Description
本考案は、特に、冷水管、電動冷水三方弁、小型ファンコイルユニット、室内設定表示制御器、二つの風温度センサ及び中央制御ユニットを包括してコンピュータに接続することからなる、複数の中央制御ユニットを有して冷水空調を制御する小型ファンコイルユニットシステムに関するものである。 In particular, the present invention includes a plurality of central control units comprising a chilled water pipe, an electric chilled water three-way valve, a small fan coil unit, a room setting display controller, two wind temperature sensors and a central control unit connected to a computer. The present invention relates to a small fan coil unit system that has a unit and controls cold water air conditioning.
図１のように、通常、従来の中央冷水空調の小型ファンコイルユニットシステムは、往温度７℃、還温度１２℃の冷水管路、室内型温度及び風速制御器Ｓ１、電動冷水三方弁Ｖ１及び小型ファンコイルユニット１によって主な循環運動システムを構成し、そのうち、小型ファンコイルユニット１は、ファンＦ１及びモータＭ１を内設し、その作動の原理は、７℃の冷水が小型ファンコイルユニットの熱交換器螺旋管Ｃ１に入り込み、循環流路上の熱負荷気流を冷却することで温度を下げ、室内型温度及び風速制御器Ｓ１が室内温度を感知し、設定した温度値に基づいて冷水管路上に設置した電動冷水三方弁Ｖ１を制御し、熱交換器螺旋管Ｃ１に流れ込む冷水流量を調節することで、熱負荷気流の冷却という目的を達成し、これにより室内の空調に設定した温度値を制御することにある。 As shown in FIG. 1, the conventional small fan coil unit system of the central chilled water air conditioner usually has a chilled water pipe having a forward temperature of 7 ° C. and a return temperature of 12 ° C., an indoor temperature and wind speed controller S1, an electric chilled water three-way valve V1 The small fan coil unit 1 constitutes a main circulation motion system. Among them, the small fan coil unit 1 includes a fan F1 and a motor M1, and the principle of operation thereof is that cold water of 7 ° C. is used for the small fan coil unit. The temperature is lowered by entering the heat exchanger spiral pipe C1 and cooling the heat load airflow on the circulation flow path, the indoor temperature and wind speed controller S1 senses the room temperature, and on the cold water pipe line based on the set temperature value The purpose of cooling the heat load airflow is achieved by controlling the electric cold water three-way valve V1 installed in the air and adjusting the flow rate of the cold water flowing into the heat exchanger spiral tube C1, thereby improving the indoor air It is to control the temperature value set on.
また、図２のように、その他の中央冷水空調の小型ファンコイルユニットシステムは、室内型温度及び風速制御器Ｓ２、電動冷水三方弁Ｖ２、小型ファンコイルユニット２、水温センサＴ１、Ｔ２及び水流量センサＦによって構成し、小型ファンコイルユニット２は、熱交換器螺旋管Ｃ２、ファンＦ２及びモータＭ２を内設し、現在では、循環運動システムは、商業オフィスビルの空調システムとして主流となっているが、オフィスを借り受けた借用者の空調の使用量を管理するという需要から、現在、ＢＴＵ空調計量器３を併設することが主流となっており、このＢＴＵ空調計量器３は、水温センサＴ１、Ｔ２、水流量センサＦ及び計量器内にある演算ユニットによって構成し、その作動の原理は、水温センサＴ１、Ｔ２が冷水管に往還する水の温度値を感知し、水流量センサＦが冷水管の流量値を感知し、この温度値と流量値とを計量器内にある演算ユニットに介して処理すると、借用者の空調使用量が得られ、これにより借用者に空調を使用した分の費用を徴収することにある。 In addition, as shown in FIG. 2, the other small fan coil unit system of the central cold water air conditioner includes an indoor type temperature and wind speed controller S2, an electric cold water three-way valve V2, a small fan coil unit 2, water temperature sensors T1 and T2, and a water flow rate. The small fan coil unit 2 includes a heat exchanger spiral tube C2, a fan F2, and a motor M2. The circulation motion system is currently mainstream as an air conditioning system for commercial office buildings. However, due to the demand for managing the amount of air conditioning used by borrowers borrowed from offices, it is now mainstream to install a BTU air conditioning meter 3, which is equipped with a water temperature sensor T1, It is composed of T2, the water flow sensor F and the arithmetic unit in the meter. The principle of operation is that the water temperature sensors T1 and T2 return to the cold water pipe. When the temperature value of water is sensed and the water flow rate sensor F senses the flow rate value of the cold water pipe and processes this temperature value and flow rate value through the arithmetic unit in the measuring instrument, the air conditioning usage amount of the borrower is reduced. This is to collect the cost of using air conditioning for the borrower.
上述したＢＴＵ空調計量器の応用原理は合理的ではあるが、実務的使用経験上、いくつかの課題が存在している。第一に、水流量センサＦの測定には極めて大きな誤差があり、且つその精度の校正や検査は容易ではないため、管理側と借用者側との間で空調費用に関して争議が多々発生しており、第二に、各冷水管配線が冷水を複数の小型ファンコイルユニット２に供給しており、冷水管上に固定しているＢＴＵ空調計量器３は、新旧の借用者の入れ替えにより借用面積や間取りが変更され、小型ファンコイルユニット２もこれに合わせて配置を調整すること等があるため、ＢＴＵ空調計量器３が当初設定した面積や間取りと異なり、空調費用の計算に混乱が生じ、当初の使用目的を果たせなくなってしまう。 Although the application principle of the above-mentioned BTU air-conditioning measuring instrument is reasonable, there are some problems in practical use experience. First, since there is an extremely large error in the measurement of the water flow sensor F, and calibration and inspection of its accuracy is not easy, there are many disputes regarding the air conditioning costs between the management side and the borrower side. Secondly, each cold water pipe wiring supplies cold water to a plurality of small fan coil units 2, and the BTU air conditioner 3 fixed on the cold water pipe can be borrowed by replacing old and new borrowers. The layout of the small fan coil unit 2 may be adjusted to match the layout of the small fan coil unit 2, so the BTU air conditioner 3 will be confused in the calculation of air conditioning costs, unlike the area and floor plan initially set. The original purpose of use cannot be achieved.
本考案の主要な目的は、空調計量の誤差が少なく、空調費用の計算に混乱が生じ難い小型ファンコイルユニットシステムを提供することにある。 The main object of the present invention is to provide a small fan coil unit system that has little error in air conditioning measurement and is less likely to cause confusion in the calculation of air conditioning costs.
上述した目的を達成するため、本考案は、冷水管、電動冷水三方弁、ファンコイルユニット（Ｆａｎ Ｃｏｉｌ Ｕｎｉｔ，Ｆ．Ｃ．Ｕ）、室内設定表示制御器、二つの風温度センサ及び中央制御ユニット（Ｃｏｎｔｒｏｌ Ｕｎｉｔ）を包括して構成する、複数の中央制御ユニットを有して冷水空調を制御する小型ファンコイルユニットシステムであって、前記中央制御ユニットは、前記室内設定表示制御器、前記電動冷水三方弁及びコンピュータに接続し、そのうち、前記中央制御ユニットは、前記小型ファンコイルユニットが出入する風の温度を感知するための風温度センサを左右に接続しており、本考案に係る前記中央制御ユニットと前記室内設定表示制御器との作動原理は、以下のとおりである。前記中央制御ユニットにある風温度センサは、前記小型ファンコイルユニットに入り込む風の温度を感知し、前記室内設定表示制御器の室温設定値と比較し、比較値の高低差に基づき、前記小型ファンコイルユニットの回転速度、即ち風量を自動的に調節し、前記風温度センサが感知した温度が前記室内設定表示制御器の室温設定値より低い場合、一定時間内において、前記中央制御ユニットはファンのモータの回転速度を減速、即ち風量を減少させて冷却効果を低減し、最終的に、前記ファンの前記モータが最低回転速度まで調節、即ち最低限の快適な循環風量に維持された時、前記風温度センサが感知した温度が依然として前記室内設定表示制御器の室温設定値より低い場合、前記中央制御ユニットは前記電動冷水三方弁を調節し始め、冷水流量の大きさを制御することで、前記風温度センサが感知する気流温度は、前記室内設定表示制御器の室温設定値に徐々に近接することができ、これとは反対に、感知した気流温度が前記室内設定表示制御器の室温設定値より高い場合、前記中央制御ユニットの制御論理から、上述した作動とは逆に作動することである。 In order to achieve the above-mentioned object, the present invention includes a cold water pipe, an electric cold water three-way valve, a fan coil unit (Fan Coil Unit, FC), an indoor setting display controller, two wind temperature sensors, and a central control unit. (Control Unit) is a small fan coil unit system having a plurality of central control units to control cold water air conditioning, wherein the central control unit includes the indoor setting display controller, the electric cold water Connected to a three-way valve and a computer, of which the central control unit is connected to right and left wind temperature sensors for sensing the temperature of the wind entering and exiting the small fan coil unit, and the central control according to the present invention The operation principle of the unit and the indoor setting display controller is as follows. The wind temperature sensor in the central control unit senses the temperature of the wind entering the small fan coil unit, compares it with the room temperature setting value of the indoor setting display controller, and based on the difference in level of the comparison value, the small fan When the rotational speed of the coil unit, that is, the air volume is automatically adjusted and the temperature sensed by the wind temperature sensor is lower than the room temperature set value of the indoor setting display controller, the central control unit When the motor speed of the fan is adjusted to the minimum rotational speed, i.e., maintained at the minimum comfortable circulating airflow, the motor speed of the fan is reduced, i.e., the airflow is reduced to reduce the cooling effect. If the temperature sensed by the wind temperature sensor is still lower than the room setting value of the indoor setting display controller, the central control unit starts to adjust the electric cold water three-way valve, By controlling the magnitude of the water flow rate, the airflow temperature sensed by the wind temperature sensor can gradually approach the room temperature setting value of the indoor setting display controller. When the temperature is higher than the room temperature setting value of the indoor setting display controller, the control logic of the central control unit operates opposite to the above-described operation.
本考案に係る、複数の中央制御ユニットを有して冷水空調を制御する小型ファンコイルユニットシステムの制御論理は、従来の中央冷水空調の小型ファンコイルユニットシステムの制御効果を完全に満たすだけでなく、以下のような利点を有する。
第一に、本考案は、水温温度差及び水流量を利用して相乗するＢＴＵ空調計量器で空調使用量を測定する上述した中央冷水空調の小型ファンコイルユニットシステムとは異なり、出入する前記小型ファンコイルユニットの風の温度差値と、前記中央制御ユニットに内設するモータ回転速度及びファン風量の対照値ファームウェアによって測定された前記ファンの前記モータの回転速度値とを利用し、前記中央制御ユニットを介して空調熱負荷値を算出した上で、この前記空調熱負荷値に、前記中央制御ユニットに記録されている前記電動冷水三方弁の開通時間を相乗することで、単体の前記小型ファンコイルユニットの空調使用量を精確に算出することができる。
第二に、本考案は、前記中央制御ユニットが各前記小型ファンコイルユニットに配置していることから、新規の借用者によって借用面積や間取りが異なったとしても、前記コンピュータ上でどの前記小型ファンコイルユニットがこの新規の借用者に関連するかを改めて設定することで、この新規の借用者の空調使用量データを得ることができ、従来のＢＴＵ空調計量器のように、新旧の借用者間で使用する小型ファンコイルユニットの数が異なるため空調使用量が計算できないという問題は発生しない。
第三に、本考案は、前記電動冷水三方弁が前記中央制御ユニットから開通する指令を受けた時、前記小型ファンコイルユニットに出入する風の温度差を利用して前記電動冷水三方弁が故障したか否かを判断し、もし故障だった場合は、前記中央制御ユニットから前記コンピュータに向けて異常警報通知を発信している。
第四に、本考案は、前記中央制御ユニットにモータ回転速度及びファン風量の対照値ファームウェアを内設しており、モータのある回転速度における稼動電流値がファームウェアで既定する電流値より低い場合、前記小型ファンコイルユニットの循環風量に異常が発生していると判断することもでき、その原因はフィルタの目詰まり等である可能性があり、このような異常もまた同じように、前記中央制御ユニットから前記コンピュータに向けて異常警報通知を発信している。
The control logic of a small fan coil unit system having a plurality of central control units and controlling chilled water air conditioning according to the present invention not only completely satisfies the control effect of the conventional small fan coil unit system of central chilled water air conditioning. Has the following advantages.
First, the present invention is different from the above-mentioned small fan coil unit system of central cold water air conditioning that measures air conditioning usage with a BTU air conditioning meter that synergizes using water temperature and temperature difference and water flow rate, and the small size of the small ingress and egress The central control unit uses the temperature difference value of the fan coil unit and the motor rotational speed value of the fan measured by the firmware of the motor rotational speed and the fan air volume installed in the central control unit. After calculating the air conditioning heat load value via the unit, the air conditioning heat load value is combined with the opening time of the electric cold water three-way valve recorded in the central control unit, so that the single small fan The air conditioning usage of the coil unit can be accurately calculated.
Secondly, according to the present invention, since the central control unit is arranged in each small fan coil unit, even if the borrowed area or the floor plan differs depending on the new borrower, which small fan is used on the computer. By setting again whether the coil unit is related to this new tenant, it is possible to obtain the air-conditioning usage data of this new tenant, and between the old and new tenants like the conventional BTU air conditioner. There is no problem that the amount of air conditioning used cannot be calculated because the number of small fan coil units used is different.
Third, when the electric chilled water three-way valve receives a command to open from the central control unit, the electric chilled water three-way valve breaks down using the temperature difference of the wind entering and exiting the small fan coil unit. If there is a failure, the central control unit sends an abnormality alarm notification to the computer.
Fourthly, according to the present invention, the central control unit is provided with a firmware for comparing the motor rotational speed and the fan air volume, and when the operating current value at a certain rotational speed of the motor is lower than the current value defined by the firmware, It can also be determined that an abnormality has occurred in the circulating air volume of the small fan coil unit, and the cause may be clogging of the filter, and such an abnormality is also the same as the central control. An abnormal alarm notification is transmitted from the unit to the computer.
本考案は、複数の中央制御ユニットを有して冷水空調を制御する小型ファンコイルユニットシステム１’であって、図３のように、往温度７℃、還温度１２℃の冷水管Ｐと、電動冷水三方弁Ｖ３と、小型ファンコイルユニット３と、室内設定表示制御器Ｓ３と、二つの風温度センサＴ１１、Ｔ１２と、中央制御ユニットＡ１とを包括して構成し、そのうち、前記冷水管Ｐは、熱交換器螺旋管に接続してその右側にフィルタｆを設置しており、その特徴は、前記中央制御ユニットＡ１が前記室内設定表示制御器Ｓ３と、前記電動冷水三方弁Ｖ３と、前記小型ファンコイルユニット３と、コンピュータＢと接続し、そのうち、前記小型ファンコイルユニット３の往温度、即ち感知温度Ｔ及び還温度Ｔ１’を感知するため、前記中央制御ユニットＡ１の左側に前記風温度センサＴ１１、右側に前記風温度センサＴ１２を接続している。 The present invention is a small fan coil unit system 1 ′ having a plurality of central control units to control cold water air conditioning, and as shown in FIG. 3, a cold water pipe P having a forward temperature of 7 ° C. and a return temperature of 12 ° C., The electric cold water three-way valve V3, the small fan coil unit 3, the indoor setting display controller S3, the two wind temperature sensors T11 and T12, and the central control unit A1 are configured to include the cold water pipe P. Is connected to a heat exchanger spiral tube and a filter f is installed on the right side of the heat exchanger. The central control unit A1 has the indoor setting display controller S3, the electric cold water three-way valve V3, The small fan coil unit 3 is connected to the computer B. Among them, the central control unit A is used to sense the forward temperature of the small fan coil unit 3, that is, the sensing temperature T and the return temperature T1 ′. The air temperature sensor T11 to the left of, connecting said air temperature sensor T12 on the right.
本考案に係る前記中央制御ユニットＡ１と前記室内設定表示制御器Ｓ３との作動手順は以下のとおりである。前記中央制御ユニットＡ１の前記風温度センサＴ１１は、まず前記小型ファンコイルユニット３に入り込む温度を感知して前記室内設定表示制御器の室温設定値と比較し、比較値の高低差に基づき、前記小型ファンコイルユニット３にあるファンＦ３のモータＭ３の回転速度Ｍ１’及び風量Ｗ１を自動的に調節し、なお、これを高速Ｈ、中速Ｍ及び低速Ｌの三段階に分けることができ、また、比較値と前記電動冷水三方弁Ｖ３の開通時間ＴＥは、空調使用量を算出するために用いられている。 The operation procedure of the central control unit A1 and the indoor setting display controller S3 according to the present invention is as follows. The wind temperature sensor T11 of the central control unit A1 first detects the temperature entering the small fan coil unit 3 and compares it with the room temperature setting value of the indoor setting display controller, and based on the difference in level of the comparison value, The rotational speed M1 ′ and the air volume W1 of the motor M3 of the fan F3 in the small fan coil unit 3 are automatically adjusted, and this can be divided into three stages of high speed H, medium speed M and low speed L. The comparison value and the opening time TE of the electric cold water three-way valve V3 are used for calculating the amount of air conditioning used.
前記風温度センサＴ１１が感知した感知温度Ｔが前記室内設定表示制御器Ｓ３の室温設定値ＲＴ１より低い場合、一定時間内において、前記中央制御ユニットＡ１はファンＦ３のモータＭ３の回転速度を減速、即ち風量を減少させて冷却効果を低減し、最終的に、前記ファンＦ３の前記モータＭ３が低速Ｌまで調節、即ち最低限の快適な循環風量に維持された時、前記風温度センサＴ１１が感知した感知温度Ｔが依然として前記室内設定表示制御器Ｓ３の室温設定値ＲＴ１より低い場合、前記中央制御ユニットＡ１は前記電動冷水三方弁Ｖ３を調節し始め、冷水流量の大きさを制御することで、前記風温度センサＴ１１が感知する感知温度Ｔは、前記室内設定表示制御器Ｓ３の室温設定値ＲＴ１に徐々に近接することができ、これとは反対に、前記風温度センサＴ１１が感知した感知温度Ｔが前記室内設定表示制御器Ｓ３の室温設定値ＲＴ１より高い場合、前記中央制御ユニットＡ１の制御論理から、上述した作動とは逆に作動し、一定時間において、前記中央制御ユニットＡ１はファンＦ３のモータＭ３の回転速度を増速、即ち風量を増加させて冷却効果を増強し、最終的に、前記ファンＦ３の前記モータＭ３を高速Ｈまで調節している。 When the detected temperature T sensed by the wind temperature sensor T11 is lower than the room temperature setting value RT1 of the indoor setting display controller S3, the central control unit A1 decelerates the rotational speed of the motor M3 of the fan F3 within a certain time, That is, the cooling effect is reduced by reducing the air volume, and finally, the wind temperature sensor T11 senses when the motor M3 of the fan F3 is adjusted to the low speed L, that is, the minimum comfortable circulating air volume is maintained. When the detected temperature T is still lower than the room temperature setting value RT1 of the indoor setting display controller S3, the central control unit A1 starts to adjust the electric cold water three-way valve V3, and controls the size of the cold water flow rate. The sensed temperature T sensed by the wind temperature sensor T11 can gradually approach the room temperature setting value RT1 of the indoor setting display controller S3, on the contrary. When the sensed temperature T sensed by the wind temperature sensor T11 is higher than the room temperature setting value RT1 of the indoor setting display controller S3, the control logic of the central control unit A1 operates in reverse to the above-described operation for a certain period of time. The central control unit A1 increases the rotational speed of the motor M3 of the fan F3, that is, increases the air volume to enhance the cooling effect, and finally adjusts the motor M3 of the fan F3 to the high speed H. Yes.
