PROBLEM TO BE SOLVED: To provide a snow surface temperature control device for an indoor snow layer installation wherein temperature of a snow surface is adjusted to keep a snow surface at a slide adaptation state from the viewpoint of a temperature/humidity by predicting a change in temperature and humidity of air in the indoor snow layer installation, and taking variations of the number of sliding persons into consideration, and estimating a dew point of air on the snow surface. SOLUTION: A snow surface temperature control device 7 for an indoor snow layer installation is adapted such that a heat exchanger 6 is provided on a slanting floor 2 for cooling a snow layer formed on the slanting floor 2, and further control means is provided for adjusting the degree of cooling of the heat exchanger 6 such that temperature of the snow surface is brought into coincidence with the dew point of air B on the snow surface. In the device, the snow layer is cooled with the heat exchanger 6 whereby water condensation and frosting onto the snow surface from the air B on the snow surface are prevented from happening and water sublimation from the snow surface to the air B on the snow surface is prevented from happening. |
