REFRIGERATING APPARATUS

PURPOSE:To suppress to minimum the decrease and variation of the low pressure side pressure in a refrigeration cycle by a method wherein, when the compressor is actuated the time in which the blower motor the condenser is run at a constant number of revolutions is allowed to agree with the time in which the compressor is tun under delivery control. CONSTITUTION:A refrigeration cycle is formed of a compressor 1, an air cooled condenser 2, a liquid receiver 3, an expansion valve 4, and an evaporator 5 and a control device 7 controls the number of revolutions of a blower 6 for the air cooled condenser 2 on the basis of the temperature of the liquid refrigerant which inputted by a thermistor 8. After the start of the refrigerating apparatus, the temperature of the liquid refrigerant rises gradually (mode e); therefore, to stabilize the operation, the control by the thermistor 8 is stopped and the number of revolutions of the blower 6 is kept constant for a period of time I (mode d); on the other hand, the compressor 1 is kept operating at a constant high pressure side pressure for the identical period of time I from the start of the operation. After an elapse of the time I the number of revolutions of the blower is placed under automatic control based on the temperature detected by the thermistor 8.
