This is a health care system for the elderly that employs both a full pneumatic subsystem and a cold water circulation subsystem, for the first time in Japan. The use of the two subsystems in combination has optimized the space cooling in a home occupied by both care givers and care receivers. Local governments and enterprises concerned are highly interested in the system, and this case contributes to promoting the widespread use of similar systems. This has been evaluated as a model for snow-based space cooling in the future.

Features of Equipment, System and Facilities

In this northern district, it is planned to use the burdensome snow usually accumulating up to meters, as energy for space heating in summer. According to the plan, storage for storing the snow is formed in a building, to store the snow till summer, and in summer of the space-cooling season, the heat of the snow is used to cool the spaces of respective rooms. Unlike the conventional space cooling means of using electric air conditioners, there is neither the waste heat from the outdoors installed machines nor the use of chlorofluorocarbons promoting the global warming.
