It is very important to introduce natural energy for keeping environment clean and saving fossil energy. In the many kinds of natural energies, snow is excellent to be stored for long-term and has an advantage to be utilized with simple system. The air-conditioning using snow is called as snow air-conditioning. One of the direct heat exchanging system between snow and air has been developed and widely used. In this system, hot air is cooled through the vertical holes drilled in the snow pile. In spite of many advantages of this system, there are some defects, for example, many small holes have to be drilled at the beginning of use this system. To improve those defects, in this paper, the authors propose a new type heat exchanging system, that is the cross flow type one. In this system, hot air is cooled on the snow surface. In this paper, the authors investigated the characteristics of heat transfer between snow surface and air experimentally.
