Title:
空調装置
Document Type and Number:
Japanese Patent JP4479275
Kind Code:
B2
Abstract:
An air-conditioning system includes a refrigeration cycle and a control unit. The refrigeration cycle includes an electric compressor in which a compression mechanism for drawing a refrigerant therein for compression is integrated with an electric motor for driving the compression mechanism, and a motor drive circuit for driving the motor is cooled using an intake refrigerant drawn into the compression mechanism. The control unit provides operational control to the motor drive circuit and the refrigeration cycle. When the temperature of the motor drive circuit has exceeded a predetermined temperature, the control unit varies a condition of supplying air to exchange heat with the refrigerant flowing through the refrigeration cycle to thereby reduce the temperature of the intake refrigerant.
