Refrigerator

A refrigeration cycle of a refrigerator according to the present invention is branched into two paths downstream of a first condenser: a cooling path for supplying a refrigerant to an evaporator to generate cold air; and a defrosting path for defrosting by heating the refrigerant and supplying the heated refrigerant to the evaporator, the refrigerant flowing in the cooling path is supplied to the evaporator after passing through the second condenser, and the refrigerant flowing in the defrosting path is heated by exchanging heat with a path for supplying the refrigerant from the compressor to the first condenser. And a heating unit that heats an evaporator thermally coupled to the defrosting path, the refrigerant that dissipates heat in the defrosting path is evaporated in a heating-side evaporator provided downstream of the evaporator and then returns to the compressor, and the flow rate of the refrigerant that flows when switching to the defrosting path is adjusted. 本发明中的冷藏库的制冷循环在第1冷凝器的下游侧分支为两个路径：向蒸发器供给制冷剂以
