- Step S103 is a step of specifying the rotation output value and the blast output information according to the updated output capacity value.
- the processing unit 8b determines the magnitude relationship between the reference value stored in the storage unit 8d and the updated output capacity value. Then, when the output capacity value is equal to or less than the reference value (NO), the processing unit 8b receives the rotation output value (first rotation output value shown in FIG. 5) and the ventilation output information corresponding to the output capacity value equal to or less than the reference value.

- the humidifying device 6 turns off the blower output information when the output capacity value calculated by the processing unit 8b is equal to or less than the reference value (the output capacity value is in the range of 2000 or more and 4000 or less). In this state, the humidification process is executed with the rotation output value (rotation speed) of the humidification motor 6e in the range of 2000 rpm or more and 4000 rpm or less. On the other hand, when the output capacity value calculated by the processing unit 8b exceeds the reference value (the output capacity value is in the range of more than 4000 and 5000 or less), the humidifying device 6 rotates the humidifying motor 6e with the blower output information turned on. Humidification treatment is executed in the range where the output value (rotation speed) is more than 3000 rpm and 4000 rpm or less.

こうした構成によれば、運転動作を制御する送風装置(第一送風装置または第二送風装置)を切り替えることで、加湿装置に対して、熱交換後の給気流に付加する屋内の空気として、加湿量(屋内に供給される水分量)を増加させるのにより好ましい温湿度条件の空気を選択して供給することができる。このため、加湿機能付き熱交換形換気装置の加湿能力を効果的に向上させることができる。
According to such a configuration, by switching the blower (first blower or second blower) that controls the operation operation, the humidifier is humidified as indoor air added to the air supply after heat exchange. By increasing the amount (the amount of water supplied indoors), air under more favorable temperature and humidity conditions can be selectively supplied. Therefore, the humidifying capacity of the heat exchange type ventilator with a humidifying function can be effectively improved.
また、本開示に係る加湿機能付き熱交換形換気装置では、送風装置は、屋内の第一部屋からの空気が流通する第一風路と、屋内の第二部屋からの空気が流通する第二風路とを切り替え可能に構成される。そして、制御部は、第一部屋の空気の温湿度情報と第二部屋の空気の温湿度情報とに基づいて、第一風路と第二風路のいずれか一方を選択し、選択した風路を流通する屋内の空気を加湿装置に搬送するように送風装置の運転動作を制御するように構成してもよい。
Further, in the heat exchange type ventilator with a humidifying function according to the present disclosure, the blower is a first air passage through which air from the first indoor room circulates and a second air passage through which air from the second indoor room circulates. It is configured so that it can be switched between the air passage and the air passage. Then, the control unit selects either the first air passage or the second air passage based on the temperature / humidity information of the air in the first room and the temperature / humidity information of the air in the second room, and the selected wind. It may be configured to control the operating operation of the blower so as to convey the indoor air flowing through the road to the humidifier.
こうした構成によれば、加湿装置に屋内の空気を搬送させる風路(第一風路または第二風路)を切り替えることで、加湿装置に対して、熱交換後の給気流に付加する屋内の空気として、加湿量(屋内に供給される水分量)を増加させるのにより好ましい温湿度条件の空気を選択して供給することができる。このため、加湿機能付き熱交換形換気装置の加湿能力を効果的に向上させることができる。
According to such a configuration, by switching the air passage (first air passage or second air passage) for carrying the indoor air to the humidifier, the humidifier is added to the air supply after heat exchange indoors. As air, air with more favorable temperature and humidity conditions can be selectively supplied by increasing the amount of humidification (the amount of water supplied indoors). Therefore, the humidifying capacity of the heat exchange type ventilator with a humidifying function can be effectively improved.
また、本開示に係る加湿機能付き熱交換形換気装置では、制御部は、第一部屋の空気の温度が第二部屋の空気の温度よりも高い場合に、第一送風装置を選択して運転動作を制御することが好ましい。このようにすることで、加湿装置に対して、熱交換後の給気流に付加する屋内の空気として、屋内の空気の中でより高い温度の空気(第一部屋の空気)が供給されるので、給気流として含有させることが可能な水分量を増加させることができる。このため、加湿装置自体の出力が同じであっても給気流への加湿量(屋内に供給される水分量)を増加させることができ、加湿機能付き熱交換形換気装置の加湿能力を効果的に向上させることができる。
Further, in the heat exchange type ventilator with a humidifying function according to the present disclosure, the control unit selects and operates the first blower when the temperature of the air in the first room is higher than the temperature of the air in the second room. It is preferable to control the operation. By doing so, the humidifier is supplied with air having a higher temperature (air in the first room) in the indoor air as the indoor air added to the air supply after heat exchange. , The amount of water that can be contained as the air supply can be increased. Therefore, even if the output of the humidifier itself is the same, the amount of humidification to the air supply (the amount of water supplied indoors) can be increased, and the humidifying capacity of the heat exchange type ventilator with a humidifying function is effective. Can be improved.
また、本開示に係る加湿機能付き熱交換形換気装置では、制御部は、第一部屋の空気の湿度が第二部屋の空気の湿度よりも低い場合に、第一送風装置を選択して運転動作を制御することが好ましい。このようにすることで、加湿装置に対して、熱交換後の給気流に付加する屋内の空気として、屋内の空気の中でより低い湿度の空気(第一部屋の空気)が供給されるので、給気流として含有させることが可能な水分量を増加させることができる。このため、加湿装置自体の出力が同じであっても給気流への加湿量(屋内に供給される水分量)を増加させることができ、加湿機能付き熱交換形換気装置の加湿能力を効果的に向上させることができる。
Further, in the heat exchange type ventilator with a humidifying function according to the present disclosure, the control unit selects and operates the first blower when the humidity of the air in the first room is lower than the humidity of the air in the second room. It is preferable to control the operation. By doing so, the humidifier is supplied with air having a lower humidity (air in the first room) than the indoor air as the indoor air added to the air supply after heat exchange. , The amount of water that can be contained as the air supply can be increased. Therefore, even if the output of the humidifier itself is the same, the amount of humidification to the air supply (the amount of water supplied indoors) can be increased, and the humidifying capacity of the heat exchange type ventilator with a humidifying function is effective. Can be improved.

As shown in FIG. 2, the heat exchange type ventilator 4 with a humidifying function includes a heat exchange type ventilator 5, a humidifying device 6, and a blower 7. The humidifying device 6 and the blowing device 7 are configured such that the operation operation is controlled by the control unit 8 (see FIG. 3) described later.
熱交換形換気装置5は、屋内2の空気RA(排気流15)と屋外3の空気OA(給気流16)との間で熱交換しながら換気する装置である。具体的には、熱交換形換気装置5は、図2に示す通り、還気口5a、排気口5b、外気口5c、給気口5d、熱交換素子5e、湿度センサ5f、排気ファン5g、及び給気ファン5hを備えている。
The heat exchange type ventilation device 5 is a device that ventilates while exchanging heat between the air RA (exhaust flow 15) in the indoor 2 and the air OA (air supply 16) in the outdoor 3. Specifically, as shown in FIG. 2, the heat exchange type ventilation device 5 includes a return air port 5a, an exhaust port 5b, an outside air port 5c, an air supply port 5d, a heat exchange element 5e, a humidity sensor 5f, and an exhaust fan 5g. It also has an air supply fan 5h.
還気口5aは、屋内2の空気RA(排気流15)を還気風路9(図1参照)から熱交換形換気装置5に取り入れる取入口である。排気口5bは、排気流15を排気EAとして熱交換形換気装置5から排気風路10(図1参照)に吐き出す吐出口である。外気口5cは、屋外3の空気OA(給気流16)を外気風路11(図1参照)から熱交換形換気装置5に取り入れる取入口である。給気口5dは、給気流16を熱交換形換気装置5から中継風路12に吐き出す吐出口である。
The return air port 5a is an intake port for taking in the air RA (exhaust flow 15) of the indoor 2 from the return air air passage 9 (see FIG. 1) into the heat exchange type ventilation device 5. The exhaust port 5b is an exhaust port that discharges the exhaust flow 15 as an exhaust EA from the heat exchange type ventilator 5 to the exhaust air passage 10 (see FIG. 1). The outside air port 5c is an intake port that takes in the air OA (air supply airflow 16) of the outdoor 3 from the outside air air passage 11 (see FIG. 1) into the heat exchange type ventilation device 5. The air supply port 5d is a discharge port that discharges the air supply airflow 16 from the heat exchange type ventilation device 5 to the relay air passage 12.
熱交換素子5eは、排気流15と給気流16との間で熱交換(顕熱と潜熱)を行うための部材である。熱交換素子5eは、セルロース繊維をベースとした伝熱紙(伝熱板)によって形成された全熱交換素子である。ただし、材質はこれに限定されるものではない。熱交換素子5eを構成する伝熱板としては、例えば、ポリウレタン、ポリエチレンテレフタレートをベースとした透湿樹脂膜、あるいは、セルロース繊維、セラミック繊維、ガラス繊維をベースとした紙材料等を用いることができる。また、熱交換素子5eを構成する伝熱板は、伝熱性を備えた薄いシートであって、気体が透過しない性質のものを用いることができる。この場合、熱交換素子5eは、顕熱交換素子となる。
The heat exchange element 5e is a member for performing heat exchange (sensible heat and latent heat) between the exhaust flow 15 and the supply airflow 16. The heat exchange element 5e is a total heat exchange element formed of heat transfer paper (heat transfer plate) based on cellulose fibers. However, the material is not limited to this. As the heat transfer plate constituting the heat exchange element 5e, for example, a moisture permeable resin film based on polyurethane or polyethylene terephthalate, or a paper material based on cellulose fiber, ceramic fiber, or glass fiber can be used. .. Further, as the heat transfer plate constituting the heat exchange element 5e, a thin sheet having heat transfer properties and having a property of not allowing gas to permeate can be used. In this case, the heat exchange element 5e becomes a sensible heat exchange element.
湿度センサ5fは、還気口5aから取り入れた排気流15の湿度を検出するセンサであり、後述する制御部8の入力信号として用いられる。排気ファン5gは、排気流15を還気口5aから取り入れ、排気口5bから吐き出すための送風機である。給気ファン5hは、給気流16を外気口5cから取り入れ、給気口5dから排出するための送風機である。

When the heat exchange type ventilation device 5 performs heat exchange ventilation, the exhaust fan 5g and the air supply fan 5h are operated, and the exhaust flow 15 flowing through the internal exhaust air passage in the heat exchange element 5e and the internal supply Heat exchange is performed with the air supply air 16 flowing through the air passage. As a result, the heat exchange type ventilator 5 transfers the heat of the exhaust flow 15 released to the outdoor 3 to the air supply 16 that takes in the indoor 2 when ventilating, suppresses the release of unnecessary heat, and indoors. Recover heat to 2. As a result, in winter, when ventilating, the temperature drop of the indoor 2 can be suppressed by the air having a low temperature of the outdoor 3. On the other hand, in the summer, when ventilating, the temperature rise of the indoor 2 can be suppressed by the high temperature air of the outdoor 3.
続いて、加湿装置6は、熱交換形換気装置5からの熱交換後の給気流16と送風装置7からの屋内2の空気RA(循環流17)とを必要に応じて加湿する装置である。具体的には、加湿装置6は、図2に示す通り、給気流入口6a、循環流入口6b、給気流出口6c、及び加湿器6dを備えている。
Subsequently, the humidifying device 6 is a device that humidifies the air supply 16 after heat exchange from the heat exchange type ventilator 5 and the air RA (circulating flow 17) of the indoor 2 from the blower 7 as needed. .. Specifically, as shown in FIG. 2, the humidifying device 6 includes an air supply inlet 6a, a circulation inflow port 6b, an airflow outlet 6c, and a humidifier 6d.
給気流入口6aは、給気流16を中継風路12から加湿装置6に取り入れる取入口である。循環流入口6bは、循環流17を循環風路14から加湿装置6に取り入れる取入口である。給気流出口6cは、加湿した給気流16(熱交換形換気装置5からの給気流16、あるいは、熱交換形換気装置5からの給気流16と送風装置7からの循環流17が合流した気流)を給気SAとして給気風路13(図1参照)に吐き出す吐出口である。
The airflow inlet 6a is an intake that takes in the airflow 16 from the relay air passage 12 into the humidifying device 6. The circulation inlet 6b is an intake that takes in the circulation flow 17 from the circulation air passage 14 into the humidifying device 6. The airflow outlet 6c is a humidified airflow 16 (airflow 16 from the heat exchange type ventilator 5 or a combination of the airflow 16 from the heat exchange type ventilator 5 and the circulating flow 17 from the blower 7). ) Is used as the supply air SA and is discharged to the supply air passage 13 (see FIG. 1).
加湿器6dは、内部に取り入れた給気流16及び循環流17を加湿するためのユニットである。加湿器6dは、加湿モータ6eと加湿ノズル6fとを有している。加湿器6dは、加湿モータ6eを用いて加湿ノズル6fを回転させ、貯水されている水を遠心力で吸い上げて周囲(遠心方向)に飛散・衝突・破砕させ、通過する空気に水分を含ませる遠心破砕式の構成をとる。そして、加湿器6dは、後述する制御部8からの出力信号に応じて加湿モータ6eの回転数(以下、回転出力値)を変化させ、加湿能力(加湿量)を調整する。
The humidifier 6d is a unit for humidifying the air supply airflow 16 and the circulating flow 17 taken inside. The humidifier 6d has a humidifying motor 6e and a humidifying nozzle 6f. The humidifier 6d uses a humidifying motor 6e to rotate the humidifying nozzle 6f, sucks up the stored water by centrifugal force, scatters, collides, and crushes it in the surroundings (centrifugal direction), and impregnates the passing air with water. It has a centrifugal crushing type structure. Then, the humidifier 6d changes the rotation speed (hereinafter, rotational output value) of the humidifying motor 6e according to the output signal from the control unit 8 described later, and adjusts the humidifying capacity (humidifying amount).
なお、加湿器6dで空気に付加される液体は水以外でもよく、例えば、殺菌性あるいは消臭性を備えた次亜塩素酸水等の液体であってもよい。この場合には、次亜塩素酸水を給気流16に含ませて屋内2に供給することで、屋内2の殺菌あるいは消臭を行うことができる。
The liquid added to the air by the humidifier 6d may be a liquid other than water, for example, a liquid such as hypochlorous acid water having bactericidal or deodorant properties. In this case, the hypochlorous acid water is included in the air flow 16 and supplied to the indoor 2, so that the indoor 2 can be sterilized or deodorized.
続いて、送風装置7は、図1及び図2に示す通り、屋内2の階間または天井裏に設置され、天井面から屋内2の空気RA(循環流17)を取り入れ、加湿装置6に搬送することが可能な装置である。送風装置7は、後述する制御部8からの出力信号(以下、送風出力情報)に応じて運転動作のオン/オフが制御される。
Subsequently, as shown in FIGS. 1 and 2, the blower 7 is installed between the floors of the indoor 2 or behind the ceiling, takes in the air RA (circulation flow 17) of the indoor 2 from the ceiling surface, and conveys it to the humidifier 6. It is a device that can be used.

次に、本実施の形態1に係る加湿機能付き熱交換形換気装置4による加湿運転動作の際の制御について図3~図5を参照して説明する。図3は、加湿機能付き熱交換形換気装置4における制御部8の構成を表すブロック図である。図4は、加湿機能付き熱交換形換気装置4における制御部8の処理部8bで行う処理を表すフローチャートである。図5は、加湿機能付き熱交換形換気装置4における制御部8の処理部8bで行う処理に用いられる出力能力値と回転出力値との関係を示す図である。なお、図5では、加湿装置6(加湿モータ6e)における回転出力値(回転数)の制御範囲を2000rpm~4000rpmとし、出力能力値の範囲を2000~5000として相関関係を示している。
Next, the control during the humidification operation operation by the heat exchange type ventilation device 4 with a humidification function according to the first embodiment will be described with reference to FIGS. 3 to 5. FIG. 3 is a block diagram showing the configuration of the control unit 8 in the heat exchange type ventilation device 4 with a humidifying function. FIG. 4 is a flowchart showing a process performed by the processing unit 8b of the control unit 8 in the heat exchange type ventilation device 4 with a humidifying function. FIG. 5 is a diagram showing the relationship between the output capacity value and the rotational output value used in the processing performed by the processing unit 8b of the control unit 8 in the heat exchange type ventilation device 4 with a humidifying function. In FIG. 5, the control range of the rotation output value (rotation speed) in the humidifying device 6 (humidifying motor 6e) is set to 2000 rpm to 4000 rpm, and the range of the output capacity value is set to 2000 to 5000 to show the correlation.
制御部8は、加湿装置6及び送風装置7の運転動作を制御する。具体的には、制御部8は、図3に示す通り、入力部8a、処理部8b、出力部8c、記憶部8d、及び計時部8eを有している。操作パネル18は、屋内2に設置されており、加湿運転及び屋内2の空気RAの設定湿度(目標湿度)に関する情報を制御部8に出力する。熱交換形換気装置5の湿度センサ5fは、屋内2の空気RAの湿度(屋内湿度)に関する情報を制御部8に出力する。入力部8aは、操作パネル18から出力された情報と、熱交換形換気装置5の湿度センサ5fから出力された情報とを受け付け、処理部8bに出力する。
The control unit 8 controls the operation of the humidifying device 6 and the blower device 7. Specifically, as shown in FIG. 3, the control unit 8 has an input unit 8a, a processing unit 8b, an output unit 8c, a storage unit 8d, and a timing unit 8e. The operation panel 18 is installed indoors 2, and outputs information on the humidification operation and the set humidity (target humidity) of the air RA in the indoors 2 to the control unit 8. The humidity sensor 5f of the heat exchange type ventilator 5 outputs information on the humidity (indoor humidity) of the air RA of the indoor 2 to the control unit 8. The input unit 8a receives the information output from the operation panel 18 and the information output from the humidity sensor 5f of the heat exchange type ventilator 5, and outputs the information to the processing unit 8b.
処理部8bは、計時部8eから出力された時刻情報に基づき、一定時間間隔(例えば、5分)ごとに所定の処理を行う。具体的には、処理部8bは、記憶部8dから出力される過去の湿度情報、過去の出力能力値、及び計算用パラメータと、入力部8aから出力される現在の湿度情報とを用いて、屋内湿度を目標湿度に近づけるための出力能力値の算出を行う。処理部8bは、算出した出力能力値に基づいて、加湿装置6に対する回転出力値(加湿器6dにおける加湿モータ6eの回転数)及び送風装置7に対する送風出力情報(運転動作のオン/オフに関する情報)を特定する。処理部8bは、特定された回転出力値及び特定された送風出力情報を出力部8cに出力する。ここで、出力能力値とは、加湿機能付き熱交換形換気装置4全体での加湿能力(加湿量)の指標となる値である。なお、出力能力値は、加湿装置6によって屋内2の空気RAを目標湿度に近づけるのに必要な加湿量を特定するための値とも言える。
The processing unit 8b performs predetermined processing at regular time intervals (for example, 5 minutes) based on the time information output from the time measuring unit 8e. Specifically, the processing unit 8b uses the past humidity information output from the storage unit 8d, the past output capacity value, and the calculation parameters, and the current humidity information output from the input unit 8a. Calculate the output capacity value to bring the indoor humidity closer to the target humidity. Based on the calculated output capacity value, the processing unit 8b has a rotation output value for the humidifier 6 (rotation speed of the humidifying motor 6e in the humidifier 6d) and blower output information for the blower 7 (information regarding on / off of the operation operation). ) Is specified. The processing unit 8b outputs the specified rotation output value and the specified blast output information to the output unit 8c. Here, the output capacity value is a value that is an index of the humidification capacity (humidification amount) of the entire heat exchange type ventilation device 4 with a humidification function. The output capacity value can also be said to be a value for specifying the amount of humidification required for the humidifying device 6 to bring the air RA of the indoor 2 closer to the target humidity.
記憶部8dは、過去の湿度情報、過去の出力能力値、及び計算用パラメータを記憶するとともに、処理部8bから出力される現在の屋内湿度情報、現在の出力能力値、及び現在の送風出力情報を受け付けて記憶する。また、図5に示す出力能力値と回転出力値との相関関係に関する情報も記憶する。記憶した各情報は、処理部8bからの要求に応じて、記憶部8dから処理部8bに出力される。
The storage unit 8d stores the past humidity information, the past output capacity value, and the calculation parameters, and also stores the current indoor humidity information, the current output capacity value, and the current blast output information output from the processing unit 8b. Accept and memorize. In addition, information on the correlation between the output capacity value and the rotational output value shown in FIG. 5 is also stored. Each of the stored information is output from the storage unit 8d to the processing unit 8b in response to a request from the processing unit 8b.
出力部8cは、処理部8bから受け付けた回転出力値を、加湿装置6(加湿器6dの加湿モータ6e)に出力する。また、出力部8cは、処理部8bから受け付けた送風出力情報を送風装置7に出力する。そして、加湿装置6は、出力部8cから出力された回転出力値に応じて加湿運転動作を実行する。また、送風装置7は、出力部8cから出力された送風出力情報に基づいて送風運転動作のオン/オフを実行する。
The output unit 8c outputs the rotation output value received from the processing unit 8b to the humidifying device 6 (humidifying motor 6e of the humidifier 6d). Further, the output unit 8c outputs the blower output information received from the processing unit 8b to the blower device 7. Then, the humidifying device 6 executes the humidifying operation operation according to the rotation output value output from the output unit 8c. Further, the blower device 7 executes on / off of the blower operation operation based on the blower output information output from the output unit 8c.
次に、加湿機能付き熱交換形換気装置4における制御部8の処理部8bで行う処理フローについて説明する。
Next, the processing flow performed by the processing unit 8b of the control unit 8 in the heat exchange type ventilation device 4 with a humidifying function will be described.
制御部8の処理部8bは、図4に示す通り、主に3つのステップ(ステップS101~ステップS103)で構成され、操作パネル18からの制御信号に応じて処理を開始する。
As shown in FIG. 4, the processing unit 8b of the control unit 8 is mainly composed of three steps (steps S101 to S103), and starts processing in response to a control signal from the operation panel 18.
ステップS101は、記憶部8dに記憶された処理間隔で処理を行うためのステップである。処理部8bは、例えば、処理間隔が5分である場合、計時部8eから出力される時刻情報を受け付けながら、5分経過するまでは時刻の判定を繰り返し、5分経過したらステップS102に処理を進める。時刻の判定の際には、操作パネル18の制御信号を受け付け、終了の信号を受け付けた場合には処理を終了する。
Step S101 is a step for performing processing at the processing interval stored in the storage unit 8d. For example, when the processing interval is 5 minutes, the processing unit 8b repeats the time determination until 5 minutes elapse while receiving the time information output from the time counting unit 8e, and after 5 minutes elapses, the processing unit 8b performs processing in step S102. Proceed. When determining the time, the control signal of the operation panel 18 is received, and when the end signal is received, the process ends.
ステップS102は、出力能力値を更新するステップである。ここでは、処理部8bは、入力部8a及び記憶部8dから出力された各情報をもとに、出力能力値の更新を行い、ステップS103に処理を進める。なお、更新の際に用いる計算式としては、例えば、以下の式(1)に示す速度型PID(Proportional Integral Differential)制御式を用いることができる。
Step S102 is a step of updating the output capacity value. Here, the processing unit 8b updates the output capacity value based on each information output from the input unit 8a and the storage unit 8d, and proceeds to the process in step S103. As the calculation formula used at the time of updating, for example, the speed type PID (Proportional Integral Differential) control formula shown in the following formula (1) can be used.
R=R+Kp*[(ΔX0-ΔX1)
+(1/Ti)*ΔX0+Td*{(ΔX0-ΔX1)-(ΔX1-ΔX2)}]
・・・式(1)
ただし、Rは出力能力値であり、Kp、Ti、TdはPIDパラメータであり、ΔX0、ΔX1、ΔX2は、それぞれ現在、1回前、2回前の「目標湿度-屋内湿度」に基づく値である。 R = R + Kp * [(ΔX0-ΔX1)
+ (1 / Ti) * ΔX0 + Td * {(ΔX0-ΔX1)-(ΔX1-ΔX2)}]
... Equation (1)
However, R is an output capacity value, Kp, Ti, and Td are PID parameters, and ΔX0, ΔX1, and ΔX2 are values based on the "target humidity-indoor humidity" one time before and two times before, respectively. is there.
+(1/Ti)*ΔX0+Td*{(ΔX0-ΔX1)-(ΔX1-ΔX2)}]
・・・式(1)
ただし、Rは出力能力値であり、Kp、Ti、TdはPIDパラメータであり、ΔX0、ΔX1、ΔX2は、それぞれ現在、1回前、2回前の「目標湿度-屋内湿度」に基づく値である。 R = R + Kp * [(ΔX0-ΔX1)
+ (1 / Ti) * ΔX0 + Td * {(ΔX0-ΔX1)-(ΔX1-ΔX2)}]
... Equation (1)
However, R is an output capacity value, Kp, Ti, and Td are PID parameters, and ΔX0, ΔX1, and ΔX2 are values based on the "target humidity-indoor humidity" one time before and two times before, respectively. is there.
ステップS103は、更新された出力能力値に応じた回転出力値及び送風出力情報を特定するステップである。ここでは、処理部8bは、記憶部8dに記憶された基準値と更新された出力能力値との間で大小関係の判定を行う。そして、処理部8bは、出力能力値が基準値以下である場合(NO)に、基準値以下の出力能力値に対応する回転出力値(図5に示す第一回転出力値)及び送風出力情報として送風装置7の運転動作をオフとする情報(オフ情報)を特定する。一方、制御部8は、出力能力値が基準値を超える場合(YES)に、基準値を超える出力能力値に対応する回転出力値(図5に示す第二回転出力値)及び送風出力情報として送風装置7の運転動作をオンとする情報(オン情報)を特定する。ここで、基準値は、加湿装置6の加湿モータ6eにおいて設定可能な最大回転数に対応して規定される値である。
Step S103 is a step of specifying the rotation output value and the blast output information according to the updated output capacity value. Here, the processing unit 8b determines the magnitude relationship between the reference value stored in the storage unit 8d and the updated output capacity value. Then, when the output capacity value is equal to or less than the reference value (NO), the processing unit 8b receives the rotation output value (first rotation output value shown in FIG. 5) and the ventilation output information corresponding to the output capacity value equal to or less than the reference value. The information (off information) for turning off the operation of the blower device 7 is specified. On the other hand, when the output capacity value exceeds the reference value (YES), the control unit 8 uses the rotation output value (second rotation output value shown in FIG. 5) and the ventilation output information corresponding to the output capacity value exceeding the reference value. The information (on information) for turning on the operation of the blower 7 is specified. Here, the reference value is a value defined corresponding to the maximum rotation speed that can be set in the humidifying motor 6e of the humidifying device 6.
第一回転出力値は、図5に示す通り、出力能力値をそのまま回転出力値とした値である。一方、第二回転出力値は、出力能力値から調整値を減じて回転出力値とした値である。なお、第二回転出力値は、出力能力値に対する基準値を超えた領域における制御範囲外の第一回転出力値から調整値(厳密には調整値に対応する回転数)を減じて算出される値とも言える。
As shown in FIG. 5, the first rotation output value is a value obtained by using the output capacity value as it is as the rotation output value. On the other hand, the second rotation output value is a value obtained by subtracting the adjustment value from the output capacity value to obtain the rotation output value. The second rotation output value is calculated by subtracting the adjustment value (strictly speaking, the rotation speed corresponding to the adjustment value) from the first rotation output value outside the control range in the region exceeding the reference value for the output capacity value. It can be said to be a value.
ここで、調整値は、熱交換形換気装置5からの給気流16のみに対して加湿を行う状態(送風装置7のオフ状態)から、熱交換形換気装置5からの給気流16と送風装置7からの循環流17が合流した気流に対して加湿を行う状態(送風装置7のオン状態)に移行する際に生じる加湿能力の不連続性(加湿装置6による加湿量の急激な上昇)を低減するために設定される値である。
Here, the adjustment values are from the state in which only the air supply 16 from the heat exchange type ventilator 5 is humidified (the state in which the blower 7 is off) to the air supply 16 from the heat exchange type ventilator 5 and the air blower. The discontinuity of the humidifying capacity (rapid increase in the amount of humidification by the humidifying device 6) that occurs when shifting to the state of humidifying the airflow in which the circulating flow 17 from 7 has merged (the state in which the blower device 7 is on) This is a value set to reduce.
ステップS103における処理部8bの処理について具体的な例を挙げて説明する。上述した通り、本実施の形態では、加湿装置6(加湿モータ6e)における回転出力値(回転数)の制御範囲は、2000rpm~4000rpmであるので、基準値は、出力能力値の2000~5000の範囲のうち4000と設定される。そして、調整値を1000(回転数1000rpm)と設定する。
The processing of the processing unit 8b in step S103 will be described with a specific example. As described above, in the present embodiment, the control range of the rotation output value (rotation speed) in the humidifying device 6 (humidifying motor 6e) is 2000 rpm to 4000 rpm, so that the reference value is 2000 to 5000 of the output capacity value. It is set to 4000 out of the range. Then, the adjustment value is set to 1000 (rotation speed 1000 rpm).
上記のように設定した場合には、加湿装置6は、処理部8bで算出される出力能力値が基準値以下の場合(出力能力値が2000以上4000以下の範囲)において、送風出力情報がオフ状態で、加湿モータ6eの回転出力値(回転数)を2000rpm以上4000rpm以下の範囲で加湿処理を実行する。一方、加湿装置6は、処理部8bで算出される出力能力値が基準値を超える場合(出力能力値が4000超5000以下の範囲)において、送風出力情報がオン状態で、加湿モータ6eの回転出力値(回転数)を3000rpm超4000rpm以下の範囲で加湿処理を実行する。
In the case of setting as described above, the humidifying device 6 turns off the blower output information when the output capacity value calculated by the processing unit 8b is equal to or less than the reference value (the output capacity value is in the range of 2000 or more and 4000 or less). In this state, the humidification process is executed with the rotation output value (rotation speed) of the humidification motor 6e in the range of 2000 rpm or more and 4000 rpm or less. On the other hand, when the output capacity value calculated by the processing unit 8b exceeds the reference value (the output capacity value is in the range of more than 4000 and 5000 or less), the humidifying device 6 rotates the humidifying motor 6e with the blower output information turned on. Humidification treatment is executed in the range where the output value (rotation speed) is more than 3000 rpm and 4000 rpm or less.
以上、実施の形態1に係る加湿機能付き熱交換形換気装置4によれば、以下の効果を享受することができる。
As described above, according to the heat exchange type ventilation device 4 with a humidifying function according to the first embodiment, the following effects can be enjoyed.
(1)加湿機能付き熱交換形換気装置4では、加湿装置6の加湿量を特定する出力能力値が基準値以下である場合、熱交換後の給気流16に対して屋内2の空気RAを付加することなく加湿装置6による加湿を行い、出力能力値が基準値を超える場合、熱交換後の給気流16に対して屋内2の空気RAを付加して加湿装置6による加湿を行うようにした。このようにすることで、加湿装置6の加湿量を特定する出力能力値が基準値を超える場合に、熱交換後の給気流16に屋内2の空気RAを付加することで加湿装置6を流通する空気の風量を増加させることができる。このため、加湿装置6自体の出力が同じであっても給気流16への加湿量(屋内2に供給される水分量)を増加させることができ、加湿機能付き熱交換形換気装置4の加湿能力を向上させることができる。つまり、熱交換形換気装置5による熱交換後の給気流16への加湿量を増加させることが可能な加湿機能付き熱交換形換気装置4とすることができる。
(1) In the heat exchange type ventilation device 4 with a humidifying function, when the output capacity value for specifying the humidifying amount of the humidifying device 6 is equal to or less than the reference value, the air RA of the indoor 2 is applied to the air supply air 16 after the heat exchange. Humidification is performed by the humidifying device 6 without adding, and when the output capacity value exceeds the reference value, the air RA of the indoor 2 is added to the air supply air 16 after heat exchange to humidify by the humidifying device 6. did. By doing so, when the output capacity value for specifying the humidification amount of the humidifier 6 exceeds the reference value, the humidifier 6 is distributed by adding the air RA of the indoor 2 to the air supply air 16 after heat exchange. It is possible to increase the air volume of the air. Therefore, even if the output of the humidifying device 6 itself is the same, the amount of humidification to the air supply 16 (the amount of water supplied to the indoor 2) can be increased, and the humidification of the heat exchange type ventilation device 4 with a humidifying function can be increased. You can improve your ability. That is, the heat exchange type ventilator 4 with a humidifying function can be used, which can increase the amount of humidification to the air supply air 16 after the heat exchange by the heat exchange type ventilator 5.
(2)加湿機能付き熱交換形換気装置4では、屋内2の空気RAを加湿装置6に搬送可能に構成された送風装置7を備え、出力能力値が基準値以下である場合、送風装置7を運転動作させず、出力能力値が基準値を超える場合、送風装置7を運転動作させると構成した。このようにすることで、加湿装置6自体に空気の搬送能力がない場合であっても、屋内2の空気RAを加湿装置6に流通させることができる。つまり、加湿機能付き熱交換形換気装置4における加湿装置6の加湿能力を容易に向上させることができる。
(2) The heat exchange type ventilator 4 with a humidifying function is provided with a blower 7 configured to be able to convey the air RA of the indoor 2 to the humidifier 6, and when the output capacity value is equal to or less than the reference value, the blower 7 is provided. Is not operated, and when the output capacity value exceeds the reference value, the blower 7 is operated. By doing so, even if the humidifying device 6 itself does not have the ability to convey air, the air RA of the indoor 2 can be circulated to the humidifying device 6. That is, the humidifying capacity of the humidifying device 6 in the heat exchange type ventilator 4 with a humidifying function can be easily improved.
(3)加湿機能付き熱交換形換気装置4では、屋内2の空気RAの湿度と屋内2の空気RAの目標湿度に関する湿度情報を用いて出力能力値を算出し、算出した出力能力値に基づいて加湿装置6の運転動作を制御するように構成した。このようにすることで、屋内2の空気RAの湿度が目標湿度に近づかない場合には、湿度情報を用いて出力能力値を上昇させるなど、家屋1の気密性などの性能に依存せず目標湿度を達成するように加湿装置6の制御を行うことができる。
(3) In the heat exchange type ventilator 4 with a humidifying function, the output capacity value is calculated using the humidity information regarding the humidity of the air RA in the indoor 2 and the target humidity of the air RA in the indoor 2 and is based on the calculated output capacity value. It was configured to control the operation of the humidifying device 6. By doing so, when the humidity of the air RA in the indoor 2 does not approach the target humidity, the output capacity value is increased by using the humidity information, and the target is independent of the performance such as the airtightness of the house 1. The humidifier 6 can be controlled to achieve humidity.
(4)加湿機能付き熱交換形換気装置4によれば、熱交換形換気装置5の風量のみで運転しているだけでは給気流16に対する加湿量が足りない場合において、送風装置7から屋内2の空気RA(循環流17)を搬送して加湿装置6を流通する空気の風量を増加させることにより、加湿機能付き熱交換形換気装置4の加湿能力を容易に上昇させることが可能となる。
(4) According to the heat exchange type ventilator 4 with a humidifying function, when the humidifying amount for the air supply 16 is insufficient only by operating with only the air volume of the heat exchange type ventilator 5, the air blower 7 to the indoor 2 By increasing the air volume of the air flowing through the humidifying device 6 by transporting the air RA (circulating flow 17) of the above, the humidifying capacity of the heat exchange type ventilation device 4 with a humidifying function can be easily increased.
(5)加湿機能付き熱交換形換気装置4では、熱交換形換気装置5による熱交換後の給気流16に対して屋内2の空気RA(循環流17)を付加しているので、熱交換前の給気流16に対して屋内2の空気RAを付加する場合と比べて、熱交換形換気装置5を流通する気流の流量バランス(排気流15の流量<給気流16の流量)を調整することなく加湿装置6による加湿を行うことができる。
(5) In the heat exchange type ventilation device 4 with a humidifying function, since the air RA (circulation flow 17) of the indoor 2 is added to the air supply air 16 after the heat exchange by the heat exchange type ventilation device 5, the heat exchange The flow balance of the airflow flowing through the heat exchange type ventilation device 5 (flow rate of the exhaust flow 15 <flow rate of the supply airflow 16) is adjusted as compared with the case where the air RA of the indoor 2 is added to the previous supply airflow 16. Humidification can be performed by the humidifying device 6 without any problem.

第一循環流17aは、第一送風装置7aによって搬送される第一部屋2aの空気RAを加湿して再び屋内2の各部屋に導入する空気の流れである。第一循環流17aは、風路切替ダンパ19が第一状態の場合に、第一送風装置7a、第一循環風路14a、風路切替ダンパ19、及び第三循環風路14cを通じて、第一部屋2aから加湿装置6へと搬送される。そして、加湿装置6において加湿された第一循環流17aは、給気流16と合流した後、給気風路13を通じて加湿装置6から屋内2の各部屋へと導入される。なお、第一循環流17aは、給気流16と合流した後、加湿装置6において加湿されるようにしてもよい。
The first circulating flow 17a is an air flow that humidifies the air RA of the first room 2a conveyed by the first blower 7a and introduces it into each room of the indoor 2 again. When the air passage switching damper 19 is in the first state, the first circulating flow 17a is first passed through the first blowing device 7a, the first circulating air passage 14a, the air passage switching damper 19, and the third circulating air passage 14c. It is transported from the room 2a to the humidifying device 6. Then, the first circulating flow 17a humidified in the humidifying device 6 merges with the air supply airflow 16 and then is introduced from the humidifying device 6 into each room of the indoor 2 through the air supply air passage 13. The first circulating flow 17a may be humidified by the humidifying device 6 after merging with the air supply air 16.
一方、第二循環流17bは、第二送風装置7bによって搬送される第二部屋2bの空気RAを加湿して再び屋内2の各部屋に導入する空気の流れである。第二循環流17bは、風路切替ダンパ19が第二状態の場合に、第二送風装置7b、第二循環風路14b、風路切替ダンパ19、及び第三循環風路14cを通じて、第二部屋2bから加湿装置6へと搬送される。そして、加湿装置6において加湿された第二循環流17bは、給気流16と合流した後、給気風路13を通じて加湿装置6から屋内2の各部屋へと導入される。なお、第二循環流17bは、給気流16と合流した後、加湿装置6において加湿されるようにしてもよい。
On the other hand, the second circulating flow 17b is an air flow that humidifies the air RA of the second room 2b conveyed by the second blower 7b and introduces it into each room of the indoor 2 again. When the air passage switching damper 19 is in the second state, the second circulating flow 17b passes through the second blower 7b, the second circulating air passage 14b, the air passage switching damper 19, and the third circulating air passage 14c. It is transported from the room 2b to the humidifying device 6. Then, the second circulating flow 17b humidified in the humidifying device 6 merges with the air supply airflow 16 and then is introduced from the humidifying device 6 into each room of the indoor 2 through the air supply air passage 13. The second circulating flow 17b may be humidified by the humidifying device 6 after merging with the air supply air 16.
次に、本実施の形態2に係る加湿機能付き熱交換形換気装置4aによる加湿運転動作の際の制御について図7を参照して説明する。図7は、加湿機能付き熱交換形換気装置4aにおける制御部80の構成を表すブロック図である。
Next, the control during the humidification operation operation by the heat exchange type ventilation device 4a with a humidification function according to the second embodiment will be described with reference to FIG. 7. FIG. 7 is a block diagram showing the configuration of the control unit 80 in the heat exchange type ventilation device 4a with a humidifying function.
制御部80は、加湿装置6、第一送風装置7a、第二送風装置7b、及び風路切替ダンパ19の運転動作を制御する。制御部80は、図7に示す通り、入力部80a、処理部80b、出力部80c、記憶部80d、及び計時部80eを有している。制御部80における各部の役割は、上述した制御部8における各部の役割と対応しているので、ここでは両者の相違点に絞って説明する。
The control unit 80 controls the operation of the humidifying device 6, the first blower device 7a, the second blower device 7b, and the air passage switching damper 19. As shown in FIG. 7, the control unit 80 includes an input unit 80a, a processing unit 80b, an output unit 80c, a storage unit 80d, and a timekeeping unit 80e. Since the roles of the respective parts in the control unit 80 correspond to the roles of the respective parts in the control unit 8 described above, the differences between the two will be described here.
入力部80aは、第一温湿度センサ20aから出力された第一部屋2aの空気RAの温湿度情報と、第二温湿度センサ20bから出力された第二部屋2aの空気RAの温湿度情報とを受け付け、処理部80bに出力する。
The input unit 80a includes the temperature / humidity information of the air RA of the first room 2a output from the first temperature / humidity sensor 20a and the temperature / humidity information of the air RA of the second room 2a output from the second temperature / humidity sensor 20b. Is received and output to the processing unit 80b.
処理部80bは、図4に示したステップS103において、入力部80aから出力される各部屋の温湿度情報(第一部屋2aの空気RAの温湿度情報、第二部屋2aの空気RAの温湿度情報)に基づいて、熱交換後の給気流16に付加する屋内2の空気RAとして、加湿量(屋内2に供給される水分量)を増加させるのにより好ましい温湿度条件の空気RAを特定する。そして、処理部80bは、特定した空気RAが加湿装置6に搬送されるように、第一送風装置7aに対する送風出力情報(運転動作のオン/オフに関する情報)、第二送風装置7bに対する送風出力情報(運転動作のオン/オフに関する情報)、及び風路切替ダンパ19の切り替え情報を特定し、特定された各情報を出力部80cに出力する。
In step S103 shown in FIG. 4, the processing unit 80b outputs the temperature / humidity information of each room (the temperature / humidity information of the air RA of the first room 2a and the temperature / humidity of the air RA of the second room 2a) output from the input unit 80a. Based on the information), as the air RA of the indoor 2 to be added to the air supply air 16 after heat exchange, the air RA under more preferable temperature and humidity conditions is specified by increasing the humidification amount (the amount of water supplied to the indoor 2). .. Then, the processing unit 80b receives the blower output information (information regarding on / off of the operation operation) for the first blower device 7a and the blower output for the second blower device 7b so that the specified air RA is conveyed to the humidifying device 6. Information (information regarding on / off of driving operation) and switching information of the air passage switching damper 19 are specified, and each of the specified information is output to the output unit 80c.
出力部80cは、処理部80bから受け付けた各送風出力情報を第一送風装置7a及び第二送風装置7bのそれぞれに出力する。そして、第一送風装置7a及び第二送風装置7bは、出力部80cから出力された送風出力情報に基づいて送風運転動作のオン/オフを実行する。また、出力部80cは、処理部80bから受け付けた切り替え情報を風路切替ダンパ19に出力する。そして、風路切替ダンパ19は、出力部80cから出力された切り替え情報に基づいて、第一状態(第一送風装置7aと加湿装置6との間が連通する状態)と第二状態(第二送風装置7bと加湿装置6との間が連通する状態)とを切り替える。
The output unit 80c outputs each blower output information received from the processing unit 80b to each of the first blower device 7a and the second blower device 7b. Then, the first blower device 7a and the second blower device 7b execute the on / off of the blower operation operation based on the blower output information output from the output unit 80c. Further, the output unit 80c outputs the switching information received from the processing unit 80b to the air passage switching damper 19. Then, the air passage switching damper 19 has a first state (a state in which the first blower 7a and the humidifying device 6 communicate with each other) and a second state (a second state) based on the switching information output from the output unit 80c. (A state in which the blower 7b and the humidifier 6 communicate with each other) is switched.
これにより、加湿機能付き熱交換形換気装置4aでは、加湿装置6の加湿量を特定する出力能力値が基準値を超える場合に、熱交換後の給気流16に対して第一送風装置7aによって搬送される第一部屋2aからの空気RA(第一循環流17a)を付加して給気SAとして供給する状態と、熱交換後の給気流16に対して第二送風装置7bによって搬送される第二部屋2bからの空気RA(第二循環流17b)を付加して給気SAとして供給する状態とを切り替えて対応することが可能となる。
As a result, in the heat exchange type ventilation device 4a with a humidifying function, when the output capacity value for specifying the humidification amount of the humidifying device 6 exceeds the reference value, the first air blower 7a is used for the air supply 16 after the heat exchange. The air RA (first circulating flow 17a) from the first chamber 2a to be transported is added and supplied as an air supply SA, and the air supply air 16 after heat exchange is conveyed by the second blower 7b. It is possible to switch between a state in which air RA (second circulation flow 17b) from the second room 2b is added and supplied as air supply SA.
より詳細な処理部80bにおける制御例は、以下の通りである。
A more detailed control example in the processing unit 80b is as follows.
<制御例A>
入力部80aから出力される各部屋の温湿度情報のうち、各部屋の温度情報(第一部屋2aの空気RAの温度情報、第二部屋2aの空気RAの温度情報)に基づいて、処理部80bが行う制御例Aについて説明する。 <Control example A>
Of the temperature and humidity information of each room output from theinput unit 80a, the processing unit is based on the temperature information of each room (temperature information of air RA in the first room 2a, temperature information of air RA in the second room 2a). A control example A performed by 80b will be described.
入力部80aから出力される各部屋の温湿度情報のうち、各部屋の温度情報(第一部屋2aの空気RAの温度情報、第二部屋2aの空気RAの温度情報)に基づいて、処理部80bが行う制御例Aについて説明する。 <Control example A>
Of the temperature and humidity information of each room output from the
制御例Aでは、処理部80bは、第一部屋2aの空気RAの温度と第二部屋2bの空気RAの温度とを比較し、第一部屋2aの空気RAの温度が第二部屋2bの空気RAの温度よりも高い場合に、熱交換後の給気流16に付加する屋内2の空気RAとして、第一部屋2aの空気RAを特定する。つまり、処理部80bは、加湿量を増加させるのにより好ましい温湿度条件の空気RAとして、第一部屋2aの空気RAを用いることを特定する。そして、処理部80bは、特定した第一部屋2aの空気RAが加湿装置6に搬送されるように、第一送風装置7aに対する送風出力情報(運転動作のオンに関する情報)、第二送風装置7bに対する送風出力情報(運転動作のオフに関する情報)、及び風路切替ダンパ19の切り替え情報(第一状態)を特定し、特定された各情報を出力部80cに出力する。
In control example A, the processing unit 80b compares the temperature of the air RA of the first room 2a with the temperature of the air RA of the second room 2b, and the temperature of the air RA of the first room 2a is the temperature of the air RA of the second room 2b. When the temperature is higher than the temperature of RA, the air RA of the first room 2a is specified as the air RA of the indoor 2 added to the air supply airflow 16 after heat exchange. That is, the processing unit 80b specifies that the air RA of the first room 2a is used as the air RA under more favorable temperature and humidity conditions for increasing the humidification amount. Then, the processing unit 80b receives the blower output information (information regarding the on of the operation operation) for the first blower device 7a and the second blower device 7b so that the air RA of the specified first room 2a is conveyed to the humidifying device 6. The blower output information (information regarding the off of the operation operation) and the switching information (first state) of the air passage switching damper 19 are specified, and each of the specified information is output to the output unit 80c.
これにより、加湿装置6に対して、熱交換後の給気流16に付加する屋内2の空気RAとして、屋内2の空気RAの中でより高い温度の空気(第一部屋2aの空気RA)が供給されるので、給気SAとして含有させることが可能な水分量を増加させることができる。
As a result, as the air RA of the indoor 2 added to the air supply 16 after heat exchange with respect to the humidifier 6, air having a higher temperature than the air RA of the indoor 2 (air RA of the first room 2a) is generated. Since it is supplied, the amount of water that can be contained as the air supply SA can be increased.
<制御例B>
入力部80aから出力される各部屋の温湿度情報のうち、各部屋の湿度情報(第一部屋2aの空気RAの湿度情報、第二部屋2aの空気RAの湿度情報)に基づいて、処理部80bが行う制御例Bについて説明する。 <Control example B>
Of the temperature and humidity information of each room output from theinput unit 80a, the processing unit is based on the humidity information of each room (humidity information of air RA of first room 2a, humidity information of air RA of second room 2a). A control example B performed by 80b will be described.
入力部80aから出力される各部屋の温湿度情報のうち、各部屋の湿度情報(第一部屋2aの空気RAの湿度情報、第二部屋2aの空気RAの湿度情報)に基づいて、処理部80bが行う制御例Bについて説明する。 <Control example B>
Of the temperature and humidity information of each room output from the
制御例Bでは、処理部80bは、第一部屋2aの空気RAの湿度と第二部屋2bの空気RAの湿度とを比較し、第一部屋2aの空気RAの湿度が第二部屋2bの空気RAの湿度よりも低い場合に、熱交換後の給気流16に付加する屋内2の空気RAとして、第一部屋2aの空気RAを特定する。つまり、処理部80bは、加湿量を増加させるのにより好ましい温湿度条件の空気RAとして、第一部屋2aの空気RAを用いることを特定する。そして、処理部80bは、特定した第一部屋2aの空気RAが加湿装置6に搬送されるように、第一送風装置7aに対する送風出力情報(運転動作のオンに関する情報)、第二送風装置7bに対する送風出力情報(運転動作のオフに関する情報)、及び風路切替ダンパ19の切り替え情報(第一状態)を特定し、特定された各情報を出力部80cに出力する。
In control example B, the processing unit 80b compares the humidity of the air RA of the first room 2a with the humidity of the air RA of the second room 2b, and the humidity of the air RA of the first room 2a is the humidity of the air RA of the second room 2b. When the humidity is lower than the humidity of RA, the air RA of the first room 2a is specified as the air RA of the indoor 2 added to the air supply airflow 16 after heat exchange. That is, the processing unit 80b specifies that the air RA of the first room 2a is used as the air RA under more favorable temperature and humidity conditions for increasing the amount of humidification. Then, the processing unit 80b receives the blower output information (information regarding the on of the operation operation) for the first blower device 7a and the second blower device 7b so that the air RA of the specified first room 2a is conveyed to the humidifier device 6. The blower output information (information regarding the off of the operation operation) and the switching information (first state) of the air passage switching damper 19 are specified, and each of the specified information is output to the output unit 80c.
これにより、加湿装置6に対して、熱交換後の給気流16に付加する屋内2の空気RAとして、屋内2の空気RAの中でより低い湿度の空気(第一部屋2aの空気RA)が供給されるので、給気SAとして含有させることが可能な水分量を増加させることができる。
As a result, as the air RA of the indoor 2 added to the air supply air 16 after heat exchange with respect to the humidifier 6, air having a lower humidity than the air RA of the indoor 2 (air RA of the first room 2a) is generated. Since it is supplied, the amount of water that can be contained as the air supply SA can be increased.
以上、実施の形態2に係る加湿機能付き熱交換形換気装置4aによれば、以下の効果を享受することができる。
As described above, according to the heat exchange type ventilation device 4a with a humidifying function according to the second embodiment, the following effects can be enjoyed.
(1)加湿機能付き熱交換形換気装置4aでは、運転動作を制御する送風装置(第一送風装置7aまたは第二送風装置7b)を切り替えることで、加湿装置6に対して、熱交換後の給気流16に付加する屋内2の空気RAとして、加湿量(屋内2に供給される水分量)を増加させるのにより好ましい温湿度条件の空気を選択して供給することができる。このため、加湿機能付き熱交換形換気装置4aの加湿能力を効果的に向上させることができる。
(1) In the heat exchange type ventilator 4a with a humidifying function, by switching the blower (first blower 7a or second blower 7b) that controls the operation operation, the humidifier 6 is exchanged for heat. As the air RA of the indoor 2 added to the air supply air 16, air under more favorable temperature and humidity conditions can be selected and supplied by increasing the humidification amount (the amount of water supplied to the indoor 2). Therefore, the humidifying capacity of the heat exchange type ventilator 4a with a humidifying function can be effectively improved.
(2)加湿機能付き熱交換形換気装置4aでは、第一部屋2aの空気RAの温度が第二部屋2bの空気RAの温度よりも高い場合に、第一送風装置7aを選択して運転動作を制御するようにした(制御例A)。これにより、加湿装置6に対して、熱交換後の給気流16に付加する屋内2の空気RAとして、屋内2の空気RAの中でより高い温度の空気(第一部屋2aの空気RA)が供給されるので、給気流16として含有させることが可能な水分量を増加させることができる。このため、加湿装置6自体の出力が同じであっても給気流16への加湿量(屋内2に供給される水分量)を増加させることができ、加湿機能付き熱交換形換気装置4aの加湿能力を効果的に向上させることができる。
(2) In the heat exchange type ventilator 4a with a humidifying function, when the temperature of the air RA in the first room 2a is higher than the temperature of the air RA in the second room 2b, the first blower 7a is selected for operation. (Control example A). As a result, as the air RA of the indoor 2 added to the air supply 16 after heat exchange with respect to the humidifying device 6, air having a higher temperature than the air RA of the indoor 2 (air RA of the first room 2a) is generated. Since it is supplied, the amount of water that can be contained as the supply airflow 16 can be increased. Therefore, even if the output of the humidifying device 6 itself is the same, the amount of humidification to the air supply 16 (the amount of water supplied to the indoor 2) can be increased, and the heat exchange type ventilation device 4a with a humidifying function can be humidified. The ability can be effectively improved.
(3)加湿機能付き熱交換形換気装置4aでは、第一部屋2aの空気RAの湿度が第二部屋2bの空気RAの湿度よりも低い場合に、第一送風装置7aを選択して運転動作を制御するようにした(制御例B)。これにより、加湿装置6に対して、熱交換後の給気流16に付加する屋内2の空気RAとして、屋内2の空気RAの中でより低い湿度の空気(第一部屋2aの空気RA)が供給されるので、給気流16として含有させることが可能な水分量を増加させることができる。このため、加湿装置6自体の出力が同じであっても給気流16への加湿量(屋内に供給される水分量)を増加させることができ、加湿機能付き熱交換形換気装置4aの加湿能力を効果的に向上させることができる。
(3) In the heat exchange type ventilator 4a with a humidifying function, when the humidity of the air RA in the first room 2a is lower than the humidity of the air RA in the second room 2b, the first blower 7a is selected for operation. (Control example B). As a result, as the air RA of the indoor 2 added to the air supply 16 after heat exchange with respect to the humidifier 6, air having a lower humidity than the air RA of the indoor 2 (air RA of the first room 2a) is generated. Since it is supplied, the amount of water that can be contained as the supply airflow 16 can be increased. Therefore, even if the output of the humidifying device 6 itself is the same, the amount of humidification to the air supply 16 (the amount of water supplied indoors) can be increased, and the humidifying capacity of the heat exchange type ventilation device 4a with a humidifying function can be increased. Can be effectively improved.

The humidifying device 6, the blower device 7c, the first opening / closing damper 21a, and the second opening / closing damper 21b are configured such that their respective operation operations are controlled by the control unit 81 (see FIG. 9). The first circulation air passage 14a corresponds to the "first air passage" of the claim, and the second circulation air passage 14b corresponds to the "second air passage" of the claim.
送風装置7cは、屋内2の階間または天井裏に設置され、屋内2における第一部屋2aの空気RA(第一循環流17a)または屋内2における第二部屋2bの空気RA(第二循環流17b)を加湿装置6に搬送可能に構成された装置である。具体的には、送風装置7cは、第一循環流17aを加湿装置6に搬送する場合には、第一部屋2aの天井面から第一開閉ダンパ21a及び第一循環風路14aを介して第一部屋2aの空気RAを取り入れ、第三循環風路14cを介して加湿装置6に搬送する。一方、送風装置7cは、第二循環流17bを加湿装置6に搬送する場合には、第二部屋2bの天井面から第二開閉ダンパ21b及び第二循環風路14bを介して第二部屋2bの空気RAを取り入れ、第三循環風路14cを介して加湿装置6に搬送する。そして、送風装置7cは、制御部81からの送風出力情報に応じて運転動作のオン/オフが制御される。ここで、送風装置7cの運転動作時の制御方法については、実施の形態1の送風装置7の運転動作時の制御方法と同じであるので説明を省略する。

Then, the blower device 7c is controlled to turn on / off the operation operation according to the blower output information from the control unit 81. Here, the control method during the operation of the blower 7c is the same as the control method during the operation of the blower 7 of the first embodiment, and thus the description thereof will be omitted.
第一開閉ダンパ21aは、第一部屋2aの天井面に設置される。第一開閉ダンパ21aは、第一部屋2aと送風装置7cとの間を連通して第一部屋2aからの空気RA(第一循環流17a)が流通する開状態と、第一部屋2aと送風装置7cとの間を遮蔽して第一部屋2aからの空気RA(第一循環流17a)が流通しない閉状態とを切り替えるためのダンパである。そして、第一開閉ダンパ21aは、制御部81からの送風出力情報に応じて開状態と閉状態との間の切り替えが制御される。

The first opening / closing damper 21a communicates between the first room 2a and the blower 7c, and the air RA (first circulation flow 17a) from the first room 2a flows in the open state, and the first room 2a and the blower are blown. It is a damper for switching between a closed state in which the air RA (first circulating flow 17a) from the first room 2a does not flow by shielding the device 7c. Then, the first opening / closing damper 21a is controlled to switch between the open state and the closed state according to the ventilation output information from the control unit 81.
一方、第二開閉ダンパ21bは、第二部屋2bの天井面に設置される。第二開閉ダンパ21bは、第二部屋2bと送風装置7cとの間を連通して第二部屋2bからの空気RA(第二循環流17b)が流通する開状態と、第二部屋2bと送風装置7cとの間を遮蔽して第二部屋2bからの空気RA(第二循環流17b)が流通しない閉状態とを切り替えるためのダンパである。そして、第二開閉ダンパ21bは、制御部81からの送風出力情報に応じて開状態と閉状態との間の切り替えが制御される。

次に、本実施の形態3に係る加湿機能付き熱交換形換気装置4bによる加湿運転動作の際の制御について図9を参照して説明する。図9は、加湿機能付き熱交換形換気装置4bにおける制御部81の構成を表すブロック図である。
Next, the control during the humidification operation operation by the heat exchange type ventilation device 4b with a humidification function according to the third embodiment will be described with reference to FIG. FIG. 9 is a block diagram showing the configuration of the control unit 81 in the heat exchange type ventilation device 4b with a humidifying function.
制御部81は、加湿装置6、送風装置7c、第一開閉ダンパ21a、及び第二開閉ダンパ21bの運転動作を制御する。制御部81は、図9に示す通り、入力部81a、処理部81b、出力部81c、記憶部81d、及び計時部81eを有している。制御部81における各部の役割は、上述した制御部80における各部の役割と対応しているので、ここでは両者の相違点に絞って説明する。
The control unit 81 controls the operation of the humidifying device 6, the blower 7c, the first opening / closing damper 21a, and the second opening / closing damper 21b. As shown in FIG. 9, the control unit 81 includes an input unit 81a, a processing unit 81b, an output unit 81c, a storage unit 81d, and a timekeeping unit 81e. Since the roles of the respective parts in the control unit 81 correspond to the roles of the respective parts in the control unit 80 described above, the differences between the two will be described here.
入力部81aは、第一温湿度センサ20aから出力された第一部屋2aの空気RAの温湿度情報と、第二温湿度センサ20bから出力された第二部屋2aの空気RAの温湿度情報とを受け付け、処理部81bに出力する。
The input unit 81a includes the temperature / humidity information of the air RA of the first room 2a output from the first temperature / humidity sensor 20a and the temperature / humidity information of the air RA of the second room 2a output from the second temperature / humidity sensor 20b. Is received and output to the processing unit 81b.
処理部81bは、実施の形態2における制御部80の処理部80bと同様、入力部81aから出力される各部屋の温湿度情報(第一部屋2aの空気RAの温湿度情報、第二部屋2aの空気RAの温湿度情報)に基づいて、熱交換後の給気流16に付加する屋内2の空気RAとして、加湿量(屋内2に供給される水分量)を増加させるのにより好ましい温湿度条件の空気RAを特定する。そして、処理部81bは、特定した空気RAが加湿装置6に搬送されるように、送風装置7cに対する送風出力情報(運転動作のオン/オフに関する情報)、第一開閉ダンパ21aの開閉情報、及び第二開閉ダンパ21bの開閉情報を特定し、特定された各情報を出力部81cに出力する。
Similar to the processing unit 80b of the control unit 80 in the second embodiment, the processing unit 81b has temperature / humidity information of each room output from the input unit 81a (temperature / humidity information of air RA in the first room 2a, second room 2a). The temperature and humidity conditions of the indoor 2 to be added to the air supply air after heat exchange 16 based on the temperature and humidity information of the air RA of the above, which is more preferable to increase the humidification amount (the amount of water supplied to the indoor 2). Identify the air RA of. Then, the processing unit 81b provides the blower output information (information regarding on / off of the operation operation) to the blower device 7c, the opening / closing information of the first opening / closing damper 21a, and the opening / closing information of the first opening / closing damper 21a so that the specified air RA is conveyed to the humidifying device 6. The opening / closing information of the second opening / closing damper 21b is specified, and each of the specified information is output to the output unit 81c.
出力部81cは、処理部81bから受け付けた送風出力情報を送風装置7cに出力する。そして、送風装置7cは、出力部81cから出力された送風出力情報に基づいて送風運転動作のオン/オフを実行する。また、出力部81cは、処理部81bから受け付けた開閉情報を第一開閉ダンパ21a及び第二開閉ダンパ21bにそれぞれ出力する。そして、第一開閉ダンパ21a及び第二開閉ダンパ21bは、出力部81cから出力された開閉情報に基づいて、各ダンパの開閉を実行する。具体的には、第一部屋2aの空気RA(第一循環流17a)が加湿装置6に搬送される状態(第一開閉ダンパ21a:開状態/第二開閉ダンパ21b:閉状態)または第二部屋2bの空気RA(第二循環流17b)が加湿装置6に搬送される状態(第一開閉ダンパ21a:閉状態/第二開閉ダンパ21b:開状態)となるように、各ダンパの開閉を実行する。なお、こうした開閉切り替えは、第一部屋2aからの空気RA(第二循環流17b)が流通する第一循環風路14aと、第二部屋2bからの空気RA(第二循環流17b)が流通する第二循環風路14bのいずれか一方を選択して、選択した風路に切り替えることに相当する。
The output unit 81c outputs the blower output information received from the processing unit 81b to the blower device 7c. Then, the blower device 7c executes on / off of the blower operation operation based on the blower output information output from the output unit 81c. Further, the output unit 81c outputs the opening / closing information received from the processing unit 81b to the first opening / closing damper 21a and the second opening / closing damper 21b, respectively. Then, the first opening / closing damper 21a and the second opening / closing damper 21b execute opening / closing of each damper based on the opening / closing information output from the output unit 81c. Specifically, the air RA (first circulation flow 17a) of the first room 2a is conveyed to the humidifying device 6 (first opening / closing damper 21a: open state / second opening / closing damper 21b: closed state) or second. Open and close each damper so that the air RA (second circulation flow 17b) in the room 2b is conveyed to the humidifying device 6 (first open / close damper 21a: closed state / second open / close damper 21b: open state). Execute. In such opening / closing switching, the first circulation air passage 14a through which the air RA (second circulation flow 17b) from the first room 2a circulates and the air RA (second circulation flow 17b) from the second room 2b circulate. It corresponds to selecting one of the second circulating air passages 14b to switch to the selected air passage.
これにより、加湿機能付き熱交換形換気装置4bでは、加湿装置6の加湿量を特定する出力能力値が基準値を超える場合に、熱交換後の給気流16に対して第一部屋2aからの空気RA(第一循環流17a)を付加して給気SAとして供給する状態と、熱交換後の給気流16に対して第二部屋2bからの空気RA(第二循環流17b)を付加して給気SAとして供給する状態とを切り替えて対応することが可能となる。
As a result, in the heat exchange type ventilator 4b with a humidifying function, when the output capacity value for specifying the humidification amount of the humidifying device 6 exceeds the reference value, the air supply air 16 after heat exchange is sent from the first room 2a. Air RA (first circulation flow 17a) is added and supplied as supply air SA, and air RA (second circulation flow 17b) from the second room 2b is added to the supply airflow 16 after heat exchange. It is possible to switch between the state of supplying as air supply SA and the state of being supplied.
なお、処理部81bでは、実施の形態2で示した制御例(制御例A、制御例B)と同様の制御がなされている。
Note that the processing unit 81b performs the same control as the control examples (control example A, control example B) shown in the second embodiment.

(実施の形態4)
従来、冷房あるいは暖房の効果低減を抑制しつつ換気を行うことが可能な装置として、換気の際に給気流と排気流との間で熱交換を行う熱交換形換気装置が知られている。 (Embodiment 4)
Conventionally, as a device capable of performing ventilation while suppressing a reduction in the effect of cooling or heating, a heat exchange type ventilation device that exchanges heat between a supply air flow and an exhaust flow during ventilation is known.
従来、冷房あるいは暖房の効果低減を抑制しつつ換気を行うことが可能な装置として、換気の際に給気流と排気流との間で熱交換を行う熱交換形換気装置が知られている。 (Embodiment 4)
Conventionally, as a device capable of performing ventilation while suppressing a reduction in the effect of cooling or heating, a heat exchange type ventilation device that exchanges heat between a supply air flow and an exhaust flow during ventilation is known.
こうした熱交換形換気装置は、顕熱に加えて潜熱も交換する機能が備わっているため、屋内の保湿効果も得ることができるが、それだけで屋外絶対湿度の低い冬季における屋内相対湿度の低下を防ぐことは困難である。そこで、熱交換形換気装置として、給気風路の下流側に加湿装置を設けた構成とした加湿機能付き熱交換形換気装置が開発されている(例えば、特許文献1)。この構成により、屋内に加湿された空気を供給することができ、冬季における屋内相対湿度の低下を抑制することができる。
Since such a heat exchange type ventilator has a function of exchanging latent heat in addition to sensible heat, it is possible to obtain an indoor moisturizing effect, but by itself, the decrease in indoor relative humidity in winter when the outdoor absolute humidity is low can be obtained. It is difficult to prevent. Therefore, as a heat exchange type ventilator, a heat exchange type ventilator with a humidifying function has been developed in which a humidifying device is provided on the downstream side of the air supply air passage (for example, Patent Document 1). With this configuration, humidified air can be supplied indoors, and a decrease in indoor relative humidity in winter can be suppressed.
しかしながら、従来の加湿機能付き熱交換形換気装置では、熱交換形換気装置において熱交換された給気流がそのまま加湿装置に導入される構成となっているため、熱交換形換気装置からの給気が停止して給気流が導入されなくなった場合に加湿を継続することができていない。
However, in the conventional heat exchange type ventilator with a humidifying function, the air supply air exchanged in the heat exchange type ventilator is directly introduced into the humidifying device, so that the air is supplied from the heat exchange type ventilator. Humidification cannot be continued when the air supply stops and the air supply is not introduced.
そこで本開示は、上記従来の課題を解決するものであり、熱交換形換気装置からの給気流の流通が停止しても加湿を継続することが可能な加湿機能付き熱交換形換気装置を提供することを目的とする。
Therefore, the present disclosure solves the above-mentioned conventional problems, and provides a heat exchange type ventilator with a humidifying function capable of continuing humidification even if the flow of airflow from the heat exchange type ventilator is stopped. The purpose is to do.

It is provided with a control unit that controls the operation operation of the device and the operation operation of the blower device. Then, the control unit controls the humidifying device to circulate the indoor air conveyed to the blower when the flow of the air supply from the heat exchange type ventilator to the humidifying device is stopped.
こうした構成によれば、熱交換形換気装置から加湿装置への給気流の流通が停止した場合でも加湿装置へ空気を供給させることができ、加湿を継続することができる。つまり、熱交換形換気装置からの給気流の流通が停止しても加湿を継続することが可能な加湿機能付き熱交換形換気装置とすることができる。
According to such a configuration, air can be supplied to the humidifier even when the flow of the air supply from the heat exchange type ventilator to the humidifier is stopped, and the humidification can be continued. That is, it is possible to provide a heat exchange type ventilator with a humidifying function capable of continuing humidification even if the flow of airflow from the heat exchange type ventilator is stopped.
また、本開示に係る加湿機能付き熱交換形換気装置では、制御部は、熱交換形換気装置から加湿装置への給気流の流通が再開した場合に、送風装置から加湿装置への屋内の空気の搬送を停止させるように制御するように構成してもよい。

According to such a configuration, when the flow of the air supply from the heat exchange type ventilator to the humidifier is resumed, the increase in the air volume of the air supplied to the humidifier can be suppressed, and the room is excessively humidified. Can be prevented.
また、本開示に係る加湿機能付き熱交換形換気装置では、熱交換形換気装置の運転動作をさらに制御し、屋外の空気に関する温度情報及び屋内の空気に関する湿度情報に基づいて、熱交換形換気装置から加湿装置への給気流の流通を停止または再開させるように制御するように構成してもよい。

こうした構成によれば、屋外の空気に関する温度情報及び屋内の空気に関する湿度情報の各条件によって熱交換形換気装置から加湿装置への給気流の流通の停止または再開がなされるので、熱交換形換気装置の結露あるいは凍結を未然に防止することができる。
According to such a configuration, the flow of the air supply from the heat exchange type ventilator to the humidifier is stopped or restarted according to each condition of the temperature information about the outdoor air and the humidity information about the indoor air, so that the heat exchange type ventilation is performed. It is possible to prevent dew condensation or freezing of the device.
また、本開示に係る加湿機能付き熱交換形換気装置では、加湿装置によって加湿された加湿後空気の絶対湿度を記憶する記憶部をさらに備える。そして、制御部は、熱交換形換気装置から加湿装置への給気流の流通が停止した場合に、記憶部に記憶された、給気流の流通が停止した時点での加湿後空気の絶対湿度を保持するように、送風装置から加湿装置へ搬送される屋内の空気に対する加湿量を制御するように構成してもよい。
Further, the heat exchange type ventilator with a humidifying function according to the present disclosure further includes a storage unit that stores the absolute humidity of the air after humidification humidified by the humidifying device.

It may be configured to control the amount of humidification for the indoor air conveyed from the blower to the humidifier so as to hold it.
こうした構成によれば、熱交換形換気装置から加湿装置への給気流の流通の停止前後で、屋内に供給される加湿後空気の絶対湿度が既定の条件に保持されるので、屋内の利用者の快適性を損なうことなく、屋内の空気に対する加湿を継続することができる。

Humidification of indoor air can be continued without compromising comfort.

The input unit 82a is output from the operation panel 18, the information output from the humidity sensor 5f of the heat exchange type ventilation device 5, the information output from the OA temperature sensor 22, and the RA humidity sensor 23. Receives the information and outputs it to the processing unit 82b.
処理部82bは、計時部82eから出力された時刻情報に基づき、一定時間間隔(例えば、5分)ごとに所定の処理を行う。具体的には、処理部82bは、記憶部82dから出力される過去の屋内湿度、過去の加湿出力値、及び計算用パラメータと、入力部82aから出力される現在の屋内湿度(第一屋内湿度、第二屋内湿度)とを用いて、屋内湿度を目標湿度に近づけるための加湿出力の算出を行う。処理部82bは、算出した加湿出力に基づいて、加湿装置6に対する回転出力値(加湿器6dにおける加湿モータ6eの回転数)を特定する。処理部82bは、特定された回転出力値を出力部82cに出力する。また、処理部82bは、入力部82aから出力される現在の屋外3の温度情報及び屋内2の湿度情報を用いて、熱交換形換気装置5に対する熱交出力情報(熱交換形換気装置5の運転動作のオン/オフに関する情報)及び送風装置7に対する送風出力情報(送風装置7の運転動作のオン/オフに関する情報)を特定して出力部82cに出力する。
The processing unit 82b performs predetermined processing at regular time intervals (for example, 5 minutes) based on the time information output from the time measuring unit 82e. Specifically, the processing unit 82b has the past indoor humidity, the past humidification output value, and the calculation parameters output from the storage unit 82d, and the current indoor humidity (first indoor humidity) output from the input unit 82a. , Second indoor humidity) to calculate the humidification output to bring the indoor humidity closer to the target humidity. The processing unit 82b specifies the rotation output value for the humidifying device 6 (the number of rotations of the humidifying motor 6e in the humidifier 6d) based on the calculated humidifying output. The processing unit 82b outputs the specified rotation output value to the output unit 82c. Further, the processing unit 82b uses the current temperature information of the outdoor 3 and the humidity information of the indoor 2 output from the input unit 82a to provide heat exchange output information to the heat exchange type ventilation device 5 (heat exchange type ventilation device 5). The information regarding the on / off of the operation operation) and the ventilation output information for the blower device 7 (information regarding the on / off of the operation operation of the blower device 7) are specified and output to the output unit 82c.

The humidifying device 6 executes a humidifying operation operation according to the rotation output value output from the output unit 82c. Further, the blower device 7 executes on / off of the blower operation operation based on the blower output information output from the output unit 82c.
次に、加湿機能付き熱交換形換気装置4cにおける制御部82の処理部82bで行う処理フローについて説明する。
Next, the processing flow performed by the processing unit 82b of the control unit 82 in the heat exchange type ventilation device 4c with a humidifying function will be described.
制御部82の処理部82bは、図12に示す通り、主に4つのステップ(ステップS201~ステップS204)で構成され、操作パネル18からの制御信号に応じて、熱交換換気を行いつつ、加湿処理を開始する。なお、加湿処理の開始時点では、送風装置7は運転動作しておらず、送風装置7は停止した状態となっている。
As shown in FIG. 12, the processing unit 82b of the control unit 82 is mainly composed of four steps (steps S201 to S204), and humidifies while performing heat exchange ventilation in response to a control signal from the operation panel 18. Start processing. At the start of the humidification process, the blower device 7 is not in operation and the blower device 7 is in a stopped state.
ステップS201は、記憶部82dに記憶された処理間隔で処理を行うためのステップである。処理部82bは、例えば、処理間隔が5分である場合、計時部82eから出力される時刻情報を受け付けながら、5分経過するまでは時刻の判定を繰り返し、5分経過したらステップS202に処理を進める。時刻の判定の際には、操作パネル18の制御信号を受け付け、制御信号として終了の信号を受け付けた場合には加湿処理を終了する。なお、加湿処理が終了しても熱交換換気は継続される。
Step S201 is a step for performing processing at the processing interval stored in the storage unit 82d. For example, when the processing interval is 5 minutes, the processing unit 82b repeats the time determination until 5 minutes elapse while receiving the time information output from the time counting unit 82e, and after 5 minutes elapses, the processing unit 82b performs processing in step S202. Proceed. When determining the time, the control signal of the operation panel 18 is received, and when the end signal is received as the control signal, the humidification process is ended. The heat exchange ventilation is continued even after the humidification treatment is completed.
ステップS202は、加湿における回転出力値を更新するステップである。ここでは、処理部82bは、入力部82a及び記憶部82dから出力された各情報をもとに、回転出力値の更新を行い、ステップS203に処理を進める。なお、更新の際に用いる計算式としては、例えば、以下の式(2)に示す速度型PID制御式を用いることができる。
Step S202 is a step of updating the rotation output value in humidification. Here, the processing unit 82b updates the rotation output value based on each information output from the input unit 82a and the storage unit 82d, and proceeds to the process in step S203. As the calculation formula used at the time of updating, for example, the speed type PID control formula shown in the following formula (2) can be used.
R=R+Kp*[(ΔX0-ΔX1)
+(1/Ti)*ΔX0+Td*{(ΔX0-ΔX1)-(ΔX1-ΔX2)}] ・・・式(2)
ただし、Rは回転出力値であり、Kp、Ti、TdはPIDパラメータであり、ΔX0、ΔX1、ΔX2は、それぞれ現在、1回前、2回前の「目標湿度-屋内湿度」に基づく値である。 R = R + Kp * [(ΔX0-ΔX1)
+ (1 / Ti) * ΔX0 + Td * {(ΔX0-ΔX1)-(ΔX1-ΔX2)}] ・ ・ ・ Equation (2)
However, R is a rotation output value, Kp, Ti, and Td are PID parameters, and ΔX0, ΔX1, and ΔX2 are values based on the "target humidity-indoor humidity" one time before and two times before, respectively. is there.
+(1/Ti)*ΔX0+Td*{(ΔX0-ΔX1)-(ΔX1-ΔX2)}] ・・・式(2)
ただし、Rは回転出力値であり、Kp、Ti、TdはPIDパラメータであり、ΔX0、ΔX1、ΔX2は、それぞれ現在、1回前、2回前の「目標湿度-屋内湿度」に基づく値である。 R = R + Kp * [(ΔX0-ΔX1)
+ (1 / Ti) * ΔX0 + Td * {(ΔX0-ΔX1)-(ΔX1-ΔX2)}] ・ ・ ・ Equation (2)
However, R is a rotation output value, Kp, Ti, and Td are PID parameters, and ΔX0, ΔX1, and ΔX2 are values based on the "target humidity-indoor humidity" one time before and two times before, respectively. is there.
ステップS203は、熱交換形換気装置の運転動作(熱交換形換気装置の停止または再開)を特定するためのステップである。処理部82bは、入力部82aから出力された現在の屋外3の空気OAの温度情報及び屋内2の空気RAの湿度情報をもとに、熱交換形換気装置5の運転または停止を特定する熱交出力情報を出力し、ステップS204に処理を進める。なお、熱交出力情報を特定する際に用いる条件式としては、例えば、以下の式(3)に示す論理式を用いることができる。
Step S203 is a step for specifying the operation operation of the heat exchange type ventilator (stop or restart of the heat exchange type ventilator). The processing unit 82b determines the operation or stop of the heat exchange type ventilation device 5 based on the current temperature information of the air OA of the outdoor 3 and the humidity information of the air RA of the indoor 2 output from the input unit 82a. The exchange output information is output, and the process proceeds to step S204. As the conditional expression used when specifying the heat exchange output information, for example, the logical expression shown in the following expression (3) can be used.
P=[{(t_OA-T)/|t_OA-T|+1}/2]
*[{(X-x_RA)/|X-x_RA|+1)}/2] ・・・式(3)
ただし、t_OA=T、x_RA=Xを含む場合はこの限りではなく、t_OA=Tかつx_RA>X、もしくはt_OA<Tかつx_RA=XにときはP=0、それ以外の場合はP=1とする。ここで、Pは熱交出力情報であり、P=1で運転、P=0で停止を意味する。また、T、Xは基準温度、基準湿度であり、t_OA、x_RAはそれぞれ現在の屋外温度、屋内湿度である。本実施の形態では、屋内温度-30℃未満で装置内での凍結防止のために熱交運転を停止させるので、T=-30、X=100と設定している。 P = [{(t_OA-T) / | t_OA-T | + 1} / 2]
* [{(X-x_RA) / | X-x_RA | + 1)} / 2] ... Equation (3)
However, this does not apply when t_OA = T and x_RA = X are included, and P = 0 when t_OA = T and x_RA> X or t_OA <T and x_RA = X, and P = 1 in other cases. To do. Here, P is heat exchange output information, and P = 1 means operation and P = 0 means stop. Further, T and X are the reference temperature and the reference humidity, and t_OA and x_RA are the current outdoor temperature and the indoor humidity, respectively. In the present embodiment, since the heat exchange operation is stopped at an indoor temperature of less than −30 ° C. to prevent freezing in the apparatus, T = -30 and X = 100 are set.
*[{(X-x_RA)/|X-x_RA|+1)}/2] ・・・式(3)
ただし、t_OA=T、x_RA=Xを含む場合はこの限りではなく、t_OA=Tかつx_RA>X、もしくはt_OA<Tかつx_RA=XにときはP=0、それ以外の場合はP=1とする。ここで、Pは熱交出力情報であり、P=1で運転、P=0で停止を意味する。また、T、Xは基準温度、基準湿度であり、t_OA、x_RAはそれぞれ現在の屋外温度、屋内湿度である。本実施の形態では、屋内温度-30℃未満で装置内での凍結防止のために熱交運転を停止させるので、T=-30、X=100と設定している。 P = [{(t_OA-T) / | t_OA-T | + 1} / 2]
* [{(X-x_RA) / | X-x_RA | + 1)} / 2] ... Equation (3)
However, this does not apply when t_OA = T and x_RA = X are included, and P = 0 when t_OA = T and x_RA> X or t_OA <T and x_RA = X, and P = 1 in other cases. To do. Here, P is heat exchange output information, and P = 1 means operation and P = 0 means stop. Further, T and X are the reference temperature and the reference humidity, and t_OA and x_RA are the current outdoor temperature and the indoor humidity, respectively. In the present embodiment, since the heat exchange operation is stopped at an indoor temperature of less than −30 ° C. to prevent freezing in the apparatus, T = -30 and X = 100 are set.
ステップS204は、設定された熱交換形換気装置5の運転動作状況に応じて送風装置7の運転動作を特定するステップである。ステップS204は、図12に示す通り、主に3つの処理(ステップS204A~ステップS204C)で構成される。以下、各ステップでの処理フローについて詳細に説明する。
Step S204 is a step of specifying the operation operation of the blower device 7 according to the set operation operation state of the heat exchange type ventilation device 5. As shown in FIG. 12, step S204 is mainly composed of three processes (steps S204A to S204C). Hereinafter, the processing flow in each step will be described in detail.
ステップS204Aは、ステップS203において特定される熱交出力情報がP=1(運転)である場合に、送風装置7の運転動作を停止するステップである。具体的には、送風装置7が運転動作を停止している場合には、そのまま停止状態を維持し、送風装置7が運転動作を行っている場合には、運転動作を停止する。つまり、ステップS204Aは、送風装置7からの循環流17の搬送を停止するステップとも言える。ここでは、処理部82bは、送風出力情報として送風運転動作のオフ情報を出力する。そして、ステップS201に戻る。
Step S204A is a step of stopping the operation of the blower 7 when the heat exchange output information specified in step S203 is P = 1 (operation). Specifically, when the blower device 7 has stopped the operation operation, the stopped state is maintained as it is, and when the blower device 7 is performing the operation operation, the operation operation is stopped. That is, step S204A can be said to be a step of stopping the transport of the circulating flow 17 from the blower device 7. Here, the processing unit 82b outputs the off information of the blower operation operation as the blower output information. Then, the process returns to step S201.
ステップS204Bは、ステップS203において特定される熱交出力情報がP=0(停止)である場合に、送風装置7の運転動作を開始するステップあるいは送風装置7の運転動作を継続させるステップである。つまり、ステップS204Bは、送風装置7からの循環流17の搬送を開始または継続するステップとも言える。ここでは、処理部82bは、送風出力情報として送風運転動作のオン情報を出力する。そして、ステップS204Cに処理を進める。
Step S204B is a step of starting the operation operation of the blower device 7 or a step of continuing the operation operation of the blower device 7 when the heat exchange output information specified in step S203 is P = 0 (stop). That is, step S204B can be said to be a step of starting or continuing the transfer of the circulating flow 17 from the blower device 7. Here, the processing unit 82b outputs the ON information of the blower operation operation as the blower output information. Then, the process proceeds to step S204C.
ステップS204Cは、送風装置7からの循環流17に対する加湿量を特定するステップである。ここでは、処理部82bは、記憶部82dに記憶された熱交換形換気装置5から加湿装置6への給気流16の流通が停止した時点(あるいは停止する直前)での加湿後空気(加湿された給気流16)の絶対湿度情報をもとに、循環流17に対する加湿量(加湿装置6の回転出力値)を特定する。具体的には、記憶部82dに記憶された、給気流16の流通が停止した時点での加湿後空気の絶対湿度と現在の屋内2の空気RA(循環流17)の絶対湿度とを比較し、給気流16の流通が停止した時点での加湿後空気の絶対湿度を保持するように、循環流17に対する加湿量(加湿装置6の回転出力値)を特定し、出力部82cに出力する。そして、ステップS201のようにして、一定時間(例えば、5分)が経過した後、ステップS203に戻る。
Step S204C is a step of specifying the amount of humidification for the circulating flow 17 from the blower 7. Here, the processing unit 82b is the post-humidified air (humidified) at the time when the flow of the air supply 16 from the heat exchange type ventilator 5 stored in the storage unit 82d to the humidifying device 6 is stopped (or immediately before the stop). The amount of humidification (rotational output value of the humidifying device 6) with respect to the circulating flow 17 is specified based on the absolute humidity information of the air supply airflow 16). Specifically, the absolute humidity of the humidified air stored in the storage unit 82d at the time when the flow of the air supply 16 is stopped is compared with the absolute humidity of the current air RA (circulating flow 17) of the indoor 2 indoors 2. The amount of humidification (rotational output value of the humidifying device 6) for the circulating flow 17 is specified and output to the output unit 82c so as to maintain the absolute humidity of the air after humidification when the flow of the air supply 16 is stopped. Then, as in step S201, after a certain period of time (for example, 5 minutes) has elapsed, the process returns to step S203.
なお、ステップS204Cの処理によって、熱交換形換気装置5からの給気流16の流通が停止した場合でも、送風装置7の運転動作により搬送される循環流17によって屋内2の空気RAを一定の速さで加湿することが可能になる。そして、本実施の形態では、熱交換形換気装置5から加湿装置6への給気流16の流通が停止している間、必要加湿量の特定は、屋内2から搬送される循環流17に関する湿度情報のみによって決定され、加湿装置6の回転出力値を制御することによって行われる。
Even if the flow of the airflow 16 from the heat exchange type ventilator 5 is stopped by the process of step S204C, the air RA in the indoor 2 is kept at a constant speed by the circulating flow 17 conveyed by the operation of the blower 7. It becomes possible to humidify with the air. Then, in the present embodiment, while the flow of the air supply 16 from the heat exchange type ventilation device 5 to the humidifying device 6 is stopped, the required humidification amount is specified by the humidity related to the circulating flow 17 conveyed from the indoor 2. It is determined only by information and is performed by controlling the rotation output value of the humidifying device 6.
以上のように、制御部82は、処理部82bにおける上述の処理を継続して行うことで、熱交換形換気装置5、加湿装置6、及び送風装置7の運転動作を制御している。
As described above, the control unit 82 controls the operating operations of the heat exchange type ventilation device 5, the humidifying device 6, and the blower device 7 by continuously performing the above-mentioned processing in the processing unit 82b.
以上、実施の形態4に係る加湿機能付き熱交換形換気装置4cによれば、以下の効果を享受することができる。

(1)加湿機能付き熱交換形換気装置4cでは、熱交換形換気装置5から加湿装置6への給気流16の流通が停止した場合に、給気流に替えて送風装置7から搬送される循環流17を流通させて加湿を行うようにした。このようにすることで、装置内での結露または凍結などの防止のために熱交換形換気装置5から加湿装置6への給気流16の流通が停止した場合でも、送風装置7を通じて加湿装置6へ空気(循環流17)を流通させるので、加湿を継続させることができる。つまり、熱交換形換気装置5からの給気流16の流通が停止しても加湿を継続できるような加湿機能付き熱交換形換気装置4cとすることができる。
(1) In the heat exchange type ventilator 4c with a humidifying function, when the flow of the air supply 16 from the heat exchange type ventilator 5 to the humidifying device 6 is stopped, the circulation is conveyed from the air blower 7 instead of the air supply. The stream 17 was circulated to humidify. By doing so, even if the flow of the air supply 16 from the heat exchange type ventilation device 5 to the humidifying device 6 is stopped in order to prevent dew condensation or freezing in the device, the humidifying device 6 is passed through the blower device 7. Since air (circulating flow 17) is circulated to the air, humidification can be continued.

(2)加湿機能付き熱交換形換気装置4cでは、熱交換形換気装置5から加湿装置6への給気流16が再開されて流通した場合に、送風装置7から加湿装置6へ流通する循環流17を停止させるようにした。このようにすることで、熱交換形換気装置5の運転動作により給気流16の流通が再開した場合に、加湿装置6へ流入する空気の風量の総和が急激に増加することを抑制することができ、給気過多によって屋内2が過剰に加湿されることを防止することができる。
(2) In the heat exchange type ventilator 4c with a humidifying function, when the air supply 16 from the heat exchange type ventilator 5 to the humidifying device 6 is restarted and circulated, the circulating flow flowing from the blower 7 to the humidifying device 6 17 was stopped. By doing so, it is possible to suppress a sudden increase in the total air volume of the air flowing into the humidifying device 6 when the flow of the air supply air 16 is restarted due to the operating operation of the heat exchange type ventilation device 5. It is possible to prevent the indoor 2 from being excessively humidified due to excessive air supply.
(3)加湿機能付き熱交換形換気装置4cでは、屋外3の空気OAに関する温度情報及び屋内2の空気RAに関する湿度情報を用いて熱交換形換気装置5から加湿装置6への給気流16の流通を停止または再開させるようにした。このようにすることで、屋外3の空気OAの温度及び屋内2の空気RAの湿度の各条件によって熱交換形換気装置5から加湿装置6への給気流の流通の停止または再開がなされるので、熱交換形換気装置5の結露あるいは凍結を未然に防止することができる。
(3) In the heat exchange type ventilator 4c with a humidifying function, the airflow 16 from the heat exchange type ventilator 5 to the humidifying device 6 is used by using the temperature information regarding the air OA of the outdoor 3 and the humidity information regarding the air RA of the indoor 2 The distribution was stopped or restarted. By doing so, the flow of the air supply from the heat exchange type ventilator 5 to the humidifier 6 is stopped or restarted depending on each condition of the temperature of the air OA in the outdoor 3 and the humidity of the air RA in the indoor 2. , It is possible to prevent dew condensation or freezing of the heat exchange type ventilation device 5.
(4)加湿機能付き熱交換形換気装置4cでは、熱交換形換気装置5から加湿装置6への給気流16の流通の停止前後で、屋内2に供給される加湿後空気の絶対湿度が既定の条件に保持されるようにした。このようにすることで、屋内2の利用者の快適性を損なうことなく、屋内2の空気RAに対する加湿を継続することができる。
(4) In the heat exchange type ventilator 4c with a humidifying function, the absolute humidity of the humidified air supplied to the indoor 2 is set as the default before and after the flow of the air supply 16 from the heat exchange type ventilator 5 to the humidifying device 6 is stopped. It was made to be maintained in the condition of. By doing so, it is possible to continue humidifying the air RA of the indoor 2 without impairing the comfort of the user of the indoor 2.
(5)加湿機能付き熱交換形換気装置4cでは、屋内2の空気RAに関する湿度情報に基づいて、送風装置7から加湿装置6に搬送される屋内2の空気RAに対する加湿量を制御するようにした。このようにすることで、熱交換形換気装置5から加湿装置6への給気流16の流通が停止した後も、屋内2の利用者にとって快適な加湿状態を維持することができる。
(5) In the heat exchange type ventilator 4c with a humidifying function, the amount of humidification for the air RA of the indoor 2 conveyed from the blower 7 to the humidifying device 6 is controlled based on the humidity information regarding the air RA of the indoor 2. did. By doing so, even after the flow of the airflow 16 from the heat exchange type ventilation device 5 to the humidifying device 6 is stopped, the humidified state that is comfortable for the user indoors 2 can be maintained.

For example, as a humidifier 6d, an ultrasonic type configuration in which water particles are scattered by ultrasonic waves, a heating type configuration in which water vapor is generated by heating, vaporization in which water is vaporized by passing air through a filter coated with water or the like. It may be a structure of an expression or a combination of these. When these are adopted, the amplitude of ultrasonic waves, the amount of heating, and the amount of water dripping onto the filter may be used as parameter values corresponding to the output capacity values.
また、加湿機能付き熱交換形換気装置4aでは、制御例Aとして、制御部80は、第一部屋2aの空気RAの温度が第二部屋2bの空気RAの温度よりも高い場合に、第一送風装置7aを選択して運転動作を制御するようにしたが、これに限られない。例えば、制御部80は、第一部屋2aの空気RAの温度が第二部屋2bの空気RAの温度よりも低い場合に、第一送風装置7aを選択して運転動作を制御するようにしてもよい。この場合には、屋内ドアなどを通じて相対的に温度の高い第二部屋2bの空気RAが第一部屋2aに移動するので、第一部屋2aの空気RAの温度が上昇し、第一部屋2aの空気RAの相対湿度を低下させることができる。このため、第一部屋2aにおいて相対湿度が上昇することによって生じる結露の発生を抑制することができる。
Further, in the heat exchange type ventilator 4a with a humidifying function, as a control example A, the control unit 80 is first when the temperature of the air RA in the first room 2a is higher than the temperature of the air RA in the second room 2b. The blower 7a is selected to control the operation operation, but the present invention is not limited to this. For example, the control unit 80 may select the first blower device 7a to control the operation operation when the temperature of the air RA in the first room 2a is lower than the temperature of the air RA in the second room 2b. Good. In this case, since the air RA of the second room 2b, which has a relatively high temperature, moves to the first room 2a through the indoor door or the like, the temperature of the air RA of the first room 2a rises, and the temperature of the air RA of the first room 2a rises. The relative humidity of the air RA can be reduced. Therefore, it is possible to suppress the occurrence of dew condensation caused by the increase in relative humidity in the first room 2a.
また、加湿機能付き熱交換形換気装置4aでは、制御例Bとして、制御部80は、第一部屋2aの空気RAの湿度が第二部屋2bの空気RAの湿度よりも低い場合に、第一送風装置7aを選択して運転動作を制御するようにしたが、これに限られない。例えば、制御部80は、第一部屋2aの空気RAの湿度が第二部屋2bの空気RAの湿度よりも高い場合に、第一送風装置7aを選択して運転動作を制御するようにしてもよい。この場合には、屋内ドアなどを通じて相対的に湿度の低い第二部屋2bの空気RAが第一部屋2aに移動するので、第一部屋2aの空気RAの相対湿度を低下させることができる。このため、相対的に湿度の高い第一部屋2aにおいて結露の発生を抑制することができる。
Further, in the heat exchange type ventilator 4a with a humidifying function, as a control example B, the control unit 80 is first when the humidity of the air RA in the first room 2a is lower than the humidity of the air RA in the second room 2b. The blower 7a is selected to control the operation operation, but the present invention is not limited to this. For example, when the humidity of the air RA in the first room 2a is higher than the humidity of the air RA in the second room 2b, the control unit 80 may select the first blower device 7a to control the operation operation. Good. In this case, since the air RA of the second room 2b, which has a relatively low humidity, moves to the first room 2a through an indoor door or the like, the relative humidity of the air RA of the first room 2a can be reduced. Therefore, the occurrence of dew condensation can be suppressed in the first room 2a where the humidity is relatively high.
また、加湿機能付き熱交換形換気装置4aでは、熱交換後の給気流16に対して第一部屋2aからの空気RA(第一循環流17a)を付加して給気SAとして供給する状態と、熱交換後の給気流16に対して第二送風装置7bによって搬送される第二部屋2bからの空気RA(第二循環流17b)を付加して給気SAとして供給する状態とを切り替えるようにしたが、これに限られない。例えば、制御部80は、第一部屋2aからの空気RA(第一循環流17a)を付加する際に、第一循環流17aより少ない風量で、第二部屋2bからの空気RA(第二循環流17b)を付加するようにしてもよい。この場合には、屋内2全体での空気RAの循環量を増加させることにより、相対的に湿度の低い部屋の湿度を高く、相対的に湿度の高い部屋の湿度を低くすることができ、より快適な室内空間を実現することができる。
Further, in the heat exchange type ventilator 4a with a humidifying function, the air RA (first circulating flow 17a) from the first chamber 2a is added to the air supply air 16 after the heat exchange and supplied as the air supply SA. , To switch between a state in which air RA (second circulation flow 17b) from the second chamber 2b conveyed by the second blower 7b is added to the supply airflow 16 after heat exchange and supplied as air supply SA. However, it is not limited to this. For example, when the control unit 80 adds the air RA (first circulation flow 17a) from the first room 2a, the air volume from the first room 2b is smaller than that of the first circulation flow 17a, and the air RA (second circulation) from the second room 2b. The flow 17b) may be added. In this case, by increasing the circulation amount of air RA in the entire indoor 2 room, the humidity of the room with relatively low humidity can be increased and the humidity of the room with relatively high humidity can be lowered. A comfortable indoor space can be realized.
また、加湿機能付き熱交換形換気装置4cを構成する送風装置7では、送風能力(風量)を固定とし、制御部82からの送風出力情報に応じて運転動作のオン/オフのみで制御されるように構成したが、これに限られない。例えば、送風装置7は、送風装置7の運転動作のオン/オフの制御に加え、運転動作がオンの場合に送風装置7の送風能力を可変として制御されるように構成されてもよい。このようにすることで、ステップS204Cにおいて、循環流17に対する加湿量を特定する際の設定自由度を向上させることができる。
Further, in the blower device 7 constituting the heat exchange type ventilator 4c with a humidifying function, the blower capacity (air volume) is fixed and controlled only by turning on / off the operation operation according to the blower output information from the control unit 82. However, it is not limited to this. For example, the blower device 7 may be configured to be controlled so that the blower capacity of the blower device 7 is variably controlled when the operation operation is on, in addition to controlling the operation operation of the blower device 7 to be on / off. By doing so, in step S204C, the degree of freedom in setting when specifying the humidification amount for the circulating flow 17 can be improved.
本開示に係る加湿機能付き熱交換形換気装置は、屋内の空気と屋外の空気との間での熱交換を可能とする熱交換形換気装置に加湿機能を備えたものとして有用である。
The heat exchange type ventilator with a humidifying function according to the present disclosure is useful as a heat exchange type ventilator capable of exchanging heat between indoor air and outdoor air as having a humidifying function.
