An energy recovery system for an air handling unit includes a support frame, an energy recovery wheel, and a wheel actuator. The support frame supports the energy recovery wheel within the air handling unit. The energy recovery wheel is configured to rotate about a rotation axis during operation. The wheel actuator is configured to drive the energy recovery wheel to rotate about the rotation axis.

Various systems and apparati as well as devices and structures are provided which may be used or incorporated into air handling systems (e.g. (air) ventilation systems and apparati) for the manipulation or control of air in a enclosure such as a building, a room of a structure such as a residence, and the like. Such air handling systems (e.g. ventilation apparati or systems) may for example include an element for the transfer of heat from warm exhaust air (taken from inside an enclosure e.g. a building) to cooler exterior fresh air (drawn into the enclosure e.g. building). The present invention further relates to air handling systems (e.g. ventilation systems and apparati) which may not only exhaust stale interior air to the outside of an enclosure but as desired or necessary also intermingle a portion of such stale air with fresh air for delivery of the intermingled air back into the enclosure (during cold or warm weather). The present invention in particular relates to air handling systems (e.g. ventilation systems and apparati) which may exploit warm interior air as defrost air for defrosting the system during cool weather.

Air handling systems or devices intermingling fresh and stale air

A lamp housing assembly comprising two components, namely a mounting ring and a lamp socket holder housing. The mounting ring is snap interlockable with the lamp socket holder housing.

An air handling system for an indoor space comprising a first forced indoor air treatment component, an input indoor air duct element and an output treated air duct element respectively coupling said first forced indoor air treatment component to said indoor space, a second forced air treatment component a stale air duct element coupled to said second forced air treatment component and to said input indoor air duct, a return air duct element coupling said second forced air treatment component to said output treated air duct element characterized in that said system comprises a secondary air path means for coupling said return air duct element to said input indoor air duct element.

The present invention relates to an apparatus for ventilation systems which include an element for the transfer of heat from warm exhaust air (taken from inside a building) to cooler exterior fresh air which is drawn into the building. The present invention in particular provides an apparatus whereby, during a defrost cycle, interior air may circulate through both of the fresh air and exhaust air paths for delivery back into the building, i.e. the warm interior air, used as defrost air, may be able to circulate from the interior of the building into the ventilation apparatus and back to the interior of the building. The apparatus can thus use interior air as defrost air while diminishing or avoiding the creation of a negative air pressure in the building.

A coupling release component for releasabley coupling a shaft of a motor to a further shaft for rotation of the further shaft by the motor shaft having a rotation lock component having an axially disposed first gripping device for connecting the lock to the shaft for inducing rotation of said lock by said motor, a slip coupling component having a second gripping component disposed radially outwardly relative to the first gripping component configured to releasabley interlock with a corresponding third gripping component of a further coupling component for connecting the coupling release component to said further shaft for the rotation thereof and a resilient mounting component mounting said second gripping component to said first gripping component so as to be able to exert a radially outward force on the second gripping component so as to radially bias the second gripping component into interlocking engagement with the third gripping component.
