Alternatively, when it is stopped or operated, its operation notch, for example, operation information such as “strong” and “weak” is collected by the operation information collecting unit 16, and the exhaust air volume at the operation notch of each exhaust device is registered in advance. Based on the collected operation information, referring to the exhaust air volume storage unit 17
The amount of air that can be exhausted from the room 8 is calculated and output to the introduced outside air amount determination unit 18. This output air volume is supplied to the air supply units 1a, 1b, 1 by the introduced outside air volume determination unit 18.
It is divided by the number of installed c (three units in the present embodiment) to determine the required introduced outside air amount per unit, and the determined required outside air amount is output to the outside air amount comparison unit 19. On the other hand, the wind speed sensors 5a, 5b, 5c are used to supply the intake air passages 4a, 4b

Since it introduces the same amount of outside air as in the case of a new or existing housing in an apartment house, mechanical ventilation of the simultaneous air supply / exhaust system can be easily applied. The disturbance of the environment can be suppressed. Also, when the outside wind is strong, the outside air introduction fan 25
Since the operating loads of a, 25b, and 25c can be reduced, an energy saving effect can be expected compared to general mechanical ventilation of the simultaneous air supply / exhaust system.

Although the fan inverters 23a, 23b and 23c are used as the air volume adjusting means here, any means may be used as long as it can change the air volume of the outside air introducing fans 25a, 25b and 25c. Needless to say, the same effect can be obtained by using the air volume adjusting damper.

Next, a second embodiment of the present invention will be described with reference to FIGS. The same parts as those in the first embodiment are designated by the same reference numerals, and detailed description thereof will be omitted.

As shown in the figure, the control unit B29 is composed of a numerical keyboard, a microcomputer and a fan inverter, and a user interface 30 through which a builder and a resident can input and change the settings numerically.

With the above configuration, the operation will be described below. In the user interface 30, the floor area (m ² ) inside the dwelling unit and the standard ceiling height (m) that are the unique information of the dwelling unit
When is input, this input value is always output to the exhaust amount calculation unit 31. The constant exhaust volume calculation unit 31 calculates the room volume (m ³ ) of the dwelling unit from the product of the floor area of the dwelling unit and the standard ceiling height, and needs the air volume that can replace all the air in this dwelling unit room volume in 2 hours. When the room volume of the dwelling unit is divided by 2 as the ventilation volume, the required exhaust volume is calculated, and the continuous operation control unit 3
2 (fan inverter). Bathroom ventilation fan 11
However, the rotation speed of the motor (not shown) of the bathroom ventilation fan 11 is controlled by the constant operation control unit 32 (fan inverter) so that the constant exhaust operation can be performed with the required displacement calculated by the constant exhaust amount calculation unit 31. It will be.

Next, the constant displacement calculation unit 31 calculates,
The details of the calculation method of the air volume required for constant ventilation will be described. As for the induction level for ventilation, the required ventilation of a house is 18 m ³ / hour / person, and assuming that 5 people live in each unit, the required ventilation will be 90 m ³ / hour. In addition, the average floor area of a dwelling unit in an apartment is generally about 75
Since it is m ² , assuming that the standard ceiling height is 2.4 m, the room volume of the dwelling unit is 180 m ³ . At this time, when the required ventilation volume of 90 m ³ / hour is divided by the room volume of 180 m ³ of the dwelling unit, the ventilation frequency (times / hour) as an index of how many times the air in the dwelling unit changes per hour is 0.5 times / hour. Desired. Therefore, the constant exhaust gas amount calculation unit 31 used in this embodiment can calculate the necessary exhaust gas amount for ensuring the ventilation frequency of 0.5 times / hour.

In the method for calculating the air volume required for constant ventilation, which is calculated by the constant exhaust volume calculation unit 31 in this embodiment, the exhaust volume is calculated by setting the ventilation frequency (times / hour) to 0.5 times / hour. However, since the natural ventilation frequency is about 0.1 times / hour in the dwelling unit of the apartment house with high airtightness,
The same effect can be obtained even if the exhaust volume is calculated within the range of ventilation times (times / hour) of about 0.3 times / hour to 0.5 times / hour.

In this embodiment, the fan inverter is used as the continuous operation control means, but the continuous operation is performed by selecting the closest notch which is calculated by the constant exhaust gas amount calculation unit 31 and has the air volume required for constant ventilation. Alternatively, notch operation control may be performed.

In the static pressure comparison unit 36, the static pressure value on the outdoor balcony 2 side or the entrance 3 side, whichever is higher,
The static pressure value in the room 8 is compared, and the comparison result is output to the differential pressure information transmission unit 37, and the room 8 is compared with the static pressure value of the outdoor balcony 2 side or the entrance 3 side, whichever is higher. When the static pressure value is low, that is, when the room 8 has a negative pressure, the amount of outside air introduced is increased, and the room 8 is kept more than the static pressure values on the outdoor balcony 2 side and the entrance 3 side. Thus, the outside air introduction amount determination unit 18 is controlled.

As described above, according to the ventilation system for a housing complex of the third embodiment of the present invention, the static pressure in the room 8 is kept slightly high even if the pressure difference between the room 8 and the outdoors occurs due to some influence.
