Air Conditioning refers to keeping the air temperature, humidity, air flow, and cleanness in a state suitable for indoor use. In modern society, it is common to live in a confined space within a limited space of various buildings such as office buildings, apartment buildings, and condominiums in urban areas. In order to improve, it is required to keep the temperature and humidity and cleanness of indoor air in an appropriate state at all times.

The air conditioning method of the building is based on installing an air conditioner in the machine room and supplying the air harmonized by the air conditioner to each room through the duct.It can be divided into the central method and the individual method based on the air distribution method. Among them, the central method produces heat medium from the heat source equipment installed in the central machine room and supplies it to the air conditioner installed on the secondary side, thereby supplying the harmonized air to each room or zone. The central air conditioning system can be classified into an all air system, an air-water system, and an all water system according to the type of heat medium used.

Conventionally, the central air conditioning system of a building may be divided into a constant air flow method and a variable air flow method according to which of the temperature or air flow amount of the air supplied to each room is changed to match the load variation of the room. Among these, the constant air flow method is a method of coping with load fluctuations by changing the air blowing temperature while maintaining a constant air flow rate, and the Variable Air Volume System (VAV: Variable Air Volume System) keeps the air blow temperature constant and changes according to load fluctuations.

For example, if the output is 10V when the slide switch is ON and the output is 0V, the damper is fully open at 10V output, and the damper is all at 0V output. If the output is between 0-10V, the damper can be opened in proportion to it.

Referring to FIG. 2, the sensor unit 541 detects the air volume of the air supply guide duct 35, and a converter 542 converts the physical quantity measured by the sensor unit 541 into an electrical signal and outputs the electrical signal. When the hot air flow rate sensor 540 is exposed to the flow of gas in a state in which the heating wire 541a of the sensor unit 541 is heated, the hot air flow rate sensor 540 measures the air flow rate by the degree of cooling of the heating wire 541a by the gas or the amount of heat absorption of the gas. That's the way it is.

4 is a flowchart illustrating a control method sequence of an intelligent building control system for optimal management and energy saving of an office building facility according to an embodiment of the present invention.

As shown in the drawings, the method of the present invention provides a method for achieving the above object, the monitoring unit measuring the temperature and humidity of the building exterior and interior at regular intervals (S1); Calculating an average value of temperature and humidity values measured at the predetermined time intervals (S2); Transmitting and storing the calculated average value to a database (S3); Deleting the data before the point in time after obtaining the average value (S4); Receiving, by the air conditioning control command server, temperature, humidity, and air volume control information input from a user's PC connected to the Internet connection unit (S5); Calculating a sum of the selected user's selection values (S6); Repeating from step S2 to step S6 after the time point at which the sum of the average value and the selection value is obtained (S7); Learning to find a temperature and humidity suitable for each situation by using the average value of the temperature and humidity and the sum data of the user's selection value (S8); Controlling, by the air conditioning control device, an air conditioning system using the learning data (S9); Characterized in that consists of.

The step S1 of the monitoring unit measuring the temperature and humidity of the exterior and the interior of the building at regular time intervals is a step of measuring the current temperature and humidity in order to warm the temperature to control the temperature and humidity of the air conditioning system. The reason for measuring the temperature and humidity of the outside of the building is that the comfort of the interior of the building varies depending on the outside temperature and humidity, so that the temperature and humidity of the building can be adjusted by reflecting this.

In calculating the average value of the temperature and humidity values measured at regular time intervals (S2), the temperature and humidity are measured at regular time intervals in measuring the temperature and humidity, and at a predetermined time interval, the time interval is measured. It is a step of calculating the average of the temperature value and the humidity value. Temperature and humidity measurements can be controlled more precisely with smaller time intervals. However, the smaller the measurement interval, the more data is accumulated and the larger the storage space, and a higher performance processor is required to process the data. Therefore, the data is measured at a small measurement interval, and the average value of the measured data values is calculated to increase the accuracy of the data.

Determining the average value and then deleting the data before the time point for obtaining the average value (S4) is a step of deleting the measured values of temperature and humidity used to obtain the average value. By using the measured value to calculate the average value, leaving only the calculated average value and deleting the remaining measured value can not burden the capacity of the database, and does not burden the air conditioning control.

The air conditioning control command server receives the temperature, humidity, and air volume control values inputted from the user's PC connected to the Internet connection (S5) in the situation where the air conditioning system controls the temperature and humidity. Allow the air volume to be adjusted. That is, by using the control bar that can adjust the temperature, humidity, air volume of the temperature and humidity control program in the current user's PC shown in Figure 5 to be adjusted to higher, lower than the current temperature, humidity, air volume by the user's adjustment The information is stored in a database.

Computing a total of the selected user's selection value (S6) is a step of calculating the selected total of each view selected in the step S5. By calculating the total, it can be reflected in the temperature and humidity control according to the selected view, so that it can have the best comfort according to the external environment and the user's condition.

Learning to find the temperature and humidity for each situation by using the average value of the temperature and humidity, and the total data of the user's selection value (S8) according to the temperature, humidity, air volume control value selected by the user Adjusting humidity (S81); Storing an external temperature and humidity, a building internal temperature, and a humidity value with respect to a user's selection value (S82); If the value before the user selection is different from the value in step S82, and storing the data value, and to delete the previously stored data value (S83);

In the step S9 of controlling the air conditioning system by the air conditioning control device using the learning data, the temperature and humidity are adjusted by selecting the total using the temperature, humidity, and air volume control values selected by the user.

Referring to the operation and effect of the present invention made of such a configuration and steps as follows.

First, outdoor temperature and humidity, indoor temperature and humidity are measured through a monitoring unit, and the measured values are stored in a database. Shorter time intervals can be used to quickly respond to changes in temperature.

On the other hand, the air conditioning control command server allows the user to directly control using the temperature, humidity, air volume control bar of the temperature and humidity control program installed in the PC using the room connected to the Internet. For example, if it feels colder than the current temperature, move the temperature bar to the (+) direction to increase the temperature, and the user directly adjusts the humidity and air volume of the VAV to send the adjustment value to the HVAC command server for air conditioning. Allow control in the system.

Through the temperature, humidity, air flow control bar as described above, the user can directly adjust, and analyze the data according to the control information for controlling the air conditioner. The generated control information is converted into a protocol used in the network of the air conditioning system through the protocol conversion module and transmitted to the central controller. The central controller receiving the control signal sends a control signal to the digital controller to control the entire air conditioning system. Make sure you have the desired temperature and humidity.

This is because the user's comfort is changed by external factors even under the same temperature and humidity. Therefore, the user can adjust the value directly. It is to control for the best comfort.

For the air conditioning system to have the best comfort control, it is necessary to remember the accumulation of continuous data and temperature and humidity according to external factors so that the next learned control can be applied the next time it encounters an environment with similar external factors. To ensure that Learning becomes more applicable when there is a lot of data and the environment experienced by the controller increases.

That is, by collecting the average of the measured data, the amount of data can be reduced in collecting the data for learning, and the user can optimize the comfort of the user depending on external factors through learning. It is to be able to work in the environment.

It should be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined in the appended claims.
