Claims

[Scope of utility model registration request]

A fresh air introduction passage, a combined air supply passage communicating with the fresh air introduction passage, an exhaust air introduction passage communicating with the combined air supply passage, and an exhaust air discharge passage branched from the waste air introduction passage, A first butterfly valve is provided in a communication passage between the fresh air introduction passage and the combined air supply passage, the first butterfly valve being rotatably supported at the valve end and controlling the supply ratio of fresh air;
A second butterfly valve that is rotatably supported at the valve end and controls the discharge rate of exhaust gas is disposed in a branch path between the exhaust gas introduction passage and the exhaust gas discharge passage, and the first butterfly valve and the second butterfly valve are connected to each other. The butterfly valves are linked so that the exhaust gas discharge rate increases as the fresh air supply rate increases, and an actuator for rotating the valve is attached to either one of the two butterfly valves. Air supply device for waste heat recovery.
