Abstract: A drive torque estimation device secures accuracy of a drive torque of a compressor by accurately grasping a flow rate of refrigerant in a cycle. The pressure difference is detected by a condenser as a resistor for calculating the flow rate. The pressure difference between two portions based on physical quantities relating to refrigerant pressures is detected using first and second sensors arranged at two portions in the cycle. A flow rate is calculated based on the detected pressure difference. The first sensor may be an upstream-side pressure sensor arranged at an inlet of the condenser or at a high-pressure side pipe upstream of the inlet and detects a pressure of the refrigerant flowing therethrough, and the second sensor may be a downstream-side pressure sensor arranged at a gas/liquid mixed phase region of the condenser and detects a pressure of the refrigerant flowing therethrough or may be a temperature sensor.
