Abstract
Description
本発明は、天井面からの熱の放射により室内空間の冷暖房を行うと共に、室内空間へ噴き出す空調空気を併用する放射冷暖房システムに関するものである。 The present invention relates to a radiant cooling and heating system that performs cooling and heating of an indoor space by radiation of heat from a ceiling surface and also uses conditioned air that is blown into the indoor space.
室内空間の温湿度環境を快適にするための空調機は、空調空気を室内空間へ噴き出すものが一般的である。このような空気噴流式の空調機によれば、室内空間に気流が発生し、その気流が人体に直接当たることで不快を感じることがある。また、空気の温度と密度との関係により、冷気は下へ暖気は上へ移動する対流によって上下温度分布が発生し、頭熱足寒の環境となりやすい。そこで、不快な気流感や、室内空間の上下温度分布が発生しにくい放射冷暖房システムが注目され、様々な手法が提案されている。 An air conditioner for making the temperature and humidity environment of the indoor space comfortable is generally one that blows conditioned air into the indoor space. According to such an air jet type air conditioner, an air flow is generated in the indoor space, and the air flow directly hits the human body, which may cause discomfort. Also, due to the relationship between the temperature and density of the air, the convection in which the cool air moves down and the warm air moves up tends to generate an up-and-down temperature distribution, which tends to be an environment of cold head heat. In view of this, a radiant cooling and heating system that is less likely to cause an unpleasant airflow feeling and a vertical temperature distribution in an indoor space has been attracting attention, and various methods have been proposed.
従来、放射冷暖房システムとしては、
(1) 天井スラブなどのコンクリート内部に冷温水配管を埋設し、この配管に冷却水あるいは加熱水を供給して、天井面からの放射により室内空間の冷暖房を行う手法
(2) 天井又は床に通気性のあるパネルを取り付けて、このパネルに配設したむきだしの冷温水配管に冷却水あるいは加熱水を供給することにより室内空間の冷暖房を行う手法
(3) 天井裏空間を密閉空間とし、この天井裏空間に空気調和機からの冷却空気又は加温空気を供給して、天井面からの放射により室内空間の冷暖房を行う手法（下記の特許文献１参照）
が知られている。
Conventionally, as a radiant air conditioning system,
(1) A method of embedding cold / hot water pipes inside concrete such as ceiling slabs, supplying cooling water or heating water to the pipes, and cooling / heating the indoor space by radiation from the ceiling surface
(2) A method of air-conditioning an indoor space by attaching a breathable panel to the ceiling or floor and supplying cooling water or heating water to the bare cold / hot water piping arranged on this panel
(3) A method in which the ceiling space is a sealed space, cooling air or warming air is supplied from the air conditioner to the ceiling space, and the indoor space is cooled and heated by radiation from the ceiling surface (the following patent document) 1)
It has been known.
ところが、上記(1)の従来技術によれば、天井スラブなどのコンクリート内部にいったん埋設した配管は容易に取り出すことができないため、メンテナンスが不可能であり、建物の施工主になかなか受け入れてもらえない。しかも、夏季に重要な湿度制御（除湿）機能がないため、別途、湿度制御機器が必要になる問題があり、さらに、天井スラブなどのコンクリートの熱容量が大きいため、冷暖房の立ち上がりが悪く、快適な空間となるのに長時間を要する問題がある。 However, according to the prior art of (1) above, since pipes once embedded in concrete such as ceiling slabs cannot be easily taken out, maintenance is impossible, and it is difficult for construction contractors to accept. . Moreover, since there is no important humidity control (dehumidification) function in the summer, there is a problem that a separate humidity control device is required. Furthermore, because the heat capacity of concrete such as ceiling slabs is large, the rise and fall of air conditioning is poor and comfortable. There is a problem that it takes a long time to become a space.
また、上記(2)の従来技術によれば、容易に冷温水配管のメンテナンスはできるが、冷房時、冷えた配管に空気が触れることによって結露してしまうため、結露水を処理するドレンパンやドレン配管が必要となり、また、頭寒足熱となる快適空間を提供するためには、冷房用の配管を天井に配設し、暖房用の配管を床に配設する必要があるため、コストが高くなる問題がある。しかも(1)の従来技術と同様、湿度制御機能がないため、別途、湿度制御機器が必要になるものであった。 In addition, according to the prior art of (2) above, the maintenance of the cold / hot water pipe can be easily performed, but during the cooling operation, condensation occurs when the cold pipe is touched with air. Piping is necessary, and in order to provide a comfortable space that can be feverish, it is necessary to install cooling piping on the ceiling and heating piping on the floor, which increases costs. There is. Moreover, as with the prior art of (1), since there is no humidity control function, a separate humidity control device is required.
また、上記(3)の従来技術も湿度制御機能がなく、あるいは除湿能力が一般的な室内対流による空調方式より劣るため、別途、湿度制御機器が必要になる問題があり、しかも天井裏空間がある程度加熱あるいは冷却されないと、天井面から室内空間への放射が行われないため冷暖房の立ち上がりが悪く、室内空間が快適な空間となるのに長時間を要していた。そしてこの技術によれば、夏季には天井面からの冷熱放射によって、室内空間は頭寒足熱の快適環境とすることができるが、暖房期は、冷房期とは逆の頭熱足寒となってしまうので、年間を通して快適な空間を提供することは困難であり、室内空間で発生した水分を透湿性のある天井材を用いて天井裏空間へ透過させることによって除湿効果を期待しているが、一般的な室内対流による空調方式に比較して、除湿能力が大きく劣る懸念があった。 In addition, the prior art (3) has no humidity control function, or has a dehumidifying capacity that is inferior to that of a general air-conditioning system using indoor convection. If it is not heated or cooled to some extent, radiation from the ceiling surface to the indoor space is not performed, so that the start-up of the air conditioning is poor, and it takes a long time for the indoor space to become a comfortable space. And according to this technology, the indoor space can be made into a comfortable environment of head cold foot heat by the cold heat radiation from the ceiling surface in the summer, but the head heat foot cold is opposite to the cooling season in the heating period. Therefore, it is difficult to provide a comfortable space throughout the year, and the dehumidifying effect is expected by allowing moisture generated in the indoor space to permeate into the ceiling space using a moisture-permeable ceiling material. There was a concern that the dehumidifying capacity was greatly inferior compared with the air conditioning system using indoor convection.
また、上記(1)〜(3)の従来技術はいずれも、ある程度の気流感を好む人にとって最適な空調システムとは言えないものであった。 In addition, none of the prior arts (1) to (3) described above can be said to be an optimal air conditioning system for a person who likes a certain level of airflow.
本発明は、以上のような点に鑑みてなされたものであって、その技術的課題は、冷熱又は温熱の放射による室内空間の冷暖房を行うシステムにおいて、天井面からの放射による冷暖房の立ち上がりの悪さを改善すると共に、除湿能力の向上及び室内空間の気流感の向上を図ることにある。 The present invention has been made in view of the above points, and its technical problem is that in a system for cooling and heating an indoor space by radiation of cold or warm heat, the rise of cooling and heating by radiation from the ceiling surface is performed. In addition to improving the badness, it is intended to improve the dehumidifying ability and improve the feeling of airflow in the indoor space.
上述した技術的課題を有効に解決するための手段として、請求項１の発明に係る放射冷暖房システムは、天井材の裏側に画成された天井裏空間と、壁材の裏側に画成され前記天井裏空間に連通する壁裏空間と、天井裏空間及び室内空間の空気を取り込んで前記天井裏空間及び壁裏空間へ冷却空気又は加温空気を供給する空調機と、前記壁材の上部又は前記天井材に開閉可能に設けられ前記壁裏空間を経由して供給された冷却空気を前記室内空間へ噴き出し可能な上部噴き出し口と、前記壁材の下部又は床材に開閉可能に設けられ前記壁裏空間を経由して供給された加温空気を前記室内空間へ噴き出し可能な下部噴き出し口を備えることを特徴とするものである。 As means for effectively solving the technical problem described above, a radiant cooling and heating system according to the invention of claim 1 is defined by a ceiling back space defined on the back side of the ceiling material and a back side of the wall material.

It is characterized by comprising a lower outlet from which the heated air supplied via the wall space can be discharged into the indoor space.
このように構成すれば、空調機を駆動させると、天井裏空間及びこれに連通した壁裏空間へ冷却空気又は加温空気が供給されるので、それによる冷熱又は温熱が天井材及び壁材を介して室内空間へ放射されることによって、放射冷暖房が行われる。 According to this configuration, when the air conditioner is driven, cooling air or warm air is supplied to the ceiling back space and the back wall space communicating with the ceiling space. Radiant cooling and heating are performed by radiating through the indoor space.
そして冷房の場合は、壁材の上部又は天井材に開設された上部噴き出し口を開放すると共に壁材の下部又は床材に開設された下部噴き出し口を閉塞することによって、空調機による冷却空気が上部噴き出し口を通じて室内空間の上部へ流入するので、天井からの冷熱放射による放射冷房の立ち上がりが補われると共に、頭寒足熱となる温度分布による快適な環境が創出される。しかも室内空間の温暖湿潤空気が空調機に取り込まれて冷却される過程で、空気中の水蒸気が潜熱と共に除去され、乾燥冷却された空気が前記上部噴き出し口を通じて室内空間へ供給されるので、室内空間の潜熱負荷も減少する。 And in the case of cooling, the upper air outlet opened in the upper part of the wall material or the ceiling material is opened and the lower air outlet opened in the lower part of the wall material or the floor material is closed, so that the cooling air by the air conditioner is Since it flows into the upper part of the indoor space through the upper outlet, the rise of the radiant cooling due to the cold radiation from the ceiling is supplemented, and a comfortable environment is created due to the temperature distribution that becomes the cold head heat. Moreover, in the process where warm and humid air in the indoor space is taken into the air conditioner and cooled, the water vapor in the air is removed together with the latent heat, and the dried and cooled air is supplied to the indoor space through the upper outlet, The latent heat load of the space is also reduced.
また、暖房の場合は、逆に上部噴き出し口を閉塞すると共に下部噴き出し口を開放することによって、空調機による加温空気が壁裏空間及び下部噴き出し口を通じて室内空間の下部へ流入するので、天井からの温熱放射による放射暖房の立ち上がりが補われると共に、頭熱足寒となる不快な温度分布が解消されて快適な環境が創出される。 In the case of heating, conversely, by closing the upper outlet and opening the lower outlet, the heated air from the air conditioner flows into the lower part of the indoor space through the back wall space and the lower outlet. The rise of the radiant heating due to the thermal radiation from the water is compensated, and the uncomfortable temperature distribution that becomes cold in the head is eliminated and a comfortable environment is created.

このように構成すれば、上部噴き出し口から室内空間へ噴き出す冷却空気の風量及び下部噴き出し口から室内空間へ噴き出す加温空気の風量が任意に調整可能であると共に、この風量調整によって、天井裏空間から空調機へ直接取り込まれる空気と、室内空間から空調機へ取り込まれる空気の割合が変化するので、天井材及び壁材を介して室内空間へ放射されることによる放射冷暖房効果と、冷却空気又は加温空気の噴き出しによる室内対流による冷暖房効果のバランスや、室内空間の気流感を適宜に調整することができる。 With this configuration, the amount of cooling air blown from the upper outlet to the indoor space and the amount of warm air blown from the lower outlet to the indoor space can be arbitrarily adjusted. Since the ratio of the air directly taken into the air conditioner from the air and the ratio of the air taken into the air conditioner from the indoor space changes, the effect of radiant cooling and heating by radiating into the indoor space through the ceiling material and the wall material, cooling air or It is possible to appropriately adjust the balance of the cooling / heating effect due to indoor convection caused by the ejection of heated air and the feeling of airflow in the indoor space.

In addition to the radiant cooling and heating effect by radiating to the space, the cooling air or the heating air in the ceiling back space and the wall space that communicates with it is blown into the indoor space, so that The rise is compensated for and improved, while humid air in the indoor space is taken into the air conditioner during cooling, while dry / cooled air is blown out into the indoor space, ensuring an appropriate dehumidification environment and improving the air flow feeling in the indoor space Can be achieved.
以下、本発明に係る放射冷暖房システムの好ましい実施の形態について、図面を参照しながら説明する。 Hereinafter, preferred embodiments of a radiant cooling and heating system according to the present invention will be described with reference to the drawings.
まず図１において、参照符号１は鉄骨・鉄筋コンクリート造りの建築物の躯体であって、１１は躯体スラブ、１２は躯体側壁である。躯体スラブ１１の下側には不図示の吊りボルトや格子状に組まれた天井下地材などを介して天井材２が取り付けられており、躯体側壁１２には、不図示の間柱状のスペーサを介して壁装パネル３が取り付けられており、これら天井材２及び壁装パネル３によって、室内空間Ｓ１が形成されている。なお、壁装パネル３は請求項１に記載された壁材に相当する。 First, in FIG. 1, reference numeral 1 is a frame of a steel frame / reinforced concrete building, 11 is a frame slab, and 12 is a frame side wall. A ceiling material 2 is attached to the lower side of the housing slab 11 via suspension bolts (not shown) or ceiling base materials assembled in a lattice shape, and a columnar spacer (not shown) is attached to the housing side wall 12. A wall panel 3 is attached through the ceiling material 2 and the wall panel 3 to form an indoor space S1. The wall panel 3 corresponds to the wall material described in claim 1.
天井材２は、水蒸気の通過を許容する透湿性及び水蒸気を吸収する吸湿性に優れた多孔質材料からなるものであって、例えば石膏ボードからなるものが好適に用いられる。一方、壁装パネル３も石膏ボード等からなるものであって、その表面には不図示のクロス壁紙などの装飾材が貼着されている。 The ceiling material 2 is made of a porous material excellent in moisture permeability that allows passage of water vapor and moisture absorption that absorbs water vapor. For example, a material made of gypsum board is preferably used. On the other hand, the wall panel 3 is also made of gypsum board or the like, and a decorative material such as a cross wallpaper (not shown) is stuck on the surface thereof.
天井材２の裏側、すなわち天井材２と躯体スラブ１１の間には天井裏空間Ｓ２が画成されており、壁装パネル３の裏側、すなわち壁装パネル３と躯体側壁１２の間には壁裏空間Ｓ３が画成されており、この壁裏空間Ｓ３の上部は、天井裏空間Ｓ２に連通している。なお、躯体スラブ１１の下面又は上面と、躯体側壁１２の内側面には、それぞれ断熱材１３が取り付けられており、この断熱材１３によって、天井裏空間Ｓ２及び壁裏空間Ｓ３が適度に断熱されている。 A ceiling back space S2 is defined between the back side of the ceiling material 2, that is, between the ceiling material 2 and the frame slab 11, and a wall is provided between the back side of the wall panel 3, that is, between the wall panel 3 and the frame side wall 12. A back space S3 is defined, and an upper portion of the wall back space S3 communicates with the ceiling back space S2. A heat insulating material 13 is attached to the lower surface or the upper surface of the housing slab 11 and the inner surface of the housing side wall 12, and the ceiling back space S2 and the wall back space S3 are appropriately insulated by the heat insulating material 13. ing.
参照符号４はダクト式の空調機で、図２に示すように、天井裏空間Ｓ２に設置された室内機４１と、躯体１の外部に設置された室外機４２を備え、室内機４１と室外機４２の間で、流体を液相−気相の可逆変化を伴いながら循環させることによって、室内機４１から室外機４２へ熱を搬送し（冷房）、あるいは室外機４２から室内機４１へ熱を搬送する（暖房）ヒートポンプ機能を奏するものである。 Reference numeral 4 denotes a duct-type air conditioner, which includes an indoor unit 41 installed in the ceiling space S2 and an outdoor unit 42 installed outside the housing 1, as shown in FIG. Heat is transferred from the indoor unit 41 to the outdoor unit 42 (cooling) or circulated between the units 42 with a reversible change of the liquid phase to the gas phase, or heat is transferred from the outdoor unit 42 to the indoor unit 41. (Heating) heat pump function.
空調機４の室内機４１は、その吸気口４１ａが天井材２に開設された開口部２１の近傍にあって、天井裏空間Ｓ２内の空気と室内空間Ｓ１内の空気の双方を取り込むようになっている。また、室内機４１からは空調空気を吐出する複数のダクト４３が延びており、天井裏空間Ｓ２に顕著な旋回流を生じるように、各ダクト４３の吐気口４３ａが、例えば躯体側壁１２の異なる面の近傍で各面と略平行となる方向を向いている。 The indoor unit 41 of the air conditioner 4 has an intake port 41a in the vicinity of the opening 21 formed in the ceiling material 2, and takes in both the air in the ceiling back space S2 and the air in the indoor space S1. It has become. Further, a plurality of ducts 43 for discharging conditioned air extend from the indoor unit 41, and the air outlets 43a of the respective ducts 43 are different from each other on the housing side wall 12, for example, so as to generate a noticeable swirling flow in the ceiling space S2. It faces in a direction that is substantially parallel to each surface in the vicinity of the surface.
壁装パネル３の上部には、開閉可能な上部噴き出し口５が一カ所以上に開設されており、壁装パネル３の下部には、開閉可能な下部噴き出し口６が一カ所以上に開設されている。これら上部噴き出し口５及び下部噴き出し口６は、例えば開閉及び風量調節可能なダンパーを有する空調用レジスターからなるものとすることができる。 At the top of the wall panel 3, there are one or more upper outlets 5 that can be opened and closed. At the lower part of the wall panel 3, there are one or more lower outlets 6 that can be opened and closed. Yes. The upper outlet 5 and the lower outlet 6 can be made of, for example, air-conditioning registers having dampers that can be opened and closed and the air volume can be adjusted.
また、上部噴き出し口５及び下部噴き出し口６は、開閉及び風量調節可能なダンパーが空調機４に内蔵された制御装置からの信号によって駆動が制御されるアクチュエータによって動作するものであっても良い。すなわちこの場合、上部噴き出し口５及び下部噴き出し口６の動作は、例えば室内の任意の箇所に設置されたリモコン装置７からの操作信号によって、前記制御装置を介して空調機４の駆動と共に制御されるものであり、例えば冷房運転においては、上部噴き出し口５が開放されてその開度が適宜に制御されると共に下部噴き出し口６が閉塞され、暖房運転においては、逆に上部噴き出し口５が閉塞されると共に下部噴き出し口６が開放されてその開度が適宜に制御されるようにすることができる。 Further, the upper outlet 5 and the lower outlet 6 may be operated by an actuator whose driving is controlled by a signal from a control device built in the air conditioner 4 with a damper capable of opening and closing and adjusting the air volume. That is, in this case, the operations of the upper outlet 5 and the lower outlet 6 are controlled together with the driving of the air conditioner 4 via the control device, for example, by an operation signal from a remote control device 7 installed at an arbitrary place in the room. For example, in the cooling operation, the upper outlet 5 is opened and its opening degree is appropriately controlled and the lower outlet 6 is closed. In the heating operation, the upper outlet 5 is closed. At the same time, the lower outlet 6 can be opened and its opening degree can be appropriately controlled.
以上のように構成された実施の形態の放射冷房システムによれば、夏季の冷房においては、例えばユーザーがリモコン装置７を操作することによって空調機４を冷房運転させると、図３に示すように、まず天井裏空間Ｓ２及びこれに連通した壁裏空間Ｓ３へ冷却空気ＣＡが供給され、すなわち天井裏空間Ｓ２及び壁裏空間Ｓ３の空気が冷却される。躯体スラブ１１の下面又は上面と、躯体側壁１２の内側面には、それぞれ断熱材１３（図１参照）が取り付けられているため、天井裏空間Ｓ２及び壁裏空間Ｓ３の空気の冷却が効率良く行われると共に、上階の床面などに結露が発生するのを有効に防止することができる。 According to the radiation cooling system of the embodiment configured as described above, when the air conditioner 4 is cooled by operating the remote control device 7 in the summer cooling, for example, as shown in FIG. First, the cooling air CA is supplied to the ceiling space S2 and the wall space S3 communicating with the ceiling space S2, that is, the air in the ceiling space S2 and the wall space S3 is cooled. Since the heat insulating material 13 (refer FIG. 1) is attached to the lower surface or upper surface of the housing slab 11 and the inner surface of the housing side wall 12, the cooling of the air in the ceiling back space S2 and the back space S3 is efficient. As well as being performed, it is possible to effectively prevent the occurrence of condensation on the floor surface of the upper floor.
そして、天井裏空間Ｓ２及び壁裏空間Ｓ３内の温度が低下して行くにつれて、天井裏空間Ｓ２及び壁裏空間Ｓ３内の冷却空気ＣＡとの熱交換によって天井材２及び壁装パネル３も冷却されるので、この天井材２及び壁装パネル３から室内空間Ｓ１への冷熱放射ＣＲによって放射冷房が行われる。言い換えれば、室内空間Ｓ１の顕熱が天井材２及び壁装パネル３から天井裏空間Ｓ２及び壁裏空間Ｓ３を介して空調機４に取り込まれ、そのヒートポンプ機能により躯体１の外部へ放出される。 Then, as the temperature in the ceiling space S2 and the wall space S3 decreases, the ceiling material 2 and the wall panel 3 are also cooled by heat exchange with the cooling air CA in the ceiling space S2 and the wall space S3. Therefore, radiant cooling is performed by the cooling radiation CR from the ceiling material 2 and the wall panel 3 to the indoor space S1. In other words, the sensible heat of the indoor space S1 is taken into the air conditioner 4 from the ceiling material 2 and the wall panel 3 through the ceiling back space S2 and the wall back space S3, and is released to the outside of the housing 1 by its heat pump function. .
ここで、図３に示すように、壁装パネル３の上部に開設された上部噴き出し口５を開放すると共に壁装パネル３の下部に開設された下部噴き出し口６を閉塞することによって、空調機４により冷却された天井裏空間Ｓ２内の冷却空気ＣＡが上部噴き出し口５を通じて室内空間Ｓ１の上部へ流入するので、天井材２及び壁装パネル３からの冷熱放射ＣＲによる室内空間Ｓ１の放射冷房の立ち上がりの悪さが改善されると共に、この冷熱放射ＣＲと上部噴き出し口５から流入する冷却空気ＣＡとの協働によって、図３に温度分布を濃淡で示すように（濃いほど低温）、頭熱足寒となるような不快な温度分布が解消される。なお、このような上部噴き出し口５及び下部噴き出し口６の開閉動作は、先に説明したように、例えばリモコン装置７からの操作信号によって、空調機４の運転と共に制御されるものとすることができる。 Here, as shown in FIG. 3, an air conditioner is opened by opening the upper outlet 5 opened at the upper part of the wall panel 3 and closing the lower outlet 6 opened at the lower part of the wall panel 3. Since the cooling air CA in the ceiling space S2 cooled by the air 4 flows into the upper part of the indoor space S1 through the upper outlet 5, the radiant cooling of the indoor space S1 by the thermal radiation CR from the ceiling material 2 and the wall panel 3 As shown in FIG. 3, the temperature distribution is shown by shading (the lower the temperature is, the lower the temperature is) due to the cooperation between the cooling heat radiation CR and the cooling air CA flowing in from the upper outlet 5. An unpleasant temperature distribution that causes a cold foot is eliminated. It should be noted that such opening and closing operations of the upper outlet 5 and the lower outlet 6 are controlled together with the operation of the air conditioner 4 by an operation signal from the remote control device 7, for example, as described above. it can.
一方、室内空間Ｓ１内の温暖湿潤空気のもつ潜熱は、空気中の水蒸気と共に、透湿性に優れた多孔質の天井材２を天井裏空間Ｓ２内へ透過し、空調機４の室内機４１に取り込まれる。また、天井材２は吸湿性も有するため、室内空間Ｓ１内の空気のもつ潜熱（水蒸気）の一部は、この天井材２にも吸収される。すなわち、室内空間Ｓ１から天井材２への吸湿量と、天井材２から天井裏空間Ｓ２内への放湿量の差が、天井材２への蓄湿量となる。また、室内機４１の吸気口４１ａに取り込まれる空気には、室内空間Ｓ１から天井材２の開口部２１を通じて取り込まれるものも含まれる。 On the other hand, the latent heat of the warm humid air in the indoor space S1 passes through the porous ceiling material 2 excellent in moisture permeability into the ceiling back space S2 together with the water vapor in the air, and reaches the indoor unit 41 of the air conditioner 4. It is captured. Moreover, since the ceiling material 2 has a hygroscopic property, part of the latent heat (water vapor) of the air in the indoor space S1 is also absorbed by the ceiling material 2. That is, the difference between the moisture absorption amount from the indoor space S1 to the ceiling material 2 and the moisture release amount from the ceiling material 2 into the ceiling back space S2 is the moisture storage amount to the ceiling material 2. In addition, the air taken into the air inlet 41a of the indoor unit 41 includes air taken from the indoor space S1 through the opening 21 of the ceiling member 2.
そして、天井裏空間Ｓ２内の空気及び室内空間Ｓ１内の空気が空調機４の室内機４１に取り込まれて冷却される際には、空気に含まれる水蒸気が飽和して凝縮され、図２に示すようにドレン水ＤＷとなって躯体１の外部へ排出されるので、ダクト４３を介して天井裏空間Ｓ２へ噴出する冷却空気ＣＡは相対湿度が低いものとなっている。このため天井材２に吸収された水蒸気が天井裏空間Ｓ２に効率良く放出（放湿）され、その後、室内機４１内に取り込まれて凝縮され、ドレン水ＤＷとして除去されることになる。このとき、室内機４１内の熱交換器で水蒸気が液化する際の潜熱は、空調機４のヒートポンプ機構により室外機４２に運ばれ、室外機４２内の熱交換器から躯体１の外部へ放出される。すなわちこのような過程で室内空間Ｓ１内の水蒸気が除去されると共に、天井裏空間Ｓ２内の相対湿度の低い冷却空気ＣＡが壁装パネル３の上部噴き出し口５から室内空間Ｓ１へ流入するため、室内空間Ｓ１の潜熱負荷も減少する。 When the air in the ceiling space S2 and the air in the indoor space S1 are taken into the indoor unit 41 of the air conditioner 4 and cooled, the water vapor contained in the air is saturated and condensed. As shown, since the drain water DW is discharged to the outside of the housing 1, the cooling air CA ejected to the ceiling space S <b> 2 through the duct 43 has a low relative humidity. For this reason, the water vapor absorbed by the ceiling material 2 is efficiently released (moisture released) into the ceiling space S2, and then taken into the indoor unit 41, condensed, and removed as drain water DW. At this time, the latent heat generated when the water vapor is liquefied by the heat exchanger in the indoor unit 41 is carried to the outdoor unit 42 by the heat pump mechanism of the air conditioner 4 and released from the heat exchanger in the outdoor unit 42 to the outside of the housing 1. Is done. That is, in this process, the water vapor in the indoor space S1 is removed, and the cooling air CA having a low relative humidity in the ceiling space S2 flows from the upper outlet 5 of the wall panel 3 into the indoor space S1. The latent heat load in the indoor space S1 is also reduced.
また、図２に示すように空調機４の複数のダクト４３の吐気口４３ａによって、天井裏空間Ｓ２に旋回流が形成されるため、天井裏空間Ｓ２の温度分布が一様になり、天井材２に温度ムラができにくくなるので、天井材２から室内空間Ｓ１への冷熱放射ＣＲの均一化を図ることができる。 In addition, as shown in FIG. 2, a swirl flow is formed in the ceiling space S2 by the air outlets 43a of the plurality of ducts 43 of the air conditioner 4, so that the temperature distribution in the ceiling space S2 becomes uniform, and the ceiling material. 2 is less likely to cause temperature unevenness, so that the cold radiation CR from the ceiling material 2 to the indoor space S1 can be made uniform.
また、上部噴き出し口５の開度を調整することによって、この上部噴き出し口５から室内空間Ｓ１への冷却空気ＣＡの風量を調整することで、室内空間Ｓ１における気流感を適宜に調整することができると共に、この風量調整に対応して、室内空間Ｓ１から天井材２の開口部２１を通じて空調機４の室内機４１の吸気口４１ａへ取り込まれる空気の割合も変化するので、天井材２及び壁装パネル３から室内空間Ｓ１への冷熱放射ＣＲによる放射冷房効果と、上部噴き出し口５からの冷却空気ＣＡの噴き出しによる室内対流による冷房効果のバランスを適切に調整することができる。 In addition, by adjusting the opening degree of the upper ejection port 5 and adjusting the air volume of the cooling air CA from the upper ejection port 5 to the indoor space S1, it is possible to appropriately adjust the air flow feeling in the indoor space S1. In addition, the ratio of the air taken into the air inlet 41a of the indoor unit 41 of the air conditioner 4 from the indoor space S1 through the opening 21 of the ceiling material 2 also changes corresponding to this air volume adjustment. It is possible to appropriately adjust the balance between the radiant cooling effect by the cooling radiation CR from the mounting panel 3 to the indoor space S1 and the cooling effect by the indoor convection by the ejection of the cooling air CA from the upper ejection port 5.
次に、冬季の暖房においては、例えばユーザーがリモコン装置７を操作することによって空調機４を暖房運転させると、図４に示すように、まず天井裏空間Ｓ２及びこれに連通した壁裏空間Ｓ３へ加温空気ＷＡが供給され、すなわち天井裏空間Ｓ２及び壁裏空間Ｓ３の空気が加温される。躯体スラブ１１の下面又は上面と、躯体側壁１２の内側面には、それぞれ断熱材１３（図１参照）が取り付けられているため、天井裏空間Ｓ２及び壁裏空間Ｓ３の空気の加温が効率良く行われる。 Next, in heating in winter, for example, when the user operates the air conditioner 4 by operating the remote controller 7, for example, as shown in FIG. 4, first, the ceiling space S2 and the wall space S3 communicating with the ceiling space S2 are firstly provided. The heated air WA is supplied, that is, the air in the ceiling space S2 and the wall space S3 is heated. Since the heat insulating material 13 (see FIG. 1) is attached to the lower surface or upper surface of the housing slab 11 and the inner surface of the housing side wall 12, heating of the air in the ceiling back space S2 and the back space S3 is efficient. Well done.
そして、天井裏空間Ｓ２及び壁裏空間Ｓ３内の温度が上昇して行くにつれて、天井裏空間Ｓ２及び壁裏空間Ｓ３内の加温空気ＷＡとの熱交換によって天井材２及び壁装パネル３も加温されるので、この天井材２及び壁装パネル３から室内空間Ｓ１への温熱放射ＷＲによって放射暖房が行われる。 As the temperature in the ceiling back space S2 and the wall back space S3 rises, the ceiling material 2 and the wall panel 3 are also exchanged by heat exchange with the heated air WA in the ceiling back space S2 and the wall back space S3. Since it is heated, radiant heating is performed by the thermal radiation WR from the ceiling material 2 and the wall panel 3 to the indoor space S1.
ここで、図４に示すように、壁装パネル３の下部に開設された下部噴き出し口６を開放すると共に壁装パネル３の上部に開設された上部噴き出し口５を閉塞することによって、空調機４により加温された天井裏空間Ｓ２内の加温空気ＷＡが壁裏空間Ｓ３及び下部噴き出し口６を通じて室内空間Ｓ１の下部へ流入するので、天井材２及び壁装パネル３からの温熱放射ＷＲによる室内空間Ｓ１の放射暖房の立ち上がりの悪さが改善されると共に、この温熱放射ＷＲと下部噴き出し口６から流入する加温空気ＷＡとの協働によって、図４に温度分布を濃淡で示すように（濃いほど高温）、頭熱足寒となるような不快な温度分布が解消される。なお、下部噴き出し口６から室内空間Ｓ１の下部へ流入した加温空気ＷＡは、図中に破線矢印で示すように床に沿って減速しながら比重差によって上昇しながら撹拌され、やがて天井材２の開口部２１から空調機４の室内機４１の吸気口４１ａへ取り込まれることになる。 Here, as shown in FIG. 4, by opening the lower outlet 6 opened at the lower part of the wall panel 3 and closing the upper outlet 5 opened at the upper part of the wall panel 3, the air conditioner Since the heated air WA in the ceiling back space S2 heated by the air 4 flows into the lower part of the indoor space S1 through the wall back space S3 and the lower outlet 6, the thermal radiation WR from the ceiling material 2 and the wall panel 3 As shown in FIG. 4, the temperature distribution is shown in shades by the cooperation between the thermal radiation WR and the heated air WA flowing from the lower outlet 6. (The darker the temperature is, the higher the temperature is). The heated air WA that has flowed into the lower portion of the indoor space S1 from the lower outlet 6 is agitated while rising due to the difference in specific gravity while decelerating along the floor as indicated by the broken line arrows in the figure, and eventually the ceiling material 2 Are taken into the air inlet 41a of the indoor unit 41 of the air conditioner 4.
また、図２に示すように空調機４の複数のダクト４３の吐気口４３ａによって、天井裏空間Ｓ２に旋回流が形成されるため、天井裏空間Ｓ２の温度分布が一様になり、天井材２に温度ムラができにくくなるので、天井材２から室内空間Ｓ１への温熱放射ＷＲの均一化を図ることができる。 In addition, as shown in FIG. 2, a swirl flow is formed in the ceiling space S2 by the air outlets 43a of the plurality of ducts 43 of the air conditioner 4, so that the temperature distribution in the ceiling space S2 becomes uniform, and the ceiling material. 2 is less likely to cause temperature unevenness, so that the thermal radiation WR from the ceiling material 2 to the indoor space S1 can be made uniform.
また、下部噴き出し口６の開度を調整することによって、この下部噴き出し口６から室内空間Ｓ１への加温空気ＷＡの風量を調整することで、室内空間Ｓ１における気流感を適宜に調整することができると共に、この風量調整に対応して、室内空間Ｓ１から天井材２の開口部２１を通じて空調機４の室内機４１の吸気口４１ａへ取り込まれる空気の割合も変化するので、天井材２及び壁装パネル３から室内空間Ｓ１への温熱放射ＷＲによる放射暖房効果と、下部噴き出し口６からの加温空気ＷＡの噴き出しによる室内対流による暖房効果のバランスを適切に調整することができる。 Further, by adjusting the opening of the lower outlet 6 and adjusting the air volume of the heated air WA from the lower outlet 6 to the indoor space S1, the airflow feeling in the indoor space S1 can be adjusted appropriately. In response to this air volume adjustment, the ratio of the air taken into the air inlet 41a of the indoor unit 41 of the air conditioner 4 from the indoor space S1 through the opening 21 of the ceiling material 2 also changes. The balance between the radiant heating effect by the thermal radiation WR from the wall panel 3 to the indoor space S1 and the heating effect by the indoor convection by the ejection of the heated air WA from the lower outlet 6 can be adjusted appropriately.
なお、室内空間Ｓ１を放射冷暖房の環境とするには、室内空間Ｓ１の温度と天井材２の表面温度の温度差をある程度保つ必要があるため、天井材２は、熱抵抗が0.2m2・K/W以下のものを用い、上部噴き出し口５又は下部噴き出し口６から室内空間Ｓ１へ流入させる風量を、床面積当たり0.01m3/s以下とすることが好ましい。 In order to make the indoor space S1 an environment for radiant cooling and heating, the temperature difference between the temperature of the indoor space S1 and the surface temperature of the ceiling material 2 needs to be maintained to some extent. Therefore, the ceiling material 2 has a thermal resistance of 0.2 m 2. It is preferable to use K / W or less, and the amount of air flowing into the indoor space S1 from the upper outlet 5 or the lower outlet 6 is 0.01 m 3 / s or less per floor area.
また、上述した実施の形態では、上部噴き出し口５を壁装パネル３の上部に開設し、下部噴き出し口６を壁装パネル３の下部に開設したが、上部噴き出し口５は天井材２に開設しても良く、下部噴き出し口６は、躯体スラブ１１の上に設置した不図示の床材に開設して、空調機４により加温された天井裏空間Ｓ２内の加温空気ＷＡが壁裏空間Ｓ３を介して前記躯体スラブ１１と床材の間の不図示の床下隙間へ導入され、そこから床材の下部噴き出し口を通じて室内空間Ｓ１の下部へ噴き出されるようにしても良い。 In the above-described embodiment, the upper outlet 5 is opened at the upper part of the wall panel 3 and the lower outlet 6 is opened at the lower part of the wall panel 3. However, the upper outlet 5 is opened in the ceiling member 2. Alternatively, the lower outlet 6 is opened on a floor material (not shown) installed on the housing slab 11, and the heated air WA in the ceiling space S2 heated by the air conditioner 4 is behind the wall. It may be introduced into an underfloor gap (not shown) between the frame slab 11 and the floor material via the space S3, and then ejected from there through the lower ejection port of the floor material to the lower portion of the indoor space S1.
