The invention belongs to the technical field of evaporator defrosting and discloses a refrigerating circulatory system which comprises a compressor, condenser and an evaporation assembly sequentially connected in the same closed loop through a pipeline; the evaporation assembly comprises a first evaporation unit and a second evaporation unit; the first evaporation unit and the second evaporation unit can switch over along three working conditions namely both the first evaporation unit and the second evaporation unit operate normally, the first evaporation unit works and the second evaporation unit defrosts, or the first evaporation unit defrosts and the second evaporation unit works. According to the invention, two evaporation units are adopted to switch over along three working conditions, and the self structure is utilized to realize the defrosting function without halt. The refrigerating circulatory system uniformly divides the original evaporator into two evaporators without increasing the evaporator area, part of pipelines and a control valve are additionally arranged, defrosting without halt is realized, continuous refrigeration can be realized during the defrosting process, the defrosting operation on the evaporator can be realized without additionally providing auxiliary equipment, and the defrosting function is realized without consuming energy additionally.
