Abstract

The invention relates to the field of ice storage, in particular to an ice-storage air conditioner and an ice-storage method. Ice making and ice stripping are carried out in a circulation manner, and therefore energy efficiency and the icing rate of a system can be improved. The defects that in the prior art, a coil pipe is adopted to heat exchange, along with increasing of the thickness of an ice layer, the heat transfer resistance is increased, and consequently, the system energy efficiency is low, and the icing rate is small are overcome. The ice-storage air conditioner comprises an ice-storage barrel and a heat exchanger; the heat exchanger is placed in the ice-storage barrel, and comprises a shell and a refrigerant runner arranged in the shell; the shell comprises a heat exchange face and a non-heat-exchange face; the face opposite to the bottom of the ice-storage barrel is the non-heat-exchange face; when refrigerants subject to throttling down and decompression flow through the refrigerant runner forwards, water in contact with the heat exchange face is cooled and iced; when the refrigerants flow through the refrigerant runner in a reverse manner, ice in contact with the heat exchange face is partly molten, and the ice is separated from the heat exchange face upwards under the buoyancy effect.

Description

technical field [0001] The invention relates to the field of ice storage, in particular to an ice storage air conditioner and an ice storage method. Background technique [0002] In large domestic cities, the distribution of power demand is extremely unbalanced within 24 hours a day. The peak of power consumption is generally concentrated from 8:00 am to 6:00 pm, while the low point of power consumption is concentrated from 9:00 pm to 6:00 the next day. According to this , The country has formulated a peak-valley electricity price policy, and the peak-valley electricity price difference has reached more than 4 times. Therefore, it has become a research hotspot to use the low-load low-load electricity of the power grid at night to make ice, and use the ice produced as a cold source to provide cooling to places that need cooling during the day when electricity is in short supply. . [0003] At present, in cities with large electricity consumption, air-conditioning accounts f...
