Abstract

A drive torque calculation device for a compressor applied to a refrigerating cycle formed by a compressor, a heat radiator, an expansion device and an evaporator which are connected to each other in this order calculates the drive torque of the compressor with use of a calculation expression including, as a variable, the mass flow quantity of a refrigerant passing through the expansion device.
