(1) Configuration of Air Conditioner FIG. 1 is a perspective view of a ceiling-mounted type (more specifically, a suspended ceiling type) air conditioner 1 according to an embodiment of the air conditioner of the present invention. FIG. 2 is a schematic side sectional view of the air conditioner 1.

The air conditioner 1 is an air conditioner that blows air into the room after inhaling air from the room and exchanging heat. The air conditioner 1 includes a rectangular box-shaped casing 2 installed on the ceiling U in the room. The casing 2 mainly has an inlet 21 for sucking air from the room and an outlet 22 for blowing air into the room.
The suction port 21 is a square-shaped opening disposed at the approximate center of the lower surface of the casing 2. The suction port 21 is provided with a filter 23 for removing dust and the like contained in air sucked from the room. The filter 23 is supported by a suction grill 24 mounted on the lower surface of the casing 2.

  A plurality of air outlets 22 are formed on the side surface of the casing 2 so as to surround the inlet 21. More specifically, the air outlet 22 is disposed on each of the four side surfaces of the rectangular box-shaped casing 2. And each blower outlet 22 is comprised from the 1st blower outlet 22a and the 2nd blower outlet 22b. The first air outlet 22 a is a rectangular opening arranged at the approximate center in the vertical direction of the side surface of the casing 2. And each 1st blower outlet 22a is provided with the horizontal blade | wing 25 for controlling the wind direction of the air which blows off indoors from the 1st blower outlet 22a. The 2nd blower outlet 22b is a rectangular-shaped opening arrange | positioned away from the 1st blower outlet 22a above the 1st blower outlet 22a. And each 2nd blower outlet 22b can blow off air indoors along the ceiling U. As shown in FIG. Moreover, each 1st blower outlet 22a can blow off air in the room | chamber interior from the position near the inlet 21 rather than the 2nd blower outlet 22b.

  In the casing 2, there is provided a blower fan 3 for sucking indoor air into the casing 2 from the suction port 21 and blowing it out from the blowout port 22 into the room. The blower fan 3 is a turbo fan in which a plurality of blades 33 are held between the shroud 31 and the end plate 32. The blower fan 3 is disposed in the approximate center in the casing 2. A fan motor 34 for driving the blower fan 3 is fixed by a bolt or the like substantially at the center of the top surface of the casing 2. The drive shaft of the fan motor 34 extends downward, and the end plate 32 of the blower fan 3 is pivotally supported. A bell mouth 35 is provided below the blower fan 3 to guide the air flowing into the casing 2 from the suction port 21 into the blower fan 3. The blower fan 3 can be driven to rotate by the fan motor 34, so that air can be sucked into the inside from the lower side via the bell mouth 35 and blown out to the outer peripheral side.

  A heat exchanger 4 is provided in the casing 2 for cooling and heating air sucked from the room. The heat exchanger 4 is a cross fin tube type heat exchanger composed of a large number of plate fins arranged in parallel to each other and a plurality of heat transfer tubes passing through these plate fins in the plate thickness direction. The heat exchanger 4 is disposed so as to surround the outer periphery of the blower fan 3. The heat exchanger 4 is connected to a heat source unit (not shown) via a refrigerant pipe, and functions as an evaporator for the refrigerant flowing in the heat transfer pipe when performing indoor cooling, and when performing indoor heating. By functioning as a condenser of the refrigerant flowing in the heat transfer tube, the air blown to the outer peripheral side of the blower fan 3 and passing through the heat exchanger 4 can be cooled or heated. Further, a drain pan 5 for receiving drain water generated in the heat exchanger 4 is provided below the heat exchanger 4. Further, the heat exchanger 4 is disposed between the upper end portion and the top surface of the casing 2 with a flow path 6 for allowing a part of the air blown to the outer peripheral side of the blower fan 3 to flow. . And the flow path 6 is connected to the 2nd blower outlet 22b of each blower outlet 22 by the wall part 26 which partitions off between the 1st blower outlet 22a and the 2nd blower outlet 22b in this embodiment.

  The air conditioner 1 further includes a damper 7 that can open and close the flow path 6. The damper 7 is arrange | positioned corresponding to each blower outlet 22, ie, each 2nd blower outlet 22b. In the present embodiment, the damper 7 has a plate-like member that can be rotated by a drive mechanism such as a motor (not shown), and air is circulated through the flow path 6 by being in a state indicated by a solid line in FIG. A possible state (hereinafter, referred to as an open state) is set to a state indicated by a broken line in FIG. 2 so that air does not flow through the flow path 6 (hereinafter, referred to as a closed state). The damper 7 can adjust the flow rate of the air flowing through the flow path 6 by setting the damper 7 to an intermediate state between the open state and the closed state (hereinafter referred to as a small open state). Thus, as shown in FIG. 4, the damper 7 passes the air F sucked into the casing 2 from the suction port 21 through the heat exchanger 4 and then passes through the first blower port 22 a of the blower port 22 to the room. The heat exchange passing air F1 blown to the air and the heat exchange avoidance air F2 blown into the room from the second air outlet 22b of the air outlet 22 without passing through the heat exchanger 4, and the heat exchange passing air It has a function as a flow rate adjusting mechanism that adjusts the flow rate of F1 and the flow rate of heat exchange avoidance air F2. Further, in the present embodiment, each damper 7 is configured to be individually controllable, such as individually including a drive mechanism.

(2) Operation | movement of an air conditioning apparatus Next, operation | movement of the air conditioning apparatus 1 of this embodiment is demonstrated.
Here, the single operation of the air conditioner 1, the operation when one air conditioner 1 is arranged in a single space, and the plurality of air conditioners including the air conditioner 1 are arranged in a single space. The operation of the case will be described.

<Single operation of the air conditioner 1>
First, the operation when the air conditioner 1 is operated in a closed state (that is, a state indicated by a broken line in FIG. 3) will be described with reference to FIG. 3.
When the blower fan 3 is rotationally driven by the fan motor 34, indoor air is sucked into the casing 2 through the suction port 21 and the filter 23. The air F sucked into the casing 2 is guided into the blower fan 3 by the bell mouth 35 and blown out to the outer peripheral side of the blower fan 3 by the rotating blades 33. The air blown to the outer peripheral side from the blower fan 3 is cooled during the cooling operation by passing through the heat exchanger 4 without being branched to the flow path 6 side because the damper 7 is in the closed state. Sometimes after being heated, the heat exchange passing air F1 is blown into the room from each outlet 22 (specifically, each first outlet 22a). Then, the heat exchange passing air F1 is blown obliquely downward with the air direction controlled by the horizontal blades 25 provided at each first air outlet 22a.

As described above, when the air conditioner 1 is operated with the dampers 7 in the closed state, all the air F sucked from the suction ports 21 passes through the heat exchanger 4 from the air outlets 22. It becomes excess air F1 and is blown into the room.
Next, the operation when the air conditioner 1 is operated with the damper 7 in the open state (that is, the state shown by the solid line in FIG. 4) will be described with reference to FIG.

  When the blower fan 3 is rotationally driven by the fan motor 34, indoor air is sucked into the casing 2 through the suction port 21 and the filter 23. The air F sucked into the casing 2 is guided into the blower fan 3 by the bell mouth 35 and blown out to the outer peripheral side of the blower fan 3 by the rotating blades 33. Since the air blown out from the blower fan 3 to the outer peripheral side is in the open state, the flow is branched to the heat exchanger 4 side and the flow path 6 side. The air branched to the heat exchanger 4 side passes through the heat exchanger 4, and is cooled during the cooling operation and heated during the heating operation. Are blown out into the room from each first outlet 22a). The heat exchange passing air F1 is blown out in an obliquely downward direction with the air direction being controlled by the horizontal blades 25 provided in the first air outlets 22a. On the other hand, the air branched to the flow path 6 side is blown into the room from each outlet 22 (specifically, each second outlet 22b) as heat exchange avoidance air F2 without passing through the heat exchanger 4. Is done. And the heat exchange avoidance air F2 is blown out along the ceiling U from the upper side of the heat exchange passage air F1.

  As described above, when the air conditioner 1 is operated with each damper 7 open, the air F sucked from the suction ports 21 passes through the heat exchange air that has passed through the heat exchanger 4 from each blower port 22. F1 and the heat exchange avoidance air F2 that does not pass through the heat exchanger 4 are blown out from the air outlets 22 into the room. Here, the heat exchange avoidance air F <b> 2 is blown out along the ceiling U from the second blower outlet 22 b of the blower outlet 22, and the heat exchange passing air F <b> 1 is the first of the blower outlet 22 formed at a position close to the inlet 21. Since the air is blown out from one air outlet 22a, the flow rate of the heat exchange passing air F1 blown out from the air outlet 22 in the space immediately below the air inlet 21 compared to the flow rate of the air F sucked from the air inlet 21. There is little state. Then, since the space immediately below the suction port 21 is in a slightly lower pressure than the surrounding space, the heat exchange air F1 blown into the room from the blowout port 22 is easily sucked from the suction port 21. In this state (hereinafter referred to as a weak short circuit state), the heat exchange passing air F1 is hardly diffused from the space near the air conditioner 1 (specifically, the space immediately below the suction port 21). Thereby, the state (henceforth zone air conditioning) which actively air-conditions the space near the air conditioning apparatus 1 is realizable.

<When one air conditioner 1 is arranged in a single space>
Next, the operation when one air conditioner 1 is arranged in a single space, in particular, the air conditioner 1 in the open state (that is, the state shown by the solid line in FIG. 4) with the damper 7 described above opened. A case where zone air-conditioning is performed using the operation in the case of driving will be described.
When the air conditioner 1 is operated with the damper 7 open, as shown in FIG. 5, only the space S <b> 1 near the user A that is directly below the air conditioner 1 among the spaces S in which the air conditioner 1 is disposed. On the other hand, zone air-conditioning can be performed by the heat exchange passing air F1 blown out from the air conditioner 1. At this time, since the degree of the weak short circuit state can be changed by changing the opening degree of the damper 7 and adjusting the flow rate of the heat exchange avoidance air F2, for example, the heat exchange is performed with the damper 7 in a small open state. By reducing the flow rate of the avoidance air F2 and increasing the flow rate of the heat exchange passing air F1, the degree of the weak short circuit state is relaxed and the directivity is slightly weakened, but the range of the space S1 in which the zone air conditioning is performed is expanded. be able to. Further, since the dampers 7 can be individually controlled, in FIG. 5, for example, when zone air conditioning is performed only on the right half space including the space S1 in which the user A is present in the space S, the user A in FIG. In order to air-condition the right side space, only the damper 7 provided corresponding to the air outlet 22 facing the right side space of the user A in FIG. Only the damper 7 provided corresponding to the outlet 22 can be opened (see FIG. 4).

<When a plurality of air conditioners including the air conditioner 1 are arranged in a single space>
Next, the operation when a plurality of air conditioners including the air conditioner 1 are arranged in a single space, in particular, the damper 7 described above is in an open state (that is, a state shown by a solid line in FIG. 4). A case where processing air is exchanged between the zone air-conditioning system and the air-conditioning apparatus using the operation when the air-conditioning apparatus 1 is operated will be described.

  For example, as shown in FIG. 6, when two air conditioners 1 of the present embodiment are arranged in the space S, the air conditioner 1 arranged corresponding to the space S1 (the right space in FIG. 6). It is assumed that there is a user A directly below the user A, and there are users B and C near the air conditioner 1 arranged corresponding to the space S2 (the space on the left side in FIG. 6). Here, when the user A desires air conditioning at a set temperature different from that of the other users B and C, the air conditioner 1 directly above the user A is used to perform zone air conditioning only in the space S1 where the user A is present. The dampers 7 are opened, and the heat exchange avoidance air F2 is blown out along the ceiling U, and the heat exchange passing air F1 is blown obliquely downward (see FIG. 4). Then, in the space S2 where the users B and C are present, an operation is performed in which each damper 7 is closed and only the heat exchange passing air F1 is blown obliquely downward (see FIG. 3). Then, the heat exchange avoidance air F2 blown out from the air conditioner 1 arranged corresponding to the space S2 is sent to the air conditioner 1 side arranged corresponding to the space S2. And in the air conditioning apparatus 1 arrange | positioned corresponding to space S2, the operation | movement which suck | inhales the air containing this heat exchange avoidance air F2 from the suction inlet 21, and blows it out as the heat exchange passage air F2 is performed. As described above, in the air conditioner 1 of the present embodiment, when arranged as one of a plurality of air conditioners in a single space S, the adjacent air conditioner (corresponding to the space S2 in FIG. 6). Since each damper 7 can be controlled so as to send the heat exchange avoidance air F2 toward the air conditioner 1) arranged in the same manner, the heat exchange avoidance air F2 can be sent to the adjacent air conditioner 1. . That is, the air conditioner 1 can perform not only zone air conditioning but also exchange of processing air with other air conditioners arranged in the vicinity.
