Abstract

PURPOSE: To prevent the generation of rustling noise at the back of a heat exchanger by disposing a baffle plate in a space facing the heat exchanger at the outlet of an air feed duct which forms an air feed passage.
CONSTITUTION: An air feed fan 4 and an exhaust fan rotate driven by motors and an air flow through an air feed passage and an exhaust passage is generated. A heat exchanger 12 transfers the heat quantity of the exhaust air flow to the fed air flow while rotating at a low speed. An air flow A generated by the air feed fan 4 is blown out towards the heat exchanger 12 along the spiral form of an air feed duct 5. Since the heat eschanger 12 rotates as shown by an arrow mark B although at a low speed, it gives the interference of the rotating direction to the air flow A, causing karman vortex C and generating rustling noise, but in the present invention, a baffle plate 18 has been disposed at the outlet of the air feed duct 5, so that the Karman vortex C can be removed positively.
