Energy, food, the environment are basics of the life. The snow can contribute to these many problems to have greatly even if not decisive. The snow/ice as the cold heat source has a remarkable substitute effect for fossil energy as energy. And there is not the discharge of the warm temperature from a system depending for a mechanical refrigerating cycle, and there is an effect for environmental safeguard without using refrigerants such as Freon with this snow air conditioner. In this study, the authors have suggested many systems of the air-conditioner in which the snow is used for cold heat source, and the authors call them all-air type snow air-conditioner and have been analyzing the performance of them. This snow air-conditioner is made by simple construction of a snow storage room, a blower and a dumper for regulation of air flow. The temperature/humidity of the conditioning area is controlled by the mixing hot return air and chilled air from the snow storage room. In this report, the authors discussed on the simplest system among many all air type snow air-conditioning ones. In this system, only the temperature in the air-conditioning area is controlled and this temperature is adjusted by mixing with the circulation hot air through a dumper and the cold air cooled by the snow, and the authors call this system all-air type temperature control β system. In this paper, the system is classified into different three models for the analysis, and characteristics of them are investigated analytically and discussed.
