  "textContent": "This air conditioning device for a vehicle comprises: an indoor condenser (14); an indoor evaporator (13); a first expansion valve (22); a second expansion valve (23); a refrigerant line (40); an expansion valve control detector (30); and a controller (50). The expansion valve control detector (30) is constituted by: only one temperature sensor (31) that detects the temperature of refrigerant in an inter-expansion valve line (44) of the refrigerant line (40); and only one pressure sensor (32) that detects the pressure of the refrigerant in the inter-expansion valve line (44). During a cooling operation, the controller (50) issues, to the first expansion valve (22), an opening command corresponding to a state quantity of the refrigerant that has been detected by the expansion valve control detector (30), and during a heating operation, the controller issues, to the second expansion valve (23), an opening command corresponding to a state quantity of the refrigerant that has been detected by the expansion valve control detector (30).",
