Abstract: Modular air handling systems are presented including: at least one blade, where the at least one blade includes: an intake section for receiving an airflow including: an intake air portion, a filter portion, a coil portion, and a head portion; a removable fan module, where the removable fan module includes: at least one low velocity axial fan; and an isolation damper; a discharge section for discharging the airflow including: a discharge air portion; and a number of sensors for receiving process data, discharge data, and environmental data; and a control system for processing data from the number of sensors to provide a closed loop control of the modular air handling system, where each blade operates independently, and where the at least one low velocity axial fan for each removable fan module are controlled by a single control signal.

Abstract: This patent application covers design and modular manufacturing techniques for an economical air handler and exhaust fan product line that delivers better energy performance, acoustical performance, space utilization, and operational efficiency than is available in today's marketplace. An axial fan is positioned within airflow guides designed to minimize turbulence to reduce acoustics and energy consumption. The specific arrangement of air filters, heating and cooling coils, airflow guides, sound attenuating surfaces, fan modules, control panels, backdraft dampers and isolation dampers enables the stacking of modular units to meet air handler capacity requirements with inherent redundancy. In some configurations, the air handler described provides complete redundancy for a no-shutdown system that will reduce HVAC energy requirements to a lower level and provide a greater operating range than is available in today's market.

Abstract: The integrated laboratory light (lablight) fixture is a sealed ceiling mounted fixture that combines air outlets, lighting and other devices for use in laboratory, clean room, healthcare, educational, and other facilities requiring critical airflow control. The integrated lablight is made for a central location in the lab to eliminate room scale eddies and cross drafts along with the hood challenges they present. The combining of most ceiling devices in one fixture results in a safer environment with greater access for above ceiling maintenance, as well as less expensive facility capital costs. The fixture design also minimizes shadows at the work surface, and promotes temperature stability for temperature sensitive equipment.

Abstract: A ceiling mounted fixture, which includes at least one longitudinal arrangement of at least one air vent adapted to receive an air supply, and at least two longitudinal arrangements of at least one light source. The at least one longitudinal arrangement of at least one air vent is positioned between the at least two longitudinal arrangements of light sources. The fixture also includes a plenum with an airflow guide adapted to receive the air supply from the at least one longitudinal arrangement of at least one air vent.
