摘要：To provide a refrigeration device in which a defrosting operation is hardlyexecuted, in a situation where a heating operation is easily executed continuously or it isdesirable that the heating operation is executed continuously.SOLUTION: A refrigeration
device includes: a refrigerant circuit (6) in which a compressor (8), an outdoor heatexchanger (11), an expansion valve (12) and an indoor heat exchanger (32) are connectedand which can at least execute a heating operation by circulating a refrigerant; and acontrol part (9) which starts a defrosting operation for melting frost attached to theoutdoor heat exchanger (11) in the case where a first defrosting start condition issatisfied in the case where a predetermined precondition is not satisfied, and which startsa defrosting operation in the case where a second defrosting start condition whosecondition is stricter than the first defrosting condition is satisfied in the case where thepredetermined precondition is satisfied. The predetermined precondition is satisfied atleast in one case out of: a situation where attachment of frost in the outdoor heatexchanger (11) hardly progresses; and a situation where a load on a heating operation islarge.SELECTED DRAWING: Figure 3
