Abstract

PURPOSE:To facilitate the temperature control of a snow layer and save the energy more efficiently by heat-exchanging between an air layer below the snow layer and an open air so as to heat the air in the air layer and increasing the temperature of the lower part of the snow layer so as to melt the snow in the lower part of the snow layer. CONSTITUTION:When melting the snow the lower part of a snow layer 3 by heating an air layer 4, a first valve 9 and a second valve 14 are switched over so that an open air may be absorbed by an air layer heater exchanger 10. On the other hand, a third fan 13 is used to heat-exchange the air circulating in the air layer 4 with the open air by way of the heat exchanger 10. The holding heat of the air in the air layer 4 heated up with the open air is transmitted to the lower part of the snow layer 3 by way of a floor 2, thereby melting the snow. The open air, which is heat- exchanged and cooled, is fed to a building supply and exhaust air service heat exchanger 7 with a second fan 11 where the open air is heat-exchange with a part of exhaust cooled air from the building 1 and further cooled. This open air is fed to an air conditioner 5 together with the open air directly absorbed into the heat exchanger 7 where the temperature is adjusted and fed into the building 1 while a setting temperature is maintained.
