Use prospect.
Since building whole year load variations are very big, design conditions run time is generally below 10%, i.e., refrigeration unit is most
When refrigerating capacity is consistent with design conditions air conditioner load greatly, refrigeration unit still had 90% time to be in sub-load operating.Therefore, it makes
The cold group most of the time is in underrun, and refrigerating efficiency is relatively low, and corresponding energy waste is very big, therefore using high-temperature phase-change
Cool Storage Technology stores the extra cold met other than building cooling；The cold of storage is released when needed to build
Object cooling is built, it is accordingly that refrigeration unit is out of service；So repeatedly, it is designed by reasonably storing/letting cool scheme and operation reserve,
It carries out storing/letting cool adjusting especially in accordance with time-of-use tariffs, refrigeration machine can not only be made to maintain energy-efficient operation under design conditions,
Efficiency of refrigerator is improved, reduces energy consumption and environmental pollution；Electric power " peak load shifting " is additionally aided, substantially saves the electricity charge, is adjusted
Save network load.
The present invention is directed to existing air conditioner load dynamic change, refrigerator system underload and the present situation of fallback, with
The energy-efficient operation of refrigeration machine and electric power peak load shifting are target, by organic phase-change cool storage material heat transfer enhancement technology and machine
Reason, High Temperature Phase Change Cool Regeneration Plant structure design, that phase transition process stores/let cool dynamic characteristic, High Temperature Phase Change Cool Regeneration Plant is stable
Property is studied, and develops a kind of High Temperature Phase Change Cool Regeneration Plant.
