The hollow layer 250 serves as a passive space in a natural fashion. The internal air environment is controlled by controlling the inflow or outflow of airflow, and the degree of the airflow using the first ventilator 240 and the second ventilator 242.

The buffer zone 150 serves as an active space according to the facility-type addable method, and performs conditioning of the internal air to control the temperature, humidity, cleanliness, and the like of the internal air. The makeup box 400 may be provided at an upper side and / or a lower side, such that a cooling installation, a heating installation, a filter, a humidification installation, a dehumidification installation, and a heat exchanger may be installed. The user may condition the air in the buffer zone 150 by actively performing one or more functions of cooling, heating, filtering, humidification, dehumidification, and heat exchange using a facility installed in the makeup box 400.

In addition, although the makeup box is illustrated as being installed above and / or below in FIG. 4, it may be installed on the left and / or right side of the hybrid facade system according to the embodiment.

In addition, a vane 450 may be installed between the first ventilation unit 240 and the second ventilation unit 242 to guide the flow direction of the airflow.

By adjusting the transmittance or shielding rate through two-step shading using the first shading unit 230 and the second shading unit 500, an adjustable range according to a user's preference may be expanded. For example, if you want to increase the room temperature but want to prevent glare, that is, if you want to allow inflow of solar radiation but want to block the inflow of sunlight, the first shading unit 230 weakens the shading degree and buffer zone 150. ) To allow both solar radiation and sunshine to flow, and the second light shielding part 500 may block the inflow of sunlight to the indoor side by strengthening the degree of light shielding. At this time, the air inside the buffer zone 150 and the hollow layer 250 warms up due to the solar radiation introduced to the second light blocking part 500, while the indoor temperature is increased by the second light blocking part 500. As sunlight does not flow in, it does not feel visual discomfort caused by glare.

As such, by using the first light blocking part 230 and the second light blocking part 500, the control variable is increased so that the user can adjust the indoor environment in accordance with preference.

In addition, the hybrid facade system according to the present invention has the advantages of the existing double skin system. When viewed based on only the inner window 100 and the outer window 200 in one aspect it can be seen as a first double skin system having a buffer zone 150 therebetween. In another aspect, the first window 210 and the second window 220 constituting the outer window 200 may be viewed as a second double skin system having a hollow layer 250 therebetween.

The system mode for indoor environment control in this basic double skin system is shown in FIG. 6. FIG. 6 shows airflow in system mode of a double skin system.

In the position of the first double skin system, both skins shown in FIG. 6 are the inner window 100 and the outer window 200, and the hollow layer is the buffer zone 150. And from the standpoint of the second double skin system, both skins shown in FIG. 6 are the first window 210 and the second window 220, the hollow layer is a hollow layer 250.

Ten system modes may occur in the hollow layer as shown in FIG. 6. Mode 0 and mode 1 represent an indoor circulation mode, mode 3 and mode 4 represent an outdoor circulation mode, and modes 5-8 represent the diagonal airflow mode. In addition, system modes such as mode 9 or mode 10 are shown.

Each of these system modes may be equally applicable to the first double skin system or the second double skin system. Therefore, the control method and system according to such a system mode are equally applicable to the present invention.

In the present invention, an additional system mode for heating or cooling may be applied. This will be described below with reference to the drawings. In the drawings, a hybrid facade system is simplified for the convenience of understanding and description of the invention.

Figure 7a is a view showing the airflow in the heating mode of the basic double skin system, Figure 7b is a view showing the airflow in the heating mode of the hybrid facade system according to an embodiment of the present invention, Figure 7c is a view of the present invention 2 shows a night insulation mode of the hybrid facade system according to the embodiment.

Referring to FIG. 7A, in the heating mode of the basic double skin system, all of the outdoor side vents of the double skin are closed, and all of the indoor side vents are opened to allow indoor air to flow back into the interior of the building through the hollow layer 700. There is an air circulation to repeat.

Referring to FIG. 7B, the hybrid facade system according to the present invention similarly closes the inner window 100 first, so that the air in the buffer zone 150 flows back into the buffer zone 150 through the hollow layer 250. It can be seen that the air circulation is repeated to repeat the process. When the environment inside the buffer zone 150 is adjusted to a desired level by the air circulation, the air inside the buffer zone 150 is introduced into the room by opening the inner window 100 so that the indoor environment can be quickly and smoothly controlled. .

Referring to FIG. 7C, a night insulation mode in a hybrid facade system is shown. The night insulation mode is a high insulation mode, which closes the inner window 100, closes all vents of the outer window, and also completely shields the first light shield 230 in the hollow layer 250.

Through this, by obtaining the thermal insulation effect of the multiple windows by the outdoor window, the first shading unit 230, the indoor window and the inner window 100 of the outer window, it is possible to maximize the thermal insulation effect. In addition, since the high insulation effect can be obtained, there is an effect of reducing the possibility of condensation in the building interior.

Figure 8a is a view showing the airflow in the cooling mode of the basic double skin system, Figure 8b is a view showing the airflow in the cooling mode of the hybrid facade system according to an embodiment of the present invention.

Referring to FIG. 8A, in the cooling mode of the basic double skin system, the interior air vents of the double skin are all closed, and the outdoor air vents are all open, so that outdoor air flows back out of the building through the hollow layer 800. An air circulation repeating is shown. At this time, radiant heat transfer can be blocked and convective heat transfer between indoors and outdoors does not occur. However, during this process, the inside of the hollow layer 800 is overheated due to the outdoor temperature, and heat transfer occurs to the interior of the building.

Referring to FIG. 8B, in the cooling mode of the hybrid facade system according to the present invention, due to the dual structure of the buffer zone 150 and the hollow layer 250, heat is transferred from the hollow layer 250 to the buffer zone 150. Blocking is also possible. That is, there is an effect of blocking the heat transfer double, the heat insulation effect is maximized, there is an advantage that the transfer of convection heat is blocked.

9 and 10 are views showing the airflow in the ventilation mode of the hybrid facade system according to an embodiment of the present invention.

Referring to FIG. 9, in the hybrid facade system according to the present invention, the outside air is introduced into the buffer zone 150, the hollow layer 250, and the interior of a building by opening the inner windows and opening all the ventilation holes of the outer windows. Can be spilled outdoors.

In addition, when the outside temperature is comfortable in summer, but the amount of insolation is large, the outside air is opened by opening the inner windows and opening all the ventilation holes of the outer windows, as shown in FIG. 10, and the buffer zone 150, the hollow floor 250, and the interior of the building. It can be introduced into the indoor air can be discharged to the outdoor. However, the first light blocking portion 230 inside the hollow layer is completely shielded so that solar radiation does not flow into the interior.

Hereinafter, a method of controlling indoor air of a building by driving a hybrid facade system according to the present invention will be described. Hybrid facade system according to the present invention includes a sensing unit for measuring the state of the outside air and indoor air, a control unit for calculating the operation of the outer window and the inner window according to the value measured in the sensing unit and a predetermined condition, According to the calculation result, it may further include a driving unit for driving at least one of the inner window and the outer window can automatically control the indoor air of the building.

11 is a flowchart illustrating a method for controlling indoor air of a building in a hybrid facade system according to an embodiment of the present invention.

In step 1100, the sensing unit measures the state of the outside air and indoor air. Here, the interior may be in a buffer zone or in a living room of a building. The measured outdoor and indoor air conditions include outdoor temperature, outdoor humidity, direct solar radiation, scattered solar radiation, outdoor illuminance / luminance distribution, wind speed, room temperature, indoor humidity, and indoor illuminance / luminance distribution.

The sensing unit may be installed indoors, outdoors, and / or windows of a building. Measurement sensors for outdoor temperature, outdoor humidity, insolation, outdoor illuminance and luminance distribution, rainfall, and wind speed are installed on the outdoor side or window of the building, and indoor temperature, indoor humidity, indoor illuminance and luminance distribution, IAQ (Indoor Air Quality) Can be installed on the interior side of the building.

In step 1110, the controller calculates whether the outer window and the inner window are driven according to the value measured in step 1100 and a preset condition. The set condition may be season (summer / winter / spring autumn), time zone (day / night), target space (hollow layer (passive) / buffer zone (active)), or the like.

For example, if the measured value corresponds to a summer day and the setting condition is heat shielding, the outside air is introduced and treated in the hollow layer, and then flowed out to treat the outside air (see FIG. 8B). At this time, the first and second windows of the outer window are opened, and the inner window is closed. The buffer zone regulates indoor air through conditioning, which reduces the energy consumed by the conditioning.

If the measured value corresponds to the spring, fall or winter day and the indoor air is muddy, the setting condition is the introduction of outdoor air.The outdoor air is introduced and controlled first in the hollow layer and sent to the buffer zone. Condition in such a condition that it can flow in. First, only the first window of the outer window is opened, and when the first adjustment is completed, the first window is closed and the second window is opened, and then the inner window is opened when conditioning is completed.

If the measured value corresponds to the summer night and the setting condition is indoor air leakage, send the air of the living room to the buffer zone to replace some with the outside air, and use the suction effect of the outside window to allow the air of the buffer zone to flow out to the outdoors. do. First, the inner window is opened, and when the replacement is completed, the outer window is opened.

If the measured value corresponds to winter or night and the set condition is adiabatic, the outside windows are closed and conditioned through the buffer zone to recirculate the indoor air or only the first windows of the outside windows are opened and the second windows are opened Condition through layers and / or buffer zones. Alternatively, all vents of the outer windows as well as the inner windows are closed, and the first shading part in the outer windows is in an all shut mode (see FIG. 7C). Through this, by obtaining the insulation effect of the multiple windows by the outdoor window, the primary lighter, the indoor window and the inner window of the outer window, it is possible to maximize the insulation effect.

Here, the set condition may be implemented in the form of an operation mode corresponding to the user's operation command. The driving mode may be classified into a visual comfort mode, a thermal comfort mode, an automatic driving mode, an energy saving mode, an occupant selection mode, a night mode, and the like. The user may select a plurality of driving modes collectively so as to be classified according to conditions (for example, by time zone, indoor temperature, indoor humidity, etc.) to individually operate the designated operation mode according to a matching condition.

For example, when it is set to the visual comfort mode, glare is prevented by controlling the inflow of sunlight into the room by adjusting the degree of shielding of the first shielding portion in the hollow layer and / or the second shielding portion in the buffer zone. If the thermal comfort mode is set, heat shielding may be required during summer daytime or heat insulation during winter or at night, and the inside and outside windows are controlled to handle outside air, recycle indoor air, and make-up installed in the buffer zone. Condition the internal air using a box. When set to energy saving mode, the indoor air is kept to a minimum to minimize energy consumption. Do not let the outside air and sunshine enter the room in summer, and let the sunshine flow into the room without winter air. In the occupant selection mode, the inner and outer windows are driven according to the contents selected by the occupants in the interior of the building.

In operation 1120, the driver drives one or more of an outer window and an inner window according to the result of the operation in operation 1110. The outer window may include a ventilation part and a first light blocking part, and the outer window may be driven by performing a predetermined operation of at least one of the ventilation part and the first light blocking part. In the case of the ventilation unit, the opening degree can be adjusted by rotating the louver of the ventilation damper so that the ventilation opening is opened or closed.In the case of the first shading unit, the degree of shading can be adjusted by changing the inclination, shielding area, etc. of the slats and louvers of the shading device. have. The inner window can be driven to open and close the air flow in the buffer zone and out the air in the living room.
