摘要： A device executing a start-up control method for an electric scroll compressor has a thermistor (18) and a pressure sensor (20) which, prior to the start-up of the scroll compression unit, detect temperature and pressure of a suction refrigerant introduced into the compression unit (2), and a controller (10) for controlling driving of a motor (4) of the compression unit (2) at the start-up of the compressor. The controller (10) determines at the start-up of the compressor whether or not a liquid refrigerant exists in the compression unit (2) on the basis of the detected temperature and pressure; selects either a normal start-up mode or a liquid-discharge mode in which the rotational speed of the motor (4) is regulated to be lower than in the normal start-up mode, according to the determination result; and controls the start-up of the compression unit (2) through the motor (4) according to the selected mode.

摘要： An inverter-integrated electric compressor has a control device. The control device estimates a compressor suction pressure based on the temperature of the power element of the inverter, or directly measures the compressor suction pressure by a sensor, or estimates the compressor suction pressure based on a compressor suction temperature or on a compressor housing temperature. Further, the control device calculates a motor torque based on a motor rotational speed, a motor phase current, and a motor phase voltage, estimates a compressor discharge pressure based on the compressor suction pressure and the motor torque, and estimates a compressor discharge temperature based on the compressor suction pressure and the compressor discharge pressure. The electric compressor has a discharge temperature detection device in place of a conventional thermal protector.

The partition wall is located between an electric motor-storing section, which stores the electric motor and in which lubricating oil-containing fluid to be compressed is present, and a circuit section for supplying electricity to the electric motor. The terminal member extends through the partition wall in a sealed and insulated manner. An electricity conduction wire at an end of a lead wire for supplying electricity to the electric motor is directly connected to the end of the terminal member which is on the electric motor-storing section side. An insulation cover is provided so as to extend from the electric motor-storing section—side end of the terminal member to an insulation cover tube of the electricity conduction wire of the lead wire for supplying electricity to the electric motor. The terminal device can exhibit high insulation performance even if polyalkylene glycol-based oil is used as lubricating oil-containing fluid to be compressed. Further, the terminal device has a simple structure not requiring a cluster, can ensure high insulation performance, and can be constructed at low cost.
