项目摘要
The inner ground has been frozen perfectly and turned permafrost in low temperature storage facility from the ten years data. The surface of ground was thawed from summer to early winter, and again was frozen showing the same pattern every year. The numbers of 216 heat pipes were found to be too great effective for cooling system, so it concluded that the numbers of heat pipes would be about fifty for this storage system. The weight loss of stored vegetables was under 5 percent and this system was found suitable for long term storage of root vegetables. The storage ability could not be confirmed for apples because of errors from few samples in this case.According to investigation of ground bank vegetation around the storage, Japanese larch (Larix leptolepis) took priority by wind scattering from wind break forest. In the frozen field experiments for water absorbent polymer, the thermal resistance was found in the surface of thawing condition. It was suggested that the structure of central latent heat bodies could be benefit for cost down using freezing pure water. It found that the resistivity of boundary between frozen and unfrozen ground was not clear, but the relationship between resistivity and temperature was obtained and two dimensional distribution of frozen front was shown. As the results, the balance of volumetric frozen mass could be estimated throughout years.
从10年来的资料来看,低温冷库内地面已完全冻结,并已成为多年冻土。从夏季到初冬,地面解冻,每年再次冻结,显示出相同的模式。发现216根热管的数量对于冷却系统来说太大了,因此得出结论,对于该存储系统,热管的数量大约为50根。贮藏过程中蔬菜的失重率小于5%,适宜于根菜类蔬菜的长期贮藏。在这种情况下,由于样本数量少的误差,无法确定苹果的储存能力。根据对储存库周围的地面植被的调查,日本落叶松(落叶松)被防风林的风散射优先。在保水剂的冻融试验中,发现保水剂在冻融条件下表面存在热阻。指出采用中心潜热体结构有利于降低冷冻纯水的成本。结果表明,冻土与未冻土边界电阻率不明显,但得到了电阻率与温度的关系,并给出了冻土锋面的二维分布。结果表明,可以估计多年来体积冻结质量的平衡。
