Description

Air conditioning control system {AIR CONDITIONING CONTROL SYSTEM}

The present invention relates to an air conditioning control system.

An air conditioner is a device for maintaining the air in a predetermined space in the most suitable state according to the use and purpose. In particular, the internal refrigerant undergoes a phase change while circulating through the compressor, the condenser, the expander, and the evaporator.

In general, the air conditioner includes a compressor, a condenser, an expansion device, and an evaporator, and a refrigerant cycle for performing compression, condensation, expansion and evaporation of the refrigerant is driven to cool or heat the predetermined space. .

The predetermined space may be variously proposed according to a place where the air conditioner is used. For example, when the air conditioner is disposed in a home or office, the predetermined space may be an indoor space of a house or a building. On the other hand, when the air conditioner is disposed in a vehicle, the predetermined space may be a boarding space in which a person rides.

When the air conditioner performs a cooling operation, the outdoor heat exchanger provided in the outdoor unit functions as a condenser, and the indoor heat exchanger provided in the indoor unit functions as an evaporator. On the other hand, when the air conditioner performs a heating operation, the indoor heat exchanger functions as a condenser and the outdoor heat exchanger functions as an evaporator.

Meanwhile, in the case of the conventional air conditioner, cooling or heating operation can be performed to maintain the indoor temperature according to the desired temperature set by the occupants. Recently, in order to satisfy the thermal comfort of the occupants, human life Based on the data index estimated and calculated by reflecting the thermal environment factors of the space (e.g., temperature, humidity, airflow, radiant temperature, occupant's clothing amount, metabolic rate, etc.), the temperature and humidity of the room can be controlled. There is a function.

The invention related to the existing air conditioning control system is disclosed as follows.

However, the invention such as the existing air conditioning control system has the following problems.

In the case of Asian countries such as Korea and Japan, a floor culture of living on the floor is being implemented instead of a bed culture of living in a bed as in the West. In particular, in the case of Korea, a representative floor-type residential culture called Ondol is formed. For example, a boiler for heating the floor is formed in an apartment or house, and most people take off their shoes and live on the floor. Traditionally, a culture suitable for floor life is formed.

In addition, since Korea or Japan belongs to the floor living culture, the floor temperature has a great influence on the user's sensible temperature. In fact, in the case of winter, even if the internal temperature is warm, when the floor is cold, the actual user's sensible temperature is felt low.

However, in the case of the conventional air conditioning control system, there is a problem in that the temperature of the internal air is not controlled by considering the actual floor temperature as a thermal environment factor.

In addition, even if the air conditioner is actually controlled in consideration of the warm environmental factors excluding the temperature of the floor, there is a problem in that the internal air cannot be controlled as much as the desired temperature in the floor living culture.

That is, when the temperature difference between the floor temperature and the indoor air is large, there is a problem in that it is difficult to give a desired comfort to the occupant. For example, when the temperature of the floor is high while the temperature of the indoor air is relatively high, the occupant may feel the heat due to the temperature of the floor even though the temperature of the indoor air is low.

However, the conventional air conditioning control system mainly controls the temperature and humidity based on the indoor air temperature, so it is difficult to provide comfort to the occupants.

The present invention has been proposed to solve the above problems, and an object of the present invention is to control the air conditioner by considering the floor temperature as a thermal environment factor of the air control.

Another object of the present invention is to control the wind direction discharged from the air conditioner according to the distance between the air conditioner and the floor as well as the temperature of the floor.

In addition, by considering the temperature of the floor, it is an object of the present invention to allow users living in a floor living culture to live in a more comfortable environment.

In addition, when a plurality of indoor units are connected by communication, the object of the present invention is to allow a nearby indoor unit to control the wind direction by comparing the distance between the plurality of indoor units with the corresponding location where the floor temperature is measured.

The air conditioning control system according to an embodiment of the present invention includes: a movement sensing device capable of driving in an indoor space and storing floor temperature data of the indoor space; and an air conditioner that is connected to communication with the movement sensing device and can control a wind direction or an air volume of the discharge air using the floor temperature data, through which the air in the indoor space can be adjusted based on the floor temperature data value. can

In addition, according to an embodiment of the present invention, there is provided a method for controlling an air conditioner, comprising: a communication step in which a robot cleaner and an indoor unit of the air conditioner are communicatively connected; a position and temperature measurement step in which the robot cleaner automatically cleans while traveling in the cleaning target area, and measures the position and floor temperature of the cleaning completion area; a transmitting step of transmitting, by the robot cleaner, the measured position data and floor temperature data to the indoor unit; a temperature comparison step of comparing the floor temperature for each location based on the location data and the floor temperature data received by the indoor unit; and a wind direction control step of controlling the wind direction so that the wind is discharged to a location having a high floor temperature as a result of comparison.

According to the air conditioning control system according to the embodiment of the present invention having the configuration as described above, the following effects are obtained.

First, considering the temperature of the floor as a thermal environment factor of the air control, there is an effect of controlling the wind direction and the air volume of the air conditioner.

Second, by controlling the wind direction and air volume according to the floor temperature, there is an effect that the user can live in a more comfortable indoor environment in the floor living culture.

In particular, as the air conditioning control system that can respond to the temperature change of the floor by varying the air volume over time while allowing the wind to be discharged to a high-temperature area, is disclosed, there is an effect of giving comfort to the occupants.

Third, even when a plurality of indoor units are communicated with the robot vacuum cleaner, the indoor units placed close to the corresponding position receive the floor temperature data of the corresponding position and operate, thereby reducing power wastage and increasing the cooling efficiency. have.

The temperature comparison unit 24 may compare the floor temperature data of each of the divided left area A1 and the right area A2 based on the mapping data (S42). In detail, the temperature comparison unit 24 compares the floor temperature of the left area A1 with the floor temperature of the right area A2 to compare which area has the highest temperature, and compares the result of the comparison with the control unit 21 . can be sent to

It is possible to issue a control command to operate (S51). That is, the vertical vane driving unit 27 may operate to rotate the vertical vane 32 to the left with respect to the front surface of the main body 34 of the indoor unit 2 by the control unit 21 . As the vertical vane 32 rotates to the left, the indoor unit 2 can control the airflow so that the wind is discharged in the left direction, and accordingly, the temperature drop value of the left area A1 is decreased in the right area A2. may be greater than the temperature drop of

The control unit 21 of the indoor unit 2 controls the operation of the horizontal vane driving unit 26 according to the result of the comparison received from the temperature comparator 24, that is, in which region the temperature is high, so that the discharge is performed. You can control the wind direction.

In detail, when the floor temperature of the near area A3 is higher than the floor temperature of the far area A4 (S 47), the control unit 21 determines that the horizontal vane driving unit 26 moves the horizontal vane 31 to the horizontal vane 31. A control command may be given to provide power to rotate downward (S53). That is, the horizontal vane driving unit 26 may operate to rotate the horizontal vane 31 downward with respect to the front of the main body of the indoor unit 2 by the control unit 21 . As the horizontal vane 31 rotates downward, the indoor unit 2 can control the airflow so that the wind is discharged in the downward direction. It may be larger than the temperature drop value of A4).

Conversely, when the bottom temperature of the remote area A4 is higher than the bottom temperature of the near area A3 (S48), the control unit 21 determines that the horizontal vane driving unit 26 controls the horizontal vane 31 . It is possible to give a control command to provide power to rotate upward (S54). In detail, the horizontal vane driving unit 26 may operate to rotate the horizontal vane 31 upward with respect to the front of the main body 34 of the indoor unit 2 by the control unit 21 . That is, as the horizontal vane 31 rotates upward, the indoor unit 2 can control the airflow so that the wind is discharged in the upward direction. It may be larger than the temperature drop value of A3).

In the above example, the robot cleaner 1 and the indoor unit 2 divide the space into the left area A1 and the right area A2, or divide the space into the near area A3 and the far area A4. However, the present invention is not limited thereto, and the indoor unit 2 combines the left, right, near and far areas A1, A2, A3, and A4 through location data to compare the floor temperature data of each area, and then The vertical and horizontal vanes 31 and 32 can be controlled.

In detail, the photographed area may be stored in the memory unit 17 by the photographing device 12 of the robot cleaner 1, and the temperature sensor 16 of the robot cleaner 1 measures The bottom temperature of the entire photographed area may be stored in the memory unit 17 , respectively.

In addition, the position data stored in the memory unit 17 of the robot cleaner 1 and the floor temperature data at the position are transmitted to the indoor unit 2, and the indoor unit 2 receives the received position data and floor By controlling the horizontal vane 31 and the vertical vane 32 based on the temperature data, the wind direction of the discharged wind can be adjusted.

In the above description, the air conditioner divides the indoor space into left and right areas and/or front and rear areas to discharge air.

Hereinafter, a method of controlling the air volume of the air conditioner will be described in detail.

8 is a flowchart illustrating a step of controlling the air volume of the air conditioner according to an embodiment of the present invention, and FIG. 9 is a flowchart illustrating a specific method of controlling the air volume of the air conditioner according to an embodiment of the present invention.

8 and 9 , a second setting period may be stored in the memory unit 17 of the robot cleaner 1 . Also, while the indoor unit 2 is being driven, the mapping data may be transmitted to the indoor unit 2 every second set period.

For example, if it is assumed that the second set period is 30 minutes, the robot cleaner 1 transfers the mapping data obtained by mapping the location data of the indoor space and the floor temperature data to the indoor unit 2 at intervals of 30 minutes. can be transmitted In this case, the indoor unit 2 may adjust the amount of air discharged based on the mapping data received every second set period.

In detail, the robot cleaner 1 may first measure the mapping data of the indoor space (S110), and transmit the measured primary mapping data to the indoor unit 2 (S120). In this case, the indoor unit 2 may discharge air into the indoor space at a first air volume based on the firstly transmitted mapping data ( S130 ). In addition, when the second setting period elapses (S140), the robot cleaner 1 secondarily measures the changed secondary mapping data of the indoor space (S150), and converts the measured secondary mapping data to the indoor unit ( 2) can be transmitted (S160). The indoor unit 2 may discharge air into the indoor space at a second air volume that is the same as or changed to the first air volume based on the secondly transmitted mapping data (S170). Also, if the indoor unit is turned off (S180), the process may be terminated. Otherwise, the robot cleaner may repeatedly measure and transmit the mapping data for each second set period to the indoor unit, and transmit the data to the indoor unit. Air volume can be controlled based on the received mapping data.

In more detail, the control unit 21 of the indoor unit 2 compares the firstly transmitted primary mapping data with the floor temperature data stored in the secondly transmitted secondary mapping data with each other, and the change value of the floor temperature data can be measured (S171).

Also, a preset temperature difference value may be stored in the memory unit 25 of the indoor unit 2 . In this case, the controller 21 of the indoor unit 2 may change the change amount of the first air volume based on whether the change value of the floor temperature data is greater than or less than the preset temperature difference value.

In detail, when the change value of the floor temperature data exceeds the preset temperature difference value (S172), the control unit 21 of the indoor unit 2 may discharge a second air volume with a reduced change amount of the first air volume. (S173), when the change value of the floor temperature data is less than the preset temperature difference value (S174), a second air volume having an increased change amount of the first air volume may be discharged (S175).

In addition, when the change value of the floor temperature data is the same as the preset temperature difference value, the second air volume S176 equal to the first air volume may be discharged.

For example, it is assumed that the indoor unit 2 performs a cooling operation, the second setting period is 30 minutes, and the preset temperature difference value is 3 degrees. In this case, the robot cleaner 1 primarily transmits the mapping data of the indoor space to the indoor unit 2, and the indoor unit 2 transmits the firstly transmitted mapping data to the indoor space. Air may be discharged by medium wind, which is the first air volume. In this state, when 30 minutes have elapsed, the robot cleaner 1 may secondarily transmit the mapping data obtained by re-mapping the floor temperature data and location data of the indoor space to the indoor unit 2 .

At this time, in the control unit 21 of the indoor unit 2, the floor temperature value of an arbitrary area of the firstly transmitted mapping data is 18 degrees, and the floor of the arbitrary area of the secondly transmitted mapping data When the temperature value is 17 degrees, the floor temperature change value is 1 degree, which is less than 3 degrees which is the preset temperature difference value, so that air may be discharged at a second air volume in which the first air volume is increased to a strong wind.

Conversely, if the floor temperature value of an arbitrary area of the firstly transmitted mapping data is 18 degrees, but the floor temperature value of the arbitrary area of the secondly transmitted mapping data is 14 degrees, the floor temperature change value is 4 and, since it exceeds the preset temperature difference value of 3 degrees, air may be discharged at a second air volume obtained by reducing the first air volume to a weak wind.

Through this, by adjusting the amount of air discharged from the indoor unit 2 according to the floor temperature data of the indoor space at every second set period, there is an effect that the occupant can feel more comfortable.

Hereinafter, a case in which a plurality of indoor units are disposed in an area requiring air conditioning will be described.

10 is a schematic diagram illustrating a case in which a plurality of indoor units are interlocked in the air conditioning control system of the present invention.

Referring to FIG. 10 , the robot cleaner 1 may further include a distance comparison unit 20 . In detail, when a plurality of indoor units 2 are disposed in an area requiring air conditioning, and a plurality of indoor units 2 are communicatively connected to the robot cleaner 1, the distance comparator 20 is configured for each indoor unit 2 ) and the distance between the cleaned area measured by the robot cleaner 1 is compared.

In detail, an example in which one robot cleaner 1 and the first indoor unit 3 and the second indoor unit 4 are disposed in the air conditioning space will be described in detail. In this case, the configuration of the first indoor unit 3 and the second indoor unit 4 may be the same as that of the indoor unit 2 . The separation distance between the first indoor unit 3 and the cleaned area measured by the robot cleaner 1 is D1, and the separation distance between the second indoor unit 4 and the cleaned area measured by the robot cleaner 1 is D2. define.

The second communication unit 15 of the robot cleaner 1 searches for an indoor unit that is powered on among the first indoor unit 3 and the second indoor unit 4 . When power is turned on to both the first indoor unit 3 and the second indoor unit 4 , the second communication unit 15 communicates with the communication unit of the first indoor unit 3 and the communication unit of the second indoor unit 4 . All can be communicatively connected.

In this state, the robot cleaner 1 may perform cleaning, and while cleaning is in progress, location data for the cleaned area and floor temperature data at each location may be collected and stored in the memory unit 17 .

In addition, the distance comparison unit 20 of the robot cleaning unit 1 includes a separation distance D1 between the position data for each cleaning completed area and the first indoor unit, and a separation distance D2 between the position data and the second indoor unit. ) can be compared.

As shown in FIG. 10 , when D1 is shorter than D2, the robot cleaner 1 may transmit location data and floor temperature data in the corresponding cleaning completed area to the first indoor unit 3, and the first indoor unit ( 3) can control the airflow based on the received location data and floor temperature data. In this case, the second indoor unit 4 may be operated in the same manner as in the conventional operation.

Conversely, when D1 is longer than D2, the robot cleaner 1 may transmit the location data and floor temperature data in the corresponding cleaning completed area to the second indoor unit 4, and the second indoor unit 4 Airflow can be controlled based on the received location data and floor temperature data. In this case, the first indoor unit 3 may be operated in the same manner as in the conventional operation.

That is, even when a plurality of indoor units are disposed in a house or an interior space, the distance between the cleaning completed area and the indoor unit is compared and only the closest indoor unit can control the temperature according to the floor temperature, so that the plurality of indoor units can be duplicated. It has the effect of preventing power wastage due to operation.
