PURPOSE:To relieve the peak of electric power demand, and contrive energy saving as well as the reduction of cost for cooling by a method wherein snow is received into a given vessel to store it in a snow storing chamber, the snow is introduced into a heat accumulating chamber as it is in summer to melt it in a heat accumulating tank and/or in a circumferencial instruments thereof in accordance with the demand of cooling and cold storage. CONSTITUTION:In the season of snow fall, snow is dropped into a recovering port 2 to introduce it into a preparation chamber 10, then, is received into the vessels 40 of given specification by dividing it and stores it in a snow storage chamber 30, having a depth more than a given value under the ground and a thick wall. In summer, the snow, received in the vessels 40, is transported from the snow storage chamber 30 into the heat accumulating tank 60 through a transfer passage 50 by opening a door 21 to float the snow 61 on water in the heat accumulating tank 60. In order to obtain cold heat from snow blocks 61 floating in the heat accumulating tank 60, a fan 102 is employed to suck outside air, having a high temperature, through an air inlet port 100 installed in a town district. According to this method, airflow, produced by the fan 102, reduces the temperature thereof by melting the snow in the heat accumulating tank 60. Thereafter, the airflow, whose temperature is reduced, is pulled out by another fan 103 and is discharged out of an air outlet port 104. |
