Title:
室外機、空気調和装置および空気調和装置の運転制御方法
Document Type and Number:
Japanese Patent JP7317108
Kind Code:
B2
Abstract:
An outdoor unit includes a heat exchanger, a fan having a motor having coils to blow air to the heat exchanger, a connection switching unit to switch a connection state of the coils between a first connection state and a second connection state in which a line voltage is lower than a line voltage in the first connection state, and a temperature sensor to detect a temperature. When the motor is not driven, the connection switching unit sets the connection state of the coils to the second connection state. When the motor rotates, the connection switching unit sets the connection state of the coils to the first connection state if a detected temperature by the temperature sensor is higher than or equal to a threshold, and the connection switching unit sets the connection state of the coils to the second connection state if the detected temperature is lower than the threshold.
