The invention discloses a high-efficiency
ice storage system method. The method specifically comprises the steps of 1, a conventional air-conditioning
refrigeration and ice-making unit combined cold working condition; 2, a conventional air-conditioning
refrigeration and ice-making unit
ice storage working condition; 3, an ice-making unit independent
ice storage working condition; 4, an ice storagedevice independent cold working condition, and 5, a conventional air conditioner and ice storage device combined cold working condition. The invention relates to the technical field of air conditioner ice storage. With the high-efficiency ice storage
system, an auxiliary device is added to help an ice-making coil to be more prone to ice making and de-
icing,
chilled water is utilized to transfer the heat to a
refrigerant or an
ethylene glycol solution through a plate exchanger to realize de-
icing, and the cold capacity released by the ice-making coil during de-
icing is directly absorbed by thechilled water for air-conditioning
refrigeration, so that the refrigerating cold capacity is not wasted; extra heat source for deicing does not need to be additionally added during de-icing, an ice maker works in an ice-making state all the time, and the conversion is not needed; and the ice-making amount is large, the efficiency is high, the
cold storage capacity per unit capacity of an ice storage device is large, and the cold capacity released during de-icing can be stored as needed.
