Air conditioner including lighting and control method thereof

[0001] One embodiment of the present disclosure relates to an air conditioner including lighting, a method for controlling the air conditioner, and a computer-readable recording medium having recorded thereon a program for performing the air conditioner control method on a computer.

[0002] Various types of air conditioners are widely used in indoor spaces. Air conditioners can be equipped with various sensors, such as occupancy sensors, light sensors, and temperature sensors. These sensors can be used to regulate the environment of the air-conditioned space and control its operation. Furthermore, if an air conditioner includes lighting, it can utilize this lighting to provide various functions. However, if the lighting is used solely for indoor lighting, the utility of the lighting is reduced.

[0003] According to one aspect of one embodiment of the present disclosure, an air conditioner is provided. The air conditioner includes a detection sensor for detecting an object, a light sensor for detecting illuminance of a target space, lighting, an air conditioning module including a compressor, at least one processor including a processing circuit, and a memory storing at least one instruction, wherein the at least one instruction, when individually or collectively executed by the at least one processor, causes the air conditioner to determine whether an illuminance value detected by the illuminance sensor is equal to or greater than a first illuminance reference value, detect a person from the target space using a sensor detection value of the detection sensor, and control the lighting in a first mode that controls at least one of an illuminance or an illuminance change pattern of the lighting based on a compressor frequency of a compressor of the air conditioning module when the detected illuminance value is equal to or greater than the first illuminance reference value and a person is detected in the target space.

[0004] In addition, according to one aspect of one embodiment of the present disclosure, a method for controlling an air conditioner is provided. The method for controlling an air conditioner includes the steps of detecting an illuminance value of a target space using an illuminance sensor, determining whether the detected illuminance value is equal to or greater than a first illuminance reference value, detecting a person from the target space using a sensor detection value of a detection sensor, and controlling the air conditioning module in a first mode that controls at least one of an illuminance or an illuminance change pattern of lighting included in the air conditioner based on a compressor frequency of a compressor of the air conditioning module when the detected illuminance value is equal to or greater than the first illuminance reference value and a person is detected in the target space.

[0034] When we say that a component is “on” another component, this includes not only cases where the component is in contact with the other component, but also cases where there is another component between the two components.

[0035] An air conditioner according to one embodiment of the present disclosure is a device that performs functions such as air purification, ventilation, humidity control, cooling, or heating in an air-conditioned space (hereinafter referred to as “indoor”), and means a device having at least one of these functions.

[0036] According to one embodiment of the present disclosure, an air conditioner may include a heat pump device to perform a cooling function or a heating function. The heat pump device may include a refrigeration cycle in which a refrigerant circulates along a compressor, a first heat exchanger, an expansion device, and a second heat exchanger. According to one or more embodiments, components of the heat pump device may be built into a single housing forming the exterior of the air conditioner, such as a window air conditioner or a portable air conditioner. According to one or more embodiments, some components of the heat pump device may be separately built into a plurality of housings forming a single air conditioner, such as a wall-mounted air conditioner, a standing air conditioner, a system air conditioner, etc.

[0037] An air conditioner including a plurality of housings may include at least one outdoor unit installed outdoors (e.g., in a non-air-conditioned space) and at least one indoor unit installed indoors. For example, the air conditioner may be configured such that one outdoor unit and one indoor unit are connected via a refrigerant pipe. For example, the air conditioner may be configured such that one outdoor unit is connected to two or more indoor units via refrigerant pipes. For example, the air conditioner may be configured such that two or more outdoor units and two or more indoor units are connected via a plurality of refrigerant pipes.

[0038] The outdoor unit can be electrically connected to the indoor unit. For example, information (or commands) for controlling the air conditioner can be input through an input interface provided on the outdoor or indoor unit, and the outdoor and indoor units can operate simultaneously or sequentially in response to user input.

[0039] The air conditioner may include an outdoor heat exchanger provided in the outdoor unit, an indoor heat exchanger provided in the indoor unit, and a refrigerant pipe connecting the outdoor heat exchanger and the indoor heat exchanger.

[0040] An outdoor heat exchanger can utilize a phase change (e.g., evaporation or condensation) of the refrigerant to exchange heat between the refrigerant and the outdoor air. For example, while the refrigerant condenses in the outdoor heat exchanger, it releases heat to the outdoor air, and while the refrigerant flowing in the outdoor heat exchanger evaporates, it absorbs heat from the outdoor air.

[0041] Indoor units are installed indoors. For example, indoor units can be categorized into ceiling-mounted, stand-alone, and wall-mounted types depending on their placement. For example, ceiling-mounted indoor units can be categorized into four-way, one-way, and duct-type indoor units depending on how air is discharged.

[0042] Similarly, an indoor heat exchanger can utilize the phase change of the refrigerant (e.g., evaporation or condensation) to exchange heat between the refrigerant and indoor air. For example, while the refrigerant evaporates in the indoor unit, the refrigerant can absorb heat from the indoor air. The cooled indoor air can then be blown through the cooled indoor heat exchanger, thereby cooling the room. Furthermore, while the refrigerant condenses in the indoor heat exchanger, the refrigerant can release heat to the indoor air. By blowing the heated indoor air through the high-temperature indoor heat exchanger, the room can be heated.

[0043] That is, the air conditioner performs a cooling or heating function through a phase change process of the refrigerant circulating between the outdoor heat exchanger and the indoor heat exchanger. To circulate the refrigerant, the air conditioner may include a compressor that compresses the refrigerant. The compressor can suck in refrigerant gas through the suction port and compress the refrigerant gas. The compressor can discharge the high-temperature and high-pressure refrigerant gas through the discharge port. The compressor may be placed inside the outdoor unit.

[0044] The refrigerant may circulate through the refrigerant pipe in the order of a compressor, an outdoor heat exchanger, an expansion device, and an indoor heat exchanger, or in the order of a compressor, an indoor heat exchanger, an expansion device, and an outdoor heat exchanger.

[0045] For example, if an air conditioner has one outdoor unit and one indoor unit directly connected through a refrigerant pipe, the refrigerant may be arranged to circulate between one outdoor unit and one indoor unit through the refrigerant pipe.

[0046] For example, in an air conditioner, if one outdoor unit is connected to two or more indoor units via refrigerant pipes, the refrigerant can flow to multiple indoor units via refrigerant pipes branching from the outdoor unit. The refrigerant discharged from the multiple indoor units can be combined and circulated to the outdoor unit. For example, multiple indoor units can be directly connected in parallel to a single outdoor unit via separate refrigerant pipes.

[0047] Multiple indoor units can operate independently, each according to a user-defined operating mode. That is, some indoor units can operate in cooling mode, while others operate in heating mode. In this case, the refrigerant can be selectively introduced into each indoor unit at either high or low pressure along a designated circulation path via a flow-through valve, described later, and then discharged to the outdoor unit for circulation.

[0048] For example, when an air conditioner has two or more outdoor units and two or more indoor units connected through multiple refrigerant pipes, the refrigerant discharged from the multiple outdoor units may join and flow through a single refrigerant pipe, then branch off again at some point and flow into multiple indoor units.

[0049] Multiple outdoor units may all be operated, or at least some may not be operated, depending on the operating load of the multiple indoor units. In this case, the refrigerant may be introduced into the outdoor unit, which is selectively operated, through a flow switching valve and circulated there. The air conditioner may include an expansion device to reduce the pressure of the refrigerant flowing into the heat exchanger. For example, the expansion device may be located within the indoor unit, the outdoor unit, or both.

[0050] An expansion device can, for example, utilize a throttling effect to lower the temperature and pressure of the refrigerant. The expansion device may include an orifice capable of reducing the cross-sectional area of ​​the flow path. Refrigerant passing through the orifice may experience a decrease in temperature and pressure.

[0051] The expansion device may be implemented as, for example, an electronic expansion valve capable of controlling the opening ratio (the ratio of the cross-sectional area of ​​the valve's flow path when partially open to the cross-sectional area of ​​the valve's flow path when fully open). Depending on the opening ratio of the electronic expansion valve, the amount of refrigerant passing through the expansion device can be controlled.

[0052] The air conditioner may further include a flow diverter valve positioned along the refrigerant circulation path. The flow diverter valve may include, for example, a four-way valve. The flow diverter valve may determine the refrigerant circulation path depending on the indoor unit's operating mode (e.g., cooling operation or heating operation). The flow diverter valve may be connected to the discharge port of the compressor.

[0053] The air conditioner may include an accumulator. The accumulator may be connected to the suction port of the compressor. The accumulator may receive low-temperature, low-pressure refrigerant vaporized in an indoor heat exchanger or an outdoor heat exchanger.

[0054] The accumulator can separate the refrigerant liquid from the refrigerant gas when a refrigerant mixture of refrigerant liquid and refrigerant gas is introduced, and provide the refrigerant gas from which the refrigerant liquid has been separated to the compressor.

[0055] An outdoor fan may be installed near the outdoor heat exchanger. The outdoor fan may blow outdoor air to the outdoor heat exchanger to promote heat exchange between the refrigerant and the outdoor air.

[0056] The outdoor unit of the air conditioner may include at least one sensor. For example, the sensor of the outdoor unit may be provided as an environmental sensor. The outdoor unit sensor may be located at any location inside or outside the outdoor unit. For example, the outdoor unit sensor may include a temperature sensor for detecting the air temperature around the outdoor unit, a humidity sensor for detecting the air humidity around the outdoor unit, a refrigerant temperature sensor for detecting the refrigerant temperature of a refrigerant pipe passing through the outdoor unit, a refrigerant pressure sensor for detecting the refrigerant pressure of a refrigerant pipe passing through the outdoor unit, or a combination thereof.

[0057] An outdoor unit of an air conditioner may include an outdoor unit communication unit. The outdoor unit communication unit may be configured to receive a control signal from a control unit of an indoor unit of the air conditioner, which will be described later. The outdoor unit may control the operation of a compressor, an outdoor heat exchanger, an expansion device, a flow switching valve, an accumulator, an outdoor fan, or a combination thereof based on the control signal received through the outdoor unit communication unit. The outdoor unit may transmit a sensing value detected by an outdoor unit sensor to the control unit of the indoor unit through the outdoor unit communication unit.

[0058] The indoor unit of the air conditioner may include a housing, a blower for circulating air into or out of the housing, and an indoor heat exchanger for exchanging heat with air flowing into the interior of the housing.

[0059] The housing may include an intake port through which indoor air may be drawn into the interior of the housing.

[0060] The indoor unit of the air conditioner may include a filter that is provided to filter foreign substances in the air that flows into the housing through the intake port.

[0061] The housing may include an exhaust port. Air flowing within the housing may be discharged to the exterior of the housing through the exhaust port.

[0062] The housing of the indoor unit may be provided with an airflow guide that guides the direction of air discharged through the exhaust port. For example, the airflow guide may include blades positioned above the exhaust port. For example, the airflow guide may include an auxiliary fan for controlling the exhaust airflow. However, the airflow guide is not limited thereto and may be omitted.

[0063] An indoor heat exchanger and a blower may be provided inside the housing of the indoor unit, which are arranged on a path connecting the intake and exhaust ports.

[0064] Blowers may include indoor fans and fan motors. For example, indoor fans may include axial fans, diffusion fans, crossflow fans, and centrifugal fans.

[0065] An indoor heat exchanger may be positioned between the blower and the exhaust, or between the intake and the blower. The indoor heat exchanger may absorb heat from air drawn in through the intake or transfer heat to the air drawn in through the intake. The indoor heat exchanger may include heat exchange tubes through which refrigerant flows, and heat exchange fins in contact with the heat exchange tubes to increase the heat transfer surface area.

[0066] The indoor unit of the air conditioner may include a drain tray positioned below the indoor heat exchanger to collect condensate generated in the indoor heat exchanger. The condensate collected in the drain tray may be drained to the outside through a drain hose. The drain tray may be provided to support the indoor heat exchanger.

[0067] The indoor unit of the air conditioner may include an input interface. The input interface may include any type of user input means, including buttons, switches, a touch screen, and / or a touch pad. The user can directly input setting data (e.g., desired indoor temperature, operating mode settings for cooling / heating / dehumidification / air purification, outlet selection settings, and / or air flow settings) through the input interface.

[0068] The input interface may also be connected to an external input device. For example, the input interface may be electrically connected to a wired remote controller. The wired remote controller may be installed at a specific location in an indoor space (e.g., a portion of a wall). A user may input configuration data regarding the operation of the air conditioner by operating the wired remote controller. Electrical signals corresponding to the configuration data obtained through the wired remote controller may be transmitted to the input interface. In addition, the input interface may include an infrared sensor. A user may remotely input configuration data regarding the operation of the air conditioner using the wireless remote controller. The configuration data input through the wireless remote controller may be transmitted to the input interface as an infrared signal.

[0069] Additionally, the input interface may include a microphone. A user's voice command may be acquired through the microphone. The microphone may convert the user's voice command into an electrical signal and transmit the converted electrical signal to an indoor unit control unit. The indoor unit control unit may control components of the air conditioner to execute a function corresponding to the user's voice command. Setting data acquired through the input interface (e.g., desired indoor temperature, operation mode settings for cooling / heating / dehumidification / air purification, outlet selection settings, and / or air volume settings) may be transmitted to the indoor unit control unit, which will be described later. In one example, the setting data acquired through the input interface may be transmitted externally, i.e., to an outdoor unit or a server, through an indoor unit communication unit, which will be described later.

[0070] The indoor unit of the air conditioner may include a power module. The power module may be connected to an external power source to supply power to the components of the indoor unit.

[0071] An indoor unit of an air conditioner may include an indoor unit sensor. The indoor unit sensor may be an environmental sensor positioned in a space inside or outside the housing. For example, the indoor unit sensor may include one or more temperature sensors and / or humidity sensors positioned in a predetermined space inside or outside the housing of the indoor unit. For example, the indoor unit sensor may include a refrigerant temperature sensor for detecting a refrigerant temperature of a refrigerant pipe passing through the indoor unit. For example, the indoor unit sensor may include respective refrigerant temperature sensors for detecting the inlet, middle, and / or outlet temperatures of the refrigerant pipe passing through the indoor heat exchanger.

[0072] For example, each environmental information detected by an indoor unit sensor can be transmitted to the indoor unit control unit described later or transmitted externally through the indoor unit communication unit described later.

[0073] The indoor unit of the air conditioner may include an indoor unit communication unit. The indoor unit communication unit may include at least one of a short-range communication module and a long-range communication module. The indoor unit communication unit may include at least one antenna for wireless communication with other devices. The outdoor unit may include an outdoor unit communication unit. The outdoor unit communication unit may also include at least one of a short-range communication module and a long-range communication module.

[0074] The short-range wireless communication module may include, but is not limited to, a Bluetooth communication module, a BLE (Bluetooth Low Energy) communication module, a near field communication module, a WLAN (Wi-Fi) communication module, a Zigbee communication module, an infrared (IrDA, infrared Data Association) communication module, a WFD (Wi-Fi Direct) communication module, an UWB (ultrawideband) communication module, an Ant+ communication module, a microwave (uWave) communication module, etc.

[0075] The remote communication module may include a communication module that performs various types of remote communication and may include a mobile communication unit. The mobile communication unit transmits and receives wireless signals with at least one of a base station, an external terminal, and a server on a mobile communication network.

[0076] The indoor unit communication unit can communicate with external devices such as servers, mobile devices, and other home appliances through a nearby access point (AP). The access point (AP) can connect a local area network (LAN) to which the air conditioner or user device is connected to a wide area network (WAN) to which the server is connected. The air conditioner or user device can be connected to the server through the wide area network (WAN). The indoor unit of the air conditioner may include an indoor unit control unit that controls components of the indoor unit, including a blower, etc. The outdoor unit of the air conditioner may include an outdoor unit control unit that controls components of the outdoor unit, including a compressor, etc. The indoor unit control unit can communicate with the outdoor unit control unit through the indoor unit communication unit and the outdoor unit communication unit. The outdoor unit communication unit can transmit control signals generated by the outdoor unit control unit to the indoor unit communication unit, or transmit control signals transmitted from the indoor unit communication unit to the outdoor unit control unit. In other words, the outdoor unit and the indoor unit can communicate bidirectionally. The outdoor unit and the indoor unit can transmit and receive various signals generated during the operation of the air conditioner.

[0077] The outdoor unit control unit can be electrically connected to components of the outdoor unit and can control the operation of each component. For example, the outdoor unit control unit can adjust the frequency of the compressor and control the flow switching valve to change the circulation direction of the refrigerant. The outdoor unit control unit can adjust the rotation speed of the outdoor fan. In addition, the outdoor unit control unit can generate a control signal to adjust the opening degree of the expansion valve. Under the control of the outdoor unit control unit, the refrigerant can circulate along a refrigerant circulation circuit including the compressor, the flow switching valve, the outdoor heat exchanger, the expansion valve, and the indoor heat exchanger.

[0078] The various temperature sensors included in the outdoor and indoor units can transmit electrical signals corresponding to the detected temperatures to the outdoor unit control unit and / or the indoor unit control unit. For example, the humidity sensors included in the outdoor and indoor units can transmit electrical signals corresponding to the detected humidity to the outdoor unit control unit and / or the indoor unit control unit.

The indoor unit control unit can transmit information regarding the received user input to the outdoor unit control unit of the outdoor unit.

[0080] The outdoor unit control unit can control the components of the outdoor unit, including the compressor, based on information regarding user input received from the indoor unit. For example, when a control signal corresponding to a user input for selecting an operation mode, such as cooling operation, heating operation, ventilation operation, defrosting operation, or dehumidification operation, is received from the indoor unit, the outdoor unit control unit can control the components of the outdoor unit so that the air conditioner performs an operation corresponding to the selected operation mode.

[0086] Hereinafter, air conditioners according to various embodiments will be specifically described with reference to the drawings.

[0087] FIG. 1 is a drawing showing the operation of an air conditioner according to one embodiment of the present disclosure.

[0088] According to one embodiment of the present disclosure, an air conditioner (100) performs an air conditioning operation for a target space (140). The air conditioning operation may include, for example, cooling, heating, air purification, dehumidification, or ventilation. The air conditioner (100) may be implemented in the form of an air conditioner, a heater, an air conditioner, an air purifier, or a dehumidifier. In the present disclosure, the case where the air conditioner (100) corresponds to an air conditioner is mainly described. However, this is for convenience of explanation, and the embodiments of the present disclosure are not limited thereto.

[0089] An air conditioner (100) may include an indoor unit (118) and an outdoor unit (116). The indoor unit (118) is placed within a target space (140) and discharges cooled air into the target space (140). The indoor unit (118) may be provided in various forms, such as a standing type, a built-in type, or a window-mounted type. The outdoor unit (116) is placed outside the target space (140). The outdoor unit (116) cools a refrigerant by a compressor (120) and supplies the cooled refrigerant to the indoor unit (118). The refrigerant that has absorbed heat in the indoor unit (118) is then supplied to the outdoor unit (116). The indoor unit (118) and the outdoor unit (116) are connected by a hose, and heat exchange occurs as the refrigerant circulates through the hose.

[0090] The compressor (120) of the outdoor unit (116) absorbs heat from the refrigerant while rotating at a predetermined frequency according to the set temperature. The compressor frequency changes according to the set temperature of the air conditioner (100). At this time, the power consumption of the outdoor unit (116) varies according to the frequency of the compressor. As the compressor frequency of the outdoor unit (116) increases, the power consumption of the air conditioner (100) increases. The compressor (120) of the outdoor unit (116) often accounts for the highest proportion of the power consumption of the air conditioner (100).

[0091] The air conditioner (100) may include a detection sensor (110). The detection sensor (110) detects an object within a target space (140). The air conditioner (100) may detect a movement value of a user (130) within the target space (140) using a sensor detection value of the detection sensor (110). In the present disclosure, the user (130) may correspond to a person or a pet within the target space (140).

[0092] Additionally, the air conditioner (100) may include a light sensor (112). The light sensor (112) detects the light intensity of the target space (140). The air conditioner (100) may use the sensor detection value of the light sensor (112) to identify or obtain the light intensity value of the target space (140). The light intensity value may vary depending on the on / off of the indoor lighting device (150) of the target space (140), the set light intensity, whether other light sources such as sunlight, windows, or lamps are present in the target space (140), etc.

[0093] In addition, the air conditioner (100) may include lighting (114). According to one or more embodiments, the air conditioner (100) may include various types of lighting (114) at various locations on the housing of the air conditioner (100). For example, the air conditioner (100) may be provided with lighting (114) around an air outlet of the air conditioner (100), at a predetermined location on the surface of the housing, etc. In addition, the lighting (114) may be provided in various forms such as line lighting, surface lighting, and circular lamps.

[0094] The target space (140) refers to an indoor space in which an air conditioner (100) can be installed. The target space (140) can correspond to various types of indoor spaces such as a house, office, store, guest room, commercial space, or work space.

[0095] The air conditioner (100) uses the illuminance sensor (112) to determine whether the detected illuminance value is greater than or equal to the illuminance reference value. According to one embodiment of the present disclosure, the air conditioner (100) can control the operation mode of the lighting (114) according to the illuminance value. According to one embodiment of the present disclosure, the air conditioner (100) can control the operation mode of the lighting (114) differently during the day and at night, thereby increasing the usability of the lighting (114) of the air conditioner (100) and increasing user convenience by operating according to the needs of the user (130).

[0096] In addition, the air conditioner (100) uses a detection sensor (110) to determine whether a user (130) is present in the target space (140). According to one embodiment of the present disclosure, the air conditioner (100) can control the operation mode of the lighting (114) differently depending on whether a user (130) is present in the target space (140).

[0097] The air conditioner (100) may control the lighting (114) in a first mode that controls at least one of the lighting intensity or the lighting change pattern of the lighting (114) based on the compressor frequency of the air conditioner (100) when the illuminance value detected by the illuminance sensor (112) in step 160 is higher than the illuminance reference value and a user (130) is detected in the target space (140). The air conditioner (100) may provide information on power consumption through the lighting (114) when the illuminance value is higher than the illuminance reference value and a user (130) is present in the target space (140). According to one embodiment of the present disclosure, the air conditioner (100) may provide information or a notification on power consumption through the lighting (114) by controlling the lighting (114) based on the compressor frequency of the compressor (120) of the outdoor unit (116) that accounts for the highest proportion of power consumption.

[0098] A significant portion of the power consumption of the air conditioner (100) is consumed by the compressor (120) of the outdoor unit (116). For example, when the outdoor unit (116) includes an inverter compressor, more than about 90% of the power consumption is consumed by the compressor (120). The operating frequency of the compressor (120), i.e., the compressor frequency, is usually determined by the difference between the indoor temperature and the set temperature. The compressor (120) operates at a high frequency (Hz) when the difference between the indoor temperature and the set temperature is relatively large, and operates at a low frequency (Hz) when the difference between the indoor temperature and the set temperature is relatively small. The higher the compressor frequency of the compressor (120), the more the power consumption of the air conditioner (100) increases. However, since the compressor (120) is located in the outdoor unit (116), the user (130) of the target space (140), which is an indoor space, cannot know the operating status of the compressor (120). In addition, even if the compressor (120) continues to operate or run at a high frequency due to an opening of a window or other abnormal situation, the user (130) cannot be aware of the abnormal situation of the air conditioner (100). According to one embodiment of the present disclosure, when the illuminance of the target space (140) is equal to or higher than a predetermined illuminance reference value and the user (130) is present, by providing information on the compressor frequency of the compressor (120) using the lighting (114), there is an effect of effectively providing the user (130) with information on power consumption and the operating status of the outdoor unit (116).

[0099] FIG. 2 is a drawing showing the structure of an air conditioner according to one embodiment of the present disclosure.

[0100] According to one embodiment of the present disclosure, an air conditioner (100) includes a detection sensor (110), a light sensor (112), a light (114), a processor (210), an air conditioning module (212), and a memory (214). The block diagram of the air conditioner (100) of FIG. 2 may correspond to the block diagram of an indoor unit. According to one embodiment of the present disclosure, the air conditioner (100) may further include an outdoor unit (116) and a compressor (120).

[0101] The air conditioner (100) can be implemented in various installation forms. For example, the air conditioner (100) can be implemented in a stand form, a wall-mounted form, a system air conditioner built into the ceiling form, or a home multi-air conditioner form.

[0102] The detection sensor (110) can detect an object in a target space (140). The detection sensor (110) may include, for example, a ToF (Time of Flight) sensor, an ultrasonic sensor, an infrared sensor, an optical sensor, a camera, a radar (radio detection and ranging) sensor, or a LiDAR (light detection and ranging) sensor. The detection sensor (110) is arranged to output a signal to the target space (140) and detect a reflected signal. The detection sensor (110) may be arranged in front of the air conditioner (100) toward the target space (140). The detection sensor (110) generates a sensor detection value and transmits it to the processor (210).

[0103] The light sensor (112) is a sensor that measures the brightness of the target space (140). The light sensor (112) may include, for example, a photoresistor, a photodiode, or a phototransistor. The light sensor (112) may be placed in front of the air conditioner (100) toward the target space (140) to detect the illuminance of the target space (140). The light sensor (112) may generate an illuminance value and transmit it to the processor (210).

[0104] The lighting (114) is a device that outputs light to a target space (140). The lighting (114) can be embedded or coupled to the housing of the air conditioner (100) and radiate or emit light around the air conditioner (100). The lighting (114) can include, for example, a light emitting diode (LED) lighting. The lighting (114) can be arranged in various shapes such as a line shape, a surface shape, a dot shape, etc. The lighting (114) can include a plurality of LED lighting. The processor (210) can control the on / off, illuminance, or timing of each of the plurality of LED lighting. The lighting (114) can perform operations such as on / off, illuminance change, dimming, and color change.

[0105] The processor (210) controls the overall operation of the air conditioner (100). The processor (210) may be implemented with one or more processors. The processor (210) may execute instructions or commands stored in the memory (214) to perform a predetermined operation. In addition, the processor (210) controls the operation of components provided in the air conditioner (100). The processor (210) may include a Central Processing Unit (CPU), a microprocessor, etc.

[0106] The processor (210) determines whether there is a moving object using the sensor detection value of the detection sensor (110), and if there is a moving object, determines that there is a person in the target space (140). According to one embodiment of the present disclosure, the processor (210) determines whether the detected object is a person using the sensor detection value. For example, if the detection sensor (110) corresponds to an infrared sensor, the processor (210) determines that there is a person in the target space (140) if an infrared value corresponding to a person is detected. According to one embodiment of the present disclosure, the processor (210) determines whether the detected object has a human shape based on the sensor detection value, and if the detected object corresponds to a human shape, determines that there is a human, i.e., a user (130), in the target space (140).

[0107] The processor (210) can determine that no person exists in the target space (140) if there is no moving object in the target space (140) by using the sensor detection value of the detection sensor (110).

[0108] According to one embodiment of the present disclosure, the detection sensor (110) corresponds to a radar sensor, and the processor (210) can determine whether a detected object is a human shape using a sensor detection value of the radar sensor. The radar sensor outputs a radar signal to a target space (140) and detects a signal reflected from an object in the target space (140) as a sensor detection value. The processor (210) detects an object in the target space (140) using the sensor detection value of the radar sensor. The processor (210) detects an object in the target space (140) at a predetermined frame rate and detects movement of the object. The processor (210) determines that a human exists in the target space (140) if the movement value of the object in the target space (140) is greater than or equal to a reference value. For example, the processor (210) detects an object in the target space (140) at a cycle of 30 frames / sec, and determines that a human exists in the target space (140) if the movement value per second of the object is greater than or equal to a reference value.

[0109] In addition, according to one embodiment of the present disclosure, the processor (210) determines whether the recognized object is a person based on the result of object recognition based on the sensor detection value of the radar sensor. The processor (210) can determine whether the recognized object is a person based on the shape of the recognized object. If the recognized object corresponds to a person and the movement value is greater than or equal to a reference value, the processor (210) determines that a person exists in the target space (140). If the processor (210) determines that the recognized object does not correspond to a person, it determines that a person does not exist in the target space (140). In addition, according to one embodiment of the present disclosure, the processor (210) can determine that a person exists in the target space (140) even when the recognized object corresponds to a pet. Therefore, the processor (210) can determine that a person exists in the target space (140) if the detected object corresponds to a person or a pet and the movement value is greater than or equal to a reference value.

[0110] The air conditioning module (212) performs air conditioning operations. The air conditioning module (212) controls cooling, cooling intensity, heating, heating intensity, air volume, etc. based on a control signal or drive signal input from the processor (210). The air conditioning module (212) may include a heat exchanger, a motor, an inverter, a fan, a filter, etc. The air conditioning module (212) is provided with a heat exchanger and may perform heat exchange between the refrigerant and indoor air by utilizing a phase change (e.g., expansion or compression) of the refrigerant in the heat exchanger. For example, while the refrigerant expands in the heat exchanger, the refrigerant may absorb heat from the indoor air, and the indoor air may be cooled. While the refrigerant is compressed in the heat exchanger, the refrigerant may release heat to the indoor air, and the indoor air may be heated.

[0111] In addition, the air conditioning module (212) may include an outdoor unit (116), and the outdoor unit (116) may include a compressor (120). The processor (210) may set the compressor frequency of the compressor (120) of the outdoor unit (116) based on the difference between the indoor temperature and the set temperature. In addition, the processor (210) may monitor the status of the outdoor unit (116) and the compressor (120).

[0112] The memory (214) stores various information, data, commands, programs, etc. required for the operation of the air conditioner (100). The memory (214) may include at least one of volatile memory and non-volatile memory, or a combination thereof. The memory (214) may include at least one type of storage medium among a flash memory type, a hard disk type, a multimedia card micro type, a card type memory (e.g., SD or XD memory, etc.), a RAM (Random Access Memory), a SRAM (Static Random Access Memory), a ROM (Read-Only Memory), an EEPROM (Electrically Erasable Programmable Read-Only Memory), a PROM (Programmable Read-Only Memory), a magnetic memory, a magnetic disk, and an optical disk. In addition, the memory (214) may correspond to a web storage or cloud server that performs a storage function on the Internet.

[0113] The processor (210) obtains an illuminance value from the illuminance sensor (112). According to one embodiment of the present disclosure, the processor (210) may obtain the illuminance value by performing a predetermined process on the sensor detection value from the illuminance sensor (112). The processor (210) determines whether the illuminance value is equal to or greater than a first illuminance reference value. The first illuminance reference value may be, for example, substantially 6 lux.

[0114] In addition, the processor (210) controls the illuminance or illuminance change pattern of the lighting (114) based on the compressor frequency of the air conditioning module (212) when the illuminance value is greater than or equal to the first illuminance reference value and a user (130) is present in the target space (140). Illuminance refers to the brightness or illuminance intensity of the lighting (114). The processor (210) can control the illuminance of the lighting (114) through a control signal that controls the brightness of the lighting (114). The illuminance change pattern refers to a pattern in which the illuminance of the lighting (114) changes. The change in illuminance can be defined by a combination of an illuminance rising pattern, a illuminance falling pattern, or a holding pattern. The illuminance change pattern can have a predetermined cycle. For example, the illuminance change pattern can be defined in the form of a sine function or a cosine function. The illuminance change pattern can be defined by a maximum illuminance, a minimum illuminance, and a cycle. For example, the illuminance change pattern may have the form of a sine function and may be defined by a peak illuminance, a minimum illuminance, and a period.

[0115] Additionally, for example, the light change pattern may include a color change pattern of the light (114).

[0116] According to one embodiment of the present disclosure, the processor (210) can define an illuminance value, i.e., an illumination intensity, of the light (114) based on the compressor frequency. For example, the processor (210) can increase the illumination intensity of the light (114) as the compressor frequency increases.

[0117] Additionally, according to one embodiment of the present disclosure, the processor (210) may define parameters of the illuminance change pattern based on the compressor frequency. The parameters of the illuminance change pattern may include at least one of a period, a maximum illuminance, or a minimum illuminance. For example, the processor (210) may adjust the period of the illuminance change pattern based on the compressor frequency. Specifically, the processor (210) may decrease the period of the illuminance change pattern as the compressor frequency increases.

[0118] Additionally, for example, the processor (210) can change the color of the light (114) based on the compressor frequency. The light (114) includes a plurality of light elements of different colors, and the light color can be adjusted by selectively turning on the plurality of light elements.

[0119] Illumination patterns can be defined by cycles, peak intensity, minimum intensity, or various combinations of light colors.

[0120] According to one embodiment of the present disclosure, the processor (210) may not operate in the first mode for controlling the lighting (114) according to the compressor frequency when the illuminance value is less than the first illuminance reference value or when a user (130) is not detected in the target space (140).

[0121] FIG. 3 is a flowchart illustrating an air conditioner control method according to one embodiment of the present disclosure.

[0122] According to one embodiment of the present disclosure, an air conditioner control method can be performed by an air conditioner (100). The present disclosure will focus on an embodiment in which an air conditioner (100) performs the air conditioner control method.

[0123] Referring to FIG. 3, in step S302, the air conditioner (100) detects an illuminance value using the illuminance sensor (112). The air conditioner (100) can detect an illuminance value of a target space (140) using the illuminance sensor (112).

[0124] Next, in step S304, the air conditioner (100) determines whether the illuminance value detected by the illuminance sensor (112) is equal to or greater than a first illuminance reference value. The first illuminance reference value may be determined, for example, in a range of about 4 to 8 lux. For example, the first illuminance reference value may substantially correspond to 6 lux.

[0125] If the illuminance value detected by the illuminance sensor (112) is equal to or greater than the first illuminance reference value, the air conditioner (100) detects a person, i.e., a user (130), in the target space (140) using the detection sensor (110) in step S306. The air conditioner (100) can detect the user (130) in the target space (140) using the sensor detection value of the detection sensor (110).

[0126] Next, the air conditioner (100) determines in step S308 whether a user (130) is detected in the target space (140).

[0127] If a person is detected, the air conditioner (100) controls the illuminance or illuminance change pattern of the lighting (114) based on the compressor frequency of the outdoor unit (116) in step S310. If the illuminance value of the target space (140) is equal to or greater than the first illuminance reference value and a user (130) is detected in the target space (140), the air conditioner (100) can control the air conditioning module (212) in the first mode. In the first mode, the air conditioner (100) controls the illuminance or illuminance change pattern of the lighting (114) based on the compressor frequency of the outdoor unit (116).

[0128] According to one embodiment of the present disclosure, the air conditioner (100) can define the illuminance value, i.e., the illuminance intensity, of the light (114) based on the compressor frequency. For example, the processor (210) can increase the illuminance of the light (114) as the compressor frequency increases. Furthermore, according to one embodiment of the present disclosure, the air conditioner (100) can define the parameters of the illuminance change pattern based on the compressor frequency. The parameters of the illuminance change pattern can include at least one of a period, a maximum illuminance, or a minimum illuminance. For example, the processor (210) can adjust the period of the illuminance change pattern based on the compressor frequency. Specifically, the processor (210) can decrease the period of the illuminance change pattern as the compressor frequency increases.

[0129] According to one embodiment of the present disclosure, the air conditioner (100) can provide information about the compressor frequency through the light (114) for a predetermined period of time in the first mode, and turn off the light (114) after the predetermined period of time. For example, the air conditioner (100) can control the illumination intensity or the illumination change pattern of the light (114) according to the compressor frequency for 30 seconds in the first mode, and turn off the light (114) substantially after 30 seconds.

[0130] Additionally, according to one embodiment of the present disclosure, the air conditioner (100) may provide information about the compressor frequency through the light (114) for a predetermined period of time at predetermined intervals in the first mode and then turn off the light (114). For example, the air conditioner (100) may provide information about the compressor frequency through the light (114) at substantially 10-minute intervals. Additionally, the air conditioner (100) may turn on the light (114) with an illumination or illumination change pattern corresponding to the compressor frequency for a substantially 30-second period out of the substantially 10-minute period, and turn off the light (114) at a time interval other than the substantially 30-second period out of the substantially 10-minute period.

[0131] In addition, according to one embodiment of the present disclosure, the air conditioner (100) may provide information about the compressor frequency through the lighting (114) for a predetermined period of time when the compressor frequency changes beyond a predetermined range in the first mode. For example, the air conditioner (100) may provide information about the compressor frequency through the lighting (114) for substantially 30 seconds when the compressor frequency increases substantially 1.5 times or more in substantially 30 seconds in the first mode. In addition, for example, the air conditioner (100) may define a predetermined number of ranges for the compressor frequency, and may provide information about the compressor frequency through the lighting (114) when the compressor frequency changes to another range among the predetermined number of ranges.

[0132] Additionally, according to one embodiment of the present disclosure, the air conditioner (100) may provide information about the compressor frequency through the light (114) when the compressor frequency exceeds a reference value in the first mode. For example, the air conditioner (100) may provide information about the compressor frequency through the light (114) when the compressor frequency exceeds a value corresponding to substantially 50% of the entire range of compressor frequencies.

[0133] According to one embodiment of the present disclosure, the execution order of steps S302 and S306 is not limited to the order illustrated in FIG. 3, and may be repeatedly performed during the operation of the air conditioner (100). For example, steps S302 and S306 may be constantly or periodically performed during the operation of the air conditioner (100). Furthermore, according to one embodiment of the present disclosure, it is also possible for step S306 to be performed first and step S302 to be performed later. Furthermore, according to one embodiment of the present disclosure, it is also possible for steps S302 and S306 to be performed in parallel.

[0134] Additionally, according to one embodiment of the present disclosure, the order of performing steps S304 and S308 is not limited to the order illustrated in FIG. 3. According to one embodiment of the present disclosure, it is also possible for step S308 to be performed first and step S304 to be performed later. Furthermore, according to one embodiment of the present disclosure, it is also possible for steps S304 and S308 to be performed in parallel.

[0135] FIG. 4 is a flowchart illustrating an air conditioner control method according to one embodiment of the present disclosure.

[0136] According to one embodiment of the present disclosure, the air conditioner (100) can operate in a first mode that controls the lighting (114) based on the compressor frequency, and a second mode that turns on the lighting (114) with a certain intensity of illumination. When the illuminance value is equal to or greater than a first illuminance reference value, the air conditioner (100) determines that it is a time when a user (130) is active, and when a user (130) is detected, the air conditioner (100) can operate in the first mode that provides information on the operation of the compressor (120) of the outdoor unit (116) through the lighting (114). In addition, when the illuminance value is equal to or less than a second illuminance reference value, the air conditioner (100) determines that it is nighttime, and when a user (130) is detected, the air conditioner (100) can operate in the second mode and provide indoor lighting through the lighting (114) to assist the activity of the user (130).

[0137] In order to avoid duplication of explanation in Fig. 4, explanations that overlap with Fig. 3 are omitted, and explanations are focused on differences from Fig. 3.

[0138] Referring to FIG. 4, the air conditioner (100) detects the illuminance value of the target space (140) using the illuminance sensor (112) in step S302.

[0139] Next, the air conditioner (100) determines whether the illuminance value detected by the illuminance sensor (112) in step S304 is equal to or greater than the first illuminance reference value. If the illuminance value detected by the illuminance sensor (112) in step S304 is equal to or greater than the first illuminance reference value, the air conditioner (100) detects a person, i.e., a user (130), in the target space (140) using the detection sensor (110) in step S306. If the air conditioner (100) determines that a user (130) is detected in the target space (140) in step S308, the air conditioner (100) operates in a first mode that controls at least one of the illuminance or illuminance change pattern of the lighting (114) based on the compressor frequency of the outdoor unit (116) in step S310.

[0140] Next, the air conditioner (100) operates in the first mode and determines whether a user (130) is detected from the target space (140) in step S414. If the user (130) is not detected from the target space (140), the air conditioner (100) controls the lighting (114) in the first mode for a reference time in step S416 and then turns off the lighting (114).

[0141] If the air conditioner (100) determines in step S304 that the illuminance value detected by the illuminance sensor (112) is less than the first illuminance reference value, it determines in step S402 whether the illuminance value detected by the illuminance sensor (112) is less than or equal to the second illuminance reference value. The second illuminance reference value is a value that is less than or equal to the first illuminance reference value and greater than 0. The second illuminance reference value can be determined, for example, within the range of 2 to 4 lux. The second illuminance reference value can be set, for example, to 3 lux.

[0142] If the illuminance value detected by the illuminance sensor (112) in step S402 is lower than or equal to the second illuminance reference value, the air conditioner (100) detects a user (130) in the target space (140) using the sensor detection value of the detection sensor (110) in step S404. The air conditioner (100) determines whether a user (130) has been detected in the target space (140) in step S406.

[0143] If a user (130) is detected in the target space (140) in step S406, the air conditioner (100) operates in a second mode in step S408, turning on the lighting (114) of the air conditioner (100) at a first level of illumination. The first level of illumination may correspond to, for example, an illumination in the range of 10 to 100 lux. The first level of illumination may correspond to night lighting or sleep lighting that assists the user (130) at night. The air conditioner (100) can provide night lighting to the user (130) by constantly controlling the illumination of the lighting (114) to the first level of illumination.

[0144] Next, in step S410, the air conditioner (100) determines whether a user (130) is detected from the target space (140) while the lighting (114) is turned on in the second mode. If the user (130) is detected from the target space (140) in the second mode, the air conditioner (100) proceeds to step S408 and controls the lighting (114) to continue operating in the second mode.

[0145] In the second mode, when a user (130) is not detected from the target space (140), the air conditioner (100) maintains the lighting (114) at the first level of illumination for a reference time in step S412, and then turns off the lighting (114).

[0146] The air conditioner (100) can repeatedly perform steps S302, S306, and S404 to determine whether to operate in the first mode or the second mode. In addition, the order of steps S302, S306, and S404 is not limited to the order shown in FIG. 4, and each step can be performed repeatedly, performed in a different order than FIG. 4, or performed in parallel.

[0147] Additionally, according to one embodiment of the present disclosure, the order of performing steps S304 and S308 is not limited to the order illustrated in FIG. 4. According to one embodiment of the present disclosure, it is also possible for step S308 to be performed first and step S304 to be performed later. Furthermore, according to one embodiment of the present disclosure, it is also possible for steps S304 and S308 to be performed in parallel.

[0148] Additionally, according to one embodiment of the present disclosure, the order of performing steps S402 and S406 is not limited to the order illustrated in FIG. 4. According to one embodiment of the present disclosure, it is also possible for step S406 to be performed first and step S402 to be performed later. Furthermore, according to one embodiment of the present disclosure, it is also possible for steps S402 and S406 to be performed in parallel.

[0149] FIG. 5 is a diagram showing the operation of the first mode and the second mode according to one embodiment of the present disclosure.

[0150] According to one embodiment of the present disclosure, the air conditioner (100) operates in the first mode when the illuminance value detected by the illuminance sensor (112) is equal to or greater than the first illuminance reference value and a user (130) is detected from the target space (140). For example, when the indoor lighting device (150) of the target space (140) is turned on or natural light is incident on the target space (140) during the day, the illuminance value detected by the illuminance sensor (112) may be equal to or greater than the first illuminance reference value.

[0151] In addition, according to one embodiment of the present disclosure, the air conditioner (100) operates in the second mode when the illuminance value detected by the illuminance sensor (112) is lower than or equal to the second illuminance reference value and a user (130) is detected from the target space (140). For example, when the indoor lighting device (150) of the target space (140) is turned off and natural light does not enter above a certain illuminance, the illuminance value detected by the illuminance sensor (112) may be lower than or equal to the second illuminance reference value.

[0152] In the first mode, the air conditioner (100) can adjust the illuminance or illuminance change pattern of the lighting (114) based on the compressor frequency of the compressor (120). The illuminance change pattern can include at least one of a dimming pattern, a blinking pattern, a lighting direction change pattern, or a lighting width change pattern. The dimming pattern refers to a pattern in which the illuminance gradually darkens and gradually brightens. The blinking pattern refers to a pattern in which the lighting (114) is repeatedly turned on and off. The lighting direction change pattern refers to a pattern in which the direction of the lighting (114) moves over time. For example, when the lighting (114) includes a plurality of light-emitting elements, the air conditioner (100) can move the direction of the lighting (114) by changing the section in which the light-emitting elements are turned on over time. The lighting width change pattern refers to a pattern in which the width of the section in which the lighting (114) is turned on changes over time.

[0153] According to one embodiment of the present disclosure, in the first mode, the air conditioner (100) can control the illuminance of the light (114) over time, such as pattern 510. For example, pattern 510 may correspond to a pattern of a sine function and have a period of T1. In addition, pattern 510 may have a minimum level Lmin and a maximum level Lmax. According to one embodiment of the present disclosure, the air conditioner (100) can adjust at least one of the period, the minimum level, or the maximum level of the illuminance change pattern based on the compressor frequency. For example, the air conditioner (100) can decrease the period T1 as the compressor frequency increases, and can increase the period T1 as the compressor frequency decreases. In addition, for example, the air conditioner (100) can increase at least one of the minimum level Lmin or the maximum level Lmax as the compressor frequency increases, and can decrease at least one of the minimum level Lmin or the maximum level Lmax as the compressor frequency decreases.

[0154] According to one embodiment of the present disclosure, in the first mode, the air conditioner (100) can adjust the illuminance level of the lighting (114) based on the illuminance value detected by the illuminance sensor (112). The air conditioner (100) can increase the illuminance level of the lighting (114) as the illuminance value detected by the illuminance sensor (112) is higher, and can decrease the illuminance level of the lighting (114) as the illuminance value detected by the illuminance sensor (112) is lower. For example, the air conditioner (100) can adjust at least one of the minimum level Lmin or the maximum level Lmax based on the illuminance value detected by the illuminance sensor (112) in pattern 510. According to one embodiment of the present disclosure, by adjusting at least one of the minimum level Lmin or the maximum level Lmax based on the illuminance value detected by the illuminance sensor (112), there is an effect of further improving the visibility of information about the compressor frequency through the lighting (114) in the first mode.

[0155] According to one embodiment of the present disclosure, in the second mode, the air conditioner (100) turns on the light (114) at a first level of illuminance. According to one embodiment of the present disclosure, the first level may correspond to the lowest illuminance that can be set in the light (114). In the second mode, the air conditioner (100) maintains the illuminance of the light (114) at a constant illuminance of the first level. In the second mode, the light (114) may function as a night light or an indoor light.

[0156] FIG. 6 is a diagram illustrating the operation of an air conditioner in a first mode according to one embodiment of the present disclosure.

[0157] According to one embodiment of the present disclosure, the air conditioner (100) can dim and control the illuminance of the light (114) in the form of a sine function in the first mode. While the air conditioner (100) operates in the first mode, in step 610, the dimming cycle can be adjusted according to the compressor frequency.

[0158] According to one embodiment of the present disclosure, the air conditioner (100) can control the lighting (114) according to the compressor frequency according to the criterion 612. The air conditioner (100) can divide the entire range of the compressor frequency into a predetermined number of ranges according to the criterion 612, and control the intensity and dimming cycle of the lighting (114) according to the range to which the compressor frequency belongs. For example, the criterion 612 can divide the range of the compressor frequency into three ranges of substantially 0% to 33% of the entire range, substantially 34% to 66% of the entire range, and substantially 67% to 100%. It should be understood that other ranges may be used and are not limited to the exemplary ranges described. The criterion 612 can define the lighting intensity and dimming cycle as a weak level in the compressor frequency range of 0% to 33%. Additionally, the criterion 612 can define the lighting intensity and dimming cycle as a medium level in the compressor frequency range of 34% to 66%. In addition, Standard 612 can define the lighting intensity and dimming cycle as strong levels in the compressor frequency range of 67% to 100%. For example, the lighting intensity at a weak level, the lighting intensity at a medium level, and the lighting intensity at a strong level can each be defined as a predetermined illuminance value. The illuminance value can be defined as a higher illuminance value as the lighting intensity at a weak level, the lighting intensity at a medium level, and the lighting intensity at a strong level increases. In addition, for example, the dimming cycle at a weak level, the dimming cycle at a medium level, and the dimming cycle at a strong level can each be defined as a predetermined cycle value. The dimming cycle at a weak level, the dimming cycle at a medium level, and the dimming cycle at a strong level can each be defined as a shorter cycle value as the lighting intensity at a strong level increases.

[0159] In Fig. 6, the illuminance change patterns (620, 630) for two compressor frequencies, low frequency and high frequency, are described as examples. When the compressor frequency corresponds to a low frequency, which is a relatively low frequency, the air conditioner (100) can control the intensity of the lighting (114), i.e., the illuminance, with the pattern 620. The illuminance change cycle in the pattern 620 corresponds to T1. In addition, when the compressor frequency corresponds to a high frequency, which is a relatively high frequency, the air conditioner (100) can control the illuminance of the lighting (114) with the pattern 630. The illuminance change cycle in the pattern 630 corresponds to T2. T1 may be a longer cycle than T2. ​​According to one embodiment of the present disclosure, by adjusting the dimming cycle of the lighting (114) according to the compressor frequency as illustrated in Fig. 6, information on the compressor frequency can be provided to the user (130) through the lighting (114).

[0204] Referring to FIGS. 13 and 14, an embodiment of learning power consumption according to environmental information in an air conditioner (100) and providing information on abnormal operation is described.

[0205] According to one embodiment of the present disclosure, the processor (210) can collect environmental information of the target space (140) and power consumption information of the air conditioner (100) corresponding to each environmental information.

[0207] The air conditioner (100) may include a predetermined power module. The power module receives power from an external power source, converts current and voltage, and supplies power to each component of the air conditioner (100). The processor (210) may collect information on power consumption from the power module.

[0208] As illustrated in FIG. 14, the processor (210) can collect environmental information and power consumption of the air conditioner (100) and learn power consumption corresponding to each environmental information. The processor (210) can store the collected environmental information and power consumption in the memory (214). The processor (210) can collect a predetermined number of pieces of power consumption information under the same environmental conditions and learn power consumption corresponding to each environmental condition. For example, the processor (210) can accumulate substantially 20 or more pieces of power consumption information under each environmental condition and, using the accumulated data, define power consumption information under each environmental condition as shown in the first table (1410) of FIG. 14. The same environmental condition means a condition in which each parameter included in the environmental information, i.e., indoor temperature, indoor humidity, outdoor temperature, and outdoor humidity, is the same. The processor (210) can fill in the power consumption value under each environmental condition in the first table (1410) by learning the collected data. The processor (210) can store the first table (1410) in the memory (214) and update the first table (1410) while performing learning.

[0209] According to one embodiment of the present disclosure, power consumption learning for each environmental condition can be performed by a server. The server can collect environmental information and power consumption information from the air conditioner (100) and learn power consumption according to each environmental condition. The server can provide the learned power consumption information according to the environmental condition to the air conditioner (100).

[0210] Once the learning of power consumption according to environmental conditions is completed, the air conditioner (100) uses the learned data to determine whether power consumption is normal under the current environmental conditions. The processor (210) can determine whether power consumption is normal based on the difference between the power consumption under the current environmental conditions and the learned power consumption. For example, the processor (210) can determine that power consumption is abnormal if the difference between the current power consumption and the learned power consumption is substantially 50% or more of the learned power consumption. The processor (210) can determine that power consumption is normal if the difference between the current power consumption and the learned power consumption is substantially less than 50% of the learned power consumption. The criteria for determining that power consumption is abnormal may be determined in various ways depending on the embodiment.

[0211] According to one embodiment of the present disclosure, if the air conditioner (100) determines that power consumption is abnormal, it provides a notification to the user. If the processor (210) determines that power consumption is abnormal, it can provide an abnormal operation notification indicating that power consumption is abnormal to an external device. The processor (210) can transmit the abnormal operation notification to a server via the communication module (1330). The server can then provide the abnormal operation notification to the external device, thereby outputting the abnormal operation notification to the user via the external device. Furthermore, according to one embodiment of the present disclosure, the processor (210) can output the abnormal operation notification via an output interface or a remote controller provided in the air conditioner (100). According to one embodiment of the present disclosure, the processor (210) can output an abnormal operation notification by outputting a light signal of a predefined pattern via the light (114).

[0214] The server (1520) can manage user account information and information about the air conditioner (100) connected to the user account. For example, a user can access the server (1520) via an external device (1510) and create a user account. The user account can be identified by an ID and password set by the user.

[0242] Fig. 17 is a flowchart illustrating an air conditioner control method according to one embodiment of the present disclosure.

[0243] Referring to FIG. 17, the air conditioner (100) collects environmental information of the target space (140) and power consumption of the air conditioner (100) in step S1702. The environmental information is information indicating the environmental conditions of the target space (140). The environmental information may include, for example, at least one of indoor temperature, indoor humidity, outdoor temperature, or outdoor humidity. According to one embodiment of the present disclosure, the air conditioner (100) may obtain indoor temperature information using a temperature sensor (1310) of an indoor unit, and may obtain indoor humidity information using a humidity sensor (1320) of the indoor unit. In addition, according to one embodiment of the present disclosure, the air conditioner (100) may obtain outdoor temperature information using a temperature sensor of an outdoor unit, and may obtain outdoor humidity information using a humidity sensor of an outdoor unit.

[0244] According to one embodiment of the present disclosure, the air conditioner (100) can collect environmental information and power consumption in step S1702 after being installed in the target space (140) of the air conditioner (100). The air conditioner (100) can obtain identification information or location information about the target space (140) and collect environmental information and power consumption corresponding to the identification information or location information.

[0245] According to one embodiment of the present disclosure, the air conditioner (100) can obtain environmental information using an external temperature sensor or humidity sensor. The air conditioner (100) can receive indoor temperature information, indoor humidity information, outdoor temperature information, or outdoor humidity information from an external temperature sensor or humidity sensor through a communication module (1330). For example, the air conditioner (100) can obtain indoor temperature information using a temperature sensor placed in a target space (140), or can obtain indoor humidity information using a humidity sensor placed in the target space (140). In addition, for example, the air conditioner (100) can obtain outdoor temperature information using a temperature sensor placed outdoors, or can obtain outdoor humidity information using a humidity sensor placed outdoors.

[0246] According to one embodiment of the present disclosure, the air conditioner (100) can collect environmental information by using various combinations of a temperature sensor and a humidity sensor provided in an indoor or outdoor unit of the air conditioner (100) and a temperature sensor and a humidity sensor provided in an external device.

[0247] Additionally, the air conditioner (100) collects power consumption information based on environmental information. The air conditioner (100) can obtain information on power consumption from the power module of the air conditioner (100).

[0248] Next, in step S1704, the air conditioner (100) learns the power consumption of the air conditioner (100) according to the environmental information. The air conditioner (100) learns the power consumption in each environmental condition defined by the environmental information. The air conditioner (100) accumulates a predetermined number or more of power consumption information in each environmental condition. The air conditioner (100) learns the power consumption in each environmental condition using the accumulated power consumption information in each environmental condition. The air conditioner (100) can learn the power consumption in each environmental condition using various types of learning algorithms. In addition, according to one embodiment of the present disclosure, the air conditioner (100) can learn the power consumption in each environmental condition by calculating an average value of learning data of power consumption in each environmental condition.

[0249] According to one embodiment of the present disclosure, the air conditioner (100) can learn power consumption according to environmental conditions after initial installation. When learning of power consumption for a given environmental condition is completed, the air conditioner (100) can use the learned power consumption value in step S1706. The air conditioner (100) may not perform step S1706 for environmental conditions for which learning of power consumption has not been completed.

[0250] Next, in step S1706, the air conditioner (100) determines whether the current power consumption exceeds the learned power consumption under the current environmental conditions by a reference range. The air conditioner (100) can obtain current environmental information and obtain a learned power consumption value under environmental conditions corresponding to the current environmental information. In addition, the air conditioner (100) can obtain the current power consumption value. The air conditioner (100) determines whether the current power consumption value exceeds the learned power consumption value corresponding to the current environmental conditions by a reference range. The reference range is, for example, a value corresponding to a predetermined percentage of the learned power consumption. For example, the reference range is a value corresponding to 50% of the learned power consumption. The air conditioner (100) can determine whether the current power consumption exceeds the learned power consumption value for the current environmental conditions by 50% or more.

[0251] If the air conditioner (100) determines in step S1706 that the current power consumption exceeds the learned power consumption by a standard range, the air conditioner (100) determines in step S1708 that the air conditioner (100) is operating abnormally.

[0252] If the air conditioner (100) is determined to be operating abnormally, it provides an abnormal operation notification in step S1710. For example, the air conditioner (100) may provide an abnormal operation notification through an external device (1510). Additionally, for example, the air conditioner (100) may provide an abnormal operation notification through an output interface of the air conditioner (100).

[0253] FIG. 18 is a diagram illustrating the operation of an air conditioner when a new user is detected in a target space, according to one embodiment of the present disclosure.

For example, the air conditioner (100) can output welcome lighting corresponding to the entry of the user (130).

[0255] The air conditioner (100) can detect a new user (130) entering the target space (140) when the illuminance value of the target space (140) is equal to or greater than the first illuminance reference value in step S1802. When the illuminance value is equal to or greater than the first illuminance reference value, and the air conditioner (100) determines that the user (130) is not detected in the target space (140) and is therefore absent, the air conditioner keeps the lighting (114) in an off state.

[0256] In this way, when the illuminance value is higher than the first illuminance reference value and a new user (130) is detected while the light (114) is turned on, the air conditioner (100) outputs a light signal of a first pattern through the light (114) in step S1804. The light signal of the first pattern is a light signal that reacts to the user (130) who has entered the room. The first pattern may correspond to a dimming pattern, a blinking pattern, a reciprocating pattern, or a rotation pattern.

[0257] The air conditioner (100) can operate in a first mode that controls the illumination intensity or illumination change pattern of the illumination (114) according to the compressor frequency in step S1806 after outputting a light signal of a first pattern through the illumination (114) for a reference time.

[0258] A device-readable storage medium may be provided in the form of a non-transitory storage medium. Here, the term "non-transitory storage medium" simply means a tangible device that does not contain signals (e.g., electromagnetic waves). This term does not distinguish between cases where data is permanently stored in the storage medium and cases where data is temporarily stored. For example, a "non-transitory storage medium" may include a buffer in which data is temporarily stored.
