Description
Technical field
The present invention relates to the device that a kind of dynamic system is starched for ice, starch for the preparation of ice.
Background technology
For a long time, ice all has a wide range of applications in air-conditioning, fresh-keeping and industry processes, especially it is worth mentioning that, along with China's economy and social fast development, cause power supply shortage, network load energy imbalance becomes increasingly conspicuous, and day electricity consumption peak-valley difference and year electricity consumption peak-valley difference increase.Ice conserve cold becomes a kind of important solution, has important energy-saving significance.Although China makes some progress in the development and application of ice Thermal Storage Air-Conditioning Technology, but still is in the starting stage, far can not compared with the developed country such as the U.S., Japan, in China, research and extension ice Thermal Storage Air-Conditioning Technology prospect is boundless.
One of key technology of ice conserve cold is ice-making technology.The ice-making technology of ice-storage system has two large classes both at home and abroad at present: static ice making and dynamic ice-making.What current domestic and international application was more is melt ice on coil and encapsulation Ice system, but for ice hockey ice-reserving, in, outer coil pipe ice-reserving method, common feature is exactly that the forming process of ice belongs to a static category, after ice is formed on solid coolant face, thermal conductivity factor due to ice is far smaller than the thermal conductivity factor of metal, thermal conductivity factor as copper when 0 DEG C and aluminium is respectively 401 and 236, and ice is only 2, the existence of ice sheet causes very large heat transfer resistance, and sharply increase with the increase of ice layer thickness, thus cause the system heat transfer temperature difference large, ice making energy consumption is high, ice making speed also with ice sheet thicken and slack-off.As can be seen here, if solid heat transfer face can be avoided in ice-making process to freeze, the thermodynamic efficiency of ice-making system can greatly be improved.
In the last few years, fluidic ice (be also called ice slurry, Ice Slurry) generation be applied in ice making circle and cause extensive emphasis.Fluidic ice is the mixture be made up of tiny ice particle and water, owing to producing without ice sheet on solid heat transfer face in fluidic ice producing process, realize complete fluid interchange, it is dynamic ice-making category, therefore dynamic ice-making process heat transfer temperature difference is little, and the comparable ice cube of producing of thermal performance coefficient producing fluidic ice improves nearly one times.And because produced fluidic ice has, storage density of cold is large, heat transfer property good, the remarkable advantage such as flowable and aid pumpability.
Dynamic ice-making technology has unrivaled advantage compared with traditional static ice-making technology, and the research and development based on the ice-chilling air conditioning system of dynamic ice-making technology become hot issue.But because the equipment cost producing fluidic ice technology is high, the problem such as the low and technical risk of system reliability is large, although existing a small amount of engineer applied, the application development of this ice Thermal Storage Air-Conditioning Technology is still very restricted at present, and is mainly in the experimental study stage.
