The humidifier 62 is provided on the downstream side of the flow of the outside air of the indoor heat exchanger 61. The humidifier 62 absorbs water by a humidifying element (not shown) having high water retention and allows the outside air to pass through the humidifying element. Humidify the outside air.
The humidifier 62 is provided with a humidifier control box 68 having a water supply connection port 67. In the humidifier control box 68, a depressurization for reducing the pressure of water supplied from the water supply connection port 67 to a predetermined pressure. A valve, an electromagnetic valve that opens and closes to supply the decompressed water to the humidifying element, and a control board that controls the operation of the electromagnetic valve are provided. In the present embodiment, the humidifier control box 68 is provided on the side panel 11c of the housing 11 located on the inspection ports 20 and 20 side as shown in FIG.
The side panel 11c is provided with a drain pipe connection port 69 for discharging drain water received by the drain pan 63 to the outside below the side panel 11c. The drain pipe connection port 69 is connected to a drain pipe when drain water is naturally drained from the drain pan 63. In addition, the code | symbol 70 is also a drain pipe connection port, and this drain pipe connection port 70 is used when draining from the drain pan 63 using a drain pump. When this drain pipe connection port 70 is used, the drain pipe connection port 69 for natural drainage is sealed.

  In this embodiment, the side panel 11c of the housing 11 is provided with a detachable maintenance panel 22 at a position corresponding to the total heat exchange element 31, as shown in FIG. Further, as described above, the total heat exchange element 31 has the side portions of the total heat exchange element 31 supported by the four rail members 37 </ b> A to 37 </ b> D arranged in the housing 11.

After being sucked into the housing 11 from 12, it is discharged to the outside as exhaust EA from the outdoor outlet 15 through the discharge path 34. On the other hand, by driving the air supply fan 33, the outside air OA is sucked into the housing 11 from the outdoor side suction port 14, then reaches the total heat exchange element 31 through the introduction path 35, and this total heat exchange element At 31, heat is exchanged with the inside air RA. The heat exchanged outside air OA reaches the air conditioning unit 60, is cooled or heated by the indoor heat exchanger 61 of the air conditioning unit 60, and is further humidified by the humidifier 62 as necessary. It is supplied indoors as air supply SA from the air outlet 13.
When the room temperature is lower than the outside air temperature during the heating operation, or when the room temperature is higher than the outside air temperature during the cooling operation, the damper plate 81 of the damper unit 80 closes the exhaust opening 17b and opens the bypass opening 17c. In this state, after the indoor air RA is sucked into the housing 11 from the indoor suction port 12, it passes through the total heat exchange element 31 and the bypass path 39 that does not pass through the outdoor air outlet 15 as exhaust EA. To be discharged. For this reason, the air conditioning load of the air conditioning unit 60 can be reduced, and resource saving and energy saving can be achieved.

Next, the air path formation body 36 is demonstrated.
FIG. 5 is an exploded perspective view of the air passage formation body 36, and FIG. 6 is a perspective view when the air passage formation body 36 is accommodated in the housing 11.
The air path forming body 36 is formed by combining a plurality (five in this embodiment) of members made of a foamed resin material. Specifically, the outdoor-side lower member 101 disposed on the outdoor side of the total heat exchange element 31, the outdoor-side upper member 102 disposed on the outdoor-side lower member 101, and the indoor side of the total heat exchange element 31. The indoor side lower member 103 arranged, the indoor side upper member 104 arranged above the indoor side lower member 103, the outdoor side lower member 101 and the indoor side lower member 103 located beside the total heat exchange element 31. And a connecting member 105 that forms a part of the above-described bypass path 39, and is formed by combining these members. For this reason, compared with the conventional one, the number of parts is greatly reduced, the number of assembling steps is reduced, and the manufacturing cost is greatly reduced. Further, as shown in FIG. 2, the air path forming body 36 forms an outside air suction path 38a, an inside air suction path 38b, an exhaust path 38c, and an air supply path 38d, and functions as a heat insulating material. The outside air processing air conditioner 10 is provided that realizes weight reduction and is easy to assemble, as compared with the one in which various heat insulating materials are bonded to a sheet metal.

The air guide opening 103b is provided at a position facing the air guide opening 101b of the outdoor-side lower member 101 through the total heat exchange element 31, and is formed to have substantially the same size as the air guide opening 101b. .

  Thus, in this structure, since the air path formation body 36 is arrange | positioned left-right symmetrically with respect to the total heat exchange element 31, the exhaust opening 103c which inhales internal air, and the air supply opening 101a which inhales external air are symmetrical. The inside air and the outside air sucked from the exhaust opening 103c and the air supply opening 101a are blown over the entire width of the total heat exchange element 31 through the air guide openings 103b and 101b formed in a symmetrical shape. Is done. For this reason, the air volume distribution between the outside air OA blown to the total heat exchange element 31 via the air path formation body 36 and the inside air RA blown to the total heat exchange element 31 via the air path formation body 36 is substantially the same. Can be made. Therefore, for example, the air volume of the outside air OA increases at a portion where the air volume of the inside air RA is large, and the air volume of the outside air OA decreases at a portion where the air volume of the inside air RA is small, so that the heat exchange efficiency in the total heat exchange element 31 is improved. .

On the other hand, the indoor-side lower member 103 and the indoor-side upper member 104 are provided with partition walls 103e and 104A that divide the opening 103a into right and left of the exhaust opening 103c and the bypass opening 103d. A bypass path 39 is formed between 104 and the side panel 11 d of the housing 11.

Since the air supply fan 33 is disposed in the inner concave portion 36A and the exhaust fan 32 is disposed in the outdoor-side concave portion 36B, the air supply fan 33 and the exhaust fan 32 can be accommodated in the housing 11 in a compact manner, and the outside air processing is performed. The size of the air conditioner 10 can be reduced.

  Further, according to the present embodiment, the air supply fan 33 and the exhaust fan 32 are respectively mounted with the fan motors 32A and 33A toward the same side panel 11c of the housing 11, and therefore, from the side panel 11c side. Both fan motors 32A and 33A can be accessed, and maintenance work of the fan motors 32A and 33A can be easily performed.

  Moreover, according to this embodiment, since the air path formation body 36 is provided with the rail members 37C and 37D which support the total heat exchange element 31 so that insertion / extraction is possible in the width direction of the housing | casing 11, in this rail member 37C and 37D, The total heat exchange element 31 can be easily exchanged by attaching and detaching the total heat exchange element 31 along the line.

  Further, according to the present embodiment, in the introduction path 35, the indoor heat exchanger 61 that performs heat exchange between the air flowing through the introduction path 35 and the refrigerant is arranged on the outside air outlet side of the total heat exchange element 31. Therefore, the outdoor air heat exchanged by the total heat exchange element 31 can be further cooled or heated by the indoor heat exchanger 61 and supplied indoors.

  As mentioned above, although this invention was demonstrated based on the said embodiment, this invention is not limited to this. For example, in the present embodiment, the total heat exchange element 31 is divided into two and accommodated in the housing 11, but is not limited thereto. Further, when the width (capacity) of the total heat exchange element 31 may be smaller than the width of the housing 11, a spacer formed in the shape of a square column with foamed resin is disposed on the side of the total heat exchange element 31. May be.
