PURPOSE:To make uniform the temperature of air conditioned space and simplify the construction by attaching both functions of drawing ventilation function and one that gives a spiral component to the air supplied to a drawing ventilator. CONSTITUTION:By the rotation of rotary vanes 6 attached to a rotor 3 which is interlocked with a motor 5, the air in the air conditioned space is drawn from an inlet 2. As it passes through a heat exchanger 4, the temperature regulated to a desired level, and then, by being given a spiral component due to the rotation of the rotary vanes 6 and a downwardly expanding component due to a downwardly expanding vane 7, spiral downwardly expanding air flows A, B, C, D are formed. Therefore, the blown air hardly hits directly the human body or objects to be air conditioned. Thereby, a uniformly air conditioned space is obtained, and since the drawing ventilator has both the functions of drawing ventilation function and one that gives the spiral component to the blown air, the construction can be simplified. |
