<p>In a motor lock determination device (1), a lock determination on an electric motor (7) is performed such that: a first detection value (PI), which is a detection value (P) of a refrigerant pressure sensor (17) during a stop of an electric fan (5), is detected, and a second detection value (P2), which is a detection value (P) of the refrigerant pressure sensor (17) after the electric fan (5) is driven for a first predetermined time (Δίΐ), is detected; when the second detection value (P2) is equal to the first detection value (PI) or more than the first detection value (PI), it is determined that a motor lock occurs; and when the second detection value (P2) is less than the first detection value (PI), it is determined that no motor lock occurs.</p> |
