Abstract
Freezing is prevented when either of two blow ports of a bidirectional blow air-conditioner is closed. A first blowing fan is disposed on one of the sides of a heat exchanger on the utilization side and a second blowing fan is disposed on the other side. First and second blow ports are so disposed as to correspond to these showing fans, respectively, and a flap is operable to close the first blow port. The blow quantity of the second blowing fan, when the flap closes the first blow port, is controlled to a value greater than the blow quantity of the second blowing fan when the flap does not close the first blow port.
