PURPOSE:To improve a heat-exchange rate, and to obtain the air-conditioning ventilating fan provided with forced simultaneous air-supply and exhaust ventilation passing no heat-exchange element and the function of a circulator by operating the heat-exchange element at time intervals required and replacing ventilation flues for exhaust and air-supply in the heat-exchange element. CONSTITUTION:A louver 5 with an indoor-side suction port 6 and a discharge port 7 is fitted to the front of a main body 1 with an outdoor-side suction port 2, a discharge port 3 and a parting plate 4, and the cubic columnar heat-exchange elements 8 formed by alternately laminating heat-transfer plates and space plates are mounted at positions adjacent to the louver 5 in the main body 1. Partition plates 13a-13d, 14a-14d are each formed to the main body 1 and the louver 5 at positions being in contact with each angle of the heat-exchange elements 8, and the heat-exchange elements 8 are turned through a shaft 9 at every fixed time at the intervals of 90 deg. by a motor 10. Blowers 15, 17 for exhaust and air-supply driven by a motor 19 are installed into each left and right chamber partitioned by the parting plate 4 in the main body 1. |
