Description
technical field [0001] The invention relates to the technical field of refrigeration equipment, in particular to a refrigeration unit, an ice storage system and an operation method of the refrigeration unit. Background technique [0002] At present, there are various types of refrigeration equipment. Taking conventional ice storage systems and conventional chillers as examples, both of them have certain problems under different working conditions. [0003] In the conventional ice storage system, the chiller usually uses ethylene glycol solution as the refrigerant. In the case of ice making, the ethylene glycol solution lower than the freezing temperature of water is sent to the relevant ice storage equipment for ice making. The freezing point of the ethylene glycol aqueous solution is low, which can be beneficial to ensure the stable operation of the unit under the ice making condition. However, when the conventional ice storage system works under refrigeration conditions,...
