Therefore, the radiation panel area can be changed. Therefore, energy loss can be eliminated as compared with the conventional case of heating and cooling a constant radiation panel area. Also, since the most comfortable panel temperature suitable for the room temperature is set based on the signal from the temperature sensor to control the temperature of the hot and cold water, the panel temperature can be set independently of the conventional room temperature. The radiation environment will be more comfortable than when it is done.

Set Tp. FIG. 2 shows the optimum panel temperature Q 1 at any one of the indoor temperatures T 1 , T 2 and T 3 in relation to comfort. When the comfortable panel temperature Tp is set, the process proceeds to step n5,
It is determined whether or not the current operation of the radiant panel 1 is cooling, and when it is not cooling, the process proceeds to step n10, and the temperature of the hot / cold water is controlled so that the set comfortable panel temperature Tp is obtained. When it is determined in step n5 that the air conditioner is cooling, the process proceeds to step n6 and it is determined whether the comfortable panel temperature Tp is equal to or lower than the dew condensation temperature Tc. And
When the comfortable panel temperature Tp is higher than the dew condensation temperature Tc, the process proceeds to step n10, and the same cold / hot water temperature control is performed.
That is, when the comfortable panel temperature Tp is higher than the dew condensation temperature Tc, the temperature of the cold / hot water is controlled by the comfortable panel temperature Tp, and compared with the conventional example in which the panel temperature is set independently of the room temperature. Therefore, comfortable radiant cooling and heating can be performed.

適な輻射環境が得られるという効果がある。As described above, according to the present invention, the cold / hot water from the cold / hot water supply means is individually supplied to the plurality of radiation panels via the plurality of valves. Then, the control device selects the radiation panel to be operated based on the signal from the human body position detection sensor that detects the position of the occupant arranged on the surface of the radiation panel, and selects only the valve corresponding to the radiation panel. Since it is configured to control the temperature of the hot and cold water by opening the panel and setting the most comfortable panel temperature suitable for the room temperature based on the signal from the temperature sensor, the radiation panel area must be variable and must be close to the person in the room.
