11 is provided in the partition plate 1 so as to face upward. On the other hand, both the inlet 12 and the outlet 13 of the second cross-flow fan 9 are opened in the front panel 3 with their positions vertically shifted so that the inlet 12 is on the upper side and the outlet 13 is on the lower side.
A heat exchange air outlet 14 is opened at the upper end of the partition plate 1, and the air from the air outlet 11 of the first crossflow fan 8 passes between the heat exchange fins 7 of the radiant cooling / heating plate 5 and blows out from here. It is supposed to be done. 15 is a partition board 1
This controller is installed at the bottom of the

が第８図のごとく不均一となる。(Problems to be solved by the invention) Therefore, if the same size of heat exchange fins (dimensions L × H × B in FIG. 6) are installed in all of the plurality of thermoelectric elements, the thermoelectric element radiating side aligned with the flow direction of the blast will be considered. The temperature distribution of the panel 5 becomes non-uniform as shown in FIG.

差が生じ，身長の違いや人間の座る場所により温度が異
なるという欠点がある。This is because the air blows away heat from the heat exchange fins on the blower fan side (air inlet side), and the heat is exchanged with the heat exchange fins next by warm airflow, so the performance deteriorates as it moves toward the air outlet side, and This is because the temperature will not drop. Due to this uneven temperature, the radiation effect varies depending on the position in front of the panel, and the temperature varies depending on the height and the place where a person sits.

構成としている。(Means and Actions for Solving the Problem) Therefore, according to the present invention, a radiation absorbing / dissipating portion is provided, in which a plurality of thermoelectric elements are attached to the back side of the panel and heat exchange fins for exchanging heat of the thermoelectric elements are provided. In the radiant cooling and heating machine that attaches the panel to the front side of the partition plate and positions the heat exchange fins inside the partition plate, and blows the heat exchange fins with a fan to cause the panel to absorb and release heat,
In order to make the temperature distribution of the panel almost uniform, the heat transfer area of the radiating fins is gradually increased in accordance with the direction of the air flow of the fan flowing through the heat exchange fins provided for each thermoelectric element.
このため熱交換フィンの幅，高さ，又は枚数をファン側
（空気入口側）よりも放熱出口側で広くしている。For this reason, the width, height, or number of heat exchange fins is made wider on the heat radiation outlet side than on the fan side (air inlet side).
従って熱交換フィンを流れる送風が漸次温まっても伝熱
面積を大きくしているためほぼ均一の熱交換を行なうこ
とが出来るので，パネルの温度分布をほぼ均一にでき
る。Therefore, even if the airflow flowing through the heat exchange fins gradually heats up, the heat transfer area is increased, so that almost uniform heat exchange can be performed, and the temperature distribution of the panel can be made substantially uniform.
