Energy reducing retrofit method and apparatus for a constant volume HVAC system

An energy-reducing method and apparatus for retrofitting a single zone, constant volume HVAC system, with or without an economizer, that provides heating, cooling, and ventilation to occupants within a building space. The present invention includes the introduction of a programmable logic controller and variable frequency drive (VFD) that takes control of the existing fan, heating, cooling, and optional economizer operation. The reduction of the fan speed in the ventilation mode when the 100% operation is not needed saves significant energy of the existing constant volume HVAC system where the fan motor is designed to run 100% of the time.

Handle mechanism for an HVAC damper actuator

A damper system may include a handle mechanism for use with a damper actuator system. Illustratively, the handle mechanism may include a drive gear mechanism, a handle, a housing, and a spring, and may be actuated to set a crack pressure for the damper system. The handle may connect to the drive gear mechanism at a drive gear arm of the drive gear mechanism and may flip over or about the drive gear arm to move from a first position to a second position. In some instances, once the handle is in the second position, a force may be applied thereto to disengage the drive gear from a stop member and thereafter, the handle may be rotated to change the crack pressure of the damper system.
