According to the air cleaning and energy reduction system according to the present invention, by utilizing various sensors to detect the amount of carbon dioxide, dust particles or harmful gas to operate the ventilation fan 110 to purify the air, by the temperature sensor 144 The heater 120 and the air conditioner 130 are operated to maintain a preset temperature, and the energy is reduced by reducing heat loss by opening and closing a blind or curtain by the blind / curtain driver 180, and a humidity sensor 145. The humidifier 160 and the dehumidifier 170 are operated in the dry season and the rainy season so as to be the optimal conditions for living by) to reduce energy loss by maintaining the optimum humidity and the optimum temperature.

In addition, in order to implement these functions, receiving a control signal from the control unit (150, 250) ventilation fans (110, 120), heaters (120, 220), air conditioners (130, 230), humidifiers (150, 260), dehumidifiers (170, 270) and the blind / curtain driving unit (180, 280) By modularizing the devices to control), it can be easily installed without major changes to the existing building.

The controller 150 compares the amount of carbon dioxide detected by the carbon dioxide sensor 141 with a preset value and operates the ventilation fan 110 to lower the amount of carbon dioxide within the set value range when the detected value is higher than the set value range. . In addition, when the smoke is detected by the smoke sensor 142, the control unit 150 operates the ventilation fan 110 to lower the amount of smoke within the set value range. In addition, the controller 150 compares the amount of dust detected by the dust sensor 143 with a preset value, and when the detected value is higher than the set value, operates the ventilation fan 110 to set the amount of fine particles of the dust in the set value range. Lower to within.

The controller 150 compares the temperature value detected by the temperature sensor 144 with a preset temperature value, and if the detected temperature value is higher than the set temperature value, the controller 150 blinds the white color by the blind / curtain driver 180 when it is low. Or hit the curtain of the height color to block the outside temperature, if the temperature does not go below the set value even after a certain time to operate the air conditioner 130 to lower the temperature within the set value range. In addition, when the outside temperature is lower than the set temperature, the controller 150 strikes a black blind or black curtain to absorb solar heat, thereby raising the room temperature, and when the set temperature does not reach the set temperature even after a predetermined time, the heater ( 120) to raise the temperature. On the other hand, the controller 150 may increase the temperature within the set value range by operating the heating regardless of the blind or curtain at night.

If the humidity value detected by the humidity sensor 145 is higher than the preset humidity value, the controller 150 operates the dehumidifier 170 to lower the humidity within the set value range, and the detected humidity value is lower than the preset humidity value. If it is to operate the humidifier 160 to raise the humidity value within the set value range.
