2006年4月に33tの雪室をビルトインした住宅が新潟県小千谷市に建築され,2006から2008年にかけて,雪室の貯雪性能,雪冷房システムの冷房性能,空気清浄効果についての実証試験が行われた.雪室に入れて貯蔵された雪は,3室26畳の空間をひと夏通じて冷房しても9月中旬頃まで残った.冷房室は設定された25〜27℃に維持され,市販のエアコンに比べてそん色ない性能を発揮した.湿度は,雪表面における除湿効果で連続運転によって50%以下にまで下がった.粉塵量・臭いレベルの測定から,空気清浄効果が確認でき,特に高い除塵効果が示された.雪冷房運転のための電力消費は,3室合計で年間1500円以下であり,成績係数は平均11程度となり,エネルギー効率の高い冷房であることが示された.

The Chinese crude drugs "Huajiao (花椒)" and "Jiaomu (椒目)," and the Japanese crude drug "Sansho (山椒)" are derived from mature fruit of genus Zanthoxylum plants of the Rutaceae family. "Huajiao" and "Sansho," are prepared from the pericarp, and used as an aromatic stomachic and "Jiaomu," is from the seed, and used as a diuretic. A market survey of these crude drugs in China and Japan, showed that there are samples of apparently different external morphologies, suggesting that there are samples of different botanical origins. To clarify the original plants of such crude drugs, a pharmacognostical study was made. This paper deals with the origins of "Sansho" in the Japanese market. Comparative anatomical studies were performed mainly on the pericarps and seeds of Z. piperitum, two kinds of Z. piperitum f. inerme (Asakura-zansho and Budo-zansho), Z. armatum var. subtrifoliatum, Fagara mantchurica, F. ailanthoides by optical and scanning electron microscopy, which showed that they could be distinguished from each other by the following characteristics: in the pericarp, the length of equatorial circumference, thickness of pericarps and endocarps, diameters of oil sacs, micro figure of cuticle and the number of epidermal cells over oil sacs on surface view; in the seed, the diameters of epidermal cells on surface view, the rate of inner sclereid layers in the outer seed coat, etc. The commercial samples examined were identified as a mixture of slightly immature pericarps of Budo-zansho and Asakura-zansho in a ratio of 9 : 1 or 6 : 4, a mixture of slightly immature pericarps of Z. piperitum, Budo-zansho and Asakura-zansho in a ratio of 8 : 1 : 1, or mature pericarps of Z. piperitum only.

Recently, a large number of air-conditioning system that uses the snow as cold energy source (snow cooling system) has been increasing due to the environmental emerging that is represented by the global warming. While the reducing of the operational cost of this system is advanced, there is a demand for a simple cooling system that can be used in the necessary places where the snow mound is available to supply the cold energy source. Therefore, we have been starting the research and development of a movable package type of snow air-conditioning system since 2001.<br>Based on how to gain the cold energy from snow, the snow cooling system can be divided into two types: Air circulation type and Cold-water circulation type. In this paper, we report an experimental research and development of a cold-water circulation shower type of the snow cooling system.
