Japanese Patent JP2889602
Kind Code:
B2
Abstract:
PURPOSE:To maintain the interior of a storage warehouse to set temperature during freezing a cold storage agent by directing cold air cooled by the cold storage agent to a cold air circulation passage for forcedly circulating the cold air to a storage chamber and to a cold air bypass passage for feeding back the cold air to an evaporator. CONSTITUTION:A first control part 41 controls operation and stop of a compressor driving motor 34, and a second control part 53 control operation and stop of a fan device 11B. Since cold air cooled by a cold storage agent 12B is directed to a cold air circulation passage C for forcedly circulating the cold air to a storage chamber 8 and to a cold air bypass passage B for feeding back the same to an evaporator 10, the storage chamber 8 can be cooled during freezing of the cold storage agent 12B. Further, since the first and second control parts 41, 53 are operated at a first temperature set by a temperature setting part 52 and at a second temperature higher than the first one or at a third temperature higher than the second one, the temperature inside a freezing chamber 7 can be controlled by the first control part 41 and temperature inside the storage chamber 8 can be controlled by the second control part 53.
