従来の縦型のエアコンは上記文献にあるように室内機と室外機を前後に分割してある。
【０００３】
【発明が解決しようとする課題】
そのため、大きな設置面積が必要で設置場所が限定される問題がある。そこで、これらの問題点を解決すると共に床輻射空調ができるスリム形エアコンを提供することを目的とする。
【０００４】
【課題を解決するための手段】
上記目的を達成するために、本発明のスリム形エアコンは、排気口と給気口と還気取入口と外気取入口を有する細長箱状のケーシング内に、凝縮器と排気ファンを設けた排気送風路と、蒸発器と再熱器と給気ファンを設けた給気送風路と、前記給気送風路と前記排気送風路の間に設けられて外気をこの給気送風路とこの排気送風路へ分流させると共に還気をこの給気送風路とこの排気送風路へ分流させる分流チャンバと、を備え、前記排気口に連通する前記排気送風路と、前記還気取入口と前記外気取入口に連通する前記分流チャンバと、前記給気口に連通する前記給気送風路と、を直列に配置し、前記分流チャンバを、前記ケーシングに対して取出・収納自在に構成した。さらに、分流チャンバが、給気用還気ダンパと排気用還気ダンパと給気用外気ダンパと排気用外気ダンパと、還気取入口から取入れた還気を前記給気用還気ダンパから給気送風路へ導く給気用還気路と、前記還気取入口から取入れた還気を前記排気用還気ダンパから排気送風路へ導く排気用還気路と、外気取入口から取入れた外気を前記給気用外気ダンパから前記給気送風路へを導く給気用外気路と、前記外気取入口から取入れた外気を前記排気用外気ダンパから前記排気送風路へ導く排気用外気路と、を備えると共に、前記分流チャンバ内を仕切って分割し、この仕切面の一の対角線に沿ってその一方の分割部内を仕切って前記給気用還気路と前記排気用外気路を形成し、前記仕切面の前記対角線と交差する他の対角線に沿って他方の分割部内を仕切って前記排気用還気路と前記給気用外気路を形成した。給気口をケーシングの下端部に設けて床輻射空調用の床下内に連通させると共に、その床又は室内の床近傍部に、前記給気口からの給気を前記室内に吹出すための吹出口を、設けた。さらに、蒸発器と凝縮器と再熱器の各々のフィンチューブを楕円管にした。
【０００５】
【発明の実施の形態】
図１〜図３は、本発明のスリム形エアコンの一実施例を示しており、このエアコンは、排気口３と給気口５と還気取入口２と外気取入口４を有する細長箱状のケーシング１内に、冷媒循環回路１３と、凝縮器９と排気ファン１０を設けた排気送風路Ｂと、蒸発器６と再熱器７と給気ファン８を設けた給気送風路Ａと、給気送風路Ａと排気送風路Ｂの間に設けられて外気をこの給気送風路Ａとこの排気送風路Ｂへ分流させると共に還気をこの給気送風路Ａとこの排気送風路Ｂへ分流させる分流チャンバ１１と、を備えている。排気口３に連通する排気送風路Ｂと、還気取入口２と外気取入口４に連通する分流チャンバ１１と、給気口５に連通する給気送風路Ａと、は直列に配置する。実線及び点線の白抜き矢印は風向を示す。
【０００６】
分流チャンバ１１は、給気用還気ダンパ１５と排気用還気ダンパ１６と給気用外気ダンパ１７と排気用外気ダンパ１８と、還気取入口２から取入れた還気を給気用還気ダンパ１５から給気送風路Ａへ導く給気用還気路１９と、還気取入口２から取入れた還気を排気用還気ダンパ１６から排気送風路Ｂへ導く排気用還気路２０と、外気取入口４から取入れた外気を給気用外気ダンパ１７から給気送風路Ａへを導く給気用外気路２１と、外気取入口４から取入れた外気を排気用外気ダンパ１８から排気送風路Ｂへ導く排気用外気路２２と、を備えると共に、分流チャンバ１１内を仕切って分割し、この仕切面の一の対角線に沿ってその一方の分割部内を仕切って給気用還気路１９と排気用外気路２２を形成し、前記仕切面の前記対角線と交差する他の対角線に沿って他方の分割部内を仕切って排気用還気路２０と給気用外気路２１を形成する。還気ダンパ１５、１６は還気路１９、２０の空気入口に設け、外気ダンパ１７、１８は外気路２１、２２の空気入口に設ける。この分流チャンバ１１は仕切部材やダンパ１５、１６、１７、１８等と共に一体に設けて、ケーシング１に対して取出・収納自在に構成する。
【０００７】
給気口５はケーシング１の下端部に設けて床輻射空調用の床下内に連通させると共に、その床２３又は室内の床近傍部に、給気口５からの給気を室内に吹出すための吹出口１２を、設ける。床２３の下面には、蓄熱材２５を介して、給気が接触する多数の棒状の伝熱体２４…を互いに間をあけて垂下させ、かつ伝熱体２４…の下端部と床底との間をあけて圧損防止と乱流効果を得る。床底のスラブ部分には断熱材２６を設けて蓄熱効果を高め、この床下内に給気を行って伝熱体２４…と蓄熱材２５に接触させ、床２３に給気熱を伝えて輻射空調しつつ、吹出口１２から還気取入口２へ給気を循環させて室内を空調する。このように給気を輻射熱源としているので別個に電気ヒーターや冷温水パイプなどの機器や熱源が不要でランニングコスト及び設備コストを削減できる。伝熱体２４を介して給気と床部分を効率良く熱交換して床輻射空調でき、しかも伝熱体２４は棒状で間をあけてあるので圧損が少なくてすむ。また伝熱体２４と床２３の間に蓄熱材２５を介せば、床全域に均等に伝熱し、むらなく床輻射空調が行え、輻射熱量や輻射時間の調整が可能となる。なお、蓄熱材２５を省略して床２３の下面に直接、伝熱体２４を垂下させてもよい。また、蓄熱材２５と伝熱体２４…と断熱材２６を省略するも自由である（図４参照）。図例ではケーシング１の先端部（上端部）に排気口３を、基端部（下端部）に給気口５を、それぞれ形成し、ケーシング１の胴部の適宜面（例えば対向面）に外気取入口４と還気取入口２を形成しているが、図１、図４、図５のように、それらの位置変更は自由である。排気口３と外気取入口４はダクトやがらり等を介して屋外に通じさせる。
【０００８】
冷媒循環回路１３は、蒸発器６、凝縮器９、再熱器７、圧縮機１４、図示省略の受液器、膨張弁及び冷媒循環方向の正逆の切換弁等を配管接続して成り、蒸発器６及び凝縮器９の吸熱と放熱を切換自在に構成する。再熱器７は蒸発器６の風下に設け、凝縮器９に流れる冷媒（ホットガス）の一部を再熱器７にバイパスさせて過冷却・除湿・再熱自在に構成する。蒸発器６と凝縮器９と再熱器７の各々のフィンチューブは楕円管にするのが好ましいが円形管でもよい。
【０００９】
蒸発器６及び再熱器７の風下には吸込式の給気ファン８を設けるとともに凝縮器９の風下に吸込式の排気ファン１０を設け、凝縮器９の風上に圧縮機１４や受液器などの冷媒循環回路１３の部品を設ける。排気ファン１０、凝縮器９、圧縮機１４、蒸発器６、再熱器７、給気ファン８は直線状に配置して細長状のケーシング１内に収めてコンパクト化を図る。なお、蒸発器６、再熱器７、給気ファン８、凝縮器９、排気ファン１０、圧縮機１４などの配置は図例以外のものとするも自由である。また、図示省略するが加湿器を再熱器７の風下に設けるも自由である。冷媒循環回路１３は、図示省略のフレームなどに一体に設けて、ケーシング１に対して取出・収納自在に構成するも自由であり、ケーシング全体を取り外すことなく冷媒循環回路１３のみをケーシング１から取出して冷媒回収作業やメンテナンスを容易に行え、取付け収納にも手間がかからない。また、冷媒循環回路１３だけ交換することにより、リニューアル時のコストダウンも図れる。
【００１０】
給気用還気ダンパ１５と排気用還気ダンパ１６と給気用外気ダンパ１７と排気用外気ダンパ１８は各種の運転制御装置等により風量制御を行う。各ダンパ１５、１６、１７、１８は、全閉・全開切換のみ又は任意風量可変自在の何れの構造であってもよいが、例えば、給気用還気ダンパ１５と排気用外気ダンパ１８を連動開閉するように構成し、排気用還気ダンパ１６と給気用外気ダンパ１７を連動開閉するように構成すれば、ダンパ用のモータなどの駆動装置が２個で済み、コンパクト化とコストダウンを図れる。
【００１１】
このエアコンの運転例を説明すると、換気熱回収冷暖房運転では、全てのダンパ１５、１６、１７、１８を開き、還気取入口２からの還気と外気取入口４からの外気を所定割合で混合して蒸発器６で熱交換し、冷風又は暖風を給気口５から給気し、同時に還気取入口２からの還気と外気取入口４からの外気で凝縮器９の循環冷媒を熱交換して吸熱又は放熱し、排熱回収しつつ排気口３から屋外へ室内空気を所定量排気する。このとき、排気用還気ダンパ１６と給気用外気ダンパ１７を全閉し、還気のみを蒸発器６で熱交換し、外気のみを凝縮器９で熱交換することにより、還気循環冷暖房運転やウォーミングアップ運転を行える。
【００１２】
過冷却・除湿・再熱運転では、給気送風路Ａの空気を蒸発器２で過冷却・除湿した後、再熱器７で再熱していわゆるドライエアーを給気し、同時に排気送風路Ｂの空気で凝縮器９の循環冷媒を熱交換し屋外へ排気する。この場合、再熱のために別個に加熱源が不要でかつ凝縮器負荷が下がり省エネとなる。なお過冷却・除湿する空気は、還気のみ、外気のみ、還気と外気の混合空気、の何れであっても良い。換気運転及び外気冷房運転では、圧縮機１４を止めて給気用還気ダンパ１５と排気用外気ダンパ１８を全閉し、給気用外気ダンパ１７から外気のみを室内へ給気し、排気用還気ダンパ１６から還気のみを屋外へ排気する。このようにして無駄に圧縮動力及び送風動力を使わずに省エネを図る。
【００１３】
なお、図例のように排気口３が上で給気口５が下になるようにケーシング１を直立設置すれば床下給気が容易となるが、給気送風路Ａと排気送風路Ｂを上下逆にして（例えば上から下へ給気ファン８、再熱器７、蒸発器６、圧縮機１４、凝縮器９、排気ファン１０の順に配置して）排気口３が下で給気口５が上になるようにケーシング１を直立設置するも自由である。また、ケーシング１の長手方向が横倒状になるように構成して、設置するも自由である。
【００１４】
【発明の効果】
請求項１の発明では、一体形で細長状なので設置面積をとらずにすみ、室内などのデッドスペースを有効活用でき、柱面などの幅の狭い場所などの設置に最適である。給気送風路Ａへの外気取入と排気送風路Ｂへの外気取入を一つの外気取入口４で共用できかつ給気送風路Ａへの還気取入と排気送風路Ｂへの還気取入を一つの還気取入口２で共用できるので、部品点数が減少しコンパクト化とコスト削減を図れ施工が容易となる。ケーシング１から分流チャンバ１１を取出すことによりできた空間をメンナンスホールとして使用でき、各種メンテナンスをケーシング１を分解せずに行えて作業性がよい。１台のエアコンで、還気循環冷暖房運転、換気熱回収冷暖房運転、外気冷房運転、換気運転、過冷却・除湿・再熱運転などの各種パターンの運転ができる。分流チャンバ１１をコンパクトにできるうえに、送風抵抗のない滑らかな拡径状の還気路１９、２０及び外気路２１、２２と成り、還気と外気を圧力を損なうことなくスムーズに給気送風路Ａと排気送風路Ｂへ取入れることができる。
請求項２の発明では、床２３からの輻射空調に加えて、居住外空間である室内上層部を除いた床乃至室内中層域までの居住空間のみで空調空気を循環させることにより、同能力の場合は空調面積を広くとれ、空調面積が同じの場合は省エネとなる。空調のみならず床下空間の換気も行える。
請求項３の発明では、圧力損失が減少して熱交換効率が向上するので小型のファン８、１０を用いることができ騒音低減を図れる。蒸発器６と凝縮器９と再熱器７も小型化できエアコンをコンパクト化できる。

This air conditioner has an elongated box shape having an exhaust port 3, an air supply port 5, a return air intake port 2, and an outside air intake port 4. In the casing 1, a refrigerant circulation circuit 13, an exhaust air passage B provided with a condenser 9 and an exhaust fan 10, an air supply air passage A provided with an evaporator 6, a reheater 7 and an air supply fan 8, , Provided between the air supply air passage A and the exhaust air air passage B to divert the outside air into the air supply air passage A and the air exhaust air passage B and return air to the air supply air passage A and the air exhaust air passage B.

An exhaust air passage B that communicates with the exhaust port 3, a branch chamber 11 that communicates with the return air inlet 2 and the outside air inlet 4, and a supply air passage A that communicates with the air inlet 5 are arranged in series. Solid and dotted white arrows indicate the wind direction.
[0006]
The shunt chamber 11 supplies the return air taken from the return air damper 15, the exhaust air return damper 16, the air supply outside air damper 17, the exhaust air outside damper 18, and the return air intake 2. An air supply return air passage 19 that leads from the damper 15 to the air supply air passage A; an exhaust air return passage 20 that guides the return air taken in from the return air inlet 2 from the exhaust air return damper 16 to the exhaust air passage B; In addition, the outside air passage 21 that leads the outside air taken in from the outside air inlet 4 to the air supply passage A from the outside air damper 17 for supplying air and the outside air that is taken in from the outside air inlet 4 are exhausted from the outside air damper 18 for exhaust.

The return air dampers 15 and 16 are provided at the air inlets of the return air passages 19 and 20, and the outside air dampers 17 and 18 are provided at the air inlets of the outside air passages 21 and 22. This diversion chamber 11 is provided integrally with a partition member and dampers 15, 16, 17, 18, etc., and is configured to be able to be taken out and stored with respect to the casing 1.
[0007]
The air supply port 5 is provided at the lower end portion of the casing 1 so as to communicate with the floor under the floor radiation air conditioning, and the air supplied from the air supply port 5 is blown into the floor 23 or the vicinity of the indoor floor. The air outlet 12 is provided. On the lower surface of the floor 23, a large number of rod-shaped heat transfer bodies 24 that are in contact with the supply air are suspended via a heat storage material 25 while being spaced apart from each other, and the lower ends of the heat transfer bodies 24. A pressure gap is prevented and a turbulent flow effect is obtained. A heat insulating material 26 is provided on the floor slab portion to enhance the heat storage effect, and air is supplied into the floor to bring it into contact with the heat transfer bodies 24 ... and the heat storage material 25, and the heat supplied to the floor 23 is transmitted and radiated. While air conditioning, the air supply is circulated from the air outlet 12 to the return air intake 2 to air-condition the room. Since the supply air is used as the radiant heat source in this way, it is possible to reduce the running cost and the equipment cost because there is no need for a separate device or heat source such as an electric heater or a cold / hot water pipe. Heat exchange between the air supply and the floor portion can be efficiently performed through the heat transfer body 24 to perform floor radiant air conditioning. Moreover, since the heat transfer body 24 is formed in a bar shape, pressure loss is reduced. Further, if the heat storage material 25 is interposed between the heat transfer body 24 and the floor 23, heat is evenly transferred to the entire floor, floor radiation air conditioning can be performed uniformly, and the amount of radiation heat and radiation time can be adjusted. In addition, the heat storage material 25 may be omitted and the heat transfer body 24 may be suspended directly on the lower surface of the floor 23. Further, the heat storage material 25, the heat transfer bodies 24, and the heat insulating material 26 may be omitted (see FIG. 4). In the illustrated example, an exhaust port 3 is formed at the distal end (upper end) of the casing 1, and an air supply port 5 is formed at the proximal end (lower end), respectively, on an appropriate surface (for example, an opposing surface) of the trunk of the casing 1. Although the outside air intake 4 and the return air intake 2 are formed, as shown in FIGS. 1, 4, and 5, their positions can be changed freely. The exhaust port 3 and the outside air intake port 4 are communicated with the outside through a duct or a gargle.
[0008]
The refrigerant circulation circuit 13 is formed by connecting an evaporator 6, a condenser 9, a reheater 7, a compressor 14, a liquid receiver (not shown), an expansion valve, a forward / reverse switching valve in the refrigerant circulation direction, and the like. The heat absorption and heat dissipation of the evaporator 6 and the condenser 9 are configured to be switchable. The reheater 7 is provided leeward of the evaporator 6, and a part of the refrigerant (hot gas) flowing through the condenser 9 is bypassed to the reheater 7 so as to be freely cooled, dehumidified, and reheated. The fin tubes of the evaporator 6, the condenser 9, and the reheater 7 are preferably elliptical tubes, but may be circular tubes.
[0009]
A suction-type air supply fan 8 is provided leeward of the evaporator 6 and the reheater 7, and a suction-type exhaust fan 10 is provided leeward of the condenser 9. Parts of the refrigerant circulation circuit 13 such as a vessel are provided. The exhaust fan 10, the condenser 9, the compressor 14, the evaporator 6, the reheater 7, and the air supply fan 8 are arranged in a straight line and housed in the elongated casing 1 for compactness. In addition, arrangement | positioning of the evaporator 6, the reheater 7, the air supply fan 8, the condenser 9, the exhaust fan 10, the compressor 14, etc. can also be made into things other than the example of a figure. Although not shown, it is also possible to provide a humidifier on the lee of the reheater 7. The refrigerant circuit 13 can be provided integrally with a frame (not shown) so that it can be taken out and stored in the casing 1, and only the refrigerant circuit 13 can be taken out from the casing 1 without removing the entire casing. Refrigerant recovery work and maintenance can be performed easily, and installation and storage are not time-consuming. Further, by replacing only the refrigerant circulation circuit 13, it is possible to reduce the cost at the time of renewal.
[0010]
The return air damper 15 for supply air, the return air damper 16 for exhaust, the outside air damper 17 for supply, and the outside air damper 18 for exhaust perform air volume control by various operation control devices and the like. Each of the dampers 15, 16, 17, and 18 may have any structure in which only the full-close / full-open switching or the arbitrary air volume can be varied. For example, the supply return air damper 15 and the exhaust outside air damper 18 are linked. If it is configured to open and close, and the exhaust return air damper 16 and the supply outside air damper 17 are configured to open and close together, only two drive devices such as a motor for the damper are required, thereby reducing the size and cost. I can plan.
[0011]
Explaining the operation example of this air conditioner, in the ventilation heat recovery air conditioning operation, all the dampers 15, 16, 17, 18 are opened, and the return air from the return air intake 2 and the outside air from the outside air intake 4 at a predetermined ratio. After mixing and exchanging heat with the evaporator 6, cold air or warm air is supplied from the air supply port 5, and at the same time, the return refrigerant from the return air intake 2 and the outside air from the outside air intake 4 are circulating refrigerant in the condenser 9. Heat is exchanged to absorb or dissipate heat, and exhaust air is exhausted to exhaust the indoor air from the exhaust port 3 to the outside. At this time, the exhaust return air damper 16 and the supply outside air damper 17 are fully closed, only the return air is heat-exchanged by the evaporator 6, and only the outside air is heat-exchanged by the condenser 9. Driving and warming up can be performed.
[0012]
In the supercooling / dehumidification / reheat operation, the air in the air supply air passage A is supercooled / dehumidified in the evaporator 2 and then reheated in the reheater 7 to supply so-called dry air, and at the same time the exhaust air passage B The refrigerant in the condenser 9 is heat-exchanged with the air and exhausted outdoors. In this case, a separate heating source is not required for reheating, and the condenser load is reduced to save energy. The air to be supercooled / dehumidified may be only return air, only outside air, or mixed air of return air and outside air. In the ventilation operation and the outside air cooling operation, the compressor 14 is stopped, the supply return air damper 15 and the exhaust outside air damper 18 are fully closed, and only the outside air is supplied from the supply outside air damper 17 into the room for exhaust. Only the return air is exhausted from the return air damper 16 to the outside. In this way, energy is saved without wastefully using compression power and blowing power.
[0013]
In addition, if the casing 1 is installed upright so that the exhaust port 3 is on the top and the air supply port 5 is on the bottom as shown in the figure, the underfloor air supply becomes easy, but the supply air passage A and the exhaust air passage B are connected. Upside down (for example, from the top to the bottom, the air supply fan 8, the reheater 7, the evaporator 6, the compressor 14, the condenser 9, and the exhaust fan 10 are arranged in this order), and the exhaust port 3 is at the bottom. It is also free to install the casing 1 upright so that 5 is on top. Further, the casing 1 can be configured and installed such that the longitudinal direction of the casing 1 is in a horizontal shape.
[0014]
【The invention's effect】
In the invention of claim 1, since it is an integrated and elongated shape, it does not take up an installation area, and it is possible to effectively use a dead space such as a room, and is optimal for installation in a narrow place such as a column surface. The outside air intake to the air supply air passage A and the outside air intake to the exhaust air air passage B can be shared by one outside air inlet 4, and the return air intake to the air supply air passage A and the return to the exhaust air passage B Since the air intake can be shared by one return air intake 2, the number of parts is reduced, and the construction can be facilitated by reducing the size and cost. The space created by taking out the diversion chamber 11 from the casing 1 can be used as a maintenance hole, and various maintenance can be performed without disassembling the casing 1 so that the workability is good . With one air conditioner, various patterns of operation such as return air circulation air conditioning operation, ventilation heat recovery air conditioning operation, outdoor air cooling operation, ventilation operation, subcooling, dehumidification, and reheating operation can be performed. In addition to making the shunt chamber 11 compact, the return air passages 19 and 20 and the outside air passages 21 and 22 have a smooth diameter without air blowing resistance, and the supply air and the outside air are smoothly supplied without impairing the pressure. It can be taken into the passage A and the exhaust air passage B.
In the invention of claim 2 , in addition to the radiation air conditioning from the floor 23, the conditioned air is circulated only in the living space from the floor excluding the indoor upper layer, which is a non-residential space, to the middle middle area of the room. In this case, the air-conditioning area can be increased, and when the air-conditioning area is the same, energy saving is achieved. In addition to air conditioning, it can ventilate the space under the floor.
