Description

本発明は、主として輻射パネルによる放熱又は吸熱により暖房又は冷房を行う輻射式（放射式）空気調和機（以降、「輻射式空調機」と称呼される場合がある）に関する。特に、本発明は、輻射パネルが水平面と交差する角度にて配置される縦型の輻射式空調機に関する。   The present invention relates to a radiation type air conditioner (hereinafter sometimes referred to as “radiation type air conditioner”) that performs heating or cooling mainly by heat radiation or heat absorption by a radiation panel. In particular, the present invention relates to a vertical radiation type air conditioner in which a radiation panel is arranged at an angle intersecting a horizontal plane.

当該技術分野においては、温風又は冷風を吹き出すことによって室内空間を暖房又は冷房する空気調和機（以降、「送風式空調機」と称呼される場合がある）が広く普及している。しかしながら、送風式空調機による暖房又は冷房時には室内空間における気流速度が高く、例えば、当該空間に滞在する人間が温風又は冷風を不快に感じたり、肌の乾燥を招いたりする等の問題を生ずる場合があった。   In this technical field, air conditioners that heat or cool indoor spaces by blowing warm air or cold air (hereinafter sometimes referred to as “air blower air conditioners”) are widely used. However, the airflow rate in the indoor space is high during heating or cooling by the air blower type air conditioner, and for example, a person staying in the space feels hot air or cold air uncomfortable or causes dry skin. There was a case.

そこで、昨今では、高い輻射能力（放射能力）を有する輻射パネル（伝熱管等の熱交換器が露出しているタイプ等を含む）に熱媒体（「温冷媒」と称呼される場合もある）を供給して室内空間を暖房又は冷房する輻射式空調機への関心が高まっており、また普及も進みつつある。輻射式空調機は、主として輻射パネルによる放熱又は吸熱により暖房又は冷房を行うため、送風式空調機において懸念される上述したような問題は基本的には生じない。従って、輻射式空調機は、送風式空調機と比較して快適性が高い空調機としての評価を獲得している。   Therefore, in recent years, a heat medium (sometimes referred to as “warm refrigerant”) is used for a radiation panel (including a type in which a heat exchanger such as a heat transfer tube is exposed) having high radiation ability (radiation ability). There is a growing interest in radiant air conditioners that heat or cool indoor spaces by supplying air and is also spreading. Since the radiant air conditioner performs heating or cooling mainly by heat radiation or heat absorption by the radiant panel, the above-described problems that are a concern in the blower air conditioner basically do not occur. Therefore, the radiation type air conditioner has gained an evaluation as an air conditioner having higher comfort than the blower type air conditioner.

しかしながら、輻射式空調機には、送風式空調機とは異なる固有の問題も存在する。具体的には、冷房時には床付近に冷気が滞留し易く、当該空間に滞在する人間が足元付近に寒さを感じ易いという問題がある。一方、暖房時には天井付近に暖気が滞留し易く且つ床付近に冷気が滞留し易く、当該空間に滞在する人間が足元付近に寒さを感じ易い。更には、当該空間に滞在する人間が頭部付近に暑さを感じ易くなるという問題もある。   However, radiation-type air conditioners also have inherent problems that differ from blower-type air conditioners. Specifically, there is a problem that cold air tends to stay near the floor during cooling, and a person staying in the space tends to feel cold near the feet. On the other hand, during heating, warm air tends to stay near the ceiling and cool air tends to stay near the floor, and a person staying in the space tends to feel cold near the feet. Furthermore, there is a problem that a person staying in the space can easily feel the heat near the head.

上記のような問題は以下のようなメカニズムによって生ずると考えられる。先ず、冷房時には、図６に示すように、熱媒体（一般的には、冷水）により、室温よりも低い温度にまで輻射パネル１１が冷却され、当該輻射パネル１１の表面付近の空気が冷却されて冷気となる。その結果、当該空気（冷気）の比重が周囲の空気よりも大きくなるため、当該冷気が輻射パネルの表面に沿って下降する（下向きの白抜き矢印）。即ち、下降方向の自然対流が生ずる。当該自然対流の流速は低く、最終的に室内空間の床付近（点線の楕円によって囲まれた領域）に冷気が滞留している状態が安定化する。   The above problem is considered to be caused by the following mechanism. First, at the time of cooling, as shown in FIG. 6, the radiation panel 11 is cooled to a temperature lower than room temperature by a heat medium (generally cold water), and the air near the surface of the radiation panel 11 is cooled. It becomes cold. As a result, the specific gravity of the air (cold air) becomes larger than that of the surrounding air, so that the cold air descends along the surface of the radiation panel (downward white arrow). That is, natural convection in the downward direction occurs. The flow rate of the natural convection is low, and finally the state where the cold air stays near the floor of the indoor space (the region surrounded by the dotted ellipse) is stabilized.

逆に、暖房時には、図７に示すように、熱媒体（一般的には、温水）により、室温よりも高い温度にまで輻射パネル１１が加熱され、当該輻射パネル１１の表面付近の空気が加熱されて暖気となる。その結果、当該空気（暖気）の比重が周囲の空気よりも小さくなるため、当該暖気が輻射パネルの表面に沿って上昇する（上向きの白抜き矢印）。即ち、上昇方向の自然対流が生ずる。当該自然対流の流速もまた低く、最終的に室内空間の天井付近（点線の楕円によって囲まれた領域）に暖気が滞留している状態が安定化する。これに伴い、室内空間の床付近には相対的に低い温度を有する空気が滞留している状態が安定化する（図示せず）。   Conversely, during heating, as shown in FIG. 7, the radiant panel 11 is heated to a temperature higher than room temperature by a heat medium (generally, hot water), and the air near the surface of the radiant panel 11 is heated. Being warm. As a result, since the specific gravity of the air (warm air) is smaller than that of the surrounding air, the warm air rises along the surface of the radiation panel (upward white arrow). That is, ascending natural convection occurs. The flow velocity of the natural convection is also low, and finally the state where warm air stays near the ceiling of the indoor space (the region surrounded by the dotted ellipse) is stabilized. Accordingly, the state in which air having a relatively low temperature stays near the floor of the indoor space is stabilized (not shown).

そこで、当該技術分野においては、例えば、（ファンによって）室内空間から輻射パネル内に空気を吸入して当該輻射パネル内に配設された熱交換器（伝熱管）と熱交換させた後に、当該空気を補助空気として上記自然対流に吹き付ける技術が提案されている（例えば、特許文献１を参照）。より具体的には、冷房時には輻射パネルの上部から空気を吸入して当該輻射パネル内に配設された伝熱管との熱交換により当該空気を冷却して冷気とし、当該冷気を輻射パネルの下部から室内空間の中央側に向けて（即ち、輻射パネルの表面に垂直な方向に）補助空気として吹き出す。これにより、上述した冷気の下降方向の自然対流に当該補助空気を強制的に混合して加勢し、結果として、室内空間の床付近における冷気の滞留を効果的に抑制する。   Therefore, in this technical field, for example, after air is sucked into the radiant panel from the indoor space (by a fan) and heat exchanged with a heat exchanger (heat transfer tube) disposed in the radiant panel, A technique for blowing air to the natural convection as auxiliary air has been proposed (see, for example, Patent Document 1). More specifically, at the time of cooling, air is sucked from the upper part of the radiant panel, and the air is cooled to cool air by heat exchange with the heat transfer tubes arranged in the radiant panel, and the cool air is converted into the lower part of the radiant panel To the center of the indoor space (that is, in a direction perpendicular to the surface of the radiation panel) as auxiliary air. Thereby, the auxiliary air is forcibly mixed with the natural convection in the descending direction of the cold air described above and is urged, and as a result, the stay of the cold air near the floor of the indoor space is effectively suppressed.

逆に、暖房時には輻射パネルの下部から空気を吸入して当該輻射パネル内に配設された熱交換器との熱交換により当該空気を加熱して暖気とし、当該暖気を輻射パネルの上部から室内空間の中央側に向けて（即ち、輻射パネルの表面に垂直な方向に）補助空気として吹き出す。これにより、上述した暖気の上昇方向の自然対流に当該補助空気を強制的に混合して加勢し、結果として、室内空間の天井付近における暖気の滞留を効果的に抑制する。   Conversely, during heating, air is sucked from the lower part of the radiant panel, and the air is heated to warm air by heat exchange with the heat exchanger disposed in the radiant panel. It blows out as auxiliary air toward the center of the space (that is, in a direction perpendicular to the surface of the radiation panel). Thereby, the auxiliary air is forcibly mixed and energized in the natural convection in the upward direction of the warm air described above, and as a result, the stay of warm air near the ceiling of the indoor space is effectively suppressed.

しかしながら、上述した従来技術に係る輻射式空調機においては、補助空気を吹き出すことによって自然対流を強制的に加勢するため、室内空間における空気の流動（気流）が生じたり、速まったりする。その結果、室内空間における気流速度が高いために当該空間に滞在する人間が気流を不快に感じる等の問題が基本的には生じないという輻射式空調機の本来の利点が損なわれる虞がある。   However, in the radiant air conditioner according to the above-described prior art, natural convection is forcibly added by blowing out auxiliary air, and thus air flow (airflow) in the indoor space is generated or accelerated. As a result, since the air velocity in the indoor space is high, there is a possibility that the original advantage of the radiant air conditioner that a person staying in the space feels uncomfortable with the air flow basically does not occur.

更に、上述した従来技術に係る輻射式空調機においては、（ファンによって）室内空間から輻射パネル内に空気が吸入され、当該輻射パネル内に配設された熱交換器と当該空気との間で熱交換が行われる。即ち、空気と熱交換器との間の強制対流伝熱現象により、冷房時には空気が冷却され、暖房時には空気が加熱される。従って、熱交換器に投入されるエネルギー量が一定である場合、輻射パネルの温度は、上記強制対流伝熱現象が起こらない状態と比べて、冷房時には上昇し、暖房時には低下する。即ち、熱交換器に投入されるエネルギー量が一定である場合、上記のように（ファンによる）強制的な熱交換を行うことにより、輻射パネルによる吸熱量及び放熱量（伝熱量）が減少する。その結果、輻射式空調機の本来の輻射による冷房又は暖房の効果が小さくなる。   Further, in the above-described radiant air conditioner according to the prior art, air is sucked into the radiant panel from the indoor space (by a fan), and between the heat exchanger disposed in the radiant panel and the air. Heat exchange takes place. That is, due to the forced convection heat transfer phenomenon between the air and the heat exchanger, the air is cooled during cooling and the air is heated during heating. Therefore, when the amount of energy input to the heat exchanger is constant, the temperature of the radiant panel increases during cooling and decreases during heating compared to a state where the forced convection heat transfer phenomenon does not occur. That is, when the amount of energy input to the heat exchanger is constant, the heat absorption amount and heat release amount (heat transfer amount) by the radiant panel are reduced by performing forced heat exchange (by the fan) as described above. . As a result, the effect of cooling or heating by the original radiation of the radiation type air conditioner is reduced.

上記のように、当該技術分野においては、室内空間における気流速度の増大及び輻射による冷房又は暖房の効果の低減を抑制しつつ室内空間の特定の部位における冷気又は暖気の滞留を効果的に抑制することができる輻射式空調機に対する継続的な要求が存在する。   As described above, in this technical field, the retention of cold air or warm air in a specific part of the indoor space is effectively suppressed while suppressing an increase in airflow velocity in the indoor space and a reduction in the effect of cooling or heating due to radiation. There is a continuing need for radiant air conditioners that can.

本発明は、上記課題に対処することを１つの目的として為されたものである。即ち、本発明は、室内空間における気流速度の増大及び輻射による冷房又は暖房の効果の低減を抑制しつつ室内空間の特定の部位における冷気又は暖気の滞留を効果的に抑制することができる輻射式空調機を提供することを１つの目的とする。   The present invention has been made for one purpose to cope with the above-mentioned problems. That is, the present invention is a radiation type capable of effectively suppressing the stay of cool air or warm air in a specific part of the indoor space while suppressing an increase in the air velocity in the indoor space and a reduction in the effect of cooling or heating due to radiation. One object is to provide an air conditioner.

上記に鑑み、本発明に係る輻射式空調機（以降、「本発明空調機」と称呼される場合がある）は、輻射パネルが水平面と交差する角度にて配置される縦型の輻射式空調機である。具体的には、本発明空調機は、「熱媒体が内部を流通する熱交換部を含んでなる輻射パネル」が水平面と交差する角度にて配置され、前記輻射パネルによる輻射によって冷房及び／又は暖房を行う輻射式空調機である。   In view of the above, the radiant air conditioner according to the present invention (hereinafter sometimes referred to as “the present air conditioner”) is a vertical radiant air conditioner in which the radiant panel is arranged at an angle intersecting the horizontal plane. Machine. Specifically, the air conditioner of the present invention is arranged such that “a radiant panel including a heat exchanging part through which a heat medium flows” is arranged at an angle intersecting a horizontal plane, and is cooled and / or radiated by radiation from the radiant panel. This is a radiant air conditioner for heating.

上記熱媒体は特に限定されず、空調機において広く使用されている種々の熱媒体を使用することができる。典型的には、熱媒体は水である。熱媒体を冷媒として使用する場合（冷房時）、熱媒体は、別途用意される冷却手段によって冷却され、当該冷却手段から熱交換部へと供給される。逆に、熱媒体を熱媒として使用する場合（暖房時）、熱媒体は、別途用意される加熱手段によって加熱され、当該加熱手段から熱交換部へと供給される。   The heat medium is not particularly limited, and various heat media widely used in air conditioners can be used. Typically, the heat medium is water. When the heat medium is used as a refrigerant (during cooling), the heat medium is cooled by a separately prepared cooling unit and supplied from the cooling unit to the heat exchange unit. Conversely, when a heat medium is used as the heat medium (during heating), the heat medium is heated by a separately prepared heating unit and supplied from the heating unit to the heat exchange unit.

また、上記熱交換部は、その内部を流通する熱媒体によって輻射パネルを冷却及び／又は加熱することが可能である限り特に限定されないが、典型的には、高い熱伝導率を有する材料（例えば、金属等）によって形成された伝熱管によって構成される。上記輻射パネルは上記熱交換部を含んでなり、少なくとも一部の面が高い輻射能力（放射能力）を発揮するように構成される。これにより、輻射パネルは、熱交換部によって冷却され、高い輻射能力を有する面による吸熱又は放熱により冷房又は暖房を行う。   The heat exchanging part is not particularly limited as long as the radiant panel can be cooled and / or heated by a heat medium flowing through the inside, but typically, a material having a high thermal conductivity (for example, , Metal, etc.). The radiation panel includes the heat exchange part, and is configured so that at least a part of the surface exhibits high radiation ability (radiation ability). Thereby, a radiation panel is cooled by the heat exchange part, and cools or heats by the heat absorption or heat radiation by the surface which has high radiation capability.

詳しくは後述するように、輻射パネルの外形は特に限定されない。輻射パネルは、例えば、平板状の外形を有し、その内部に熱交換部を熱交換可能な状態で収容していてもよい。この場合、上記「高い輻射能力を有する面」（以降、「輻射面」と称呼される場合がある）は、平板状の外形を有する輻射パネルの一方の面にのみ設けられていても、両方の面に設けられていてもよい。或いは、輻射パネルは、例えば、上記伝熱管が露出した構成を有していてもよく、この場合は、伝熱管の外周面が輻射面となる。   As will be described in detail later, the outer shape of the radiation panel is not particularly limited. The radiant panel may have, for example, a flat outer shape, and the heat exchanging portion may be accommodated in the heat exchanging state. In this case, the “surface having high radiation ability” (hereinafter sometimes referred to as “radiation surface”) may be provided only on one surface of the radiation panel having a flat outer shape. It may be provided on the surface. Or the radiation panel may have the structure which the said heat exchanger tube exposed, for example, In this case, the outer peripheral surface of a heat exchanger tube turns into a radiation surface.

更に、上記輻射パネルは、水平面と交差する角度にて配置される。即ち、本発明空調機は、所謂「縦型」の輻射式空調機である。典型的には、上記輻射パネルは、水平面と直交する角度にて、例えば住居及びオフィス等の建築物の壁面に配置されたり、間仕切りを兼ねる空調機として配置されたりする。そして、本発明空調機は、上記輻射パネルによる輻射によって冷房及び／又は暖房を行うことができる。   Furthermore, the said radiation panel is arrange | positioned at the angle which cross | intersects a horizontal surface. That is, the air conditioner of the present invention is a so-called “vertical” radiation type air conditioner. Typically, the radiation panel is arranged at an angle orthogonal to a horizontal plane, for example, on a wall surface of a building such as a residence and an office, or as an air conditioner that also serves as a partition. And this invention air conditioner can perform air_conditioning | cooling and / or heating by the radiation by the said radiation panel.

加えて、本発明空調機においては、下側吹き出し部及び上側吹き出し部の何れか一方又は両方を更に備える。下側吹き出し部は、前記輻射パネルの下端から前記輻射パネルの構成部材の表面に沿って上向きに流れる空気を上向き補助気流として吹き出す。従って、下側吹き出し部を備える本発明空調機は、前記輻射式空調機による冷房時に、前記輻射パネルの構成部材の表面近傍において冷却されて前記輻射パネルの構成部材の表面に沿って下降する下向き自然対流を、前記上向き補助気流によって、少なくとも部分的に相殺することができる。   In addition, the air conditioner of the present invention further includes either one or both of a lower blowing part and an upper blowing part. The lower blowing section blows out air flowing upward from the lower end of the radiation panel along the surface of the constituent member of the radiation panel as an upward auxiliary airflow. Therefore, the air conditioner according to the present invention including the lower blowout portion is cooled downward in the vicinity of the surface of the component member of the radiation panel and is lowered along the surface of the component member of the radiation panel during cooling by the radiation type air conditioner. Natural convection can be at least partially offset by the upward auxiliary airflow.

上向き補助気流は、下向き自然対流が輻射パネルの構成部材の表面に沿って下降するのを防止又は抑制することを目的として吹き出されるものであり、極めて僅かな気流速度（例えば、０．３ｍ／秒）で十分である。上向き補助気流と下向き自然対流とをバランスさせることにより、輻射パネルの表面付近において冷却された空気が自然対流として下向きに流れて床付近に滞留するのを防止又は抑制することができる。その結果、前述したような強制対流伝熱現象に起因する輻射パネルによる吸熱量（伝熱量）の減少を低減することができる。即ち、下側吹き出し部を備える本発明空調機によれば、室内空間における気流速度の増大及び輻射による冷房の効果の低減を抑制しつつ室内空間の特定の部位における冷気の滞留を効果的に抑制することができる。   The upward auxiliary airflow is blown out for the purpose of preventing or suppressing downward natural convection from descending along the surface of the radiating panel component, and an extremely small airflow velocity (for example, 0.3 m / Seconds) is sufficient. By balancing the upward auxiliary airflow and the downward natural convection, it is possible to prevent or suppress the air cooled in the vicinity of the surface of the radiation panel from flowing downward as natural convection and staying in the vicinity of the floor. As a result, it is possible to reduce the decrease in the amount of heat absorbed (heat transfer amount) by the radiation panel due to the forced convection heat transfer phenomenon as described above. That is, according to the air conditioner of the present invention including the lower blowing portion, it is possible to effectively suppress the stagnation of the cool air in a specific portion of the indoor space while suppressing the increase of the airflow velocity in the indoor space and the reduction of the cooling effect due to radiation. can do.

一方、上側吹き出し部は、前記輻射パネルの上端から前記輻射パネルの構成部材の表面に沿って下向きに流れる空気を下向き補助気流として吹き出す。従って、上側吹き出し部を備える本発明空調機は、前記輻射式空調機による暖房時に、前記輻射パネルの構成部材の表面近傍において加熱されて前記輻射パネルの構成部材の表面に沿って上昇する上向き自然対流を、前記下向き補助気流によって、少なくとも部分的に相殺することができる。   On the other hand, the upper blowing section blows out air flowing downward from the upper end of the radiation panel along the surface of the constituent member of the radiation panel as a downward auxiliary airflow. Therefore, the air conditioner according to the present invention including the upper blowing portion is an upward natural heat which is heated in the vicinity of the surface of the component member of the radiation panel and rises along the surface of the component member of the radiation panel during heating by the radiation type air conditioner. Convection can be at least partially offset by the downward auxiliary airflow.

下向き補助気流は、上向き自然対流が輻射パネルの構成部材の表面に沿って上昇するのを防止又は抑制することを目的として吹き出されるものであり、極めて僅かな気流速度（例えば、０．３ｍ／秒）で十分である。下向き補助気流と上向き自然対流とをバランスさせることにより、輻射パネルの表面付近において加熱された空気が自然対流として上向きに流れて天井付近に滞留するのを防止又は抑制することができる。その結果、前述したような強制対流伝熱現象に起因する輻射パネルによる放熱量（伝熱量）の減少を低減することができる。即ち、上側吹き出し部を備える本発明空調機によれば、室内空間における気流速度の増大及び輻射による暖房の効果の低減を抑制しつつ室内空間の特定の部位における暖気の滞留を効果的に抑制することができる。   The downward auxiliary airflow is blown out for the purpose of preventing or suppressing upward natural convection from rising along the surface of the component of the radiant panel, and an extremely small air velocity (for example, 0.3 m / Seconds) is sufficient. By balancing the downward auxiliary airflow and the upward natural convection, it is possible to prevent or suppress the air heated near the surface of the radiation panel from flowing upward as natural convection and staying near the ceiling. As a result, it is possible to reduce a decrease in the amount of heat released (heat transfer amount) by the radiation panel due to the forced convection heat transfer phenomenon as described above. That is, according to the air conditioner of the present invention provided with the upper blowing portion, it is possible to effectively suppress the stay of warm air in a specific part of the indoor space while suppressing an increase in the airflow velocity in the indoor space and a reduction in the heating effect due to radiation. be able to.

尚、上記説明からも明らかであるように、「自然対流を補助気流によって相殺する」とは、自然対流とは逆向きの補助気流により自然対流の流れを減速又は停止させることを意味する。従って、「自然対流を補助気流によって部分的に相殺する」とは、自然対流とは逆向きの補助気流により自然対流の流れを減速させることを意味し、「自然対流を補助気流によって完全に相殺する」とは、自然対流とは逆向きの補助気流により自然対流の流れを停止させることを意味する。   As is clear from the above description, “cancel natural convection with auxiliary airflow” means that the flow of natural convection is decelerated or stopped by an auxiliary airflow opposite to natural convection. Therefore, “partial cancellation of natural convection by auxiliary airflow” means that the flow of natural convection is decelerated by an auxiliary airflow opposite to natural convection, and “natural convection is completely canceled by auxiliary airflow. “To do” means that the flow of natural convection is stopped by an auxiliary airflow opposite to that of natural convection.

即ち、上向き補助気流及び下向き補助気流として吹き出される空気は、上記のように自然対流を防止又は抑制することを目的とするものであり、自然対流と釣り合った場合は、基本的には、自然対流との接触箇所近傍に留まり、補助気流と輻射パネルとの継続的な熱交換は生じない。従って、補助気流として吹き出される空気は特に加熱又は冷却する必要は無く、例えば、輻射パネルの近傍にある空気を、周囲温度のまま、例えばファン及びブロアー等の送風装置によって上記吹き出し部に供給すればよい。   That is, the air blown out as the upward auxiliary airflow and the downward auxiliary airflow is for the purpose of preventing or suppressing the natural convection as described above. It stays in the vicinity of the contact point with the convection and no continuous heat exchange occurs between the auxiliary airflow and the radiation panel. Therefore, the air blown out as the auxiliary airflow does not need to be heated or cooled. For example, the air in the vicinity of the radiant panel is supplied to the blowing section at the ambient temperature by a blower such as a fan and a blower. That's fine.

また、下側吹き出し部及び上側吹き出し部は、上記のようにして供給された空気を、輻射パネルの構成部材の表面に沿って上向き及び下向きにそれぞれ上向き補助気流及び下向き補助気流として吹き出すことが可能である限り、特に限定されない。典型的には、下側吹き出し部及び上側吹き出し部はそれぞれ上向き補助気流及び下向き補助気流を輻射パネルの構成部材の表面に沿って吹き出すことが可能な形状を有する吹き出し口を備える。そして、上記のようにして供給された空気を上記吹き出し口へと導くための通路及び／又は空間が、その内部に形成されている。   Further, the lower blowing portion and the upper blowing portion can blow out the air supplied as described above as an upward auxiliary airflow and a downward auxiliary airflow respectively upward and downward along the surface of the component member of the radiation panel. As long as it is, it is not particularly limited. Typically, the lower blowing portion and the upper blowing portion each include a blowing port having a shape capable of blowing the upward auxiliary airflow and the downward auxiliary airflow along the surface of the component member of the radiation panel. And the channel | path and / or space for guiding the air supplied as mentioned above to the said blower outlet are formed in the inside.

ところで、上述したように、輻射パネルは、例えば、平板状の外形を有し、その内部に熱交換部が熱交換可能な状態で収容された構成を有していてもよい。また、輻射面は、平板状の外形の一方の面にのみ設けられていても、両方の面に設けられていてもよい。   By the way, as mentioned above, the radiation panel may have a configuration in which, for example, it has a flat outer shape, and the heat exchanging portion is accommodated in the heat exchanging state. Further, the radiation surface may be provided only on one surface of the flat outer shape or may be provided on both surfaces.

即ち、上記実施態様に係る本発明空調機は、
前記輻射パネルが平板状の外形を有し、且つ、前記輻射パネルの両面による輻射によって冷房及び／又は暖房を行い、

Therefore, when performing cooling and / or heating by radiation from both sides of the radiant panel, as described above. The advantages of the present invention can be enjoyed. Such a radiation type air conditioner can be suitably arranged as an air conditioner that also serves as a partition, for example.

或いは、上述したように、輻射パネルは、例えば、伝熱管が露出した構成を有していてもよく、この場合は、伝熱管の外周面が輻射面となる。   Or as above-mentioned, the radiation panel may have the structure which the heat exchanger tube exposed, for example, In this case, the outer peripheral surface of a heat exchanger tube becomes a radiation surface.

即ち、上記実施態様に係る本発明空調機においては、前記輻射パネルが、水平面と交差する角度にて延在して前記熱交換部を構成する少なくとも１本の伝熱管によって構成され、且つ、前記伝熱管の外周面による輻射によって冷房及び／又は暖房を行う。典型的には、上記伝熱管は鉛直方向に延在する。   That is, in the air conditioner of the present invention according to the above-described embodiment, the radiation panel is configured by at least one heat transfer tube that extends at an angle intersecting a horizontal plane and configures the heat exchange unit, and Cooling and / or heating is performed by radiation from the outer peripheral surface of the heat transfer tube. Typically, the heat transfer tube extends in the vertical direction.

上記の場合、前記下側吹き出し部は、前記伝熱管の前記外周面に沿って前記上向き補助気流を吹き出すように構成され、及び／又は、前記上側吹き出し部が前記伝熱管の前記外周面に沿って前記下向き補助気流を吹き出すように構成される。従って、典型的には、各吹き出し部が備える吹き出し口の形状は、伝熱管の（延在方向に垂直な平面による）断面形状に沿った形状となる（例えば、伝熱管の断面が円形であれば、吹き出し口の形状は当該円形と同心のリング状となる）。   In the above case, the lower blowing portion is configured to blow the upward auxiliary airflow along the outer peripheral surface of the heat transfer tube, and / or the upper blowing portion is formed along the outer peripheral surface of the heat transfer tube. The downward auxiliary airflow is blown out. Therefore, typically, the shape of the air outlet provided in each air outlet is a shape along the cross-sectional shape of the heat transfer tube (by a plane perpendicular to the extending direction) (for example, the heat transfer tube has a circular cross section). For example, the shape of the outlet is a ring concentric with the circle).

上記によれば、輻射パネルが平板状の外形を有する場合と比べて、より大きい面積を有する輻射面を確保することができるので、冷房及び／又は暖房の効率を上げることができる。また、輻射パネルが平板状の外形とするための部材（例えば、外装パネル等）を省略することができるので、材料面及び組み立て工数の観点から、製造コストを削減することができる。更に、用途によっては、伝熱管が露出していることが審美的に好ましい場合もある。   According to the above, since a radiation surface having a larger area can be secured as compared with the case where the radiation panel has a flat outer shape, the efficiency of cooling and / or heating can be increased. Moreover, since the member (for example, exterior panel etc.) for making a radiation panel into a flat external shape can be abbreviate | omitted, a manufacturing cost can be reduced from a viewpoint of a material surface and an assembly man-hour. Furthermore, depending on the application, it may be aesthetically preferable that the heat transfer tube is exposed.

ところで、本発明に係る輻射式空調機においては、上述したように生ずる自然対流を補助気流によって少なくとも部分的に相殺するが、自然対流を補助気流によって完全に相殺する方がより好ましい。   By the way, in the radiation type air conditioner according to the present invention, the natural convection generated as described above is at least partially canceled by the auxiliary airflow, but it is more preferable that the natural convection is completely canceled by the auxiliary airflow.

一方、下向き又は上向きの自然対流は、前述したように、それぞれ輻射パネルの表面付近において冷却又は加熱された空気の比重が増大又は減少して周囲の空気の比重との差が生ずるために生ずる。従って、自然対流の気流速度は、輻射パネルの表面付近の空気と周囲の空気との比重差の大きさによって異なる。即ち、自然対流の気流速度は、輻射パネルの表面付近の空気と周囲の空気との温度差の大きさによって異なる。また、輻射面の大きさによっても、自然対流の気流速度は影響される。   On the other hand, the downward or upward natural convection occurs as described above because the specific gravity of the cooled or heated air increases or decreases near the surface of the radiant panel, causing a difference from the specific gravity of the surrounding air. Therefore, the air velocity of natural convection varies depending on the magnitude of the specific gravity difference between the air near the surface of the radiation panel and the surrounding air. That is, the air velocity of natural convection differs depending on the magnitude of the temperature difference between the air near the surface of the radiation panel and the surrounding air. The air velocity of natural convection is also affected by the size of the radiation surface.

従って、自然対流を補助気流によってより完全に相殺するためには、自然対流の気流速度に応じて、補助気流の風量を調節することが可能であることが好ましい。   Therefore, in order to more completely cancel the natural convection with the auxiliary airflow, it is preferable that the airflow of the auxiliary airflow can be adjusted according to the airflow speed of the natural convection.

即ち、上記実施態様に係る本発明空調機は、前記上向き補助気流の風量を調節する上向き風量調節手段、及び／又は、前記下向き補助気流の風量を調節する下向き風量調節手段、を更に備える。これらの風量調節手段は、例えば、補助気流となる空気を吹き出し部に供給するファン及びブロアー等の送風装置に供給される電力を調節することにより、補助気流の風量を調節することができる。この場合、例えば、室内空間に滞在する人間が、自らが感じた自然対流の速度等に応じて、風量調節手段を操作し、補助気流の風量を調節することができる。   That is, the air conditioner of the present invention according to the above embodiment further includes an upward air volume adjusting means for adjusting the air volume of the upward auxiliary airflow and / or a downward airflow adjusting means for adjusting the air volume of the downward auxiliary airflow. These air volume adjusting means can adjust the air volume of the auxiliary airflow, for example, by adjusting the power supplied to the blower or other blower that supplies air serving as the auxiliary airflow to the blowing section. In this case, for example, a person staying in the indoor space can adjust the air volume of the auxiliary air flow by operating the air volume adjusting means according to the natural convection speed felt by the person.

より好ましい実施態様に係る本発明空調機は、自然対流の気流速度に応じて、補助気流の風量を自動的に調節することが可能である。   The air conditioner of the present invention according to a more preferred embodiment can automatically adjust the air volume of the auxiliary airflow according to the airflow speed of natural convection.

即ち、上記実施態様に係る本発明空調機は、少なくとも前記熱媒体の温度に関連する値である媒体温度関連値と前記輻射式空調機が設置された空間の気温に関連する値である気温関連値との差の絶対値が大きいほど前記上向き補助気流及び／又は前記下向き補助気流の風量が大きくなるように前記上向き風量調節手段及び／又は前記下向き風量調節手段を制御する補助気流制御部を更に備える。   That is, the air conditioner of the present invention according to the above embodiment is related to the temperature related to the temperature of the medium, which is a value related to the temperature of the heat medium, and the temperature related to the temperature of the space where the radiant air conditioner is installed. An auxiliary airflow control unit for controlling the upward airflow adjustment means and / or the downward airflow adjustment means so that the airflow of the upward auxiliary airflow and / or the downward auxiliary airflow increases as the absolute value of the difference from the value increases. Prepare.

典型的には、上記媒体温度関連値は、例えば、伝熱管の内部に設けられた温度センサによって検出される熱媒体の温度であり、上記気温関連値は、例えば、輻射式空調機が設置された空間に設けられた温度センサによって検出される当該室内の気温である。尚、媒体温度関連値は、例えば、熱媒体を冷却及び／又は加熱するためのユニット（以降、「冷却／加熱ユニット」と称呼される場合がある）から熱交換部への熱媒体の供給経路に設けられた温度センサによって検出される熱媒体の温度であってもよい。また、気温関連値は、例えば、輻射式空調機を操作するためのリモートコントローラに組み込まれた温度センサによって検出される当該室内の気温であってもよい。   Typically, the medium temperature related value is, for example, the temperature of the heat medium detected by a temperature sensor provided inside the heat transfer tube, and the air temperature related value is, for example, a radiant air conditioner is installed. The temperature of the room detected by a temperature sensor provided in the space. The medium temperature related value is, for example, a heat medium supply path from a unit for cooling and / or heating the heat medium (hereinafter sometimes referred to as “cooling / heating unit”) to the heat exchange unit. It may be the temperature of the heat medium detected by the temperature sensor provided in the. Moreover, the temperature related value may be, for example, the temperature of the room detected by a temperature sensor incorporated in a remote controller for operating the radiation type air conditioner.

例えば、冷房時に媒体温度関連値と気温関連値との差が大きくなるほど、輻射パネルの表面付近の空気の比重と、その周囲の空気の比重との差が大きくなる。具体的には、輻射パネルの表面付近の空気の比重が、その周囲の空気の比重よりもより大きくなる。そのため、輻射パネルの表面付近の空気の下降速度もまた大きくなる（即ち、下向き自然対流の速度が大きくなる）。従って、冷房時の自然対流を上向き補助気流によってより完全に相殺するためには、媒体温度関連値と気温関連値との差が大きくなるほど上向き補助気流の風量が大きくなるように調節することが好ましい。   For example, the greater the difference between the medium temperature related value and the air temperature related value during cooling, the greater the difference between the specific gravity of the air near the surface of the radiation panel and the specific gravity of the surrounding air. Specifically, the specific gravity of the air near the surface of the radiation panel is greater than the specific gravity of the surrounding air. Therefore, the descending speed of the air near the surface of the radiation panel is also increased (that is, the speed of downward natural convection is increased). Therefore, in order to more completely offset the natural convection during cooling by the upward auxiliary airflow, it is preferable to adjust so that the air volume of the upward auxiliary airflow increases as the difference between the medium temperature related value and the temperature related value increases. .

一方、暖房時に媒体温度関連値と気温関連値との差が大きくなるほど、輻射パネルの表面付近の空気の比重と、その周囲の空気の比重との差が大きくなる。具体的には、輻射パネルの表面付近の空気の比重が、その周囲の空気の比重よりもより小さくなる。そのため、輻射パネルの表面付近の空気の上昇速度もまた大きくなる（即ち、上向き自然対流の速度が大きくなる）。従って、暖房時の自然対流を下向き補助気流によってより完全に相殺するためには、媒体温度関連値と気温関連値との差が大きくなるほど下向き補助気流の風量が大きくなるように調節することが好ましい。   On the other hand, the greater the difference between the medium temperature related value and the air temperature related value during heating, the greater the difference between the specific gravity of the air near the surface of the radiation panel and the specific gravity of the surrounding air. Specifically, the specific gravity of the air near the surface of the radiation panel is smaller than the specific gravity of the surrounding air. Therefore, the rising speed of air near the surface of the radiation panel is also increased (that is, the speed of upward natural convection is increased). Therefore, in order to more completely cancel out the natural convection during heating by the downward auxiliary airflow, it is preferable to adjust so that the air volume of the downward auxiliary airflow increases as the difference between the medium temperature related value and the air temperature related value increases. .

尚、上記のような補助気流の風量の制御を行う補助気流制御部は、例えば、ＣＰＵ、ＣＰＵが実行するプログラム及びルックアップテーブル（マップ）等を記憶するＲＯＭ並びにデータを一時的に記憶するＲＡＭ等を含むマイクロコンピュータとして構成することができる。ルックアップテーブルの具体例としては、例えば、「媒体温度関連値と気温関連値との差の大きさ」と「補助気流の風量」との対応関係等を挙げることができる。これにより、補助気流制御部は、検出された媒体温度関連値及び気温関連値に基づき、ルックアップテーブルとして記憶された上記対応関係を参照することにより、自然対流を相殺するのに好適な補助気流の風量を特定することができる。   The auxiliary airflow control unit that controls the airflow of the auxiliary airflow as described above includes, for example, a CPU, a ROM that stores a program executed by the CPU, a lookup table (map), and a RAM that temporarily stores data. Etc. can be configured as a microcomputer. As a specific example of the lookup table, for example, a correspondence relationship between “the magnitude of the difference between the medium temperature related value and the air temperature related value” and “the air volume of the auxiliary airflow” can be cited. Thereby, the auxiliary airflow control unit refers to the correspondence relationship stored as the lookup table based on the detected medium temperature related value and air temperature related value, and is suitable for canceling the natural convection. The air volume can be specified.

以上説明してきたように、本発明に係る輻射式空調機によれば、室内空間における気流速度の増大及び輻射による冷房又は暖房の効果の低減を抑制しつつ室内空間の特定の部位における冷気又は暖気の滞留を効果的に抑制することができる。   As described above, according to the radiant air conditioner according to the present invention, cold air or warm air in a specific part of the indoor space while suppressing an increase in the airflow velocity in the indoor space and a reduction in the effect of cooling or heating due to radiation. Can be effectively suppressed.

＜第１実施形態＞
本発明の第１実施形態に係る輻射式空調機（以下、「第１空調機」と称される場合がある。）につき、添付図面を参照しながら、以下に詳しく説明する。図１は、第１空調機１０の構成を示す模式図である。尚、（ａ）は第１空調機１０の正面図、（ｂ）は第１空調機１０の右側面図、（ｃ）は下側吹き出し部１５の上面に形成された吹き出し口１８を示す上面図である。 <First Embodiment>
The radiation type air conditioner (hereinafter, may be referred to as “first air conditioner”) according to the first embodiment of the present invention will be described in detail below with reference to the accompanying drawings. FIG. 1 is a schematic diagram showing the configuration of the first air conditioner 10. 1A is a front view of the first air conditioner 10, FIG. 2B is a right side view of the first air conditioner 10, and FIG. 2C is an upper surface showing a blowout port 18 formed on the upper surface of the lower blowout portion 15. FIG.

（構成）
第１空調機１０においては、輻射パネル１１が水平面と直交する角度にて配置されている。輻射パネル１１は、熱媒体が内部を流通する複列の伝熱管からなる熱交換部（図示せず）をその内部に含んでなり、輻射パネル１１の表面１２と熱交換するように構成されている。即ち、第１空調機１０は、輻射パネル１１の表面１２による輻射によって冷房及び／又は暖房を行う輻射式空調機である。このような構成を有する輻射パネル１１は、冷房及び／又は暖房を行う空間に表面１２が向かい、当該空間を画定する側壁面に裏面１３が向かうように配置することが望ましい。従って、この例においては、輻射パネル１１の表面１２は高い輻射能力（放射能力）を有することが必須であるが、輻射パネル１１の裏面１３はその限りではない。 (Constitution)
In the 1st air conditioner 10, the radiation panel 11 is arrange | positioned at the angle orthogonal to a horizontal surface. The radiant panel 11 includes a heat exchanging portion (not shown) formed of a double row heat transfer tube through which a heat medium flows, and is configured to exchange heat with the surface 12 of the radiant panel 11. Yes. That is, the first air conditioner 10 is a radiation type air conditioner that performs cooling and / or heating by radiation from the surface 12 of the radiation panel 11. The radiation panel 11 having such a configuration is desirably arranged such that the front surface 12 faces a space for cooling and / or heating, and the back surface 13 faces a side wall surface defining the space. Therefore, in this example, it is essential that the surface 12 of the radiation panel 11 has a high radiation capability (radiation capability), but the back surface 13 of the radiation panel 11 is not limited thereto.

また、この例においては、熱媒体として水を用いたが、前述したように、他の熱媒体を使用することもできる。熱媒体は、図示しない冷却／加熱ユニットにおいて冷却及び／又は加熱され、輻射パネル１１に設けられた供給口及び排出口を通して、輻射パネル１１の内部の熱交換部に循環される。更に、この例においては、複列の伝熱管からなる熱交換部を採用したが、例えば熱交換効率等、必要な性能を達成することが可能である限り、単列の伝熱管からなる熱交換部を採用してもよい。   In this example, water is used as the heat medium. However, as described above, other heat medium can also be used. The heat medium is cooled and / or heated in a cooling / heating unit (not shown), and is circulated to a heat exchange section inside the radiant panel 11 through a supply port and an exhaust port provided in the radiant panel 11. Furthermore, in this example, a heat exchange unit composed of double-row heat transfer tubes is adopted. However, as long as necessary performance such as heat exchange efficiency can be achieved, heat exchange composed of single-row heat transfer tubes, for example. May be adopted.

第１空調機１０は、輻射パネル１１の上端から輻射パネル１１の表面１２に沿って下向きに流れる空気を下向き補助気流１６（下向きの黒塗り矢印）として吹き出す上側吹き出し部１４と、輻射パネル１１の下端から輻射パネル１１の表面１２に沿って上向きに流れる空気を上向き補助気流１７（上向きの黒塗り矢印）として吹き出す下側吹き出し部１５と、を更に備える。上側吹き出し部１４及び下側吹き出し部１５は、補助気流のための空気溜まり及び吹き出し口をそれぞれ有する。尚、この例においては、輻射パネル１１が上側吹き出し部１４及び下側吹き出し部１５の両方を備えるが、例えば、第１空調機１０が暖房専用の空調機である場合は上側吹き出し部１４のみを、逆に第１空調機１０が冷房専用の空調機である場合は下側吹き出し部１５のみを備えるようにしてもよい。   The first air conditioner 10 includes an upper blowing section 14 that blows out air flowing downward from the upper end of the radiation panel 11 along the surface 12 of the radiation panel 11 as a downward auxiliary airflow 16 (a black arrow pointing downward), And a lower blowout portion 15 that blows air that flows upward from the lower end along the surface 12 of the radiation panel 11 as an upward auxiliary airflow 17 (upward black arrow). The upper blowing portion 14 and the lower blowing portion 15 each have an air reservoir and a blowing port for auxiliary airflow. In this example, the radiation panel 11 includes both the upper blowing unit 14 and the lower blowing unit 15. For example, when the first air conditioner 10 is an air conditioner dedicated to heating, only the upper blowing unit 14 is provided. On the other hand, when the first air conditioner 10 is an air conditioner dedicated to cooling, only the lower blowing portion 15 may be provided.

（ｃ）には、下側吹き出し部１５の上面に形成された吹き出し口１８のみを示したが、上側吹き出し部１４の上面に形成された吹き出し口も同様である。更に、（ｃ）において、吹き出し口１８はスリット状の連続的な開口部として構成されているが、吹き出し口１８の形状はこれに限定されず、複数の不連続な開口部の配列として構成されていてもよい。   (C) shows only the air outlet 18 formed on the upper surface of the lower air outlet 15, but the same applies to the air outlet formed on the upper surface of the upper air outlet 14. Furthermore, in (c), the outlet 18 is configured as a slit-like continuous opening, but the shape of the outlet 18 is not limited to this, and is configured as an array of a plurality of discontinuous openings. It may be.

加えて、前述したように、上側吹き出し部１４及び下側吹き出し部１５から補助気流として吹き出される空気は、特に加熱又は冷却する必要は無く、例えば、輻射パネル１１の近傍にある空気を、周囲温度のまま、例えばファン及びブロアー等の送風装置（圧送装置）（図示せず）によって各吹き出し部に供給する。尚、第１空調機１０によって冷房と暖房とを同時に行うことは通常は無いので、上側吹き出し部１４及び下側吹き出し部１５の何れか一方のみから補助気流が吹き出すように、各吹き出し部への空気の供給を例えば切り替え弁等によって制御するようにしてもよい。   In addition, as described above, the air blown out as the auxiliary air flow from the upper blowing portion 14 and the lower blowing portion 15 does not need to be heated or cooled. For example, the air in the vicinity of the radiation panel 11 The temperature is supplied to each blowing unit by a blower (pumping device) (not shown) such as a fan and a blower, for example. Since the first air conditioner 10 does not normally perform cooling and heating at the same time, the auxiliary airflow is blown out from only one of the upper blowing portion 14 and the lower blowing portion 15 to each blowing portion. The supply of air may be controlled by a switching valve or the like, for example.

（作動）
次に、第１空調機１０の作動について説明する。先ず、第１空調機１０による冷房時には、輻射パネル１１の表面１２の近傍の空気が冷却され、その比重が周囲の空気よりも大きくなる。これにより、図４に示すように、輻射パネル１１の表面１２に沿って下降する下向き自然対流（下向きの白抜き矢印）が生じ始める。そこで、下側吹き出し部１５の上面に形成された吹き出し口１８から上向き補助気流１７（上向きの黒塗り矢印）を吹き出すことによって下向き自然対流の下降を止める。これにより、下向き自然対流の継続的な発生を無くし、図６を参照しながら説明したような床付近への冷気の滞留を防止する。 (Operation)
Next, the operation of the first air conditioner 10 will be described. First, during cooling by the first air conditioner 10, the air in the vicinity of the surface 12 of the radiation panel 11 is cooled, and its specific gravity is greater than that of the surrounding air. Thereby, as shown in FIG. 4, downward natural convection (downward white arrow) descending along the surface 12 of the radiation panel 11 starts to occur. Therefore, the downward auxiliary convection is stopped from descending by blowing upward auxiliary airflow 17 (upward black arrow) from the outlet 18 formed on the upper surface of the lower outlet 15. This eliminates the continuous occurrence of downward natural convection and prevents the cold air from staying near the floor as described with reference to FIG.

一方、第１空調機１０による暖房時には、輻射パネル１１の表面１２の近傍の空気が加熱され、その比重が周囲の空気よりも小さくなる。これにより、図５に示すように、輻射パネル１１の表面１２に沿って上昇する上向き自然対流（上向きの白抜き矢印）が生じ始める。そこで、上側吹き出し部１４の上面に形成された吹き出し口から下向き補助気流１６（下向きの黒塗り矢印）吹き出すことによって上向き自然対流の上昇を止める。これにより、上向き自然対流の継続的な発生を無くし、図７を参照しながら説明したような天井付近への暖気の滞留を防止する。   On the other hand, during heating by the first air conditioner 10, the air in the vicinity of the surface 12 of the radiation panel 11 is heated, and its specific gravity is smaller than that of the surrounding air. Thereby, as shown in FIG. 5, upward natural convection (upward white arrow) rising along the surface 12 of the radiation panel 11 starts to occur. Therefore, the upward natural convection is prevented from rising by blowing downward auxiliary airflow 16 (downward black arrow) from the outlet formed on the upper surface of the upper outlet 14. This eliminates the continuous occurrence of upward natural convection and prevents the warm air from staying near the ceiling as described with reference to FIG.

尚、上記説明においては、理解を容易にすることを目的として、補助気流によって自然対流を止め、室内空間の特定の部位における冷気又は暖気の滞留を防止する態様について説明した。しかしながら、補助気流によって自然対流を完全に止めるのではなく、ある程度低減することにより、室内空間の特定の部位における冷気又は暖気の滞留を低減する態様もまた、本発明の範囲に含まれる。   In the above description, for the purpose of facilitating understanding, a mode has been described in which natural convection is stopped by an auxiliary air flow and cold air or warm air is prevented from staying in a specific part of the indoor space. However, an aspect of reducing the stagnation of cold air or warm air in a specific part of the indoor space by reducing the natural convection not completely by the auxiliary air flow but reducing it to some extent is also included in the scope of the present invention.

＜第２実施形態＞
本発明の第２実施形態に係る輻射式空調機（以下、「第２空調機」と称される場合がある。）につき、添付図面を参照しながら、以下に詳しく説明する。図２は、第２空調機２０の構成を示す模式図である。尚、（ａ）は第２空調機２０の正面図、（ｂ）は第２空調機２０の右側面図である。 Second Embodiment
A radiation type air conditioner (hereinafter sometimes referred to as “second air conditioner”) according to a second embodiment of the present invention will be described in detail below with reference to the accompanying drawings. FIG. 2 is a schematic diagram showing the configuration of the second air conditioner 20. In addition, (a) is a front view of the second air conditioner 20, and (b) is a right side view of the second air conditioner 20.

（構成）
（ｂ）からも明らかであるように、第２空調機２０は、輻射パネル２１が平板状の外形を有し、且つ、輻射パネル２１の表面２２及び裏面２３の両方による輻射によって冷房及び／又は暖房を行う輻射式空調機である。このような構成を有する輻射パネル２１は、例えば間仕切り等、表面２２及び裏面２３の両方が冷房及び／又は暖房を行う空間に向かうように配置することができる。従って、この例においては、輻射パネル２１の表面２２及び裏面２３の両方が高い輻射能力（放射能力）を有することが必須である。 (Constitution)
As is clear from (b), in the second air conditioner 20, the radiation panel 21 has a flat outer shape and is cooled and / or radiated by radiation from both the front surface 22 and the back surface 23 of the radiation panel 21. This is a radiant air conditioner for heating. The radiation panel 21 having such a configuration can be arranged so that both the front surface 22 and the back surface 23 are directed to a space for cooling and / or heating, such as a partition. Therefore, in this example, it is essential that both the front surface 22 and the back surface 23 of the radiation panel 21 have high radiation ability (radiation ability).

上記に伴い、第２空調機２０においては、上側吹き出し部２４及び下側吹き出し部２５の両方が輻射パネル２１の表面２２及び裏面２３にそれぞれ設けられている。上側吹き出し部２４は、輻射パネル２１の上端から輻射パネル２１の表面２２及び裏面２３に沿って下向きに流れる空気を下向き補助気流２６（表面側）及び２７（裏面側）（下向きの黒塗り矢印）として吹き出す。一方、下側吹き出し部２５は、輻射パネル２１の下端から輻射パネル２１の表面２２及び裏面２３に沿って上向きに流れる空気を上向き補助気流２８（表面側）及び２９（裏面側）（上向きの黒塗り矢印）として吹き出す。   In connection with the above, in the 2nd air conditioner 20, both the upper side blowing part 24 and the lower side blowing part 25 are provided in the surface 22 and the back surface 23 of the radiation panel 21, respectively. The upper blow-out part 24 has downward auxiliary airflows 26 (front side) and 27 (back side) (downward black arrows) that flow downward from the upper end of the radiation panel 21 along the front surface 22 and the rear surface 23 of the radiation panel 21. Blow out as. On the other hand, the lower blowing section 25 causes upward airflow 28 (front side) and 29 (back side) (upward black) to flow upward from the lower end of the radiation panel 21 along the front surface 22 and the rear surface 23 of the radiation panel 21. Blow out as a filled arrow).

上記を除き、第２空調機２０の構成及び作動は、既に説明した第１空調機１０と実質的に同じである。従って、ここでは第２空調機２０についてのこれ以上の説明は割愛する。   Except for the above, the configuration and operation of the second air conditioner 20 are substantially the same as those of the first air conditioner 10 already described. Therefore, the further description about the 2nd air conditioner 20 is omitted here.

＜第３実施形態＞
