Abstract
From the viewpoints of global warming and depletion of ozone layer, natural working fluids are used in heat pumping technology. Water/ice system is selected as natural working fluid for cold heat storage and transportation. There are two big problems in use of water/ice system in cold heat storage and transportation system. They are supercooling phenomenon in ice crystal nucleating and agglomeration phenomenon of ice slurry in storage tank or pipe line. In this paper, the suppressing method of these phenomena by use of some additives, etc. is introduced.
