摘要： A mixed flow fan assembly uses induced reverse ambient air flow through the in-line motor enclosure for motor cooling, motor segregation from primary exhaust contamination, and augmentation of volumetric flow rate. Induced ambient airflow through openings in and/or around the base of the fan housing balances low pressure around the fan wheel and the inlet cone to inhibit primary exhaust recirculation and increase volumetric flow rate. Guide vanes downstream of the fan wheel are used to axially reorient radial and tangential velocity components of primary effluent flow. The geometry of the fan assembly is optimized to minimize exhaust gas recirculation and maximize overall efficiency.

摘要： An aspirating induction nozzle is designed to ensure that the discharge velocity is always at or above the governing guidelines while simultaneously leveraging physics to consistently induce fresh air with no moving parts. To achieve this, the flow rate from the fan at the inlet of the nozzle must be accelerated. A frusto-conical transitional flow impinger provides a mechanism to effectively control the flow velocity in the region from the discharge of the fan impeller through the nozzle body. The addition of the impinger provides a mechanism to ensure that flow velocities are always constant or increasing until the discharge plane of the nozzle body, thereby offering a means to optimize the design of the nozzle for the given flow and/or operational pressure drop requirements, while sustaining a tuned venturi effect for steadfast operation in a dynamic environment.

摘要： Optimized conditioning of Information and Communication Technology (ICT) centers containing sensible heat generating equipment is achieved by indirect air-side economizing. In this process, the conditioned primary air stream is recirculated through a plate-type cross-flow heat exchanger, in which the cross-flow consists of a completely segregated cooler secondary ambient air stream. The air-to-air cross-flow heat exchanger comprises a series of parallel square or rectangular plates, which define a series of orthogonally alternating air passageways. This cross-flow design effectively prevents the mixing or blending of the primary and secondary air streams and thus avoids the efficiency losses and process airstream cross-contamination due to leakage, which is inherent in wheel type heat exchangers. The unique modular tunnel design of the cross-flow plate heat exchanger arrangement offers unit scalability and adjustability for various capacities and space demands. Real-time sensing of thermal demands and variable capacity control, coupled with on-demand mechanical cooling and humidification provisions, facilitate continuous operational optimization in all demands and ambient conditions.

摘要： A variable volume induction nozzle is designed for use with a variable speed fan, where fan speed is adjusted in response to variable exhaust gas flow volume in order to conserve energy. In order to maintain a minimum exhaust discharge velocity to ensure adequate plume height, an axially-extendable, upwardly tapered flow-impinging pod within the nozzle creates a variable annular nozzle outlet opening. As opposed to a circumferentially-constricted outlet opening, the variable annular outlet produces a uniform discharge velocity profile conducive to the induction of ambient air through a windband.

摘要： High plume lift is particularly critical with regard to exhaust gases from potentially contaminated sources, such as laboratories and other facilities in which chemical processes produce noxious and/or hazardous fumes. To insure that potentially contaminated exhaust reaches a minimum altitude to avoid downwash, many applicable environmental and building codes and standards specify a minimum discharge velocity from an exhaust n discharge location. Therefore, an aspirating induction nozzle is designed to ensure that the discharge velocity is always at or above the governing guidelines while simultaneously leveraging physics to consistently induce fresh air with no moving parts. To achieve this, the flow rate from the fan at the inlet of the nozzle must be accelerated. A frusto-conical transitional flow impinger provides a mechanism to effectively control the flow velocity in the region from the discharge of the fan impeller through the nozzle body. The addition of the impinger provides a mechanism to ensure that flow velocities are always constant or increasing until the discharge plane of the nozzle body, thereby offering a means to optimize the design of the nozzle for the given flow and/or operational pressure drop requirements, while sustaining a tuned venturi effect for steadfast operation in a dynamic environment.

摘要： A modified version of an induction nozzle having a central “see-through” passive zone protects the induction ports from crosswind disruption. Modified features include: (i) a full-length wind band extending below the induction port inlets; (ii) multiple full-length mounting brackets, which impede circumferential crosswind flow around the nozzle; (iii) a transverse induction port separation plate, orthogonal to the centerlines of the induction ports; and (iv) elimination of one induction port opening.

摘要： An aspirating induction nozzle for vertical connection to the outlet of a pressurized exhaust gas flow comprises a central nozzle surrounded by a wind band and one or more guide vanes. Ambient air is induced into a mixing zone within the central nozzle to dilute the primary effluent and increase the volumetric discharge flow rate to achieve greater plume lift. The mixing zone within the central nozzle is protected from crosswind influences, which would otherwise diminish plume lift.
