The present invention relates to the control of indoor air, and more specifically, to an indoor environment that allows an integrated controller to efficiently manage an indoor air environment by controlling an electrothermal exchange ventilator, an air conditioner, a humidifier dehumidifier, and a lamp according to indoor air conditions. An integrated controller of a control system.

In general, the air in an enclosed space increases the content of carbon dioxide (CO ₂ ) over time due to the breathing of the inner chamber, which interferes with the breathing of the inner chamber.

Therefore, when a lot of people stay in a narrow space such as an occupancy space such as an apartment, an office or a vehicle, the indoor polluted air should be replaced with fresh air of the outside at any time.

As air pollution increases, the importance of the human breathing environment becomes more and more important, and various efforts are being made to maintain a more comfortable indoor environment instead of simply ventilating indoors.

Hereinafter, with reference to the accompanying drawings will be described with respect to the change characteristics of the indoor air environment and the problems and the ventilation system of the prior art.

Figure 1 is a graph showing the carbon dioxide-oxygen change characteristics during bedtime, Figure 2 is a table showing the carbon dioxide generation characteristics by the human body.

3 is a table of conversion of annoyance index for each temperature and humidity.

Indoor air quality is determined by carbon dioxide, which is caused by many factors, such as human breathing, heating appliances, burning of kitchen appliances, and burning.

Of course, in addition to the amount of carbon dioxide, the air quality of the room is determined by the humidity and temperature. First, the generation of carbon dioxide and its effects on the human body will be described.

Carbon dioxide may be generated by breathing even during sleep of a person, as shown in FIG. 1, when the amount of oxygen decreases while the carbon dioxide increases during sleep, adversely affects the health of the sleeping person.

Figure 2 shows the amount of carbon dioxide generated by the human body, the amount of carbon dioxide generated after 6 hours when two people go to bed in the bedroom or room of 5 pyeong without ventilation is 4,000ppm.

And if three people are occupied without ventilation in a 10-pyeong office, the amount of carbon dioxide generated after 2 hours is 1,500 ppm.

In such a vehicle, the increase in the amount of carbon dioxide is more severe.

Abnormal symptoms shown to human by such carbon dioxide are shown in Table 1.

CO2 concentration (ppm) Symptom Remarks 350-450 Normal atmospheric concentration Outside air 1000 Ventilation standards Air quality management standard 1500 Mild metabolic disorders, learning ability, low concentration, mild headache  Lack of oxygen and abnormal oxygen balance in the blood 4000 Chest tightness, shortness of breath, headache More than 7000 Normal activity difficulties

In order to solve the problems caused by the increased concentration of carbon dioxide in the room, a ventilation system is used.

In general, the ventilation system drives an air supply fan to introduce outdoor air, and cools and heats the incoming air to a temperature similar to the room temperature through the heat exchanger, and then enters the air through the air supply.

In addition, the exhaust fan is driven to allow the indoor air to flow through the exhaust unit, and the incoming air is exhausted to the outside. At this time, the total heat exchanger serves to suppress the sudden inflow of cold air and heat.

The indoor air quality can be determined not only by the amount of carbon dioxide, but also by humidity and temperature. According to the Ministry of Environment's indoor air quality management data, preferred temperature and humidity maintenance standards are as follows.

Maintaining temperatures are 24 ° C to 28 ° C and 60% humidity in summer, 19 ° C to 23 ° C and 50% humidity in spring and autumn, and 18 ° C to 20 ° C and 40% humidity in winter. .

If such temperature and humidity are not maintained, the discomfort index felt by the insider becomes high.

According to the conversion table of the temperature and humidity of the Korea Health Care Association of FIG. 3, it is indicated that maintaining less than 75 is a pleasant environmental condition.

If the index is 86, the degree of discomfort is very unpleasant, and in the case of index 83, the power is unpleasant, and if the index is 80, about 50% is unpleasant, and if the index is 75, about 10% is unpleasant. It is a feeling.

In order to maintain such a comfortable environment, it can be seen that proper maintenance of temperature and humidity as well as exhaust of carbon dioxide is required.

The ventilation system and the humidity and temperature maintaining apparatus of the prior art for the proper maintenance of such exhaust, temperature, humidity of carbon dioxide has the following problems.

Ventilation systems that automatically ventilate according to the indoor air condition are introduced, and systems for maintaining temperature and humidity have been constructed and used, but these systems are individually operated to increase user inconvenience.

That is, there is a hassle to control each system separately, there is a problem that can not maintain the indoor air quality of the degree desired by the user by a simple setting operation.

In particular, the control devices (main body control means or remote controller, etc.) of the respective devices for controlling the indoor air are separated for each device so that the user inputs control signals individually as needed.

In addition, automatic operation by a setting program instead of a user's input is also performed for each device, so proper device operation required for improving indoor air quality is difficult.

The sensors of the sensor unit include the temperature sensor 44a, the CO ₂ sensor 44b, the humidity sensor 44c, the VOC sensor 44d for sensing air pollution by volatile organic compounds, and the dust concentration in the air. The dust sensor 44e and the health care sensor 41 for sensing the state of the body temperature, pulse, etc. by the user's contact may be all configured, but the type and number of the sensor may be different Of course.

Even if the number and type of sensors are reduced, it is preferable to include a temperature sensor 44a, a CO ₂ sensor 44b, and a humidity sensor 44c to smoothly control the indoor air environment.

Here, in the dry-in mode, when the ventilation fan of the kitchen or the ventilation fan of the bathroom is operated, the main ventilation system, which is one of the indoor environment control devices, is driven by the control of the indoor environment control unit 43.

Dry-out mode automatically activates the kitchen's ventilation fan or the bathroom's ventilation fan when the main ventilation system, which is one of the indoor environment controls, is driven.

The dry-in / dry-out mode is intended to solve the problem that the air quality of the entire room is not easily improved by partial ventilation, and is automatically executed or stopped by user input. It is set to be.

Here, the sensors for fire detection and alarm for each room is not limited to the carbon dioxide concentration sensor, the temperature sensor, it is obvious that other types of sensors may be provided and used.

First of all, in order to prevent malfunction of the fire detector, even if the fire detector determines that a fire has occurred, a carbon dioxide concentration sensor and a temperature sensor provided in the integrated controller by communication through a home network controller (increased carbon dioxide concentration and temperature rise when a fire occurs) In the event that it is determined that the fire is certain by using the sensing value of the sensor), a fire alarm is taken to solve the problem caused by the malfunction of the fire detector.

In addition, it is possible to detect and alarm a fire on its own by using a sensing result using a carbon dioxide concentration sensor and a temperature sensor provided in the integrated controller without depending on the detection result of the generation / floor installed fire detector.

This makes it possible to detect fire by room without having to install a fire detector in each room, which is advantageous in terms of cost.

The wired / wireless communication module 48 includes a wireless communication module such as a Zigbee communication module or a wired communication module such as a PLC communication module. The wired / wireless communication module 48 enables communication with a home network main controller to provide information about an indoor environment. In addition to increasing the possibility of use, it should be possible to respond to the following emergencies.

In addition, when a fire is detected, it is also possible to automatically notify the fact that a fire has occurred in the guard room, the apartment management room, and the fire station through the home network main controller in addition to the sound or alarm alarm.

Specifically, the operation mode using the indoor environment control system and its integrated controller according to the present invention will be described.

Ventilation operation mode for improving the indoor air quality according to the present invention comprises a large 'normal ventilation mode', 'electric heat exchange mode', 'automatic ventilation mode', 'sleep mode'.

First, 'Normal ventilation mode' is a manual ventilation control mode using indoor environment control devices according to the user's operation setting conditions. By controlling the air volume (weak → medium → strong) and the 'timer button' input 'Off reservation' can be made in hours.

In addition, 'electric heat exchange mode' is controlled by interlocking with main electric heat exchange system among indoor environment control devices by RS-485 communication.If the temperature is kept below the standard setting value for a certain time, 'warning' is checked. In case of heating and heating, or if the room temperature is above the standard setting value for a certain time, 'warning' is generated and cooling operation is performed.

Likewise, the 'heat exchange mode' can be controlled by the input of the 'operation button' (weak → medium → strong), and if the room temperature does not change over a certain time during the reference time, It is preferable to stop the operation of the total heat exchange mode and not to drive the ventilation system.

In addition, the 'automatic ventilation mode' operates based on the concentration of carbon dioxide (CO ₂ ), which is a measure of indoor air quality, so that the concentration of carbon dioxide maintains a specific reference concentration.

The reference concentration is preferably set to 1000 ppm.

When the operation of the 'automatic ventilation mode' as described above, it is preferable that the air volume is set to be automatically adjusted by a three-step table as shown in Table 2.

Stage 1 Tier 2 Tier 3 River More than 1200 River 1100 or more River More than 1000 medium 1100 ~ 1199 medium 1000-1099 medium 900-999 about 1000-1099 about 900-999 about 800 ~ 899

Similarly, in the case where the air flow is 'strong' and the reference time is extended for a long time, it is preferable to stop the operation of the 'automatic ventilation mode' and not to operate the ventilation system in order to protect the indoor environment control device.

In addition, the 'sleep mode' is set to time by setting the airflow intensity of the ventilation system to 'weak'. When the 'sleep mode' ends, the 'sleep mode' is switched to the 'automatic ventilation mode'.

In 'Normal Ventilation Mode' and 'Heat Exchange Mode', 'Off Scheduled Operation' is possible.If there is a timer key input regardless of the operation or stop of the current mode, it switches from the current mode to the stop mode and If there is an operation input within a certain time after the key is pressed, operate the corresponding operation mode for the set time and stop.

When the mode switching between the 'normal ventilation mode', 'heat exchange mode', 'automatic ventilation mode' and 'sleep mode' described above is performed, the setting value of each mode should be initialized at the time of mode switching, The stored automatic ventilation concentration table maintains its final state.
