  The ventilation system according to the embodiment can operate the heat exchange ventilator 3 in two modes. In the first mode, by operating both the exhaust fan 4 and the air supply fan 5, heat exchange between the air exhausted outside the house and the air supplied into the house is performed by the heat exchange element 18. This is the mode to perform. The second mode is a mode in which heat is not exchanged between the air exhausted outside the house and the air supplied into the house by stopping the exhaust fan 4 and operating only the air supply fan 5. It is.

  FIG. 4 is a configuration diagram illustrating the ventilation system in a state where the heat exchange ventilation apparatus is operated in the first mode. The air taken in from the house by the exhaust fan 4 is exhausted to the outside after passing through the heat exchange element 18. The air taken in from the outside by the air supply fan 5 passes through the heat exchange element 18 and is supplied to the house. Accordingly, in the heat exchange element 18, heat exchange is performed between the air exhausted outside the house and the air supplied into the house. While the heat exchange ventilator 3 is operated in the first mode, the sanitary exhaust device 7, the toilet exhaust device 8, and the range hood fan 19 are manually operated only after use in the bathroom, toilet, kitchen, etc. Exhaust air, toilets, LDK, etc. to the outside.

  FIG. 5 is a configuration diagram showing the ventilation system in a state where the heat exchange ventilation apparatus 3 is operated in the second mode. Since the exhaust fan 4 is stopped and only the air supply fan 5 is operating, only the air taken in from the outdoors by the air supply fan 5 passes through the heat exchange element 18. Therefore, heat exchange between the air exhausted outside the house and the air supplied into the house is not performed in the heat exchange element 18. While the heat exchange ventilator 3 is operated in the second mode, an exhaust device installed separately from the heat exchange ventilator 3, that is, the sanitary exhaust device 7, the toilet exhaust device 8, the range hood fan 19, etc. It is necessary to exhaust indoor air to the outdoors by driving.

  Here, a method for storing setting information in the setting information storage unit 106 will be described. FIG. 6 is an explanatory diagram of a setting screen for the ventilation system of the remote control device. The remote control device 2 is an electronic device that can communicate with the home equipment centralized management device 1 via the home wireless communication network 12 or the public wireless communication network 13, and includes a mobile phone terminal, a smart phone terminal, a tablet terminal, a notebook computer, A PDA (personal digital assistant) or the like can be applied. The setting screen displayed on the remote control device 2 includes an exhaust operation stop function setting field 15, a notification setting field 16 when exhaust operation is stopped, and an exhaust device setting field 17 linked when exhaust operation is stopped.

  The exhaust operation stop function setting column 15 is a column for setting whether or not to use the function of stopping the exhaust fan 4 of the heat exchange ventilator 3. The notification setting column 16 when the exhaust operation is stopped and the exhaust device setting column 17 that is linked when the exhaust operation is stopped can be set only when the exhaust operation stop function setting column 15 is set to use the function for stopping the exhaust fan 4. It is. The notification setting column 16 when the exhaust operation is stopped is a column for setting whether or not to notify the remote control device 2 when the exhaust fan 4 is stopped. The exhaust device setting column 17 linked when the exhaust operation is stopped is a column for specifying an exhaust device to be operated when the exhaust blower 4 is stopped, and a device connected to the home communication line 11 and having an exhaust function is provided. A list is displayed based on the information stored in the device information storage unit 121.

  If the notification setting column 16 for notifying the exhaust operation is set to be notified, it is possible to not specify the exhaust device in the exhaust device setting column 17 that is interlocked when the exhaust operation is stopped. When the notification setting column 16 is set not to perform notification, it is essential to specify the device in the exhaust device setting column 17 that is linked when the exhaust operation is stopped. The setting contents of the exhaust operation stop function setting column 15, the notification setting column 16 when exhaust operation is stopped, and the exhaust device setting column 17 linked when the exhaust operation is stopped are stored in the setting information storage unit 106.

FIG. 7 is a flowchart illustrating an example of the operation of the ventilation system. The control unit 104 operates the ventilation system in the first mode (step S101). Based on the measurement result acquired by the sensor information acquisition unit 103 from the outdoor temperature sensor 10, the control unit 104 uses the first threshold temperature T _L and the second threshold value stored in the setting information storage unit 106. it is determined whether the temperature between the temperature _{T H} (step S102). If the air temperature T is not a temperature between the first threshold temperature _{T L} and the second threshold temperature _{T H} (step S102 / No), and continues the operation in the first mode returns to step S101. Set the air temperature T is equal to a temperature between the first threshold temperature _{T L} and the second threshold temperature _{T H} (step S102 / Yes), the control unit 104, which is set in the setting information storage unit 106 It is determined whether or not it is set to use the exhaust operation stop function with reference to the information (step S103). If it is not set to use the exhaust operation stop function (step S103 / No), the process returns to step S101 and the operation in the first mode is continued. If it is set to use the exhaust operation stop function (step S103 / Yes), the control unit 104 refers to the setting information set in the setting information storage unit 106, and the notification setting when the exhaust operation stops is set. It is determined whether it has been done (step S104).

  If the notification setting at the time of exhaust operation stop is not made (step S104 / No), since the exhaust device to be interlocked at the time of exhaust operation stop is always specified, the control unit 104 operates the specified exhaust device ( Step S105). When the notification setting at the time of exhaust operation stop is made (step S104 / Yes), the control unit 104 refers to the setting information set in the setting information storage unit 106, and specifies the exhaust device to be interlocked when the exhaust operation stops. It is confirmed whether it has been done (step S106). If there is a designated exhaust device (step S106 / Yes), the control unit 104 operates the designated exhaust device and sends a message requesting not to stop the designated exhaust device 2 to the remote control device 2. (Step S107). If there is no specified exhaust device (step S106 / No), the remote control device 2 is notified of a message indicating that the exhaust device needs to be operated (step S108).

  After the processing of step S105, step S107, or step S108, the control unit 104 drives the heat exchange ventilator 3 with the exhaust fan 4 stopped, and operates the ventilation system in the second mode (step S109). ).

Based on the measurement result acquired by the sensor information acquisition unit 103 from the outdoor temperature sensor 10, the control unit 104 uses the first threshold temperature T _L and the second threshold value stored in the setting information storage unit 106. it is determined whether the temperature between the temperature _{T H} (step S110). Outside air temperature T is equal to a temperature between the first threshold temperature _{T L} and the second threshold temperature _{T H} (step S110 / Yes), continue to operate in the second mode returns to step S109. Set the air temperature T is not the temperature between the first threshold temperature _{T L} and the second threshold temperature _{T H} (step S110 / No), the control unit 104, which is set in the setting information storage unit 106 With reference to the information, it is determined whether or not the notification setting at the time of exhaust operation stop is made (step S111).

  If the notification setting at the time of exhaust operation stop is not made (step S111 / No), the exhaust device that is interlocked at the time of exhaust operation stop is always specified, so the control unit 104 stops the specified exhaust device ( Step S112). When the notification setting at the time of exhaust operation stop is made (step S111 / Yes), the control unit 104 refers to the setting information set in the setting information storage unit 106 and designates the exhaust device to be linked when the exhaust operation stops. It is confirmed whether it has been done (step S113). If there is a designated exhaust device (step S113 / Yes), the control unit 104 stops the designated exhaust device and sends a message to the remote control device 2 indicating that the designated exhaust device has been stopped. Notification is made (step S114). If there is no designated exhaust device (step S113 / No), the remote control device 2 is notified of a message indicating that the operation of the exhaust device may be stopped (step S115).

  In addition, since the ventilation system which concerns on embodiment has the two heat exchange ventilation apparatuses 3, the setting of an exhaust operation stop function can be performed separately. Further, when the exhaust fan 4 of one heat exchange ventilator 3 is stopped, the other heat exchange ventilator 3 stops the air supply fan 5 and drives only the exhaust fan 4. It can be used as an exhaust device.

  The ventilation system according to the embodiment includes a wireless communication unit 102 having a function of communicating with the remote control device 2 through the home wireless communication network 12 and the public wireless communication network 13, and also includes the sanitary exhaust device 7, the heat exchange ventilation device 3, The exhaust fan 4 is connected to the outdoor temperature sensor 10 and the range hood fan 19, and has an in-home equipment centralized management device 1 that controls switching between operation and stop of the exhaust fan 4 based on the measurement result of the outdoor temperature sensor 10. Is stopped, the sanitary exhaust device 7 and the range hood fan 19 can be automatically operated, or a message prompting the operation of the exhaust device can be notified to the remote control device 2. For this reason, it is possible to reduce power consumption and air-conditioning energy loss while reliably continuing ventilation in the house 200 for 24 hours.

  In the above description, the case where the operation mode of the heat exchange ventilator 3 is switched based on the outside air temperature measured by the outdoor temperature sensor 10 is taken as an example, but the outside air temperature sensor provided in the outdoor unit of the air conditioning equipment 9 If the home equipment centralized management device 1 can acquire information, the operation mode of the heat exchange ventilator 3 can be switched based on the outside air temperature even if the outdoor temperature sensor 10 is omitted.

  In the above explanation, the operation mode of the heat exchange ventilator is switched based on the outside air temperature as an example. However, a sensor for measuring the temperature inside the house is separately provided, and the temperature difference between the house temperature and the outside air temperature. It is also possible to switch the operation mode of the heat exchange ventilator based on the above.
