In addition, the server control unit 113 sends advance notification of the heat shock risk to the smartphone 17 before performing control to start the operation of the bathroom heater 13, the dressing room heater 14, and the first intermediate-mounted blower 16a in step S50. You may also send it to Advance notification of heat shock risk notifies users that heat shock is expected to occur in the bathroom 204, dressing room 205, and hallway 203, and also provides information on the bathroom heater 13, dressing room heater 14, and the first intermediate mounting. This notification is for prompting the user to decide whether or not automatic operation with the air blower 16a is necessary. The advance notice of heat shock risk includes information on the outside temperature in the forecast of the acquired weather information 6 on the WEB and information on the temperature difference between the indoor temperature of the living room 201 and the temperature of the hallway 203.

The user confirms the advance notice of risk sent to the smartphone 17, and sends information on whether automatic operation of the bathroom heater 13, changing room heater 14, and first intermediate-mounted fan 16a is necessary from the smartphone 17 to the server. The information is transmitted to the control unit 113. When the server control unit 113 receives necessary information from the smartphone 17 indicating that automatic operation of the bathroom heater 13, the changing room heater 14, and the first intermediate-mounted blower 16a is required, the server control unit 113 controls the bathroom heater 13, the changing room heater 14, and the first intermediate-mounted blower 16a from the smartphone 17 in step S50. Control is performed to start the operation of the heater 13, the dressing room heater 14, and the first intermediate-mounted blower 16a. When the server control unit 113 receives unnecessary information from the smartphone 17 indicating that automatic operation of the bathroom heater 13, the dressing room heater 14, and the first intermediate-mounted blower 16a is unnecessary, the server control unit 113 executes step S50. Terminate processing without doing so.

That is, if the user determines that automatic operation of the bathroom heater 13, the dressing room heater 14, and the first intermediate-mounted blower 16a is unnecessary, the bathroom heater 13, the dressing room heater 14, and the first 1 Automatic operation with the intermediate-mounted blower 16a is not performed.

As a result, family members pay particular attention to each other when undressing and bathing, which requires special care, thereby further increasing the effectiveness of preventing health damage caused by heat shock.

(Second operation example)
Next, other operations of the air conditioning ventilation system 100 will be explained. FIG. 14 is a flowchart illustrating the procedure of the second operation example of the air conditioning ventilation system 100 according to the first embodiment. Here, in winter, the indoor temperature of the bathroom and changing room is low according to the weather information 6 forecast for the area where the indoor equipment of the air conditioning ventilation system 100 is installed, and the so-called heat wave caused by the temperature difference between rooms in the house is explained. We will explain cases in which health damage due to shock is predicted.

The server control unit 113 executes steps S10 to S40 described above.

In step S110, the server control unit 113 determines whether the indoor temperatures of the bathroom 204 and the changing room 205 are equal to or lower than a predetermined first threshold value at the start of the water filling operation of the water heater in the bathroom 204. The first threshold value is a first threshold value used by the server control unit 113 to determine whether or not to operate the bathroom heater 13 and the dressing room heater 14 at the start of the water filling operation of the water heater in the bathroom 204. and is stored in the server control unit 113 in advance. The first threshold is, for example, 18°C. Note that the bathroom 204 and the changing room 205 are adjacent to each other, and the indoor temperatures are the same when heating is not performed. Therefore, the indoor temperature of the bathroom 204 and the indoor temperature of the changing room 205 are set as the first threshold value. compare.

The server control unit 113 determines the indoor temperature of the bathroom 204 based on temperature information that is the measurement result of the temperature sensor 132 of the bathroom heater 13. The server control unit 113 determines the indoor temperature of the changing room 205 based on temperature information that is the measurement result of the temperature sensor 142 of the changing room heater 14 .

If it is determined that the indoor temperatures of the bathroom 204 and the changing room 205 are below the first threshold, the answer is Yes in step S110, and the process proceeds to step S120. If it is determined that the indoor temperatures of the bathroom 204 and the changing room 205 are higher than the first threshold, the answer is No in step S110, and the process proceeds to step S130. In order to prevent the occurrence of heat shock, if at least one of the indoor temperature of the bathroom 204 and the changing room 205 is equal to or lower than the first threshold value, the answer is Yes in step S110, and the process proceeds to step S120.

In step S120, the server control unit 113 controls the bathroom heater 13 and the dressing room heater 14 to start operating. Specifically, the server control unit 113 transmits operation start information instructing the start of operation to the bathroom heating control unit 134 of the bathroom heater 13 and the changing room heating control unit 144 of the changing room heater 14. Upon receiving the operation start information, the bathroom heating control unit 134 operates the bathroom heating unit 131 to operate the bathroom heater 13. Upon receiving the operation start information, the changing room heating control unit 144 operates the changing room heating unit 141 to operate the changing room heater 14.

In step S130, the server control unit 113 determines whether the temperature difference between the indoor temperature of the bathroom 204 and the changing room 205 and the indoor temperature of the living room 201 is greater than or equal to a predetermined second threshold. The second threshold value is a second threshold value used by the server control unit 113 to determine whether or not to operate the bathroom heater 13 and the changing room heater 14 at the start of the water filling operation of the water heater in the bathroom 204. and is stored in the server control unit 113 in advance. The second threshold is, for example, 5°C. The server control unit 113 determines the indoor temperature of the living room 201 based on temperature information that is the measurement result of the indoor temperature sensor 1512 of the indoor unit 151 installed in the living room 201.

If it is determined that the temperature difference between the indoor temperature of the bathroom 204 and the changing room 205 and the indoor temperature of the living room 201 is equal to or greater than the second threshold value, the answer is Yes in step S130, and the process proceeds to step S120. If it is determined that the temperature difference between the indoor temperature of the bathroom 204 and the changing room 205 and the indoor temperature of the living room 201 is lower than the second threshold value, the answer in step S130 is No, and the series of processes ends.

By automatically operating the bathroom heater 13 according to the operation start information, the indoor temperature of the bathroom 204 is improved to be higher than before the automatic operation of the bathroom heater 13 is started during hot water supply, and the indoor temperature of the bathroom 204 is reduced to prevent health damage due to heat shock. By keeping the temperature above the preventive temperature, health damage caused by heat shock to the user can be prevented. This makes it possible to reduce the risk of heat shock caused by forgetting to set the heating operation for the bathroom 204 during bathing, which requires particular attention to the risk of heat shock.

By automatically operating the changing room heater 14 according to the operation start information, the indoor temperature of the changing room 205 is improved to be higher than before the automatic operation of the changing room heater 14 is started during hot water supply, and the indoor temperature of the changing room 205 is heated. By keeping the temperature above the temperature that prevents health damage due to shock, it is possible to prevent health damage due to heat shock to the user. Thereby, it is possible to reduce the risk of heat shock due to forgetting to set the heating operation of the changing room 205 during bathing, which requires special attention to the risk of heat shock.

Further, the server control unit 113 may transmit a preliminary notification of the heat shock risk to the smartphone 17 before controlling the bathroom heater 13 and the changing room heater 14 to start operating in step S130. The advance notice of heat shock risk notifies the user that heat shock is expected to occur in the bathroom 204 and the changing room 205, and also informs the user of the need for automatic operation of the bathroom heater 13 and the changing room heater 14. This is a notice to prompt the user to make a decision.

The user confirms the advance notice of heat shock risk sent to the smartphone 17, and sends information on whether automatic operation of the bathroom heater 13 and the changing room heater 14 is necessary from the smartphone 17 to the server control unit 113. . When the server control unit 113 receives necessary information from the smartphone 17 indicating that automatic operation of the bathroom heater 13 and the dressing room heater 14 is required, the server control unit 113 switches the bathroom heater 13 and the dressing room heater 14 to automatic operation in step S130. Control is performed to start operation with 14. If the server control unit 113 receives unnecessary information indicating that automatic operation of the bathroom heater 13 and the changing room heater 14 is not required from the smartphone 17, the server control unit 113 ends the process without executing step S130.

That is, if the user determines that the automatic operation of the bathroom heater 13 and the dressing room heater 14 is not necessary, the automatic operation of the bathroom heater 13 and the dressing room heater 14 is not performed. Thereby, energy-saving operation of the air conditioning ventilation system 100 is possible.

Further, advance notification of heat shock risk is sent to not only the user's smartphone 17 but also the smartphones of family members. As a result, family members pay particular attention to each other when undressing and bathing, which requires special care, thereby further increasing the effectiveness of preventing health damage caused by heat shock.

(Third operation example)
Next, other operations of the air conditioning ventilation system 100 will be explained. FIG. 15 is a flowchart illustrating the procedure of the third example of operation of the air conditioning ventilation system 100 according to the first embodiment. Here, a case will be described in which bad weather such as a typhoon, heavy rain, heavy snow, or fog is predicted in the forecast of the weather information 6 on the web. If the air supply operation of the heat exchange ventilation system 12 continues in weather conditions such as typhoons, heavy rain, heavy snow, or fog, water may enter the third air supply duct 303 and the inside of the heat exchange ventilation system 12 and the third air supply Water condensation occurs inside the air duct 303 and the heat exchange ventilation device 12, causing problems such as water dripping or high humidity air flowing into the living room 201 and the Japanese-style room 202.

Therefore, if there is a forecast of bad weather in the weather information 6 on the web, the server control unit 113 suppresses the occurrence of problems such as dripping of water or inflow of high-humidity air into the living room 201 and Japanese-style room 202. Alternatively, the heat exchange ventilation device 12 is controlled in a water intrusion prevention mode to prevent water intrusion. The water intrusion prevention mode is an operation mode in which the air supply operation in the heat exchange ventilation device 12 is stopped or suppressed by stopping or suppressing the output of the air supply blower 122 of the heat exchange ventilation device 12. Furthermore, the water intrusion prevention mode can be referred to as an operation mode in which the air volume of the air supply blower 122 in the heat exchange ventilation device 12 is stopped or suppressed.

In a state where the ventilation device control unit 126 of the heat exchange ventilation device 12 is controlling the operation of the heat exchange ventilation device 12 in the normal operation mode, the server control unit 113 performs step S20 and step S30 described above. The normal operation mode is an operation mode that operates with ventilation 24 hours a day.

In step S210, the server control unit 113 determines whether or not there is a forecast of poor weather in the forecast of the acquired weather information 6 on the WEB. A forecast of bad weather is a forecast that predicts the occurrence of at least one of a typhoon, heavy rain, heavy snow, and fog. If it is determined that there is a forecast of poor weather in the weather information 6 on the web, the answer is Yes in step S210, and the process proceeds to step S220. If it is determined that there is no forecast of bad weather in the weather information 6 on the web, the answer to step S210 is No, and the process proceeds to step S250.

In step S220, the server control unit 113 transmits water intrusion prevention mode control instruction information to the ventilation device control unit 126 of the heat exchange ventilation device 12.

In step S230, upon receiving the water intrusion prevention mode control instruction information, the ventilation device control unit 126 performs control to increase the ventilation airflow rate from the ventilation airflow rate in the currently implemented 24-hour ventilation. Specifically, the ventilation system control unit 126 changes the output of the air supply blower 122 and the exhaust air blower 123 to the output of the air supply blower 122 and the exhaust air blower 123 in the currently implemented 24-hour ventilation. Increase the ventilation air volume. In this case, the output of the air supply blower 122 and the output of the exhaust air blower 123 are the same, and the air volume of the air supply fan 122 and the air volume of the exhaust air blower 123 are the same.

Information on the output to be increased here is stored in advance in the ventilator control unit 126. The output to be increased can be set and changed to arbitrary conditions from the smartphone 17 by the user. Note that information on the output to be increased may be stored in the server control unit 113 and transmitted from the server control unit 113 to the ventilation device control unit 126 together with control instruction information for the water intrusion prevention mode.

After the heat exchange ventilation device 12 performs the ventilation operation with the ventilation air volume increased as described above for a predetermined operation time, the process proceeds to step S240.

In step S240, the ventilation device control unit 126 stops the air supply operation of the air supply blower 122 in the heat exchange ventilation device 12 by stopping the output of the air supply blower 122, or the output of the air supply blower 122. By suppressing this, the air volume during the air supply operation of the air supply blower 122 in the heat exchange ventilation device 12 is suppressed. When suppressing the air volume during the air supply operation, the ventilator control unit 126 suppresses the air volume during the air supply operation to be smaller than the 24-hour ventilation before increasing the ventilation air volume in step S230.

Here, information on whether to stop the air supply operation or to suppress the air volume of the air supply operation is stored in advance in the ventilation device control unit 126. Further, information on the suppression output, which is the output of the air supply blower 122 when suppressing the output of the air supply blower 122, is stored in advance in the ventilation device control unit 126. Note that the information on the suppression output of the air supply blower 122 may be stored in the server control unit 113 and transmitted from the server control unit 113 to the ventilator control unit 126 together with the control instruction information for the water intrusion prevention mode.

Then, after a predetermined time has elapsed after step S240, the process returns to step S30.

In step S250, the server control unit 113 transmits control instruction information for the normal operation mode to the ventilation device control unit 126 of the heat exchange ventilation device 12. When the ventilation device control unit 126 of the heat exchange ventilation device 12 receives control instruction information for the normal operation mode, it does not change the operation control.

After step S250, the process returns to step S30 after a predetermined period of time has elapsed.

By executing the above-described process, the air conditioning ventilation system 100 does not actively take outdoor rainwater and high-humidity air into the third air supply duct 303 and the heat exchange ventilation device 12. As a result, the air conditioning ventilation system 100 can prevent water dripping or high humidity air from entering the living room 201 and the Japanese-style room 202, and prevent the living room 201 and the Japanese-style room 202 from entering the living room 201 and the Japanese-style room 202 during bad weather such as typhoons, heavy rain, heavy snow, and fog. Improved comfort can be achieved.

In addition, the air conditioning ventilation system 100 can suppress the intrusion of rainwater and high-humidity air into the third air supply duct 303 and the heat exchange ventilation device 12. The occurrence of malfunctions in the air supply duct 303 and the heat exchange ventilation device 12 can be suppressed.

The air conditioning ventilation system 100 increases the ventilation air volume in step S230 before stopping the air supply operation or suppressing the air volume of the air supply operation in step S240, thereby increasing the ventilation air volume in advance in the living room 201 and The carbon dioxide concentration in the Japanese-style room 202 is reduced in advance. As a result, it is possible to suppress deterioration of the indoor environment due to an increase in carbon dioxide concentration in the living room 201 and the Japanese-style room 202 when the air supply operation is stopped or the air volume of the air supply operation is suppressed in step S240. It is possible to suppress a decrease in the comfort of 202.

Note that, instead of transmitting the water intrusion prevention mode control instruction information to the ventilation device control section 126 of the heat exchange ventilation device 12, the server control section 113 transmits the above-mentioned air volume increase instruction information that instructs to increase the ventilation air volume to the ventilation device. Output stop instruction information that instructs to stop the output of the air supply blower 122 or output suppression instruction information that instructs to suppress the output of the air supply blower 122 is transmitted to the control unit 126 after a predetermined time has elapsed. It may also be transmitted to the ventilator control unit 126.

(Fourth operation example)
Next, other operations of the air conditioning ventilation system 100 will be explained. FIG. 16 is a flowchart illustrating the procedure of the fourth example of operation of the air conditioning ventilation system 100 according to the first embodiment. For example, in early spring, the amount of air pollutants such as pollen, PM2.5, and yellow sand may increase. Here, a case will be described in which the forecast of weather information 6 on the web predicts the scattering of air pollutants such as pollen, PM2.5, and yellow dust.

In a state where the ventilation device control unit 126 of the heat exchange ventilation device 12 is controlling the operation of the heat exchange ventilation device 12 in the normal operation mode, the server control unit 113 performs step S20 and step S30 described above.

In step S310, the server control unit 113 determines whether the acquired weather information 6 on the web includes a forecast of air pollutant dispersion. The air pollutant scattering forecast is a forecast that predicts the air pollutant scattering. If it is determined that the forecast in the weather information 6 on the web includes a forecast of air pollutant scattering, the answer is Yes in step S310, and the process proceeds to step S320. If it is determined that there is no forecast of air pollutant scattering in the forecast of the weather information 6 on the web, the answer is No in step S310, and the process proceeds to step S350.

In step S<b>320 , the server control unit 113 transmits information on the forecast of air pollutant scattering in the forecast of the acquired weather information 6 on the WEB to the ventilation system control unit 126 of the heat exchange ventilation system 12 .

In step S330, upon receiving the information on the air pollutant scattering forecast, the ventilator control unit 126 of the heat exchange ventilation apparatus 12 determines that the air pollutant concentration indicated in the air pollutant scattering forecast is determined in advance. It is determined whether or not it is equal to or higher than a third threshold value. The third threshold is a threshold for the ventilation system control unit 126 to determine whether or not to control the operation of the heat exchange ventilation system 12 in the air pollutant infiltration prevention mode, and is determined in advance for each type of air pollutant. and is stored in the ventilator control unit 126.

If it is determined that the concentration of air pollutants in the air pollutant scattering forecast is equal to or higher than the third threshold, the answer is Yes in step S330, and the process proceeds to step S340. If it is determined that the concentration of air pollutants in the air pollutant scattering forecast is less than the predetermined third threshold, the result is No in step S330, and after the predetermined time has elapsed, the process returns to step S30. .

In step S340, the ventilator control unit 126 controls the operation of the heat exchange ventilator 12 in the air pollutant intrusion prevention mode. That is, the ventilation device control unit 126 adjusts the output of the supply air blower 122 and the output of the exhaust air blower 123. Specifically, the ventilation system control unit 126 performs control to increase the supply air volume Q _SA by a predetermined air volume with respect to the exhaust air volume Q _RA , that is, performs control such that the supply air volume Q _SA >exhaust air volume Q _RA . .

Note that the supply air volume Q _SA and exhaust air volume Q _RA in the air pollutant intrusion prevention mode are defined as the supply air volume Q _SA > ventilation with respect to the ventilation volume Q ₁ required in the normal operation mode of the heat exchange ventilation system 12. The amount Q ₁ may be set, or the exhaust air volume Q _RA < the ventilation amount Q ₁ . Note that in the normal operation mode, the supply air volume _QSA , the exhaust air volume _QRA , and the ventilation volume _Q1 are equal.

By executing the above-described process, the indoor space inside the house has a positive pressure, and it is possible to prevent air pollutants from entering through the gaps in the building of the house. As a result, the air conditioning ventilation system 100 can prevent air pollutants from entering the interior of the house, and improve the comfort of the interior environment of the house when air pollutants such as pollen, PM2.5, and yellow dust are scattered. can.

In addition, the air conditioning ventilation system 100 uses the forecast of weather information 6 obtained from the web to detect air pollution from gaps in the building without using a dedicated sensor when the scattering of air pollutants is predicted. It is possible to prevent contaminants from entering. As a result, it is possible to reduce the number of sensors mounted on the in-building equipment of the air conditioning ventilation system 100, simplify the configuration of the in-building equipment, and suppress an increase in the product cost of the in-building equipment. In particular, the detection of PM2.5 whose main particle size range is 0.5 μm or more and 1.0 μm or less requires a more precise optical sensor than sensors that detect other air pollutants, which increases product costs. has a large suppressive effect.

In addition, the air conditioning ventilation system 100 can prepare the indoor environment in advance by using forecast information as a forecast of the weather information 6 obtained from the web. It becomes possible to minimize the negative effects caused by ventilation suppression. Further, in addition to the forecast of the weather information 6, the current outdoor weather information 6 may be used. By using the current outdoor weather information 6, control to improve the indoor environment can be started immediately. By using the current outdoor weather information 6, it is possible to immediately respond to changes in the outside temperature.

Further, after step S330, the server control unit 113 may send a recommendation notification recommending that the user not to open the window to the smartphone 17 together with the forecast information of the weather information 6. This can prevent air pollutants from entering the house through the windows.

In addition, if it is predicted that the amount of air pollutants scattered over a predetermined period will increase based on the forecast of the weather information 6 obtained from the web, the server control unit 113 temporarily suspends the high-performance dust removal filter. A recommendation notification recommending use may be sent to the smartphone 17. Thereby, the user can be encouraged to maintain the indoor air environment. If you continue to use a high-performance dust removal filter all year round, the life of the high-performance dust removal filter will be shortened, resulting in early performance deterioration and filter replacement, so use the high-performance dust removal filter only when the concentration of air pollutants is high. It is preferable to do so.

In addition, in order to suppress air pollutants from entering the room, in ventilation equipment other than the heat exchange ventilation device 12 that does not have a filter, such as the bathroom heater 13, the exhaust air volume during ventilation operation may be suppressed or It will be stopped.

(Fifth operation example)
FIG. 17 is a flowchart illustrating the procedure of the fifth operation example of the air conditioning ventilation system according to the first embodiment. Here, a case will be described in which it is assumed that the daytime outdoor temperature exceeds a predetermined threshold value in the summer.

In step S410, the server control unit 113 determines whether the daytime outdoor temperature is predicted to exceed a predetermined fourth threshold based on the acquired forecast of the weather information 6 on the WEB. If it is determined that the daytime outdoor temperature exceeds the predetermined fourth threshold, the answer is Yes in step S410, and the process proceeds to step S420. If it is determined that the daytime outdoor temperature does not exceed the predetermined fourth threshold, the result is No in step S410, and the server control unit 113 ends the series of processes.

In step S420, the server control unit 113 increases the ventilation air volume of the heat exchange ventilation device 12 in advance compared to when operating in the normal operation mode under conditions such as early morning when indoor temperature>outdoor temperature holds, thereby increasing the indoor temperature. Lower it. Thereby, the indoor temperature can be lowered in advance before the indoor temperature exceeds the fourth threshold value, and the air conditioning load on the air conditioner 15 can be reduced.

(Sixth operation example)
FIG. 18 is a flowchart illustrating the procedure of the sixth operation example of the air conditioning ventilation system according to the first embodiment. Here, a case will be described in which it is assumed that the outdoor temperature at night and early in the morning in winter falls below a predetermined threshold.

In step S510, the server control unit 113 determines whether the outdoor temperature at night and early in the morning is predicted to fall below a predetermined fifth threshold, based on the acquired forecast of the weather information 6 on the WEB. do. If it is determined that the outdoor temperature at night and early in the morning is below the predetermined fifth threshold, the answer is Yes in step S510, and the process proceeds to step S520. If it is determined that the outdoor temperature at night and in the early morning does not fall below the predetermined fifth threshold, the result in step S510 is No, and the server control unit 113 ends the series of processes.

In step S520, the server control unit 113 raises the indoor temperature by increasing the ventilation air volume of the heat exchange ventilation device 12 in advance compared to when operating in the normal operation mode under the condition that the indoor temperature during the daytime < the outdoor temperature holds. I'll keep it. Thereby, the indoor temperature can be raised in advance before the indoor temperature falls below the fifth threshold value, and the air conditioning load on the air conditioner 15 can be reduced. Note that when increasing the ventilation air volume, bypass ventilation in which the exhaust flow does not pass through the heat exchanger 121 is also effective.
