A removal method of snow accumulated on a photovoltaic (PV) array installed at a pantiled roof was examined using a model house in 1994/1995 winter season. The photovoltaic array with a rate of 1kW consists of ten PV panels and each panel was individually heated by injecting do current from a dc power supply. The roof surface around the array was covered with the electrically-heated roof tiles. When snow slides down from the panels and the temperature at the under surface of the panel rises to 3 degrees, the heating circuit automatically turns off and the system for generating electric power turns on. Snow on the photovoltaic array and the pantiled roof usually slides down within 3 to 4 hours after heating. The snow sliding system works effectively in assistance of sunshine. After snow sliding, the photovoltaic array can generate electricity in a sunny day, although the gained energy is less than whole energy to snow removal. Since the generated power is considerably reduced owing to the existence of a little snow lump on the array, snow should be removed clearly.

Diffusion of studlesstires have almost completed in cold region in the winter of 1992. In proportion as studlesstires are come into wide use, road surface become slippery. And characteristics of winter traffic accidents are changing, as shown in the increase of slip accidents. For prevention of winter traffic accidents, of course, thoroughgoing countermeasures to road surface management are firstly neened. Furthermore it is necessary to improve road alignment to meet the changes of those characteristics. Also revising drivers' safety consciousness is needed to make up for countermeasures to road surfacemanagement in the circumstance when those countermeasures are still insufficient. This paper discusses countermeasures to road surface managements and road alignment and problems of drivers' sefety conciousness from analyses of characteristics of winter traffic accidents.

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.
