That is, for example, it can be configured as an air layer sheet / aluminum layer / air layer sheet / far-infrared emitting material layer.
　本発明の断熱遮熱シートは、建築物の壁面、天井等の内装材である断熱遮熱クロス（断熱遮熱壁紙）として好適に使用され得る。また、本発明の断熱遮熱シートは、断熱遮熱ロールカーテンもしくはスクリーンとして好適に使用され得る。 The heat insulating and heat insulating sheet of the present invention can be suitably used as a heat insulating and heat insulating cloth (heat insulating and heat insulating wallpaper) that is an interior material such as a wall of a building or a ceiling. Moreover, the heat insulation thermal insulation sheet of this invention can be used suitably as a heat insulation thermal insulation roll curtain or a screen.

　さらに本発明の好適な態様においては、遠赤外線を放射・吸収し遠赤外線の放射率が０．６以上である遠赤外線放射物質を含む材料で構成された室内面構成部材を有し、かつ
　冷暖放射パネル表面が、前記室内面構成部材の前記遠赤外線放射物質と同一の遠赤外線放射物質を含む材料で構成されてなる、放射冷暖房装置において、
　前記室内面構成部材として本発明の断熱遮熱壁紙または断熱遮熱ロールカーテンもしくはスクリーンを用いてなる放射冷暖房装置を提供する。 Furthermore, in a preferred aspect of the present invention, there is provided an indoor surface constituent member made of a material containing a far-infrared emitting material that radiates and absorbs far-infrared rays and has a far-infrared emissivity of 0.6 or more, and is In the radiant cooling and heating apparatus, the surface of the radiating panel is made of a material containing the same far-infrared radiating substance as the far-infrared radiating substance of the indoor surface constituent member,

　ここでは、冷暖放射パネル表面が冷却されると、その表面の前記遠赤外線放射物質が前記室内面構成部材の前記遠赤外線放射物質が放射する遠赤外線を吸収し、または、冷暖放射パネル表面が加熱されると、その加熱面の前記遠赤外線放射物質が放射する遠赤外線を前記室内面構成部材の前記遠赤外線放射物質が吸収するように構成されてなる。 Here, when the surface of the cooling / heating radiation panel is cooled, the far-infrared radiation material on the surface absorbs far-infrared radiation radiated by the far-infrared radiation material of the indoor surface constituent member, or the surface of the cooling / heating radiation panel is heated. Then, the far infrared ray emitted from the far infrared ray emitting material on the heating surface is configured to be absorbed by the far infrared ray emitting material of the indoor surface constituent member.
　本発明において、室内面構成部材とは、環境調整の対象となる密閉空間に露出した面を構成している部材を指す。密閉空間は、その内部と外部との連絡を可能にするドアや窓などのような開閉手段を備えることができる。密閉空間は、特に制限されないが、通常は人間が生活・活動する建物の部屋や廊下などである。室内面構成部材の少なくとも一部は、本発明の断熱遮熱シートを含む断熱遮熱壁紙を用いるので、本発明における室内環境の調整に必要な遠赤外線を放射・吸収する遠赤外線放射物質で構成されるか、遠赤外線放射物質を混入した材料で構成されるか、又は遠赤外線放射物質からなる皮膜を有する。遠赤外線の放射および吸収を効率よく行うため、室内面構成部材中の遠赤外線放射物質は、室内空間に露出していることが好ましい。しかし、室内面構成部材中の遠赤外線放射物質は、室内空間に直接露出されずに、遠赤外線放射物質の遠赤外線の放射・吸収を有意に妨げない程度の保護層（例えば、数ｍｍ以下、好ましくは１ｍｍ程度以下の厚さの塗装膜、ニス層、壁紙等）などで覆われていてもよい。 In the present invention, the term “interior surface constituent member” refers to a member that constitutes a surface exposed to a sealed space that is subject to environmental adjustment. The sealed space can be provided with opening / closing means such as a door or a window that enables communication between the inside and the outside. The sealed space is not particularly limited, but is usually a room or a corridor of a building where people live and act. Since at least a part of the indoor surface constituent member uses the heat insulating and heat insulating wallpaper including the heat insulating and heat insulating sheet of the present invention, it is composed of a far infrared emitting material that emits and absorbs far infrared rays necessary for adjusting the indoor environment in the present invention. Or made of a material mixed with a far-infrared emitting material or having a film made of a far-infrared emitting material. In order to efficiently emit and absorb far-infrared rays, it is preferable that the far-infrared emitting substance in the indoor surface constituting member is exposed to the indoor space. However, the far-infrared emitting material in the indoor surface constituent member is not directly exposed to the indoor space, and the far-infrared emitting material has a protective layer (for example, several mm or less, Preferably, it may be covered with a coating film, varnish layer, wallpaper or the like having a thickness of about 1 mm or less.
　本発明において、遠赤外線放射物質からなる皮膜とは、室内面構成部材や冷却及び／又は加熱源の表面に形成した遠赤外線放射物質の皮膜をいう。この皮膜は、適当な皮膜形成技術、例えば熔射、蒸着などのＰＶＤ技術、あるいはＣＶＤ技術により、遠赤外線放射物質を対象表面にコーティングして形成することができる。 In the present invention, a film made of a far-infrared emitting material means a film of a far-infrared emitting material formed on the surface of an indoor surface constituent member or a cooling and / or heating source. This film can be formed by coating the target surface with a far-infrared radiation material by an appropriate film forming technique, for example, PVD technique such as spraying or vapor deposition, or CVD technique.
　本発明においては、室内面構成部材の遠赤外線放射物質と、冷暖放射パネル表面の遠赤外線放射物質とは、同一である。本発明における放射冷暖房装置は、同一分子種間における熱放射を介した熱移動が、同一分子種間でない場合に比較して高い効率で行われる現象を利用して、室内面構成部材と冷暖放射パネル表面との間で熱放射を介し熱移動を高い効率で行わせることにより、室内環境の調整を実現するものである。よって、本発明の放射冷暖房装置が所期の機能を発揮するためには、それらの間で熱放射を介した熱移動が行われる室内面構成部材と冷暖放射パネル表面とに、同一分子種の物質が存在する必要がある。本発明では、同一分子種で構成されている、室内面構成部材の遠赤外線放射物質と冷却および／または加熱源の遠赤外線放射物質のことを、同一物質であると称する。ここで「同一分子種」とは、遠赤外線を放射・吸収する性質を示し、遠赤外線の放射率が０．６以上、好ましくは０．８以上である一方の物質（例えば、室内面構成部材において使用する遠赤外線放射物質）と、遠赤外線を放射・吸収する性質を示し、遠赤外線の放射率が０．６以上、好ましくは０．８以上であるもう一方の物質（冷暖放射パネル表面で使用する遠赤外線放射物質）とが、分子レベルで同一であることをいう。ここでの分子とは、化学結合により結合された原子の集団を意味する。したがって、ここでいう分子には、例えば天然石材を構成する鉱物の結晶なども含まれる。類似元素が置換あるいは固溶した同一鉱物は同一分子種の物質とみなされている。天然の鉱物の場合、複数の化合物で構成されるのが普通であり、しかも巨視的レベルでは鉱物中の部位によりそれらの化合物の結晶構造に違いが見られることもある。とは言え、この場合は、同じ原産地から切り出した鉱物は、実質的に同じ分子種の物質の実質的に同じ組成の集合体であり、全体として同一分子種の物質と同様に考えてよい。 In the present invention, the far-infrared emitting material of the indoor surface constituent member and the far-infrared emitting material on the surface of the cooling / heating radiation panel are the same. The radiant cooling and heating apparatus according to the present invention uses a phenomenon in which heat transfer via thermal radiation between the same molecular species is performed with higher efficiency than in the case where the same molecular species is not between the same molecular species. Adjustment of the indoor environment is achieved by causing heat transfer to and from the panel surface through heat radiation with high efficiency. Therefore, in order for the radiant cooling / heating device of the present invention to perform its intended function, the indoor surface constituent member and the cooling / heating radiant panel surface where heat transfer is performed between them are used for the same molecular species. The substance needs to be present. In the present invention, the far-infrared emitting material of the indoor surface constituent member and the far-infrared emitting material of the cooling and / or heating source, which are composed of the same molecular species, are referred to as the same material. Here, the “same molecular species” indicates a property of radiating and absorbing far infrared rays, and one substance (for example, an indoor surface constituent member) having far infrared emissivity of 0.6 or more, preferably 0.8 or more. Far-infrared emitting material used in) and the other infrared ray emitting / absorbing material that has a far-infrared emissivity of 0.6 or more, preferably 0.8 or more. This means that the far-infrared emitting material used is the same at the molecular level. The molecule here means a group of atoms bonded by chemical bonds. Therefore, the molecule referred to here includes, for example, a crystal of a mineral constituting a natural stone material. The same mineral with substitution or solid solution of similar elements is regarded as a substance of the same molecular species. In the case of a natural mineral, it is usually composed of a plurality of compounds, and on the macroscopic level, the crystal structure of these compounds may be different depending on the site in the mineral. However, in this case, the mineral cut out from the same place of origin is a collection of substantially the same composition of substances of substantially the same molecular species, and may be considered in the same way as a substance of the same molecular species as a whole.
　室内面構成部材、あるいは冷暖放射パネル表面において、上述の遠赤外線放射物質として無機材料粒子を使用する場合、そこには、遠赤外線放射物質としての無機材料粒子以外の物質が共存するのが普通である。例えば、遠赤外線放射物質としての無機材料粒子を含む漆喰により室内面構成部材を形成した場合や、遠赤外線放射物質としての無機材料粒子を含む塗料を冷暖放射パネル表面に塗布した場合、上述の遠赤外線放射物質としての無機材料粒子は、漆喰中の骨材あるいは塗料中のバインダー成分などと共存する。このような場合、上述の「遠赤外線放射物質」としての無機材料粒子以外の物質も、遠赤外線を多かれ少なかれ放射・吸収する性質を持つ。しかし、本発明では、同一分子種間における熱放射を介した熱移動が同一分子種間でない場合に比較して顕著に高い効率で行われる現象を利用しているので、室内面構成部材と冷暖放射パネル表面の両者に共通に存在しない物質が本発明において果たす役割は、きわめて少ないか、または無視できる程度である。したがって、以下における本発明の説明において「遠赤外線放射物質」に言及する場合、それは室内面構成部材と冷暖放射パネル表面の両者に共通に存在する、遠赤外線放射率０．６以上、好ましくは０．８以上の同一の物質（電磁波を介した同一分子間における分子振動の共鳴現象を引き起こす物質）を指す。 When inorganic material particles are used as the above-mentioned far-infrared radiation material on the interior surface component or the cooling / heating radiation panel surface, it is normal that substances other than inorganic material particles as the far-infrared radiation material coexist there. is there. For example, when the indoor surface constituent member is formed of plaster containing inorganic material particles as a far-infrared emitting material, or when a paint containing inorganic material particles as a far-infrared emitting material is applied to the surface of a cooling / heating radiation panel, The inorganic material particles as the infrared emitting substance coexist with the aggregate in the plaster or the binder component in the paint. In such a case, substances other than the inorganic material particles as the “far-infrared emitting substance” described above also have the property of emitting or absorbing far-infrared rays more or less. However, the present invention uses a phenomenon in which heat transfer via thermal radiation between the same molecular species is performed with significantly higher efficiency than when the same molecular species is not between the same molecular species. Substances that are not commonly present on both sides of the radiating panel play a very small or negligible role in the present invention. Therefore, when referring to “far-infrared emitting material” in the following description of the present invention, it is common to both the interior surface component and the surface of the cooling / heating panel, and far-infrared emissivity is 0.6 or more, preferably 0. .8 or more identical substances (substances that cause resonance phenomenon of molecular vibrations between identical molecules via electromagnetic waves).
　室内面構成部材と冷暖放射パネル表面とで遠赤外線放射物質としてともに無機材料粒子を使用する場合には、双方の粒子の粒径や形状は同一でも異なっていてもよい。室内面構成部材と冷暖放射パネル表面の双方に含まれる無機材料粒子の配合量も、同じである必要はない。また、例えば、室内面構成部材が壁面と天井面を形成していて、遠赤外線放射物質として無機材料粒子を使用する場合、壁面と天井面の遠赤外線放射物質の粒子の粒径や形状は、同一でも異なっていてもよい。この場合、無機材料粒子は、室内面構成部材（たとえば、壁面及び天井面を形成する建材）中に、本発明による同一分子種間での熱放射を介した所期の熱移動を可能にする含有量で配合される。このとき、壁面を形成する建材と天井面を形成する建材とで、無機材料粒子の配合量は同一でも異なっていてもよい。これらは、２以上の壁面のそれぞれにおける遠赤外線放射物質の無機材料粒子についてもいえる。 When the inorganic material particles are used as the far-infrared radiation material on the indoor surface constituent member and the cooling / heating radiation panel surface, the particle size and shape of both particles may be the same or different. The blending amount of the inorganic material particles contained in both the indoor surface component and the cooling / heating radiation panel surface need not be the same. Further, for example, when the indoor surface constituent member forms a wall surface and a ceiling surface, and the inorganic material particles are used as the far infrared radiation material, the particle size and shape of the far infrared radiation material particles on the wall surface and the ceiling surface are: It may be the same or different. In this case, the inorganic material particles enable the desired heat transfer through thermal radiation between the same molecular species according to the present invention in the interior surface constituent members (for example, building materials forming the wall surface and the ceiling surface). It is blended by content. At this time, the amount of the inorganic material particles may be the same or different between the building material forming the wall surface and the building material forming the ceiling surface. These also apply to the inorganic material particles of the far-infrared emitting material on each of the two or more wall surfaces.
　室内面構成部材と冷暖放射パネル表面において、遠赤外線放射物質は複数種を用いてもよい。遠赤外線放射物質が石材の場合は、室内面構成部材あるいは冷暖放射パネル表面のために、２種以上の石材を組み合わせて用いることができる。遠赤外線放射物質が無機材料粒子の場合は、２種以上の無機材料粒子の混合物を用いることができる。どちらの場合も、室内面構成部材における無機材料粒子の組み合わせと冷暖放射パネル表面における無機材料粒子の組み合わせが同じであれば（同じ組み合わせが含まれていれば）、それらは「同一物質」であると見なされる。 Multiple types of far-infrared emitting materials may be used on the interior surface components and the surface of the cooling / heating radiation panel. When the far-infrared radiation material is a stone material, two or more kinds of stone materials can be used in combination for the indoor surface constituent member or the cooling / heating radiation panel surface. When the far-infrared emitting material is inorganic material particles, a mixture of two or more inorganic material particles can be used. In both cases, if the combination of the inorganic material particles in the interior surface component and the combination of the inorganic material particles on the surface of the cooling / heating radiation panel are the same (if the same combination is included), they are “the same substance”. Is considered.
　室内面構成部材と冷暖放射パネル表面に含まれる遠赤外線放射物質としての無機材料粒子は、同一分子種間での熱放射を介した所期の熱移動を可能にする量でそれらに存在する。通常、室内面構成部材と冷暖放射パネル表面は、異なる業者により、建設現場以外で製作して建設現場に搬入されるか又は建設現場において施工されることが多いと考えられる。従って、室内面構成部材と冷暖放射パネル表面には、遠赤外線放射物質としての共通の無機材料粒子が、それぞれの製造業者又は施工業者により混入されることが多いと考えられる。このような場合、遠赤外線放射物質としての無機材料粒子の含有量は、それぞれの業者により室内面構成部材と冷暖放射パネル表面の各製造材料に含められる共通の無機材料粒子の量をいう。室内面構成部材中及び冷暖放射パネル表面形成材料中の無機材料粒子含有量は、本発明による熱放射を介した熱移動を実効あるものにする量として決定することができる。その量は、所期の冷房および／または加熱のために必要とされる熱移動量、熱放射を介した熱移動に利用可能な室内面構成部材と冷却および／または加熱面の面積、使用する遠赤外線放射物質の熱放射特性などに依存する。下記で説明する計測実験では、遠赤外線放射物質としての無機材料粒子は、室内面構成部材材料中、あるいは冷暖放射パネル表面を形成している材料中に、１重量％以上存在する場合に有効な効果が認められ、３重量％以上存在する場合により好ましい効果が得られた。一方、遠赤外線放射物質として無機材料粒子を用いる場合、その含有量の上限は、室内面構成部材と冷暖放射パネル表面を形成する材料中に実際上含ませることができる無機材料粒子の最大量によって決まり、特に制約はない（理論的には、例えば９０重量％でもよい）。 The inorganic material particles as far-infrared radiation materials contained in the indoor surface constituent members and the surface of the cooling / heating radiation panel are present in them in an amount that enables the desired heat transfer via thermal radiation between the same molecular species. In general, it is considered that the indoor surface component and the cooling / heating radiation panel surface are often manufactured by a different contractor outside the construction site and carried into the construction site or installed at the construction site. Therefore, it is considered that common inorganic material particles as far-infrared radiation materials are often mixed into the indoor surface constituent member and the cooling / heating radiation panel surface by respective manufacturers or contractors. In such a case, the content of the inorganic material particles as the far-infrared emitting material refers to the amount of the common inorganic material particles included in the respective manufacturing materials of the indoor surface constituent member and the cooling / heating radiation panel surface by each supplier. The content of inorganic material particles in the interior surface constituting member and in the cooling / heating radiation panel surface forming material can be determined as an amount that makes the heat transfer through heat radiation effective according to the present invention. The amount used is the amount of heat transfer required for the desired cooling and / or heating, the room surface components available for heat transfer via heat radiation and the area of the cooling and / or heating surface Depends on the thermal radiation characteristics of far-infrared radiation materials. In the measurement experiment described below, the inorganic material particles as the far-infrared radiation material are effective when they are present in the interior surface component material or the material forming the cooling / heating radiation panel surface in an amount of 1% by weight or more. An effect was recognized, and a more preferable effect was obtained when the content was 3% by weight or more. On the other hand, when inorganic material particles are used as the far-infrared emitting material, the upper limit of the content depends on the maximum amount of inorganic material particles that can actually be included in the material forming the indoor surface constituent member and the cooling / heating radiation panel surface. There are no particular restrictions (theoretically, for example, it may be 90% by weight).
　本発明では、遠赤外線放射物質の無機材料粒子として、複数種の物質を使用（上述の「分子レベルで同一」である物質を複数種使用）してもよい。この場合には、室内面構成部材と冷暖放射パネル表面とで同じ無機材料粒子の混合物を用いることができる。この場合の室内面構成部材材料と冷暖放射パネル表面を形成している材料における無機材料粒子の含有量は、混合物中の複数種の同じ物質の合計量でもって表される。 In the present invention, plural types of substances may be used as the inorganic material particles of the far-infrared emitting substance (multiple types of substances that are “identical at the molecular level” described above are used). In this case, the same mixture of inorganic material particles can be used for the interior surface constituting member and the cooling / heating radiation panel surface. In this case, the content of the inorganic material particles in the material forming the indoor surface constituent member material and the surface of the cooling / heating radiation panel is expressed by the total amount of the same kind of substances in the mixture.
　遠赤外線の放射および吸収を効率よく行うためには、遠赤外線放射物質は極力、環境調整する室内空間に露出していることが好ましい。とは言え、遠赤外線放射物質が室内空間に直接露出していなくても、１ｍｍ程度以下の保護層（例えば塗装の層、ニスの層、壁紙等）で覆われているのであれば、大きな問題はない。 In order to efficiently radiate and absorb far-infrared rays, it is preferable that far-infrared emitting materials are exposed to the indoor space where the environment is adjusted as much as possible. However, if the far-infrared emitting material is not directly exposed to the indoor space, it is a major problem if it is covered with a protective layer of about 1 mm or less (for example, a paint layer, a varnish layer, wallpaper, etc.). There is no.
　本発明で使用する遠赤外線放射物質の遠赤外線の放射率は、０．６以上であり、好ましくは０．８以上、より好ましくは０．９以上である。遠赤外線は、波長が３μｍ～１０００μｍの電磁波のことをいう。材料の放射率は、同一条件における理想的な黒体の遠赤外線の放射エネルギーをＷ0とし、当該材料の遠赤外線の放射エネルギーをＷとした場合に、Ｗ／Ｗ0によって定義される。放射率の値は、本発明のシステムの実際の使用温度に近い室温（例えば２５℃）におけるものが好ましく、例えば、人体に対する熱的な作用の大きい１０μｍ付近における値を採用する。 The far-infrared emissivity of the far-infrared emitting material used in the present invention is 0.6 or more, preferably 0.8 or more, more preferably 0.9 or more. Far-infrared radiation refers to electromagnetic waves having a wavelength of 3 μm to 1000 μm. The emissivity of a material is defined by W / W 0 where W 0 is the ideal black body far-infrared radiation energy under the same conditions and W is the far-infrared radiation energy of the material. The emissivity value is preferably at room temperature (for example, 25 ° C.) close to the actual use temperature of the system of the present invention.
　本発明の一態様において、冷暖放射パネルのフィンの表面は、遠赤外線放射物質の粉砕物とバインダーとを混合し、それを層状に塗り、乾燥させることでコーティングされている。たとえば、フィンの表面には、遠赤外線の放射率が０．９を超える数値を示す花崗岩を粉砕した粉砕物（以下、石粉という）を混ぜた白い塗料により構成された厚さ約２００μｍのコーティング層が形成される。コーティング層中の石粉の粒径は、５０μｍ以下である。この石粉のコーティング層における含有率は、塗料の硬化状態（乾燥状態）で２０重量％とされている。ここでは、冷却および／または加熱面を有する冷暖放射パネルは、遠赤外線放射物質をコーティングされたフィンを有するラジエーターで構成されており、冷房運転時にラジエーター表面に空気中の水分が結露して生成した水滴を屋外に排出するために、ラジエーター下方の水滴受部の排水口から屋外の排水出口に至る排水系を設けている。 In one aspect of the present invention, the surfaces of the fins of the cooling / heating panel are coated by mixing a pulverized far-infrared emitting material and a binder, coating them in layers, and drying. For example, on the surface of the fin, a coating layer having a thickness of about 200 μm composed of a white paint mixed with a pulverized granite (hereinafter referred to as stone powder) whose far-infrared emissivity exceeds 0.9 is obtained. Is formed. The particle size of the stone powder in the coating layer is 50 μm or less. The content of the stone powder in the coating layer is 20% by weight in the cured state (dry state) of the paint. Here, the cooling and heating radiant panel having a cooling and / or heating surface is composed of a radiator having fins coated with a far-infrared radiation material, and moisture in the air is generated on the radiator surface during the cooling operation. In order to discharge water drops outdoors, a drainage system is provided from the drain outlet of the water drop receiver below the radiator to the outdoor drain outlet.
　ラジエーターは、たとえば表面をコーティング加工したアルミニウム製のフィンを複数備えている。このフィンは、薄手の板状であり、上下に延在している。フィンは、熱伝導の良好な他の金属または合金材料、例えば鉄や銅、それらの合金など、で製作することもできる。このフィンの表面は、遠赤外線放射物質の粉砕物とバインダーとを混合し、それを層状に塗り、乾燥させることでコーティングされている。 The radiator includes a plurality of aluminum fins whose surfaces are coated, for example. This fin is a thin plate-like shape and extends vertically. The fins can also be made of other metal or alloy materials with good thermal conductivity, such as iron, copper, and alloys thereof. The surface of the fin is coated by mixing a pulverized product of a far-infrared emitting material and a binder, coating it in layers, and drying it.
　フィンは、アルミニウム製の支持板と一体形成されている。支持板の裏面側は、冷媒通路に露出している。冷媒通路には、冷媒として冷水が循環する。この冷媒は、冷却源である冷媒冷却装置により冷却される。冷媒冷却装置の冷却機構は、一般的な空調装置や冷蔵庫に利用されているものと同じである。 The fins are integrally formed with an aluminum support plate. The back side of the support plate is exposed to the refrigerant passage. In the refrigerant passage, cold water circulates as a refrigerant. This refrigerant is cooled by a refrigerant cooling device that is a cooling source. The cooling mechanism of the refrigerant cooling device is the same as that used in general air conditioners and refrigerators.
　冷却面の下方には、排水口が設けられている。冷媒通路内を冷却水が循環すると、フィンが冷却され、フィンの表面の遠赤外線物質層も冷却され、に含まれた床面、壁面、天井面の室内面構成部材から放射された遠赤外線を吸収して、部屋内の環境の冷却が行われる。また、冷却面の表面に室内空間の空気中に含まれる水分が結露する。この結露した水滴は、排水口に滴下し、排水口から排水出口へ移動し、室外に排出される。 A drain outlet is provided below the cooling surface. When the cooling water circulates in the refrigerant passage, the fins are cooled, the far-infrared material layer on the surface of the fins is also cooled, and far-infrared rays radiated from the indoor surface constituent members included in the floor surface, wall surface, and ceiling surface are contained. Absorbs and cools the environment in the room. Further, moisture contained in the air in the indoor space is condensed on the surface of the cooling surface. The condensed water droplets are dropped onto the drain outlet, move from the drain outlet to the drain outlet, and are discharged outside the room.
　冷却および／または加熱源のために、冷熱放射装置が好適に使用され、冷放射と熱放射を切り換えて行うことができる。冷放射は、冷却されることで、周囲からの熱放射を吸収する作用のことをいい、熱放射は、加熱されることで、周囲に向かって熱放射を行う作用のことをいう。 For the cooling and / or heating source, a cold heat radiation device is preferably used, and it is possible to switch between the cold radiation and the heat radiation. Cold radiation refers to the action of absorbing heat radiation from the surroundings when cooled, and heat radiation refers to the action of performing heat radiation toward the surroundings when heated.
　このような冷熱放射装置は、室外機である冷温水発生装置に接続されている。冷温水発生装置は、ヒートポンプ機能を備え、冷水または温水を発生する。このヒートポンプ機能は、通常のエアコン等に用いられているものと同じ原理により動作する。なお、冷房効果だけを得るのであれば、冷水の発生機能だけでよい。また、暖房効果だけを得るのであれば、温水の発生機能だけでよい。 Such a cold heat radiation device is connected to a cold / hot water generator which is an outdoor unit. The cold / hot water generator has a heat pump function and generates cold water or hot water. This heat pump function operates according to the same principle as that used in ordinary air conditioners and the like. If only the cooling effect is obtained, only the function of generating cold water is required. Moreover, if only the heating effect is obtained, only the function of generating hot water is required.
　冷熱放射装置に、冷温水発生装置から冷水が供給されると、フィンが冷やされ、結露による除湿が行われる。また冷却されることで、フィンの表面は、冷放射を行う冷却面として機能する。また、冷熱放射装置に、冷温水発生装置から温水が供給されると、上記フィンが温められ、このフィンの表面が加熱面（熱放射面）として機能する。なお、冷水というのは、冷温水発生装置の冷却機能によって冷却された水のことであり、温水というのは、冷温水発生装置の加熱機能によって加熱された水のことをいう。なお、上記のように、フィンに結露した水滴は、下方のトレイに滴下させて集められ、排水口から屋外に排水される。 When cold water is supplied from the cold / hot water generator to the cold heat radiation device, the fins are cooled and dehumidification is performed by condensation. Moreover, the surface of a fin functions as a cooling surface which performs cold radiation by being cooled. Further, when hot water is supplied from the cold / hot water generator to the cold heat radiating device, the fin is warmed, and the surface of the fin functions as a heating surface (heat radiating surface). Note that the cold water is water cooled by the cooling function of the cold / hot water generator, and the hot water is water heated by the heating function of the cold / hot water generator. As described above, the water droplets condensed on the fins are collected by being dropped onto the lower tray and drained to the outside from the drain outlet.
　本発明の一態様において、フィンの表面には、遠赤外線の放射率が０．９を超える数値を示す花崗岩を粉砕した粉砕物（以下、石粉という）を混ぜた白い塗料により構成された厚さ約２００μｍのコーティング層が形成される。コーティング層中の石粉の粒径は、５０μｍ以下である。この石粉のコーティング層における含有率は、塗料の硬化状態（乾燥状態）で２０重量％とされている。このコーティング層が冷却除湿面および加熱面として機能する。 In one embodiment of the present invention, the surface of the fin has a thickness composed of a white paint mixed with a pulverized product (hereinafter referred to as stone powder) obtained by pulverizing granite showing a numerical value of emissivity of far infrared rays exceeding 0.9. A coating layer of about 200 μm is formed. The particle size of the stone powder in the coating layer is 50 μm or less. The content of the stone powder in the coating layer is 20% by weight in the cured state (dry state) of the paint. This coating layer functions as a cooling and dehumidifying surface and a heating surface.
