Successfully adjusts the supercooling refrigeration system with the maximal supercooling degree up to 33.5 ℃ when condensation temperature is 41.5 ℃. The refrigeration capacity of new system increases 20.4% than conventional air conditioning systems. Analyses the relation of supercooling degree to cooling capacity of chilled water and refrigeration capacity increment. Discusses the dynamic property of refrigeration system and cooling storage system in supercooling refri...
