度制御装置。 An electronic expansion valve for an air conditioner, which is used to reduce the pressure of refrigerant in an air conditioner, and includes a pulse motor 9 and a valve body 12 that is driven by the pulse motor 9 and adjusts the opening degree of a refrigerant passage 10. When the harmonizer starts operating, the pulse motor 9
an initial valve opening control means 16 that outputs a command to move the valve body 12 by a predetermined amount in the valve opening direction; a fully closing operation control means 17 that outputs a command to the pulse motor 9 to fully close the valve body 12; and the fully closing operation control means 17.
The pulse motor 9 issues a command to maintain the initial setting opening of the valve body 12, which has been fully closed by the
1. An opening degree control device for an electronic expansion valve for an air conditioner, characterized in that an opening degree control device for an electronic expansion valve for an air conditioner is attached.
