A refrigerating apparatus executing the redistributing operation of refrigerant when the actual suction pressure of a compressor is lower than a suction pressure lower limit value. The suction pressure lower limit value is varied in response to the condensation temperature of refrigerant which varies in accordance with the actual temperature in the vicinity of a condenser. When the condensation temperature of refrigerant is greater than a predetermined comparison value, a first limit value is selected as the suction pressure lower limit value. Otherwise, a second limit value less than the first limit value is selected. The refrigerating apparatus may be controlled in accordance with the selected suction pressure lower limit value.
