PROBLEM TO BE SOLVED: To sane space of an ineffective volume of a cold storage chamber and to reduce noise of a fan of a chilled gas circulating means for cold storage. SOLUTION: An evaporator 21 for cold storage integrally molded with a heat exchanger for a cold storage chamber 2 and an arbitrary wall for constituting a chilled gas circulating duct 24 is provided to reduce a disposing space of the evaporator 21. A constitution of the duct 24 can be simplified. Further, at the time of normal cooling, the chamber 2 is cooled therein to a predetermined temperature by a natural convection by means of heat exchanging via the evaporator 24 as a rule, and hence noise of a fan of a chilled gas circulating means 25 for cold storage can be reduced. |
