US Patent:

49446541, Jul 31, 1990

Filed:

May 15, 1989

Appl. No.:

7/351597

Inventors:

Mark R. Hogan - Manlius NY

Assignee:

Carrier Corporation - Syracuse NY

International Classification:

F04D 2944

US Classification:

4152112

Abstract:

A split scroll diffuses and directs air upwards from the circumference of a forwardly-curved centrifugal fan to a discharge plane to one side of the fan. The scroll has a first monotonically increasing curved wall that extends from a cutoff point near the circumference of the rotor, in the direction of rotation, to the discharge plane. A second monotonically increasing curved wall extends in the opposite direction from the cutoff point up to the discharge plane. The first and second curved walls are mirror images of one another taken at the plane corresponding to the air flow tangent that passes through the cutoff point. A curved cover above the fan at the exit plane blocks line of sight noise from radiating directly from the fan rotor into the work space or living space.

International Classification:

F01D 904

US Classification:

415223

Abstract:

A fan orifice structure and cover intended for use in conjunction with the outside enclosure, usually containing the outside heat exchanger and compressor, of an air conditioning system. The orifice features relatively complex contours that enhance fan efficiency and reduce radiated noise. The cover in which the orifice structure is incorporated can include a plurality of fan motor support brackets and a motor mount. The orificed cover is intended for fabrication from plastic materials by a molding process to minimize cost and weight, maximize strength and durability and to present an aesthetically pleasing appearance. The entire assembly can be molded into a single piece unit.

Appl. No.:

7/354885

Inventors:

Mark R. Hogan - Manlius NY

Assignee:

Carrier Corporation - Syracuse NY

International Classification:

F28F 1306

US Classification:

165122

Abstract:

A stator row is disposed between a propeller fan and a heat exchanger coil, such as the outdoor or condenser coil of a packaged terminal air conditioning unit. The stator row is situated against the heat exchanger coil on the fan facing side. The stator row has a frame that substantially matches the periphery of the coil, a ring disposed coaxially with the hub of the propeller fan, and a suitable number of radial stator vanes that extend from the ring to the frame.

Appl. No.:

7/396264

Inventors:

Mark R. Hogan - Manlius NY

Assignee:

Carrier Corporation - Syracuse NY

International Classification:

F25D 1706

US Classification:

62428

Abstract:

An outdoor grill assembly for use in conjuction with an axial fan is disclosed. The assembly has cambered grill elements which increase the fan efficiency and lower the noise level associated with the fan. A grill having mirror image sections of cambered elements also controls recirculation of air from the discharge to the inlet.

Appl. No.:

7/187688

Inventors:

Donald G. Neville - Syracuse NY

Mark R. Hogan - Manlius NY

Assignee:

Carrier Corporation - Syracuse NY

International Classification:

E04F 1704

US Classification:

181224

Abstract:

A noise attenuating assembly for use in conjuction with an air conditioning unit having a sloped discharge opening is disclosed. The assembly includes a front wall and a pair of side walls forming a flow path for the conditioned air which is discharged to the space containing the unit. The assembly has a layer of sound attenuating material attached to the inside surface of the walls so that the assembly deflects and absorbs line-of-sight sound produced by the unit fan, thus reducing the noise level of the unit.
