Title:
EXPANSION VALVE DEVICE
Document Type and Number:
Japanese Patent JP2016169893
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an expansion valve device which measures a flow rate with high accuracy and enables downsizing.SOLUTION: In an expansion valve device 10, a first temperature sensor 31a and a first pressure sensor 31b are provided in a first refrigerant passage 21 of a housing 20. A second temperature sensor 32a, a second pressure sensor 32b, and a third pressure sensor 33b are provided in a second refrigerant passage 22 of the housing 20. An ECU 15 calculates a refrigerant flow rate and a degree of superheat of a refrigerant passing through the first refrigerant passage 21 by using values detected by the respective sensors 30.SELECTED DRAWING: Figure 1
