PURPOSE:To utilize night electric power effectively without providing independent heat accumulating tank by a method wherein latent heat accumulating bodies, formed into specified configuration, are arranged along the flow of air and the air is discharged into a cooling or heating chamber provided at the outside of the duct while effecting heat exchange between latent heat accumulating body. CONSTITUTION:In the duct device for sending airflow, whose heat is exchanged by a heat source or a cold heat source, the latent heat accumulating bodies (mixed freezing medium of phosphoric acid, urea, caustic potash or the like, for example,) 22, formed into specified configuration, are arranged along the flow of said air and the air is discharged into a cooling or heating chamber 1, provided at the outside of the duct, while effecting heat exchange between the latent heat accumulating bodies 22. Accordingly to this method, the energy saving heat and cold heat accumulation, utilizing surplus space such as a space in the duct or the like may be effected without providing any independent heat accumulating tank and, as a result, late night electric power may be utilized effectively. |
