Refrigerator

A refrigeration cycle of a refrigerator according to the present invention branches downstream of a first condenser into the following two passages: a cooling passage for supplying a refrigerant to an evaporator to generate cold air; and a defrosting passage that heats the refrigerant and supplies the heated refrigerant to the evaporator to defrost, the refrigerant flowing through the cooling passage is supplied to the evaporator after passing through the second condenser, and the refrigerant flowing through the defrosting passage is heated by exchanging heat with a path through which the refrigerant is supplied from the compressor to the first condenser. The evaporator thermally coupled to the defrosting passage is heated, and the refrigerant that dissipates heat in the defrosting passage is evaporated in the heating-side evaporator provided on the downstream side of the evaporator and then returned to the compressor. 本发明的冷藏库的制冷循环在第1冷凝器的下游侧分支为以下两个通路：向蒸发器供给制冷剂以生成冷气的冷却通路；和通过加热制冷剂并将加热后的制冷剂供给至蒸发器而进行除霜的除霜通路，流经冷却通
