Abstract

PURPOSE: To reduce noises with a simple structure by a method wherein a quiescent time is provided when a fan for conducting air discharge, air suction of a heat exchanging element changes over reversible rotation.
CONSTITUTION: A motor 5 is of a capacitor induction type, is connected from both ends of the capacitor 9 to a timer 10, and by means of automatic inversion of the timer rotates normally at a terminal (a) rotates inversely at a terminal (b). In the operating cycle of this timer 10 its cyclic operating time S0 is composed of the operating time S1 of the terminal (a), the operating time S2 of the terminal (b) and a quiescent time ▵S. In the result, when a quiescent time is inserted between each operating time in changing times of the reversible rotation of the fan and the fan is stopped in non-braking, noises can be reduced.
