FIELD: transport engineering; ventilating, heating, air conditioning.
SUBSTANCE: invention is aimed at creating comfort conditions in saloons of vehicles. Proposed heating-and-ventilating noise-damping device has fan 1 delivering air through delivery channel 2 in to heater housing 3 provided with recess 4 in wall opposite to delivery channel, of depth equal to thickness of noise-damping gasket 5 which is fitted in recess. Said gasket 5 is made of foamed material and is provided with glue layer for connection with wall of housing 3, and outer, layer protecting from action of surrounding medium. Noise-damping gasket 5 is arranged in zone of impact of air flow from fan 1 striking against walls of heater housing 3.
EFFECT: improved noise-damping properties of device.
