. 14 is a flowchart showing the flow of the heat acquisition mode when the electric switchgear is used. FIG. 15 is a flowchart showing the flow of the heat removal mode when the electric switchgear is used. FIG. 16 is a diagram showing a case where the electric switchgear is provided up and down.

As shown in FIG. 11A, the cavity heat utilization promotion system 100a is provided with an electric switchgear 700 for opening and closing the inner glass 300. The electric switchgear 700, for example, takes in the air (heat) warmed in the cavity 210 during the heating period into the room, or discharges the air (heat) warmed in the cavity 210 during the cooling period to the outside. When the cold air in the room is supplied into the cavity 210, the inner glass 300 which is normally closed is slightly opened.

It is not necessary to fully open the inner glass 300 when ventilating between the inside of the cavity 210 and the room, and it is sufficient if there is a slight gap (for example, about 1 to 5 cm). If the air pressure in the cavity 210 is higher than that in the room, air enters the room, and if the air pressure in the cavity 210 is lower than that in the room, air is sent into the cavity 210. Therefore, at least one of the plurality of inner glasses 300 may be slid and moved in the left-right direction so as to have a sufficient gap for ventilation.

For example, the electric switchgear 700 is attached to the lower side (outside of the rail) of the right end or the left end of the window frame of the opening, and the rightmost or left inner glass 300 is slightly moved. As shown in FIG. 11B, the slider 710 of the electric switchgear 700 is operated so that the vertical frame 340 of the inner glass 300 is in contact with the vertical frame 330 of the opening during the closing operation, and the inner glass 300 is operated during the opening operation. The slider 710 of the electric switchgear 700 is operated so that the vertical frame 340 of the above is separated from the vertical frame 330 of the opening.

As shown in FIG. 12, in the electric switchgear 700, a main body having a drive unit is fixed to a window frame, and a slider 710 that is relatively movable with respect to the main body is connected to an inner glass 300. For example, the slider 710 may be movable by expanding and contracting the shaft body from the main body. Further, the vertical frame 340 of the inner glass 300 is continuously provided with a handle 350 projecting to the indoor side, and the slider 710 may be connected by attaching a detachable holding tool 720 to the vertical frame 340.

The electric switchgear 700 receives a command signal from the control unit, an operation signal from the remote controller, or the like, and the drive unit automatically operates the slider 710. In addition, the user may manually open and close the inner glass 300 due to notification from the control unit, usage status, maintenance necessity, or the like. When the electric switchgear 700 and the inner glass 300 are connected, the free opening and closing of the inner glass 300 is restricted, but by disconnecting the connection, the inner glass 300 is fully opened and the inside of the cavity 210 is cleaned. Will be easier.

For example, as shown in FIG. 13A, in the electric mode, the holding tool 720 is fitted into the vertical frame 340 of the inner glass 300 to be connected to the slider 710, and manually as shown in FIG. 13B. In the mode, the holding tool 720 is removed from the vertical frame 340 of the inner glass 300 to release the connection with the slider 710.

As shown in FIG. 14, the control unit 500a switches the heat acquisition mode in the heating period, but when the control unit 500a is used in the electric mode, the control unit 500a changes from the standby mode to the heat acquisition mode in step S150a. The electric switchgear 700 may instruct the inner glass 300 to be opened (step S160a).

As shown in FIG. 16, if the electric switchgear 700 is attached only to the lower side of the opening, the upper part of the inner glass 300 may be caught and may not move smoothly. Therefore, the electric switchgear 700a is also attached to the upper side of the opening. May be attached. Further, the electric switchgear 700 may be provided between the inner glass 300 on the far right and the inner glass 300a adjacent thereto, and the inner glass 300 or 300a may be moved to any position.

According to the present invention, the heat of the cavity formed in the opening of the building can be effectively utilized. For example, it is possible to easily grasp the timing of taking in the air warmed in the cavity into the room in the cold season.

Although examples of the present invention have been described above, the present invention is not limited thereto. The control unit 500 may omit some steps or add other steps if it can achieve the same effect as the heat utilization promotion system 100 of the cavity.

Further, for example, a store with a large number of people coming and going, such as a convenience store, is a building with a large air conditioning load and poor thermal efficiency. Even if the inside of the store is cooled by cooling in the hot season, if the doorway is opened and closed frequently, the outside air can easily enter the store and the cooling effect is lost. Therefore, the air conditioning load of the entire store can be reduced by dividing the store into two spaces with inner glass and allowing one room to function as a double-skin cavity.
