Description

  The present invention relates to a system for performing air conditioning by blowing conditioned air into a space to be air conditioned by a plurality of air outlet devices.

  When air conditioning is performed on an indoor space such as an office space in a building, the air outlet that blows conditioned air into the indoor space subject to air conditioning is a ceiling that takes into account the ease of conditioned air reaching the indoor space. It is common to arrange | position to. And when performing air conditioning with respect to such a comparatively large indoor space, control of dampers, such as VAV provided in the system which connected an air conditioner and a plurality of outlets via a duct, A mechanism for adjusting the temperature of the indoor space to an appropriate temperature by adjusting the amount of air blown out is adopted. An example of such a conventional air conditioning system is disclosed in Japanese Patent Laid-Open No. 8-75231.

  In such a conventional air conditioning system, an air outlet device such as a multi-layer cone type or a pan type that is generally excellent in diffusibility of the conditioned air into the space is used for the air outlet of the ceiling. However, a system such as Japanese Utility Model Laid-Open No. 5-18944 has been proposed in order to meet the needs that cannot be handled by a system that employs only such an outlet device.

JP-A-8-75231 Japanese Utility Model Publication No. 5-18944

  In the air conditioning according to the conventional system as disclosed in Patent Document 1, it is common that the air outlet provided on the ceiling is in a state where the draft does not occur in the living area. In recent years, the difference between the indoor temperature and the outside air temperature obtained by air conditioning tends to be reduced from the viewpoint of energy consumption suppression. In such an air condition, when the outside air temperature is extremely high or low, a person can enter the indoor space from the outside and feel the cold feeling that comes in contact with the indoor air from the state accustomed to the outside air temperature. I often feel unsatisfactory in the sense of warmth.

  However, in a system that covers the entire room using a conventional air outlet that emphasizes diffusibility, in order to satisfy the feeling of cooling and warmth experienced by some people, Air conditioning could not be performed, and the air conditioning state of the entire indoor space had to be adjusted. Adjustment of the air-conditioning condition of the entire indoor space takes time to reach the indoor temperature expected by the user who wants to change the temperature. As a result, the temperature may be uncomfortable, and it is difficult to take an appropriate measure, and the amount of energy input to the air conditioning increases as the entire space is adjusted.

  On the other hand, conditioned air that reaches the user's vicinity intensively by using a blower outlet that can adjust the wind direction and that has excellent directivity of the blown airflow, such as a nozzle type or pan-carver type, for local air conditioning to the user. As a result, it becomes easier to cause a temperature change in the surrounding area of the user, and it is possible to expect more effective air conditioning for the user, such as shortening the time required to reach the temperature preferred by the user.

  And the system which improved the adaptability to the preference of each person's temperature using together such a strong directivity blower outlet and the blower outlet for temperature-controlling the whole indoor space uniformly is the said patent document. Conventionally, as shown in FIG. In such a conventional system, two types of air outlets are connected to an air supply system from an air conditioner that generates conditioned air. Of these, the user can appropriately utilize a highly directional air outlet. It is possible to efficiently change the bodily sensation.

  In such a conventional system, the amount of air blown from the air outlet is adjusted by VAV or the like corresponding to the set indoor temperature. Usually, an air conditioner that generates and sends conditioned air is controlled in conjunction with air volume adjustment in VAV or the like, so that an appropriate amount of conditioned air corresponding to the air volume blown out from the air outlet is obtained from the air conditioner. It is a mechanism to be sent.

  However, there are cases where the conditioned air is sent locally into the indoor space mainly through a highly directional air outlet, and when the conditioned air is sent into a wide range of the indoor space mainly through the air outlet that emphasizes diffusibility. Since the air volume itself of the conditioned air reaching the air temperature does not change in particular, the operating state of the air conditioner is almost the same as the conventional one even when the switching of the blowing state is introduced, and the energy related to the air conditioning is not suppressed.

  The present invention was made in order to solve the above-mentioned problems, and while using both a blowout and a local blowout for a wide area of the indoor space, and adjusting the blowout air volume to the indoor space according to the blowout state, An object of the present invention is to provide an air-conditioning system that can save energy by reducing the amount of conditioned air supplied to a user without reducing the effect of air-conditioning on users in the indoor space.

  An air conditioning system according to the present invention has an opening facing an indoor space subject to air conditioning and is disposed on a ceiling of the indoor space, and blows supplied conditioned air to the indoor space from the opening. In an air conditioning system including a plurality of outlet devices, one or more are arranged on the ceiling as a substantially box-like body, connected to each of the outlet devices via a duct, and adjusts the amount of conditioned air flowing toward each outlet device And an air volume control unit that causes the air volume adjustment unit to adjust the air volume of conditioned air based on at least the temperature state of the indoor space, and the air outlet device includes an air passage on the inside. One or a plurality of local blowing portions that are arranged so as to be capable of adjusting the direction, flow conditioned air into the air passage, and guide and blow the conditioned air in the air passage extending direction; One or more in a predetermined arrangement It has a solid substantially plate-like guide body, and is arranged on each side of the local blow-out section. The conditioned air is advanced along each guide body, and the conditioned air is blown into the air-conditioning target space in a diffused state. A plurality of diffused blow-out sections, a state in which conditioned air is directed toward the local blow-out section and the conditioned air is mainly blown out through the local blow-out section, and a conditioned air is directed mainly through the local blow-out section and the conditioned air is mainly diffused out. And a control unit that controls switching of a state in which the conditioned air is blown out in the switching mechanism unit, and a control unit of a predetermined outlet device harmonizes with the switching mechanism unit. When the air blowing state is switched, information related to the switching is sent to the air volume control unit, and when the air volume control unit receives information from the control unit, the air volume adjusting unit goes to the predetermined air outlet device. About conditioned air It is intended to perform air volume adjustment to respond.

  Thus, according to this invention, it has a local blowing part and a diffusion blowing part as a blower outlet, and mainly blows out conditioned air locally from the local blowing part to a desired position in the indoor space. In addition to the normal adjustment that matches the air volume of the conditioned air that is blown out to the room temperature, it is possible to select the state in which the air flow of the conditioned air is widely diffused from the diffusion blowing part into the indoor space. In a state where the conditioned air is blown over a wide range from the diffusion blow-out part of the blow-out device, and the conditioned air can be diffused reliably in a wide area of the indoor space. While appropriately switching the state of blowing locally from the blowing part toward a specific narrow area where the user is present, the air flow varies depending on each blowing state, and the air volume is suitable for the user's ease of experiencing the air-conditioning effect. Adjust and adjust Air can be blown out, ensuring a comfortable feeling based on air conditioning for users of indoor spaces, while reducing the chances of conditioned air feeding with large air volume that uniformly changes the entire indoor space, efficiently Air conditioning can be performed and the cost of air conditioning can be reduced.

  Moreover, the air conditioning system which concerns on this invention shows that the said air volume control part switched the switching mechanism part so that it might be in the state which blows out conditioned air mainly through a local blowing part as needed. When the information from the control unit is received, the air volume adjusting unit is caused to adjust the air volume to a predetermined air volume that is set in advance by reducing the air volume of the conditioned air toward the air outlet device.

  As described above, according to the present invention, when the switching mechanism unit is operated so that conditioned air is locally blown out from the local blow-out unit of the blow-out device to a predetermined range of the indoor space, the air volume control unit is operated as the air volume adjustment unit. By controlling the air volume of the conditioned air by operating the user, the user can experience the air flow of the conditioned air, and in the local blowout state where the air conditioning effect is given more conspicuously, the user is comfortable with the air conditioning The air volume can be reduced within a range where a feeling can be obtained, and the amount of conditioned air supplied can be suppressed, and energy consumption related to conditioned air supply can be suppressed while ensuring a user's comfort.

  In addition, the air conditioning system according to the present invention is used for an operation of receiving an input operation of a user in an indoor space and sending an instruction for switching the conditioned air blowing state in the switching mechanism unit to the control unit as necessary. A terminal, and the operation terminal includes a temperature sensor that measures the temperature in the vicinity of the operation terminal in the indoor space, and temperature information obtained by the temperature sensor is used as information for adjusting the air volume to the air volume control unit. To send.

  As described above, according to the present invention, the blowing state can be switched by the input operation to the operation terminal, and the temperature sensor is provided in the operation terminal generally placed near the user, When the temperature near the user with the operation terminal is acquired by the air volume control unit, the air volume control unit executes temperature control of the indoor space by adjusting the air volume based on this temperature, and the user's The temperature to be felt is brought close to the target temperature, and appropriate air conditioning that reliably corresponds to the user's situation can be executed.

  In addition, the air conditioning system according to the present invention switches the control unit from a state where the control unit mainly blows conditioned air mainly through the diffusion blowing unit to a state where the conditioned air is mainly blown through the local blowing unit, as necessary. After switching in step 1, the state in which the conditioned air is mainly blown out through the local blowing unit is continued for a first predetermined time, and then the switching mechanism unit is again in a state in which the conditioned air is blown out mainly through the diffusion blowing unit. The controller gradually switches over the second predetermined time, and the control unit adjusts the first predetermined time and the second predetermined time based on the temperature outside the indoor space and / or the temperature of the indoor space. It is something to control.

  As described above, according to the present invention, the time for continuing the state in which the conditioned air is mainly blown out through the local blowing unit and the state in which the conditioned air is blown out through the local blowing unit to the state in which the conditioned air is blown out through the diffusion blowing unit. The time is adjusted based on the temperature outside the indoor space and the indoor space temperature, respectively, and the time for blowing through the local blowing unit is changed according to the user's experience based on the air temperature, and the blowing is mainly performed through the local blowing unit. Slowly reduce the amount of conditioned air that is blown from the local blower from the state where the air is discharged, and then shift to the state where the air is blown from the diffuser, thereby allowing the user to get out of the local blower at an appropriate time until the user gets used to the indoor space temperature. The air can be blown out and the air conditioning for the indoor space can be performed more efficiently, and the state gradually changes from the state of blowing mainly through the local blowing part to the state of blowing through the diffusion blowing part. Without compromising the comfort of the user, not to cause discomfort to the transition to the user reasonably smoothly in the air-conditioning state using the diffusion blowout part of the indoor space.

  Further, in the air conditioning system according to the present invention, a plurality of unit areas as air conditioning objects are set in the indoor space as necessary, and one or a plurality of air outlet devices facing one unit area are provided for each unit area. And a set of one air volume adjusting unit connected to the air outlet device via a duct, respectively, one or a plurality are arranged for each unit area, and whether or not there is a person in the unit area A human sensor to detect, when the air volume control unit is input detection information of each human sensor for each unit area, and when no human presence is detected by all human sensors in a predetermined unit area, The air volume adjusting unit corresponding to the predetermined unit area executes the operation control of the air volume adjusting unit so as to reduce the air volume of the conditioned air toward the air outlet device to a preset minimum air volume.

  As described above, according to the present invention, a human sensor for detecting whether or not a person is present in the indoor space is provided, and in a situation where the user cannot be detected by the human sensor, the air volume control unit adjusts the air volume to the air volume adjusting unit. If the user is not in the indoor space, the air volume is reduced regardless of whether the conditioned air is blown out from the diffuser or local blower. Thus, useless energy consumption due to air conditioning in a space where no user exists can be suppressed, and the operating cost of the air conditioning equipment can be reduced.

  In addition, the air conditioning system according to the present invention is configured so that the unit area where a person is present is equal to or less than a predetermined ratio with respect to all the unit areas in the indoor space, based on the detection results of all the human sensors in the indoor space as necessary. When it becomes, the control part in the blower outlet apparatus of the unit area | region where a person exists makes the blowing state of a blower outlet apparatus the state which blows off conditioned air mainly through a local blower part.

  As described above, according to the present invention, the number of unit areas in which human presence can be detected by the human sensor in the indoor space is equal to or less than a predetermined ratio with respect to all unit areas, and the air volume of the unit area in which human presence cannot be detected. The amount of conditioned air supplied to the entire indoor space is significantly reduced due to the suppression of air conditioning, and other unit areas in the indoor space may affect the air conditioning to the unit area where people are present. However, the control unit of the air outlet device in the unit area where the person exists makes the air outlet state of the air outlet device a state in which conditioned air is mainly blown out through the local air outlet, and only a limited area around the person is localized. By ensuring that air conditioning is performed at the same time, it is possible to perform air conditioning that ensures human comfort efficiently with the minimum necessary amount of conditioned air supply, and the air conditioning is inefficient due to the air conditioning of the entire space. End up The can be avoided, suppressing the cost of the air conditioner.

  Moreover, the air conditioning system according to the present invention is formed as a substantially box-like body surrounding the opening having a predetermined opening cross-sectional shape through which the conditioned air passes, and the predetermined position on the ceiling, if necessary. The local blowout part is arranged at a site near the air conditioning target space in the central part of the opening, and the diffusion blowout part is arranged on the side of the local blowout part in the opening. A blower outlet body that is connected to a duct and introduces conditioned air into the opening, and is disposed at a predetermined position closer to the duct than a local blowout part inside the blower outlet body, and operates based on control of the control unit, A blower fan that feeds the delivery air into only the air passage of the local blowout portion, and at least a portion of the blowout outlet body that is disposed between the connection portion with the duct and the conditioned air inflow portion of the blower fan. And a shielding part that partitions the opening of the outlet body and divides the conditioned air into a part that goes to the local outlet and a part that goes to the diffusion outlet, and the fan for blowing is at least part of the switching mechanism part As described above, the control unit is operated in a state in which conditioned air is mainly blown out from the local blowing unit, and is inactivated in a state in which conditioned air is mainly blown out from the diffusion blowing unit.

  As described above, according to the present invention, the blower fan that sends conditioned air to the local blower part is disposed in the blower outlet body opening of the blower outlet device, and the operation of the blower fan causes the desired position from the local blower part. A state in which the conditioned air can be locally blown out, and the conditioned air is mainly guided by the diffusion blow-out section in accordance with the non-operation of the blower fan, and the air flow of the conditioned air is widely diffused from the outlet position to the air-conditioning target space. In addition to being able to conditioned air by reliably diffusing the conditioned air over a wide area of the air-conditioning target space by blowing the conditioned air flow from the diffusion blowing part of the opening to a wide range. If necessary, the blower fan is actuated so that it can be blown locally from the local blower part toward a specific narrow area where the user exists, and the air volume adjustment part supplies conditioned air to the blower outlet device. Reduced air volume Even if, by feeding reliably conditioned air to the position of the user of the residential area, it can be made the sensible temperature of the user better.

Multiple settings are made to enter. For each unit region 71, a set of a plurality of air outlet devices 10 facing one unit region and one air volume adjusting unit 20 connected to the air outlet device 10 via a duct 81 is set. (See FIG. 3).

A plurality of the outlet devices 10 are provided for each unit region 71, and all the locations in one unit region are positioned in the outlet range of any one of the outlet devices 10.
Specifically, the air outlet device 10 is formed as a substantially box-like body surrounding the opening 17 having a rectangular opening cross section, and is disposed on the ceiling 80 facing the indoor space subject to air conditioning. A blower outlet body 11 connected to the duct 81 and supplied with conditioned air, and a substantially cylindrical portion having an air passage on the inner side, is supported at a portion near the indoor space in the central portion of the opening 17 of the blower outlet body 11. Two local outlets 12 and a diffusion outlet 13 that is arranged on the side of the local outlet 12 in the opening 17 of the outlet main body 11 and blows conditioned air in a diffused state into the indoor space, A connecting portion between the blower fan 14 which is disposed at a predetermined position closer to the duct 81 than the local outlet 12 inside the outlet body 11 and operates based on control from the outside, and the duct 81 inside the outlet body 11. And blower fan A substantially box-shaped shielding portion 16 disposed around the local blowout portion 12 and the blower fan 14 inside the blowout outlet body 11 while being positioned at least between the conditioned air inflow portion 4 and the blower fan 14. It is the structure provided with the control part 18 which controls operation | movement of these.

  The said blower outlet main body 11 is the structure formed as a substantially box-shaped body made from a high-strength material such as metal that surrounds the opening 17 having a rectangular opening cross section through which conditioned air passes. In addition, an outer cone portion 11b that is expanded toward the indoor space side while maintaining a rectangular opening cross-sectional shape is formed at the end portion on the indoor space side of the outlet body 11, and the outer cone portion 11b The frame portion 11c is formed so as to protrude from the lower end portion toward the outer side with respect to the opening portion 17.

It is the structure made into the state made into the standing state. The frame portion 11c is attached to a well-known support frame 82 of a system ceiling (grid ceiling) assembled and arranged on the ceiling 80 through a well-known attachment plate 83 or the like, or directly. The main body 11 is configured to be fixed at a predetermined position on the ceiling 80 together with other ceiling-arranged devices such as the lighting fixture 84 (see FIG. 4).

  The blower outlet body 11 is connected to the duct 81 by a cylindrical neck portion 11a integrally connected to the upper side surface, supplied with conditioned air from the duct 81 through the neck portion 11a, and introduced into the opening portion 17. This is a mechanism for blowing out air from the lower part facing the indoor space to the indoor space through guidance by the local blowing unit 12 and the diffusion blowing unit 13.

  A decorative plate 19 having an opening hole that exposes the local blowing portion 12 to the indoor space is disposed in an intermediate portion sandwiched between the diffusion blowing portions 13 on the indoor space side of the opening portion 17 of the blower outlet body 11. It prevents leakage of conditioned air from other than the local blowout part.

  The neck portion 11a on the upper surface of the outlet body 11 has a substantially elliptical shape, more precisely, an elliptical opening cross-sectional shape in which the outer edge of the intermediate portion sandwiched between the semicircular portions at the ends in the major axis direction is linear. It is a cylindrical body and is configured to be connected to a conditioned air supply duct 81 in the ceiling 80.

  The local blow-out portion 12 is formed as a substantially cylindrical body having an outer peripheral portion having a spherical shape and an inner side serving as an air passage. The conditioned air is caused to flow into the inner air passage, and the conditioned air is guided and blown out in the extending direction of each air passage. These local blowout parts 12 are supported by the blower outlet main body 11 via a substantially cylindrical guide cylinder part 15 disposed so as to surround them.

  The guide tube portion 15 is formed as a substantially cylindrical body extending a predetermined length from the periphery of the local blowout portion 12 to the conditioned air inflow side of the local blowout portion 12, that is, upward, and has a substantially spherical surface of the local blowout portion 12 on the inner peripheral side. Having a curved surface portion that is slidably in contact with the outer peripheral surface of the pipe and arranged in the air outlet body 11 side by side. Each is communicated with the passage opening.

The guide tube portion 15 is supported by the curved surface portion so that the local blowing portion 12 does not fall off and supports the spherical center of the outer peripheral spherical surface of the local blowing portion so as to be rotatable. The orientation can be adjusted.
Since the decorative plate 19 is located on the indoor space side of the guide tube portion 15, only the periphery of the air passage opening portion on the indoor space side of the local blowing portion 12 is visible from the indoor space.

  The blower fan 14 is disposed at a predetermined position closer to the duct 81 than the local blowout part 12 inside the blowout outlet body 11. Specifically, the blower fan 14 is attached to an opening part on the conditioned air inflow side in each guide cylinder part 15. It operates based on the control from the outside, and feeds air to the air passage of the local blowing part 12 through the guide cylinder part 15 only.

  The blower fan 14 is a mechanism that can be switched between an operating state and a non-operating state by the control unit 18 based on a remote operation using a user operation terminal 40. The configuration of the blower fan 14 is the same as that of a known axial fan, and detailed description thereof is omitted.

The rectifying unit 15 a is disposed across the inside of the guide tube unit 15.

  The diffusion blow-out portion 13 is a combination of a plurality of substantially plate-like guide bodies 13a arranged so as to be arranged in a conical surface shape of a truncated pyramid and arranged in a plurality of sets at predetermined intervals. . The diffusion blow-out portion 13 is arranged so that the guide body inclined surface of the outermost peripheral portion faces the inner side surface of the outer cone portion 11b of the blower outlet main body 11, and any of the guide bodies 13a expands toward the indoor space side. As a form, it is the structure respectively arrange | positioned by the indoor space position on both sides which pinches | interposes the two local blowing parts 12 of the center in the opening part 17 of the blower outlet main body 11. FIG. And in the diffusion blowing part 13, it is a mechanism which advances conditioned air along each guide body 13a, blows out conditioned air so that it may become an airflow of a horizontal direction with respect to indoor space, and diffuses widely in indoor space.

  Each guide body 13a in the diffusion blow-out portion 13 is an elongated rectangular thin plate formed such that a cross-sectional shape orthogonal to the longitudinal direction is a shape having a small air resistance, and the guide bodies 13a are parallel to each other. The direction in which a plurality of lines are arranged is defined as an airflow guide direction. The structure of each diffusion blowing part 13 combined with such a guide body 13a corresponds to a structure obtained by cutting and dividing a known middle cone part used for a conventional multi-layer cone type blower outlet, and will not be described in detail.

  In addition, although it is set as the structure which uses two sets of large and small what combined the guide body 13a in the expansion shape in the diffusion blowing part 13, it does not restrict to this but provides only one set of guide bodies, or provides three or more sets. It can also be done.

  Moreover, although the two diffusion blowing parts 13 are each set as the same magnitude | size on both sides of the decorative board 19 part with the local blowing part 12, the setting of a magnitude | size is not restricted to this, A diffusion blowing part The size can be different for each.

  The shielding portion 16 is disposed at least between the connection portion with the duct and the conditioned air inflow portion of the blower fan in the outlet body 11, and partitions the opening of the outlet body 11 to conditioned air. Is divided into a part toward the blower fan 14 and another part toward the diffusion blowing part 13.

  Specifically, the shielding portion 16 is formed in a substantially box shape, and is disposed so as to surround the two guide cylinder portions 15 to which the local blowout portion 12 and the blower fan 14 are attached inside the blowout outlet body 11. It is a configuration.

  The shielding portion 16 is formed of a substantially rectangular box-shaped body made of a thin plate, and a plurality of rectangular holes 16a are arranged in a row in the long side direction of the upper surface at a predetermined pitch on the planar upper surface portion. The lower side is in an open state, and the upper surface side is positioned in the vicinity of the neck portion 11a so as to be disposed inside the outlet body 11.

  The shielding portion 16 is a plate-like body in which a plurality of holes are formed in an upper portion located between the connection portion of the air outlet body 11 with the duct 81 and the conditioned air inflow portion of the blower fan 14. An opening and closing structure is provided in which two sheets are overlapped and arranged to be slidable with each other. Specifically, two sets of substantially plate-like slide plates 16b that are slidable along the upper surface portion are arranged on the upper side of the plate-like upper surface portion of the shielding portion 16 so as to correspond to the respective blower fans 14. This is a configuration. The actuators 16 f that move and move the slide plates 16 b with respect to the upper surface of the shielding portion are arranged beside the shielding portion 16.

  The slide plate 16b is formed as a substantially rectangular thin plate having a size slightly smaller than half of the upper surface portion of the shielding portion 16, and has a plurality of holes 16c having substantially the same shape and arrangement as the holes 16a on the upper surface portion of the shielding portion 16. It is configured to be slidable in the direction in which the holes 16 c are arranged along the upper surface portion of the shielding portion 16.

  The actuator 16f is disposed beside the shielding part 16, and has a structure in which a movable part is connected to an end part on the slide plate 16b side. The fully open state in which the slide plate 16b overlaps the hole 16a on the shielding part 16 side. This is a mechanism for changing the position from the position to the position where each hole 16c is displaced in the plurality of arrangement directions of the holes 16c so as not to overlap the holes 16a.

  By adjusting the position of the slide plate 16b by the actuator 16f, the fully closed state in which the holes 16a and 16c do not overlap at all (see FIGS. 5A and 8A) and the fully opened state in which the holes 16a and 16c overlap each other. The state (see FIGS. 6B and 8B) can be switched. The actuator 16f is controlled to operate in response to switching between the operating state and the non-operating state of the blower fan 14, and when the blower fan 14 enters the operational state, the actuator 16f moves the slide plate 16b. , The holes 16a and 16c are all fully overlapped, and conversely, when the blower fan 14 is in an inoperative state, the actuator 16f moves the slide plate 16b so that the holes 16a and 16c do not overlap at all. It is a mechanism. Note that the movable mechanism itself of the actuator 16f is a known mechanism, and detailed description thereof is omitted.

  In this way, on the upper surface portion of the shielding portion 16, the slide plate 16 b is moved relative to the upper surface portion by driving by the actuator 16 f so that the holes overlap each other and the conditioned air can pass through the holes. The closed state in which the conditioned air cannot pass through the hole is switched without overlapping.

  Thereby, in the open state of the shielding part 16 upper surface part, the conditioned air passes through the hole, and flows into the inflow side opening of the local blowing part 12 via the blowing fan 14 that operates simultaneously, and blows out from the local blowing part 12. Is done. In the closed state of the upper surface portion of the shielding portion 16, the conditioned air that has reached the upper surface portion does not pass through the closed hole and moves sideways along the upper surface portion to reach the diffusion blowout portion 13, and diffuses. It blows out from the blowing part 13. In the closed state of the upper surface portion of the shielding portion 16, the blower fan 14 is also inactive, and most of the conditioned air flowing into the opening portion 17 of the outlet body from the duct side is diffused by the shielding portion 16 side. It is a mechanism that is guided to.

  Thus, the blower fan 14 and the shielding unit 16 harmonize the conditioned air toward the local blowing unit 12 and the conditioned air mainly blown through the local blowing unit 12 and the conditioned air toward the diffusion blowing unit 13. It will serve as a switching mechanism that switches between a state in which air is mainly blown out through the diffusion blower 13. Then, by controlling the blower fan 14 and the shielding unit 16 constituting the switching mechanism unit by the control unit 18, switching of the state in which the conditioned air is blown out is based on the operation of the user or set in advance. It is a mechanism that can be executed at a predetermined timing.

  The control unit 18 is provided for each air outlet device 10 and is electrically connected to the blower fan 14 in the air outlet main body 11 and the actuator 16f of the shielding part 16 so as to be in a room. The operation information signal is received from the operation terminal 40 such as a remote controller corresponding to each of the air outlet devices, and the operation of the blower fan 14 and the actuator 16f is controlled based on the signal to thereby blow the conditioned air. The state to be output is switched.

  When the control unit 18 controls the blower fan 14 or the shielding unit 16 as the switching mechanism unit to switch the blowing state of the conditioned air, the control unit 18 transmits a predetermined signal related to the blowing state switching to the air volume control unit 30. The air volume control unit 30 receives the signal from the control unit 18, and the air volume adjusting unit 20 adjusts the air volume of the conditioned air toward the outlet device 10 to an air volume corresponding to each blowing state.

  The control unit 18 receives a signal transmitted from the operation terminal 40 when the user performs a local blowing instruction operation on the operation terminal 40 while the blower fan 14 is inactive. The operating fan 14 is actuated to send conditioned air to the local blowing part 12 side, and the actuator 16f of the shielding part 16 is actuated to slide the slide plate 16b so that the upper surface part of the shielding part 16 is opened. Thereby, the conditioned air from the duct 81 is directed to the blower fan 14 side through the shortest path, and a state in which the conditioned air is mainly blown out through the local blowing unit 12 in the blowout device 10 is obtained. In this state, the conditioned air is smoothly blown out from the local blowing unit 12, and the air flow of the conditioned air can locally reach a desired area of the living area.

  And the control part 18 blows out the state which mainly blows out this conditioned air mainly through the local blowing part 12, based on the temperature outside indoor space, and the temperature of indoor space, and specifically, the temperature outside the indoor space (outside temperature) This is a mechanism that continues for a first predetermined time that is appropriately set according to the difference between the temperature of the indoor space. When the temperature difference is large, the user who has selected the state in which the conditioned air is mainly blown out through the local blowing unit 12 by the operation of the operation terminal 40 enters the indoor space from the outside, for example, and the air conditioning of the entire indoor space Considering a situation where it takes time to get used to the state, the first predetermined time is set longer. On the other hand, when the temperature difference is small, the first predetermined time is set to be short as the user who has entered the indoor space from the outside easily adjusts to the air-conditioned state of the entire indoor space.

  In addition, when the first predetermined time has elapsed, the control unit 18 re-starts from a state in which conditioned air is mainly blown out through the local blowing unit 12 to the blowing fan 14 and the shielding unit 16 that form the switching mechanism unit. In this mechanism, the conditioned air is controlled to be gradually switched over a second predetermined time to a state where the conditioned air is mainly blown out through the diffusion blowing unit 13.

  The length of the second predetermined time is also appropriately set according to the difference between the temperature outside the room space (outside temperature) and the temperature of the room space. For example, when the temperature difference is large, the first predetermined time becomes longer. Therefore, a user accustomed to contact with the conditioned air blown out through the local blowing unit 12 mainly diffuses the conditioned air in a short time. The second predetermined time is set to be longer in consideration of a situation in which a sense of incongruity is easily felt when switching to the state of blowing through the unit 13. On the other hand, when the temperature difference is small, the first predetermined time is shortened, so that the second predetermined time is set to be short as it becomes difficult to feel uncomfortable when switching in a short time.

  As a specific control of the control unit 18 that gradually switches from the blowing state through the local blowing unit 12 to the blowing state through the diffusion blowing unit in the second predetermined time, the actuator 16f of the shielding unit 16 slides. By sliding the plate 16b and gradually decreasing the opening degree of the open hole in the shielding part 16, the amount of air blown through the local blowing part 12 is reduced, and the amount of air blown through the diffusion blowing part is relatively increased. Control (see FIG. 9 (A)) and the rotational speed of the blower fan 14 are gradually reduced to reduce the amount of air blown through the local blower 12 and relatively increase the amount of blown air through the diffusion blower. Control (see FIG. 9B) is executed.

  In addition, the control unit 18 also adjusts the air flow rate by controlling the rotational speed of the blower fan 14 and adjusts the opening degree by sliding the slide plate 16b even in a situation where the local air blowing unit 12 is blowing locally. Thus, it is possible to change the degree of arrival in the vicinity of the user by adjusting the air volume of the conditioned air blown out from the local blowing section 12.

  On the other hand, the control unit 18 is transmitted from the operation terminal 40 in response to a case where the user performs an instruction operation to stop the local blowing on the operation terminal 40 in a state where the blower fan 14 is operated. In response to the signal, the operation of the blower fan 14 is forcibly stopped, the actuator 16f is operated, the slide plate 16b is slid in the opposite direction, and the upper surface portion of the shielding portion 16 is closed, so that the conditioned air is It can also be made to blow mainly from the diffusion blowing part 13.

  Note that the control unit 18 is not limited to those specializing in the control of the blower fan 14 and the actuator 16f, but is a control unit such as an illumination arranged near the air outlet device 1 in the case of a grid type system ceiling, for example, use It is also possible to adopt a configuration that also serves as a control unit that turns on / off the illumination or changes the brightness according to an instruction from the person via the operation terminal.

  The air volume adjusting unit 20 is connected to a plurality of air outlet devices 10 facing one unit region via a duct 81 and a chamber 82, and is arranged corresponding to each unit region 71, and is arranged in the upstream air conditioning. It adjusts the air volume of the conditioned air supplied from the machine (not shown) and directed to the outlet device 10 through the chamber 82 and the duct 81. The air volume adjustment unit 20 is electrically connected to the air volume control unit 30, receives a control command from the air volume control unit 30, operates under the control of the air volume control unit 30, and controls the conditioned air by the air volume control unit 30. Adjust the air volume according to

  This air volume adjustment unit 20 incorporates a sensor for detecting the passing air speed and a damper for adjusting the opening degree, and maintains the air volume set based on the control even if the supply air volume of the conditioned air from the upstream side changes. This is a known variable air volume adjustment device (VAV) that performs adjustment control so that detailed description thereof is omitted. When the air volume adjustment unit 20 performs the air volume adjustment, the air volume of the conditioned air supplied from the air conditioner or the air blower located on the upstream side of the air volume adjustment unit 20 is also adjusted in conjunction with the air volume adjustment as in the past. It is a mechanism to be done. Such a method of interlocking the air volume adjustment of the upstream air conditioner or the like is also known and will not be described.

  The chamber 82 connected to the air volume adjusting unit 20 faces the indoor space as a substantially box-like body to which the plurality of ducts 81 respectively connected to the plurality of air outlet devices 10 facing one unit region 71 are connected. A plurality of conditioned air that is disposed in the ceiling and passes through the air volume adjusting unit 20 is distributed to each outlet device 10. This chamber 82 is also a known device that distributes the supplied conditioned air to each of the air outlet devices 10 via the connected duct 81, and detailed description thereof is omitted. Further, the duct 81 is also a well-known pipe line disposed on the ceiling 80 with one end connected to the chamber 82 and the other end connected to the air outlet device 10, and detailed description thereof is omitted.

  In response to the control command from the air volume control unit 30, the air volume adjusting unit 20 performs an operation of adjusting the air volume of the conditioned air toward the air outlet device 10 so as to become the set target air volume. The air volume adjusting unit 20 sets the conditioned air to a predetermined minimum air volume by the control of the air volume control unit 30 when the presence of a person cannot be detected by the human sensor 50 provided separately. The minimum air volume is set in advance as a minimum air volume that can be ventilated with conditioned air blown out from each air outlet device 10 by allowing a part of the air in the indoor space to flow outside.

  The air volume control unit 30 is provided as a pair with each air volume adjusting unit 20, receives the temperature information of the indoor space, and the air volume adjusting unit 20 connected to the air outlet device 10 goes to the air outlet device 10. The air volume adjustment unit 20 is controlled to adjust the air volume to an appropriate amount that matches the obtained temperature with the target temperature for air conditioning. As the temperature information of the indoor space received by the air volume control unit, information on the temperature detected by the temperature sensor 41 built in the operation terminal 40 corresponding to each air outlet device 10 is used.

  Regarding the control related to the air volume adjustment of the air volume control unit 30, specifically, when the difference between the temperature obtained from the temperature sensor 41 and the target temperature for air conditioning is large, the air volume control unit 30 includes the air volume adjustment unit 20. Is controlled so as to increase the air volume of the conditioned air toward the air outlet device 10. When the temperature obtained from the temperature sensor 41 is close to or coincides with the target temperature for air conditioning, the air volume control unit 30 determines the air volume of the conditioned air that the air volume adjustment unit 20 heads toward the outlet device 10 in the indoor space. The air volume adjusting unit 20 is controlled so as to maintain the temperature at a predetermined amount that can be maintained at the target temperature.

  In addition to the air volume adjustment control based on such temperature information, the air volume control unit 30 is controlled when the control unit 18 controls the blower fan 14 and the shielding unit 16 to switch the blowing state of the conditioned air in the air outlet device 10. It is a mechanism that receives information related to the blowing state switching transmitted from the unit 18 and also controls the air volume adjusting unit 20 to adjust the air volume of the conditioned air toward the outlet device 10 to the air volume corresponding to each blowing state.

  Specifically, when the air volume control unit 30 receives information from the control unit 18 indicating that switching to a state in which conditioned air is newly blown mainly through the local blowing unit 12 has been performed, the air volume control unit 20 The air volume adjustment to reduce the air volume of the conditioned air toward the air outlet device 10 to a predetermined air volume set in advance is performed. On the other hand, when the air volume control unit 30 receives information from the control unit 18 indicating that switching to a state where the conditioned air is newly blown mainly through the diffusion blowing unit 13 has been performed, the air volume adjusting unit 20 sends the conditioned air to the conditioned air. The air volume adjustment is canceled so as to cancel the state in which the air volume is reduced.

  Thus, in addition to the normal adjustment which adjusts the air volume of the conditioned air blown out from the blower outlet device 10 to the detected temperature, it is adjusted according to each blown state, and thus varies depending on each blown state. The conditioned air can be blown out by adjusting the air volume appropriately for the person's feeling of air conditioning. In particular, in a local blowout state where the user can easily experience the airflow of conditioned air and the air conditioning effect is more prominently provided, the air volume is reduced within the range in which the user can obtain a comfortable feeling due to air conditioning. By suppressing the supply amount, energy consumption related to conditioned air supply can be suppressed while ensuring a user's comfort.

  In addition, the air volume control unit 30 receives detection information of a plurality of human sensors 50 provided for each unit area 71, and when the presence of a person is detected by any human sensor in the unit area, the air volume It is set as the state which adjusts the air volume of the conditioned air which the adjustment part 20 heads to the blower outlet apparatus 10 according to the detection temperature of a temperature sensor. On the other hand, if any human sensor in the unit area 71 cannot detect the presence of a person, the air volume adjustment unit 20 for each unit area 71 sets a predetermined minimum air volume that is set in advance as the air volume of the conditioned air that is directed to the air outlet device 10. As described above, each air volume adjustment unit 20 is controlled.

  The air volume control unit 30 receives the detection information of the human sensor 50, and performs control related to the conditioned air volume adjustment of the air volume adjustment unit 20 based on the presence / absence of human presence at a predetermined time interval (for example, several minutes). To run once). That is, the air conditioning state based on the presence of a person in each unit area 71 is updated by the air volume control unit 30 at this control interval.

  In addition, in accordance with the transition from a situation in which a person can move, such as other than working hours, which is known based on the usage pattern of the indoor space, for example, as an office, to a situation in which there is no person and no movement. Thus, the frequency of control execution of the air volume adjusting unit 20 in the air volume control unit 30 based on the signal transmission from the human sensor 50 side is reduced, that is, the control execution time interval is longer (for example, more than 10 It can also be changed once a minute).

  The operation terminal 40 is provided corresponding to each air outlet device 10 and receives the user's input operation, and switches the conditioned air blowing state in the switching mechanism to the control unit 18 of each air outlet device 10. To send instructions. Specifically, the start of a state in which conditioned air is mainly blown out through the local blowing unit 12 is instructed to be transmitted based on the operation of a switch or the like by the user. Further, the operation terminal 40 has a switch or the like that stops the state in which the conditioned air is mainly blown out through the local blowing unit 12 and forcibly switches the conditioned air to the state in which the conditioned air is blown out mainly through the diffusion blowing unit 13. Also good.

  The operation terminal 40 includes a temperature sensor 41 that measures the temperature in the vicinity of the operation terminal 40 in the indoor space, and the temperature information obtained by the temperature sensor 41 is used for air volume adjustment to the air volume control unit 30. Send as information. The operation terminal 40 is used to prevent erroneous detection of temperature in a situation where the operation terminal is not in the vicinity of the user or in a situation where the temperature sensor portion is not in direct contact with the air in the indoor space. The temperature information may be transmitted to the air volume control unit 30 only when the person carries the operation with the operation terminal 40.

Further, the operation terminal 40 is not limited to a remote control assigned to each outlet device 10, and may be a general-purpose portable communication terminal or a personal computer.
The communication between the operation terminal 40 and the control unit 18 may use wireless communication represented by standard systems such as IEEE 802.11 series and IEEE 802.15 series, in addition to a general infrared type and radio wave type using a remote controller or the like. it can.

  A plurality of the human sensors 50 are provided for each unit region 71 and detect the presence or absence of a person in each unit region 71. Specifically, the human sensor 50 is attached to a predetermined portion facing the indoor space of each outlet device 10 in each unit region 71 with the detection portion facing downward, and the sensor detection ranges in the unit region 71 are mutually connected. The arrangement is such that all the parts in one unit region are included in one of the detection ranges of the plurality of sensors so as not to overlap with each other.

  The human sensor 50 is electrically connected to the air volume control unit 30 provided for each unit region 71, transmits a detection information signal to the air volume control unit 30, and the detection information signal is input to the air volume control unit 30. As a result, the air volume control unit 30 can control the air volume of the conditioned air according to the presence or absence of a person present in the unit area. The human sensor 50 is a known pyroelectric human body detection sensor that detects a change in incident infrared rays caused by the movement of a person and outputs an electrical signal, and a detailed description thereof is omitted.

  Next, the air conditioning state to the indoor space by the air conditioning system based on the said structure is demonstrated. As a premise, as the blowout state of the outlet device 10, mainly the diffusion is performed with the blowing fan 14 in the activated state and mainly blowing the conditioned air locally through the local blowing unit 12, and the blowing fan in the non-activated state. Either of the states in which the conditioned air is diffused and blown out through the blowing unit 13 can be selected. In a normal situation, the conditioned air is blown out mainly through the diffusion blowing unit 13 and is remotely controlled by the user's operation terminal 40. It is assumed that a state in which conditioned air is locally blown out mainly through the local blowing unit 12 is selected by the operation.

  When the user does not perform any particular operation, the blowing is performed mainly in a state where the conditioned air is diffused and blown out through the diffusion blowing unit 13. In this case, the slide plate 16b is in a position where the hole is closed, and the blower fan 14 is in an inoperative state.

  The conditioned air supplied from the duct 81 smoothly proceeds to the opening 17 of the outlet body 11 through the neck portion 11 a of the outlet device 10, and travels to each position of the opening 17 including the shielding portion 16. In this state, since the hole of the shielding part 16 is closed, the conditioned air that has advanced from the duct 81 to the opening 17 of the outlet main body 11 is more likely to travel to the diffusion blowing part side than to the blowing fan side. Yes. In particular, the conditioned air that has reached the upper surface of the shielding part travels laterally on the upper surface of the shielding part and reaches the diffusion outlet 13 near the indoor space. In this way, most of the conditioned air can be surely directed to the diffusion outlet 13.

  In this case, the air flow of conditioned air is mainly blown horizontally from the diffusion blowing unit 13 into the indoor space (see FIG. 8A), and the conditioned air is reliably diffused in a wide area of the indoor space. Harmony is achieved, and the temperature of the indoor space can be adjusted uniformly.

  On the other hand, when the user mainly selects a state of locally blowing from the local blowing unit by operating the operation terminal 40, based on this, the control unit 18 activates the actuator 16f and slides by the actuator 16f. The plate 16b is moved so that the hole 16a on the upper surface of the shielding portion is changed from the closed state to the opened state. At the same time, the control unit 18 changes the blowing fan 14 from the non-operating state to the operating state. Further, at this time, the control unit 18 transmits information indicating that switching to a state in which conditioned air is mainly blown out through the local blowing unit 12 is performed to the air volume control unit 30.

The conditioned air supplied from the duct 81 smoothly proceeds to the opening 17 through the neck portion 11a of the outlet body 11 and travels to each position of the opening 17 including the shielding portion 16.
In this state, the conditioned air that has advanced from the duct 81 into the outlet body is caused to flow into the blower fan through the hole 16a of the shielding portion 16 while maintaining the delivery speed from the duct 81 as much as possible. Can be operated to add blast pressure to the conditioned air, and the conditioned air can be sent to the local blower 12 closer to the indoor space through the guide tube 15.

  Accordingly, conditioned air is locally blown out mainly from the local blowing unit 12 toward a specific narrow area of the indoor space where the user exists. Then, the conditioned air is intensively blown from the local blowing unit 12 to a narrow range of the indoor space, so that the conditioned air can reach the position of the user in the living area, and the cool air from the airflow hitting the user's body or An excellent sensation temperature adjustment state that allows the user to quickly experience a warm state, such as allowing the user to experience the warmth directly, can be obtained.

  In this state, the air volume control unit 30 receives the information related to the switching of the blowing state from the control unit 18, and the air volume adjusting unit 20 blows the air volume of the conditioned air toward the outlet device 10 through the diffusion blowing unit 13. The air volume is adjusted to a predetermined air volume that is set in advance by reducing the air volume. For this reason, while the user can be in contact with the locally blown airflow of the conditioned air and obtain a state of comfort based on the air conditioning, the air volume can be moderately suppressed. It is possible to reduce the air conditioning cost by suppressing the energy related to the feeding.

  In addition, by arrange | positioning the local blowing part 12 with respect to the blower outlet main body 11 so that rotation is possible, rotation direction of the local blower part 12 is adjusted with respect to the blower outlet main body 11, and the direction of the opening which faces indoor space is adjusted. It is possible to change and to change the blowing direction of the conditioned air. The user can arbitrarily adjust the direction in which the conditioned air is blown within a range in which the opening portion on the indoor space side of the local blowing portion can be exposed from the opening hole portion of the decorative plate 19 (see FIG. 6B). The blowing direction can be appropriately set according to the situation of the user in the living area, and air conditioning can be performed efficiently.

  Based on the operation of the user, after the conditioned air is mainly blown out through the local blowing unit 12, the control unit 18 changes the state of blowing out the conditioned air mainly through the local blowing unit 12, such as the outside air temperature. For a first predetermined time set based on.

  The first predetermined time during which the state in which the conditioned air is mainly blown out through the local blowing unit 12 is continued in the control unit 18 according to, for example, the difference between the temperature outside the indoor space (outside temperature) and the temperature in the indoor space. Is set. If the temperature difference is large, the first predetermined time is set to be long so that the user who has entered the indoor space from the outside feels comfortable in contact with the local airflow, and the air in the indoor space Can provide enough time to get used to the harmonious state. Conversely, when the temperature difference is small, even if the first predetermined time is set short, the user who has entered the indoor space from the outside can be easily adapted to the air-conditioned state of the indoor space. In any case, by utilizing the local airflow of conditioned air, it is possible to efficiently obtain a comfortable state for the user as compared to a state in which conditioned air is mainly blown out through the diffusion blowing unit 13.

  Then, when the first predetermined time has elapsed, the process of returning from the state in which the conditioned air is mainly blown out through the local blowing unit 12 to the state in which the conditioned air is blown out through the normal diffusion blowing unit 13 starts. The control unit 18 gradually switches to a state in which conditioned air is mainly blown out through the diffusion blowing unit 13 over a second predetermined time. Specifically, the control unit 18 moves the slide plate 16b by the actuator 16f of the shielding unit 16 to change the hole of the shielding unit 16 from the open state to the closed state and / or removes the blower fan 14 from the operating state. The process of lowering the rotational speed and making it inoperative is gradually executed in a second predetermined time (see FIG. 9).

  The control unit 18 gradually switches the conditioned air to a state in which the conditioned air is mainly blown out through the diffusion blowing unit 13 after the first predetermined time, so that the local conditioned air flow is The user who gets used to contact with the local conditioned air flow blown out through the local blow-out unit 12 does not feel a sense of incongruity as if the local air flow attenuates rapidly. Easy to maintain comfort through air conditioning.

  In the state where the conditioned air is mainly blown out through the diffusion blowing portion 13 after the switching, the conditioned air which has advanced from the duct 81 to the opening portion 17 of the outlet main body 11 by closing the hole of the shielding portion 16 as described above. Becomes easier to travel from the blower fan side to the diffusion blowing unit 13 side, and the air flow of the conditioned air is blown from the diffusion blowing unit 13 to a wide range, and the conditioned air is reliably diffused in a wide area of the indoor space. Harmony can be done.

  Further, at the time of switching the blowing state, the control unit 18 transmits information indicating that switching to a state in which conditioned air is mainly blown out through the diffusion blowing unit 13 has been performed to the air volume control unit 30. And the air volume control part 30 will cancel | release the state which reduced the air volume of the conditioned air according to previous switching to the air volume adjustment part 20, if the information from the control part 18 is received (an air volume is returned to the original). Adjust the air volume. For this reason, after switching to a state in which conditioned air is mainly blown from the diffusion blowing unit 13, a conditioned air having a sufficient air volume is diffused and blown from the diffusion blowing unit 13, and a unit region corresponding to the blowout device 10. The conditioned air can surely reach each part of the above.

  In addition, during the execution of such air conditioning, the air volume control unit 30 receives the temperature information of the indoor space detected by the temperature sensor 41 built in the operation terminal 40, and calculates the air volume of the conditioned air toward the outlet device 10. The air volume adjustment unit 20 adjusts the air volume so that the measured temperature of the obtained indoor space and the target temperature for air conditioning can be matched to each other. When the difference between the temperature obtained from the temperature sensor 41 and the target temperature for air conditioning is large, the air volume control unit 30 causes the air volume adjusting unit 20 to increase the air volume of the conditioned air so that the conditioned air is discharged into the indoor space. The influence of temperature is strongly applied, and the temperature of the indoor space is quickly brought close to the target temperature.

  In addition, when the temperature obtained from the temperature sensor 41 is close to or coincides with the target temperature for air conditioning, the air volume control unit 30 extremely reduces the air volume of the conditioned air that the air volume adjustment unit 20 heads toward the outlet device 10. Control is performed so that the temperature of the indoor space is maintained at the target temperature while maintaining an appropriate amount without changing.

  The temperature of the position where the user in the living area is active is measured by the temperature sensor 41 of the operation terminal 40, and the obtained temperature information is transmitted to the air volume control unit 30, and based on this temperature information, the air volume adjusting unit 20 Since the air volume control is executed, the temperature adjustment suitable for the user's feeling can be performed by the control based on the temperature near the user, and the comfort of the indoor space can be improved.

  Further, the air volume control unit 30 receives the detection information of the human sensor 50 and executes control related to the air volume adjustment, and any one of the human sensors 50 in the unit area 71 of each corresponding outlet device. When the presence of a person is detected, the air volume adjustment by the air volume adjusting unit 20 corresponding to the temperature detected by the temperature sensor 41 is executed as usual. However, when the presence of a person can no longer be detected by all the human sensors 50 in the unit region 71, the air volume control unit 30 that has received the information is conditioned air from which the air volume adjusting unit 20 is directed toward the air outlet device 10. Control is performed so that the air volume is set to a preset minimum air volume, and the necessary minimum ventilation state in the unit area of the indoor space is ensured, while unnecessary supply of conditioned air is prevented and wasteful energy consumption is suppressed. Thereby, air conditioning can be advanced more efficiently.

  Thus, in the air conditioning system which concerns on this embodiment, it has the local blowing part 12 and the diffusion blowing part 13 as the blower outlet apparatus 10, and is mainly conditioned air to the desired position of indoor space through the local blowing part 12. Can be selected between a state in which the air is blown locally and a state in which the air flow of the conditioned air is diffused widely into the indoor space mainly through the diffusion blowing unit 13 and the amount of the conditioned air to be blown out is In addition to the normal adjustment to match the temperature, it is also adjusted to correspond to each blowing state, so that conditioned air is blown from the diffusion blowing portion 13 of the blowout device 10 to a wide range, and in a wide area of the indoor space, By appropriately switching between a state in which conditioned air can be reliably diffused and air conditioning can be performed, and a state in which local air is blown out locally from the local blowing unit 12 toward a specific narrow region, It is possible to blow out conditioned air by adjusting to an appropriate air volume suitable for the user's ease of experiencing the air-conditioning effect, while ensuring a comfortable feeling based on air-conditioning for the user of the indoor space, Air conditioning can be performed efficiently by reducing the chances of conditioned air supply with a large air volume that changes the whole uniformly, and the cost of air conditioning can be reduced.

  In addition, in the air conditioning system which concerns on the said embodiment, although it is set as the structure which arrange | positions the two local blowing parts 12 and the two sets of diffusion blowing parts 13 which pinch | interpose these as a conditioned air blowing part of the blower outlet apparatus 10, it is local. The number and arrangement of the blowout portions and the diffusion blowout portions are not limited to this. For example, as shown in FIG. 10, four local blowout portions 12 are provided, and four sets are provided in a peripheral portion surrounding these local blowout portions 12. It can also be set as the structure which arrange | positions the diffusion blowing part 13 of this.

  In this case, the air outlet body 11 of the air outlet device 10 is a substantially box-like body surrounding the opening of the square opening cross section, and is attached to the grid system ceiling support frame 82 in the ceiling 80 via the mounting plate 83. In the state that it can be fixed to the ceiling 80 and thus arranged on the ceiling 80, as in the above-described embodiment, the conditioned air is blown horizontally from each diffusion blowing portion 13 on the outer peripheral portion to be widely diffused in the indoor space. Accordingly, the air flow of the conditioned air can reach the arbitrary position in the living area from the local blowing portion 12 capable of adjusting the blowing direction, so that the air conditioning can be performed locally.

  Moreover, in the air conditioning system which concerns on the said embodiment, the control part 18 corresponding to the blower outlet apparatus 10 one-to-one is received, this control part 18 receives the signal from the terminal 40 for operation on the user side, and a switching mechanism It is configured to control the operation of the blower fan 14 as a part and the actuator 16f of the shielding part 16, but in addition to this, a communication terminal such as a mobile phone or a smartphone of a user who is resident in the room, a computer, etc. A communication control unit that receives operation information signals on behalf of a telephone line network and a network, and an operation control unit that performs operation control corresponding to each of a plurality of indoor outlet devices. However, among the operation control units, an operation command signal may be sent to the operation control unit of the outlet device corresponding to the position of the user operated from the communication terminal. Other than apparatus dedicated remote control, even from a general mobile communication terminal or the like, the user becomes possible instruction operation for execution of local blowing in the air outlet is caused to further improve convenience.

  In this case, first, the communication control unit receives a signal of operation information transmitted from a communication terminal such as a mobile phone of a predetermined user in the living area of the indoor space, and the communication control unit transmits the signal of the operation information. By recognizing the original communication terminal and the user, the position of the outlet device to be operated is determined at a predetermined indoor location associated with the user in advance. And a communication control part sends an operation command signal to the operation control part corresponding to the blower outlet device in this operation object position, and the operation control part which received this performs operation control of a fan for blowers, or a shielding part It becomes.

  Further, in the air conditioning system according to the embodiment, the blower fan 14 controlled by the control unit 18 of the air outlet device 10 and the actuator 16f of the shielding unit 16 are used as a switching mechanism unit, and the control unit 18 is used for blowing air. The operation and non-operation of the fan 14 are switched, and the slide plate 16b is slid by the actuator 16f to switch the open / close state of the upper surface of the shield 16 so that the conditioned air is opened and the fan 14 blows air. However, not only this but the state which blows out through the local blowing part 12 and the state which blows out mainly through the diffusion blowing part 13 by the guidance of the shielding part 16 in which the conditioned air is closed can be switched. As a mechanism, a mechanism other than the blower fan and the shielding unit, for example, in the air outlet device, directly switches the passage of conditioned air flowing from the duct, and the station Mechanism for selecting whether to direct the spread blowout unit or to direct the outlet unit, and the like can also be configured to use.

  Moreover, in the air conditioning system which concerns on the said embodiment, the control part 18 switches the blowing state of conditioned air into the state which blows out conditioned air locally mainly through the local blowing part 12 based on a user's operation. After this, when the first predetermined time has elapsed, it is configured to automatically return to the state where the air is mainly blown out through the diffusion blowing unit 13, but the present invention is not limited thereto, and the user can Regardless of the progress, when the operation terminal is operated, the control unit that has received the operation terminal can also be configured to cancel the state of blowing locally through the local blowing unit.

  In this case as well, the normal state mainly returns to the state of being diffused and blown out through the diffusion blowout part, the slide plate is moved by the actuator to change the hole from the open state to the closed state, and the blower fan is From the operating state to the non-operating state. In this state, the conditioned air that has advanced from the duct to the opening of the air outlet body is more likely to travel from the blower fan side to the diffuser air outlet side by closing the hole of the shielding part, Air can be conditioned by blowing air from a diffusion blow-out part mainly over a wide area and diffusing conditioned air reliably in a wide area of the indoor space.

  In the air conditioning system according to the embodiment, the temperature information acquired by the temperature sensor 41 of the operation terminal 40 is used for the control related to the air volume adjustment in the air volume control unit 30. The temperature information obtained by the temperature sensor 41 of the terminal 40 may be transmitted to a control unit such as a blower fan of the outlet device, and the control unit may increase the target temperature, for example, the temperature in the vicinity of the user. If this is the case, control to reduce the airflow of conditioned air that reaches the living area locally, such as by reducing the rotational speed of the blower fan or sliding the slide plate to lower the opening ratio of the upper surface of the shielding part May be executed.

  Furthermore, in the air conditioning system according to the embodiment, when the control unit 18 once switches the blower fan 14 to the operating state based on the operation of the user operation terminal 40, the first predetermined time elapses. The control unit 18 is configured to maintain the operating state of the blower fan 14, but is not limited thereto, and is provided in a part of the human sensor 50 and / or the operation terminal 40 corresponding to the air outlet device 10. When the presence sensor is identified by the presence sensor, the presence of the person in the predetermined area of the living area, which is the target of the conditioned air blowing from the local blowing unit 12, is identified by the presence sensor. Can also be configured to put the blower fan in a non-operating state. In the state where the conditioned air is mainly blown locally through the local blowing section, when there is no target user, it is not necessary to make the conditioned air flow reach the living area until the blast fan is used. Therefore, by stopping the blower fan without operating it, the energy consumption related to the operation of the blower fan can be reduced, and the air conditioning cost can be suppressed.

  In this case, in accordance with the stop of the blower fan, the sliding plate is slid to close the upper surface portion of the shielding portion, and the local blowing from the local blowing portion itself can be stopped. That is, when the user leaves the target area where the air flow of the conditioned air reaches the predetermined time or more while the blast air is in a state where the conditioned air is mainly blown locally through the local blowing section, the conditioned air is quickly diffused and blown out. By changing to a blowout state that diffuses widely in the indoor space, the conditioned air that was about to be blown locally to some areas can be effectively used for air conditioning for the entire indoor space, On the other hand, air conditioning can be performed efficiently.

  In addition to such a human sensor, a temperature sensor 41 provided in a part of the operation terminal 40 is used to control the temperature in a predetermined area of the living area, which is a target of conditioned air blowing from the local blowing unit, with the temperature sensor 41. When the measured and obtained temperature is significantly different from the target temperature in the air conditioning of the entire room, the control unit 18 may be configured to control each unit so as to stop the local blowing from the local blowing unit. In an inadequate air conditioning situation where the temperature of the indoor space is not yet uniform, such as immediately after starting the air conditioning for an indoor space that has been stopped for a while, air conditioning for the entire indoor space As a priority, it is possible to shift the indoor space to an overall comfortable temperature state in as short a time as possible.

(Second embodiment of the present invention)
In the air conditioning system according to the first embodiment, the indoor space 70 is divided into a plurality of unit areas 71, and the presence / absence of a person is detected for each unit area 71 by the human sensor 50. When there is no person, the air volume adjusting unit 20 restricts the air volume of the conditioned air toward the air outlet device 10 so that the conditioned air is blown out from the air outlet device 10 to the minimum necessary air volume state. Although the control unit 30 is configured to perform control, in addition to this, as a second embodiment, as shown in FIGS. 11 and 12, the detection information of all human sensors in the indoor space is received, and the entire indoor space is received. And a general control unit 35 that performs control based on the presence state of the person in the unit area, and based on the detection results of all the human sensors 50 in the indoor space, the unit area 71 where the person exists is included in all the indoor spaces. Unit territory When the ratio is less than or equal to a predetermined ratio, the blowout state of the blowout device 10 in the unit region 71 where a person is present is configured so that the conditioned air is blown mainly through the local blowout unit 12. You can also.

The general control unit 35 receives detection information of all the human sensors 50 in the indoor space 70 as a higher-order control part that gives a control instruction to the control unit 18 for each air outlet device 10, and the human sensor 50 receives the human information. When the unit area 71 in which the presence of the air has been detected falls below a predetermined ratio (for example, 25%) with respect to all the unit areas of the indoor space 70, the control unit 18 of the outlet device 10 in the unit area has the conditioned air A blowing state switching instruction is transmitted.
And the control part 18 in the blower outlet apparatus 10 of the unit area where a person exists performs control so that the blowing state of the blower outlet apparatus 10 will be in the state which blows off conditioned air mainly through the local blower part 12. FIG.

  As a result of detection by the human sensor 50, the number of unit areas in which the presence of the person can be detected by the human sensor 50 is equal to or less than a predetermined ratio with respect to all the unit areas in the indoor space. In the state in which most of the indoor space is occupied, as in the first embodiment, the air volume in the unit area where the presence of the person cannot be detected by the human sensor 50 is suppressed and becomes the minimum air volume, so that The supply of conditioned air is significantly reduced. In this case, the air conditioning of the entire indoor space due to the presence of other unit regions that do not supply sufficient conditioned air only by air conditioning through the normal diffusion blowing unit to the unit region 71 where a person exists. Due to the influence of the load, there is a possibility that air conditioning to a unit area where a person exists cannot be sufficiently performed.

  At this time, the control unit 18 of the outlet device 10 in the unit region 71 where a person is present is switched to a state in which conditioned air is blown out mainly through the local outlet 12 (already mainly in the local outlet). In the state where the conditioned air is blown out through the unit 12), the air conditioning targeting the entire space of the unit area mainly through the blowout through the diffusion blowing unit 13 is temporarily stopped, and the limited area around the person If air conditioning is performed only locally, air conditioning that efficiently secures human comfort can be performed with the minimum necessary conditioned air supply. Thereby, aiming at the air conditioning of the whole space to the last, the air conditioning of the unit area | region where a person does not exist is performed in order to supplement the air conditioning capability with respect to a load, and it can prevent becoming inefficient.

  In this case, in order to provide an appropriate air-conditioning effect for the user, the user is notified by a notifying means of the blowing state change to the state in which the conditioned air is blown out through the local blowing unit 12 in the blow-out device 10. If necessary, it is desirable to prompt the user to make adjustments so that the blowing direction of the local blowing unit 12 is correctly directed to the user.

  In addition, about the control part 18 of each blower outlet apparatus 10, and the air volume control part 30 including the comprehensive control part 35, what was integrated into any one of three types, or all, and was integrated as one control part. It can also be set as the structure which has a some control function. Further, the control unit 18 of each air outlet device 10 may not be individually arranged for each air outlet device, but may be collectively arranged for each of the air outlet devices.
