Description

Technology Field

[0001] The present invention relates to a method for controlling a cooling unit to minimize indoor temperature deviation, which is performed by a control system connected to a cooling unit, wherein the method comprises receiving base information including the operating cycle of the cooling unit, the operating time of the cooling unit, and a target indoor temperature input from a user terminal, correcting the operating time based on environmental information related to the indoor space where cooling is performed for each operating cycle and the base information, and controlling the cooling mode to operate by distinguishing between the corrected operating time and the idle time for each operating cycle. Background Technology

[0003] Cooling control technology has evolved to simultaneously satisfy user convenience and energy efficiency. Among these, timer cooling is a method of operating the air conditioner intermittently according to the operation cycle and timer cooling time entered by the user; because it has a simple structure and can be expected to achieve a certain level of energy savings, it is widely applied in residential and small commercial cooling systems. For example, if the user sets the operation cycle to 1 hour and the timer cooling time to 20 minutes, the air conditioner operates repeatedly, running for only 20 minutes every hour and stopping for the remaining 40 minutes. The duty ratio is determined according to the set operation cycle and timer cooling time to control the operation cycle of the air conditioner.

[0004] Meanwhile, timer cooling fails to reflect environmental information such as changes in indoor temperature, outdoor temperature, and solar radiation, and operates in the same pattern according to a fixed cycle and time. Consequently, the indoor temperature may repeatedly rise or fall excessively depending on the actual cooling situation, leading to a situation where cooling comfort is reduced and energy efficiency decreases.

[0005] Conventional air conditioner control systems include an artificial intelligence control system for air conditioner control, such as Korean Registered Patent No. 10-2389215. The aforementioned artificial intelligence control system for air conditioner control discloses a configuration that controls wind speed, air volume, temperature and humidity, and ventilation to maintain indoor comfort based on the user's activity level and clothing condition. Meanwhile, the aforementioned air conditioner control system focuses only on real-time control based on the user's physical condition or clothing status, and does not include a function to flexibly adjust cooling operation conditions by sufficiently considering changes in the indoor environment or external conditions.

[0006] Therefore, there is a need to develop air conditioner control technology that can flexibly set operating conditions according to various environmental factors, reduce indoor temperature fluctuations, and increase energy efficiency. Prior art literature

[0035] FIG. 1 schematically illustrates the steps of a method for controlling a cooling unit that variably controls the duty ratio according to an environment according to an embodiment of the present invention, and FIG. 2 schematically illustrates a control system (2000) that performs a method for controlling a cooling unit that variably controls the duty ratio according to an environment according to an embodiment of the present invention.

[0037] As illustrated in FIGS. 1 and 2, a control system (2000) that performs a method for controlling a cooling device to minimize indoor temperature deviation, comprising one or more processors and one or more memories, comprises: a cooling setting receiving unit (2100) that receives base information including the operating cycle of a cooling device (1000), the operating time of a cooling device (1000), and a target indoor temperature input from a user terminal (5000); and an operating time correction unit (2200) that corrects the operating time based on environmental information related to the indoor space where cooling is performed according to the operating cycle and the base information. The control system (2000) includes a duty cycle cooling control unit (2300) that controls the operation of the air conditioner (1000) in a first mode to perform indoor cooling so that the indoor temperature reaches a target indoor temperature during an operation time corrected for each operation cycle, and in a second mode to perform indoor cooling so that the indoor temperature maintains the target indoor temperature during an idle time excluding the operation time in the operation cycle, or controls the operation of the air conditioner (1000) to stop. The environmental information includes the current indoor temperature, and the operation time correction unit (2200) corrects the operation time in a direction that increases the operation time of the corresponding operation cycle when the current indoor temperature is higher than the target indoor temperature, and corrects the operation time in a direction that decreases the operation time of the corresponding operation cycle when the current indoor temperature is lower than the target indoor temperature.

[0039] Specifically, the control system (2000) is connected to the air conditioner (1000) and can control the operation of the air conditioner (1000).

[0040] In addition, the control system (2000) can communicate with an external service server (3000) and an external server (6000) through a server network (4000).

[0041] The above service server (3000) is linked with a user terminal (5000) and transmits base information, including the operation cycle of the air conditioner (1000), the operation time of the air conditioner (1000), and the target indoor temperature entered by the user, to the control system (2000), thereby enabling the control system (2000) to control the air conditioner (1000) according to the settings entered by the user.

[0043] The above control system (2000) includes a cooling setting receiving unit (2100), an operation time correction unit (2200), and a duty cycle cooling control unit (2300), and the cooling setting receiving unit (2100) can perform a cooling setting receiving step (S100) of receiving base information including the operation cycle of the air conditioner (1000), the operation time of the air conditioner (1000), and the target indoor temperature input through the user terminal (5000).

[0045] The above-mentioned operation time correction unit (2200) can perform an operation time correction step (S200) that corrects the operation time of the air conditioner (1000) based on the indoor environment where cooling is performed according to the operation cycle, related environmental information, and the above-mentioned base information.

[0046] The above environmental information may include the current indoor temperature, and the operation time correction unit (2200) can achieve the effect of minimizing the deviation of the indoor temperature by comparing the current indoor temperature with the target indoor temperature and correcting the operation time in a direction that increases or decreases it.

[0047] The specific details regarding the execution process of the above-mentioned operation time correction step (S200) will be described in more detail later in the explanation of Fig. 6.

[0049] The above duty cycle cooling control unit (2300) can perform a duty cycle cooling control step (S300) that controls the operation of the air conditioner (1000) in a first mode during the operation time corrected for each operation cycle, and controls the operation of the air conditioner (1000) in a second mode or stops the operation of the air conditioner (1000) during the idle time excluding the operation time in the operation cycle.

[0050] The above first mode may correspond to an operating mode in which the air conditioner (1000) is operated with normal output so that the indoor temperature can reach the target indoor temperature.

[0051] Meanwhile, the second mode is an auxiliary operation mode for maintaining the temperature of the indoor space cooled through the first mode, and can perform auxiliary cooling operation by operating the air conditioner (1000) at a low output so as to prevent a rapid rise in indoor temperature and minimize temperature deviation.

[0052] In addition, when the above-mentioned air conditioner (1000) operates in an inverter mode, by continuing low-output operation in the second mode during the above-mentioned idle time, it is possible to reduce power consumption generated during the repetitive starting process of the outdoor unit and thereby achieve the effect of improving energy efficiency.

[0053] In one embodiment of the present invention, by distinguishing and controlling the operating mode of the air conditioner (1000) based on the operating time and idle time, unnecessary operation of the air conditioner (1000) is suppressed and rapid fluctuations in indoor temperature are prevented, thereby enabling the effect of efficiently reducing energy consumption.

[0055] FIG. 3 schematically illustrates the process of performing the cooling setting reception step (S100) according to one embodiment of the present invention.

[0057] As illustrated in FIG. 3, the air conditioner control method includes a cooling setting receiving step (S100) for receiving base information including the operating cycle of the air conditioner (1000), the operating time of the air conditioner (1000), and the target indoor temperature input from a user terminal (5000).

[0059] In summary, FIG. 3(a) illustrates an exemplary user interface provided to a user terminal (5000), and FIG. 3(b) illustrates the process of performing a cooling setting reception step (S100).

[0061] As an embodiment of the present invention illustrated in FIG. 3(a), a user interface provided by a service server (3000) linked to the user terminal (5000) may be output to the user terminal (5000), and a plurality of control parameters including the operating cycle of the air conditioner (1000), the operating time of the air conditioner (1000), and a target indoor temperature may be displayed on the user interface.

[0062] The user can set the plurality of control parameters by selecting or inputting them through the user interface. For example, the operating cycle of the air conditioner (1000) can be set to 60 minutes, the operating time of the air conditioner (1000) to 15 minutes, and the target indoor temperature to 25℃, and the setting information of the operating cycle, operating time, and target indoor temperature input by the user can be transmitted to the service server (3000) through the user terminal (5000) as base information.

[0063] The above service server (3000) can transmit the base information to the control system (2000) through the server network (4000).

[0065] Meanwhile, in FIG. 3(a), the user terminal (5000) is depicted as a smartphone, but the user terminal (5000) is not limited thereto and may correspond to various types of terminal devices such as tablets, wall pads, and remote controls.

[0066] For example, the control system (2000) may further include a signal receiving module (not shown) capable of receiving a signal transmitted from a remote control, and may receive base information input by a user by physically operating a button of the remote control.

[0067] In addition, as another embodiment of the present invention, the control system (2000) can set the operation cycle, operation time, and target indoor temperature based on environmental information sensed from indoors without user input.

[0069] FIG. 4 illustrates timer cooling performed by a conventional air conditioner (1000) as an example.

[0071] As illustrated in FIG. 4, timer cooling performed by a conventional air conditioner (1000) is operated in such a way that the air conditioner (1000) is operated for a preset operating time (R) for each operating cycle (P), and the operation of the air conditioner (1000) is stopped during idle time (I).

[0073] Duty Ratio refers to the ratio of the time a device actually operates within a specific cycle, and the duty ratio of the air conditioner (1000) can be calculated using the following [Equation 1].

[0074]

[0075] At this time, D corresponds to the duty ratio of the air conditioner (1000).

[0077] As an embodiment of the present invention, when a user sets the operation cycle (P) to 60 minutes and the operation time (R) to 10 minutes, the air conditioner (1000) operates for 10 minutes every hour and stops for 50 minutes, and at this time the duty ratio of the air conditioner (1000) is calculated to be 16.7%, and the air conditioner (1000) repeats operation and stop with a constant duty ratio every operation cycle (P).

[0079] Meanwhile, in the area indicated by the dotted line in Figure 4, the indoor temperature repeatedly drops excessively, which can lead to a decrease in indoor temperature comfort and energy waste.

[0080] In other words, while conventional timer cooling can perform cooling repeatedly at regular intervals according to the duty cycle set by the user, it is structured in a way that cannot reflect changes in the indoor environment or external conditions in real time, so there may be a problem in that it is difficult to precisely control the operation time (R) of the cooling unit (1000) to flexibly adjust it or minimize temperature deviations.

[0082] FIG. 5 schematically illustrates the duty ratio of a cooling unit (1000) that is variably controlled according to the environment by a control system (2000) according to one embodiment of the present invention, and FIG. 6 exemplarily illustrates the process of performing an operation time correction step (S200) according to one embodiment of the present invention.

[0084] As illustrated in FIGS. 5 and 6, the air conditioner control method comprises: an operation time correction step (S200) that corrects the operation time based on environmental information related to the indoor space where cooling is performed for each operation cycle (P) and the base information; and a duty cycle cooling control step (S300) that controls the air conditioner (1000) to operate in a first mode to perform indoor cooling so that the indoor temperature reaches the target indoor temperature during the corrected operation time for each operation cycle (P), and to operate the air conditioner (1000) in a second mode to perform indoor cooling so that the indoor temperature maintains the target indoor temperature during the idle time excluding the operation time in the corresponding operation cycle (P), or to stop the operation of the air conditioner (1000).

[0085] Additionally, the duty cycle cooling control step (S300) includes: a cooling check step for calculating the temperature difference between the current indoor temperature and the target indoor temperature at the time of entering idle time for each operation cycle (P); and a mode switching step for stopping the operation of the air conditioner (1000) when the temperature difference between the current indoor temperature and the target indoor temperature is greater than or equal to a preset threshold temperature difference, and controlling the air conditioner (1000) to operate in the second mode when the temperature difference between the current indoor temperature and the target indoor temperature is less than the threshold temperature difference.

[0087] As an embodiment of the present invention illustrated in FIG. 5, in order to maintain the average indoor temperature close to the target indoor temperature during the operation cycle (P), the first mode performs cooling so that the indoor temperature can reach a temperature lower than the target indoor temperature, thereby allowing the indoor temperature to be maintained below a certain level even during idle time.

[0089] Specifically, through the execution of the above operation time correction step (S200), the air conditioner (1000) is repeatedly controlled based on a constant operation cycle (P), and the operation time is corrected based on the above environment information and the above base information for each operation cycle (P).

[0090] As an embodiment of the present invention, the corrected operating time for each operating cycle (P) can be set to R1, R2, R3, R4, and R5, respectively, and accordingly, the idle time can be changed to I1, I2, I3, I4, and I5, respectively.

[0092] Meanwhile, as an embodiment of the present invention illustrated in FIG. 6, the air conditioner control method according to the present invention, which variably controls the duty ratio according to the environment, unlike conventional timer cooling, can perform more flexible and precise cooling control by using an initial duty ratio input by a user as a reference and correcting the corresponding duty ratio by considering real-time environmental information.

[0093] For example, if a user inputs an operation cycle (P) of 60 minutes and an operation time of 10 minutes, and the initial duty cycle of the air conditioner (1000) is set to 16.7%, the control system (2000) can variably control the initial duty cycle based on the environment information and readjust the operation time for each operation cycle (P).

[0094] As another embodiment of the present invention, the control system (2000) can achieve the effect of simplifying the operation pattern and ensuring the stability of the cooling control by applying a preset fixed operating time to the air conditioner (1000) without variably controlling the duty ratio according to the environment when specific conditions are met.

[0096] In addition, the duty cooling control step may include a cooling check step that calculates the temperature difference between the current indoor temperature and the target indoor temperature at the point when the corrected operating time for each operating cycle (P) ends and the idle time is entered.

[0097] As an embodiment of the present invention, after the air conditioner (1000) has been operated in the first mode for an operating time R1, the temperature difference between the current indoor temperature and the target indoor temperature can be calculated at the time of entering the idle time I1, and a mode switching step can be performed to determine whether to control the air conditioner (1000) to operate in the second mode or to stop the air conditioner (1000) during the idle time based on the temperature difference between the current indoor temperature and the target indoor temperature.

[0098] For example, when entering idle time, if the current indoor temperature is 2°C or lower than the target indoor temperature, the operation of the air conditioner (1000) can be stopped to prevent excessive cooling and reduce energy consumption.

[0099] Meanwhile, if the current indoor temperature is lower than the target indoor temperature, but the temperature difference between the current indoor temperature and the target indoor temperature is less than 2℃, the air conditioner (1000) can be operated in the second mode to maintain the indoor temperature at a level similar to the target indoor temperature.

[0100] In addition, if the current indoor temperature does not reach the target indoor temperature during the above operating time due to a rapid rise in the outside temperature or an indoor environment with a large heat inflow, the air conditioner (1000) can be operated in the second mode to prevent a rapid rise in the indoor temperature.

[0102] FIG. 7 schematically illustrates an operation time correction step (S200) according to one embodiment of the present invention.

[0104] As illustrated in FIG. 7, the environment information includes the current indoor temperature, and the operation time correction step (S200) can correct the operation time in a direction that increases the operation time of the corresponding operation cycle when the current indoor temperature is higher than the target indoor temperature, and correct the operation time in a direction that decreases the operation time of the corresponding operation cycle when the current indoor temperature is lower than the target indoor temperature.

[0106] As an embodiment of the present invention, a temperature sensor may be placed in a form embedded in a cooling unit (1000) or a control system (2000), and the temperature sensor may measure the indoor temperature in real time.

[0107] The above-mentioned operation time correction unit (2200) can determine the level of heat to be supplied to the indoors during the corresponding operation cycle by comparing the current indoor temperature measured through the temperature sensor with the target indoor temperature included in the base information input from the user terminal (5000).

[0108] Specifically, if the current indoor temperature is higher than the target indoor temperature, the operation time correction unit (2200) can determine that additional cooling is required in the corresponding operation cycle and perform correction of the operation time in a direction that increases the operation time of the operation cycle.

[0109] Meanwhile, if the current indoor temperature is lower than the target indoor temperature, the operation time correction unit (2200) can determine that additional cooling is not significantly needed in the corresponding operation cycle and can perform correction of the operation time in a direction that reduces the operation time of the operation cycle.

[0110] In one embodiment of the present invention, by dynamically correcting the operating time of the corresponding operating cycle by reflecting the heat demand predicted based on the current temperature of the room where cooling is performed, the effect of improving the flexibility of the air conditioner (1000) control and the indoor temperature stability can be achieved.

[0112] FIG. 8 schematically illustrates a cooling trend derivation step and a trend-based correction step according to one embodiment of the present invention.

[0114] As illustrated in FIG. 8, the environmental information further includes the average indoor temperature during the previous operating cycle, and the operating time correction step (S200) includes: a cooling trend derivation step that derives a trend of indoor temperature change based on the average indoor temperature during the previous operating cycle and the current indoor temperature at the time of entering the current operating cycle; and a trend-based correction step that corrects the operating time of the corresponding operating cycle by reducing or increasing it based on the trend of indoor temperature change.

[0116] Specifically, the control system (2000) can collect indoor temperatures measured in real time during the previous operation cycle through the temperature sensor and calculate the average of the collected indoor temperatures as the average indoor temperature during the previous operation cycle.

[0117] The above-mentioned operation time correction unit (2200) can derive a trend of indoor temperature change and determine the level of heat to be supplied to the indoors during the operation cycle by comparing the calculated average indoor temperature with the current indoor temperature at the point of entry into the current operation cycle.

[0118] More specifically, if the above average indoor temperature is higher than the above current indoor temperature, the above operation time correction unit (2200) can interpret that the indoor temperature is trending downward and determine that the amount of cooling can be reduced during the corresponding operation cycle, and can perform correction in the direction of reducing the operation time of the operation cycle.

[0119] Meanwhile, if the above average indoor temperature is lower than the above current indoor temperature, the control system (2000) may interpret that the indoor temperature is trending upward and determine that it is necessary to reinforce cooling during the corresponding operation cycle, and may perform a correction in the direction of increasing the operation time of the operation cycle.

[0120] In one embodiment of the present invention, by performing dynamic cooling control that reflects the trend of indoor temperature change by comparing the previous operating cycle with the current temperature state, it is possible to achieve the effect of enabling precise correction considering the external temperature change and the temperature inertia characteristics according to the indoor structure.

[0122] FIG. 9 illustrates an exemplary thermal energy profile according to one embodiment of the present invention.

[0124] As illustrated in FIG. 9, the environmental information further includes a thermal energy profile that determines the increase or decrease of the operating time based on the change in thermal energy by the sun over time, and the operating time correction step (S200) further includes a solar radiation-based correction step that corrects the operating time of the corresponding operating cycle by reducing or increasing it based on the thermal energy profile.

[0126] As an embodiment of the present invention illustrated in FIG. 9, the thermal energy profile may include information on the amount of change in radiant heat energy radiated to the ground by sunlight over time during a 24-hour period and the amount of change in heat energy accumulated on the ground by sunlight.

[0127] The above thermal energy profile can be calculated based on real-time information collected through solar radiation information received from an external server (6000) via a server network (4000) and regional weather information, and the control system (2000) can utilize the above thermal energy profile to perform cooling control for each operating cycle of the corresponding time period more precisely.

[0129] Specifically, since the most thermal energy is stored in the ground by sunlight around 3 PM on the thermal energy profile, and thus the amount of natural heat flowing into the room is relatively large, it corresponds to a time period when the indoor temperature is likely to rise, so the operation time correction unit (2200) can correct the operation time in a direction that increases the operation time of the air conditioner (1000) for the operation cycle of that time period.

[0130] Meanwhile, around 6 a.m., just before dawn, is the time when the thermal energy stored in the ground is at its lowest, and since the natural rise of the indoor temperature is limited, the above-mentioned operation time correction unit (2200) can correct the operation time in a direction that reduces the operation time of the air conditioner (1000) for the operation cycle of the early morning time.

[0132] In addition, since radiant heat energy can be transferred into the room through windows, walls, and ceilings from immediately after sunrise to immediately before sunset in the above thermal energy profile, the above time period is considered to be a time period in which natural heat accumulation and indoor temperature rise are easy, and the above operating time correction unit (2200) can correct the operating time of the air conditioner (1000) in a direction that increases the operating time of the operating cycle of the above time period.

[0133] Meanwhile, the nighttime period from sunset to just before sunrise is a time period in which there is no inflow of radiant heat energy and is a time period in which there is a low possibility of a rapid rise in indoor temperature; therefore, the above-mentioned operation time correction unit (2200) can correct the operation cycle of the corresponding time period in a direction that reduces the operation time of the air conditioner (1000).

[0135] In one embodiment of the present invention, by adjusting the operating time of the air conditioner (1000) for each time period by considering the time-based inflow characteristics of thermal energy stored in the ground and solar radiation, it is possible to prevent rapid changes in indoor temperature, thereby maintaining a comfortable cooling environment and simultaneously reducing unnecessary energy consumption.

[0137] FIG. 10 schematically illustrates a forecast-based correction step according to one embodiment of the present invention.

[0139] As illustrated in FIG. 10, the environmental information further includes weather information including the current temperature of the region where the control system (2000) is located, and the operation time correction step (S200) further includes a forecast-based correction step in which, if the current temperature is higher than the current indoor temperature, the correction is performed in the direction of increasing the operation time of the corresponding operation cycle, and if the current temperature is lower than the current indoor temperature, the correction is performed in the direction of decreasing the operation time of the corresponding operation cycle; and the control system (2000) can decrease or increase the operation time of the operation cycle in proportion to the difference between the current temperature and the current indoor temperature.

[0141] Specifically, the control system (2000) can receive weather information, including the current temperature of the area where the control system (2000) and the air conditioner (1000) are located, in real time from an external server (6000) via a server network (4000).

[0142] The above control system (2000) can determine the level of heat to be supplied to the indoors during the corresponding operation cycle by comparing the current temperature with the current indoor temperature measured through the temperature sensor.

[0143] More specifically, when the current temperature is higher than the current indoor temperature, there is a high possibility that the indoor temperature will rise due to heat inflow from the outside, so the operation time correction unit (2200) can correct the operation time in a direction that increases the operation time of the corresponding operation cycle.

[0144] Meanwhile, if the above current temperature is lower than the above current indoor temperature, it can be determined that the target indoor temperature can be reached with relatively less cooling because the possibility of cold air inflow from the outside is high. Therefore, the above operation time correction unit (2200) can correct the operation time in a direction that reduces the operation time of the corresponding operation cycle.

[0146] As an embodiment of the present invention, the operation time correction unit (2200) can correct the operation time based on the following [Equation 2].

[0147]

[0148]

[0149]

[0150] At this time, T o is the current temperature, T c is the current indoor temperature, C1 is the first correction time, k1 is the sensitivity coefficient based on the temperature difference between the current air temperature and the current indoor temperature, R a is the corrected operating time, and R b This corresponds to the initial operation time based on user settings.

[0151] In addition, the above k1 can be set to vary according to the size of the above △T1, and since the larger the above △T1, the higher the possibility of excessive correction of the operating time, this configuration is intended to prevent the operating time of the air conditioner (1000) from being excessively sensitive to changes in the outdoor environment.

[0152] As an embodiment of the present invention, when △T1 is 1℃, the influence of the outdoor temperature on the indoor temperature is limited, so the sensitivity of the cooling control can be maintained high and the value of k1 can be set relatively large to 1.0.

[0153] Meanwhile, when the above △T1 is 10℃, an excessively large correction amount is applied, which may cause the air conditioner (1000) to operate excessively or result in unnecessary energy consumption. Therefore, by setting the above k1 to a relatively low value such as 0.5, the increase range of the above C1 is limited, and the response of the control system (2000) is mitigated, thereby enabling more stable cooling control.

[0154] For example, R b ga is 10 minutes and T o Ga 35℃, T c If α is 25℃ and k1 is set to 0.3, C1 is calculated as 3 min, and accordingly R a = can be corrected to 13 minutes.

[0156] FIG. 11 illustrates an exemplary saving parameter and saving factor according to one embodiment of the present invention.

[0158] As illustrated in FIG. 11, the control system (2000) determines a correction time to reduce or increase the operating time of the corresponding operating cycle in proportion to the absolute value of the difference between the target indoor temperature and the current indoor temperature, and applies a pre-set saving coefficient corresponding to the saving parameter to the correction time for a saving parameter selected through the user terminal (5000) among a plurality of saving parameters stored in the control system (2000).

[0160] As an embodiment of the present invention, the operation time correction unit (2200) included in the control system (2000) can determine the correction time through the following [Equation 3].

[0161]

[0162]

[0163]

[0164] At this time, T t is the target indoor temperature, T c is the current indoor temperature, C2 is the second correction time, k2 is the sensitivity coefficient based on the temperature difference between the target indoor temperature and the current indoor temperature, R a is the corrected operating time, and R b This corresponds to the initial operation time based on user settings.

[0165] In addition, just like k1 described above in the description of FIG. 10, k2 can be set to vary according to the size of △T2, and since the larger △T2 is, the higher the possibility of excessive correction of the operating time, this configuration is intended to prevent the operating time of the air conditioner (1000) from being excessively sensitive to changes in the outdoor environment.

[0166] For example, R b ga is 10 minutes and T t Ga 25℃, T c If α is 30℃ and k2 is set to 0.6, C2 is calculated as 3 min, and accordingly R a = can be corrected to 13 minutes.

[0168] In addition, a plurality of saving parameters may be pre-set and stored in the control system (2000), and by applying a saving coefficient corresponding to a saving parameter selected by the user through the user terminal (5000) to the correction time, the operating time of the air conditioner (1000) can be flexibly controlled according to the saving parameters.

[0169] As an embodiment of the present invention illustrated in FIG. 11, the saving parameter may be composed of five modes: 'saving saving', 'saving', 'balanced', 'hot and cold bath', and 'hot and cold bath', and the 'balanced' mode corresponds to a default mode that applies a reference coefficient (saving coefficient 1.0).

[0170] Meanwhile, the above-mentioned saving parameters may be classified according to the aggressiveness of cooling operation or the level of energy saving, and the above-mentioned 'saving-saving' mode exhibits the highest energy saving tendency, while the above-mentioned 'cold bath hot bath' mode may correspond to a mode that performs the most aggressive cooling operation.

[0171] More specifically, the first saving factor applied when correcting to increase the operating time according to each saving parameter and the second saving factor applied when correcting to decrease the operating time can be set differently. For example, if the operating time correction unit (2200) needs to correct the operating time in a direction that increases the operating time, and the correction time C2 = 4 minutes is calculated, then in the 'saving saving' mode , in the above 'saving' mode , in the above 'Balance' mode , in the above 'hot and cold bath' mode , in the above 'cold bath hot bath' mode final correction time This can be decided.

[0173] Accordingly, as an embodiment of the present invention, the operation time correction unit (2200) can calculate the final correction time by applying the saving factor as shown in [Equation 4] below.

[0174]

[0175]

[0176] At this time, γ corresponds to the saving factor corresponding to the saving parameter selected by the user.

[0177] For example, R b = 10 minutes, T t = 25℃, T c = 30℃, k2= 0.6, when the economy parameter is in 'Economy' mode,

[0178]

[0179]

[0180]

[0181] The final operation time is determined by this.

[0182] In one embodiment of the present invention, by flexibly adjusting the correction strength according to the selected saving parameter, the operating time of the air conditioner (1000) can be controlled more precisely to match the user's energy-saving tendencies and operating purpose.

[0184] Preferably, the operating time correction unit (2200) determines the final corrected operating time by comprehensively summing or selectively applying the correction times calculated through each of the correction steps described above, and controls the air conditioner (1000) to operate in a first mode based on the operating time, thereby minimizing the deviation of the indoor temperature and maximizing energy usage efficiency.

[0186] Meanwhile, as another embodiment of the present invention, an upper limit and a lower limit for the operating time of the air conditioner (1000) may be pre-set and mapped for each mode in correspondence with the saving parameter, and if the calculated correction time exceeds the upper limit or falls below the lower limit, the operating time correction unit (2200) can prevent excessive or insufficient operation of the air conditioner (1000) by readjusting the correction time to the upper limit or lower limit.
