Description

[0001] The present invention relates to an integrated control method for indoor environment devices,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for integrally controlling indoor environmental devices of various models installed in a room.

 Generally, the humidity increases when the air conditioner such as an air conditioner is operated for cooling, and when the heating device such as a boiler is operated for heating, the humidity is lowered.

Also, when the humidifier is operated, the temperature is somewhat lowered, and the temperature rises slightly when the humidifier is operated.

However, if cooling and humidification are required at the same time, only the air conditioner may be operated, but many users operate the humidifier together. Likewise, when both heating and dehumidification are needed simultaneously, many users run both the heating and dehumidifier together.

Here, waste of energy may occur, excessive cooling, or excessive heating may occur.

In addition, a user who feels bad indoor air quality may operate the ventilator or open the window for ventilation. In this case, the room temperature needs to be changed and another energy is required for cooling or heating the room again.

In this way, when the indoor environment devices are individually controlled, not only hassle but also energy waste is generated.

To solve this problem, an integrated control method using enthalpy has been proposed. However, these methods are merely to control quickly (that is, to shorten the running time as much as possible) by using only temperature and humidity, The characteristics of the students and the presence or absence of students.

Hereinafter, the present invention will be described in more detail with reference to the drawings.

1. Description of the system

1, the system for performing the method according to the present invention includes a control unit 100, an input / output unit 200, a room prediction module 300, an outdoor temperature / humidity sensor, an outdoor air quality sensor, An outdoor temperature and humidity sensor, a room sensor, and multi-type indoor environmental devices 410 to 480.

The control unit 100 collects information from various sensors, receives an operating mode input by the user in the input / output unit 200, controls the operation of the indoor environment devices 410 to 480, and controls the input / output unit 200 And outputs the information.

It is noted that the control unit 100 is the subject of each step of the integrated control method described below.

The input / output unit 200 inputs the operation mode desired by the user and outputs the outdoor temperature and humidity, the outdoor air quality, the indoor temperature and humidity, and the indoor air quality sensed by the outdoor temperature and humidity sensor, the outdoor air quality sensor, the indoor temperature and humidity sensor, and the outdoor temperature and humidity sensor.

For example, the input / output unit 200 may include a door camera screen display unit, a door lock device control unit, and the like, and may be a wall pad provided for each household.

The losing room prediction module 300 has a function of confirming whether or not the current occupant is confirmed by the occupant detection sensor and a function of confirming whether the occupant is out of the day and time (that is, the outgoing time) And the like.

Specifically, the staff room prediction module 310 checks the power consumption of the indoor environment equipments 410 to 480 for each weekday and time for one week, and based on the power consumption of the indoor environment equipments 410 to 480, And predicts the day of the week and the time at which the amount of increase in the amount of power usage becomes larger than the preset reference as the return time.

The indoor environment devices 410 to 480 include a ventilation device 410, a window opening / closing device 420, a humidifier 450, a dehumidifier 460, a heating device 470 and a cooling device 480.

The features of each device are shown in Fig.

The ventilator 410 is a forced ventilation device using energy, and has a function of controlling the indoor air quality although the function of temperature and humidity control is low.

The window opening / closing device 420 is a device for opening or closing a window. There is practically no energy use. If the window is opened by the window opening / closing device 420 according to the outside air condition, the temperature and humidity can be adjusted and the indoor air quality can be changed.

Hereinafter, the ventilator is referred to as including both the ventilator 410 and the window opening / closing device 420.

The canopy opening and closing apparatus 430 is a device for opening and closing a canopy such as a blind. There is practically no energy use. The temperature may rise when the sunshade is opened during the daytime.

The air cleaner 440 uses energy and has an indoor air quality control function.

The humidifier 450 uses energy and raises the humidity. The humidifier 450 has a temperature control function to lower the temperature when the humidifier 450 is operated and the humidity rises.

The dehumidifier 460 uses energy and lowers the humidity. When the dehumidifier 460 is operated to lower the humidity, the temperature rises to some extent and thus has a temperature control function.

The heating device 470 uses energy considerably and raises the temperature. When the heating device 470 is operated and the temperature rises, the humidity is lowered, so that it has a part of the humidity control function.

The heating device 470 can be divided into an air conditioning heating device and a floor heating device. In each case, the comfort mode can be changed (see FIG. 3).

Cooling unit 480 uses energy considerably and lowers the temperature. When the cooling device 480 is operated to lower the temperature, the humidity increases, and thus, it has a part of the humidity control function.

An example of the air conditioner 480 is an air conditioner.

All of the indoor environment devices 410 to 480 are integrally controlled by the control unit 100, so that the current indoor environment can be included in the comfortable range more quickly or can be included in the comfortable range using only less energy.

Here, the comfortable range is a predetermined temperature and humidity range.

As shown in FIG. 3, the comfort range on the cooling side is 24.4 to 26.5 degrees Celsius and 40 to 55% humidity, and the comfortable range on the heating side is 22.1 to 25.5 degrees Celsius when heating the air conditioner and 21.4 degrees Celsius To 23.9 degrees C and a humidity of 40 to 55%.

The energy saving comfort range in the energy saving mode is preferably wider than the general comfort range for energy saving.

As shown in FIG. 3, the comfort range on the cooling side is 24.0 to 26.8 degrees Celsius and 38 to 57% humidity, and the comfortable range on the heating side is 21.7 to 25.8 degrees Celsius when heating the air conditioner and 21.0 degrees Celsius To 24.3 degrees and a humidity of 38 to 57%.

2. Explanation of the integrated control method

First, the operation mode is selected. The selected operating modes are cooling comfort mode, heating comfort mode, cooling energy saving mode, heating energy saving mode, integrated comfort mode, integrated energy saving mode, ventilation mode, sleep mode, and outgoing / return mode. User mode, and the like.

The above modes of operation are commonly followed by the following steps.

First, the operation mode is selected through the input / output unit 200.

Next, the outdoor air quality, the indoor air quality, the outdoor temperature and humidity and the indoor temperature and humidity are sensed through the respective sensors, and the outdoor enthalpy and the indoor enthalpy are calculated using the sensed outdoor temperature and humidity. The enthalpy calculation method is well known, and a detailed description thereof will be omitted.

In particular, the temperature and humidity and the air quality are continuously sensed in real time using respective sensors, and may be outputted through the input / output unit 200 such as a wall pad.

Next, when the outdoor air quality is better than the indoor air quality, the operation mode is about cooling, the outdoor enthalpy is smaller than the indoor enthalpy, the operation mode is about heating, and the outdoor enthalpy is larger than the indoor enthalpy, Ventilation is done first.

The reason why the ventilation is performed first is to save energy by reducing the operating time of the humidifier 450, the dehumidifier 460, the heater 470, and the air conditioner 480 as well as the air quality.

After the ventilation is performed, at least one of the humidifier 450, the dehumidifier 460, the heating device 470 and the cooling device 480 is operated to perform heating or cooling so that the indoor temperature and humidity are within the comfortable range.

Hereinafter, the integrated control method according to the present invention will be described in detail for each operation mode with reference to FIG. 4 through FIG.

2.1 Cooling Comfort Mode

The cooling and comfort mode will be described with reference to Figs. 4 and 8. Fig.

If the outdoor air quality is better than the indoor air quality and the outdoor enthalpy is smaller than the indoor enthalpy (S410), the ventilator operates for a predetermined period of time to perform ventilation (S420).

If the outdoor air quality is not better than the indoor air quality, it is preferable that the ventilation is not performed.

If the outdoor enthalpy is larger than the indoor enthalpy, the energy consumed by the humidifier 450 and the air conditioner 480, which are operated later due to the ventilation, is increased, so that it is preferable that the ventilation is not performed.

The operation of the ventilation device can be stopped when the outdoor air quality becomes worse than the indoor air quality, when the outdoor enthalpy becomes larger than the indoor enthalpy, or when the predetermined predetermined time elapses. The preset predetermined time can be freely set, for example, 10 minutes, 30 minutes, 1 hour, or the like. It may be set shorter than the case where rapid cooling is desired and may be set or changed by the user before or during operation through the input / output unit 200. [

Since the indoor temperature and humidity are sensed in real time, the indoor temperature and humidity after the ventilation is confirmed, and the current point on the humidity chart is confirmed (S430).

At least one of the humidifier 450 and the air conditioner 480 operates according to the current point to be confirmed (S440). Accordingly, the current point moves toward the comfortable range on the humidifier line.

Since the indoor air quality is also sensed in real time, when the indoor air quality is lower than the preset reference value during operation of at least one of the humidifier 450 and the air conditioner 480, the air cleaner 440 is operated instead of the ventilator ). If the ventilation device is operated to increase the air quality, the energy consumption of the humidifier 450 and the cooling device 480, which are operated as much as they are, is increased.

Thereafter, if it is confirmed that the current point is within the comfortable range, at least one of the humidifier 450 and the air conditioner 480, which was operated, is stopped (S460).

Referring to FIG. 8 together, step S440 will be described in more detail.

Depending on the location of the current point according to the indoor temperature and humidity, the indoor environment equipment to be operated varies.

In general, when cooling is required, the present point will be mainly described in the case where the current point is included in any one of the three areas of C1, C2, and C3.

Only the cooling device 480 operates when the current point is located in the area C1 between the lines in which the humidity upper limit and the lower limit line of the comfortable range on the moisturizer line extend to the high temperature side.

Only the humidifier 450 is operated when the current point is located in the area C3 between the lines extending from the comfortable range of the temperature and the left and right lines on the humidifying line to the low humidity side.

The humidifier 450 and the cooling apparatus 480 both operate when the current point is located in the area C2 between the line in which the humidity lower limit of the comfortable range extends to the high temperature side and the line in which the temperature right line extends to the low humidity side on the humidifier line do.

Here, it is preferable that a line extending to the high-temperature side of the humidity upper limit line and the lower limit line of the comfortable range on the above-described humidifier line is located below the relative humidity curve. This is because even if only the cooling device 480 is operated, humidification is performed, and even if only the humidifier 450 is operated, the cooling is somewhat performed. Thus, further energy saving is possible.

In some cases, if the humidity is high, there may be a current point in the area C5 between lines where the left and right temperature lines of the temperature range on the humidifier line extend to the high humidity side. In this case, the dehumidifier 460 must be operated, and the temperature may rise in this process. Thus, the cooling device 480 may be further driven if necessary.

As another example, the current point may be located in a region C4 between the line in which the humidity upper limit of the comfortable range extends to the high temperature side and the line in which the temperature right line extends to the high humidity side on the moisturizer line. In this case, the dehumidifier 460 and the cooling apparatus 480 are operated together.

In this way, it is possible to reduce the amount of energy consumed after the ventilation is first performed and to cool the air, and to improve the air quality with the minimum energy.

The point at which the room temperature is lowered during operation of the humidifier 450 is used, which is more effective because it can reduce the use of the energy-consuming cooling apparatus 480.

Even when the air quality is lowered during cooling, the ventilation equipment is not operated, so the air quality can be improved while reducing unnecessary energy consumption.

When the indoor temperature and humidity reaches the proper comfort range, the operation of all the indoor environment devices is automatically stopped and convenient energy saving is possible.

2.2 Heating and cooling mode

The cooling and comfort mode will be described with reference to Figs. 5 and 9. Fig. The heating comfort mode is understandable as opposed to the cooling comfort mode. If the outdoor air quality is better than the indoor air quality and the outdoor enthalpy is larger than the indoor enthalpy (S510), the ventilator operates for a predetermined period of time (S520).

The operation of the ventilation device can be stopped when the outdoor air quality becomes worse than the indoor air quality, when the outdoor enthalpy becomes smaller than the indoor enthalpy, or when the predetermined predetermined time elapses.

After the ventilation is performed, the current point is confirmed on the humidifier line according to the indoor temperature and humidity (S530), and at least one of the dehumidifier 460 and the heating device 470 operates according to the current point (S540).

If the indoor air quality is lower than the predetermined reference value during operation, the air cleaner 440 is operated (S550).

If it is confirmed that the current point is within the comfortable range, the operation of any one of the dehumidifier 460 and the heating device 470 that was operated is stopped (S560).

Step S540 will be described in detail with reference to FIG. It can be understood that it is the opposite of the description of step S440.

Only the heating device 470 operates when the current point is located in the area H1 between the lines in which the upper and lower humidity limits of the comfortable range are extended to the low temperature side on the moisturizing line.

Only the dehumidifier 460 operates when the current point is located in the area H3 between the lines extending to the high humidity side in the comfortable range of temperature on the humidifier line.

The dehumidifier 460 and the heating device 470 both operate when the current point is located in the area H2 between the line in which the humidity upper limit of the comfortable range extends to the low temperature side and the line in which the temperature left line extends to the high humidity side do.

Here, it is preferable that a line extending to the low temperature side of the upper limit and the lower limit of humidity in the comfortable range on the above-described humidifier line is located above the relative humidity curve. This is because, even if only the heating device 470 is operated, dehumidification is performed and only the dehumidifier 460 is operated, the heating is somewhat performed.

If there is a current point in the area H5 between the lines extending to the low humidity side of the comfortable range of temperature on the humidifier line, the humidifier 450 must be operated, and the temperature may drop in this process. Therefore, the heating device 470 may be further driven if necessary.

The current point may be located in a region H4 between the line in which the lower limit of the humidity range of the pleasant range extends to the lower temperature side and the line in which the temperature left line extends to the lower humidity side on the moisturizer line. In this case, the humidifier 450 and the heating device 470 are operated together.

2.3 Cooling Energy Saving Mode

The cooling energy saving mode will be described with reference to Fig. If the cooling air conditioning mode is for rapid cooling, the cooling energy saving mode is an operation method for entering the comfortable range while saving the energy as much as possible.

First, an energy saving comfort range wider than the comfortable range is set (S601). See FIG.

If the outdoor air quality is better than the indoor air quality and the outdoor enthalpy is smaller than the indoor enthalpy (S610), the window is opened for a predetermined period of time set by the window opening / closing device 420 rather than the ventilator 410 (S620). Thereby preventing the energy consumption by the operation of the ventilator 410.

The case where the window closing device 420 closes the window is as described in the cooling and cooling mode.

The current point is confirmed on the humidifier diagram according to the indoor temperature and humidity after the window is closed by the window opening and closing apparatus 420 (S630), and at least one of the humidifier 450 and the cooling apparatus 480 is operated (S640).

The specific operation method of step S640 is as described in step S440.

During operation, when the indoor air quality is lower than a predetermined reference value, the air purifier 440 is operated. However, under the condition that the outdoor air quality is better than the indoor air quality and the outdoor enthalpy is smaller than the indoor enthalpy (that is, the condition is that there is no energy loss due to opening of the window), the window opening / closing device 420 reopens the window and operates the air purifier 440 Thereby reducing the energy consumption by the < / RTI >

If it is confirmed that the current point is within the energy saving comfort range, the operation of any one of the humidifier 450 and the air conditioner 480, which was operated, is stopped (S660).

In the cooling energy saving mode, the air purifier 440, the humidifier 450, and the air conditioner 480 are driven as much as possible through the inflow of outside air by ventilation as compared with the cooling / comfort mode.

2.4 Heating energy saving mode

The heating energy saving mode will be described with reference to Fig. If the heating comfort mode is for rapid heating, the heating energy saving mode is the operating method to enter the comfortable range while saving the energy as much as possible. Also, it can be understood as the opposite of the cooling energy saving mode.

Similarly, an energy saving comfort range wider than the comfortable range is set (S701). See FIG. The comfort range may vary depending on the type of the heating device 470.

If the outdoor air quality is better than the indoor air quality and the outdoor enthalpy is larger than the indoor enthalpy (S710), the window is opened for a predetermined time set by the window opening / closing device 420 rather than the ventilator 410 (S720).

The case where the window opening / closing apparatus 420 closes the window is as described in the heating comfortable mode.

The current point is confirmed on the humidifier diagram according to the indoor temperature and humidity after the window is closed by the window opening / closing device 420 (S730), and at least one of the dehumidifier 460 and the heating device 470 is operated (S740).

The detailed operation method of step S740 is as described in step S540.

During operation, when the indoor air quality is lower than a predetermined reference value, the air purifier 440 is operated. However, under the condition that the outdoor air quality is better than the indoor air quality and the outdoor enthalpy is larger than the indoor enthalpy (that is, the energy is not lost due to the opening of the window), the window opening / closing device 420 opens the window again to operate the air purifier 440 Thereby reducing the energy consumption by the < / RTI >

If it is confirmed that the current point is within the energy saving comfortable range, the operation of any one of the dehumidifier 460 and the heating apparatus 470 that was operated is stopped (S760).

2.5 Integrated comfort mode

The integrated comfort mode is a mode in which cooling or heating is performed according to the current indoor temperature / humidity level even if the user does not set cooling or heating. It can be used mainly in spring or autumn.

When the integrated comfort mode is selected, it operates in the cooling comfort mode when the room temperature is higher than the comfortable range, and operates in the heating comfort mode when the room temperature is lower than the comfortable range.

2.6 Integrated energy saving mode

The integrated energy saving mode is also a mode in which cooling or heating is performed according to the current indoor temperature / humidity level even if the user does not set cooling or heating. It can be used mainly in spring or autumn.

We use wide range of energy conservation comfort range.

When the room temperature is higher than the energy saving comfort range, it operates in the cooling energy saving mode and when the room temperature is lower than the energy saving comfort range, it operates in the heating energy saving mode.

2.7 Ventilation mode

The ventilation mode is a method in which ventilation is performed to raise the air quality without cooling or heating.

When the outdoor air quality is better than the indoor air quality and the outdoor temperature is within the predetermined comfortable range, the ventilation device 410 operates. If the outdoor air quality is worse than the indoor air quality or the outdoor temperature is outside the preset comfortable range, Opens the window.

This enables ventilation while minimizing energy consumption.

2.8 Sleep mode

The sleep mode is a method of controlling the temperature by automatically cooling or heating the user during sleep.

For example, it is automatically operated as a cooling energy saving mode or a heating energy saving mode for energy saving for a preset time such as 3 to 5 am.

Of course, the preset time can be freely adjusted according to the life pattern of the user.

2.9 Outgoing / returning mode

The outgoing / return mode can be done in two ways.

The first method is a method in which the indoor environment device operates only when the staff room prediction module 300 detects the room occupancy by the occupancy detection sensor, and automatically stops when the occupant confirms that there is no occupant. Unnecessary energy consumption can be prevented.

The second method is a method in which the outgoing time and return time predicted by the occupancy prediction module 310 are utilized.

It is possible to further prevent energy consumption by closing the window by operating the window opening / closing device 420 at the predicted outgoing time and terminating the other indoor environment devices in operation.

In addition, the indoor environment device can be operated in accordance with the estimated return time. Here, it is preferable to operate a predetermined time earlier than the predicted return time.

The mode in which the indoor environment device is operated may be any one selected from the cooling comfort mode, the heating comfort mode, the cooling energy saving mode, the heating energy saving mode, the integrated comfort mode, and the integrated energy saving mode.

2.10 Custom Mode

The user can designate the desired temperature and humidity as the user comfortable range, thereby enabling the indoor environment appliance to operate.

For example, when a user needs a low temperature / low humidity environment rather than a general comfort range for a reason such as playing a musical instrument indoors or performing an art work, the user can use the input / output unit 100 to set a comfortable range The comfort mode, the energy saving mode, and the like can be performed.

The manner in which it is performed is the same as described above.
