The cloud server 110 receives environmental data including the building data and the outdoor temperature of the control target buildings 10 registered in the data base (DB) 115 via the communication network 50, It is possible to calculate the total load of the building, which is a power amount, and provide it to the main controller 130 installed in the registered control target building 10.

The cloud server 110 receives input of building data information required to calculate the cooling / heating load of the building to perform power control management through the user terminal 120 connected through the communication network 50, And can input and register building information including an address.

The heating and cooling load of the building is calculated using the ASHRAE GRP-158 proposed by the American Refrigeration and Air Conditioning Society.

The information input to calculate the heating and cooling load of the building includes office size, wall area, wall material, ceiling area, ceiling material, door area, door material, window area, window material,

The cloud server 110 is constructed to receive environmental information including outdoor temperature, humidity, and radiation amount information by region from the weather control server 190 through the communication network 50.

That is, the cloud server 110 receives environmental information including the outdoor temperature of the area to which the control target building 10 registered from the weather control server 190 belongs.

The user terminal 120 is connected to the cloud server 110 through the communication network 50 to set the target demand power for the registered control target building.

The user terminal 120 is provided with a web module for supporting access to the cloud server 110 and for browsing information supported by the cloud server 110 and for setting target demand power for the registered control target building.

The user terminal 120 may be a smart phone.

Here, the target demand electric power is a value that allows the user to limit the upper limit value of the demand electric power used in the control target building 10. [

The use power transmission unit 140 detects the power consumption of the building to be controlled for a predetermined unit time, for example, for 15 minutes from the meter 20 and transmits the average power consumption to the main controller 130.

The main controller 130 is constructed so as to be able to communicate with the cloud server 110 and the actual terminology 150.

When the average power consumption of the control target building received from the use power transmission unit 140 is greater than the target demand power received from the cloud server 110 through the communication network 50, the main controller 130 controls the actual power adjustment amount And transmits the calculated actual power adjustment amount to the corresponding actual termizer 150.

Further, the main controller 130 calculates a PMV (Predicted Mean Vote) for each of the chambers of the controlled building 10 in units of a set cycle, and records the calculated latest values to be updated.

Herein, the PMV is an index for evaluating the thermal comfort in consideration of the influence of the air temperature, the air flow, the humidity, the average radiation temperature, the activity amount, and the personal wear amount. The indoor humidity, and the air-blowing speed information received from the air conditioner 150.

The activity amount and the personal wear amount information when calculating the warm and pleasant feeling can be applied in advance, and the calculation method is variously disclosed in Korean Patent Laid-Open No. 10-2010-0131819, and the detailed description will be omitted.

The actual power adjustment process of the main controller 130 will be described later.

The actual air conditioner 150 is provided for each room of the control target building 10 and controls the control target air conditioner 160 according to the actual power adjustment amount received from the main controller 130.

Here, the air conditioner 160 has a sensor unit 162 for detecting room temperature and humidity, and a cooling / heating unit 164 for supporting cooling, heating, and dehumidifying operations.

In this case, the actual air conditioner 150 can receive the room temperature and humidity measured by the sensor unit 162 of the air conditioner 160 and the blowing speed applied during the operation while communicating with the air conditioner 160 .

Alternatively, the actual sensor 150 may be provided with a sensor for measuring temperature and humidity.

2, the actual transmitter 150 includes a real communication unit 151 for performing radio communication with the main controller 130, an infrared transmission / reception unit 155 for controlling the operation of the air conditioner 160, The operation of the air conditioner 160 is controlled in accordance with the indoor temperature sensor 171 for measuring the indoor temperature, the indoor humidity sensor 172 for measuring the indoor humidity and the control information received via the room communication unit 151, And an actual fisher 153 that provides the indoor temperature and the indoor humidity to the main controller 130. [

The actual controller 150 converts the actual power adjustment amount received from the main controller 130 into temperature, updates the indoor set temperature, and controls the air conditioner 160 to maintain the room at the updated set temperature.

The actual controller 150 is provided with a look-up table in which appropriate humidity information corresponding to the set temperature is recorded. The controller 150 controls the humidity of the humidity recorded in the lookup table to correspond to the set temperature updated in accordance with the control information received from the main controller 130 So that the air conditioner 160 is maintained.

Meanwhile, the air conditioner 160, which is responsible for the heating of each room, operates according to the operating condition set by the occupant, and when a control signal is received from the actual air conditioner 150 through the infrared transmitting / receiving unit 155, Operation is controlled.

Hereinafter, the use power control process of the control target building in the indoor comfort control system 100 will be described with reference to FIG.

First, when receiving the target demand power set by the user from the cloud server 110, the main controller 130 determines whether or not the actual demand power detected by the meter 20 and received through the power- The average power usage for the unit time set for the power is compared (step 210). Here, the target demand power and the average power consumption are converted into a value converted to be equal to the power used for the same unit time.

If it is determined in step 210 that the average power usage is greater than the target demand power, the total power adjustment amount is calculated (step 212).

Here, the total power adjustment amount is determined by the main controller 130 as the total power adjustment amount by receiving the total building load from the cloud server 110 and subtracting the target demand power from the received total building load.

The determined total power adjustment amount is the amount of power that must be subtracted or reduced overall in the current power use state.

Next, the average comfort feeling (average PMV), which is the average of the room warm comfort feeling (PMV), is calculated by dividing the previously calculated warm comfort feeling (PMV) for each room controlled by the actual speaker 150 by the total number of rooms (Step 214).

Then, when each room is adjusted by the calculated average PMV, the actual required power required to satisfy the average comfort is calculated (step 216).

Here, the room temperature, the room humidity, or the operating power corresponding to the PMV value corresponding to the PMV value for each room are calculated and recorded from the building data in advance.

Therefore, the main controller 130 may calculate the required power to be further subtracted or added when the PMVV is adjusted from the current PMVV to the average PMV from the room temperature or the operating power information corresponding to the recorded PMV.

Next, the magnitude of the total sum of the actual required power calculated in step 216 and the total adjusted power amount calculated in step 212 are compared with each other (step 220).

Here, the total sum of the actual required power is the sum of the power amounts to be subtracted, and the magnitude, that is, the absolute value is compared in step 220.

If the total adjusted power amount is less than or equal to the sum of the actual required power in step 220, the actual required power is determined as the final actually adjusted power amount (step 222).

If it is determined in step 220 that the total adjusted power amount is larger than the sum of the actual required power, it means that additional power subtraction is performed. To this end, a subtraction adjustment method (Step 232), which is calculated in step 216 according to the actual required power.

As an example, as a subtraction method applied in step 232, a divided divided value obtained by dividing the difference value corresponding to the difference in the sum of the total adjusted power amount and the actual required power calculated in step 216 by the total number of rooms, A method of reflecting on actual required power may be applied.

The actual required power adjusted through step 232 is determined as the final real adjusted power (step 234).

Meanwhile, the final real adjusted power determined through step 222 or 234 is transmitted to the corresponding actual termizer 150 (step 240).

Thereafter, each of the physical devices 150 updates the set temperature corresponding to the final real adjusted power received through step 240 (step 250).

In this case, the actual power required for raising the unit temperature (for example, 1 占 폚) is recorded in each of the actual sound generators 150, and the set temperature is updated in accordance with the actually adjusted electric power using the conversion relation between the electric power and the temperature .

Thereafter, the actual air conditioner 150 controls the operation of the air conditioner 160 so that the indoor is maintained at the updated set temperature (step 260).

On the other hand, as to the humidity of the room, the air conditioner 160 is controlled so that the humidity corresponding to the updated set temperature is maintained as described above.

According to such an indoor comfort control system, the satisfaction of comfort of the occupant can be increased by adjusting the power demand of each room so that the demand power of the entire building is within the target demand power set while the deviation of the warm comfort of each room is minimized .
