We must develop many techniques for the usage of a natural energy from the viewpoint of energy saving and keeping environment clean. In this study, we developed a simple system that could control both temperature and humidity of a general office, when we could use snow stored until summer as a cold heat source of an air-conditioner. In this report, we adopted a most simple analytical model of all air, central control and variable air volume type air-conditioner which had a blower and a single duct in order to investigate the basic characteristics, and we examined temperature and humidity analytically. As a result, the temperature of the air conditioner area could be achieved 17°C of air at the entrance and 27°C at the exit which temperatures were purposed in this analysis. However, the mean humidity of 60% could not be achieved under lower fresh air humidity than 55%, and the mean humidity became the near to the humidity of fresh air. Because this snow air-conditioning system has excellent controllable characteristics and succeeds a filter effect at the snow surface, we can hold expectation to spread this system in a snowy district widely.
