Description

【0001】
【産業上の利用分野】
この発明は空気調和設備に使用される天井型のファンコイルユニットに関する。
【0002】
【従来の技術】
在来空気調和設備と照明器具の関連では照明器具に空気調和設備の空気吹出口または空気吸込口を組み込んだ商品は周知の存在であるが、送風機、熱交換器を組み込んでファンコイルユニットと照明器具を一体化したものは存在しない。
【0003】
【発明が解決しようとする課題】
空気調和設備は近年オフィスオートメションが進むにつれて、または百貨店などの売り場でも照明器具、ショウケースの電力が増加して室内の熱負荷が大きくなり、それに伴って空調風量が増加する傾向にある。照明器具も同時に増加する傾向があり、且つ両者とも室内に平面的に出来るだけ均一に配置する事が必要であるため配置上の取り合いがしばしば問題となる。
【0004】
照明の照度が増加するに従って空調負荷の中で照明の発熱の占める割合が増し、その分だけ風量を増加させる必要がある。そのため照明器具に吸込口を取り付けて照明器具の表面から発生する熱を還気に直接持ち去らせて、風量の増加を抑えるなどの試みは以前からなされているが、還気ダクトと照明器具を連結するのはコスト的に困難が大きく、実際には使用されていない。従って、照明器具の増加に比例して空調風量は増加の傾向にあり、送風機電力の増加にも繋がっている。
【0005】
【課題を解決するための手段】
本発明では蛍光灯照明器具と空気調和設備のファンコイルユニットを一体化し両者の取り合いの原因となる平面的寸法から見ると、照明器具の化粧板の寸法を殆んど増加させずに吹出口を設けられるため、両者の取り合いは生じないで済む。
【0006】
本発明では照明器具と送風機、熱交換器を一体化して組み込んでいるため、照明器具の表面からの発熱を器具の中で空気を循環冷却できるので、照明器具の表面からの発熱は熱交換器の負荷には加わるが、室内空気冷却負荷には算入されず、冷却のための風量をその分だけ節減でき、さらに送風機電力も節約できる。
【0007】
【作用】
蛍光灯照明器具は平面寸法は大きいが器具としての高さは少なく、天井面から下方に出ても、逆富士型の蛍光灯照明器具のごとく問題は無く、化粧板の一部分に吹出口を設けても殆ど面積に影響を及ぼさない。
【0008】
ファンコイルユニットとしてもアウターローター型モーター直結の輻流送風機または軸流送風機を軸垂直に使用し、前記送風機の吐き出し側の与圧チャンバー下方にフィンチューブ型熱交換器を設置すれば実用的に150mm程度の高さでファンコイルユニットを構成出来るので、設置寸法として有利である。
【0009】
さらに、照明器具とファンと熱交換器が一体化設置されているので、照明器具表面からの発熱を室内に放散せずに、照明器具の上面から気流の通路を設け、前記気流を輻流送風機のディスク中心部付近の開口部から吸い込ませて、直接に熱交換器に吸収させる事ができるので、照明負荷の殆んどを占める器具表面からの発熱を室内空調熱負荷に加える必要が無く、在来より表面発熱量相当分だけ風量を減らす事ができる。軸流送風機の場合にはモータ自体に通風冷却機能を持たせて、該モータの通風力を利用して照明器具などの発熱を吸収して熱交換器上流側に移送して同様の効果を挙げることも出来る。
【0010】
【実施例】
図面により本発明の実施例について説明する。
【図 1】は本発明の実施例の断面図を示す。図中1は出力1.5W、外径40mmφのアウターローター型モーター2のローター3に取り付けた外径125mmφの輻流送風機4の翼車で上部に樹脂製の高さ36mmの放射状の36枚の羽根5を持ち断面中心に配置され、これが回転する事によって幅165の与圧チャンバー6の天板7の保護網8を取り付けた円形の開口部9から天井懐10を介して室内からの還気を吸い込み、遠心力によって前記輻流送風機4の翼車1の外周から与圧チャンバー6内部に吐出する。
【0011】
与圧チャンバー6は下方にある長さ1250mmの蛍光灯の管球11と平行に略中心を揃え、長さを950mmとし上面の幅15mmを持ち左右下方に開いたアルミ押出し成型材料によるファン共通架台12の上に5台の輻流送風機4が等間隔に設置され、その下方には左右対象に与圧チャンバー6の全長に亙る2本のフィンチューブ熱交換器13をフィンの下辺14が中央の前記ファン共通架台12に向けて下り勾配になるように配置し、天板7に連なる左右の側板15は蛍光灯照明器具の化粧板16に開口した左右2本の空気吹出口17の外側の縁に沿って固定されている。
【0012】
中央のファン共通架台12は下方で左右に拡がり、与圧チャンバー6の左右の側板15と平行に空気吹出口17の25mm幅と同じ間隔を以って平行に空気吹出口17の内側の縁に沿って照明器具の化粧板16固定され、更にファン共通架台12の両側面にはフィンチューブ熱交換器13の下方に全長に亙って気流の妨げにならない位置にドレンパン18が一体成型されている。
【0013】
化粧板16の下面中央には蛍光灯の反射板19が、中央両端部には蛍光灯のソケット20が取り付けられ、蛍光灯の管球11がその間に挿入される。前記反射板19には蛍光灯の管球11の真上に当たる部分に数個の吸込孔21を設けて、前記ファン共通架台12に囲まれる空間部22の下面開口部23と連なる。
【0014】
一方、ファン共通架台12の上面には輻流送風機4の翼車1の下面が1mm以内の間隔で近接していて、各ファンモーターの芯振り分け30mmの位置に直径10mmφの孔を上面開口部24として設ける。輻流送風機4の翼車1には中心から半径30mmの円周上に等分に12個の直径10mmφの下面の孔25を設けてある。
【0015】
輻流送風機4が回転すると遠心力によって翼車1には上部の円形の開口部9から天井懐10を経て室内からの還気を吸い込むと同時に翼車1の12個の直径10mmφの下面の孔25からも空気を吸込む。従って、中央のファン共通架台12の上面開口部24と翼車1の下面の孔25が一致する瞬間はファン共通架台12の内部の空間部22を通じて下面開口部23から空気を吸い込む。
【0016】
この空気の流れは蛍光灯の管球11の表面で加熱された空気を反射板19の数個の吸込孔1からファン共通架台12の内部空間部22に導き、内部空間部22に取り付けられた蛍光灯の安定器26の発熱も吸収し、昇温して輻流送風機4の翼車1を経てフィンチューブ熱交換器13に至り、ここで冷却される結果となり、蛍光灯照明器具表面からの発熱は室内に放散せずに、直接冷却される事になり、室内顕熱負荷にならず、その分だけ室内冷却用の風量を減らす事が出来、さらに蛍光灯照明器の発熱を冷却するための空気は室温に拘わり無く40℃程度まで昇温出来るのでフィンチューブ熱交換器13の有効温度差を増し熱交換性能を向上する。
【0017】
本実施例のファンコイルユニットは近年のオフィスの照明電力が約36W/m、空調負荷が概ね180W/mに近づいている実情に鑑みて、顕熱冷却能力を200ワットとし、天井懐10の空気温度を26℃:47%、比容積0.85m/kg、比熱0.24kcal/kgとし、熱交換器の出口温度を23.5℃とすると照明器具並びに安定器表面からの発熱量40ワットが在来の様に室内に放散される場合の室内の冷却に必要な風量は次式の計算によって200W×0.86W/kcal/h÷(26−23.5)℃÷0.24kcal/kg・℃×0.86m/kg=246m/hとなるが、発熱量40ワットが直接吸収されて冷却されれば室内への必要送風量は246×(200−40)÷200=197m/hとなり、(246−197)/246=0.2、即ち20%の風量の節減になる。
【0018】
蛍光灯の発熱を冷却するための空気は40℃までの温度上昇を許容出来るから40×0.86÷(40−26)÷0.24×0.86=8.8m/hであり、天井懐10からの空気量と前記8.8m/hの合計が197mとなるため熱交換器入口の空気温度は比例配分から計算すると{(197−8.8)×26+8.8x40}÷197=26.6℃となる。
【0019】
本実施例ではフィンチューブ熱交換器13の入口冷水温度は22.5℃、出口冷水温度は24℃を計画しているので、在来の照明器具発熱量が室内に放散する場合のフィンチューブ熱交換器14における対数平均温度差は26−24=2℃並びに23.5−22.5=1℃の間では1.4℃であり本実施例による直接冷却の場合には対数平均温度差は26.6−24=2.6℃並びに23.5−22.5=1℃間で1.67℃となって20%ほど熱交換器の性能が向上する。
【0020】
本実施例による空気調和機は別途室内に導入される外気を低温まで除湿して室内の潜熱負荷を処理する空調方式に使用する事を目的とするため、本来は顕熱専用であるが、特別な集会などで在室者密度が異常に増加した場合は湿度が増加しフィンチューブ熱交換器14に結露する可能性を否定出来ない。そのためにフィンチューブ熱交換器13の傾斜したフィンの最下端の下方にドレンパン18を設けているが、ドレンが溜まるのは異常事態として捉らえ、水分センサー27にてドレンを検知して異常警報を出し、送風機を停止させるようにした。図中28は天井板を示す。
【0021】
【図 2】は前記実施例の輻流送風機4を空力性能を向上するために軸流送風機29に替え、モータ自体に通風冷却機能を持たせて、通風型モータ30とし、下部ブラケット面31の開口部32から空気を吸い込むようにし、この通風力を利用して照明器具の表面からの発熱を吸収した空気を、モータの通風冷却を兼ねて、モータ上部ブラケット33直下の周囲の開口部34から熱交換器上流側へ吐出するようにして、輻流送風機4の場合と同様の効果を挙げることが出来るようにした実施例を示す。
【発明の効果】
本発明は実施例に示すように構成したから在来の照明器具の平面積の内にファンコイルユニットの機能をすべて収めて、空調機器と照明器具との天井での平面的な取り合いを無くし、相互に均等な配置が容易に出来る様に改善された。さらに蛍光灯照明器具の表面からの発熱を直接吸収する事によって室内の顕熱負荷を減らし、20%の風量節減と20%の熱交換器の性能向上を実現した。

[Industrial applications]
The present invention relates to a ceiling type fan coil unit used for an air conditioner.
[0002]
[Prior art]
In the context of conventional air conditioning equipment and lighting equipment, there is a well-known product that incorporates an air outlet or air inlet of an air conditioning equipment into a lighting equipment, but a fan coil unit and lighting are installed by incorporating a blower and heat exchanger. There is no integrated device.
[0003]
[Problems to be solved by the invention]
As for the air conditioning equipment, as office automation advances in recent years, or even at a store such as a department store, the power of lighting equipment and showcases increases, and the indoor heat load increases, and the air conditioning airflow tends to increase accordingly. The number of lighting fixtures also tends to increase at the same time, and both need to be arranged as uniformly as possible in a room in a plane, so that arrangement is often a problem.
[0004]
As the illuminance of the lighting increases, the proportion of heat generated by the lighting in the air-conditioning load increases, and it is necessary to increase the air volume accordingly. For this reason, attempts have been made to attach an air inlet to the lighting fixtures and remove the heat generated from the surface of the lighting fixtures directly to the return air, thereby suppressing an increase in air volume. It is very difficult to do so and it is not actually used. Therefore, the air-conditioning air volume tends to increase in proportion to the increase in the number of lighting fixtures, which leads to an increase in blower power.
[0005]
[Means for Solving the Problems]
In the present invention, the fluorescent lamp lighting device and the fan coil unit of the air conditioner are integrated, and when viewed from the planar dimensions that cause the two to cooperate, the outlet can be increased without increasing the size of the decorative plate of the lighting device. Since they are provided, there is no need for a conflict between the two.
[0006]
In the present invention, since the lighting fixture, the blower and the heat exchanger are integrated and incorporated, heat generated from the surface of the lighting fixture can be circulated and cooled in the fixture. However, it is not included in the indoor air cooling load, and the amount of air for cooling can be reduced by that much, and the power for the blower can be saved.
[0007]
[Action]
Fluorescent lighting fixtures have a large plane size but a small height as an fixture.Even if they go down from the ceiling surface, there is no problem as with inverted Fuji-type fluorescent lighting fixtures. However, it hardly affects the area.
[0008]
As a fan coil unit, a radiant blower or an axial blower directly connected to an outer rotor type motor is used in a direction perpendicular to the axis, and a fin tube type heat exchanger is practically installed 150 mm below the pressurized chamber on the discharge side of the blower. Since the fan coil unit can be configured with a height of about the same, it is advantageous as an installation size.
[0009]
Furthermore, since the lighting fixture, the fan and the heat exchanger are installed integrally, the heat flow from the lighting fixture surface is not dissipated into the room, an airflow path is provided from the upper surface of the lighting fixture, and the airflow is radiated by a radiant blower. It can be sucked from the opening near the center of the disc and absorbed directly into the heat exchanger, so there is no need to add the heat generated from the fixture surface, which accounts for most of the lighting load, to the indoor air conditioning heat load. The air volume can be reduced by the amount equivalent to the surface heat generation from the past. In the case of an axial blower, the motor itself has a ventilation cooling function, absorbs heat generated by lighting equipment and the like by using the ventilation air of the motor, and transfers the heat to the upstream side of the heat exchanger to achieve the same effect. You can do it.
[0010]
【Example】
An embodiment of the present invention will be described with reference to the drawings.
FIG. 1 shows a sectional view of an embodiment of the present invention. In the drawing, reference numeral 1 denotes an impeller of a radiation blower 4 having an outer diameter of 125 mm and attached to a rotor 3 of an outer rotor type motor 2 having an output of 1.5 W and an outer diameter of 40 mm φ. The blades 5 are arranged at the center of the cross section, and when the blades are rotated, air is returned from the room through the ceiling opening 10 through the circular opening 9 to which the protection net 8 of the top plate 7 of the pressurized chamber 6 having a width 165 is attached. And is discharged from the outer periphery of the impeller 1 of the radiant blower 4 into the pressurized chamber 6 by centrifugal force.
[0011]
The pressurized chamber 6 is a fan common mount made of an extruded aluminum material which is substantially parallel to the center of the fluorescent lamp tube 11 having a length of 1250 mm below and has a length of 950 mm, a width of 15 mm on the upper surface, and a left and right lower opening. Five radiant blowers 4 are installed at equal intervals on the upper side 12, and two fin tube heat exchangers 13 extending across the entire length of the pressurized chamber 6 are symmetrically disposed below the lower side 14 of the fins at the center. The left and right side plates 15 which are arranged so as to be inclined downward toward the common fan base 12 and are connected to the top plate 7 are outer edges of two left and right air outlets 17 opened in a decorative plate 16 of a fluorescent lamp lighting fixture. Is fixed along.
[0012]
The central fan common base 12 extends right and left below, and is parallel to the left and right side plates 15 of the pressurized chamber 6 at the same distance as the 25 mm width of the air outlet 17 and parallel to the inner edge of the air outlet 17. Along with the decorative plate 16 of the lighting fixture, a drain pan 18 is integrally formed on both side surfaces of the common fan base 12 at a position below the fin tube heat exchanger 13 so as not to hinder the air flow over the entire length. .
[0013]
A fluorescent light reflecting plate 19 is attached to the center of the lower surface of the decorative plate 16, and fluorescent lamp sockets 20 are attached to both ends of the center, and a fluorescent lamp bulb 11 is inserted therebetween. The reflecting plate 19 is provided with several suction holes 21 at a position directly above the bulb 11 of the fluorescent lamp, and is connected to the lower surface opening 23 of the space 22 surrounded by the common fan base 12.
[0014]
On the other hand, the lower surface of the impeller 1 of the radiant blower 4 is close to the upper surface of the common fan frame 12 at an interval of 1 mm or less, and a hole having a diameter of 10 mmφ is formed at a position of 30 mm for each fan motor. Provided as The impeller 1 of the radiant blower 4 is provided with twelve lower holes 25 each having a diameter of 10 mm on a circumference having a radius of 30 mm from the center.
[0015]
When the radiant blower 4 rotates, the centrifugal force causes the impeller 1 to suck in return air from the room through the ceiling circular opening 9 through the ceiling opening 10 and at the same time, 12 holes of the impeller 1 with a diameter of 10 mmφ on the lower surface. Inhale air from 25 as well. Therefore, when the upper surface opening 24 of the central fan common frame 12 and the hole 25 on the lower surface of the impeller 1 coincide with each other, air is sucked from the lower surface opening 23 through the space 22 inside the fan common frame 12.
[0016]
This flow of air leads the air heated on the surface of the tube 11 of the fluorescent lamp from the several suction holes 1 of the reflection plate 19 to the internal space 22 of the common fan base 12 and is attached to the internal space 22. The heat generated by the fluorescent lamp ballast 26 is also absorbed, and the temperature is increased to reach the fin tube heat exchanger 13 via the impeller 1 of the radiant blower 4, where it is cooled. The heat is not directly dissipated into the room, but is cooled directly.It does not become a sensible heat load in the room, and the amount of air for cooling the room can be reduced by that much. Since the temperature of the air can be raised to about 40 ° C. regardless of the room temperature, the effective temperature difference of the fin tube heat exchanger 13 is increased, and the heat exchange performance is improved.
[0017]
Fan coil unit lighting power of about 36W / m 2 of recent office of this embodiment, in view of the circumstances in which the air conditioning load is generally approaching 180 W / m 2, the sensible cooling capacity is 200 watts, the ceiling Huai 10 Assuming that the air temperature of 26 ° C. is 47%, the specific volume is 0.85 m 3 / kg, the specific heat is 0.24 kcal / kg, and the outlet temperature of the heat exchanger is 23.5 ° C., the calorific value from the lighting equipment and ballast surface When 40 watts are conventionally dissipated into the room, the amount of air required for cooling the room is calculated by the following equation: 200 W × 0.86 W / kcal / h / (26-23.5) ° C. ÷ 0.24 kcal / kg · ℃ × 0.86m 3 / kg = 246m 3 / h and becomes necessary air volume of the heat generation of 40 watts to the chamber if it is cooled is absorbed directly 246 × (200-40) ÷ 200 = and 197m 3 / h Ri, (246-197) /246=0.2, that is, 20% of the air volume savings.
[0018]
Since the temperature of the air for cooling the heat generated by the fluorescent lamp can be allowed to rise to 40 ° C., 40 × 0.86 ÷ (40−26) ÷ 0.24 × 0.86 = 8.8 m 3 / h, Since the sum of the amount of air from the ceiling 10 and the above-mentioned 8.8 m 3 / h is 197 m 3 , the air temperature at the inlet of the heat exchanger is calculated by proportional distribution {(197−8.8) × 26 + 8.8 × 40}. 197 = 26.6 ° C.
[0019]
In the present embodiment, the inlet chilled water temperature of the fin tube heat exchanger 13 is planned to be 22.5 ° C and the outlet chilled water temperature is set to 24 ° C. The logarithmic mean temperature difference in the exchanger 14 is 1.4 ° C. between 26-24 = 2 ° C. and 23.5-22.5 = 1 ° C. In the case of direct cooling according to the present embodiment, the logarithmic mean temperature difference is It becomes 1.67 ° C between 26.6-24 = 2.6 ° C and 23.5-22.5 = 1 ° C, and the performance of the heat exchanger is improved by about 20%.
[0020]
The air conditioner according to the present embodiment is intended for use in an air conditioning system for dehumidifying outside air separately introduced into a room to a low temperature and processing a latent heat load in the room. If the density of the occupants increases abnormally due to a gathering or the like, the possibility that the humidity increases and the dew condensation on the fin tube heat exchanger 14 cannot be denied. For this purpose, a drain pan 18 is provided below the lowermost end of the inclined fins of the fin tube heat exchanger 13. However, the accumulation of drain is regarded as an abnormal situation, and the moisture sensor 27 detects the drain to detect an abnormal alarm. Was issued and the blower was stopped. In the figure, reference numeral 28 denotes a ceiling plate.
[0021]
FIG. 2 is a view showing a case where the radial blower 4 of the embodiment is replaced with an axial blower 29 in order to improve aerodynamic performance, and the motor itself has a ventilation cooling function to form a ventilation type motor 30; The air is sucked from the opening 32, and the air that has absorbed the heat generated from the surface of the lighting fixture by using the wind force is used to cool the motor through the surrounding opening 34 directly below the motor upper bracket 33. An embodiment will be described in which the same effect as in the case of the radiant blower 4 can be obtained by discharging to the heat exchanger upstream side.
【The invention's effect】
Since the present invention is configured as shown in the embodiment, all the functions of the fan coil unit are contained within the plane area of the conventional lighting fixture, eliminating the planar contact between the air conditioner and the lighting fixture on the ceiling, They have been improved so that they can be arranged evenly with each other. Furthermore, by directly absorbing the heat generated from the surface of the fluorescent lighting equipment, the sensible heat load in the room was reduced, and the air volume was reduced by 20% and the performance of the heat exchanger was improved by 20%.
