PURPOSE:To locate a packing, interposed between a main body and a fan casing, correctly and prevent the positional deviation of the packing by a method wherein the fan casing, arranged in the main body, is formed with stepped parts at the corners thereof. CONSTITUTION:An indoor side chamber (a) accommodates an indoor side heat exchanger 50 corresponding to a suction port 23 and an outdoor fan 51 corresponding to a delivery port 24 respectively. An outdoor side chamber (b) accommodates an outdoor side heat exchanger 57 corresponding to a suction port 56 and an outdoor fan 59 corresponding to the delivery port 58 respectively. The outdoor fan casing 62 is formed with the stepped part 63 at the corner thereof and the packing 64 is adhered to the stepped part 63. The outdoor fan casing 55 is also formed with the stepped part 65 at the corner thereof and the packing 66 is adhered to the stepped part 65. When a ceiling plate is put on the casings, the lower surface of the ceiling plate is abutted against the packings 64, 66 and sealing between the casings 55, 62 and the ceiling plate may be effected surely. |
