COLD HEAT REGENERATING TYPE CHILLING UNIT

摘要

PROBLEM TO BE SOLVED: To suppress securely the deformation of an evaporator tube for cold heat regeneration caused by the volume expansion of a cold heat regenerating material at the freezing of it. SOLUTION: Cold heat regenerating packs 23 that are filled with a cold heat regenerating material are arranged between the rows of the tubes 10a of an evaporator 10 for the heat regeneration and a gap holding stay 30 that hold the intervals of the rows of the tubes 10a at a predetermined distance is mounted on the evaporator 10 for the cold heat regeneration. The force of expanding tubes that is generated by the volume expansion of the cold heat regenerating material at the freezing of it is stopped by the stay 30 and the increase of the distances between the rows of the tubes 10a is prevented and the deformation of the evaporator tubes for the heat regeneration is suppressed securely.
