Study on natural cool energy storage and utilization technology

There is hot summer and long winter with cold weather in north China. In summer, the control of the environment in rooms and livestock, poultry´s houses as well as the storage and preservation of fresh agricultural products and by-products needs to consume large amounts of energy especially the non-renewable sources of energy. The full use of these climatic characteristics in these areas to store the natural cold energy from winter to summer will achieve the saving of the energy and improve environment condition. Based on the analysis of the domestic and international experience with the usage of natural ice and snow storage and cool energy exchanging technology, the idea of using the winter natural outdoor frozen ice as the source of cold which will be stored to summer has been put forward, through indirect heat exchange of technologies for environmental temperature control line, combined with the climate characters in the North and test conditions, has been systematically studied.
