Title:
REFRIGERATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/162776
Kind Code:
A1
Abstract:
According to the present invention, when the current time is included in a predetermined time slot, a control device (3) initiates defrosting operation on the basis of the blow-out temperature of air in an indoor heat exchanger (21) and the evaporation temperature of a refrigerant in the indoor heat exchanger (21) during cooling operation, measures the electric current value of an air blower (22), and sets the measured electric current value as a defrosting initiation threshold. The control device (3) initiates defrosting operation on the basis of the electric current value of the air blower (22).
