To improve construction characteristics and workability, by reducing the thickness of heat insulating material and compacting a radiation air conditioner.
In the radiation air conditioner, by using a vacuum heat insulating material using glass fiber with a thickness of three microns as a core material of heat insulating material in an uppermost part of a duct composition of a radiation panel rear face, bulkiness is eliminated, and the construction characteristics and workability are improved. By laminating fiber of the glass fiber, arranging fiber directions in the same direction, and using a high performance vacuum heat insulating material with a coefficient of thermal conductivity of 0.0025 W/mK or less, an energy saving effect is improved.
