Since the through holes 18 allow the air in the front and back spaces of the slab 10 to flow, it is usually highly efficient to have two or more. In the drawing, the indoor unit of the air-heat type heat pump 22 is provided at each of the left and right ends, and the through hole 18 on the left side is provided on the rear surface side of the slab 10, that is, on the rear ceiling side from the rear surface of the slab 10. The right through hole 18a is opened as it is through the duct 24 for the guide passage. Then, the blower 2 which is integrally attached to the ceiling panel 16 at an arbitrary position and can control the rotation speed
6 is provided.

Therefore, at the start of air conditioning, the slab has already reached a cold (warm) heat state that is equal to or higher than the set room temperature, so the "rise" is quick. That is, the precooling heat time becomes short.

Also, by using a ceiling panel with good heat radiation characteristics, heat radiation from the ceiling surface can be obtained, so a mild head cold foot heat effect is obtained during cooling, and cool air does not directly blow to the body and is comfortable. A comfortable air-conditioned space is obtained, and the heat radiation effect keeps the entire room close to an appropriate temperature during the night.

Further, since the cold / hot air is forcedly circulated from the cold / hot air passage by the blower, a uniform temperature distribution can be quickly obtained without heat retention, and it is possible to quickly respond to changes in the indoor temperature. Moreover, since the heat is stored in the slab, even if the heat capacity of the heat exchanger is reduced, the insufficient heat is replenished from the slab, and the surplus power at night can be effectively utilized.
