とを特徴とする保冷庫。 A refrigeration cycle is constructed by sequentially connecting a cold storage chamber for storing objects to be cooled, a compressor, a four-way valve, a first heat exchanger, a throttle, and a second heat exchanger, and a blower for the first heat exchanger and a second heat exchanger. Equipped with an exchanger blower,
a cooling unit that performs defrosting using a reversible cycle; and a first cooling unit that is connected between the cold storage chamber and the cooling unit and that circulates air in the cold storage chamber through the first heat exchanger using the first heat exchanger blower.
A second system path is formed in which the air in the cold storage chamber is circulated through the second heat exchanger by the system path and the second heat exchanger blower, and each system path is provided with the first and second heat exchanger. A cold storage warehouse comprising a duct provided with a damper that cuts off a line on the heat exchanger side that functions as a condenser during cooling operation and defrosting operation from the cold storage chamber and communicates it with the outside air.
