Evaluation of the heat exchange characteristics and strength of stored snow in the snow cooling system with water circulating

通过实验研究了在贮雪槽中贮存4个月左右的雪与流过贮雪槽底部的水之间的热交换特性。20英尺。冷藏集装箱被改装成雪库。结果，获得了以下知识。雪颗粒相互联合收割机形成整个储存雪的块。贮存期越长，粘结强度越大。因此，即使在雪的融化进行时，储存的雪也几乎不会福尔斯掉落到水中。雪的这些特性导致冷却水的效率降低。如果在储存的雪中出现裂纹并且雪块分离，则冷却水的效率暂时提高。随着雪库水位的升高，冷冻水的效率变高，但在10 cm左右达到饱和。

A characteristics of the heat exchange between the snow reserved in the snow storage for about 4 months and water flowing through the bottom of the stored snow was investigated experimentally. A 20 ft. reefer container was modified into the snow storage. As the result, the following knowledge was obtained. The snow particles combine with each other to form a block of the whole stored snow. The bonding strength of the stored snow fairly increases for a long stored period. Thus, the stored snow hardly falls off into the water even when melting of the snow proceeds. These characteristics of the snow cause reduced efficiency of chilling water. If the crack occurs in the stored snow and the snow block separates, the efficiency of chilling water improves temporarily. The efficiency of chilling water becomes higher as the water level in the snow storage rises, but saturates at about 10 cm levels.
