Title:
REFRIGERATOR
Document Type and Number:
WIPO Patent Application WO/2020/121404
Kind Code:
A1
Abstract:
This refrigerator is provided with: a refrigerant circuit which is provided with a compressor, a flow passage switching device, a machine room condenser, a surface condensing tube, a dew condensation preventing tube, a depressurizing device, and a cooler, and through which a refrigerant circulates; a ambient humidity sensor for detecting the ambient relative humidity; and a control device for controlling the flow passage switching device. When the relative humidity detected by the ambient humidity sensor is lower than a preset reference value, the control device switches the flow passage switching device such that a refrigerant flows in a normal flow state in which the refrigerant flows through in the order of the compressor, the flow passage switching device, the machine room condenser, the surface condensing tube, and the dew condensation preventing tube; and when the relative humidity detected by the ambient humidity sensor is no less than the reference value, the control device switches the flow passage switching device such that a refrigerant flows in a reverse flow state in which the refrigerant flows through in the reverse order of the compressor, the flow passage switching device, the dew condensation preventing tube, the surface condensing tube, and the machine room condenser.
