The number of revolutions of the fan 7 may be high at some density levels among a plurality of density levels. The vane motor 9 may not rotate the vane 8 at a low density level among the plurality of density levels and may rotate the vane 8 at a relatively high density level among the plurality of density levels.

Hereinafter, an example in which the control unit 10 calculates the density level will be described.

The control unit 10 can calculate the average value of the human body count values in a cycle of the set time (for example, 10 minutes) for each set time period (for example, the 1-7 time period).

The human body detection sensor 1 senses the number of the human body at intervals of a predetermined period (for example, one minute) for each set time (for example, 10 minutes) and continues the human body count value to the control unit 10 And the control unit 10 can count the human body count values (for example, 4, 4, 5, 5, 5, 5, 6, 6, and 6) (For example, 5) can be calculated.

The controller 10 continuously increases the average value by more than a predetermined percentage during the preset number of times, and if the room temperature does not reach the desired temperature, the control unit 10 can increase the density level of the set time period by one level. The control unit 10 may store the density level thus calculated in the storage unit 20. The control unit 10 can determine the density level to be 1 if there is no previous density level as in the first density level calculation.

The control unit 10 may lower the density level of the set time period by one level when the average value continuously decreases by more than a predetermined percentage during the preset number of times and the room temperature reaches the desired temperature. The control unit 10 may store the density level thus calculated in the storage unit 20. The control unit 10 may not store the density level in the storage unit 20 when there is no previous density level, such as the lowest density level calculation.

Here, the preset number of times may be set to a predetermined number of times less than six times, such as two or three times, and a predetermined percentage may be set such that the setting% can be 10% or 20%.

For convenience of description, the number of times of setting can be set to three, and the setting% can be set to 20%, but the present invention is not limited to such a numerical value.

For the sake of convenience of explanation, the set time can be set to 10 minutes. In this case, each of the set time zones can have six time zones, and the average value of the human body count values can be calculated during each set time zone have.

Hereinafter, for convenience of explanation, an average value example of the human body count values over time in each of a plurality of set time zones will be described with reference to Table 1.

0 to 10 minutes 10 to 20 minutes 20 to 30 minutes 30 to 40 minutes 40-50 minutes 50 to 60 minutes Satisfaction with temperature condition Density level First time zone 5 5 6 8 10 10 dissatisfaction One 2nd time zone 10 12 15 18 18 18 dissatisfaction 2 3rd time zone 10 12 15 20 17 14 dissatisfaction 3 Day 4 13 12 13 15 11 8 dissatisfaction 3 5th time zone 11 10 8 6 4 4 satisfied 2 Day 6 4 4 3 2 One One satisfied One Day 7 One 2 One One One 0 satisfied One

When the average value of the human body count values is calculated as shown in Table 1, when the first time period has elapsed, the controller 10 continuously increases the average value of the human body count values by at least 20% for three times, Since the room temperature can not reach the desired temperature during the one hour period and the temperature condition is unsatisfactory, the density level can be stored as the first level.

When the second time zone has elapsed, the control unit 10 continuously increases the average value of the human body count values by 20% or more for 3 times during the second time zone. Since the room temperature can not reach the desired temperature during the second time zone, It is possible to store the density level at a second level which is one level higher than the immediately preceding stored level.

When the third time zone has elapsed, the control unit 10 continuously increases the average value of the human body count values by 20% or more for three times during the third time zone. Since the room temperature does not reach the desired temperature during the third time zone, It is possible to store the density level at a third level which is one level higher than the second level stored immediately before the density level.

When the fourth time zone has elapsed, the control unit 10 can not continuously increase the average value of the human body counts by 20% or more for three times or continuously decrease by more than 20% for three times during the fourth time zone, The density level can not be raised or lowered by one level, and the third level, which is the previously stored level, can be maintained regardless of whether or not the room temperature has reached the desired temperature.

  When the fifth time zone has elapsed, the control unit 10 continuously decreases the average value of the human body count values by 20% or more during the third time, and the desired temperature of the room temperature during the fifth time zone And the temperature condition is satisfied, the density level can be lowered from the third level, which is the immediately preceding level, to the second level and stored.

When the sixth time zone has elapsed, the control unit 10 continuously decreases the average value of the human body count values by 20% or more during the third time zone during the sixth time zone. When the room temperature reaches the desired temperature during the sixth time zone, It is possible to store the density level lowered from the previous level, i.e., the second level, to the first level.

When the seventh time zone has elapsed, the control unit 10 determines that the average value of the human body counts during the seventh time zone is continuously increased by 20% or more for three times or continuously decreased by not more than 20% for three times The density level can not be raised or lowered by one level regardless of whether the room temperature has reached the desired temperature during the seventh time zone, and the first level, which is the level immediately before the density level, can be maintained.

The control unit 10 may store the average room temperature, the average desired temperature, the air flow rate, and whether or not the auto swing is performed for each set time zone when storing the density level as described above.

The control unit 10 can execute the learning logic as described above, and after the learning logic as described above is completed, the information learned in the learning logic can be displayed to the user. The control unit 10 can transmit information about the density level, the average room temperature, the average desired temperature, the air volume, and whether or not the auto swing is performed for each set time period on the display, Level, average room temperature, average desired temperature, air volume, and whether or not the auto swing is performed.

The user can confirm the density level of each set time zone by the display and confirm the average room temperature, the average desired temperature, the air volume, and the auto swing of each set time zone in which the density level is stored.

For example, the display may indicate that the first level is displayed on a cooling basis, the average room temperature is 25 占 폚, the average desired temperature is 24 占 폚, and the main use air volume is a paranoid.

Then, the display shows the second level on the cooling reference, the average indoor temperature is 26 캜, the average desired temperature is 24 캜, and the main use air volume is a stale air.

The user can view the information displayed on the display and confirm whether the average room temperature, the average desired temperature, the air flow rate, and the auto swing of each set time zone are set or not. The input unit 3 displays the desired indoor temperature and airflow And whether or not an auto swing is to be input.

The user can input the desired indoor temperature of the first level at 22 deg. C through the input unit 3, input the main usage air volume of the first level as strong wind, input the first level auto swing operation have.

As another example, the user can input the second-level indoor desired temperature through the input unit 3 at 23 ° C, input the second-level main usage air volume with the strong wind, input the second-level auto swing operation can do.

When the user inputs at least one of the desired indoor temperature, air volume and auto swing for each density level to the input unit 3, the control unit 10 controls the input of the user based on the off-gap, air volume, It can be controlled in priority. That is, the control unit 10 can control the compressor 3 according to the desired indoor temperature inputted by the user, taking into account the input by the user without controlling the air conditioner with the control logic set by the learning logic, The fan 7 can be controlled according to the input air volume and the vane motor 9 can be controlled according to the auto swing inputted by the user. The control unit 10 can control the air conditioner with the preference of the user while optimally controlling the air conditioner according to the learning function.

On the other hand, if the user does not input and adjust the desired indoor temperature, air volume, and auto swing of each density level through the input unit 3, the control unit 120 sets the density level calculated for each set time zone and the density level The air conditioner can be controlled according to the thermo-off gap, air volume, and auto swing.

The control unit 120 may control at least one of the thermo-off gap, the air flow rate, and the auto swing state for each of the dense levels during operation after the set learning period.

Hereinafter, examples of the density level, the thermo-off gap, the air flow rate, and the auto swing status will be described.

First, the first level can be set to 2 占 폚 by adding 1 占 폚 to the thermo-off gap when the thermo-on gap is 1 占 폚 and the thermo-off gap is 1 占 폚 before the learning logic is implemented, The air volume can be set to the main usage air volume (for example, a stroke).

The second level, like the first level, has a thermo-on gap of 1 占 폚 and a 1 占 폚 thermo-on gap before the learning logic is implemented, adding 1 占 폚 to the thermo-off gap, And the air volume can be set to a higher air volume (for example, strong wind) than the main air volume (for example, the parallax).

The third level, like the first level, is 1 ° C before the implementation of the learning logic, and when the thermo-off gap is 1 ° C, 1 ° C is added to the thermo-off gap to increase the thermo- And the air flow rate can be set to a higher air flow rate (for example, strong wind) than the main air flow rate (for example, a stroke), and can be set to perform an auto swing operation.

The fourth level can be set to 3 캜 by adding 2 캜 to the thermo-off gap when the thermo-on gap is 1 캜 and the thermo-off gap is 1 캜 before the execution of the learning logic, (For example, strong wind) higher than the main usage air volume (for example, the parallax), and can be set to perform the auto swing operation.

The fifth level can be set to 3 DEG C by adding 2 DEG C to the thermo-off gap when the thermo-on gap is 1 DEG C and the thermo-off gap is 1 DEG C before the execution of the learning logic, It can be set to a power air flow rate which is a maximum air flow rate, and can be set to perform an auto swing operation.

When a plurality of density levels are stored in the storage unit 20, a plurality of density levels may be set to have larger thermo-off gaps than density levels where some density levels are different.

When a plurality of density levels are stored in the storage unit 20, a plurality of density levels can be set to be larger than a density level of some dense levels at different density levels.

When a plurality of density levels are stored in the storage unit 20, a plurality of density levels may include an auto swing operation only at a certain density level, and other density levels may be set to not include an auto swing operation.

When a plurality of density levels are stored in the storage unit 20, the highest density level among the plurality of density levels may be set to be an auto-swing operation with a thermo-off gap of 3 ° C or more and an air volume of the maximum air volume.

On the other hand, when controlling the air conditioner according to the density level, the control unit 10 calculates the average indoor temperature, the average desired temperature, the thermo-off gap determined by the density level, The compressor 5, the fan 7 and the vane motor 9 can be controlled by reflecting the amount of air flow and whether or not the auto swing is occurring.

The control unit 10 can control the air conditioner in consideration of the density level calculated on a specific day from the next day of the specific day on which the density level is calculated and calculate the density level calculated in the setting time period of the specific day, The air conditioner can be controlled in consideration of the average desired temperature, the average room temperature, and the auto swing pre-stored in the air conditioner.

For example, the density level for the first time zone on June 1 is calculated, and the average room temperature, average desired temperature, air volume, and auto swing status during the first time zone are calculated together with the density level , The control unit 10 controls the air conditioning unit 20 to reflect the average room temperature stored in the storage unit 20 in the first time period on June 2, the average desired temperature, Can be controlled. Here, the first time zone of June 2 may be the same time zone as the first time zone of June 1, which is the time at which the density level was calculated.

For example, when the average desired temperature in the first time zone on June 1 is 22 ° C, the main usage air volume in the first time zone on June 1 is a stroke, and the auto swing operation is performed in the first time zone on June 1 When the density level of the first time zone on June 1 is calculated and stored as the first stage, the control unit 10 determines that the average desired temperature in the first time zone on June 2 is 22 ° C, And the thermo-off gap in the first time zone on June 2 is 2 DEG C, so that the air conditioner can be controlled so that the auto swing operation is not performed in the first time zone on June 2. The control unit 10 can turn off the compressor 5 when the temperature sensed by the room temperature sensor 4 falls to 20 ° C or less during the first time period on June 2nd.

On the other hand, prior to the first time zone on June 2, the user can confirm the density level of the first time zone, the average indoor temperature, the average desired temperature and air volume, and information on whether or not the auto swing is performed through the input unit 2 , The user can determine that it is necessary to adjust at least one of the average desired temperature, the air flow rate, and the auto swing.

The user can input at least one of desired indoor temperature, air volume and auto swing through the input unit 2, and the control unit 20 controls the air conditioner in the first time zone of June 2 can do.

If the user inputs the desired temperature in the room at 21 DEG C, inputs the airflow as a strong wind, and inputs the auto swing operation, the density level calculated in the first time zone of June 1 during the first time zone on June 2 The compressor 5 can be thermally turned off when the temperature sensed by the room temperature sensor 4 is lowered to 19 ° C or lower and the fan 7 is driven in a strong wind in preference to the user input inputted through the input unit 3. [ And the vane motor 9 can be driven in the swing mode.

Regarding the second time zone to the seventh time zone, it is possible to control the air conditioner in consideration of the density level calculation, the control of the air conditioner according to the calculated density level and the user input in the first time zone, Its detailed description is omitted in order to avoid redundant description.

4 is a flowchart illustrating an operation of the air conditioner according to the embodiment of the present invention.

The operation method of the air conditioner according to the present embodiment includes a density calculation step S1 for sensing a human body during a set learning period and calculating a density level; (S2) (S3) (S4) for controlling the air conditioner so that at least one of the thermo-off gap, the air flow rate, and the auto swing state is different for each density level after the set learning period.

The density calculating step S1 may be a learning logic for learning the density level of the air conditioning room R to be air conditioned by the air conditioner and the control steps S2, S3, and S4 may be performed in accordance with the density level learned in the learning logic Lt; / RTI > may be the control logic that controls the harmonics.

If the learning logic of the density calculation step S1 has been performed on a specific day (for example, June 1), the control steps S2, S3, and S4 are performed on the next day (For example, June 2) or a separate start date (for example, June 10) entered by the user through the input unit 3.

The density calculation step S1 may detect the human body during the set learning period and calculate the density level according to the count value of the human body sensed for each set time period of the set learning period and whether the room temperature reaches the desired temperature.

The density calculation step S1 may include an average value calculation process for calculating an average value of the human body count values at a set period of time for each set time period during the set learning period.

The density calculation step S1 may further include a density calculation process of calculating a density according to an average value calculated by the average value calculation process and whether or not the room temperature reaches a desired temperature.

In the density calculation process, the average value calculated by the average value calculation process continuously increases by more than a predetermined percentage during the set number of times, and when the room temperature does not reach the desired temperature, the density level of the set time period can be raised by one level.

In the density calculation process, the average value calculated by the average value calculation process continuously decreases by more than a predetermined percentage during the set number of times, and when the room temperature reaches the desired temperature, the density level in the set time zone can be lowered by one level.

The control steps S2, S3, and S4 may control at least one of the thermo-off gap, the air flow amount, and the auto swing state depending on the dense level during the air conditioner operation after the set learning period.

The control steps S2, S3, and S4 are performed to control at least one of the thermo-off gap, the wind amount, and the auto swing state for each dense level differently, If at least one of the desired temperature, air volume, and auto swing is adjusted, the user can control the air conditioner in preference to off-gap, air volume, and auto swing set for each density level. )

On the other hand, if the user does not adjust and input at least one of the desired indoor temperature, air volume, and auto swing at each density level after the density calculation step S1, the control steps S2, S3, The air conditioner can be controlled on the basis of the separately set thermo-off gap, air volume, and auto swing (S2) (S3)
