HEAT STORAGE TYPE HEATING APPARATUS USING HOT AIR

摘要

According to the present invention, an heat storage type heating apparatus using hot air comprises: an air supply duct inserted into the structure to supply air thereinto; an air discharge duct extended from the structure to discharge air therefrom; a working fluid supply unit which supplies working fluid to the air supply duct or the air discharge duct to provide heat energy to the air flowing along the ducts; a heat exchange unit which performs heat exchange between the air flown from the air supply duct to the air discharge duct and the working fluid supplied from the working fluid supply unit; and a heat transfer unit which absorbs heat energy from the air discharged from the structure to the outside and transfers heat to the air flown along the air supply duct into the structure.
