    摘要: A refrigerating cycle apparatus including an inverter driven compressor with controllable speed of rotation, a four-way valve, an indoor heat exchanger, a pressure reducing device, outdoor heat exchanger, a defrosting condition detector for detecting a frosting state of the outdoor heat exchanger in a heating operation, a defrosting operation controller for carrying out a defrosting operation based on a detection signal from the defrosting condition detector and having a minimum operable frequency controller for controlling a minimum operable frequency for the compressor on restarting after completion of the defrosting operation and/or a starting speed controller for controlling a starting speed for the compressor based on a detection signal from the defrosting condition detector on restarting after completion of the defrosting operation in order to provide proper lubrication after a defrost operation.
