To provide a cold storage system capable of cooling by a method decreased in consumption energy.
A duct type cold storage system is formed in such a constitution that a heat exchanger 7 in CO2 piping 10 to form a refrigerating cycle is a heating means to heat water at the internal part of a hot water feeder body 1; a heat-exchanger 17 is a cooling means to cool brine to cool a cold storage agent 26; air cooled through heat exchange with the cold storage agent 26 cooled through operation of the refrigerating cycle and air that is not cooled are mixed together by a damper 29; and air conditioned to a specified temperature is fed to a cold storage box 30 through a duct 28 provided on an inner surface with vapor condensation detecting means S4 and S5.
