Being measuring method of the air temperature in the atmosphere above the snowfall device null ice saturation which becomes making use of the measuring method and

摘要

PROBLEM TO BE SOLVED: To provide a snowing device capable of more accurately measuring an air temperature of the atmosphere higher than ice saturation in a snow making room even in a case when the snow making amount and the shape of crystal of snow are changed in the same snowing device by measuring the air temperature of the atmosphere higher than ice saturation in the snow making room.;SOLUTION: In this snowing device where the air cooled to a prescribed temperature and adjusted to the atmosphere higher than ice saturation is circulated through a ventilation member 15 disposed in the snow making room 2, and snow is made by making frost attached to the ventilation member larger, a duct 9 for measuring the air temperature, provided with taking-out means 8, 9, 11 for taking out the specific amount of air at least from the atmosphere higher than ice saturation, a heating means 10 for heating the taken-out air with a specific heat amount to achieve the atmosphere lower than the ice saturation, and a measuring means 12 for measuring the temperature of the heated air, is connected with a circulation system passage through which the atmosphere higher than ice saturation passes, or the snow making room 2 to which the atmosphere higher than ice saturation is distributed.;COPYRIGHT: (C)2009,JPO&INPIT
