Abstract: PROBLEM TO BE SOLVED: To provide a constitution of an evaporator which reduces the excess refrigerant retained in an accumulator part of the evaporator and improves the safety in leakage of the refrigerant, in a refrigerator using the combustible refrigerant. SOLUTION: This refrigerator 1 using the combustible refrigerant comprises an evaporator 18, an outlet pipe 18d mounted across an air trunk of the evaporator 18, and an accumulator 18e connected to the outlet pipe 18d and storing the liquid refrigerant. As a result, temperature of the outlet pipe 18d is kept higher than evaporation temperature with the proper amount of refrigerant, the residual refrigerant retained in the accumulator 18e is reduced, and further the accumulator 18e is miniaturized, which reduces the input of a defrosting heater, and improves the safety in leakage of the refrigerant.

Abstract: 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.
