In the cold climate and deep snow regions in the winter season of Japan, it has been advanced to utilize the snow as the cold energy source for air conditioning in summer. In this study, a system to extract the chilled air directly from the snow mound of several thousand ton through a horizontal borehole in it is proposed. Some troubles caused by mud in the snow melting water can be avoided by means of transferring heat from the melting water to the supply air. The thermal design for the heat exchange of this system is carried out by theoretical means and verified by the practical experiment. According to results of the experiment, it is proved sufficiently that the theoretical thermal design method predicts appropriate values of the system. The snow cooling system has been applied to a strawberry seedling greenhouse with 270m<sup>2</sup> as a practical experiment. And predicted values and experimental results are 9.90 kW as the cooling power gained from the snow mound using two blowers needed 0.8 kW totally.
