<How to start the operation of the air conditioner>
The control device 10 uses the first storage unit 12 and the first control unit 14 to execute a method of determining the operation mode of the air conditioner. Hereinafter, a method of determining the operation mode of the air conditioner using the form of the control device 10 shown in FIG. 1A will be described, but the method can also be applied to the form of the control device 10 shown in FIG. 1A. is there. FIG. 2 is a flowchart of a method for determining the operation mode of the air conditioner according to the first embodiment, and the method for determining the operation mode of the air conditioner includes the following steps S100 to S400.

The first control unit 14 acquires the indoor temperature of the control space of the air conditioner via the indoor temperature sensor 24 at the start of operation of the air conditioner, and the indoor temperature acquired at the start of operation and the set temperature of the air conditioner 20 are combined with each other. The temperature difference of (step S100) is calculated. Then, the first control unit 14 controls the operation of the air conditioner 20 at a limit level that limits the output upper limit value of the compressor of the air conditioner 20 in a predetermined target time from the start of the operation of the air conditioner 20. (Step S200). The target time is the operating time from the start of operation of the air conditioner 20, and is a preset time. As the target time, for example, a time such as 5 minutes, 10 minutes, or 15 minutes from the start of the operation of the air conditioner 20 may be set. The first control unit 14 detects and monitors the indoor temperature of the control space of the air conditioner 20 via the indoor temperature sensor 24, and causes the indoor temperature of the control space to reach the set temperature of the compressor 26. Control driving. Preferably, the first control unit 14 controls the operation of the compressor 26 so that the indoor temperature of the control space reaches the set temperature immediately before the expiration of the target time.

The first control unit 14 can control the output of the compressor 26 or limit the output upper limit value by limiting the rotation frequency or the current value of the motor of the compressor 26. .. The limit level is an index indicating the degree to which the output upper limit value of the compressor 26 is limited. The first control unit 14 may set a plurality of limit levels and specify one limit level for the air conditioner 20 to limit the output upper limit value of the compressor 26 of the air conditioner 20. For example, the limit levels are set to 0 (ie, no limit), 1-3, and each limit level is one frequency that is the upper limit of the motor rotation of the compressor 26, or a ratio to the output upper limit value (for example, 50). %, 60%, 80%) may be supported. In one embodiment, the higher the limit level, the more the output upper limit value of the compressor 26 is limited, and the lower the output upper limit value is set. Further, the limit level is set to 0 as a default for the compressor 26.

The limit level may be stored in the first storage unit 12, the second storage unit 21, or the two storage units 12, 21 together with the limit level and the actual output upper limit value (ratio, frequency, current value, etc.). The collation table of the above may also be stored in the first storage unit 12, the second storage unit 21, or the two storage units 12, 21. When the collation table between the limit level and the output upper limit value is stored in the second storage unit 21, in step S200, the first control unit 14 reads out the limit level of the compressor 26 from the first storage unit 12 and obtains the first. 1 Transmission is performed to the air conditioner 20 via the communication unit 16. The second control unit 22 collates the collation table in the second storage unit 21 with the limit level received from the control device 10 via the second communication unit 23, reads the actual output upper limit value, and reads the actual output upper limit value. The operation of the compressor 26 is controlled using the output upper limit value. The first control unit 14 reads the output upper limit value corresponding to the limit level of the compressor 26 from the first storage unit 12, transmits the output upper limit value to the air conditioner 20 via the first communication unit 16, and compresses the output. The operation of the machine 26 may be controlled by the output upper limit value.

Next, the first control unit 14 monitors the indoor temperature of the control space and acquires the time required for the indoor temperature to reach the target temperature related to the set temperature (step S300). The target temperature is a temperature before reaching the set temperature, and there is a temperature difference between the set temperature and a predetermined value. For example, in the cooling mode (hereinafter abbreviated as cooling), the target temperature is 0.5 ° C. higher than the set temperature, and in the heating mode (hereinafter abbreviated as heating), the target temperature is 0.5 than the set temperature. The temperature is low. The operation of the air conditioner 20 is not immediately reflected in the room temperature of the control space. Excessive operation and power consumption can be avoided by setting the target temperature and weakening the operation of the air conditioner 20 when the room temperature reaches the target temperature before the set temperature. The first control unit 14 measures the elapsed time from the start of operation by the timer 27 while monitoring the indoor temperature of the control space by the indoor temperature sensor 24. When the indoor temperature of the control space reaches the target temperature, the timer 27 stops the measurement and notifies the first control unit 14 of the measurement result as the required time.

FIG. 3 is an example of the target time and the required time in the first embodiment. The output of the compressor 26 and the room temperature of the control space are shown so that they can be observed side by side on the same time axis. As described above, the target time is a fixed predetermined period, and the air conditioner 20 is controlled so that the indoor temperature of the control space becomes the set temperature by the expiration of the target time. Generally, the required time is shorter than the target time. In particular, due to the improvement in the operating efficiency of the air conditioner 20, if the compressor 26 is operated at the limit level 0, that is, if it is operated at the maximum output, the required time may be considerably shorter than the target time.

The first control unit 14 updates the limit level based on the temperature difference calculated in step S100 and the required time acquired in step S300 (step S400). For example, if the temperature difference between the indoor temperature at the start of operation and the set temperature is large, but the time required to reach the target temperature is short, the limit level is increased. Further, when determining a new limit level, the limit level may be increased according to, for example, the length of the required time or the time difference between the target time and the required time. In one embodiment, when the calculated time difference exceeds the predetermined time difference threshold value and the acquired required time is smaller than the predetermined time threshold value, the limit level of the air conditioner 20 is increased by 1. In another embodiment, when the number of times the time difference exceeds the predetermined number of times threshold value exceeds the predetermined number of times, the limit level is raised by one step. On the other hand, if the operating situation is such that the temperature difference is small but the required time is long, the limit level may be lowered.

The updated limit level of the air conditioner 20 is stored in the first storage unit 12 or the second storage unit 21 again. At the next start of operation of the air conditioner 20, the process returns to step S100, and the first control unit 14 reads the updated limit level and controls the operation of the air conditioner at the updated limit level at the target time. Therefore, when the limit level is raised in step S400, the limit amount with respect to the output upper limit value of the compressor 26 becomes larger, and the compressor 26 is operated at the output upper limit value limited from the previous time at the start of the next operation. In this way, by accumulating updates, the control device 10 can learn the limit level suitable for the compressor 26 and the control space of the air conditioner 20.

As a result, the first control unit 14 controls the operation of the air conditioner at the limit level, and the process of updating the limit level according to the operating condition is completed. Then, when the air conditioner 20 is restarted, it operates at the updated limit level. According to the method of starting the operation of the air conditioner and the control device, the control device 10 updates the limit level according to the operating condition at the start of the operation of the air conditioner 20, so that the air conditioner 20 and the control device 20 and the control device 10 are updated. A limit level suitable for the control space can be set, and excessive power consumption can be suppressed.

<When updating the limit level using the limit level judgment value>
In the second embodiment, instead of updating the limit level directly, the limit level is updated in two steps via the limit level determination value. In this embodiment, there are a plurality of limit levels, and each limit level corresponds to one determination value range.

The limit level determination value is a variable used when determining the limit level, and the first control unit 14 sets the limit level to which the determination value range to which the limit level determination value belongs actually corresponds to the current limit level. The first control unit 14 may set at least one limit level determination value in one air conditioner 20.

Table 1 is an example of a collation table between the judgment value range and the limit level. In this example, the minimum value of the limit level judgment value is 0, the maximum value is 40, and 4 from the minimum value to the maximum value. Two judgment value ranges are defined. This collation table can be stored in the first storage unit 12, the second storage unit 21, or the two storage units 12, 21.

FIG. 4 is a flowchart of an example of a method of starting the operation of the air conditioner according to the second embodiment. Similar to the first embodiment, the first control unit 14 calculates the temperature difference between the room temperature acquired at the start of operation and the set temperature (step S100). Then, the first control unit 14 controls the operation of the air conditioner 20 at the limit level at the target time (step S200), and acquires the required time (step S300). Step S400 in the first embodiment includes steps S410 and S420 here. That is, in order to update the limit level, the first control unit 14 first updates the limit level determination value of the air conditioner 20 based on the temperature difference and the required time (step S410). In step S410, the first control unit 14 allows the air conditioner 20 to update the limit level determination value based on the operating condition at the target time. For example, it is considered that the larger the temperature difference, the longer the required time, and the shorter the required time, the excessively set the output upper limit value of the compressor 26. Therefore, according to the combination of the temperature difference and the required time, it is possible to determine whether or not the current output upper limit value of the compressor 26 is appropriate, and the limit level determination value and the limit level are appropriately updated. Can be done.

FIG. 5 is a flowchart of an example of step S410 in the second embodiment. In one embodiment, the first control unit 14 selects one from a plurality of calculation formulas based on the combination of the temperature difference and the required time (step S510). In order to relate the combination to the plurality of calculation formulas, the possible combinations of the temperature difference and the required time are divided into a plurality of regions, and each region corresponds to one calculation formula. FIG. 6 is an example of a region used for selecting a calculation formula in the second embodiment. As shown in FIG. 6, the set of possible combinations of the temperature difference and the required time is defined by the first to fourth regions defined by the first to third curves, and the first to fourth regions are defined by the first to third curves. Each of the 1st to 4th regions corresponds to one formula. In the embodiment of FIG. 6, a second curve such as a fold line is defined using the first temperature difference threshold to the third temperature difference threshold and the first time threshold to the third time threshold. The first curve and the third curve, such as a polygonal line, are curves in which the second curve is displaced downward or upward, respectively, using the same displacement value. The first region is the region below the first curve. The second region is the region between the information on the first curve and the second curve. The third region is the region between the information of the second curve and the third curve. The fourth region is the region above the third curve.
Table 2 below is an example of a collation table showing the correspondence between the area and the calculation formula. The collation table of this area and the calculation formula can be stored in the first storage unit 12, the second storage unit 21, or the two storage units.

The reference value in Table 2 may be any positive number for convenience of calculation, for example, 1. In this case, the calculation formula corresponding to the first area is "add 2 to the limit level judgment value", and the calculation formula corresponding to the second area is "add 1 to the limit level judgment value". The calculation formula corresponding to the third area is "the limit level judgment value as it is", and the calculation formula corresponding to the fourth area is "subtract 1 to the limit level judgment value".

In step S510, the first control unit 14 determines the region to which the combination of the calculated temperature difference and the acquired required time belongs, collates Table 2, and selects a calculation formula. Then, the first control unit 14 updates the limit level determination value of the air conditioner 20 based on the selected calculation formula (step S520). For example, in step S200, when the limit level determination value is 19, the limit level is 1, and the region to which the combination of the calculated temperature difference and the required time belongs is the second region, the first control unit 14 determines. The calculation formula "add 1 to the limit level judgment value" corresponding to the second region is selected, and 1 is added to the limit level judgment value to obtain the limit level judgment value of 20.

After updating the limit level determination value, the first control unit 14 updates the limit level based on the determination value range to which the updated limit level determination value belongs (step S420). For example, when the limit level judgment value becomes 20 as in the above-mentioned update, the corresponding judgment value range has changed from "10 ≦ limit level judgment value <20" to "20 ≦ limit level judgment value <30". 1 The control unit 14 updates the limit level from 1 to 2. The updated limit level determination value and limit level of the air conditioner 20 are stored in the first storage unit 12 or the second storage unit 21 again, and the output upper limit value of the compressor 26 is limited again at the next operation start. Read out. Depending on the selected calculation formula and the definition of the judgment value range, the limit level judgment value or limit level before and after the update may be the same.

As a result, the operation of controlling the operation of the air conditioner at the limit level is completed, and the process of updating the limit level determination value and the limit level based on the operating conditions such as the temperature difference and the required time is completed. Then, when the air conditioner 20 is restarted, it operates at the updated limit level. According to the method of starting the operation of the air conditioner and the control device, the limit level is updated stepwise using the limit level determination value, so that the limit can be appropriately limited by the output upper limit value of the compressor. By accumulating such updates, the control device 10 can more appropriately learn the limit level suitable for the compressor 26 and the control space of the air conditioner 20. Moreover, since the judgment value range and the calculation formula can be changed, it is easy to flexibly deal with different air conditioners.

<When updating the limit level judgment value according to the amount of solar radiation>
Generally, the amount of solar radiation received by the control space of the air conditioner 20 affects the indoor temperature of the control space, and also affects the ease of cooling or warming of the control space. In order to learn the limit level determination value and the limit level more accurately for a specific air conditioner and its control space, in the third embodiment, the air conditioner 20 has a solar radiation sensor 25 and is an air conditioner. The limit level determination value and the limit level can be updated according to the amount of solar radiation received by the 20 control spaces.

The air conditioner 20 has a configuration capable of detecting the amount of solar radiation in the control space at regular intervals by using a solar radiation sensor 25 or the like. The solar radiation sensor 25 is a sensor that detects the amount of solar radiation received by the control space. The solar radiation sensor 25 may be installed at a place where the amount of solar radiation can be detected. The solar radiation sensor 25 may be installed on the outer surface of the indoor unit or the outdoor unit of the air conditioner 20 so as to receive the solar radiation, for example. The information on the amount of solar radiation detected by the solar radiation sensor 25 is input to and stored in the air conditioning storage unit 21.

FIG. 7 is a flowchart of an example of step S400 in the third embodiment. Similar to the first embodiment and the second embodiment, the first control unit 14 calculates the temperature difference between the indoor temperature acquired at the start of operation and the set temperature (step S100), and air-conditions at a limit level at the target time. The operation of the machine 20 is controlled (step S200), and the required time is acquired (step S300). Then, the first control unit 14 of the third embodiment updates the limit level determination value and the limit level by executing step S400 including step S421 from step S411 below. It is considered that the following steps S411 to S414 are included in the above-mentioned step S410, and steps S421 and S422 are included in the above-mentioned step S420.

In the embodiment of FIG. 7, the first control unit 14 updates the limit level determination value and the limit level separately for the case with solar radiation and the case without solar radiation, and causes the first storage unit 12 or the second storage unit 21 to update. Remember. For the sake of case classification, in this embodiment, the limit level determination value includes the determination value with solar radiation and the determination value without solar radiation, and the determination value range includes the range with solar radiation and the range without solar radiation. Each of the judgment value with solar radiation and the judgment value without solar radiation is a limit level judgment value used in the case of with solar radiation and in the case of no solar radiation, and their definitions and properties are the same as those of the above-mentioned limit level judgment value, but are different. Stored or updated as a variable. Each of the range with and without solar radiation is a judgment value range used with and without solar radiation, and its definition and properties are the same as the above-mentioned judgment value range, but it is stored as a different variable or stored. Will be updated. The initial value, the minimum value, or the maximum value of these limit level judgment values (judgment value with solar radiation, judgment value without solar radiation), and the range of these judgment values (range with solar radiation, range without solar radiation) are the first storage unit. 12, the second storage unit 21, or the two storage units can be stored together.

In step S400, the first control unit 14 acquires the amount of solar radiation in the control space of the air conditioner 20 via the solar radiation sensor 25 (step S411). Next, the first control unit 14 selects a determination value with solar radiation or a determination value without solar radiation based on the acquired amount of solar radiation, and updates the selected limit level determination value based on the temperature difference and the required time.

Specifically, the first control unit 14 determines whether the acquired amount of solar radiation is equal to or greater than the amount of solar radiation threshold (step S412). When it is determined that the amount of solar radiation is equal to or greater than the amount of solar radiation threshold value, the first control unit 14 determines that the amount of solar radiation is actually present, and selects a determination value with solar radiation from the limit level determination value. In addition, in the determination of with or without solar radiation, the integrated amount or average value of the solar radiation amount within a predetermined time may be calculated, and it may be determined whether the integrated value or the average value is equal to or higher than the solar radiation amount threshold. .. The first control unit 14 updates the selected solar radiation determination value based on the temperature difference and the required time (step S413). Here, as described above, the first control unit 14 may select a suitable calculation formula based on the combination of the temperature difference and the required time, and update the determination value with solar radiation based on the selected calculation formula. .. Since the first control unit 14 has determined that the amount of solar radiation is equal to or greater than the amount of solar radiation, the first control unit 14 selects the range with solar radiation from the determination value range. Then, the restriction level is updated based on the selected solar radiation range (that is, the determination value range) to which the updated solar radiation determination value (that is, the limit level determination value) belongs (step S421). Here, the first control unit 14 sets the limit level corresponding to the range with sunlight to which the updated determination value with sunlight belongs as the limit level after update. When it is determined that the amount of solar radiation is equal to or greater than the threshold value of the amount of solar radiation, the first control unit 14 does not select the determination value with solar radiation and the range with solar radiation in steps, and the determination value with solar radiation and the solar radiation in the same step. You may select both the range and the range.

On the other hand, when it is determined that the amount of solar radiation is smaller than the threshold value of the amount of solar radiation, the first control unit 14 determines that there is actually no solar radiation, and selects a determination value without solar radiation and a range without solar radiation. The first control unit 14 updates the selected non-solar determination value based on the temperature difference and the required time (step S414). Here, as described above, the first control unit 14 may select a suitable calculation formula based on the combination of the temperature difference and the required time, and update the non-solar determination value based on the selected calculation formula. .. Then, the first control unit 14 updates the limit level based on the selected no-solar range (that is, the determination value range) to which the updated no-solar determination value (that is, the limit level determination value) belongs (step S422). ). Here, the first control unit 14 sets the limit level corresponding to the no-solar range to which the updated no-solar determination value belongs as the updated limit level.

This completes the process of controlling the operation of the air conditioner at the limit level and updating the limit level determination value and the limit level based on the operating conditions such as the temperature difference and the required time and the amount of solar radiation in the control space. Then, when the air conditioner 20 is restarted, it operates at the updated limit level. According to the method of starting the operation of the air conditioner and the control device, the amount of solar radiation received by the control space of the air conditioner 20 is taken into consideration, and the update is performed separately for the case with and without the solar radiation. It is possible to learn the limit level determination value and the limit level more accurately for the air conditioner and its control space.

The operation is controlled (step S200) and the required time is acquired (step S300). Then, the first control unit 14 of the fourth embodiment updates the limit level determination value and the limit level by executing step S300 including step S422-2 from step S411 below. It is considered that the following steps S411 to S414-2 are included in the above-mentioned step S410, and steps S421-1 and S422-2 are included in the above-mentioned step S420.

In the embodiment of FIG. 8, the first control unit 14 is divided into a case with solar radiation and a case without solar radiation, and in each case, further, when the operation mode of the air conditioner 20 is the heating mode, and Separate the case where the operation mode is cooling. In each case, the first control unit 14 updates the limit level determination value and the limit level and stores them in the first storage unit 12 or the second storage unit 21. For the sake of case classification, in this embodiment, the determination value with solar radiation includes the heating judgment value with solar radiation and the cooling judgment value with solar radiation, and the judgment value without solar radiation includes the heating judgment value without solar radiation and the cooling judgment value without solar radiation. .. In addition, the range with solar radiation includes the heating range with solar radiation and the cooling range with solar radiation, and the range without solar radiation includes the heating range without solar radiation and the cooling range without solar radiation.

Each of the heating judgment value with solar radiation, the cooling judgment value with solar radiation, the heating judgment value without solar radiation, and the cooling judgment value without solar radiation are the limit level judgment values used when the combination of the presence / absence of solar radiation and the operation mode is different. , Its definition and properties are similar to the limit level determination values described above, but are stored or updated as different variables. The heating range with solar radiation, the cooling range with solar radiation, the heating range without solar radiation, and the cooling range without solar radiation are also judgment value ranges used when the combination of the presence or absence of solar radiation and the operation mode are different, and their definitions and properties are as follows. Same as the judgment value range described above, but stored or updated as a different variable. The initial value, minimum value, or maximum value of these limit level judgment values (heating judgment value with solar radiation, cooling judgment value with solar radiation, heating judgment value without solar radiation, cooling judgment value without solar radiation), and the range of these judgment values ( The heating range with solar radiation, the cooling range with solar radiation, the heating range without solar radiation, and the cooling range without solar radiation) can be stored in the first storage unit 12, the second storage unit 21, or the two storage units.

In step S400, the first control unit 14 acquires the amount of solar radiation in the control space of the air conditioner 20 via the solar radiation sensor 25 (step S411). Next, based on the acquired amount of solar radiation and the operation mode of the air conditioner, a heating judgment value with solar radiation, a cooling judgment value with solar radiation, a heating judgment value without solar radiation, or a cooling judgment value without solar radiation is selected. In addition, the heating range with solar radiation, the cooling range with solar radiation, the heating range without solar radiation, or the cooling range without solar radiation is selected based on the acquired amount of solar radiation and the operation mode.

The first control unit 14 determines whether the acquired amount of solar radiation is equal to or greater than the amount of solar radiation threshold (step S412-1). When the first control unit 14 determines that the amount of solar radiation is equal to or higher than the solar radiation amount threshold value, it actually determines that there is solar radiation, while when it determines that the amount of solar radiation is smaller than the solar radiation amount threshold value, the first control unit 14 Is actually judged to be the case without solar radiation. In each of the cases with and without solar radiation, the first control unit 14 further determines whether the operation mode of the air conditioner 20 is heating or cooling (step S412-2 and step S412-3). Specifically, when the amount of solar radiation is equal to or higher than the amount of solar radiation threshold and the operation mode is heating, the heating judgment value with solar radiation and the heating range with solar radiation are selected as the limit level judgment value and the judgment value range, respectively. To. When the amount of solar radiation is equal to or higher than the amount of solar radiation threshold and the operation mode is cooling, the cooling determination value with solar radiation and the cooling range with solar radiation are selected as the limit level determination value and the determination value range, respectively. When the amount of solar radiation is smaller than the amount of solar radiation threshold and the operation mode is heating, the heating determination value without solar radiation and the heating range without solar radiation are selected as the limit level determination value and the determination value range, respectively. When the amount of solar radiation is smaller than the amount of solar radiation threshold and the operation mode is cooling, the cooling without solar radiation determination value and the cooling range without solar radiation are selected as the limit level determination value and the determination value range, respectively.

When there is sunlight and the operation mode is heating, the first control unit 14 updates the heating determination value with sunlight based on the temperature difference and the required time (step S413-1). Further, when there is sunlight and the operation mode is cooling, the first control unit 14 updates the cooling determination value with sunlight based on the temperature difference and the required time (step S413-2). Similarly, when there is no solar radiation and the operation mode is heating, the first control unit 14 updates the non-solar heating determination value based on the temperature difference and the required time (step S413-2). Further, when there is no solar radiation and the operation mode is cooling, the first control unit 14 updates the cooling without solar radiation determination value based on the temperature difference and the required time (step S413-4). In steps S413-1 to S413-4, as described above, a suitable calculation formula is selected based on the combination of the temperature difference and the required time, and the selected limit level determination value is determined based on the selected calculation formula. You may update it.

Then, in each of the above four cases, after updating the selected limit level determination value (that is, the heating determination value with solar radiation, the cooling determination value with solar radiation, the heating determination value without solar radiation, or the cooling determination value without solar radiation), The limit level is updated based on the judgment value range to which the updated limit level judgment value belongs (that is, the heating range with sunlight, the cooling range with sunlight, the heating range without sunlight, or the cooling range without sunlight) (steps S421-1 to). Step S421-4). Here, the first control unit 14 sets the limit level corresponding to the determination value range to which the updated limit level determination value belongs as the updated limit level.

<Specific example of updating the limit level>

FIG. 9 is an example of updating the limit level in the fifth embodiment. The first control unit 14 executes a method of starting the operation of the air conditioner according to the flowcharts of FIGS. 2 and 8 using Tables 1 and 2 described above. FIG. 9 shows that when there is solar radiation and the operation mode is cooling, the air conditioner 20 is operated multiple times to update the solar radiation cooling determination value and the corresponding limit level, and the compressor 26. Indicates that the output upper limit of is limited according to the limit level. The two graphs corresponding to the limit level 0 are the operation status and the update status in two consecutive operations, but the graphs corresponding to each of the limit levels 0 to 2 are not graphs due to continuous operation. Therefore, the cooling determination values with solar radiation corresponding to the restriction levels 1 and 2 are not continuously updated.

As shown in FIG. 9, when the limit level is 0 (the output upper limit of the compressor 26 is unlimited) and the operation is performed at the maximum output at the start of operation, the required time is considerably shorter than the target time. The room temperature was set to the target temperature. The first control unit 14 selects the cooling determination value with solar radiation as the limit level determination value, and updates the cooling determination value with solar radiation based on the calculation formula (for example, adding 2 to the cooling determination value with solar radiation). When such updates overlap and the cooling determination value with solar radiation exceeds 10, the first control unit 14 updates the limit level corresponding to the cooling determination value with solar radiation from 0 to 1. At the start of the next operation after the limit level is changed to 1, the compressor 26 operates at the limited output upper limit value, so that the required time is longer than when the limit level is 0. However, since the required time is still considerably shorter than the target time, the limit level has been updated from 1 to 2 as a result of repeated updates such that the cooling judgment value with solar radiation increases. At the start of the next operation, the compressor 26 operates at a further limited output upper limit value. If you drive at the limit level 2, the time difference between the required time and the target time approaches so that there is almost no time difference, and based on this time difference, the calculation formula for updating the cooling judgment value with solar radiation is "Limit level judgment value. "As is" is selected. When this happens, the cooling determination value with solar radiation and the corresponding limit level become stable, and the first control unit 14 learns the optimum limit level for the compressor 26 of the air conditioner 20 and the control space, and is excessive at the start of operation. Power consumption can be suppressed.

<Effect>
According to the method and control device for starting the operation of the air conditioner of the present disclosure, the operation is controlled at a limit level that limits the output upper limit value of the compressor of the air conditioner at the start of the operation of the air conditioner. It is possible to suppress excessive power consumption at the start of operation in order to properly update. In particular, since the limit level is updated according to the operating conditions at the start of operation of the air conditioner, it is possible to learn the limit level suitable for the air conditioner and its control space, and suppress excessive power consumption. can do. Further, if the limit level is updated in two steps using the limit level determination value, the limit can be appropriately limited by the output upper limit value of the compressor. Since the judgment value range and the calculation formula can be changed, it is easy to flexibly deal with different air conditioners.

Further, according to the method and control device for starting the operation of the air conditioner of the present disclosure, the amount of solar radiation received by the control space of the air conditioner is divided into cases with and without solar radiation, or the amount of solar radiation and Since the limit level judgment value and the limit level can be updated in four cases according to the operation mode of the air conditioner, the limit level judgment value and the limit level can be updated more accurately for a specific air conditioner and its control space. You can learn the limit level.
