Thus, the air dehumidified by the first adsorption heat exchanger 22a is supplied into the living room as supply air (SA) from the air supply port 35a. On the other hand, room air (RA) passes through the second adsorption heat exchanger 23a. Here, when the adsorbent of the second adsorption heat exchanger 23a functioning as a condenser is heated and the moisture adsorbed on the adsorbent is desorbed, the moisture is given to the air and the second adsorption heat exchanger. The adsorbent 23a is regenerated.

Here, the moisture in the air is adsorbed by the adsorbent of the second adsorption heat exchanger 23a functioning as an evaporator. The adsorption heat generated at this time is used as the evaporation heat of the refrigerant in the second adsorption heat exchanger 23a. Thus, the air dehumidified by the second adsorption heat exchanger 23a is supplied into the living room as supply air (SA) from the air supply port 35a. On the other hand, room air (RA) passes the 1st adsorption heat exchanger 22a. Here, when the adsorbent of the first adsorption heat exchanger 22a functioning as a condenser is heated and moisture adsorbed on the adsorbent is desorbed, the moisture is added to the air and the first adsorption heat exchanger. The adsorbent 22a is regenerated. In this way, the air used for the regeneration of the adsorbent of the first adsorption heat exchanger 22a is discharged out of the room as exhaust air (EA) from the exhaust port 34a.

  Next, the first operation of the humidifying operation will be described. In the first operation of the humidifying operation, outdoor air (OA) passes through the first adsorption heat exchanger 22a by operating a switching mechanism (not shown) made of a damper or the like. Here, when the adsorbent of the first adsorption heat exchanger 22a functioning as a condenser is heated and moisture adsorbed on the adsorbent is desorbed, this moisture is imparted to the air. In this way, the air humidified by the first adsorption heat exchanger 22a is supplied to the living room as supply air (SA) from the air supply port 35a. On the other hand, room air (RA) passes through the second adsorption heat exchanger 23a. Here, the moisture in the air is adsorbed by the adsorbent of the second adsorption heat exchanger 23a functioning as an evaporator. The adsorption heat generated at this time is used as the evaporation heat of the refrigerant in the second adsorption heat exchanger 23a. Thus, the air which gave the water | moisture content to the adsorbent of the 2nd adsorption heat exchanger 23a is discharged | emitted out of the room as exhaust air (EA) from the exhaust port 34a.

  Next, the second operation during the humidifying operation will be described. In the second operation of the humidifying operation, outdoor air (OA) passes through the second adsorption heat exchanger 23a by an operation of a switching mechanism (not shown) including a damper or the like. Here, when the adsorbent of the second adsorption heat exchanger 23a functioning as a condenser is heated and moisture adsorbed on the adsorbent is desorbed, this moisture is imparted to the air. In this way, the air humidified by the second adsorption heat exchanger 23a is supplied to the living room as supply air (SA) from the air supply port 35a. On the other hand, room air (RA) passes the 1st adsorption heat exchanger 22a. Here, the moisture in the air is adsorbed by the adsorbent of the first adsorption heat exchanger 22a functioning as an evaporator. The adsorption heat generated at this time is used as the evaporation heat of the refrigerant in the first adsorption heat exchanger 22a. Thus, the air which gave the water | moisture content to the adsorbent of the 1st adsorption heat exchanger 22a is discharged | emitted from the exhaust port 34a to the outdoor as exhaust air (EA).

<Stacking the outside air processing unit>
According to the stacking platform 50 described above, the outside air processing module 10 can be configured by stacking the outside air processing units 20a to 20d according to the following procedure.

  First, as shown in FIG. 9, the upper frame member 52 is attached to the upper side of each of a plurality (here, four) of the outside air processing units 20a to 20d. Here, the upper frame member 52 is disposed on the upper side of the outside air processing units 20a to 20d, and is fixed to the outside air processing units 20a to 20d by the hanging bolts 59 and the hanging metal fittings 45a to 45d. Therefore, the upper frame member 52 can be attached with the outside air processing units 20a to 20d placed on the floor surface. A reinforcing member 58 is attached to the upper frame member 52 in advance.

  Next, as shown in FIGS. 10 and 11, the upper air processing unit (here, the uppermost air processing unit 20d) with the upper frame member 52 attached is suspended from above by a sling, The lower frame member 55 is attached to the upper frame member 52 and the reinforcing member 58 from below with screws. At this time, the lower frame member 55 is placed on the floor surface, and the upper frame member 52 is easily placed on the lower frame member 55 by lowering the suspension height of the outside air processing unit 20d with the upper frame member 52 attached. It can be mounted on.

  Next, as shown in FIGS. 12 and 13, the upper-stage outside air processing unit (here, the uppermost outside-air processing unit 20d) with the upper frame member 52 and the lower frame member 55 attached is suspended. Until then, the lower frame member 52 is attached to the upper frame member 55 by screwing the lower frame side upper frame member 52 in the state where the lower-stage outside air processing unit (here, the third-stage outside air processing unit 20c from the bottom) is mounted. At this time, the lower-stage outside air processing unit 20c with the upper frame member 52 attached is placed on the floor, and the upper-stage outside air processing unit 20d with the upper frame member 52 and the lower frame member 55 attached is suspended. By lowering the lowered height, the lower frame member 55 on the upper stage side can be easily placed on the upper frame member 52 on the lower stage side. Here, as shown in FIGS. 4 and 6, the upper frame side lower frame member 55 is formed with an insertion hole 57b through which the head of the screw 72 of the lower frame side upper frame member 52 can be inserted. With the head portion of the screw 72 inserted through the insertion hole 57b, the lower frame member 55 on the upper stage side is easily placed on the upper frame member 52 on the lower stage side. Then, the upper air processing unit 20d is supported from below by the lower support bolt 62 and the hanging metal fitting 45d. Here, the work of supporting the upper air processing unit 20d on the upper side by the lower support bolt 62 and the hanging metal fitting 45d is performed when stacking the air processing units of each stage, but is not limited to this. is not. For example, only the operation of fixing the upper frame member 52 to the outside air processing units 20a to 20d with the hanging bolt 59 and the hanging metal fittings 45a to 45d is performed, and the stacking operation of all the outside air processing units 20a to 20d is completed. The upper air processing units 20b to 20d may be supported from below by the support bolts 62 and the suspension fittings 45b to 45d.

  Next, as shown in FIGS. 14 and 15, the upper-stage outside air processing unit (here, the uppermost stage and the third-stage outside air processing unit from the bottom, with the upper frame member 52 and the lower frame member 55 attached). The lower frame member 55 is attached to the upper frame member 52 and the reinforcing member 58 by screwing from the lower side while suspending 20c, 20d). At this time, the lower frame member 55 is placed on the floor, and the upper frame member is lowered by lowering the suspending height of the upper-stage outside air processing units 20c, 20d in a state where the upper frame member 52 and the lower frame member 55 are attached. 52 can be easily placed on the lower frame member 55.

  Thereafter, as shown in FIGS. 16 to 23, in the same manner as the procedures shown in FIGS. 12 to 15, the upper-stage outside air processing units 20 c and 20 d to which the upper frame member 52 and the lower frame member 55 have been attached are The work of attaching the lower-stage outside air processing units 20a and 20b to which the lower frame member 55 and the upper frame member 52 are attached to the lower side while being suspended by the sling is performed at a predetermined level (here, four levels). Repeat until).

  As described above, according to the stacking mount 50, the outside air processing unit 20d on the uppermost side among the plurality (4 in this case) of the outside air processing units 20a to 20d is simply suspended from the upper side by slinging, that is, The plurality of outside air processing units 20a to 20d can be stacked only by performing the work of lifting the outside air processing unit once.

(3) Operation Operation of Outside Air Processing System In the outside air processing system 1 having the outside air processing module 10 configured as described above, the above dehumidifying operation is performed in all the outside air processing units 20a to 20d in response to a command from the remote controller 6. And basic operation of humidification operation. Thereby, a large capacity is realized by connecting a plurality of small capacity outside air processing units 20a to 20d.

(4) Features of the stacking platform and the outside air processing module The outside air processing module 10 configured using the stacking platform 50 and the stacking platform 50 of the present embodiment has the following features.

<A>
According to the stacking platform 50 of the present embodiment, unlike the conventional stacking configuration, it is not necessary to lift the outside air processing units 20a to 20d as the air conditioning unit repeatedly according to the number of stages. The outside air processing units 20a to 20d can be easily stacked.

<B>
According to the stacking platform 50 of the present embodiment, the mounting portion of the upper frame member 52 and the leg member 56 is reinforced by the reinforcing member 58, so that the strength of the stacking platform 50 can be improved.

<C>
According to the stacking platform 50 of the present embodiment, as shown in FIGS. 5, 7, and 8, the reinforcing member 58 can be easily removed as necessary, so that the outside air processing units 20 a to 20 d can be removed. The strength of the stacking platform 50 can be improved without impairing workability such as maintenance.

<D>
According to the stacking platform 50 of the present embodiment, the reinforcing member 58 is attached in advance to the upper side of each of the plural (in this case, four) outside air processing units 20a to 20d during the stacking operation. Since the upper frame member 52 can be attached, the workability of the stacking work can be improved.

<E>
According to the stacking platform 50 of the present embodiment, the upper frame member 52 is attached to the outside air processing units 20a to 20d by using parts unique to the ceiling hanging type outside air processing units 20a to 20d such as the hanging metal fittings 45a to 45d. I am trying to install. That is, in the outside air processing module 10 of the present embodiment, the ceiling hanging type outside air processing units 20 a to 20 d are stacked in a state of being attached so as to be hung from the frame member 51. For this reason, the outside air processing module 10 having a configuration in which the ceiling-suspended outside air processing units 20a to 20d are stacked can be easily realized.

<F>
In the outside air processing module 10 of the present embodiment, the ceiling support type outdoor air processing unit 20b is fixed by fixing the lower support bolt 62 as a lower support member extending upward from each frame member 51 to the suspension fittings 45b to 45d. ~ 20d is also supported from below.

  For this reason, in the outside air processing module 10 according to the present embodiment, the hanging brackets 45b to 45d and the hanging bolt 59 are deformed by suppressing the swinging of the ceiling hanging type outside air processing units 20a to 20d during an earthquake. Can be suppressed.

  Further, the lower support member may be a member other than the lower support bolt 62 as long as it is a member used for fixing to the hanging metal fittings 45 b to 45 d, but the lower support bolt 62 is the same operation as the suspension bolt 59. Since it can fix to the hanging metal fittings 45b-45d, there exists an advantage that the fixing operation | work to the hanging metal fittings 45b-45d can be performed easily. Further, since both the suspension bolt 59 and the lower support bolt 62 are arranged in the vicinity using the long holes 46b to 46d of the suspension fittings 45b to 45d, there is a risk that the fixing work of the lower support bolt 62 may be forgotten. As a result, the workability of fixing work to the hanging metal fittings 45b to 45d is improved.

  Further, in the air conditioning module 10 of the present embodiment, the suspension bolts 59 and the lower support bolts 62 extend from the upper frame member 52, so there is less risk of forgetting to fix the lower support bolts 62, and the suspension fittings 45b to 45d. The workability of the fixing work to the work is improved.

  The present invention can be widely applied to a stacking base for configuring an air conditioning module by stacking a plurality of air conditioning units.
