【発明の属する技術分野】
本発明は、一つの室内に複数の個別吹出口と中央吹出口とを設けた個別空調システムの技術分野に属する。
【0002】
【従来の技術】
従来、例えば、特許文献1に示されるように、病院等の複数ベッドを配置した広い一つの室内の空調を均一に行うために、複数の領域の天井に個別吹出口を設け、個別吹出口からの送風量が均一になるように送風分配器を設けた個別空調システムが知られている。
また、一つの空調機の送風機から、一つの室内ではなく複数の部屋に調和空気を供給し、各部屋の吹出口のダンパの開度を制御する空調システムも、例えば、特許文献2、特許文献3等に開示されている。

【発明が解決しようとする課題】
しかしながら、病院等の複数ベッドを配置した広い一つの室内でも、ベット毎が患者が必要とする空調環境には個人差があり、複数の領域ごとにきめ細かい空調環境の調整を行うことは不可能であった。
これを克服するために、従来では図4に示すように、病室oの複数の領域毎の複数の吹出口(p1〜 p4)に連なるダクト(q1〜q4)毎に、室外のファンコイルユニットrには個別のファン(s1〜s4)を設けて、この個別のファン毎に回転数をリモートコントローラーtなどで制御する空調システムも考えられるが次のような問題点がある。
(1)ファンコイルユニットrの寸法が大きくなり、設置場所が制限される。
(2)据え付け工事や、更新工事も大掛かりとなる。
(3)送風機が各空調対象毎の複数必要な為、消費電力が大きくなる。
(4)送風機が空調対象分あるため、広い保守点検スペースの確保が必要となる。
(5)個人毎に風量を変えてしまう為、部屋全体の室温制御が難しい。
また、特許文献2,3に示されるような部屋別の制御システムを、一つの室内の複数領域の制御に転用することも考えられるが、前記の(4)の問題点は解消しない。
【0005】
本発明は、上記の問題点に鑑みてなされたもので、その課題は、広い一つの室内の領域ごとに、調和空気の制御が可能であり、しかも、室全体の室温制御が容易であり、装置自体の簡単で据え付けや保守が簡単な個別空調システムを提供するものである。
【0006】
上記の課題を解決するために、請求項1の発明は、上記の課題を解決するために、請求項1の発明は、一つの室内に空調機から単一ダクトで送風される調和空気を複数の個別吹出口と中央吹出口とから分配供給する空調システムにおいて、該個別吹出口にはそれぞれに独立して風量を調節する風量調整機構を設け、該中央吹出口にはダクト内の圧力を一定に維持する定圧機構を設けたことを特徴とする個別空調システムである。
請求項2の発明は、前記定圧機構は、ダクト内のダンパが受ける圧力とこれに抗する力とをバランスさせてダンパの開度を自動的に変えることを特徴とする請求項1に記載の個別空調システムである。
請求項3の発明は、前記空調機の調和空気は、室内または還気の状態を感知して制御されることを特徴とする請求項1または請求項2に記載の個別空調システムである。
請求項4の発明は、前記風量調整機構は、ダンパの開度を変えることによって個別に制御されることを特徴とする請求項1乃至請求項3に記載の個別空調システムである。
【0007】
【発明の実施の形態】
本発明の好適な空気調和機の1実施例を図面に沿って説明する。
図1は本実施例の個別空調システムの全体を示すもので、符号1は、病院の4ベッドを病室の4隅に配置した4床病室を示したものであり、この4床病室1には各4ベッドに対応した位置の天井部分に、4つの個別吹出口2(2A,2B,2C,2D)が配置され、病室中央の共通領域の天井には中央吹出口3(室内用吹出口)が配置されている。
これらの個別吹出口2と中央吹出口3とは、室外のファンコイルユニット4から1本のダクト5で連結され、ダクト5は4つの個別吹出口2と中央吹出口3とに分岐して、各吹出口2、3は互いに連結している。
ここで、4つの個別吹出口2(2A,2B,2C,2D)は、実際には病室の個人ベッド用吹出口として機能しているが、後述する個人用手元コントロールスイッチ6で風量調節を行えるように構成され、中央吹出口3には後述するダクト内の圧力を一定に維持する定圧維持機構7が設けられている。
ファンコイルユニット4は、外気や室からの還気を送風機により送風量を制御しコイルで空調した空気をダクト5を介して室内に供給するが、温度センサーを配備した室内コントローラ8とパワーユニット9とによって制御される。
次に、各機構について、具体的に説明する。
【0008】
[個別吹出口]
図2は、4つの個別吹出口2(2A,2B,2C,2D)の内の1つの内部を示す図で、図2(a)は上面からの図、図2(b)は側面からの図であるが、個別吹出口2はベッドに対応した位置の天井部分F1に取り付けられている。調和された空気はダクト5から供給(図2矢印a)されるが、まず、個人用手元コントロールスイッチ(SW)6で制御される風量調整機構21よって風量が調節される。この風量調整機構21はダンパ22の開度によって調整されるが、ダンパ22はダンパモータ23の回動により回動する回転軸24を中心に一対のダンパ板25が回動(図2矢印x)し、ダクト5の側壁51とダンパ板25の端部251との隙間の間隔yを調節することにより行い、この隙間によって風量を調節された調和空気(図2矢印b)は、下端に配置された風向調整デフレクター26によって室内への風向きを調整して天井パネル27から個人のベットの領域に給気される(図2矢印c)。このとき、ダンパモータ23の回動の度合いは個人の手元に配置されたコントロールスイッチ6でベッドにいる個人の手動により個々に制御される。
【0009】
[中央吹出口]
図1および図3における中央吹出口3は、4床病室1のパブリックスペースである中央通路のスペースのほぼ中央の位置の天井部分F2に取り付けられている。図3は中央吹出口3とその近傍で中央吹出口3に連なるダクト5内の定圧維持機構7の側面の図である。
定圧維持機構7は調和された空気が、ダクト5から供給(図3矢印a)される送風aの圧力を利用してダクト5内の圧力を一定に保つものであるが、送風の圧力を受けるダンパ板71は一端に回動軸72が設けられ、この回動軸72はダクト5の側壁52の適所に設けられた軸受部材73に回動自在(図3矢印C方向)に軸支されており、ダクト5の下面のほぼ中央には長手方向に延びることが可能な収縮型のバネ74が係止部材75を介して係合されており、バネ74の他端はダクト5の側壁53の適所に、バネ張力調整機構76を介して係合されている。
したがって、ダクト5内の圧力が小さい時は、バネ74の引張力によってダンパ板71は側壁53(図3下側)側の閉じる方向に回動し(図3符号A)、結果としてダクト5内の全体の圧力は高まるように作用する。逆に、ダクト5内の圧力が大きい時は、圧力aはバネ74の引張力に抗してダンパ板71を側壁52(図3上側)側の開口方向に回動し(図3符号B)、結果としてダクト5内全体の圧力は下がるように作用する。
そして、ダンパ板71の回動される端とダクト5の側壁53の隙間を風量調整された調和空気は中央吹出口3に導かれ、その下端に配置された風向調整デフレクター31や風向ガイド32によって室内への風向きを調整して天井パネル33から共通スペースの領域に給気される(図3矢印c)。
なお、この定圧維持機構7のバネ張力調整機構76として固定位置が変更可能なバネ係止棒体761が設けられ、バネ74の端部を左右移動(図3矢印z)させ、バネ74の張力を調整して固定するものである。また、本実施例の定圧維持機構7はバネを用いたが、重り等を用いた重力型にしても良く、能動的に油圧等で作動する定圧維持機構を採用してもよい。
【0010】
[ファンコイルユニット]
図1において、ファンコイルユニット4は、外気や室からの還気をエアフィルター41を介して、送風機42により送風量を制御してコイル43で暖房または冷房で空調してダクト5から室内に供給する。この際、送風量を司る送風機42やコイル43の暖房または冷房の媒体循環量を司るバルブ44はパワーユニット9の出力信号によって制御されるが、あくまでも病室全体としての管理となる。
これは、前記パワーユニット9の入力として還気温度センサー91および給気温度センサー92からの値と、室内温度センサー(図示せず)を配備した室内コントローラ8との入力値から算出される。なお、病室全体の温度としては還気温度センサー91の値に換えて室内温度センサー(図示せず)にしてもよく、これらの組み合わせでもよい。
本実施例では、行っているが、これは送風機42の効率が高く維持コストが低くでき、メンテナンスも容易だからである。したがって、室内コントローラ8も所望の室内温度を指定すれば各温度センサーの値から、高/中/低の三速から所定の速度を選び出して運転する。また、手動の場合も、風量強制運転ボタンを設けられ、高/中/低の三速から所定の速度を選び出し、その風量で連続運転させることができる。
また、パワーユニット9によるバルブ44は、給気温度が予め設定された温度となるようにバルブ44を比例制御する。
【0011】
[作動]
本発明の実施例の作動を説明するが、4床病室1おいて、4つの個別吹出口2(2A,2B,2C,2D)が、それぞれ独自に手元コントロールスイッチ6で風量調整機構21よって風量を調節しても、4床病室1の全体として風量を変更する必要がなければ、ファンコイルユニット4の稼働状態を一定に維持することで、送風機42に不必要な作動を避けたものでる。このために、各個別吹出口2での必要とされる風量を確保し、その変化分を、通常は風量のきめ細かな調整の必要のない病室の中央通路のスペースの中央吹出口3が吸収するようにしたシステムである。
このことを具体的に説明すると、いま、4つの個別吹出口2のうち1つの個別吹出口2Aにおいて、手元コントロールスイッチ6で風量調整機構21よって、ダンパ22の開度をダンパモータ23の回転軸24を回動させ、ダクト5の側壁51とダンパ板25の端部251との隙間の間隔yを大きくして、風量を増してこのベッド領域の空調環境を変化させると、ダクト5内の全体の圧力は一時的に下がるが、中央吹出口3の近傍に配置された定圧維持機構7が作動し、定圧維持機構7のバネ74の引張力によってダンパ板71は側壁53の閉じる方向に回動し(図3符号A)、結果としてダクト5内全体の圧力は元にもどる。
したがって、還気温度センサー91や室内温度センサー(図示せず)の検出値が同じであれば送風機42の送風量はほぼ同じであるが、中央吹出口3の風量は小さくなって、他の4つの個別吹出口2では必要とされる風量が確保されることになる。
【0012】
ここで、4床病室1の全体の空調環境を還気温度センサー91や室内温度センサー(図示せず)よって感知し、これに基づいてパワーユニット9の稼働指令により送風機42の高/中/低の設定が変ると、その送風機42の設定された速度で連続運転をし送風量も一定となるが、この状態でも4床病室1は前述したように4つの個別吹出口2が、独立して風量調整機構21よって風量を調節しても、ファンコイルユニット4の送風機42の速度を変える必要がない。
また、手動の場合は風量強制運転ボタンによって、高/中/低の三速から所定の速度を設定し、その風量で連続運転させることができるが、この場合も同様に作動する。
本実施例は上記のような構成であるから、広い一つの病室内の領域ごとに、各ベッドの領域毎に独立して調和空気の個別制御が可能であり、しかも、病室全体の温度制御が容易であり、送風機の一定回転をより長時間維持できるので安定した空調運転となり、装置自体の簡単で据え付けや保守が簡単である。
【0013】
なお、本発明の特徴を損うものでなければ、上記の実施例に限定されるものでないことは勿論である。例えば、病室を4ベッドとしたが、これ以外の複数のベット数に対応して複数個別吹出口として、これらと中央吹出口との組み合わせにしても良いことは勿論であり、病院以外でも複数領域を独立して空調管理する事務所等に用いても良いことも勿論である。
【0014】
【発明の効果】
以上説明したように、本発明は、広い一つの室内の領域ごとに、独立して調和空気の個別制御が可能であり、しかも、室全体の室温制御が容易であり、送風機の一定回転をより長時間維持できるので安定した空調運転となり、装置自体の簡単で据え付けや保守が簡単な個別空調システムであるという効果が得られる。

[0007]
DETAILED DESCRIPTION OF THE INVENTION
One preferred embodiment of an air conditioner of the present invention will be described with reference to the drawings.
FIG. 1 shows the entire individual air conditioning system of this embodiment. Reference numeral 1 shows a four-bed hospital room in which four beds of a hospital are arranged at four corners of a hospital room. Four individual outlets 2 (2A, 2B, 2C, 2D) are arranged on the ceiling corresponding to each of the four beds, and the central outlet 3 (indoor outlet) is located on the ceiling in the common area in the center of the hospital room. Is arranged.
These individual air outlets 2 and the central air outlet 3 are connected by one duct 5 from the outdoor fan coil unit 4, and the duct 5 branches into four individual air outlets 2 and the central air outlet 3, The air outlets 2 and 3 are connected to each other.
Here, the four individual air outlets 2 (2A, 2B, 2C, 2D) actually function as personal bed air outlets in the hospital room, but the air volume can be adjusted by the personal hand control switch 6 described later. The central air outlet 3 is provided with a constant pressure maintaining mechanism 7 that maintains a constant pressure in the duct, which will be described later.
The fan coil unit 4 supplies outside air or return air from the room with a blower to control the amount of air blown and air-conditioned by the coil into the room through the duct 5. Controlled by.
Next, each mechanism will be specifically described.
[0008]
[Individual outlet]
2 is a diagram showing the inside of one of the four individual outlets 2 (2A, 2B, 2C, 2D), FIG. 2 (a) is a view from the top, and FIG. 2 (b) is a view from the side. Although it is a figure, the individual blower outlet 2 is attached to the ceiling part F1 of the position corresponding to a bed. The conditioned air is supplied from the duct 5 (arrow a in FIG. 2). First, the air volume is adjusted by the air volume adjusting mechanism 21 controlled by the personal hand control switch (SW) 6. The air volume adjusting mechanism 21 is adjusted by the opening degree of the damper 22, and the damper 22 is rotated by a pair of damper plates 25 (arrow x in FIG. 2) about a rotating shaft 24 that is rotated by the rotation of the damper motor 23. The conditioned air (arrow b in FIG. 2) whose air volume has been adjusted by this gap is arranged at the lower end by adjusting the gap y between the side wall 51 of the duct 5 and the end 251 of the damper plate 25. The wind direction adjusting deflector 26 adjusts the wind direction into the room and the air is supplied from the ceiling panel 27 to the area of the individual bed (arrow c in FIG. 2). At this time, the degree of rotation of the damper motor 23 is individually controlled manually by the individual who is in the bed by the control switch 6 disposed at the individual's hand.
[0009]
[Central outlet]
The central outlet 3 in FIGS. 1 and 3 is attached to the ceiling portion F <b> 2 at a substantially central position in the space of the central passage that is a public space of the four-bed hospital room 1. FIG. 3 is a side view of the constant pressure maintaining mechanism 7 in the duct 5 connected to the central air outlet 3 and the central air outlet 3 in the vicinity thereof.
The constant pressure maintaining mechanism 7 keeps the pressure in the duct 5 constant by using the pressure of the blown air a supplied from the duct 5 (arrow a in FIG. 3), but receives the pressure of the blown air. The damper plate 71 is provided with a rotating shaft 72 at one end, and this rotating shaft 72 is pivotally supported by a bearing member 73 provided at an appropriate position on the side wall 52 of the duct 5 (in the direction of arrow C in FIG. 3). A contraction type spring 74 that can extend in the longitudinal direction is engaged through a locking member 75 at the substantially center of the lower surface of the duct 5, and the other end of the spring 74 is connected to the side wall 53 of the duct 5. It is engaged at an appropriate position via a spring tension adjusting mechanism 76.
Therefore, when the pressure in the duct 5 is small, the damper plate 71 is rotated in the closing direction on the side wall 53 (lower side in FIG. 3) by the tension force of the spring 74 (reference numeral A in FIG. 3). The overall pressure of the urine acts to increase. On the other hand, when the pressure in the duct 5 is large, the pressure a rotates the damper plate 71 in the opening direction on the side wall 52 (upper side in FIG. 3) against the tensile force of the spring 74 (reference numeral B in FIG. 3). As a result, the pressure in the entire duct 5 acts to decrease.
The conditioned air whose air volume has been adjusted through the gap between the rotating end of the damper plate 71 and the side wall 53 of the duct 5 is guided to the central outlet 3 and is adjusted by the wind direction adjusting deflector 31 and the wind direction guide 32 disposed at the lower end thereof. The air direction into the room is adjusted and air is supplied from the ceiling panel 33 to the common space area (arrow c in FIG. 3).
In addition, a spring locking rod 761 whose fixing position can be changed is provided as the spring tension adjusting mechanism 76 of the constant pressure maintaining mechanism 7, and the end of the spring 74 is moved to the left and right (arrow z in FIG. 3) to thereby adjust the tension of the spring 74. Is fixed by adjusting. Further, although the constant pressure maintaining mechanism 7 of the present embodiment uses a spring, it may be a gravity type using a weight or the like, or a constant pressure maintaining mechanism that is actively operated by hydraulic pressure or the like may be employed.
[0010]
[Fan coil unit]
In FIG. 1, the fan coil unit 4 supplies the outside air or the return air from the room through the air filter 41, the air volume is controlled by the blower 42, air-conditioned by heating or cooling by the coil 43, and supplied from the duct 5 to the room. To do. At this time, the blower 42 that controls the amount of air flow and the valve 44 that controls the medium circulation amount of the heating or cooling of the coil 43 are controlled by the output signal of the power unit 9 but are managed as a whole hospital room.
This is calculated from the values from the return air temperature sensor 91 and the supply air temperature sensor 92 as inputs to the power unit 9 and the input value from the indoor controller 8 provided with an indoor temperature sensor (not shown). The temperature of the entire hospital room may be a room temperature sensor (not shown) instead of the value of the return air temperature sensor 91, or a combination thereof.
In the present embodiment, this is done because the efficiency of the blower 42 is high, the maintenance cost can be lowered, and maintenance is easy. Therefore, the indoor controller 8 also operates by selecting a predetermined speed from the three speeds of high / medium / low based on the value of each temperature sensor if a desired room temperature is designated. In the case of manual operation as well, an air volume forced operation button is provided, and a predetermined speed can be selected from three speeds of high / medium / low, and continuous operation can be performed with the air volume.
The valve 44 by the power unit 9 proportionally controls the valve 44 so that the supply air temperature becomes a preset temperature.
[0011]
[Activation]
The operation of the embodiment of the present invention will be described. In the four-bed hospital room 1, four individual air outlets 2 (2A, 2B, 2C, 2D) are independently controlled by the air volume adjusting mechanism 21 with the hand control switch 6, respectively. If the air volume does not need to be changed as a whole of the four-bed hospital room 1 even if the adjustment is performed, unnecessary operation of the blower 42 is avoided by maintaining the operating state of the fan coil unit 4 constant. For this purpose, the required air volume at each individual air outlet 2 is secured, and the change is absorbed by the central air outlet 3 in the space of the central passage of the hospital room, which normally does not require fine adjustment of the air volume. This is the system.
More specifically, now, in one of the four individual outlets 2, the opening degree of the damper 22 is controlled by the air volume adjusting mechanism 21 with the hand control switch 6 at the rotary shaft 24 of the damper motor 23. Is turned, the gap interval y between the side wall 51 of the duct 5 and the end 251 of the damper plate 25 is increased, and the air volume is increased to change the air conditioning environment of the bed area. Although the pressure temporarily decreases, the constant pressure maintaining mechanism 7 disposed in the vicinity of the central outlet 3 operates, and the damper plate 71 rotates in the closing direction of the side wall 53 by the tensile force of the spring 74 of the constant pressure maintaining mechanism 7. As a result, the pressure in the entire duct 5 is restored.
Therefore, if the detection values of the return air temperature sensor 91 and the indoor temperature sensor (not shown) are the same, the air flow rate of the blower 42 is substantially the same, but the air flow rate of the central outlet 3 becomes smaller, and the other 4 The required air volume is secured at the two individual outlets 2.
[0012]
Here, the entire air-conditioning environment of the four-bed hospital room 1 is sensed by a return air temperature sensor 91 and a room temperature sensor (not shown), and based on this, the high / medium / low of the blower 42 is determined by the operation command of the power unit 9. When the setting changes, the continuous operation is performed at the set speed of the blower 42 and the air flow rate becomes constant. Even in this state, the four-bed hospital room 1 has four air outlets 2 independently as described above. Even if the air volume is adjusted by the adjusting mechanism 21, it is not necessary to change the speed of the fan 42 of the fan coil unit 4 .
In the case of manual operation, a predetermined speed can be set from high / medium / low three speeds by means of a forced air volume operation button, and continuous operation can be performed with that air volume.
Since the present embodiment is configured as described above, it is possible to individually control the conditioned air independently for each area of each bed for each area of a wide room, and to control the temperature of the entire room. It is easy, and since the constant rotation of the blower can be maintained for a longer time, the air conditioning operation is stable, and the apparatus itself is simple and easy to install and maintain.
[0013]
Needless to say, the present invention is not limited to the above-described embodiments as long as the features of the present invention are not impaired. For example, although the hospital room has 4 beds, it is of course possible to use a combination of these and the central air outlet as a plurality of individual air outlets corresponding to a plurality of other bet numbers. Of course, it may be used in an office or the like that independently manages air conditioning.
[0014]
【The invention's effect】
As described above, the present invention enables independent control of the conditioned air independently for each wide indoor area, and further facilitates room temperature control of the entire room, and further improves the constant rotation of the blower. Since it can be maintained for a long time, the air conditioning operation is stable, and the effect is that the device itself is an individual air conditioning system that is easy to install and maintain.
