Transmit to ventilator NO.2 (N2) and ventilator NO.4 (N4). Therefore, the ventilation device NO.1 (N1), the ventilation device NO.2 (N2), and the ventilation device NO.4 (N4) are controlled based on the detection signal (d1).
- the second transmitting / receiving unit (64) also receives the detection signal (d3) of the ventilator NO.3 (N3).
- the second transmission / reception unit (64) transmits a detection signal (d3) corresponding to the ventilation device NO.3 (N3) set to “single” to the first transmission / reception unit (53) of the ventilation device NO.3 (N3). ).
- the control device (50) corresponding to the ventilator NO.3 (N3) controls the ventilator NO.3 (N3) based on the rewritten detection signal (d3).
- the ventilator NO. 3 (N3) set to “single” is controlled based on the detection signal (d3) of the second carbon dioxide concentration sensor (40b) connected to itself.
- each ventilation device In the ventilation system (10) of the present embodiment, an operation of turning on all the ventilation devices (20) and an operation of turning off all the ventilation devices (20) are switched. That is, from the second transmission / reception unit (64) of the remote controller (60), an operation command for turning on all the ventilation devices (20) and an operation command for turning off all the ventilation devices (20) are issued to each ventilation unit ( U) is transmitted to the control device (50). On the other hand, the remote controller (60) does not transmit an operation command for turning on a part of all the ventilators (20) and turning off the rest.
- the common ventilator (20-o) to which the carbon dioxide concentration sensor (40) is attached is turned off and the common ventilator (20-s) sharing the detection signal is turned on, the operation is performed.

For this reason, even when the ventilation device (20) to which the carbon dioxide concentration sensor (40) is attached is changed due to, for example, a change in the layout of the indoor space, the common ventilation device (20-o) is correspondingly changed. And the common ventilator (20-s) can be changed easily.
- the setting unit (63) can set a single ventilator (20-i) that does not belong to the sharing source and the sharing destination of the carbon dioxide concentration sensor (40).
- the ventilator (20) can be controlled based on its own carbon dioxide concentration sensor (40).
- the operation of turning on a part of all the ventilators (20) and turning off the rest is prohibited. For this reason, the common ventilator (20-s) is stopped and the common ventilator (20-s) is in operation. It is possible to reliably avoid the problem that the control cannot be performed.

Description
複数の換気装置(20)と、
前記複数の換気装置(20)の中の所定の換気装置(20)に取り付けられるとともに、空気の状態を検出するセンサ(40,40a)と、
前記複数の換気装置(20)の中から、前記センサ(40,40a)を取り付ける対象である第1換気装置(20-o)と、該センサ(40,40a)の検出信号を共有させる対象である第2換気装置(20-s)とを設定する設定部(63)と、
前記センサ(40,40a)の検出信号を受信するとともに、前記設定部(63)に設定した前記第1換気装置(20-o)及び第2換気装置(20-s)の各制御装置(50)に前記検出信号を送信する送受信部(64)とを備え、
前記各制御装置(50)は、前記送受信部(64)から送信された前記検出信号に基づいて、対応する換気装置(20)をそれぞれ制御することを特徴とする換気システムである。
前記複数の換気装置(20)の運転指令を前記各制御装置(50)に送信するリモコン(60)を備え、
前記設定部(63)及び前記送受信部(64)は、前記リモコン(60)に設けられることを特徴とする換気システムである。
前記リモコン(60)は、前記第1換気装置(20-o)をOFFさせ、前記第2換気装置(20-s)をONさせる運転指令を送信しないことを特徴とする換気システムである。
前記リモコン(60)は、
前記複数の換気装置(20)の全てをONさせる第1運転指令と、前記複数の換気装置(20)の全てをOFFさせる第2運転指令とを送信する一方、
前記複数の換気装置(20)の一部をONさせ、残りをOFFさせる運転指令を送信しないことを特徴とする換気システムである。
前記設定部(63)には、前記複数の換気装置(20)の中から、前記第1換気装置(20-o)及び前記第2換気装置(20-s)を変更可能に設定されることを特徴とする換気システムである。
前記第1換気装置(20-o)から前記送受信部(64)に、前記センサ(40,40a)の検出信号が受信されないときに、異常を示す信号を出力する異常判定部(65)を備えていることを特徴とする換気システムである。
実施形態に係る換気システム(10)は、複数の換気ユニット(U)を備えている。複数の換気ユニット(U)は、同一の室内空間を換気対象としている。換気ユニット(U)は、例えば天井裏に配置される。図1に模式的に示すように、本例の換気システム(10)には、4台の換気ユニット(U)が設けられている。換気ユニット(U)の数量はこれに限らず、2台以上であれば如何なる数量であってもよい。各換気ユニット(U)は、換気装置(20)と制御装置(50)とをそれぞれ1つずつ備えている。
各換気装置(20)の概略構成について図2を参照しながら説明する。各換気装置(20)は、ケーシング(21)、給気ファン(31)、排気ファン(32)、全熱交換器(33)、及び二酸化炭素濃度センサ(40)をそれぞれ備えている。
制御装置(50)は、例えば制御基板と、制御基板に搭載されたプロセッサ(例えばマイクロコントローラ)と、該プロセッサを動作させるためのソフトウェアを格納するメモリディバイス(例えば半導体メモリ)とを有する。
図1に示すように、リモコン(60)は、全ての換気ユニット(U)に共用される。リモコン(60)は、各換気装置(20)に運転指令を送信する。図3に示すように、リモコン(60)は、表示部(61)、操作部(62)、設定部(63)、第2送受信部(64)、及び異常判定部(65)を備える。
換気装置(20)の基本的な運転動作について、図2を参照しながら説明する。換気装置(20)の換気運転時には、給気ファン(31)及び排気ファン(32)が運転状態となる。この結果、室外空気(OA)が外気口(22)を通じて給気通路(26)に取り込まれると同時に、室内空気(RA)が内気口(24)を通じて排気通路(27)に取り込まれる。
換気システム(10)では、1つの二酸化炭素濃度センサ(40)を、複数の換気装置(20)の制御に利用できる。まず、二酸化炭素濃度センサ(40)の取り付け、及び設定部(63)の設定例について、具体例を挙げながら説明する。
このような換気装置(20)の制御動作について、図5のフローチャートを参照しながら説明する。
図4に示す例において、例えば換気装置NO.1(N1)の制御装置(50)に二酸化炭素濃度センサ(40)が正しく接続されなかったとする。この場合、第2送受信部(64)には、共有元換気装置(20-o)である換気装置NO.1(N1)の検出信号(d1)が正しく受信されない。この場合、異常判定部(65)は異常を示す信号を出力する。表示部(61)は、この信号を受けて異常を示すサインを表示する。この結果、施工業者やユーザ等は、二酸化炭素濃度センサ(40)の接続ミス、接続不良、故障等を速やかに把握できる。
図6の例では、二酸化炭素濃度センサ(40)が換気装置NO.2(N2)に取り付けられる。一方、二酸化炭素濃度センサ(40)は、他の換気装置NO.1(N1)、換気装置NO.3(N3)、及び換気装置NO.4(N4)には取り付けられない。この場合、設定部(63)では、換気装置NO.2(N2)を「共有元」に設定し、換気装置NO.1(N1)、換気装置NO.3(N3)、及び換気装置NO.4(N4)を「共有先」に設定する。この場合、換気装置NO.2(N2)の検出信号(d2)が、リモコン(60)の第2送受信部(64)に送信される。第2送受信部(64)は、この検出信号(d2)を、共有元換気装置(20-o)である換気装置NO.2(N2)と、共有先換気装置(20-s)である換気装置NO.1(N1)、換気装置NO.3(N3)、及び換気装置NO.4(N4)とに送信する。これにより、検出信号(d2)が換気装置NO.1~NO.4(N1,N2,N3,N4)の制御に共用される。
図7の例では、第1二酸化炭素濃度センサ(40a)が換気装置NO.1(N1)に取り付けられ、第2二酸化炭素濃度センサ(40b)が換気装置NO.3(N3)に取り付けられる。本例の設定部(63)では、第1二酸化炭素濃度センサ(40a)の検出信号を、換気装置NO.1(N1)、換気装置NO.2(N2)、及び換気装置NO.4(N4)で共用する。一方、第2二酸化炭素濃度センサ(40b)の検出信号は、単独換気装置(20-i)に設定される換気装置NO.3(N3)のみに利用される。
本実施形態の換気システム(10)では、全ての換気装置(20)をONさせる動作と、全ての換気装置(20)をOFFさせる動作とが切り換えられる。つまり、リモコン(60)の第2送受信部(64)からは、全ての換気装置(20)をONさせる運転指令と、全ての換気装置(20)をOFFさせる運転指令とが、各換気ユニット(U)の制御装置(50)に送信される。一方、リモコン(60)は、全ての換気装置(20)の中の一部をONさせ、残りをOFFさせる運転指令を送信しない。
上記実施形態によれば、共有元換気装置(20-o)に対応する二酸化炭素濃度センサ(40)の検出信号を、第2送受信部(64)から共有元換気装置(20-o)及び共有先換気装置(20-s)の各制御装置(50)に送信する。そして、共有元換気装置(20-o)及び共有先換気装置(20-s)は、この検出信号に基づいて、対応する換気装置(20)を制御する。このため、本実施形態によれば、全ての換気装置(20)にそれぞれ二酸化炭素濃度センサ(40)を設けずとも、各換気装置(20)を制御できる。この結果、二酸化炭素濃度センサ(40)の数量を削減できる。
上記実施形態において、リモコン(60)は、共有元換気装置(20-o)をOFFさせ、且つ共有先換気装置(20-s)をONさせる運転指令を送信しないように構成されてもよい。例えば、リモコン(60)の設定部(63)に共有元換気装置(20-o)及び共有先換気装置(20-s)が設定された場合、この設定に応じて、上記運転指令が禁止される。具体的には、リモコン(60)では、共有元換気装置(20-o)をOFF、共有先換気装置(20-s)をONさせる運転指令が禁止される一方、共有元換気装置(20-o)をON、共有先換気装置(20-s)をOFFさせる運転指令は許容される。このようにしても、共有元換気装置(20-o)が停止状態となり、且つ共有先換気装置(20-s)が運転状態になることに起因して、共有先換気装置(20-s)を適切に制御できなくなる不具合を確実に回避できる。また、共有元換気装置(20-o)だけをONさせながら、該共有元換気装置(20-o)の二酸化炭素濃度センサ(40)に基づいて換気運転を行うことができる。
上記実施形態及び変形例は、以下のような構成としてもよい。
20 換気装置
40 二酸化炭素濃度センサ(センサ)
40a 第1二酸化炭素濃度センサ(センサ)
50 制御装置
