<p>PURPOSE:To obtain an extremely low noise type air conditioner capable of being formed compactly by providing a bypass air blow passage, which allows an air stream to freely flow by switching, between a U-shaped air blow passage and an air blow passage for communication of an air port to an outdoor exhaust port and disposing a total heat exchanger, a fan for blowing air, a fan for circulating air, etc. in the respective air blow passages. CONSTITUTION:A substantially U-shaped air blow passage A is provided for communication of an external air inlet port 1 to an indoor air outlet port 2, and if necessary, a total heat exchanger 5, a fan 6 for blowing air, an electric motor 7, a controlling device 8, a noise deadening device 9, a main filter 10, etc. are disposed in the air blow passage A. Further, the air blow passage a is additionally provided with an air blow passage B for communication of an air port 3 for the indoor air with an exhaust port 4, and a circulating air port filter 10', a fan 11 for circulated air, an electric motor 12, etc. are disposed in the air blow passage B. Furthermore, an air blow bypass passage C is provided between both air blow passages A, B, and a switching damper mechanism 13 is adapted in the air blow passage C to exhaust the total amount of air circulated from the indoor side or to bypass-circulate a portion of such circulated air into the air blow passage A.</p> |
