の劣化防止とケーシング２６の強度の向上ができる。In the air conditioner configured as described above, when ventilation is performed as in the conventional case, the air supply blower 34 and the exhaust air blower 35 are operated to supply the air supply air from the outdoor suction port 20. Passing through the passage 23, the heat exchanger 3
After passing through 6, the air is blown in through the suction port (not shown) of the air supply blower 34 and is blown out through the indoor-side outlet 19. Further, the exhaust flow is sucked from the suction port (not shown) of the exhaust blower 31 through the exhaust passage 24 from the indoor suction port 18, the heat exchanger 36, and is blown out from the outdoor air outlet 21. On this occasion,
At the same time, by the heat exchanger 36 where the air supply flow and the exhaust air flow intersect,
Sensible heat and latent heat are exchanged between the air supply flow and the exhaust air flow to prevent an increase in heat load of cooling and heating due to ventilation. In this case, the sound emission of the air flow generated by the operation of the air supply blower 34 and the exhaust air blower 35 is achieved by directly attaching the sound absorbing material 30 to the casing 26 due to the noise damping effect of the air layer in the space 31 provided in the casing 26. Compared with the case, it exhibits sound absorption characteristics in the low frequency region, and noise reduction can be achieved. Furthermore, the provision of the guide ribs 29 facilitates the attachment of the sound absorbing material 30, preventing deterioration of the sound absorbing characteristics due to variations in the shape of the air passage and improving the strength of the casing 26.
