Abstract

In a motor lock determination device (), a lock determination on an electric motor () is performed such that: a first detection value (PI), which is a detection value (P) of a refrigerant pressure sensor () during a stop of an electric fan (), is detected, and a second detection value (P), which is a detection value (P) of the refrigerant pressure sensor () after the electric fan () is driven for a first predetermined time (Δ), is detected; when the second detection value (P) 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 (P) is less than the first detection value (PI), it is determined that no motor lock occurs.
