  For example, when the operation mode set in the indoor units 10a-10i is the cooling operation and the temperature unevenness in the air-conditioning target space RM determined by the temperature unevenness determination unit 36b is the floor temperature unevenness, as shown in FIG. The summer clock rotation (rotation direction j = 1) and the summer counterclockwise rotation (rotation direction j = 2) are sequentially performed. Further, for example, when the operation mode set in the indoor units 10a-10i is the cooling operation, and the temperature unevenness in the air-conditioning target space RM determined by the temperature unevenness determination unit 36b is the vertical temperature unevenness, it is shown in FIG. Thus, X axis + direction rotation (rotation direction k = 1), X axis-direction rotation (rotation direction k = 2), Y axis + direction rotation (rotation direction k = 3), and Y axis-direction rotation (Rotation direction k = 4) are sequentially performed.

  In addition, as shown in FIG. 15, the 1st driving | operation process part 36c implements several pattern sets each selected from several pattern sets twice.

  Moreover, the 1st driving | operation process part 36c performs a 1st temperature nonuniformity elimination driving | operation, when the information regarding the required pattern set is not memorize | stored in the determination pattern storage area 35i mentioned above. That is, for example, when the operation mode set for the indoor units 10a to 10i is the cooling operation, and the temperature unevenness determined by the temperature unevenness determination unit is the floor temperature unevenness, J in column FF3 in FIG. Only when the pattern set is not stored in the first operation processing unit 36c, the first operation processing unit 36c performs the above-described processing.

d) Time measurement unit The time measurement unit 36d measures the temperature unevenness elimination time. Specifically, the time measurement unit 36d measures the time until the temperature unevenness is resolved after each pattern set is started by the first operation processing unit 36c based on the time counted by the timer unit 34. . The time measured by the time measuring unit 36d is stored in the unevenness elimination time storage area 35g described above. Note that the values stored in the unevenness elimination time storage area 35g are stored in association with the corresponding pattern sets, as indicated by FF1 and FF1 in FIG.

e) Average Value Calculation Unit The average value calculation unit 36e calculates the average value of the temperature unevenness elimination time measured by the time measurement unit 36d described above. Specifically, the average value calculation unit 36e calculates an average value of two temperature unevenness elimination times measured by the time measurement unit 36d for one pattern set. That is, since the first operation processing unit 36c causes the indoor units 10a to 10i to perform one pattern set twice, the time measurement unit 36d measures the time taken for one pattern set to eliminate the temperature unevenness twice. To do. Therefore, the average value calculation unit 36e calculates the average value of the two temperature unevenness elimination times measured by the time measurement unit 36d. The average value calculated by the average value calculation unit 36e is stored in the average value storage area 35h described above. Note that the values stored in the average value storage area 35h are stored in association with the corresponding pattern sets as indicated by FF2 and FF2 in FIG.

f) Pattern Set Determining Unit The pattern set determining unit 36f determines a pattern set to be executed by the second operation processing unit 36g described later based on the average value calculated by the average value calculating unit 36e. Specifically, the pattern set having the smallest value among the average values of several pattern sets implemented by the first operation processing unit 36c is determined as the pattern set to be executed by the second operation processing unit 36g. For example, when summer clock rotation (rotation direction j = 1) and summer counterclockwise rotation (rotation direction j = 2) are performed, the average value of summer clock rotation (rotation direction j = 1) is summer. When the counterclockwise rotation (rotation direction j = 2) is smaller than the average value, the summer clock rotation (rotation direction j = 1) is determined as a pattern to be executed by the second operation processing unit 36g. That is, when the control for generating the swirl flow of the summer clock rotation (rotation direction j = 1) is performed, the control for generating the swirl flow of the summer counterclockwise rotation (rotation direction j = 2) is performed. Since the temperature unevenness is eliminated as soon as possible, the pattern set determination unit 36f selects the rotation direction j = 1 in which the temperature unevenness is resolved quickly. The pattern set determined by the pattern set determination unit 36f is stored in the determined pattern storage area 35i described above. The pattern set stored in the determined pattern storage area 35i is stored in association with each type of temperature unevenness, as indicated by FF3 and FF3 in FIG.

g) Second operation processing unit The second operation processing unit 36g stores the pattern set stored in the determined pattern storage area 35i and the wind direction pattern storage area 35c when the temperature unevenness is determined by the temperature unevenness determination unit 36b. Based on the made wind direction pattern, a temperature unevenness elimination operation (second temperature unevenness elimination operation) suitable for the air-conditioning target space RM is performed. As described above, the temperature unevenness eliminating operation is a flow of air that swirls in the air conditioning target space RM in order to interlock the indoor units 10a-10i and greatly agitate the air in the air conditioning target space RM to eliminate the temperature unevenness. It is the driving | operation which produces | generates. The 2nd driving | operation process part 36g produces | generates the control command for controlling indoor unit 10a-10i based on the pattern set memorize | stored in the determination pattern memory area 35i as 2nd temperature nonuniformity elimination driving | operation.

h) Control Command Transmitting Unit The control command transmitting unit 36h is configured based on the control commands generated by the first operation processing unit 36c and the second operation processing unit 36g and the command input from the input unit 33. A control command is transmitted to 10i.

<Temperature unevenness elimination operation>
Next, the flow of processing in the controller 30 for causing the indoor units 10a to 10i to perform the temperature unevenness eliminating operation will be described using FIG.

  First, in step S100, initial parameter values are set to 1 (j, k, l, m, o, p, q, r = 1).

  Next, in step S101, the air conditioner information acquisition unit 36a acquires the operation data of the indoor units 10a-10i and stores the operation data in the air conditioner information storage area 35f. As described above, the operation data includes values detected by the suction temperature sensors 13a, 13a,... And the floor temperature sensors 13c, 13c,.

  Thereafter, the process proceeds to step S102, where the temperature unevenness determination unit 36b is stored in the operation data stored in the air conditioner information storage area 35f, the zone information stored in the zone information storage area 35a, and the determination condition storage area 35e. Based on the determination condition, the temperature unevenness state is determined in the air-conditioning target space RM. Specifically, the temperature unevenness determination unit 36b determines whether the temperature unevenness is equal to or less than a threshold value. If the temperature unevenness is equal to or smaller than the threshold value in step S102, the process returns to step S101. If the temperature unevenness is greater than the threshold value, the process proceeds to step S103.

  In step S103, it is judged by the 1st driving | operation process part 36c whether the rotation direction is determined. Specifically, whether or not any rotation direction corresponding to the operation mode set in the indoor units 10a to 10i and the temperature unevenness state determined by the temperature unevenness determination unit 36b is determined (determined rotation). The directions J, K, L, and M (whether FF3 and FF3 in FIG. 15 have been set) are determined. For example, when the operation mode set for the indoor units 10a-10i is the cooling operation and the temperature unevenness determined by the temperature unevenness determination unit 36b is the floor temperature unevenness, some value is entered in the field of the determined rotation direction J. Is stored. If it is determined in step S103 that the rotation direction has been determined, the process proceeds to step S105. If it is determined that the rotation direction has not been determined, the process proceeds to step S104.

  In step S104, the operation mode for determining the rotation direction is switched (rotation direction determination mode). In step S104, the pattern set used by the second operation processing unit 36g for the second temperature unevenness elimination operation is determined (FIG. 15, determined rotation directions J, K, L, and M). The rotation direction determination mode will be described in detail in <Description of rotation direction determination mode> below. When the rotation direction is determined in step S104, the process returns to step S101.

  In step S105, the second operation processing unit 36g generates a control command based on the pattern set stored in the determined pattern storage area 35i (second temperature unevenness eliminating operation). In addition, the control command is transmitted to the indoor units 10a-10i by the control command transmission unit 36h.

  Then, it progresses to step S106, operation data is acquired from indoor unit 10a-10i, and the said operation data are memorize | stored in the air conditioner information storage area 35f. Further, in step S107, the temperature unevenness determination unit 36b determines the state of temperature unevenness based on the operation data stored in the air conditioner information storage area 35f. Specifically, the temperature unevenness determination unit 36b determines whether the temperature unevenness is equal to or less than a threshold value. If the temperature unevenness is equal to or smaller than the threshold value in step S107, the process returns to step S101 to start the normal operation. If the temperature unevenness is larger than the threshold value, the process proceeds to step S108. The normal operation is a basic operation mode that is performed in advance by the indoor units 10a to 10i, such as a cooling operation or a heating operation, rather than an operation based on the pattern set.

  In step S108, it is determined whether or not a predetermined time has elapsed since the second temperature unevenness elimination operation was performed. If it is determined in step S108 that the predetermined time has not elapsed, the process waits until the predetermined time elapses. If the predetermined time has elapsed, the process returns to step S101 to start normal operation. .

<Description of rotation direction determination mode>
Next, the rotation direction determination mode will be described with reference to FIGS. 17A to 18C. As described above, the rotation direction determination mode determines the pattern set (symbol FF3, determined rotation directions J, K, L, and M in FIG. 15) used by the second operation processing unit 36g for the second temperature unevenness elimination operation. Mode.

  First, in step S200, the type of temperature unevenness is determined. If the type of temperature unevenness determined in step S200 is vertical temperature unevenness, the process proceeds to step S220 shown in FIG. 18A, and if it is floor temperature unevenness, the process proceeds to step S201.

  In step S201, the first operation processing unit 36c determines the operation mode set for the indoor units 10a-10i. In step S201, when the operation mode determined by the first operation processing unit 36c is the cooling operation mode, the process proceeds to step S202. When the operation mode is the heating operation mode, the process proceeds to step S211 in FIG. 17C.

  In step S202, a control command based on the pattern set is generated. Specifically, a control command is generated based on a pattern set that generates a horizontally rotating air flow. More specifically, a control command based on a pattern set (rotation direction j = 1 or j = 2) that generates a horizontally rotating air flow during cooling is generated (see FIG. 15). Thereafter, a control command is transmitted to the indoor units 10a-10i. When the control command is transmitted to the indoor units 10a-10i, the process proceeds to step S203, and the timer unit 34 starts counting. Next, it progresses to step S204 and driving | operation data are acquired by the air conditioner information acquisition part 36a. The operation data acquired by the air conditioner information acquisition unit 36a is stored in the air conditioner information storage area 35f. Thereafter, the process proceeds to step S205.

  In step S205, the temperature unevenness determination unit 36b determines the state of temperature unevenness based on the information stored in the air conditioner information storage area 35f. Specifically, the temperature unevenness determination unit 36b determines whether the temperature unevenness is equal to or less than a threshold value. If the temperature unevenness is not less than or equal to the threshold value in step S205, the process returns to step S204 and waits until the temperature unevenness becomes equal to or less than the threshold value. If the temperature unevenness is equal to or less than the threshold value in step S205, the process proceeds to step S206.

  In step S206, based on the time counted by the timer unit 34, the time measuring unit 36d measures the time taken until the temperature unevenness is eliminated, and the measured result is stored in the unevenness elimination time storage area 35g. The

  Thereafter, the process proceeds to step S207, where it is determined whether j is smaller than 2. In step S207, when j is smaller than 2, the process proceeds to step S208, and when j is 2 or more, the process proceeds to step S209. In step S208, a value obtained by adding 1 to j is substituted for j, and then the process returns to step S101. On the other hand, in step S209, it is determined whether o is smaller than 2. In step S209, when o is smaller than 2, the process proceeds to step S210, 1 is substituted for j, a value obtained by adding 1 to o is substituted for o, and then the process returns to step S101. On the other hand, if o is 2 or more in step S209, the process ends.

  Next, in step S201, when it is not in the cooling operation mode, the process proceeds to step S211 (see FIG. 17C). In step S211, a control command based on the pattern set is generated. Specifically, a control command is generated based on a pattern set that generates a horizontally rotating air flow. More specifically, a control command based on a pattern set (rotation direction 1 = 1 or 1 = 2) that generates a horizontally rotating air flow during heating is generated (see FIG. 15). Thereafter, a control command is transmitted to the indoor units 10a-10i. When the control command is transmitted to the indoor units 10a-10i, the process proceeds to step S212, and the timer unit 34 starts counting.

  Next, it progresses to step S213 and driving | operation data are acquired by the air conditioner information acquisition part 36a. The operation data acquired by the air conditioner information acquisition unit 36a is stored in the air conditioner information storage area 35f. Thereafter, the process proceeds to step S214.

  In step S214, the temperature unevenness determination unit 36b determines the temperature unevenness state. Specifically, the temperature unevenness determination unit 36b determines whether the temperature unevenness is equal to or less than a threshold value. In step S214, if the temperature unevenness is not less than or equal to the threshold value, the process returns to step S213 and waits until the temperature unevenness becomes equal to or less than the threshold value. If the temperature unevenness is equal to or less than the threshold value in step S214, the process proceeds to step S215.

  In step S215, based on the time counted by the timer unit 34, the time measurement unit 36d measures the time taken until temperature unevenness is eliminated, and stores the measured result in the unevenness elimination time storage area 35g.

  Thereafter, the process proceeds to step S216, where it is determined whether l is smaller than 2. In step S216, if l is smaller than 2, the process proceeds to step S217, and if l is 2 or more, the process proceeds to step S218. In step S217, a value obtained by adding 1 to l is substituted for l, and then the process returns to step S101. On the other hand, in step S218, it is determined whether q is smaller than 2. In step S218, when q is smaller than 2, the process proceeds to step S219, in which 1 is substituted for l, a value obtained by adding 1 to q is substituted for q, and then the process returns to step S101. On the other hand, if q is 2 or more in step S218, the process ends.

  Next, when the temperature unevenness is the vertical temperature unevenness in step S200, the operation mode set for the indoor units 10a-10i is determined by the first operation processing unit 36c in step S220 (FIG. 18A). The In step S220, when the operation mode determined by the first operation processing unit 36c is the cooling operation mode, the process proceeds to step S221. When the operation mode is the heating operation mode, the process proceeds to step S230 (see FIG. 18C). .

  In step S221, a control command based on the pattern set is generated. Specifically, a control command is generated based on a pattern set that generates a vertically rotating air flow. More specifically, a control command based on a pattern set (rotation direction k = 1, k = 2, k = 3, or k = 4) that generates a vertically rotating air flow during cooling is generated (see FIG. 15). Thereafter, a control command is transmitted to the indoor units 10a-10i. When the control command is transmitted to the indoor units 10a-10i, the process proceeds to step S222, and the timer unit 34 starts counting.

  Next, it progresses to step S223 and driving | operation data are acquired by the air conditioner information acquisition part 36a. The operation data acquired by the air conditioner information acquisition unit 36a is stored in the air conditioner information storage area 35f. Thereafter, the process proceeds to step S224.

  In step S224, the temperature unevenness determination unit 36b determines the temperature unevenness state. Specifically, the temperature unevenness determination unit 36b determines whether the temperature unevenness is equal to or less than a threshold value. If the temperature unevenness is not less than or equal to the threshold value in step S224, the process returns to step S223 and waits until the temperature unevenness becomes equal to or less than the threshold value. If the temperature unevenness is equal to or smaller than the threshold value in step S224, the process proceeds to step S225.

  In step S225, based on the time counted by the timer unit 34, the time measuring unit 36d measures the time taken until the temperature unevenness is eliminated, and stores the measured result in the unevenness elimination time storage area 35g.

  Thereafter, the process proceeds to step S226, where it is determined whether k is smaller than 4. In step S226, when k is smaller than 4, the process proceeds to step S227, and when k is 4 or more, the process proceeds to step S228. In step S227, a value obtained by adding 1 to k is substituted for k, and then the process returns to step S101. On the other hand, in step S228, it is determined whether p is smaller than 2. If p is smaller than 2 in step S228, the process proceeds to step S229, 1 is substituted for k, a value obtained by adding 1 to p is substituted for p, and then the process returns to step S101. On the other hand, if p is 2 or more in step S228, the process is terminated.

  On the other hand, if it is not the cooling operation mode in step S220, a control command based on the pattern set is generated in step S230. Specifically, a control command is generated based on a pattern set that generates a vertically rotating air flow. More specifically, a control command based on a pattern set (rotation direction m = 1, m = 2, m = 3, or m = 4) that generates a vertically rotating air flow during heating is generated (see FIG. 15). Thereafter, a control command is transmitted to the indoor units 10a-10i. When the control command is transmitted to the indoor units 10a-10i, the process proceeds to step S231, and the timer unit 34 starts counting. Next, it progresses to step S232 and driving | operation data are acquired by the air conditioner information acquisition part 36a. The operation data acquired by the air conditioner information acquisition unit 36a is stored in the air conditioner information storage area 35f. Thereafter, the process proceeds to step S233.

  In step S233, it is determined by the temperature nonuniformity determination part 36b whether temperature nonuniformity is below a threshold value. In step S233, if the temperature unevenness is not less than or equal to the threshold value, the process returns to step S232 and waits until the temperature unevenness becomes equal to or less than the threshold value. In step S233, if the temperature unevenness is equal to or smaller than the threshold value, the process proceeds to step S234.

  In step S234, based on the time counted by the timer unit 34, the time measurement unit 36d measures the time taken until the temperature unevenness is eliminated, and stores the measured result in the unevenness elimination time storage area 35g.

  Thereafter, the process proceeds to step S235, where it is determined whether m is smaller than 4. In step S235, when m is smaller than 4, the process proceeds to step S236, and when m is 4 or more, the process proceeds to step S237. In step S236, a value obtained by adding 1 to m is substituted for m, and then the process returns to step S101. On the other hand, in step S237, it is determined whether r is smaller than 2. In step S237, when r is smaller than 2, the process proceeds to step S238, in which 1 is substituted for m, a value obtained by adding 1 to r is substituted for r, and then the process returns to step S101. On the other hand, if r is 2 or more in step S237, the process ends.

<Feature>
(1)
When a relatively wide indoor space such as an office mentioned as an example in the above embodiment is an air-conditioning target space RM, temperature unevenness is likely to occur in the air-conditioning target space RM. Therefore, it is conceivable that a plurality of indoor units 10a-10i are provided in the room, and the indoor air is stirred by swinging the flaps 12a-12d of the indoor units 10a-10i. However, it may be difficult to sufficiently eliminate the temperature unevenness depending on the indoor layout and the position of the window. In addition, it is conceivable to increase the effect of eliminating temperature unevenness by entering the indoor layout and window position individually, but it is changed whenever the indoor unit is introduced into the room or the room layout changes. It is complicated to input the information.

  In the air conditioning control system 100 according to the present embodiment, the temperature unevenness determination unit 36b as the air conditioning unevenness grasping unit determines and grasps temperature unevenness in the air conditioning target space RM. Then, based on the type of the temperature unevenness, the pattern set determining unit (air conditioning unevenness eliminating optimum operation determining unit) 36f automatically determines the temperature unevenness eliminating operation suitable for the air conditioning target space RM. The second operation processing unit 36g as the air conditioning unevenness eliminating operation unit is automatically determined in this way, and executes the temperature unevenness eliminating operation suitable for the air conditioning target space RM. For this reason, even when the internal layout of the air-conditioning target space RM is changed, the temperature unevenness generated in the air-conditioning target space RM is effective without making complicated settings such as inputting changed information. Can be eliminated.

(2)
In the air conditioning control system 100 according to the above embodiment, as shown in FIG. 2B, a plurality of pattern sets are stored in the controller 30 in order to eliminate temperature unevenness in the horizontal direction (lateral direction) and the vertical direction (vertical direction). Has been. The pattern set is a combination of a plurality of wind direction patterns. Indoor unit 10a-10i changes the inclination (opening degree) of a flap according to the wind direction pattern sent to each. That is, a large flow of air swirling in the air-conditioning target space RM can be generated by interlocking control of the plurality of indoor units 10a-10i. Thereby, indoor air can be greatly stirred. As a result, the temperature unevenness generated in the air conditioning target space RM can be effectively eliminated.

(3)
Furthermore, in the air conditioning control system 100 according to the above-described embodiment, the controller 30 has a pattern set corresponding to the operation mode set in the indoor units 10a-10i. That is, the controller 30 sends a control command for generating different air flows to the indoor units 10a to 10i in the cooling period and the heating period. Thereby, in addition to the temperature non-uniformity determined by the temperature non-uniformity determination unit 36b, a more effective temperature non-uniformity elimination operation according to the season can be performed.

(4)
In the above embodiment, the temperature unevenness determination unit 36b determines the temperature unevenness state of the air-conditioning target space RM. As the temperature unevenness state, if there is temperature unevenness, and if there is temperature unevenness, the type of temperature unevenness, the location of the temperature unevenness, the degree of temperature unevenness are judged, and the pattern set that eliminates temperature unevenness is selected first. The Thereby, the indoor unit can execute the most suitable pattern set according to the state of temperature unevenness (type, location, and degree of temperature unevenness).

<Modification>
(A)
In the above embodiment, the floor temperature sensors 13c, 13c,... Are installed in all the indoor units 10a-10i, and the temperature unevenness determination unit is obtained from all the floor temperature sensors 13c, 13c,. However, only one of the indoor units 10a-10i may be provided with the floor temperature sensors 13c, 13c,. Further, in this case, the controller 30 may be provided with a bed temperature estimation unit that estimates the bed temperature in the other zones Z1 to Z9 using values obtained from some of the bed temperature sensors 13c, 13c,. . Thereby, in the air conditioning control system 100, an indoor unit which does not have a floor temperature sensor can be substituted for some of the plurality of indoor units. In this case, it is sufficient that at least two indoor units have floor temperature sensors.

  In the above embodiment, the indoor temperature is determined using the suction temperature sensors 13a, 13a, and 13a, but other sensors that the indoor unit has may be used instead of the suction temperature sensors 13a, 13a, and 13a.

  In the above embodiment, an example in which temperature unevenness is determined using values detected by the suction temperature sensors 13a, 13a, 13a and the floor temperature sensors 13c, 13c, 13c attached to the indoor units 10a-10i is described. However, the suction temperature sensor and the floor temperature sensor may be separate from the indoor unit.

(B)
Although the floor temperature unevenness and the upper and lower temperature unevenness are stored as the types of temperature unevenness in the determination condition storage area 35e, the present invention is not limited to this, and other temperature unevenness conditions may be defined. For example, conditions for cases where both floor temperature unevenness and vertical temperature unevenness occur simultaneously, or when unevenness occurs only in one place in the room, may be defined.

(C)
In the above embodiment, the air flow swirling in the air-conditioning target space RM in the horizontal direction has been described with reference to an example of the air flow that forms one large vortex as shown in FIGS. 10A to 10D. As shown in (a) and (b), a plurality of vortex air flows may be generated. Specifically, control based on a plurality of pattern sets is performed simultaneously in one air conditioning target space RM. For example, the air-conditioning target space RM is divided into two regions, and a summer clock rotation vortex is generated in one region, and a summer counterclockwise vortex is generated in the other region. Thereby, even when there are a plurality of locations of temperature unevenness determined by the temperature unevenness determination unit 36b, the temperature unevenness can be appropriately eliminated according to the state of temperature unevenness at each location.

(D)
Moreover, you may control the indoor unit 10a-10i by combining the some pattern set quoted in the said embodiment as an example, and one pattern set containing several pattern sets.

(E)
In the above embodiment, the pattern set whose average value calculated by the average value calculation unit 36e is the smallest value is determined by the pattern set determination unit 36f as one pattern set to be executed by the second operation processing unit 36g. It was done. However, the pattern set determination unit 36f may prioritize the average value calculated by the average value calculation unit 36e, and the second operation processing unit 36g may perform the pattern set based on the priority order. Specifically, the pattern set determination unit 36f assigns a higher priority in ascending order of the average value calculated by the average value calculation unit 36e. First, the second operation processing unit 36g controls the indoor units 10a to 10i based on the highest priority pattern set. Thereafter, if the temperature unevenness is not resolved within a predetermined time, the indoor units 10a to 10i are controlled based on the pattern set having the next highest priority. In this way, the optimum temperature can be obtained even when the layout of the air-conditioning target space RM is changed after the pattern set for performing the temperature unevenness elimination operation most suitable for the air-conditioning target space RM is once determined. Uneven operation can be performed.

(F)
In the above-described embodiment, temperature unevenness is described as an example of air conditioning unevenness that is eliminated by the air conditioning control system 100. However, in the air conditioning control system 100, instead of temperature unevenness or in addition to temperature unevenness, humidity unevenness, Unevenness such as CO ₂ concentration unevenness, airflow speed unevenness, radiation amount unevenness, dust amount unevenness, formaldehyde amount and the like can also be eliminated. In this case, a sensor for detecting each value is provided in the indoor units 10a-10i. Further, the controller 30 stores determination conditions for determining each unevenness in the determination condition storage area 35e. Thereby, it may be considered that other unevenness may be eliminated instead of or in addition to the temperature unevenness in the air conditioning target space RM.

(G)
In the above-described embodiment, “time from when temperature unevenness is determined until temperature unevenness is resolved” is used as the temperature unevenness elimination time averaged by the average value calculation unit 36e, but “temperature unevenness is determined. A value obtained by correcting “time until temperature unevenness is eliminated” may be used as the temperature unevenness elimination time. For example, a value obtained by dividing "time taken to eliminate temperature unevenness" by "temperature range of temperature unevenness resolved" and / or "time taken to resolve temperature unevenness" to "difference between outside temperature and set temperature" A value divided by “” may be used.

  Further, instead of “time until temperature unevenness is resolved after temperature unevenness is determined”, a pattern set may be determined based on “degree of temperature unevenness cancellation in a predetermined time”. Thereby, it is possible to reduce the time spent until the pattern set is determined.

In the above embodiment, “temperature difference” is stored as a condition for determining the presence or absence of temperature unevenness, but the determination condition is not limited to this. For example, when the predetermined temperature difference occurs more than a predetermined number of times, when the predetermined temperature difference continues for a predetermined time (minutes) or more, or when the average temperature difference in the room is equal to or higher than the predetermined temperature, the temperature unevenness It may be determined that there is.

(I)
In the above embodiment, whether or not there is temperature unevenness is determined based on the operation data acquired by the air conditioner information acquisition unit 36a based on whether or not the difference in temperature (instantaneous value) exceeds a predetermined threshold. The temperature unevenness determination is not limited to this. For example, temperature unevenness is determined by comparing the maximum value / minimum value / moving average value over a certain period instead of instantaneous values, and determining temperature unevenness when temperature unevenness over a threshold continues for a certain period of time. Also good.

(J)
In the determination condition storage area 35e according to the embodiment, the floor temperature unevenness and the upper and lower temperature unevenness are stored as conditions used when the temperature unevenness determination unit 36b determines the state of temperature unevenness. This condition may be set according to the operation mode (cooling operation mode and heating operation mode).

(K)
In the above embodiment, the optimal rotation direction for eliminating the temperature unevenness is determined by the first temperature unevenness eliminating operation by the first operation processing unit 36c. However, the optimal rotation direction is set in advance regardless of the above method. It may be designed so that control is performed based on the setting.

(L)
Moreover, in the said embodiment, in order to eliminate temperature nonuniformity, indoor unit 10a-10i was controlled based on the pattern set memorize | stored in the determination pattern memory area 35i. Here, if the temperature unevenness is not resolved even if the indoor units 10a-10i are controlled based on the pattern set stored in the determined pattern storage area 35i, the control based on the same pattern set is repeated. Therefore, the number of repetitions is counted, and when the number of repetitions exceeds a predetermined value, the current rotation direction is set to a rotation direction that has been previously assigned a priority or a newly determined rotation direction. It may be designed to change.
