Description of the Related Art In a conventional air-conditioning ventilator, the following structure is known as a technique for strongly ventilating a room having a high carbon dioxide concentration. That is, a sensor for detecting the concentration of carbon dioxide in the room is provided, a damper is provided in the ventilation passage of the ventilation fan, and the control means adjusts the opening degree of the damper according to the detection signal of the sensor.

A schematic diagram indicating the operating state of the fan, reference numeral P in FIG. 2 shows the pressure, reference numeral Q is a flow rate, symbol S represents the performance curve of the blower, reference numeral R 1 · R 2 blowing paths Shows flow resistance.

て、室内が適度に換気される。In a normal operation state in which the sensor detects that the carbon dioxide concentration is lower than a set value (for example, 1000 ppm which is the environmental standard value of the living room), the control means reduces the opening degree of the damper. To increase the flow resistance of the air passage. As a result, the blower is operated at a small flow rate Q 1 corresponding to the intersection of the large flow resistance R 1 and the performance curve S, and the room is appropriately ventilated.

The control means enlarges the opening of the damper to reduce the flow resistance of the air passage. As a result, the blower is operated with a large flow rate Q 2 corresponding to the intersection of the small flow resistance R 2 and the performance curve S, and the room is strongly ventilated. When the carbon dioxide concentration in the room becomes lower than the set value due to the strong ventilation, the opening degree of the damper is reduced again. Then, in this normal operation state, as described above, the large flow resistance R
The blower is operated at a small flow rate Q 1 corresponding to the intersection of 1 and the performance curve S.

In the above-described normal operation state with a small flow rate, it is necessary to reduce the opening degree of the damper to increase the flow resistance of the blower path, so that the power loss of the blower is large. Further, since it is necessary to provide a space for installing the damper in the air passage of the blower, the size of the ventilation device is increased by that space. Also, if the above-mentioned forced ventilation of carbon dioxide is continued when the humidity of the outside air is low, such as in winter,
Since the humidity of the room is rapidly reduced by the outside air taken in, the comfort of the room is impaired.

きる。The present invention has the following effects because it is configured and operates as described above. Since the normal operation state with a small flow rate can be obtained by switching the rotation state of the blower, it is not necessary to increase the flow resistance of the blower path in the normal operation state, and the power loss of the blower can be reduced. Moreover, since it is not necessary to install the damper of the conventional example in the air passage of the blower, the installation space can be omitted, and the ventilator can be made smaller by that amount. Further, the outside air taken into the total heat exchanger from the outside is sufficiently humidified in advance by the humidified return air, and subsequently strongly humidified by the humidifier.

置。1. The air in the room (A) is passed through a return path (6), a first path (2a) of the total heat exchanger (2) and an exhaust path (7) in this order to the outside of the room.
A first blower (3) for discharging to (B) is provided, and the air outside the room (B) is connected to the outside air passage (8) and the total heat exchanger (2).
Through the second passage (2b) and the air supply passage (9) in order
A second blower (4) for supplying to (A) is provided, and at least the first blower (3) of the two blowers (3) and (4) is in a low flow rate rotation state (L) and a high flow rate rotation state. (H) and at least two rotation states can be switched, and a sensor (17) for detecting the carbon dioxide concentration in the air in the room (A) is provided, and the detection signal of the sensor (17) is The control means (11) for inputting is provided, and the control means (11) detects the carbon dioxide gas concentration is lower than a set value by the sensor (17), and thus the first blower. While switching (3) to the above-mentioned low flow rate rotation state (L), the same as above is based on the fact that the same sensor (17) detects that the carbon dioxide concentration in the same is above the set value. The first blower (3) is configured to be switchable to the high flow rate rotation state (H), and the air supply passage is An air-conditioning ventilator characterized in that a humidifier (13) is arranged across (9) and the return air passage (6).
