Abstract

PURPOSE: To prevent a damper from generating an impact sound at the time of switchover by a construction wherein the main shaft of a rotary type buffer having the characteristic that a necessary rotational torque is large when a speed of rotation is high, and small when the speed is low, is joined directly or indirectly to the main shaft of a damper motor, in equipment for switching over total enthalpy heat exchange ventilation and ordinary ventilation. CONSTITUTION: When the power supply of a damper motor is cut in the case of switchover from an ordinary ventilation operation to a total enthalpy heat exchange ventilation operation, a damper is to return rapidly due to an elastic tension of a spring, a wire 13 one end of which is fixed to the damper is pulled and a main shaft 14 is to rotate at a high speed through the intermediary of a pulley 15. The main shaft 14 is joined to the main shaft 17 of a rotary type buffer 16 through the intermediary of the pulley 15 and this buffer has the characteristic that a necessary rotational torque is large when a speed of rotation is high, and small when the speed is low. When the power supply of the damper motor 10 is cut and the main shaft 14 is to rotate at a high speed, therefore, the buffer so functions as to suppress this rotation, the damper rotates at a low speed even when the power supply breaks off and an impact sound is not generated.

In the total heat exchanger having the above structure, when the exhaust fan 1 and the air supply fan 2 are simultaneously activated, the outside air inlet 4
The outside air is taken in from the inside, passes through the total heat exchange element 3, and is supplied to the room through the indoor air supply port 5 (see the broken line A in FIG. 3). On the other hand, indoor air is taken in through the indoor exhaust port 6, passes through the total heat exchange element 3, and is exhausted outdoors through the outdoor exhaust port 7 (see the broken line B in FIG. 3). Therefore, in the total heat exchange element 3, heat exchange is performed between the outside air and the indoor air, and the air conditioning load can be reduced to ventilate the room.

When the room is cooled or heated as described above, heat exchange is performed between the outside air and the room air to reduce the air conditioning load, but the room is cooled or heated. In the non-season (interim period), such heat exchange becomes unnecessary, and it is rather desirable to cool the room with outside air.
In this case, the damper motor 10 is started and the wire 13
Is wound up, and the damper 9 is rotated against the spring 11 to the position indicated by the chain double-dashed line (the position indicated by 9 ') to open the damper 9.

When the exhaust fan 1 and the air supply fan 2 are started in this state, the indoor air taken in through the indoor exhaust port 6 flows as shown by a two-dot chain line curve B'and passes through the total heat exchange element 3. Instead, it is exhausted to the outside through the outdoor exhaust port 7. Therefore, heat is not exchanged in the total heat exchange element 3 between the outside air sucked from the outside air introduction port 4 and the room air, and the outside air is directly supplied to the room through the indoor air supply port 5. That is, normal ventilation is performed.

According to the present invention, as described above, the main shaft of the damper motor is directly or indirectly connected to the main shaft of the rotary shock absorber, which has small characteristics when the required rotation torque is large when the rotation speed is high and low when the rotation speed is high. When switching from normal ventilation to total heat exchange ventilation or from total heat exchange ventilation to normal ventilation, turn off the power of the damper motor and try to rotate the damper at high speed by applying a sudden turning force due to the elastic force of the elastic body. However, since the rotary shock absorber suppresses the rotation of the main shaft of the damper motor, the damper does not rotate at high speed. Therefore, the collision (impact sound) due to the damper hitting the main body unit 8 is not generated.

The operation of the total heat exchanger having the damper motor section having the above structure is as described above. When switching from the normal ventilation operation to the total heat exchange ventilation operation, when the damper motor 10 is turned off, the damper 9 causes the spring 1 to move.
