Abstract:
A fan is provided for use with a casing having a bellmouth and a conduit portion. The fan has a hub, a number of blades extending from the hub, and a shroud. In cooperation with the casing and the conduit portion surrounding the shroud, the shroud has means for generating a separation bubble effective to limit a recirculation flow.
Abstract:
A discharge pipe (12A) for connecting a compressor (16) with a condenser (18) in a vapor-compression system (10) comprises an intake segment (38), a muffler (14), a splitter segment (39) and first and second discharge segments (44A, 44B). The intake segment (38) is configured to connect to a discharge port (36) of the compressor (16) and receive compressed refrigerant flow. The muffler (14) is connected to the intake segment (38) for attenuating pulsations within the compressed refrigerant flow. The splitter (39) segment is connected to the muffler (14) and configured to divide the compressed refrigerant flow into first and second branches. The first discharge segment (44A) connects to the splitter (39) to receive the first branch and is configured to connect to the condenser (18) at a first position (37A). The second discharge segment (44B) connects to the splitter (39) to receive the second branch and is configured to connect to the condenser (18) at a second location (37B).
Abstract:
A fan assembly has a central metallic element and a polymeric fan. The polymeric fan has a hub carrying the central metallic element and has a plurality of blades extending from the hub. The central metallic element has a central longitudinal aperture and a lateral surface. The central metallic element lateral surface is of substantially uniform substantially square section along a majority of a length of the central metallic element.
Abstract:
A muffling apparatus (100) having a first, muffling segment (1010) and a second (1020), non-muffling segment is provided for placement within an oil separator of refrigeration or cooling system, wherein the apparatus has a non-straight shape and a lumen defined therein to allow for noise-creating pressure pulsations/waves to come into contact with absorbing material (120) of the muffling segment (1010) in order to attenuate the energy of the pressure waves/pulsations into heat and thus reduce oil separator vibrations caused thereby.

Abstract:
A fan motor support bracket has a central body portion and first and second end portions upwardly offset from the central body portion. First and second transition portions extend respectively between the first and second end portion and first and second ends of the central body portion. The central body portion has a base and first and second sidewalls extending generally upward from the base. The first sidewall has at least one relief for accommodating a mounting ear of the motor.
