Abstract

PURPOSE: To prevent the propagation of noises of a fan in an air-conditioner by discharging cold air in a cold air duct through a gas-permeable resistance element.
CONSTITUTION: The cold air in a cold air duct 6 flows through cold air inlet ports 20 provided in an upper portion of a mount 16, and then through a gas-permeable resistance element 18 and a gas-permeable support 19 into a passenger room. This allows the flow rate of the cold air passing through the inlet ports 20 and air noise to be reduced. Since the gas-permeable resistance element 18 has a sound-absorbing capability, the noise of a fan in an air-conditioner can also be reduced.
