PROBLEM TO BE SOLVED: To enhance accuracy for estimating torque at activation, in a torque estimation device of a gas compressor.SOLUTION: A torque estimation device 100 of a gas compressor 200 comprises: a reference torque characteristic storage part 20 which stores a reference torque characteristic as a torque characteristic of the gas compressor 200 in a specified operation state of the gas compressor 200; a torque setting part 10 which sets torque corresponding to an inputted rotational speed of the gas compressor 200, and the pressure of a refrigerant discharged from the gas compressor 200 on the basis of the reference torque characteristic which is stored in the reference torque characteristic storage part 20; and a torque correction part which sets torque at the activation of the gas compressor 200 out of the torque which is set by the torque setting part 10 by correction corresponding to the rotational speed with respect to the torque which is set by the torque setting part 10, and a lapse time after the activation.SELECTED DRAWING: Figure 1 |
