Title:
EXPANSION VALVE DEVICE
Document Type and Number:
WIPO Patent Application WO/2013/042303
Kind Code:
A1
Abstract:
A drive control device (10) performs, at a constant current, mode switching between a first mode in which the degree of opening of a refrigerant path (51a) is changed in a first flow rate range in which the flow rate of a refrigerant flowing through the refrigerant path (51a) is less than or equal to a predetermined flow rate, and a second mode in which the degree of opening of the refrigerant path is changed in a second flow rate range in which the flow rate of the refrigerant flowing through the refrigerant path exceeds the predetermined flow rate. A constant current value (A2) at which mode switching is performed is increased by the drive control device to a value greater than a constant current value (A1) at which the degree of opening of the refrigerant path is changed at the constant current in the first mode.
