Abstract: PROBLEM TO BE SOLVED: To provide a cooling storage securing safety in applying combustible refrigerant and improving the reliability of a cooling system in a manufacturing method for the cooling storage. SOLUTION: This cooling storage using the combustible refrigerant for the cooling cycle is manufactured by a leakage inspection process 2 applying a gas pressure of 1 MPa or more to the inside and inspecting the leakage of the cooling cycle, a refrigerant sealing process 3 sealing the combustible refrigerant after finishing the leakage inspection process 2, and a sealing process 4 sealing a pipe after the refrigerant sealing process 3.

Abstract: PROBLEM TO BE SOLVED: To provide a refrigerator enabled of easily executing the piping work of inserting piping such as suction pipe into an inner box and forming the piping. SOLUTION: The ineffective space of a condenser chamber for refrigeration 20 in the longitudinal direction can be reduced by securing the size of the piping by inserting the refrigerant pipe 33 of the final piping form of a reverse U shape into a long hole 35 arranged to an inner box 11 and fitting the refrigerant pipe 33 into a take out hole 36, and reducing the dispersion of the piping size.
