<p>When the temperature detected by a coolant temperature sensor (65) during heating operation is below a threshold value and it is determined that frost has formed on the outdoor heat exchanger (16) and the answer in (S110) is YES, an electronic control device (50) reduces the airflow blown out from an electric fan (32) in (S120). Therefore, the airflow passing through a heating heat exchanger (13) and blown out from openings (37a, 37b, 37c) is reduced. Consequently, when the heating heat exchanger is heating the internal air using high temperature high pressure coolant and frost has formed on the outdoor heat exchanger, the airflow passing through the heating heat exchanger can be reduced. As a result, the reduction in the temperature of the air blown out from the heating heat exchanger can be limited.</p> |
