The second refrigerant circulation circuit is provided with a regenerator to be cooled by the second refrigerant circulation circuit, and the second refrigerant circulation circuit is arranged in parallel with the first refrigerant circulation circuit and has a second heat exchange pipe on the upstream side and a second capillary tube on the downstream side in series. The heat exchange pipe is arranged so that the refrigerant passing through the pipe is further cooled by the cool storage agent, and the first refrigerant circulation circuit performs normal cooling operation and cools the cool storage agent, and the subsequent switching A refrigerator characterized in that the second refrigerant circulation circuit performs a quick freezing operation accompanied by cooling by the regenerator. (2) Request for utility model registration in which the continuous operation time of the compressor in the first refrigerant circulation circuit after the end of the quick freezing operation in the second refrigerant circulation circuit is determined in advance by a timer in the attached microcomputer. Refrigerator according to item 1 of the range. (3) The continuous operation time of the compressor in the first refrigerant circulation circuit after the quick freezing operation in the second refrigerant circulation circuit has been completed is detected by an attached temperature sensor that is in contact with the refrigerant. The refrigerator according to claim 1 of the utility model registration, wherein the time period is set until the temperature at that time becomes below the freezing point of the cold storage agent.
