The present invention relates to a double skin system, and more particularly to a double skin system of a building and a control method thereof.

Although windows provide natural light and view, they can also cause visual discomfort due to excessive heating and heating loads, thermal discomfort due to solar radiation, and glare. In order to overcome this problem, a double envelope was introduced into a building from early on, and the double envelope is generally composed of an outer window facing the outdoors, an inner window facing the interior, and a hollow layer formed therebetween. Openings and ventilation dampers are provided in the outer and inner windows to control the opening ratio of the openings, and louvers or blinds are provided in the hollow layer to control the inflow of sunshine and solar radiation. Generally, the opening is divided into the upper part and the lower part of the outer window.

The general control method of the double skin is that the heater closes all the openings of the outer and inner windows and the solar energy absorbed and emitted by the louver or blind increases the temperature of the hollow layer to reduce heat loss from indoors to outdoors. In the air conditioner, the louver or blind of the hollow layer absorbs solar energy and releases it from the hollow layer, and thermal buoyancy is formed in the hollow layer. When the upper and lower openings of the outer window are opened, hot air is opened by the thermal buoyancy in the hollow layer. And cool air is introduced from the lower opening to prevent solar energy from entering the room.

However, the conventional control method has a problem in that it is not based on a dynamic model of the system, but depends on simple rules. Since the building and the envelope of the building have inertia like a moving plane or a car, the control based on the current state does not reflect the change of the system, so there is a limitation that the control is not performed at the optimal state.

In addition, because the building envelope is related to all of the heat, light, sound, and air environments, controlling the building to favor only one side of the building is likely to cause a rather unfavorable condition on the other side.

The double skin system should be controlled differently according to outdoor and indoor variables, but there are many cases where there is no occupant, or even if there are occupants, the correct control state cannot be determined.

In addition, even if the occupants can determine the correct control state, if time passes without immediate control according to the needs of the occupants, the control state, which was determined to be correct at the characteristic time point, is changed to an unavoidable state. There is a problem. In such cases, the problem is that the double skin system may cause excessive energy waste and create an unpleasant indoor environment.

And duplicate description thereof will be omitted.

1 is a flow chart showing a control method of a double envelope system according to an embodiment of the present invention.

The present invention is to improve the energy saving and indoor comfort by controlling the double skin system of the building in real time in consideration of the indoor and outdoor environmental conditions and building user preferences.

In the present invention, a double skin system of a building to be controlled is a system that has been conventionally designed and applied in various forms at home and abroad, and is basically formed between two skins, ventilation parts formed on each skin, between the skins, or on the outdoor side. It consists of a light shielding part. Among them, the ventilation unit controls indoor ventilation amount, outdoor air-conditioning air conditioning, etc., and the shading part is a component that controls whether the solar inflow amount is indoor and natural light.

That is, the double skin system to which the control method according to the present invention is applied is based on a first skin which is installed to constitute a building skin, a second skin which is spaced apart from the first skin by a predetermined interval, and installed on the outdoor side rather than the first skin. In addition, by controlling the airflow and solar radiation flowing in and out of the interior and exterior in the hollow layer, which is a space between the first envelope and the second envelope, it is possible to create an indoor environment superior to a building having a single envelope.

The first shell and the second shell may be provided with a fixed window, a sliding window, a closed window, etc. within a range apparent to those skilled in the art, and the following embodiments will be described by using the fixed window as an example. However, it is a matter of course that the windows installed on the first shell and the second shell of the present invention are not necessarily limited to the fixed window. The fixed window may be configured to be closed automatically, for this purpose the drive motor may be coupled to the opening and closing mechanism of the fixed window.

Ventilation dampers are provided as upper and lower portions of the first shell and the second shell as ventilation units. That is, a first ventilation damper is installed on the upper and lower portions of the first outer shell, and a second ventilation damper is provided on the upper and lower portions of the second outer shell, and each of them can be controlled separately. As the ventilation unit of the present invention, a ventilation port, an electric ventilation window (sliding, opening and closing), a ventilation damper, a ventilation duct and the like may be installed within a range apparent to those skilled in the art. However, the ventilation unit of the present invention is not necessarily limited to the ventilation damper.

The ventilation damper can be opened and closed, and the driving motor is coupled to the ventilation damper when controlling the driving as in the present invention. By installing the ventilation openings on the upper and lower portions of the outer shell, the natural air circulation of the air flow introduced from the lower portion is heated in the hollow layer and flows out to the upper portion by buoyancy.

The louver is provided on the outdoor side of the second shell or the hollow layer between the first shell and the second shell. The light-shielding portion of the present invention may be provided with louvers, blinds, curtains, roll screens, etc. which are components that function to block the sun within a range apparent to those skilled in the art. In the following embodiments, the louvers will be described as an example. However, the light shielding portion of the present invention is not necessarily limited to the louver, of course.

Since solar radiation contains light and heat, both light and heat can be blocked when the louver is installed on the outdoor side, and light is blocked when the louver is installed in the hollow layer between the first and second skins, but the heat is double skinned. It will be introduced into the hollow layer of the, by adjusting the ventilation dampers installed in each shell can be transferred to the indoor or outdoor heat introduced into the hollow layer.

When the louver is installed on the indoor side, light is blocked but it is difficult to block heat from entering the room. Therefore, in order to control the double skin in consideration of the cooling and heating load of the room, the louver is installed on the outdoor side or the hollow layer. desirable. On the other hand, the louver may be installed on the indoor side of the first sheath, and may be installed on the indoor side of the first sheath even when there is no second sheath.

When the louver is used as the light blocking portion, the shading degree is adjusted according to the inclination angle of the louver. That is, the inclination angle of the louver is changed to adjust the shading degree of the louver, and in the case of automatically controlling the operation of the louver by the controller as in the present invention, the driving motor is coupled to the louver. It will be apparent to those skilled in the art that the driving motor coupled to each of the above-mentioned ventilation dampers and the driving motor coupled to the louver may be separately controlled by receiving signals from the control unit.

The control unit is installed to receive the data on the environmental variables of the indoor and outdoor, and to determine the optimum control state so that the indoor environment is controlled by controlling the operation of the control unit of the double skin, that is, the ventilation damper and the louver. The control unit should be connected to the input means such as sensors, user input devices, etc., and should also be connected to the drive motor coupled to the ventilation damper and louver.

When the control unit is formed in the form of a microprocessor, a computer system equipped with the same may be installed in a building, and a control system having a double skin can be configured by connecting an input unit, a ventilation damper, and a louver to the computer system. As will be described later, when the control unit is connected through a network, the control of the double skin system is possible not only when the user is occupied but also outside the building. In addition, in accessing the control unit through a network, setting an appropriate authority scheme for each user may prevent a control conflict between users.

The controller is set to a specific operation mode among a plurality of preset operation modes. Since buildings are inhabited spaces, both the comfort and energy savings of the occupants should be taken into consideration. Therefore, the weights of control variables such as comfort mode and energy saving mode should be weighted according to the control purpose rather than a single reference value for optimal control of the double skin. It is good to make the control according to the operation mode that is given.

In order to control the double skin system of a building including such a component, first, an outside temperature, insolation, and an indoor temperature are measured, a PMV is measured or calculated, and a heating / cooling load of the building is calculated (100). Of course, if necessary, it is good to measure not only the outside temperature but also the outside conditions such as humidity, wind direction, and wind speed.

The load to be removed by air conditioning and heating in the building for a certain time horizon from the outside temperature, insolation, and room temperature is calculated, and it is possible to determine whether to operate the double-shell system ventilation damper or louver to remove the heating and cooling load. have. In addition, the indoor illuminance and the surface luminance of the room are measured or calculated based on the measured value. PMV can be calculated from indoor environment information or measured using a measuring device, and becomes a reference value for controlling the indoor environment of a building to be formed in a comfortable range.

Of course, for more precise control, it is recommended to receive information on various environmental variables. For this purpose, the perforation state, the fragrance of the building, the transmittance of the glass constituting the double skin, the absorption rate of the material constituting the louver, and the area of the building's interior Data about the height, height, and reflectance of the interior finish of the building.

Each input value is used to more accurately calculate various values for determining the state of the double skin system and the heating and cooling load of the building, and environmental variables not specified herein may be applied to the present invention within a range apparent to those skilled in the art. Of course, it can be included in the input value.

Corresponding to each input value, various sensors are installed at the corresponding positions in the double skin system. The outside air temperature, outside air humidity, wind direction, wind speed, and solar radiation measuring sensors are respectively installed on the outdoor side of the second envelope, and the indoor temperature measuring sensor is installed on the indoor side of the first envelope, and the controller controls the double envelope system through a network as described below. In the case of control, a signal corresponding to the input value measured from the sensor is transmitted through the network.

Next, the required heating and cooling energy and the required ventilation amount of the building is calculated in response to the operation mode set by the controller (110). In the previous step 100, the heating and cooling load was calculated based on the indoor environment reference value, but the priority of the indoor environment reference value may vary according to the operation mode set in the controller.

For example, in the comfortable mode, air conditioning, ventilation and ventilation are performed simultaneously to create an indoor environment in the temperature, humidity, and carbon dioxide range where the building user feels comfortable, but in the energy saving mode, the indoor environment is too hot or too cold to not affect the building. To the extent it is possible to create an indoor environment irrelevant to the user's comfort.

In other words, after calculating the heating and cooling load from the input value of the indoor and outdoor environmental variables, instead of operating each component of the double skin system, it calculates the amount of heating and cooling energy and ventilation as necessary by reflecting the operation mode set in the control unit. As a result, the double skin system can be controlled according to the user's preference reflected in the form of the driving mode as well as the indoor and outdoor environmental variables.

The operation mode that can be set in the control unit is set based on the user's preference of the building, and includes visual comfort mode, thermal comfort mode, automatic driving mode, energy saving mode, occupant selection mode, and night mode.

On the other hand, if the heating or ventilation is performed by a heating and cooling system such as a heating ventilating air-conditioning (HVAC) system in a building where a double skin system is installed, the required heating / heating energy or the required ventilation amount to be supplied by the double skin system is a heating / heating system. Calculate except the value supplied by. In this case, the double skin system acts as an auxiliary system with the air conditioning system as the main system.

Next, the inclination angle of the louver, the opening and closing degree of the first ventilation damper and the second ventilation damper is calculated (120). This is a calculation process performed in the control unit. The required heating and cooling energy and the required ventilation amount are different for each operation mode, and if the heating and cooling system such as the HVAC system is installed in the building, the double skin system is controlled as an auxiliary system. Depending on the operation mode and the building situation, the calculated value will vary.

On the other hand, if the area where the double skin system is installed is changed and the comfort range, energy saving standard, and occupant's preference of the building user are changed, the standard values of the operation modes stored in the control unit are changed, a new operation mode is added or unnecessary. The control of the double skin system according to the present invention may be achieved by removing the operation mode.

The calculation of the required heating and cooling energy of the building and the required ventilation amount 110 and the calculation of the opening and closing degree of the louver and the ventilation damper are all performed by the controller, and the controller may be formed in the form of a microprocessor. When the control unit is implemented in a computer system, the computer system should be connected to sensors such as input means, a ventilation damper to be controlled, and a drive motor coupled to the louver.

In order to introduce natural light using the double skin system such as visual comfort mode among the operation modes stored in the controller, the illumination level of the room is measured, and the illumination level of the room is calculated to adjust the shading degree of the louver. In addition, the control unit calculates the luminance of the interior surface of the building or receives an input value from the sensor, and as a result, determines the visual comfort of the occupants.

That is, in the step of measuring the outside air temperature, outside air humidity, wind direction, wind speed, insolation amount, and room temperature, the brightness of the indoor illuminance and the surface of the room is measured or calculated, and in the step of calculating the required heating and cooling energy and the required ventilation amount according to the operation mode. After calculating the required indoor illuminance of the building, natural light can be introduced into the room by calculating the shading degree of the shading part, that is, the inclination angle of the louver.

In order to enable the user to control the double skin system in real time, the controller must be accessible regardless of the user's location. Therefore, it is preferable that the control unit according to the present invention be configured to be accessible through a network such as the Internet, an intranet, or a wireless Internet.

If the control unit is accessible via wired or wireless Internet, it is possible to monitor the value input from the double jacket system and the operating status of the louver or ventilation damper even when the user is outdoors, and if necessary, change the operation mode or directly The double skin system can be controlled in a desired manner, allowing control in real time. As described above, it is possible to set an appropriate authority scheme for each user in the process of accessing through a network so that control conflicts between users do not occur.

Since the configuration of connecting the control unit to be accessible through a network such as the Internet is obvious to those skilled in the art, a detailed description thereof will be omitted.

On the other hand, the control unit is connected to the display unit so that the user can provide a user interface for monitoring. When the control unit is implemented in a computer system, the display unit may be implemented in the form of a monitor. When the user accesses the wired or wireless Internet to the control unit, the display unit of the terminal used by the user functions as the display unit of the control unit according to the present invention. .

When the display unit is connected to the control unit, after the control unit calculates the inclination angle of the louver and the opening / closing degree of the ventilation damper, input values such as various measured values and calculated values used for the calculation by the control unit and values calculated by the control unit are displayed on the display unit ( 122) allow the user to monitor the current status. As a result, the user can check the situation of the double jacket system in real time and control the desired operation mode.

The controller determines the optimum tilt angle of the louver and the optimum opening and closing of the ventilation damper to minimize the cost function for a certain time interval. The cost function is a utility function of energy, air comfort, heat comfort, and ventilation performance. In the energy mode, the energy consumption of a building through a double skin is therefore a cost function as the heating and cooling load of a building increases due to the double skin. The value of is also increased, and the comfort, heat comfort, and ventilation performance are similar. For example, in the thermal comfort mode, the cost function increases as the PPD of the occupant increases.

The control object can be operated immediately after the inclination angle of the louver and the opening / closing degree of the ventilation damper are calculated by the control unit. It is also preferable to operate the louver and the ventilation damper after fine tuning the inclination angle and the opening and closing degree of the ventilation damper and repeating the previous step until the value converges within a predetermined range of error. By adjusting the calculated values through simulation and iteration before operating the control object as described above, control can be more stably controlled in the double skin system.

The controller compares the current control variable value with the optimum control variable value adjusted by the simulation, and when the current control variable value is different from the optimal control variable value, the current control state corresponds to the optimum control variable value. Readjust the operation of the control object of the double skin system so that.

That is, the control unit obtains the most optimal control variable value in terms of system performance such as energy, visual comfort, thermal comfort, ventilation and noise through iterative calculation.

Finally, to operate the louver installed in the double skin system to achieve the inclination angle calculated by the control unit, and to operate the first ventilation damper and the second ventilation damper to the calculated opening and closing degree (130).

In order to operate a control object such as a louver, a first ventilation damper, and a second ventilation damper through a signal transmitted from the control unit, a driving unit including a driving motor must be coupled to each control object. The driving unit includes a part for receiving a signal transmitted from the controller and generating a signal for driving the driving motor to correspond to the signal.

The detailed configuration of the drive motor coupled to the louver or the ventilation damper is obvious to those skilled in the art, so a detailed description thereof will be omitted.

That is, the control unit according to the present invention transmits a driving signal to the driving unit to operate the control object, and as described above, when the control unit is connected to the double envelope system through a network such as the Internet, the driving signal is also transmitted from the control unit to the driving unit. It is configured to be transmitted through a network such as the Internet.

Normally, the drive unit including the drive motor may be connected to the network through a LAN, and the control unit may be connected to the same network, and then the control unit and the drive unit may be connected to the network by setting a protocol for bilateral communication. However, the present invention is not limited to the network connection method between the controller and the driver as described above, and other types of connection methods may be used within a range apparent to those skilled in the art.

2 is a conceptual diagram showing the configuration of a double envelope system according to an embodiment of the present invention. 2, the sensor unit 1, the first shell 10, the first ventilation damper 12, the first ventilation damper driving unit 14, the second shell 20, and the second ventilation damper 22. The second ventilation damper driver 24, the hollow layer 30, the louver 32, the louver driver 34, the control unit 40, and the terminal 42 are shown.

The double envelope system of the present invention is to generate the optimal indoor environmental conditions in real time according to the environmental variables of the indoor and outdoor and the user's preference, the first shell 10, the first shell 10 is installed on the outdoor side of the building It relates to a double skin system composed of a second sheath 20 is installed on the outdoor side of the first sheath 10 while being spaced apart from the hollow layer (30).

First and second ventilation dampers 22 are installed at upper and lower portions of the first outer shell 10, and second and second ventilation dampers 22 are disposed at upper and lower portions of the second outer shell 20. The louver 32 is installed in the hollow layer 30 between the two shells 20. The double skin system controls the degree of opening and closing of the ventilation dampers installed in each skin and the inclination angle of the louver 32 installed in the hollow layer 30 to determine whether the insolation amount is inflow and the airflow buffered in the hollow layer 30. The indoor environment of the building is controlled by controlling whether it is indoor or outdoor.

Double envelope system according to the present invention includes a control unit 40 for forming an optimal indoor environment, the control unit 40 is set to a predetermined operating mode according to the environmental variables of the building and the user's preferences ventilation damper and louver Control the operation of 32.

Meanwhile, the controller 40 may be directly connected to the driving units 14, 24, and 34 of the double skin system, but more preferably, the controller 40 may be connected to a network such as a wired, wireless Internet, or an intranet. As a result, the present invention can be controlled in real time from a remote place as well as when the user is in the room.

In order to control the double skin according to the indoor and outdoor environmental variables of the building, a sensor is installed in the building or the first and second skin 20, and the measurement signal generated from the sensor is transmitted to the controller 40. The sensor is installed at an appropriate position corresponding to the measured value, and in FIG. 2, the sensor unit 1 is illustrated as an integrated concept for convenience of description. Accordingly, various sensors included in the sensor unit 1 of FIG. 2 are installed at appropriate positions in correspondence with values to be measured. Since the installation position for each sensor is obvious to those skilled in the art, a detailed description thereof will be omitted.

Since the present invention is for controlling the double envelope system in real time even in a remote place, the input value measured from the sensor is transmitted to the controller 40 through a network such as the Internet. To this end, the sensor unit 1 further includes components, circuits, and the like for network connection and signal transmission within a range apparent to those skilled in the art.

In order to control the double skin system according to the user's preference, the control unit 40 includes visual comfort mode, thermal comfort mode, automatic driving mode, energy saving mode, occupant selection mode, night mode, etc. based on the user's preference of the building. The setting values for the operation mode are stored in advance.

The user assigns weights according to his or her preference for the various factors in which the double skin system affects the indoor environment. These indoor environmental factors include indoor temperature, indoor illuminance, distribution of indoor illuminance, whether to secure view, indoor CO ₂ concentration, outdoor pollution, outdoor noise level, energy consumption, and the like. The input of the user can determine the highest and lowest allowable limits of each element, and can also determine the relative importance between each element by changing the weight for each element.

In addition, the control unit 40 calculates the required heating and cooling energy of the building and the required ventilation amount, etc. in response to the predetermined operation mode set by the user, and based on these values, the inclination angle of the louver 32 and the first ventilation damper 12. And the degree of opening and closing of the second ventilation damper 22 is calculated.

On the other hand, if you want to introduce natural light using the double skin system as described above, the required room illuminance is calculated by the control unit, this value is reflected in calculating the inclination angle of the louver (32). In addition, the double envelope system according to the present invention may not only introduce natural light, but also may be interlocked with an indoor lighting system such as on-off, dimming, and the like of a fluorescent lamp.

In the control unit 40, a 'cost function' is set in advance, and the 'cost function' is treated as an increase in cost as the energy consumption increases out of the comfort range for each indoor environment element. The control unit 40 substitutes the input value of the sensor unit 1, the simulation result performed by the control unit 40, and the user's weight into the 'cost function' based on the input value of the sensor unit 1, thereby minimizing the calculated value. To derive

On the other hand, in general, the HVAC system is installed in the building to provide heating and cooling. In this case, since the indoor environment is not controlled only by the double skin system, the controller 40 controls the amount of cooling / heating energy or ventilation supplied by the HVAC system. Take into account the required heating and cooling energy or ventilation required to be provided by the double skin system.

As described above, when the controller 40 of the present invention is connected through a network to control the double skin system in real time, the controller 40 and a display unit accessible through the network are additionally provided. Accordingly, the value calculated by the control unit 40 is displayed on the display unit in real time so that the user can monitor this and control the double skin system in a desired direction. However, when the control unit 40 according to the present invention includes functions of user monitoring and an operation panel, the display unit may be directly connected to the control unit 40 by a cable or the like.

When both the sensor unit 1 and the driving units 14, 24, 34 of the double envelope system are connected to the control unit 40 via a network, the user accesses the control unit 40 using the terminal 42 capable of network connection. This allows control of the double skin system.

As shown in FIG. 2, when the control unit 40 of the present invention is connected to the sensor unit 1, the driving units 14, 24, 34, and the display unit in such a way that all can communicate through the Internet, By connecting to the Internet using the terminal 42, the current state of the double skin system can be monitored and the double skin system can be operated in the desired direction by sending appropriate input values. Of course, only a user with proper control can access the control unit of the double skin system.

The display unit receives the value measured by the sensor unit 1, data input by the user, and current control variable data from the controller 40 and displays the received value.
