A fan assembly comprising:
- an air duct;
- an evaporator coil cover;
- a radial fan mounted onto the evaporator coil cover and disposed between the air duct and the evaporator coil cover;
- wherein the air duct includes a ring portion which interlocks with the evaporator coil cover around the radial fan;
- wherein the evaporator coil cover comprises three darts positioned substantially uniformly around the radial fan position;
- three grommets, each grommet having a central opening configured to fit over a dart, each grommet having a circumferential ridge configured to interlock with a lower rim or the radial fan.
A method of reducing noise in a refrigeration appliance comprising the steps of:
- providing a radial evaporator fan;
- housing the radial evaporator fan in a mounting assembly which comprises an air duct and an evaporator coil cover, wherein the air duct includes a ring portion which interlocks with the evaporator coil cover around the radial fan;
- wherein the evaporator coil cover comprises three integrally formed darts positioned substantially uniformly around the radial fan position and wherein the radial fan is attached to the evaporator coil cover by way of three rubber grommets, each grommet having a central opening configured to fit over a dart, each grommet having a circumferential ridge configured to interlock with a lower rim or the radial fan, wherein each dart is positioned at an angle of from 5 to 30 degrees with respect to a normal to an outer circumference of the radial fan.
