PURPOSE: An air-conditioning apparatus using heat exchange between liquid oxygen and gaseous nitrogen is provided to perform cooling in the summer season and heating in the winter season by inducing convection through copper to an indoor place. CONSTITUTION: An air-conditioning apparatus using heat exchange between liquid oxygen and gaseous nitrogen comprises wallpaper(3) made of copper fiber for securing heat conduction. When oxygen and nitrogen become gaseous, an extra space is made in tanks(1,2) which are attached to a corner of a ceiling. Therefore, convection is made without an additional energy source. |
