例えば、塗装工場などにおいて塗装の品質を安定して確保するためには、工場室内の温度だけではなく湿度の管理が重要となる。すなわち、工場室内の露点温度の制御が重要となる。   For example, in order to stably ensure the quality of painting in a painting factory or the like, it is important to manage not only the temperature in the factory room but also the humidity. That is, it is important to control the dew point temperature in the factory room.

しかしながら、上記特許文献1のように、室内温度だけを測定してローターの回転数を制御する回転式全熱交換器では、制御目標である露点温度(以下「目標露点温度」という)との乖離がある現状の室内露点温度を、目標露点温度に近づけて収束させることができない。   However, as in the above-mentioned Patent Document 1, in a rotary total heat exchanger that measures only the room temperature and controls the rotational speed of the rotor, the deviation from the dew point temperature (hereinafter referred to as “target dew point temperature”) that is the control target. The current indoor dew point temperature cannot be converged close to the target dew point temperature.

本発明は、上記課題を鑑みてなされたものであり、室内露点温度を目標露点温度に近づけて収束させることができる、回転式全熱交換器に用いられる制御装置を提供することを目的とする。   This invention is made | formed in view of the said subject, and it aims at providing the control apparatus used for a rotary total heat exchanger which can converge indoor dew point temperature close | similar to target dew point temperature. .

上記課題を解決するために、本発明の一態様は、回転式全熱交換器のローターの回転数を制御する制御装置であって、室内に設置された露点温度計から室内露点温度を取得する取得部と、予め設定された目標露点温度と室内露点温度との差に基づくPID演算を実施し、その差が大きいほどローターの回転数が大きくなる制御量を算出する演算部と、制御量に従った回転数でローターを駆動する駆動部とを備える、ことを特徴とする。   In order to solve the above problems, one aspect of the present invention is a control device that controls the number of rotations of a rotor of a rotary total heat exchanger, and acquires an indoor dew point temperature from a dew point thermometer installed indoors. An acquisition unit, a calculation unit that performs a PID calculation based on a difference between a preset target dew point temperature and an indoor dew point temperature, and calculates a control amount that increases the rotational speed of the rotor as the difference increases, and a control amount And a drive unit that drives the rotor at the corresponding rotational speed.

この本発明の制御装置では、パラメータとして露点温度を用いて、目標露点温度と実測の室内露点温度との差に基づいたPID演算の結果に従って、2つの露点温度差が大きいほどローターの回転数が大きくなるように制御する。これにより、簡単に室内露点温度を目標露点温度に近づけて収束させることができる。   In the control device of the present invention, using the dew point temperature as a parameter, according to the result of the PID calculation based on the difference between the target dew point temperature and the measured indoor dew point temperature, the larger the two dew point temperature difference, the higher the rotor speed.

以上述べたように、本発明の回転式全熱交換器に用いられる制御装置によれば、露点温度に基づいて既存の回転式全熱交換器に対してローターの回転数を増減制御するだけで、簡単に室内露点温度を目標露点温度に近づけて収束させることができる。   As described above, according to the control device used in the rotary total heat exchanger of the present invention, it is only necessary to increase / decrease the rotational speed of the rotor with respect to the existing rotary total heat exchanger based on the dew point temperature.

[概要]
本発明の回転式全熱交換器に用いられる制御装置は、パラメータとして露点温度を用いる。予め定めた目標露点温度と実測した室内露点温度との差に基づいたPID演算を実施して、2つの露点温度差が大きいほどローターの回転数が大きくなるように制御する。これにより、簡単に室内露点温度を目標露点温度に近づけて収束させることができる。
[Overview]
The control device used in the rotary total heat exchanger of the present invention uses the dew point temperature as a parameter. PID calculation based on a difference between a predetermined target dew point temperature and an actually measured indoor dew point temperature is performed, and control is performed so that the number of rotations of the rotor increases as the difference between the two dew point temperatures increases. Thereby, the indoor dew point temperature can be easily brought close to the target dew point temperature and converged.

[回転式全熱交換器の構造]
図1は、本発明が提供する制御装置を用いることが可能な回転式全熱交換器10の構造例を説明するための概略斜視図である。図1に示す回転式全熱交換器10は、ケーシング11の内部に、ローター12、回転モータ13、および駆動ベルト14を、備えて構成されている。なお、図1においては、ケーシング11の一部を切り欠いて内部が見えるようにしている。
[Structure of rotary total heat exchanger]
FIG. 1 is a schematic perspective view for explaining a structural example of a rotary total heat exchanger 10 capable of using a control device provided by the present invention. A rotary total heat exchanger 10 shown in FIG. 1 includes a rotor 12, a rotary motor 13, and a drive belt 14 inside a casing 11. In FIG. 1, a part of the casing 11 is cut away so that the inside can be seen.

ケーシング11は、略直方体の形状をしており、対向する2つの面に円形状の開口部をそれぞれ有している。2つの開口部は、セパレーター11Sによって第1領域および第2領域の2つにそれぞれ仕切られている。   The casing 11 has a substantially rectangular parallelepiped shape, and has circular openings on two opposing surfaces. The two openings are divided into two areas, a first area and a second area, by a separator 11S.

ローター12は、円盤形状をしており、円盤の中心軸を回転軸として、円盤面と開口部とが平行になる配置で、ケーシング11に回転可能に支持されている。このローター12は、回転軸方向に通気性を有するハニカム構造やコルゲート構造などを持つ熱交換素子を有している。   The rotor 12 has a disk shape and is rotatably supported by the casing 11 in such a manner that the disk surface and the opening are parallel with the central axis of the disk as a rotation axis. The rotor 12 includes a heat exchange element having a honeycomb structure or a corrugated structure having air permeability in the rotation axis direction.

回転モータ13は、後述する制御装置20から指示される駆動信号に従って、所定の回転数で回転を行う。ローター12には、駆動ベルト14が掛け回されており、回転モータ13が発生した回転力を駆動ベルト14を介してローター12に伝え、ローター12を回転させる。   The rotation motor 13 rotates at a predetermined rotation number in accordance with a drive signal instructed from the control device 20 described later. A driving belt 14 is wound around the rotor 12, and the rotational force generated by the rotary motor 13 is transmitted to the rotor 12 via the driving belt 14 to rotate the rotor 12.

[回転式全熱交換器の動作]
回転式全熱交換器10は、例えば、室内と屋外とを区切る場所などに配置される。ローター12は、その一部の箇所に着目すると、回転モータ13および駆動ベルト14によって図1に示した矢印方向に回転し、セパレーター11Sによって仕切られた第1領域と第2領域とを循環して通過することとなる。
[Operation of rotary total heat exchanger]
The rotary total heat exchanger 10 is disposed, for example, at a place that separates the room and the outdoors. Focusing on a part of the rotor 12, the rotor 12 is rotated in the direction of the arrow shown in FIG. 1 by the rotary motor 13 and the drive belt 14, and circulates between the first region and the second region partitioned by the separator 11S. Will pass.

室内に向けられた開口部の第1領域からは、室内の空気が「還気」として取り込まれる。第1領域から取り込まれた還気は、全熱(温度、湿度)の一部がローター12で回収(蓄熱)された後、屋外に向けられた開口部の第1領域から「排気」となって屋外に排出される。   Indoor air is taken in as “return air” from the first region of the opening directed to the room. The return air taken in from the first region becomes “exhaust” from the first region of the opening directed to the outside after a part of the total heat (temperature, humidity) is recovered (heat storage) by the rotor 12. Are discharged outdoors.

一方、屋外に向けられた開口部の第2領域からは、屋外の空気が「外気」として取り込まれる。第2領域から取り込まれた外気は、還気から回収(蓄熱)された全熱(温度、湿度)をローター12から受け取った後、室内に向けられた開口部の第2領域から「給気」として室内に導入される。   On the other hand, outdoor air is taken in as “outside air” from the second region of the opening directed to the outdoors. The outside air taken in from the second region receives the total heat (temperature, humidity) recovered from the return air (heat storage) from the rotor 12 and then “air supply” from the second region of the opening directed indoors. As introduced into the room.

このように、回転式全熱交換器10は、還気の全熱(温度、湿度)と外気の全熱(温度、湿度)とを交換させて、給気の全熱(温度、湿度)を作り出す動作を行う。還気と外気との間で行われる全熱(温度、湿度)の交換は、ローター12の回転数が大きくなると効率が上昇し、ローター12の回転数が小さくなると効率が下降する。   In this way, the rotary total heat exchanger 10 exchanges the total heat (temperature, humidity) of the return air and the total heat (temperature, humidity) of the outside air, thereby changing the total heat (temperature, humidity) of the supply air. Perform the action to create. The exchange of total heat (temperature and humidity) performed between the return air and the outside air increases in efficiency as the rotor 12 rotates, and decreases in efficiency as the rotor 12 decreases.

[制御装置の構成]
図2は、本発明の一実施形態に係る回転式全熱交換器10に用いられる制御装置20の構成を示す図である。図2に示した制御装置20は、取得部21と、演算部22と、駆動部23と、を備えている。この制御装置20は、図示するように室内側に設けられてもよいし、屋外側に設けられてもよい。
[Configuration of control device]
FIG. 2 is a diagram illustrating a configuration of the control device 20 used in the rotary total heat exchanger 10 according to the embodiment of the present invention. The control device 20 illustrated in FIG. 2 includes an acquisition unit 21, a calculation unit 22, and a drive unit 23. The control device 20 may be provided on the indoor side as illustrated, or may be provided on the outdoor side.

取得部21は、室内に設置された所定の露点温度計30から現状の露点温度(以下「室内露点温度Tdp」という)を取得する。露点温度計30は、設置された室内環境(温度および湿度)に基づいた露点温度を検知する素子であり、例えば露点温度センサや温湿度センサである。露点温度計30では、例えば室内露点温度Tdpとして「−20〜+60℃」の範囲の値が検知される。   The acquisition unit 21 acquires the current dew point temperature (hereinafter referred to as “indoor dew point temperature Tdp”) from a predetermined dew point thermometer 30 installed indoors. The dew point thermometer 30 is an element that detects the dew point temperature based on the installed indoor environment (temperature and humidity), and is, for example, a dew point temperature sensor or a temperature / humidity sensor. In the dew point thermometer 30, for example, a value in the range of “−20 to + 60 ° C.” is detected as the indoor dew point temperature Tdp.

演算部22には、制御目標である室内露点温度(以下「目標露点温度STdp」という)が、予めユーザなどによって任意に設定されている。具体的には、目標露点温度STdpは、ユーザなどによって設定された温度および湿度から算出される。演算部22は、取得部21によって取得された室内露点温度Tdpを入力し、予め設定された目標露点温度STdpと室内露点温度Tdpとの差(偏差)に基づくPID演算を実施する。   An indoor dew point temperature (hereinafter referred to as “target dew point temperature STdp”), which is a control target, is arbitrarily set in the computing unit 22 by a user or the like in advance. Specifically, the target dew point temperature STdp is calculated from the temperature and humidity set by the user or the like. The calculation unit 22 inputs the indoor dew point temperature Tdp acquired by the acquisition unit 21, and performs PID calculation based on a difference (deviation) between the preset target dew point temperature STdp and the indoor dew point temperature Tdp.

この演算部22は、PID演算によって、目標露点温度STdpと室内露点温度Tdpとの差(絶対値)が大きいほどローター12の回転数を大きくすることができる指示を回転式全熱交換器10に与えることができる、所定の制御量OPを算出する。より具体的には、演算部22は、制御量OPとして、ローター12の回転数を最小(または停止)にするように指示する「0%」から、ローター12の回転数を最大(能力または規格)にするように指示する「100%」の範囲の値を、目標露点温度STdpと室内露点温度Tdpとの差に応じて連続的または離散的に算出する。   The calculation unit 22 gives an instruction to the rotary total heat exchanger 10 to increase the rotational speed of the rotor 12 as the difference (absolute value) between the target dew point temperature STdp and the indoor dew point temperature Tdp increases by PID calculation. A predetermined control amount OP that can be given is calculated. More specifically, the calculation unit 22 sets the rotation speed of the rotor 12 to the maximum (capacity or standard) from “0%” which instructs to minimize (or stop) the rotation speed of the rotor 12 as the control amount OP. ) Is calculated continuously or discretely according to the difference between the target dew point temperature STdp and the indoor dew point temperature Tdp.

離散的な一例としては、目標露点温度STdpと室内露点温度Tdpとの差(絶対値)が、ゼロであれば「0%」の値が、ゼロを超えて第1閾値未満であれば「+25%」の値が、第1閾値以上第2閾値未満であれば「+50%」の値が、第2閾値以上第3閾値未満であれば「+75%」の値が、第3閾値以上であれば「+100%」の値が、演算部22から制御量OPとして算出される。   As a discrete example, if the difference (absolute value) between the target dew point temperature STdp and the indoor dew point temperature Tdp is zero, a value of “0%” exceeds zero and is less than the first threshold, and is “+25”. If the value “%” is greater than or equal to the first threshold and less than the second threshold, the value “+ 50%” is greater than or equal to the second threshold and less than the third threshold, and the value “+ 75%” is greater than or equal to the third threshold. For example, a value of “+ 100%” is calculated as the control amount OP from the calculation unit 22.

なお、演算部22では、典型的には、目標露点温度STdpおよび室内露点温度Tdpは、所定の範囲の電流値に変換(例えば「−20〜+60℃」→「4〜20mA」)された後に、PID演算が実行される。   Note that, in the calculation unit 22, the target dew point temperature STdp and the indoor dew point temperature Tdp are typically converted into current values in a predetermined range (for example, “−20 to + 60 ° C.” → “4 to 20 mA”). , PID calculation is executed.

駆動部23は、演算部22によって算出された制御量OPを入力し、その制御量OPを回転式全熱交換器10のローター12を駆動するために必要な駆動信号、より具体的にはローター12の回転数を調整することができる信号、に変換する。典型的には、駆動部23は、電力変換を行うインバータ装置であり、制御量OPに従った回転数でローター12を駆動させるために、制御量OPを回転数に対応したインバータ周波数fに変換する。例えば、駆動部23は、「0〜+100%」範囲の制御量OPをローター12の回転数を定める「0〜60Hz」範囲のインバータ周波数fに変換する。   The drive unit 23 receives the control amount OP calculated by the calculation unit 22, and uses the control amount OP as a drive signal necessary for driving the rotor 12 of the rotary total heat exchanger 10, more specifically, the rotor. 12 is converted into a signal that can adjust the number of rotations. Typically, the drive unit 23 is an inverter device that performs power conversion, and converts the control amount OP into an inverter frequency f corresponding to the rotation number in order to drive the rotor 12 at the rotation number according to the control amount OP. To do. For example, the drive unit 23 converts the control amount OP in the “0 to + 100%” range into the inverter frequency f in the “0 to 60 Hz” range that determines the rotation speed of the rotor 12.

例えば、駆動部23は、演算部22から算出された制御量OPが、ローター12の回転数を最小(または停止)にするように指令する「0%」の制御量OPであれば、制御量OPを「0Hz」のインバータ周波数fに変換し、「50%」の制御量OPであれば、制御量OPを「30Hz」のインバータ周波数fに変換し、ローター12の回転数を最大(能力または規格)にするように指令する「100%」の制御量OPであれば、制御量OPを「60Hz」のインバータ周波数fに変換する。   For example, if the control amount OP calculated from the calculation unit 22 is “0%” of the control amount OP that instructs the rotational speed of the rotor 12 to be minimized (or stopped), the drive unit 23 controls the control amount. If OP is converted to an inverter frequency f of “0 Hz” and the control amount OP is “50%”, the control amount OP is converted to an inverter frequency f of “30 Hz” and the rotational speed of the rotor 12 is maximized (capacity or If the control amount OP is “100%” commanded to be standard), the control amount OP is converted to the inverter frequency f of “60 Hz”.

そして、駆動部23は、制御量OPが変換されて得られたインバータ周波数fの信号を回転式全熱交換器10に出力することで、ローター12の回転数を調整する。すなわち、駆動部23は、制御量OPに応じた回転数で回転式全熱交換器10のローター12を駆動することができる。   And the drive part 23 adjusts the rotation speed of the rotor 12 by outputting the signal of the inverter frequency f obtained by converting the control amount OP to the rotary total heat exchanger 10. That is, the drive unit 23 can drive the rotor 12 of the rotary total heat exchanger 10 at a rotation speed corresponding to the control amount OP.

[制御装置が行う制御]
図3は、本発明の一実施形態に係る回転式全熱交換器10に用いられる制御装置20で行われる制御の処理手順を示す図である。図3に示す処理は、回転式全熱交換器10および制御装置20の双方が稼働すると開始される。
[Control performed by controller]
FIG. 3 is a diagram illustrating a control processing procedure performed by the control device 20 used in the rotary total heat exchanger 10 according to the embodiment of the present invention. The process shown in FIG. 3 is started when both the rotary total heat exchanger 10 and the control device 20 are operated.

まず、ステップS31において、取得部21によって、室内に設置された露点温度計30から室内露点温度Tdpが取得される。例えば、「−20〜+60℃」の範囲の値が室内露点温度Tdpとして取得される。   First, in step S31, the acquisition unit 21 acquires the indoor dew point temperature Tdp from the dew point thermometer 30 installed indoors. For example, a value in the range of “−20 to + 60 ° C.” is acquired as the indoor dew point temperature Tdp.

次に、ステップS32において、演算部22によって、取得部21で取得された室内露点温度Tdpと、予め設定された目標露点温度STdpとの差に基づくPID演算が実施され、ローター12の回転数の制御に関わる制御量OPが算出される。   Next, in step S32, the calculation unit 22 performs PID calculation based on the difference between the indoor dew point temperature Tdp acquired by the acquisition unit 21 and a preset target dew point temperature STdp, and the rotational speed of the rotor 12 is calculated. A control amount OP related to the control is calculated.

この制御量OPは、目標露点温度STdpと室内露点温度Tdpとの差が大きくなるほどローター12の回転数を大きくすることができる値である。よって例えば、目標露点温度STdpと室内露点温度Tdpとの差(絶対値)がゼロならば、全熱交換は必要ないため、ローター12の回転数を最小(または停止)にさせる「0%」の値が、制御量OPとして算出される。また、目標露点温度STdpと室内露点温度Tdpとの差(絶対値)があれば、その差の大きさに応じた全熱交換を行うべく、ローター12を必要な回転数にさせるために「+1〜+100%」の範囲いずれかの値が、制御量OPとして算出される。   This control amount OP is a value that can increase the rotational speed of the rotor 12 as the difference between the target dew point temperature STdp and the indoor dew point temperature Tdp increases. Thus, for example, if the difference (absolute value) between the target dew point temperature STdp and the room dew point temperature Tdp is zero, total heat exchange is not necessary, so that the rotation speed of the rotor 12 is “0%” which is minimized (or stopped). A value is calculated as the control amount OP. Further, if there is a difference (absolute value) between the target dew point temperature STdp and the indoor dew point temperature Tdp, “+1” is used in order to make the rotor 12 have a necessary number of revolutions in order to perform total heat exchange according to the magnitude of the difference. Any value in the range of “˜ + 100%” is calculated as the control amount OP.

次に、ステップS33において、駆動部23によって、演算部22で算出された制御量OPが、ローター12を制御量OPに従った回転数で駆動するためのインバータ周波数fに変換される。例えば、「0〜+100%」の範囲の制御量OPが、「0〜60Hz」の範囲のインバータ周波数fに変換される。   Next, in step S33, the control unit OP calculated by the calculation unit 22 is converted into an inverter frequency f for driving the rotor 12 at a rotational speed according to the control amount OP by the drive unit 23. For example, the control amount OP in the range of “0 to + 100%” is converted into the inverter frequency f in the range of “0 to 60 Hz”.

そして、ステップS34において、駆動部23によって変換されたインバータ周波数fの信号が回転式全熱交換器10に出力され、インバータ周波数f(換言すれば制御量OP)に応じた回転数でローター12が駆動される。例えば、「0Hz」のインバータ周波数fで駆動されるローター12は、回転を停止することになって全熱(温度、湿度)の交換率が最小となり、「60Hz」のインバータ周波数fで駆動されるローター12は、最大回転数で回転することになって全熱(温度、湿度)の交換率が最大となる。   In step S34, the signal of the inverter frequency f converted by the drive unit 23 is output to the rotary total heat exchanger 10, and the rotor 12 is rotated at the number of rotations corresponding to the inverter frequency f (in other words, the control amount OP). Driven. For example, the rotor 12 driven at the inverter frequency f of “0 Hz” stops rotating, and the exchange rate of total heat (temperature, humidity) is minimized, and is driven at the inverter frequency f of “60 Hz”. The rotor 12 rotates at the maximum rotation speed, and the exchange rate of total heat (temperature, humidity) is maximized.

この制御により、回転式全熱交換器10における還気と外気との間で行われる全熱(温度、湿度)の交換率を、室内露点温度Tdpを目標露点温度STdpに近づけて収束させる方向に、動的に制御することができる。   By this control, the exchange rate of the total heat (temperature, humidity) performed between the return air and the outside air in the rotary total heat exchanger 10 is converged so that the indoor dew point temperature Tdp approaches the target dew point temperature STdp. Can be controlled dynamically.

[実施形態による作用・効果]
以上のように、本発明の一実施形態に係る回転式全熱交換器10に用いられる制御装置20によれば、パラメータとして露点温度を用いて、目標露点温度STdpと室内露点温度Tdpとの差に基づいたPID演算の結果に従ってローター12の回転数を制御する。
[Operations and effects according to the embodiment]
As described above, according to the control device 20 used in the rotary total heat exchanger 10 according to the embodiment of the present invention, using the dew point temperature as a parameter, the difference between the target dew point temperature STdp and the indoor dew point temperature Tdp. The rotational speed of the rotor 12 is controlled according to the result of the PID calculation based on the above.

この制御では、目標露点温度STdpと室内露点温度Tdpとの差が大きくなるほどローター12の回転数が大きくなるように制御する。つまり、目標露点温度STdpに対する室内露点温度Tdpの乖離が大きければ、ローター12の回転数を大きくして回転式全熱交換器10の全熱(温度、湿度)の交換率を上げて、目標露点温度STdpと室内露点温度Tdpとの差が小さくなるように調整する。逆に、目標露点温度STdpに対する室内露点温度Tdpの乖離が小さければ、ローター12の回転数を小さく回転式全熱交換器10の全熱(温度、湿度)の交換率を下げて、目標露点温度STdpと室内露点温度Tdpとの差が大きくならないように調整する。   In this control, control is performed so that the rotational speed of the rotor 12 increases as the difference between the target dew point temperature STdp and the indoor dew point temperature Tdp increases. That is, if the difference between the indoor dew point temperature Tdp and the target dew point temperature STdp is large, the rotational speed of the rotor 12 is increased to increase the total heat (temperature, humidity) exchange rate of the rotary total heat exchanger 10, and the target dew point is increased. Adjustment is made so that the difference between the temperature STdp and the room dew point temperature Tdp becomes small. On the contrary, if the difference between the indoor dew point temperature Tdp and the target dew point temperature STdp is small, the rotational speed of the rotor 12 is decreased and the total heat (temperature, humidity) exchange rate of the rotary total heat exchanger 10 is decreased. Adjust so that the difference between STdp and room dew point temperature Tdp does not become large.

よって、露点温度に基づいて既存の回転式全熱交換器10に対してローター12の回転数を増減制御するだけで、簡単に室内露点温度Tdpを目標露点温度STdpに近づけて収束させることができる。   Therefore, the indoor dew point temperature Tdp can be easily brought close to the target dew point temperature STdp and converged by simply increasing / decreasing the rotational speed of the rotor 12 with respect to the existing rotary total heat exchanger 10 based on the dew point temperature. .

特に、本実施形態に係る制御装置20では、ローター12の回転数を増減制御するだけでよく、全熱交換のためにヒータや冷水機などの別構成を必要としないため、回転式全熱交換器10を簡素化でき、イニシャルコストを抑えることができる。また、ヒータや冷水機などを使用しないためランニングコストも抑えることができる。   In particular, in the control device 20 according to the present embodiment, it is only necessary to increase / decrease the number of rotations of the rotor 12, and a separate configuration such as a heater or a chiller is not required for total heat exchange. The vessel 10 can be simplified and the initial cost can be suppressed. In addition, since no heater or chiller is used, running costs can be reduced.

また、本実施形態に係る制御装置20が実行する回転式全熱交換器10の制御を、他の空調機器の制御と組み合わせて実施することで、全熱(温度、湿度)の交換率を更に向上させることができ、省エネルギーによる運用を期待できる。   In addition, the control of the rotary total heat exchanger 10 executed by the control device 20 according to the present embodiment is performed in combination with the control of other air conditioning equipment, thereby further increasing the total heat (temperature, humidity) exchange rate. It can be improved and energy-saving operation can be expected.

また、例えば外気露点温度に基づいて制御すると、外気エンタルピラインの熱量を室内エンタルピラインの熱量に合わせる必要がある。しかし、本発明のように室内露点温度に基づく制御であれば、室内エンタルピラインの熱量があればよいので、このときの熱量差がエネルギー低減分となる(図4の矢印を参照)。   For example, if the control is based on the outside air dew point temperature, it is necessary to match the amount of heat of the outside enthalpy line with the amount of heat of the indoor enthalpy line. However, in the case of the control based on the indoor dew point temperature as in the present invention, it is sufficient if there is a heat quantity of the indoor enthalpy line, and the heat quantity difference at this time becomes the energy reduction (see the arrow in FIG. 4).

本発明の制御装置は、回転式全熱交換器に利用可能であり、特にローターの回転数を制御する場合に有用である。   The control device of the present invention can be used for a rotary total heat exchanger, and is particularly useful when controlling the rotational speed of a rotor.
