Description

  The present invention relates to a control device for an air conditioner that can change the direction of wind supplied from a blowout port by controlling a flap disposed at the blowout port.

  2. Description of the Related Art Conventionally, a control device that controls a swing operation of an air conditioner is known (for example, Patent Document 1 (Japanese Patent Laid-Open No. 9-196435)). The control device sends a control command for changing the inclination of the flap to the air conditioner. Thereby, the flow of the air blown out from the air conditioner is swung up and down to stir the air in the room, thereby eliminating the uneven temperature distribution in the vertical direction of the air-conditioning target space. In particular, in Patent Document 1 (Japanese Patent Laid-Open No. 9-196435), the wind speed of the blowout is controlled by adjusting the width of the blowout opening according to the temperature of the blowout. Specifically, the control is performed so that the wind speed is reduced when the blowing temperature is low, and the wind speed is increased when the blowing temperature is high. As a result, it is possible to prevent a strong wind from being directly applied to the user when the blowing temperature is low, and to reduce the discomfort caused by the draft to the user.

  However, in Patent Document 1 (Japanese Patent Laid-Open No. 9-196435), the swing operation itself for adjusting the wind direction is a monotonous vertical movement, and only changes the wind speed in accordance with the change in the blowing temperature.

In FIG. 4, the horizontal axis indicates time, the vertical axis indicates the direction of the flap, and the transition of the direction over time is shown. In addition, in this figure, the swing operation | movement of one flap represented among the four flaps provided in one indoor unit 2 is shown, and one flap of the latter three flaps performs the completely same swing operation | movement. The swing operation is performed in a state where two flaps are out of time with respect to the other two flaps. Thus, in one indoor unit 2, two flaps are set as a pair to synchronize the swing operation. Further, in FIG. 4, one scale marked on the horizontal axis is 10 seconds. Moreover, the ratio of the opening of the blower outlets 21a-21d changes according to the direction of each flap 22a-22d. That is, in the case of horizontal blowing, it is in a slightly open state, and in the case of downward blowing, it is in a fully open state. And since the four flaps 22a-22d are each controlled by the fine open state and the full open state independently, the ratio of the air volume which blows off from the blower outlets 21a-21d changes according to the opening degree. For example, when two flaps are in the slightly open state and the two flaps are in the fully open state, the air volume of about 10% of the total air volume is respectively emitted from the air outlet where the flap in the slightly open state is located. Is blown out, and from the air outlet where the fully opened flap is located, a wind of about 40% of the total air volume blows out.

During the start-up period of cooling operation, the temperature of the air blown out from the air conditioner is not sufficiently low, and simply using horizontal blowing may not be effective for cooling, causing discomfort to the user. There are many. Moreover, if too much time is blown down, a warm wind will be applied to the user, which is considered to cause discomfort. Pattern 1 is set as a pattern to be performed during the start-up period of the cooling operation. In order to solve the above-described problem, the swing pattern has a variation in air volume immediately after the start of the cooling operation.

(2-2) Pattern 2 and Pattern 3 (Stable period of cooling operation mode)
The stable period of the cooling operation is a state after a sufficient amount of time has elapsed since the start of the cooling operation, and is a state where it has been determined that the blowing temperature blown out from the air conditioner has become sufficiently low. In the stable period of the cooling operation, the indoor space is divided into a cold air layer and a warm air layer. As described above, if the air in the space is biased in the temperature distribution with respect to the vertical direction, the efficiency of the air conditioning is lowered and the user is uncomfortable. However, in the case of cooling operation, if the wind supplied from the air outlet is directly applied to the user, there is a risk of giving the user an uncomfortable feeling due to the draft. Further, if the swing operation is a monotonous fixed pattern, the comfort felt by the user is gradually reduced. Therefore, in the stable period of cooling operation, in order to solve these problems, it is divided into the case where the temperature distribution is biased (when there is temperature unevenness) and the case where it is not (when there is no temperature unevenness). The optimum swing pattern is applied to each.

  Pattern 3 is a swing pattern similar to pattern 2. The part where pattern 3 is different from pattern 2 is the duration of the duration pattern. The duration of pattern 3 is obtained by replacing the duration tk2 (20 seconds) of pattern 2 with tk4 (40 seconds) and the duration tk4 (40 seconds) of pattern 2 with tk5 (80 seconds). That is, in Pattern 3, the predetermined duration (2nd, 4th, 6th, 8th) is twice as long as in Pattern 2. This means that the time interval from the bottom blowing of pattern 3 to the next bottom blowing is doubled. Pattern 3 is a swing pattern performed when the cooling operation is in a stable period and there is no temperature unevenness. Therefore, the frequency of down-blowing is 0.1 times per 10 seconds as compared with the case where there is temperature unevenness as in pattern 2. And few.

  Note that the pattern 2 may be a pattern in which the duration of keep in horizontal blowing is shortened by 10 seconds, for example. In this case, since the frequency of the bottom blowing is higher than that of the pattern 2, the temperature unevenness in the room can be eliminated.

  In the stable period of the cooling operation, the set temperature may be set to + T ° C. (for example, 1 ° C.). As a result, it is possible to reduce discomfort caused by the draft, and it is possible to drive while suppressing energy consumption.

(2-3) Pattern 4 (starting period of heating operation mode)
In the start-up period of the heating operation, the temperature of the air blown out from the air conditioner is not sufficiently high. It makes you feel uncomfortable. Moreover, warm wind cannot be sent to the lower part of the indoor space where the user is located in the state of horizontal blowing. Therefore, it is necessary to blow down at an appropriate frequency. Pattern 4 is a pattern performed during the start-up period of such a heating operation. In order to solve the above-described problem, the frequency of downward blowing immediately after the start of the heating operation is reduced.

(2-4) Pattern 5 and Pattern 6 (interim period of heating operation)
The intermediate period of the heating operation is a state in which the blowout temperature is higher than that in the start-up period of the heating operation but not yet sufficiently warmed. That is, the intermediate period of the heating operation is a state defined in stages from the start-up period of the heating operation to the stable period of the heating operation in which the blowout temperature is sufficiently warm and the room temperature is also warm. . And in the middle period of heating operation, it divides into two in steps. In the intermediate period of the heating operation, the blowout temperature is higher than that in the start-up period, so that the possibility of giving the user discomfort due to the draft is reduced even if the blow is performed more frequently than in the start-up period. Patterns 5 and 6 are swing patterns that are performed during the intermediate period of such heating operation, and the frequency of downward blowing is increased compared to the start-up period of the heating operation.

(2-5) Pattern 7 (stable period of heating operation)
The stable period of the heating operation is a state where the blowing temperature is sufficiently high and the room is sufficiently warmed. In the stable period of the heating operation, since the blowing temperature is higher than that in the intermediate period, even if the blowing is performed more frequently than in the start-up period, the possibility of giving the user discomfort due to the draft is reduced. Pattern 7 is a swing pattern that is performed during the stable period of such heating operation, and the frequency of downward blowing is further increased than in the intermediate period of heating operation.

(3) Swing interlocking control In the air conditioning apparatus 1, by performing swing interlocking control of the 16 indoor units, a large air current is generated over the entire indoor space to realize agitation of the air in the entire indoor space. Here, the swing interlocking control will be described with reference to FIGS. FIG. 5 is a plan layout view of 16 indoor units arranged in the indoor space. The 16 indoor units are assigned indoor unit IDs as shown in FIG. Further, the air conditioner 1 stores the layout diagram of the 16 indoor units in FIG. 5, and the layout status of the 16 indoor units is recognized by the indoor unit ID.

  In the swing interlocking control, as described above, the swing operations of the flaps 22a to 22d of the 16 indoor units 2 are interlocked. That is, 64 (4 × 16) flaps are interlocked to generate a large airflow (longitudinal circulation airflow) in the indoor space. A specific control method for the flaps 22a to 22d of the 16 indoor units 2 will be described. The 64 flaps are controlled based on the flap control table of FIG. The flap control table associates the flap ID with the position of each flap.

  Here, the “flap ID” is attached to all 64 flaps. For example, the flap ID “FID011” corresponds to the flap 22a of the indoor unit ID “INID01”. That is, the first two digits of the three-digit number part of the flap ID match the two-digit number of the indoor unit ID. For example, the four flaps of the indoor unit ID “INID06” are “FID061” to “ FID064 ". And the last one digit of the 3-digit number part of the flap ID indicates the position of the four flaps of each indoor unit 2. Specifically, the flap 22a arranged along the lower side of the square representing the indoor unit in FIG. 5 when the latter half of the 3-digit number part of the flap ID is 1 is shown. When the second digit of the 3-digit number part of the flap ID is 2, the flap 22b is arranged along the right side of the square representing the indoor unit 2 in FIG. When the last one digit of the 3-digit number part of ID is 3, the flap 22c arranged along the upper side of the square representing the indoor unit 2 in FIG. In the case where the number of one digit in the latter half of the digit portion is 4, the flap 22d is disposed along the left side of the square representing the indoor unit 2 in FIG. From the above, for example, in the case of “FID134”, the flap 22d is arranged along the left side of the square indicating the indoor unit 2 whose indoor unit ID is “INID13” in FIG. Become.

  In addition, the “positional state” here indicates whether each flap is in a horizontal blowing state or a bottom blowing state. Here, “H” indicates that the flap is in a state of horizontal blowing, and “V” indicates that the flap is in a state of downward blowing. The position state includes two states, a “1st” state (first state) and a “2nd” state (second state), and each of the flaps 22a to 22d has a first state and a second state. Will be repeated regularly.

  FIG. 7 is a view showing a state where the flaps 22a to 22d are blown out when the positions of the flaps 22a to 22d are in the first state. In FIG. 7, there is an ellipse that touches a square side indicating each indoor unit 2, and the position states (that is, the blowing state) of the flaps 22 a to 22 d arranged along the side in contact with the ellipse due to the size of the ellipse. Show. Here, the smaller ellipse shows that the flap placed along the side where the ellipse touches is horizontal blowing, and the larger ellipse shows that the flap placed along the side where the ellipse touches is blown down. It shows that there is.

  And by controlling each flap 22a-22d in this way, in the vicinity of the alternate long and short dash line L5, the air flow from the alternate long and short dash line L2 (that is, the one-dot chain line L1 side or the alternate long and short dash line L3 side) (see the arrow in FIG. 7) Occurs near the ceiling. Further, since the flaps (flap IDs “FID021” and “FID033”) arranged on the outer side of the alternate long and short dash line L1 in the vicinity of the alternate long and short dash line L5 are downward blowing, from the alternate long and short dash line L1 near the alternate long and short dashed line L5. Also, a downward airflow is generated in the outer space (see FIG. 8). Note that the same can be said for the space outside the alternate long and short dash line L3 (that is, a symmetrical airflow occurs with the alternate long and short dash line L2 as an axis). Further, since the position states of all the flaps are symmetrical with respect to the one-dot chain line L2 or the one-dot chain line L5, and are point-symmetric about the intersection of the one-dot chain line L2 and the one-dot chain line L5, The same thing can be said about what happens in the vicinity of the alternate long and short dash line L5 even if the plane is rotated 90 degrees around the intersection of the alternate long and short dash line L2 and the alternate long and short dash line L5. For this reason, the same airflow is also generated in the vicinity of the alternate long and short dash line L2. Here, FIG. 8 is a cross-sectional view taken along the line VIII-VIII when the state of the airflow in the indoor space in the state of FIG. 7 is divided along the alternate long and short dash line L2 or the alternate long and short dash line L5.

  In addition, by controlling each flap as in the indoor space in the state of FIG. 7, the airflow from the indoor unit ID “INID06” to the indoor unit ID “INID01” near the alternate long and short dash line L7 (see the arrow in FIG. 7) In addition, an airflow (see an arrow in FIG. 7) from the indoor unit ID “INID11” to the indoor unit ID “INID16” is generated near the ceiling. The airflow from the indoor unit ID “INID06” toward the indoor unit ID “INID01” is caused by the airflow blown downward from the flap IDs “FID011” and “FID012” of the indoor unit ID “INID01”. It flows downward in the vicinity of “FID012” (see FIG. 9). The same applies to the airflow from the indoor unit ID “INID11” to the indoor unit ID “INID16”. Furthermore, the same thing can be said about the airflow generated in the vicinity of the alternate long and short dash line L7 even if the plane is rotated by 90 degrees. Therefore, the same airflow is also generated on the alternate long and short dash line L8. Here, FIG. 9 is a cross-sectional view taken along the line IX-IX in the case where the state of the airflow in the indoor space in the state of FIG. 7 is divided by the one-dot chain line L7 or the one-dot chain line L8. As described with reference to FIGS. 7 to 9, when the positions of the flaps 22a to 22d are in the first state, the longitudinal swirling airflow is generated as shown in FIGS.

  FIG. 10 is a diagram showing a state in which each flap blows out when the position of each flap 22a to 22d is in the second state. In FIG. 10, there is an ellipse that touches a square side indicating each indoor unit as in FIG. 7, and the position states of the flaps 22a to 22d arranged along the side where the ellipse touches due to the size of the ellipse (that is, State).

  And by controlling each flap 22a-22d in this way, in the vicinity on the dashed-dotted line L5, the airflow which goes outside from the dashed-dotted line L2 (namely, the dashed-dotted line L1 side or the dashed-dotted line L3 side) (refer the arrow of FIG. 10). Occurs near the ceiling. Further, since the flaps (flap IDs “FID021” and “FID033”) arranged on the outer side of the alternate long and short dash line L1 in the vicinity of the alternate long and short dash line L5 are downward blowing, from the alternate long and short dash line L1 near the alternate long and short dashed line L5. Also, a downward airflow is generated in the outer space (see FIG. 11). Note that the same can be said for the space outside the alternate long and short dash line L3 (that is, a symmetrical airflow occurs with the alternate long and short dash line L2 as an axis). Further, since the position states of all the flaps are symmetrical with respect to the one-dot chain line L2 or the one-dot chain line L5, and are point-symmetric about the intersection of the one-dot chain line L2 and the one-dot chain line L5, The same thing can be said about what happens in the vicinity of the alternate long and short dash line L5 even if the plane is rotated 90 degrees around the intersection of the alternate long and short dash line L2 and the alternate long and short dash line L5. For this reason, the same airflow is also generated in the vicinity of the alternate long and short dash line L2. Here, FIG. 8 is a cross-sectional view taken along the line XI-XI when the state of the airflow in the indoor space in the state of FIG.

  Further, by controlling each flap as in the indoor space in the state of FIG. 10, the airflow from the indoor unit ID “INID01” to the indoor unit ID “INID06” in the vicinity of the alternate long and short dash line L7 (see the arrow in FIG. 10) In addition, an air flow (see an arrow in FIG. 10) from the indoor unit ID “INID16” to the indoor unit ID “INID11” occurs near the ceiling. The airflow from the indoor unit ID “INID01” toward the indoor unit ID “INID06” is caused by the airflow blown downward from the flap IDs “FID063” and “FID064” of the indoor unit ID “INID06”, and the flap ID “FID063”. And it flows downward in the vicinity of “FID064” (see FIG. 12). The same applies to the airflow from the indoor unit ID “INID16” to the indoor unit ID “INID11”. Further, since the position states of all the flaps are symmetric with respect to the one-dot chain line L2 or the one-dot chain line L5, and are point-symmetric about the intersection of the one-dot chain line L2 and the one-dot chain line L5, The same can be said about the airflow generated near the alternate long and short dash line L7 even if the plane is rotated 90 degrees around the intersection of the alternate long and short dash line L2 and the alternate long and short dash line L5. For this reason, the same airflow is generated on the alternate long and short dash line L8. Here, FIG. 12 is an XII-XII cross-sectional view when the state of the airflow in the indoor space in the state of FIG. 10 is divided along the alternate long and short dash line L7 or the alternate long and short dash line L8.

  In the swing interlocking control, as described above, a plurality of large vertical swirling airflows generated over the entire indoor space are generated by setting the flap position to the first state or the second state. And thereby, the interior space is agitated. In addition, the direction of the longitudinal swirling airflow is changed by periodically switching between the first state and the second state as well as making the longitudinal swirling airflow in only one direction. Thereby, the indoor space is efficiently stirred. If this swing interlocking control is not always performed, but only when the air-conditioning apparatus 1 determines that the temperature distribution in the indoor space is biased, the stirring effect can be utilized. It can contribute to making the space comfortable. In the swing interlocking control, two of the four flaps provided in one indoor unit are paired and interlocked. For example, by linking adjacent flaps, a horizontal airflow from the indoor unit ID “INID01” to the indoor unit ID “INID06” in FIG. 7 can be generated, and a vertical swirling airflow is generated over the entire indoor space. Can be part of the factor. Furthermore, the vertical swirling airflow is more effectively generated by combining the flap IDs “FID063” and “FID064” of the indoor unit ID “INID06” in FIG. Further, for example, by changing the pair set in the indoor unit periodically between the first state and the second state as in the indoor unit ID “INID02”, it is possible to easily generate the longitudinal swirling airflow.

<Features>
(1)
In the air conditioner 1 of the present embodiment, a single air conditioner is controlled in the indoor space by swinging all 64 flaps of the plurality of (16) indoor units 2 in conjunction with each other. It produces multiple air currents that are difficult to do.

  Therefore, the air conditioner 1 can stir the interior of the indoor space with a large airflow. For this reason, the deviation (temperature unevenness) of the temperature distribution in the indoor space can be efficiently eliminated. Thereby, the comfort of indoor space can be improved.

<Modification>
(1)
In the air conditioner 1 according to the above-described embodiment, the vertical turning that occurs over the entire indoor space by periodically changing the position of the flap between the first state and the second state as swing interlocking control. Although the stirring effect is enhanced by changing the direction of the airflow, not only the two states are changed, but the vertical swirling airflow generated over the entire indoor space, for example, by periodically changing the four states May be rotated 45 degrees at a time to further increase the stirring effect.

  FIG. 13 is a flap control table in this case. FIG. 14 is a view showing a state in which each flap blows out when the position of each flap in the flap control table of FIG. 13 is in the first state. 15 is an XV-XV cross-sectional view when FIG. 14 is divided by alternate long and short dash lines L4 to L6. FIG. 16 is a view showing a state where each flap blows out when the position of each flap in the flap control table of FIG. 13 is in the second state. FIG. 17 is a cross-sectional view taken along the line XVII-XVII when FIG. 16 is divided by a dashed line L7. FIG. 18 is a diagram showing a state in which each flap blows out when the position of each flap in the flap control table in FIG. 13 is in the third state. FIG. 19 is a cross-sectional view taken along the line XIX-XIX when FIG. 18 is divided by an alternate long and short dash line L8. FIG. 20 is a diagram showing a state where each flap blows out when the position of each flap in the flap control table of FIG. 13 is in the fourth state. 21 is an XXI-XXI cross-sectional view when FIG. 20 is divided by alternate long and short dash lines L1 to L3.

  And if the swing interlocking control of each flap is performed based on the flap control table of FIG. 13, in the case of the first state, a vertical swirl air flow parallel to the alternate long and short dash lines L4 to L6 is generated, and in the case of the second state. A vertical swirling air flow parallel to the alternate long and short dash line L7 is generated. In the third state, a vertical swirling air flow parallel to the alternate long and short dash lines L1 to L3 is generated. In a fourth state, the vertical swirling air flow parallel to the alternate long and short dash line L8. Airflow will be generated. The switching of the four flap states from the first state to the fourth state may be switched periodically from the first state to the second state, the third state, and the fourth state, or at random. May be. Thereby, the whole indoor space can be stirred more finely than performing the swing interlocking control of the said embodiment.

(2)
In the air conditioning apparatus 1 according to the above embodiment, the swing interlocking control is independent as a swing pattern different from the plurality of swing patterns. However, the present invention is not limited to this. For example, the movements of the plurality of swing patterns are assigned to the flap ID “FID011”. In the applied swing pattern, the horizontal blowing may be set as the first state, and the downward blowing may be set as the second state. Thereby, the swing interlocking control with a high stirring effect can be applied according to the swing pattern performed at that time. Therefore, the selected swing pattern can be changed according to the phase suitable for the air conditioning state such as the temperature distribution in the room. For this reason, the temperature nonuniformity which arises in air-conditioning object space can be eliminated. Thereby, the comfort of indoor space can be improved.

(3)
In the air conditioning apparatus 1 in the above embodiment, all 64 flaps are interlocked as swing interlock control. However, the present invention is not limited to this, and a plurality of flaps are interlocked so that a vertical swirling airflow is generated at least partially. It doesn't matter. For example, in the vicinity of the one-dot chain line L7 in FIG. 6, the flap IDs “FID011” and “FID012” are blown horizontally, and the flap IDs “FID063” and “FID064” are blown down, and the vertical turn that occurs in the left half of FIG. An air current can be generated. As described above, a longitudinal swirling airflow may be generated by interlocking at least the flap IDs “FID011”, “FID012”, “FID063”, and “FID064”. In this case, the air conditioner 1 has selected the indoor unit IDs “INID01” and “INID06” as the indoor unit 2 to be subjected to swing interlock control.

  Thereby, for example, when there is a bias in temperature distribution in only a part of the indoor space, the bias in the temperature distribution can be eliminated by performing swing interlock control of the flap so that a vertical swirling airflow is generated in that portion. . Moreover, the longitudinal circulation airflow can be generated in the optimum direction. For this reason, the temperature nonuniformity which arose in the space for air conditioning can be eliminated more efficiently. Thereby, the comfort of indoor space can be improved.

  Moreover, in the air conditioning apparatus 1 in the said embodiment, although all the indoor units are operated as swing interlocking control, you may make it drive only the indoor unit which produces not only this but a longitudinal circulation airflow. For example, in FIG. 7, only the indoor unit IDs “INID01” and “INID06” may be linked to generate a longitudinal circulation airflow by these two indoor units, or an airflow that interferes with the generated longitudinal circulation airflow. The indoor unit to be generated may be stopped.

(4)
In the air conditioning apparatus 1 according to the above-described embodiment, 16 indoor units are arranged. However, the number is not limited to this, and the number of indoor units according to the size of the space may be used. For example, FIG. 22 shows a case where there are nine indoor units. In FIG. 22, the square shape indicates the indoor unit. Even when nine indoor units as shown in FIG. 22 are arranged, the flaps of all the indoor units can be controlled from the first state to the fourth state. Thereby, the longitudinal circulation airflow can be generated in various directions, and the air in the indoor space can be efficiently stirred.

(5)
In the air conditioning apparatus 1 according to the above embodiment, 16 indoor units are arranged in a grid pattern, but the present invention is not limited to this, and for example, the indoor units may be arranged in a non-grating pattern as shown in FIG. FIG. 23 shows an example of the position state of all the flaps when the indoor units are arranged in a non-lattice form. In FIG. 23, the square shape indicates the indoor unit. For example, by controlling the flap as shown in FIG. 23, a longitudinal circulation airflow can be generated, and the indoor space can be efficiently stirred.

(6)
In the air conditioner 1 according to the above-described embodiment, the indoor unit is a four-direction blowout type indoor unit in which four flaps are mounted on one unit. It may be a one-way type indoor unit.

  FIG. 24 shows the position of the flaps for swing-linked control (four ways) in the two-way blowing type indoor unit, and FIG. 25 shows the position of the flaps for swing-linked control in the one-way blowing type indoor unit. The states (two ways) are shown. In addition, in FIG.24, 25, the thing of a rectangular shape shows an indoor unit. For example, by performing swing interlocking control as shown in FIG. 24 and FIG. 25, even if it is a two-way blowing type or one-direction blowing type indoor unit, a longitudinal circulation air flow can be generated, and the entire indoor space can be efficiently stirred. can do.

(7)
In the air conditioner 1 in the above embodiment, the swing interlocking control in summer and winter is performed without distinction. However, the present invention is not limited to this, and as shown in FIGS. 26 and 27, the swing interlocking control is performed in summer and winter. The control may be performed separately. In FIGS. 26 and 27, the square shape indicates the indoor unit.

  In summer, the window side becomes hot, and hot air rises on the window side due to heat flowing in from the window. For this reason, in the summer season, a vertical circulation air flow that suppresses the rise of hot air is generated by making the direction of the flap close to the window side (see FIG. 26). Accordingly, the indoor space can be agitated by pushing down the high-temperature air generated on the window side by the low-temperature air from the indoor unit.

  Contrary to summer, in the winter, the window side gets cold and heat escapes from the window, so low-temperature air tends to accumulate on the window side. For this reason, in the winter season, a vertical circulation airflow is generated such that a warm airflow flowing near the floor is directed to the window side with the flap positioned downward inside the room (see FIG. 27). Thereby, the cool air accumulated near the floor on the window side can be pushed up, and the temperature unevenness in the indoor space can be eliminated.

  In addition, as shown in FIGS. 26 and 27, in the summer and winter seasons, the position of the flap may be fixed without switching the longitudinal circulation direction, or the swing may be performed periodically from the state shown in FIGS. You may let them. In this case, the determination of summer and winter may be set manually by the user using an input device such as a remote controller, or may be determined automatically from the relationship between the outside air temperature and room temperature. In the case of automatic determination, for example, the case where the temperature obtained by subtracting the room temperature from the outside temperature exceeds A ° C is determined as summer, and the case where the temperature obtained by subtracting the outside temperature from the room temperature exceeds B ° C is determined as winter. Is determined. In this case, optimum values may be set in advance for A and B, or may be set later by the user. In this case, the outside temperature is detected by an outside temperature sensor installed in the outdoor unit.

(8)
In the air conditioning apparatus 1 according to the above embodiment, the swing pattern control is executed with seven swing patterns according to the seven phases, but is not limited to the seven phases. Also good. Moreover, after setting the pattern 7 to be performed when there is temperature unevenness in the heating stable period, a pattern in which the lower blowing period is set longer is added as the heating stable period (no temperature unevenness) to obtain eight patterns. good. In addition, the pattern added in the latter case is a pattern in which the horizontal blowing and the bottom blowing of the pattern 3 are reversed.

  The control device according to the present invention has an effect that indoor comfort can be improved, and air that can change the direction of the wind supplied from the air outlet by controlling the flaps arranged in the air outlet. It is useful as a control device for a harmony device.
