Abstract:
To provide a refrigerator capable of suppressing an increase in temperature within the refrigerator and capable of suppressing accumulation of a leaked refrigerant in one place when the refrigerant is leaked.SOLUTION: A refrigerator includes a refrigerating circuit for an inverter, a refrigerating circuit for constant speed, and a control part. The control part stops a compressor of a refrigerating circuit in which a difference between temperature of a condenser and an ambient temperature continues to be between 1 to 3K for six times and operates a compressor of the other refrigerating circuit when the difference between a condenser for an inverter and an ambient temperature at each 30 seconds continues to be between 1 to 3K for six times or the difference between a condenser for constant speed and an ambient temperature at each 30 seconds continues to be between 1 to 3K for six times under a condition in which opening of a heat insulation door is not detected by a thermistor within the refrigerator and the ambient temperature is 50°C or lower.SELECTED DRAWING: Figure 8
