このように放射ユニットは快適空間をつくる一助となっているが、構造が複雑でコスト高となる問題があった。 Thus, the radiation unit helps to create a comfortable space, but there is a problem that the structure is complicated and the cost is high.

本発明は上記課題を解決するため、長方形の扁平形状であってその長辺方向に空調用空気が流れる第１チャンバ部と、長方形の扁平形状であって前記扁平の方向に前記第１チャンバ部を重ねるように隣り合わせて設けた第２チャンバ部と、を備え、前記第１チャンバ部が、前記第２チャンバ部に接して前記第２チャンバ部に前記空調用空気を出す第１通気部を、備え、前記第２チャンバ部が、前記被空調空間に接して前記被空調空間に前記空調用空気を出す第２通気部と、蓄熱部と、を備え、前記第１通気部が、前記第１チャンバ部から前記第２チャンバ部に前記空調用空気を出す第１貫孔を、所定開口率となるように多数備え、前記第２通気部が、前記第２チャンバ部から前記被空調空間に前記空調用空気を出す第２貫孔を、所定開口率となるように多数備え、前記第１通気部の開口率を４０〜６０％に設定し、かつ前記第２通気部の開口率を７０〜８０％に設定し、前記蓄熱部が、前記第１通気部の前記第１貫孔を通った前記空調用空気の流れる方向に沿って隙間があくように互いに間を隔てて配置されると共に前記隙間に前記空調用空気を分流拡散させながら整流状に通過させて前記第２通気部の前記第２貫孔から前記被空調空間へ出させかつ前記空調用空気の熱を蓄めて前記第２通気部に熱伝達させて前記第２貫孔と前記第２通気部から前記被空調空間へ放射させるプレートを、備えたことを最も主要な特徴とする。 In order to solve the above-mentioned problems, the present invention has a rectangular flat shape and a first chamber portion through which air for air-conditioning flows in the long side direction thereof, and a rectangular flat shape and the first chamber portion in the flat direction. A second chamber portion provided adjacent to each other so as to overlap , wherein the first chamber portion is in contact with the second chamber portion and emits the air-conditioning air to the second chamber portion, The second chamber part includes a second ventilation part that contacts the air-conditioned space and emits the air-conditioned air to the air-conditioned space, and a heat storage part, and the first ventilation part comprises the first A plurality of first through holes for letting out the air-conditioning air from the chamber part to the second chamber part have a predetermined opening ratio, and the second ventilation part is provided in the air-conditioned space from the second chamber part. The second through-hole for discharging air for air conditioning has a predetermined opening ratio. The opening ratio of the first ventilation part is set to 40 to 60%, the opening ratio of the second ventilation part is set to 70 to 80%, and the heat storage part is provided to the first ventilation part. The air-conditioning air passes through the first through-hole of the air-conditioning unit while being spaced apart from each other so that there is a gap along the flow direction of the air-conditioning air, and while the air-conditioning air is divided and diffused in the gap. The second through-hole of the second ventilation part is caused to exit from the second through-hole to the air-conditioned space, and the heat of the air-conditioning air is stored and transferred to the second ventilation part to transmit the second through-hole and the second through-hole. 2 The main feature is that a plate for radiating from the ventilation section to the air-conditioned space is provided .

請求項１の発明によれば、第１通気部の開口率を４０〜６０％に設定し、かつ第２通気部の開口率を７０〜８０％に設定して、第１通気部の開口率よりも第２通気部の開口率を大きくすることで、２段階で動圧を弱めて静圧を高めながら徐々に風速を落として、第１チャンバ部と第２チャンバ部の空間全体に空調用空気を行き渡らせることができる。そのため、被空調空間への空調用空気の放出と放射を均等化でき、ドラフト感や温度ムラのない快適空調を行える。２つのチャンバ部に所定の開口率で貫孔を形成する簡単な構造なのでコストダウンでき、剛性を高めながら軽量化を図れて施工やメンテナンスが容易となる。蓄熱部を、空調用空気の蓄熱と整流に兼用でき、熱放射能力が向上し風量ムラと温度ムラを確実に減らせる。全体が扁平形状なので懐の狭い天井にも容易に設置でき、施工やメンテナンスが一層容易となる。
請求項２の発明によれば、第２通気部が波板形状なので放射面積が拡大し、放射能力の向上を一層図れる。 According to the first aspect of the present invention, the opening ratio of the first ventilation section is set to 40 to 60%, and the opening ratio of the second ventilation section is set to 70 to 80%. By increasing the opening ratio of the second ventilation part rather than reducing the dynamic pressure in two steps and gradually increasing the static pressure, the wind speed is gradually reduced, and the entire space between the first chamber part and the second chamber part is used for air conditioning. Can spread the air. Therefore, it is possible to equalize the discharge and radiation of air-conditioning air to the air-conditioned space, and to perform comfortable air-conditioning without a draft feeling and temperature unevenness . Since the two chamber sections simple structure to form a transmural hole at a predetermined aperture ratio can cost, construction and maintenance Hakare weight reduction can be facilitated while enhancing the rigidity. The thermal storage unit, can be also used as heat storage and rectification of the air-conditioning air, heat radiation force be reduced to ensure improved airflow unevenness and temperature unevenness. Because the total body of flat shape can also be easily installed in narrow bosom ceilings, construction and maintenance becomes easier.
According to invention of Claim 2, since a 2nd ventilation part is a corrugated sheet shape, a radiation area can be expanded and a radiation capability can be improved further.
