ーを余分に消費する事はない。Also, during the air-conditioning ventilation operation, for example, when the consumer leaves the third room a3, the operation switch 37 of the room a3 is operated to input the operation stop command, and the operation stop command is input, as shown in FIG. As shown, only the air-conditioning flow rate adjusting mechanism 31 provided on the side of the sub duct 19 communicating with the third room a3 is closed. As a result, only the ventilation air is supplied from the opening 5 to the third room a3 via the flow control mechanism 33 for ventilation in the open state. At this time, in the third room a3, although the temperature is lower than the air-conditioning air flowing through the main air-conditioning duct 13, the temperature is higher than the outside air, and the air (ventilation air) that is dryer than the indoor humidity flows. . Thereby, the third room a3 can maintain a state where the humidity is lower than the other rooms and the temperature is higher than the outside air. Now, assuming that the outside air temperature is 0 ° C., the indoor temperature is 20 ° C., 40%, and the efficiency of the sensible heat exchange unit 29 is 70%, the ventilation air is warmed to 14 ° C., flows into the room, warms the room and decreases several degrees, for example, by 10 ° C. ° C, and flows out to the common space (corridor) through the ventilation hole 7 of the door 9. The room temperature of the third room a3 is about 12 ° C., and the temperature of the window whose temperature drops the most is about 8 ° C. Since the dew point temperature of the indoor air is 5.5 ° C., no dew condensation occurs on the windows. In addition, there is no need to introduce air conditioning air to prevent dew condensation, and no extra energy is consumed.

Since the room temperature 3 greatly exceeds the set temperature under the influence of the solar radiation, the air-conditioning flow control mechanisms 31 communicating with the second room a2 and the third room a3 are closed, and the ventilation main duct 17 is closed. Only the supplied ventilation air is used for the second
To the room a2 and the third room a3. As for the flow rate of the ventilation air, the temperature of the room is constantly monitored, and the opening degree of the flow rate adjustment mechanism 33 for ventilation is controlled so that the room temperature matches the set temperature to increase the flow rate.

In this case, as in the case of the heating, the air-conditioning flow rate adjusting mechanism 31 leading to the room having the temperature lower than the set temperature is also provided. At the same time, the ventilation may be increased by adjusting the opening of the flow rate adjusting mechanism 33 for ventilation so that the room temperature of the room coincides with the set temperature.

For example, as shown in FIG. 6, the second room a2 and the third room a3 face south and are easily affected by solar radiation. Room temperature sensor 43 is a
2, the room temperature of a3 is constantly monitored, and when a state in which the signal (room temperature information) detected by the room temperature sensor 43 exceeds the set temperature for a predetermined time continues, the control unit 61 sets the flow rate for ventilation to each of the rooms a2 and a3. The adjusting mechanisms 33 are closed. Further, at the same time as opening the air conditioning flow control mechanism 31 communicating with each of the rooms a2 and a3, the rotation of the fan of the blower 59 is reversed, and the room air is sucked from the opening 5 into the duct passage. The air flowing from the opening 5 is supplied to the sub duct 19 and the flow control mechanism 3.
1. The air is sent to the air conditioning main duct 13, where it is combined with the air conditioning air warmed by the indoor air conditioner 11, and supplied to the first room a1 and the fourth room a4 that require heating.
The amount of indoor air sucked into the sub duct 19 is determined based on a signal (room temperature information) from the room temperature sensor 43.
1, 33 and the blower 59 are controlled by the control unit 61, and the room temperature of the room is maintained at the set temperature.

Then, the room becomes too cold due to the influence of the sun and the room temperature falls below the set temperature. The surplus energy is reversed by reversing the rotation of the fan of the blower 59, and the cool air flowing through the opening 5 is sent to the sub duct 19, the flow rate adjusting mechanism 31, and the main air conditioning duct 13, where the indoor air conditioner 1

Therefore, the flow rate passing through the sub duct is increased, and quick temperature adjustment can be performed in a short time.

にした第10の実施形態について説明する。(Tenth Embodiment) When a consumer leaves a house for traveling, going out, or the like, the whole building air-conditioning ventilation system may be stopped. At this time, if all the devices are stopped at the same time, dew condensation occurs due to the water vapor remaining in the house and the temperature drop in the room. A tenth embodiment that prevents the occurrence of condensation will be described.
【0093】尚、構成要素は、図1〜図6と同一であり
詳細な説明は省略する。The components are the same as those in FIGS. 1 to 6, and a detailed description is omitted.

せる。In FIG. 1, when the user is away from the house, the user operates the operation switch 37 to input a whole building stop command for stopping the whole building air conditioning and ventilation system. The control unit 35 that has received the command to stop the whole building stops only the sensible heat exchange air fan 15 with a delay for a predetermined time, but sequentially stops the devices as follows.

Close. Air conditioning to each room is stopped. At this time, the flow control mechanism 33 for ventilation remains open, and only the ventilation air is supplied to each room. And sensible heat exchange fan 1
5 is stopped after a certain time delay.

い。As a result, even if the indoor air conditioner 11 is stopped, the sensible heat exchange air fan 15 continues to operate for a certain period of time. And is discharged outside. For this reason, after the operation is stopped, each room a1, a2, a3, a
4, since the ventilation air heated and dried by the sensible heat exchange air unit 29 is supplied for a certain period of time, no dew condensation occurs even if the room temperature drops after the sensible heat exchange air unit 29 stops.

For this reason, it is preferable to set the delay time required for the prevention of dew condensation by the time obtained by dividing the air volume (volume) of the house by the ventilation volume of the sensible heat exchange air fan 15.

Therefore, it is preferable to provide a display device 49 such as a display lamp near the opening 5 as shown in FIG.

く部屋の結露防止を図ることができる。As described above, according to the air conditioning and ventilation system for a building according to the present invention, the fresh and dry air introduced from the outside air is heated by the heat energy recovered from the exhausted indoor air, and the air is heated. Since it is used for air-conditioning ventilation of the room in which the air-conditioning operation is stopped, it is possible to prevent dew condensation in the room without consuming extra energy.
