JP 2010-32062 A

  However, the blade member additionally installed as an optional component as in Patent Document 1 is only installed on the panel main body at a position where the louvered air is blocked, and cannot be controlled from the indoor unit like the louver. . In addition, there is a problem that the function of adjusting the blowing direction by the louver is not utilized and the comfort is impaired.

  The present invention has been made in view of such circumstances, and is compatible with both wind direction control by a louver and suppression of draft feeling, and a control device that can maintain comfort, and an air conditioning system including the same, An object of the present invention is to provide a control method.

In order to solve the above problems, the present invention employs the following means.
The present invention provides an air-conditioning air outlet that opens downward in the panel body, a louver that is pivotally provided in the air outlet and adjusts the direction of air-conditioning air, and the air outlet of the panel body. An air wing that is disposed outside the mouth and is rotatable between a storage position that is flush with the panel body and a louver direction position that faces the conditioned air blown from the blowout opening. And a control device for an air conditioner that rotates the air wing between the two positions, and intercepts the position information of the louver and the conditioned air blown from the position of the louver. A storage unit that stores correspondence information that associates the position information of the air wing, and the position of the air wing that corresponds to the current position of the louver is determined based on the correspondence information. To provide a control apparatus and a control means for moving said air wing position.

According to the configuration of the present invention, the storage position that is flush with the panel body on the outside of the blowout opening that opens downward in the panel body, and the louver direction position that faces the conditioned air blown from the blowout opening, An air wing that can be freely rotated is disposed, and the air wing can be freely rotated between a storage position and a louver direction position by a rotation mechanism. Based on the correspondence information in which the louver position information and the air wing position information are associated with each other, the air wing position corresponding to the current louver position is determined, and the air wing position is determined to be the determined air wing position. The wing is rotated and moved.
Depending on the louver position, the conditioned air blown out from the outlet may directly hit a person who is in the lower part, but according to the present invention, the air wing is located at a position determined according to the position of the louver. It can be controlled to block the flow of conditioned air and reduce the draft feeling.

  In the correspondence information of the control device, the louver position information and the air wing position information may be associated with each outlet.

  Since the louver position information and the air wing position information are associated with each outlet, the validity of the air wing or the position setting of the air wing can be switched for each outlet, and the operation according to the user's wishes. Can be made.

  The correspondence information of the control device may be associated with positional information of the louver and positional information of the air wing according to an operation mode of the air conditioner.

  Since the correspondence between the louver position information and the air wing position information is made according to the operation mode (for example, heating, cooling, dehumidification, air blowing, etc.), it corresponds to the validity of the air wing or the position of the louver. The position of the air wing can be set for each operation mode, and the operation according to the user's wish can be performed.

  The correspondence information of the control device holds, as reference information, position information of the air wing corresponding to position information of the louver in a specific operation mode among a plurality of operation modes of the air conditioner, and the control The means may correct the position of the air wing determined based on the reference information in accordance with the operating state of the air conditioner.

By using the position information of the air wing with respect to the louver position information of a specific operation mode as a reference, the control of the air wing becomes easy.
For example, the specific operation mode is “fan”. In the case of ventilation, the conditioned air that is blown out is equal to the ambient temperature, so that air conditioned air that has a temperature difference from the ambient temperature (for example, cold conditioned air due to cooling or dehumidifying operation or warm conditioned air due to heating operation) The blown-out conditioned air does not move upward or move downward.

  The control means of the control device may move the air wing to a position below a predetermined angle from the reference information when the specific operation mode is air blowing and the operation mode is cooling or dehumidification. .

  In the case of cooling or dehumidification, the blowing temperature is lower than the ambient temperature, and the conditioned air blown out flows below the air blowing, so moving the air wing downward from the reference can prevent draft feeling it can.

  The control means of the control device may move the air wing to a position above the reference information by a predetermined angle when the specific operation mode is air blowing and the operation mode is heating.

  In the case of heating, since the blowout temperature is higher than the ambient temperature, the conditioned air blown out flows above the reference air flow, so the air wing is moved above the reference to prevent a draft feeling Can do.

  In the above control device, when the temperature of the conditioned air blown from the outlet is equal to or higher than a first predetermined value, the control means moves the air wing to a position above the reference information by a predetermined angle. You may let them.

  When the blowing temperature of the conditioned air is higher than the ambient temperature, the blown conditioned air flows to the upper side than during blowing. Therefore, the draft feeling can be prevented by moving the air wing upward.

  In the above control device, when the temperature of the conditioned air blown from the outlet is equal to or lower than a second predetermined value, the control means moves the air wing to a position below the reference information by a predetermined angle. Also good.

  When the blowing temperature of the conditioned air is lower than the ambient temperature, the blown conditioned air flows downward than during blowing. Therefore, the draft feeling can be prevented by moving the air wing downward.

  In the above control device, a temperature difference between the blowing temperature of the conditioned air blown from the blowing port and the ambient temperature of the indoor unit is a third predetermined value or more, the specific operation mode is air blowing, and the operation mode When is a cooling, the control means may move the air wing to a position below the reference information by a predetermined angle.

  Since the blowing temperature is lower than the ambient temperature, the blown air-conditioning air flows downward as compared with the time of blowing. Therefore, the draft feeling can be prevented by moving the air wing downward.

  In the control device, a temperature difference between the blowout temperature of the conditioned air blown from the blowout opening and the ambient temperature of the indoor unit is a third predetermined value or more, the specific operation mode is blown air, and the operation When the mode is heating, the control unit may move the air wing to a position that is a predetermined angle above the reference information.

  Since the blow-out temperature is higher than the ambient temperature, the blown-out conditioned air flows to the upper side than during blowing. Therefore, the draft feeling can be prevented by moving the air wing upward.

  In the control device, when the air volume is equal to or less than a fourth predetermined value, the specific operation mode is air blowing, and the operation mode is cooling, the control means sets the air wing to be more predetermined than the reference information. It may be moved to a position below the angle.

  When the air volume is small, the air speed of the air-conditioning wind blown is small, the influence of buoyancy due to the temperature difference between the ambient temperature and the blowing temperature increases, and the wind direction tends to change. Therefore, the draft feeling can be prevented by moving the air wing downward in consideration of the fact that the conditioned air blown out tends to be more downward when the air flow is small and in the cooling operation.

  In the control device, when the air volume is equal to or less than a fourth predetermined value, the specific operation mode is air blowing, and the operation mode is heating, the control means sets the air wing to be more predetermined than the reference information. It may be moved to a position above the angle.

  When the air volume is small, the air speed of the air-conditioning wind blown is small, the influence of buoyancy due to the temperature difference between the ambient temperature and the blowing temperature increases, and the wind direction tends to change. Therefore, the draft feeling can be prevented by moving the air wing upward in consideration of the fact that the air flow is small and the conditioned air blown out tends to be more upward in the heating operation.

  In the control device, when the swing setting is such that the louver swings, the control means has a speed slower than the rotation speed of the louver when the swing setting is not set, and the louver and the louver The air wing may be swung.

  The air wing does not catch up with the louver and prevents the air conditioned air from the louver from leaking without being blocked by the air wing.

  In the control device, when the air wing is valid, the movable range of the louver is made narrower than the movable range of the louver when the air wing is invalid, and the louver is movable. The lower angle range of the range may be omitted.

  Thereby, while preventing a draft feeling, the short circuit which sucks in the blown-out conditioned air from a suction inlet can be prevented.

  In the control device, when it is detected that the air wing is valid and the suction temperature in the thermo-on state and the thermo-off state is greater than or equal to a predetermined thermo-on off suction temperature difference, the control means includes: The louver or the air wing may be moved until the suction temperature in the thermo-on state and the thermo-off state is lower than a predetermined thermo-on off suction temperature.

  Thereby, a short circuit can be prevented.

A heat exchanger 5 that is molded, a drain pan 6 disposed in the lower part of the heat exchanger 5, a blowout air passage 7 formed between the peripheral wall of the drain pan 6 and the inner peripheral surface of the unit body 2, The configuration includes a bell mouth 8 and the like arranged on the suction side of the turbo fan 4. The air conditioner 1 is connected to the outdoor unit via two refrigerant pipes 9 including a liquid pipe and a gas pipe and an electric wiring 10.

  The panel body 3, which is also called a ceiling panel or a decorative panel installed so as to cover the lower surface of the unit body 2, is a panel having a substantially square shape, and has an opening (suction port) for sucking indoor air into the central portion. ) 11, and a suction grill 12 is installed in the suction port 11. The suction grill 12 is provided with an air filter (not shown) on the inner surface side of the grill. In order to replace or clean the air filter, the suction filter 12 is connected to the panel body 3 via a wire 13, a lifting motor not shown. It is installed so that it can be moved up and down so that it can be lowered to the floor of the room. In addition, in order to clean an air filter automatically, it is good also as a structure incorporating an air filter automatic cleaning mechanism.

  Further, the panel body 3 is provided with outlets 14 in four directions corresponding to the four sides of the panel body 3 so as to surround the room air inlet 11, and heat is supplied from each outlet 14. Air cooled or heated by the exchanger 5 is blown out indoors as conditioned air. A louver 15 for adjusting the blowing direction (wind direction) of the conditioned air is rotatably installed at each of the four blowing outlets 14 and is individually independent via an actuator (motor) (not shown). To be rotated.

Further, as shown in FIGS. 2 and 3, the panel body 3 is disposed outside the outlets 14, and is disposed outside the outlets 14 and is flush with the panel body 3 (position in FIG. 2). An air wing 17 is provided that is rotatable between the conditioned air blown from the opening 14 and a louver direction position (position in FIG. 3) facing the conditioned air. The air wing 17 is a flat member that changes the direction of air flow by blocking the air-conditioning air by projecting to a position in the louver direction facing the air outlet 14, and the air-conditioning air blown from each air outlet 14 is directly directed to a person who is below. This is to reduce or eliminate the draft feeling caused by hitting.
Further, as shown in FIGS. 2 and 3, the panel main body 3 is provided with a human sensor 30. The human sensor 30 detects the presence or position of a person in the target area and outputs a detection signal to the control device 50.

  The air wing 17 protrudes to a position facing the conditioned air blown in the louver direction from each outlet 14 and blocks the conditioned air, and arm portions integrally provided at both ends of the wing portion 18. 19 and a gate shape. The air wing 17 is supported so that the base end portion of the arm portion 19 is rotatable with respect to the panel main body 3 via a support shaft (not shown) and is flush with the panel main body 3 (position in FIG. 2). ) And the louver direction position (position in FIG. 3) facing the conditioned air blown from the blowout port 14. Hereinafter, a specific configuration of the air wing 17 will be described in detail with reference to FIGS. 4 to 7.

  The wing part 18 and the arm part 19 of the air wing 17 form a part of the panel main body 3, and when rotated to the storage position shown in FIG. It is designed to be flush with the front surface (lower surface). The wing portion 18 is a resin-made flat plate member having a length equal to that of the blowout port 14 and disposed along the outside thereof and having a certain width dimension that forms a part of each side of the panel body 3. There is a gate shape in which an arm portion 19 narrower than the wing portion 18 is integrally formed at both ends thereof. On the back side of the wing portion 18 and both arm portions 19, ribs are integrally formed so as to ensure the strength and rigidity of each.

Further, a support shaft that supports the air wing 17 so as to be rotatable with respect to the panel body 3 is integrally provided at the base end portion of both the arm portions 19. Further, the base end side of the wing portion 18 is rotatably supported on the inner end edge side of the wing portion 18, and when the air wing 17 is rotated to the storage position, the outer end side is along the back surface of the wing portion 18. When the air wing 17 is turned to the louver direction position when it is in the storage position (see FIG. 4), the outer end is self-supporting upward and turns to a position that blocks the conditioned air (see FIGS. 5 and 7). A wing 21 is provided.
When the remote control is turned on, the rotation position of the actuator that rotates the louver 15 is detected, and the air wing 17 is rotated to a louver direction position corresponding to the position.

  For example, as shown in FIG. 5, when the louver 15 is in the horizontal blowing position, the air wing 17 is rotated to the louver direction position corresponding to that position, and the self-supporting sub wing 21 is moved in the louver direction. The draft feeling is reduced by changing the flow of the conditioned air. Further, as shown in FIG. 7, when the louver 15 is in the downward blowing position, the air wing 17 is rotated to the louver direction position corresponding to the position, and the independent sub wing 21 is air-conditioned in the louver direction. The draft feeling can be reduced or eliminated by blocking and changing the wind flow.

  Further, in particular, when the draft feeling due to the conditioned air is not felt or when it is desired to positively obtain the draft feeling, the air wing 17 may be moved to a position where the conditioned air blown from the louver 15 is not blocked. As shown in FIG. 6, the air wing 17 may be closed to a storage position that is flush with the panel body 3, and only the louver 15 may be used.

  The control device 50 incorporates, for example, a microcomputer and controls the refrigeration cycle based on data from various sensors and controllers provided in the outdoor unit. In addition, a series of processes for realizing various functions to be described later are recorded in a recording medium or the like in the form of a program, and the CPU reads the program into a RAM or the like to execute information processing / arithmetic processing. By doing so, various functions described later are realized.

Specifically, as shown in FIG. 8, the control device 50 includes a storage unit (storage unit) 51 and a control unit (control unit) 52.
The storage unit 51 stores correspondence information that associates the position information of the louver 15 with the position information of the air wing 17 that blocks the conditioned air blown from the position of the louver 15. Correspondence information is set in association with position information of the louver 15 and the air wing 17 according to various conditions such as operation mode, blowout temperature, temperature difference between the suction and blowout temperatures, and air volume (details will be described later). To do).

  The control device 50 includes an I / O connector or the like for connecting to an external device, and inputs correspondence information from the outside via the I / O connector and stores it in the storage unit 51 in advance. Alternatively, the present invention is not limited to this, and the user may newly create correspondence information via the remote control by the user operating the remote control, or the correspondence information stored in the storage unit 51 may be read out by the user. Appropriate changes may be made to the correspondence information read by remote control operation.

  The control unit 52 determines the position of the air wing 17 corresponding to the current position of the louver 15 based on the correspondence information, and moves the air wing 17 to the determined position. Specifically, the control unit 52 moves the air wing 17 to a position where the conditioned air blown out from the louver 15 is blocked (see, for example, FIGS. 5 and 7), and controls the air conditioner 1. And control for moving the air wing 17 to a position where the conditioned air blown from the louver 15 is not blocked in accordance with the operation state (see, for example, FIG. 6). In FIG. 6, as an example of invalidation, the air wing 17 is in a storage position where it is flush with the panel body 3 (that is, the air wing is fully closed), but the invalidation of the air wing 17 is limited to this. It is not necessary to move to a position where the conditioned air blown from the louver 15 is not blocked.

Further, the control unit 52 determines whether or not there is a person based on the detection signal acquired from the human sensor 30, and if it is determined that there is a person, the air wing 17 is maintained at the current setting. When it is determined that there is no person, the air wing 17 may be moved to a position that does not block the conditioned air blown from the louver 15 and invalidated. Alternatively, when the direction in which the person is present is detected, the control unit 52 may invalidate the air wings 17 other than the direction in which the person is present among the plurality of outlets 14.
When no person is detected, it is not necessary to consider the draft feeling. Therefore, the air wing is invalidated by moving it to a position where the conditioned air is not blocked, thereby preventing unnecessary operations. In addition, since air circulation in the room is improved, it is possible to operate efficiently.
The trigger for controlling the air wing 17 by the control unit 52 in the present embodiment will be described as a case where a command is acquired at a user-desired timing via a remote controller.

Hereinafter, an example of correspondence information stored in the storage unit 51 will be described.
For example, in the correspondence information, the position information of the louver 15 and the position information of the air wing 17 are associated with each outlet 14. The association between the position information of the louver 15 and the position information of the air wing 17 is set for each outlet 14, so that the validity of the air wing 17 is switched for each outlet 14. Thereby, when the several outlet 14 is provided with respect to one air conditioning apparatus 1, compared with the case where the positional information on the same air wing 17 is uniformly set with respect to the several outlet 14, It is possible to make the operation more in line with the wishes of the respective users below the outlets 14.

  In the correspondence information of another example, the position information of the louver 15 and the position information of the air wing 17 may be associated with each other according to the operation mode of the air conditioner 1. The operation mode is, for example, heating, cooling, dehumidification, air blowing, or the like. Thus, for example, the air wing 17 can be switched between valid and invalid according to the operation mode, such as invalidating the air wing 17 during heating and validating the air wing 17 during cooling.

Below, the effect | action of the air conditioning system 100 which concerns on this embodiment is demonstrated.
During operation of the air conditioner 1, room air is sucked into the unit body 2 from the suction port 11 of the panel body 3 through the suction grill 12 and the bell mouth 8 by the rotation of the turbofan 4. The air blown in the centrifugal direction from the turbo fan 4 in the unit main body 2 is heat-exchanged with the refrigerant in the process of passing through the heat exchanger 5 arranged around the turbo fan 4, and cooled or heated to control the temperature. Then, the air is blown into the room from the air outlets 14 provided in the four directions of the blowout air passage 7 and the panel body 3, and is used for indoor air conditioning.

The conditioned air blown into the room from the blowout port 14 of the panel body 3 is adjusted in the blowout direction by changing the angle of the louver 15 provided in the blowout port 14. Since the angle of the louver 15 can be changed individually for each outlet 14 by a remote controller via an actuator, the user arbitrarily sets the angle and adjusts the outlet direction.
When the conditioned air set by adjusting the louver 15 gives discomfort to the user underneath, the user inputs a command to activate the air wing 17 via the remote controller.

Corresponding information is read out and referred to based on the input activation command of the air wing 17. Based on the correspondence information, the position information of the air wing 17 corresponding to the current position of the louver 15 set according to the operation mode and the outlet 14 is read out. The air wing 17 is controlled so as to coincide with the read position information of the air wing 17.
By controlling the air wing 17, the air wing 17 is pushed out to a position in the louver direction opposite to the conditioned air blown from the air outlet 14, and is changed so as to block the flow of the conditioned air in the louver direction. Thus, the draft feeling is reduced.
In addition, when a person under the outlet 14 actively wants to obtain a draft feeling, the user inputs a command to invalidate the air wing 17 via the remote controller, whereby the conditioned air blown from the louver 15 is input. The air wing 17 may be moved to a position that does not block the air.

  As described above, according to the control device 50 according to the present embodiment, the air conditioning system 100 including the control device 50, and the control method, the panel is provided outside the blowout port 14 opened downward in the panel body 3. An air wing 17 that is rotatable between a storage position that is flush with the main body 3 and a louver direction position that opposes the conditioned air blown from the air outlet 14 is disposed. Is rotatable between two positions, a storage position and a louver direction position. The position of the air wing 17 corresponding to the current position of the louver 15 is determined based on the correspondence information in which the position information of the louver 15 and the position information of the air wing 17 are associated with each other, and the determined position of the air wing 17 is determined. The air wing 17 is rotated and moved so that

Depending on the position of the louver 15, the conditioned air blown from the outlet 14 depending on the position of the louver may give a draft feeling by directly hitting a person located below. The air wing 17 is controlled to block the flow of the conditioned air, and the draft feeling can be reduced.
In addition, when the position information of the louver 15 and the position information of the air wing 17 are associated with each outlet 14, the validity of the air wing 17 can be switched for each outlet 14, and the user's desire It is possible to move along.
In addition, when the position information of the louver 15 and the position information of the air wing 17 are associated according to the operation mode (for example, heating, cooling, dehumidification, air blowing, etc.), the validity of the air wing 17 is disabled. It can be set for each operation mode, and can be operated more in line with the user's wishes.

[Modification 1]
The louver 15 may be selected to have a swing setting that swings at a predetermined interval in a section of a movable range (for example, a fully closed state to a fully open state). When the air wing 17 is used, the louver 15 swings the air wing 17 at a movement speed that is slower than the movement speed of the swing when not in use. The air wing 17 is swung with the swing of the louver 15.
As described above, when the air wing 17 is used and the louver 15 is set to swing, the swing speed of the louver 15 is slower than the speed when the air wing 17 is unused and the louver 15 is swung alone. Let As a result, the movement of the air wing 17 does not catch up with the louver 15, and the conditioned air from the louver 15 leaks without being blocked by the air wing 17, preventing the situation where the conditioned air cannot be blocked, thereby reliably preventing the draft feeling.

[Modification 2]
When the air wing 17 is activated, a setting for prohibiting selection of the swing setting of the louver 15 may be performed. Thereby, downward conditioned air can be reliably prevented.

[Modification 3]
The louver 15 has a movable range (for example, the fully closed state in FIG. 4 to the fully opened state in FIG. 7), and when the air wing 17 is invalidated, the movable range is the full movable range. The movable range when the is activated is limited to a narrower range than the movable range when the air wing 17 is deactivated. Specifically, the movable range of the louver 15 is limited so that the louver 15 cannot move to an angle within a predetermined range from the fully open state where the direction in which the conditioned air blows out from the louver 15 is downward (that is, the louver movable range). Is limited to the movable range in the upward direction compared to the case where the air wing is disabled).
Thereby, while preventing a draft feeling, the short circuit which sucks in the conditioned air blown from the blower outlet 14 as ambient air from the suction inlet 11 can be prevented.

[Second Embodiment]
Hereinafter, a second embodiment of the present invention will be described. This embodiment differs from the first embodiment in that the air wing is controlled according to the operating state of the air conditioning system. About the air conditioning system of this embodiment, description is abbreviate | omitted about the point which is common in 1st Embodiment, and a different point is mainly demonstrated using FIGS.

  The correspondence information stored in the storage unit 51 associates the position information of the louver 15 and the position information of the air wing 17 with each other according to the operation mode (cooling, heating, dehumidification, ventilation, etc.). Specifically, the correspondence information uses, as reference information, the position information of the air wing 17 corresponding to the position information of the louver 15 in a specific operation mode (for example, air blowing) among the plurality of operation modes of the air conditioner 1. The position information of the air wing 17 with respect to the position information of the louver 15 in the operation mode (for example, cooling, heating, dehumidification, etc.) other than the specific operation mode that is held has a correction value from the reference information.

For example, in the case of cooling / dehumidification, the correction value is set to “move to a lower position by a predetermined angle (eg, 3 °) from the time of blowing”. In the case of heating, the setting is “move to a position on the upper side by a predetermined angle (eg, 3 °) from the time of blowing”.
In the case of cooling / dehumidification, since the blowing temperature from the air conditioner 1 is lower than the ambient temperature, the blown conditioned air moves to the lower side than during blowing. Therefore, the air wing 17 is also moved downward. On the other hand, in the case of heating, since the blowing temperature is higher than the ambient temperature, the blown conditioned air moves to the upper side than during blowing. Therefore, the air wing 17 is also moved upward.
In the air blowing operation, since the conditioned air blown out is equal to the ambient temperature, the conditioned air blown out like the conditioned air with a temperature difference from the ambient temperature does not move upward or downward, The position information of the air wing 17 relative to the position information of the louver at the time of blowing is used as a reference.

The control unit 52 reads the position information of the air wing 17 corresponding to the current louver 15 determined based on the reference information of the correspondence information, and based on the read position information of the air wing 17 and the correction value, The wing 17 is controlled.
The trigger for controlling the air wing 17 by the control unit 52 may be a case where a valid / invalid command is acquired by the user, or when the operation of the air conditioner 1 is started or when the operation mode is switched. It may be. In addition, the trigger for controlling the air wing 17 by the control unit 52 may be an air outlet temperature, a louver position, a set temperature, human detection by the human sensor 30, and the like.

Below, the effect | action of the air conditioning system 100 which concerns on this embodiment is demonstrated. Here, a case where the heating operation is started and then switched to the air blowing operation will be described as an example, but the order of the operation switching is not limited thereto.
When the heating operation of the air conditioner 1 is started, the correspondence information is referred to, and the position information of the air wing 17 corresponding to the current louver position in the heating operation is read out. Since the position information of the air wing 17 in the heating operation is set with a correction value “moving the angle 3 ° upward from the reference information at the time of blowing”, the position of the air wing 17 set as the reference information While reading the information, the air wing 17 is controlled to a position where the angle of 3 ° is moved upward with respect to the position information.

  Thereafter, when the operation of the air conditioner 1 is switched to the air blowing operation, the correspondence information is referred to, and the position information of the air wing 17 corresponding to the current louver position in the air blowing operation, that is, the reference information is read out. The air wing 17 is controlled to be at the position of the reference information.

As described above, according to the control device 50 according to the present embodiment, the air conditioning system 100 including the control device 50, and the control method, in the blowing operation, the conditioned air blown out is equal to the ambient temperature. Air-conditioning air blown out, such as air-conditioning air that has a temperature difference from the temperature (for example, cold air-conditioning air due to cooling or dehumidifying operation or warm air-conditioning air due to heating operation) must move upward or downward. There is no standard.
In the case of cooling or dehumidification, the blowing temperature is lower than the ambient temperature, and the conditioned air blown out flows below the air blowing, so the air wing is moved downward from the reference to reliably prevent draft feeling be able to.
In the case of heating, since the blowout temperature is higher than the ambient temperature, the conditioned air blown out flows above the reference air flow, so moving the air wing upward from the reference ensures a draft feeling. Can be prevented.

[Third Embodiment]
Hereinafter, a third embodiment of the present invention will be described. In this embodiment, it differs from 1st Embodiment and 2nd Embodiment by the point which controls an air wing according to the temperature conditions of the conditioned air blown from the blower outlet of the air conditioning apparatus 1. FIG. About the air conditioning system of this embodiment, description is abbreviate | omitted about the point which is common in 1st Embodiment, 2nd Embodiment, and a different point is mainly demonstrated using FIGS.

The air conditioner is provided with a temperature sensor (not shown), and the detection result detected by the temperature sensor is output to the control device 50. For example, the temperature sensor detects a blowing temperature blown from the blowing port 14.
Corresponding information stored in the storage unit 51 includes position information of the louver 15 and position information of the air wing 17, and the air wing 17 according to the temperature of the conditioned air blown from the air outlet 14. Are associated with each other.

  For example, the correspondence information used in the heating operation is set according to the case where the blowing temperature is equal to or higher than a first predetermined temperature (for example, 35 ° C.) and the case where the temperature is lower than the first predetermined temperature. In the heating operation, when the blowing temperature is equal to or higher than the first predetermined temperature, the correction value of the position information of the air wing 17 corresponding to the position information of the louver 15 is set to “move the air wing 17 upward by a predetermined angle”. When the blowout temperature is lower than the first predetermined temperature, the correction value of the position information of the air wing 17 corresponding to the position information of the louver 15 is set to “none” (that is, not corrected). .

  This is because when the air-conditioning air blowing temperature is higher than the ambient temperature, the air-conditioning air that has been blown flows upward from the air blowing time, and the air wing is moved upward to prevent a draft feeling. be able to.

The correspondence information used in the cooling operation is set according to the case where the blowing temperature is equal to or lower than the second predetermined temperature (for example, 15 ° C.) and the case where it is higher than the second predetermined temperature. In the cooling operation, when the blowing temperature is equal to or lower than the second predetermined temperature, the correction value of the position information of the air wing 17 corresponding to the position information of the louver 15 is “move the air wing 17 downward by a predetermined angle”. Is set, and the correction value of the position information of the air wing 17 corresponding to the position information of the louver 15 is set to “none” (that is, not corrected). ing.
This is because when the air-conditioning air blowing temperature is lower than the ambient temperature, the air-conditioning air that is blown out flows below the air blowing, and the air wing is moved downward to provide a draft feeling. Can be prevented.

  The control unit 52 reads the position information and correction value of the air wing 17 corresponding to the current louver 15 determined based on the correspondence information, and sets the position in consideration of the read position information and correction value of the air wing 17. The air wing 17 is controlled.

  As described above, according to the control device 50 according to the present embodiment, the air conditioning system 100 including the control device 50, and the control method, when the blowing temperature of the conditioned air is higher than the ambient temperature, the blowing is performed. Air conditioned air flows upward from the time of air blowing. Therefore, the draft feeling can be prevented by moving the air wing upward. In addition, when the blowing temperature of the conditioned air is lower than the ambient temperature, the blown conditioned air flows downward than during blowing. Therefore, the draft feeling can be prevented by moving the air wing downward.

  In addition, in this embodiment, although demonstrated as detecting blowing temperature with a temperature sensor, the detection method of blowing temperature is not limited to this. For example, the blowing temperature may be determined to be greater than or equal to a predetermined temperature based on an indoor heat exchanger temperature sensor, the condensation / evaporation pressure of the indoor unit, the rotational speed of the compressor, and the like.

[Fourth Embodiment]
The fourth embodiment of the present invention will be described below. In this embodiment, it differs from 1st Embodiment, 2nd Embodiment, and 3rd Embodiment by the point which controls an air wing according to the temperature conditions of the conditioned air blown from the blower outlet of the air conditioning apparatus 1. FIG. About the air conditioning system of this embodiment, description is abbreviate | omitted about the point which is common in 1st Embodiment, 2nd Embodiment, and 3rd Embodiment, and a different point is mainly demonstrated using FIGS.

  The air conditioner 1 is provided with a blowout temperature sensor and a suction temperature sensor (not shown), and the detection results detected by the blowout temperature sensor and the suction temperature sensor are output to the control device 50. For example, the blowout temperature sensor detects the blowout temperature of the conditioned air blown in the vicinity of the blowout opening 14, and the suction temperature sensor detects the ambient temperature of the indoor unit of the air conditioner 1 in the vicinity of the suction opening 11.

  Corresponding information stored in the storage unit 51 includes the position information of the louver 15 and the position information of the air wing 17, and the temperature between the ambient temperature and the blowing temperature of the conditioned air blown from the blowing port 14. The correction value of the air wing 17 is associated according to the difference. In the present embodiment, the correspondence information uses the specific operation mode of the air conditioner 1 as the air flow, and holds the position information of the air wing 17 relative to the position information of the louver 15 in the case of the air blowing as the reference information.

  For example, the correspondence information during the cooling operation is that the temperature difference between the ambient temperature and the blowing temperature is equal to or greater than a first predetermined temperature difference (third predetermined value) (for example, 10 ° C.) (that is, the ambient temperature is higher than the blowing temperature). If the difference is less than the first predetermined temperature difference, the correction value of “moving the air wing 17 downward by a predetermined angle” is set, and if the difference is less than the first predetermined temperature difference, the air wing 17 corresponding to the position information of the louver 15 is set. The correction value of the position information is “none” and is the position of the reference information. This is set so that the air wing 17 is also moved downward in consideration of the fact that the blown air temperature is lower than the ambient temperature, and the blown conditioned air is directed downward than during blowing.

  Further, the correspondence information during the heating operation indicates that if the temperature difference between the ambient temperature and the blowing temperature is equal to or greater than the first predetermined temperature difference (that is, the ambient temperature is lower than the blowing temperature), “the air wing 17 is set at a predetermined angle. When the correction value “move upward” is set and the difference is less than the first predetermined temperature difference, the correction value of the position information of the air wing 17 corresponding to the position information of the louver 15 is set to “none”, and the reference information The position of This is set so that the air wing 17 is also moved upward in consideration of the fact that the blown air temperature is higher than the ambient temperature, and the blown conditioned air is directed upward than during blowing.

  The control unit 52 reads the position information and correction value of the air wing 17 corresponding to the current louver 15 determined based on the correspondence information, and sets the position in consideration of the read position information and correction value of the air wing 17. The air wing 17 is controlled.

As described above, according to the control device 50 according to the present embodiment, the air conditioning system 100 including the control device 50, and the control method, in the case of the cooling operation, the blowout temperature is lower than the ambient temperature. Considering the fact that the conditioned air that has blown out flows below the air blowing, if the temperature difference between the ambient temperature and the blowing temperature is greater than or equal to the first predetermined temperature difference, the air wing is moved downward to create a draft A feeling can be prevented.
Further, in the case of heating operation, since the blowing temperature is higher than the ambient temperature, the temperature difference between the ambient temperature and the blowing temperature is the first predetermined temperature in consideration of the fact that the blown conditioned air flows upward from the time of blowing. If the difference is greater than or equal to the difference, the draft feeling can be prevented by moving the air wing upward. In both the cooling operation and the heating operation, when the temperature difference is less than the first predetermined temperature difference, the temperature difference between the ambient temperature and the blowing temperature is small, so the air wing 17 is not corrected, and the reference position set at the time of blowing Leave as it is.

[Modification]
Comparing the suction temperature when the thermo is on and the suction temperature when the thermo is off, it is determined that a short circuit has occurred if the difference is greater than or equal to the specified thermo on / off suction temperature, and the difference between the suction temperature when the thermo is on and when the thermo is off The louver 15 or the air wing 17 may be moved until it becomes less than the thermo-on-off suction temperature difference.
Note that the comparison between when the thermo is on and when the thermo is off may be, for example, a comparison between when the compressor is operating and when it is stopped, and means a comparison when the air conditioning operation is performed and when the air conditioning operation is not performed.

[Fifth Embodiment]
The fifth embodiment of the present invention will be described below. The present embodiment differs from the first embodiment to the fourth embodiment in that the air wing is controlled in accordance with the air volume of the conditioned air blown from the air outlet of the air conditioner. About the air conditioning system of this embodiment, description is abbreviate | omitted about the point which is common in 1st Embodiment to 4th Embodiment, and a different point is mainly demonstrated using FIGS. 1-8.

As correspondence information stored in the storage unit 51, position information of the louver 15 and position information of the air wing 17 are set, and a correction value of the air wing 17 is associated with the amount of conditioned air. Further, in the present embodiment, the correspondence information uses the specific operation mode of the air conditioner 1 as air blowing, and holds the position information of the air wing 17 with respect to the position information of the louver 15 in the case of air blowing as reference information.
For example, when the airflow is equal to or less than the first predetermined airflow in the cooling operation, the correction value is set to “move the air wing 17 to a position on the lower side by a predetermined angle (for example, 2 °) from the time of blowing”. To do. Further, in the heating operation, when the air volume is equal to or less than the first predetermined air volume, a correction value of “moving the air wing 17 to a position on the upper side by a predetermined angle (for example, 2 °) from the time of blowing” is set.

The first predetermined air volume is set to “below or weak”, for example, when the air volume setting is set in five stages (for example, strongest, strong, medium, weak, and weakest).
When the air volume is small, the blown air speed becomes small, and when the blown air speed is slow, the conditioned air blown out as cooling becomes more downward, and the conditioned air blown out as heating becomes more upward. Moreover, when there is little air volume, the influence of the buoyancy by the temperature difference of ambient temperature and blowing temperature becomes large, and a wind direction becomes easy to change more. Considering this, a correction value is set when the air volume is equal to or less than the first predetermined air volume.

Further, in the cooling operation and the heating operation, when the air volume is larger than the first predetermined air volume, the air wing 17 is set as the position of the reference information. If the wind speed is high, the influence of buoyancy is small, so the position of the air wing 17 is not corrected.
The control unit 52 reads the position information and correction value of the air wing 17 corresponding to the current louver 15 determined based on the reference information of the correspondence information, and based on the read position information and correction value of the air wing 17. Then, the air wing 17 is controlled.

  As described above, according to the control device 50 according to the present embodiment, the air conditioning system 100 including the control device 50, and the control method, the position of the air wing 17 is determined according to the air volume of the conditioned air, Control. As a result, even if a change in the air volume occurs in the operation of the air conditioner 1, the position of the air wing 17 is corrected following the change in the air volume, so that the draft feeling can be prevented more reliably.

[Modification]
As another example, when the air volume is controlled below the second predetermined air volume by the control of the air conditioner 1, or the air volume set by the remote controller is set to a fixed value below the second predetermined air volume such as “weakest”, for example. When it is assumed that the air volume does not change and the draft feeling is not given in the operation of the air conditioner 1, the air wing 17 is moved to a position where the conditioned air is not blocked and invalidated. Unnecessary operations by 17 may be prevented.

[Sixth Embodiment]
The sixth embodiment of the present invention will be described below. This embodiment is different from the first to fifth embodiments in that the air wing is controlled according to the ambient humidity. About the air conditioning system of this embodiment, description is abbreviate | omitted about the point which is common in 1st Embodiment to 5th Embodiment, and a different point is mainly demonstrated.

The air conditioner includes a humidity sensor (not shown) that detects the humidity of the air blown into the indoor unit, and a temperature sensor (not shown) that detects the temperature of the intake air.
When the ambient humidity of the air-conditioning target area where the air conditioner is arranged is equal to or higher than a predetermined humidity, the air wing may be moved to a position where it does not block the conditioned air blown from the louver and invalidated.
Since the place where the cold air hits is likely to condense, the air wing is invalidated by moving the air wing to a position where the air wing is not obstructed in the case of air conditioning conditions where the air wing may be condensed. Thereby, condensation of the air wing is prevented.
Note that the dew condensation range is set in advance in the indoor unit of the air conditioner.

[Seventh Embodiment]
The seventh embodiment of the present invention will be described below. The present embodiment differs from the first to sixth embodiments in that the air wing is controlled according to the air conditioning load. About the air conditioning system of this embodiment, description is abbreviate | omitted about the point which is common in 1st Embodiment to 6th Embodiment, and a different point is mainly demonstrated.

  The air wing may be set to be invalidated by moving the air wing to a position that does not block the conditioned air blown from the louver within a predetermined period after the operation of the air conditioner. Thereby, in a predetermined period from the start of the operation of the air conditioner, the indoor air can be brought closer to the set temperature by prioritizing the indoor air conditioning over avoiding the user's draft feeling.

Alternatively, when the difference between the target set temperature set in the air conditioner and the suction temperature is equal to or greater than the second predetermined temperature difference and rapid cooling or rapid heating is required, the position does not block the conditioned air blown from the louver. Alternatively, the air wing may be moved to be invalidated. Thus, until the temperature in the room, which is the air conditioning target area, reaches the target set temperature, the air conditioning in the room can be prioritized over avoiding the user's draft feeling, and the room air can be brought closer to the set temperature.
Thus, when the air conditioning load set in the air conditioner is large, it is possible to prioritize indoor temperature control by disabling the air wing.

  As mentioned above, although embodiment of this invention was explained in full detail with reference to drawings, the concrete structure is not restricted to this embodiment, The design change etc. of the range which does not deviate from the summary of this invention are included. For example, the first embodiment and the second embodiment may be combined, or all the embodiments may be used in combination.
