摘要： An improved outlet guide vane system is disclosed for axial flow fans. Construction details are described which reduce losses in the end wall regions of the vanes, particularly for axial flow fans operating at low flow coefficient with strong localized swirl associated with upstream rotor tip clearance flows. In the preferred embodiment, the vane spanwise airfoil stacking line is approximately straight, while leaning circumferentially toward the incoming swirl flow over the majority of the radial span. The stacking line then curves abruptly in the opposite direction over the radially outboard spanwise portion, so as to lean away from the incoming swirl at the vane tip station. The radially outboard portion of the vanes simultaneously include a gradual increase in vane stagger angle, vane camber angle and vane chord. The vane may also include an axial sweep component.

摘要： A bus rooftop air conditioning system is made up of one or more self-contained modules having one or more evaporator sections and one or more condenser sections, with each extending transversely across the width of the bus, and with the evaporator sections fluidly communicating with both a common return air opening and a common supply air opening of the bus. The modules may be of a single unit configuration with a single condenser section and a single evaporator section or they may be of a double unit configuration having two condenser sections and two evaporator sections. The total capacity requirements are met by combining the use of single units and double unit configuration, with each of the evaporator sections communicating with a single return air opening and a single supply air opening in a bus.

摘要： A module is provided for attachment to the roof of a bus and includes all of the necessary components for conditioning the return air from the passenger compartment and delivering conditioned air thereto. A plurality of modules can be mounted in various relationships to collectively provide the total capacity required by the bus. Each module includes an evaporator section, a condenser section and a power section including a compressor and an inverter. The evaporator sections have a return air compartment that extends a substantial distance across the roof of the bus such that a single design can meet the needs of various return air duct installations of various types of buses. Provision is made for the selective mixing of return air with fresh air, with the mixture then being passed by the evaporator blower through the evaporator coils and into the supply air ducts. The frames of the modules are attached to the roof of the bus by rails which are properly spaced to accommodate the module frames and allow their selective longitudinal placement.

摘要： A rotating shroud is located on the suction side of the tips of a propeller fan and coacts with an inlet orifice to provide the physical separation between suction and discharge when the unit is in operation. The pressure differential across the fan tends to cause the condensate to move towards the suction side and into the path of the slinger (rotating shroud). The slinger then becomes wetted by the condensate, thereby picking up the condensate and slinging it into the region between the fan and the coil. The condensate is then evaporated upstream or within the coil, improving coil effectiveness.

摘要： An axial fan assembly including a casing wall with a forward facing step formed therein. Formed on the surface of the step is a plurality of circumferentially spaced wedges which are formed and positioned so as to reduce the swirl flow within the clearance gap between the fan rotor and casing. The wedges are formed so the swirling backflow first encounters a circumferentially tapered face and then an abrupt axially oriented face, thereby substantially removing the swirl component. The wedges have a favorable effect on the flow stability of the fan, thereby extending its operating range. Variations include a fan rotor with a rotating shroud with an outwardly extending portion overlapping the step, and a bellmouth piece at the casing inlet.

摘要： An air conditioning unit having an indoor section and an outdoor section separated by dividing wall. The outdoor heat exchanger and fan are enclosed within a housing that is split into a stationary lower wall section and a removable upper wall section which, when removed, provides ready access to the outdoor heat exchanger. A hole is placed in the bottom of the lower wall section in front of the fan so that condensate can be drawn into the unit by the fan and distributed over the heat exchanger surfaces. Vanes are placed on the inside wall of the housing to enhance the distribution of the condensate.
