Abstract
PURPOSE: To prevent cool air from blowing out during defrosting operation, by connecting an auxiliary electric heater for heating to star-delta connection circuits, and by operating an air conditioner by a star connection during heating and by a delta connection during defrosting.
CONSTITUTION: The auxiliary electric heater 27 is connected to a contact point 25 between the contact (52H)6 of an electromagnetic contactor and an exciting coil (42H)24, and also to star-delta connection circuits. When the low temperature side L of a temperature adjuster 22 is in an ON condition, a contact 29 is closed by an exciting coil X2 being excited, an exciting coil 52H is energized, a contact (52H)6 is closed, and an auxiliary electric heater 27 is functioned to heat by a star connection. During defrosting operation, on the other hand, an exciting coil X2 is energized by a timer switch 26, a contact 29 is opened, while a contact 28 is closed, an exciting coil 42H is energized to close a contact (42H)25 and to open a contact (52H)6, and an auxiliary electric heater 27 is operated by a delta connection.
